More surprisingly, green pills have the strongest placebo effect on relieving anxiety, whereas yellow pills work best for depression. Moreover, a pill’s placebo effect is increased if it is given by a doctor wearing a white coat, but it is reduced if it is administered by a doctor wearing a T-shirt, and it is even less effective if given by a nurse. Large tablets offer a stronger placebo effect than small tablets…unless the tablets are very, very small. Not surprisingly, tablets in fancy branded packaging give a bigger placebo effect than those in plain packets. Of course, all of the above statements refer to the average patient, because the actual placebo effect for a particular patient depends entirely on the belief system and personal experiences of that individual. This variability of placebo effect among patients, and its potentially powerful influence on recovery, means that it can be a highly misleading factor when it comes to assessing the true efficacy of a treatment.

In other words, a genuine medicine offers a benefit that is largely due to the medicine itself and partly due to the placebo effect, whereas a fake medicine offers a benefit that is entirely due to the placebo effect. As the placebo effect arises out of the patient’s confidence in the treatment, Haygarth wondered about the factors that would increase that confidence and thereby maximize the power of the placebo. He concluded that, among other things, the doctor’s reputation, the cost of the treatment and its novelty could all boost the placebo effect. Many physicians throughout history have been quick to hype their reputations, link high cost with medical potency and emphasize the novelty of their cures, so perhaps they were already aware of the placebo effect. In fact, prior to Haygarth’s experiments, it seems certain that doctors had been secretly exploiting it for centuries.

It is interesting to note that the placebo effect is particularly good at addressing issues such as pain, swelling, fever, lethargy and loss of appetite, so perhaps the placebo effect is partly the consequence of an innate ability to block the acute phase response at a fundamental level, possibly by the power of expectation. The placebo effect may be linked to either conditioning or expectation or both, and there may be other even more important mechanisms that have yet to be identified or fully appreciated. While scientists strive to establish the scientific basis of the placebo effect, they have already been able to ascertain, by building on Haygarth’s early work, how to maximize it. It is known, for instance, that a drug administered by injection has a bigger placebo effect than the same drug taken in pill form, and that taking two pills provokes a greater placebo response than taking just one.

We know that the colour of pills, their packaging, how much you pay for them and even the beliefs of the people handing the pills over are all important factors. We know that placebo operations can be effective for knee pain, and even for angina. The placebo effect works on animals and children. It is highly potent, and very sneaky, and you won’t know the half of it until you read the ‘placebo’ chapter in this book. So when our homeopathy fan says that homeopathic treatment makes them feel better, we might reply: ‘I accept that, but perhaps your improvement is because of the placebo effect,’ and they cannot answer ‘No,’ because they have no possible way of knowing whether they got better through the placebo effect or not. They cannot tell. The most they can do is restate, in response to your query, their original statement: ‘All I know is, I feel as if it works. I get better when I take homeopathy.’

Let’s imagine we’re talking—maybe even arguing—with someone who thinks that homeopathy works, someone who feels it is a positive experience, and who feels they get better, quicker, with homeopathy. They would say: ‘All I know is, I feel as if it works. I get better when I take homeopathy.’ It seems obvious to them, and to an extent it is. This statement’s power, and its flaws, lie in its simplicity. Whatever happens, the statement stands as true. But you could pop up and say: ‘Well, perhaps that was the placebo effect.’ Because the placebo effect is far more complex and interesting than most people suspect, going way beyond a mere sugar pill: it’s about the whole cultural experience of a treatment, your expectations beforehand, the consultation process you go through while receiving the treatment, and much more. We know that two sugar pills are a more effective treatment than one sugar pill, for example, and we know that salt-water injections are a more effective treatment for pain than sugar pills, not because salt-water injections have any biological action on the body, but because an injection feels like a more dramatic intervention.

We are human, we are irrational, we have foibles, and the power of the mind over the body is greater than anything you have previously imagined. 5 The Placebo Effect For all the dangers of CAM, to me the greatest disappointment is the way it distorts our understanding of our bodies. Just as the Big Bang theory is far more interesting than the creation story in Genesis, so the story that science can tell us about the natural world is far more interesting than any fable about magic pills concocted by an alternative therapist. To redress that balance, I’m offering you a whirlwind tour of one of the most bizarre and enlightening areas of medical research: the relationship between our bodies and our minds, the role of meaning in healing, and in particular the ‘placebo effect’. Much like quackery, placebos became unfashionable in medicine once the biomedical model started to produce tangible results.

When patients get better by ingesting a sugar pill, medicine defines it as the placebo effect. My friend Rob Williams, founder of PSYCH-K, an energy-based psychological treatment system, suggests that it would be more appropriate to refer to it as the perception effect. I call it the belief effect to stress that our perceptions, whether they are accurate or inaccurate, equally impact our behavior and our bodies. I celebrate the belief effect, which is an amazing testament to the healing ability of the body/mind. However, the “all in their minds” placebo effect has been linked by traditional medicine to, at worst, quacks or, at best, weak, suggestible patients. The placebo effect is quickly glossed over in medical schools so that students can get to the real tools of modern medicine like drugs and surgery. This is a giant mistake. The placebo effect should be a major topic of study in medical school.

The message from the drug companies is clear to me: if you can’t beat placebo pills fairly, simply remove the competition! The fact that most doctors are not trained to consider the impact of the placebo effect is ironic because some historians make a strong case that the history of medicine is largely the history of the placebo effect. For most of medical history, doctors did not have effective methods to fight disease. Some of the more notorious treatments once prescribed by mainstream medicine include bloodletting, treating wounds with arsenic, and the proverbial cure-all, rattlesnake oil. No doubt some patients, the conservatively estimated one third of the population who are particularly susceptible to the healing power of the placebo effect, got better with those treatments. In today’s world, when doctors wearing white coats deliver a treatment decisively, patients may believe the treatment works—and so it does, whether it is a real drug or just a sugar pill.

She insisted that the researchers double-check their records to make absolutely sure she wasn’t on the drug. Nocebos: The Power of Negative Beliefs While many in the medical profession are aware of the placebo effect, few have considered its implications for self-healing. If positive thinking can pull you out of depression and heal a damaged knee, consider what negative thinking can do in your life. When the mind, through positive suggestion improves health, it is referred to as the placebo effect. Conversely, when the same mind is engaged in negative suggestions that can damage health the negative effects are referred to as the nocebo effect. In medicine, the nocebo effect can be as powerful as the placebo effect, a fact you should keep in mind every time you step into a doctor’s office. By their words and their demeanor, physicians can convey hope-deflating messages to their patients, messages that are, I believe, completely unwarranted.

Moseley argued that his study had been carefully designed and carried out. “Surgeons…who routinely perform arthroscopy are undoubtedly embarrassed at the prospect that the placebo effect—not surgical skill—is responsible for patient improvement after the surgeries they perform. As you might imagine, these surgeons are going to great lengths to try to discredit our study.” Regardless of the extent to which you believe the results of this study, it is clear that we should be more suspicious about arthroscopic surgery for this particular condition, and at the same time increase the burden of proof for medical procedures in general. IN THE PREVIOUS chapter we saw that expectations change the way we perceive and appreciate experiences. Exploring the placebo effect in this chapter, we’ll see not only that beliefs and expectations affect how we perceive and interpret sights, tastes, and other sensory phenomena, but also that our expectations can affect us by altering our subjective and even objective experiences—sometimes profoundly so.

Very interesting—considering that Veladone was just a capsule of vitamin C. FROM THIS EXPERIMENT, we saw that our capsule did have a placebo effect. But suppose we priced the Veladone differently. Suppose we discounted the price of a capsule of Veladone-Rx from $2.50 to just 10 cents. Would our participants react differently? In our next test, we changed the brochure, scratching out the original price ($2.50 per pill) and inserting a new discount price of 10 cents. Did this change our participants’ reaction? Indeed. At $2.50 almost all our participants experienced pain relief from the pill. But when the price was dropped to 10 cents, only half of them did. Moreover, it turns out that this relationship between price and placebo effect was not the same for all participants, and the effect was particularly pronounced for people who had more experience with recent pain.

placebo effect, the scientific method

In thinking about how to review the subject it occurred to me that the best approach might be to consider each treatment modality from the standpoint of its intended purpose. Of course, all treatments are supposed to relieve pain but the important question is how. What is the rationale for each treatment? Before we get into this let’s review once more the subject of the placebo effect because 120 The Traditional (Conventional) Treatments 121 of its crucial importance in any discussion of treatment. THE PLACEBO EFFECT A placebo is any treatment that produces a good therapeutic result despite the fact it has no intrinsic therapeutic value. A sugar pill is the classic example. It is clear that the desirable outcome must be attributed to the ability of the mind to manipulate the various organs and systems of the body. In order to do this the mind must believe in the efficacy of the treatment and/or the treater.

One can say the same thing about this as for the two above. However, there is a real question whether this functions as anything but a placebo. A group at the Mayo Clinic published a study in 1978 in which they demonstrated that a placebo worked equally well (G. Thorsteinsson, H. H. Stonnington, G. K. Stillwell and L. R. Elveback, “The Placebo Effect of Transcutaneous Electrical Stimulation,” Pain, Vol. 5, p. 31). When there is prolonged relief as a result of any of these treatments one must suspect a placebo effect; there can be no other explanation, for they do not attack the cause of the problem. Treatments to Promote Relaxation To the prescribers of treatments to promote relaxation I would put the question, “To what end?” “What is your purpose in trying to relax the person?” “What do you hope to accomplish?” There is considerable fuzziness about this subject in the area 124 Healing Back Pain of pain relief.

It took that long for me to fully break with all the old traditions in which I had been schooled. Conceptually, prescribing physical therapy contradicts what we have found to be the only rational way to treat the problem; that is, by teaching, and thereby invalidating, the process where it begins— in the mind. Further, it had become obvious that some patients had put all their confidence in the physical therapy (or therapist) and were having placebo cures (see “The Placebo Effect”), which meant that sooner or later they would be in pain again. The principle is that one must renounce any structural explanation either for the pain or its cure, or the symptoms will continue. Manipulation, heat, massage, exercise and acupuncture all presuppose a physical disorder that can be treated by some physical means. Unless that whole concept is repudiated, the pain and other symptoms continue.

Because there are many settings in which people with a problem, given a placebo, report sizable improvement on average when they are queried (see #3), many scientists have accepted that “placebo effects”—of suggestion—are both substantial and widespread in the scope of what they benefit. The Danish researchers Asbjørn Hróbjartsson and Peter C. Götzsche conducted a systematic review of studies that compared a placebo to no treatment. They found that the placebo generally does . . . nothing. In most instances, there is no placebo effect. Mild “placebo effects” are seen, in the short term, for pain and anxiety. Placebo effects for pain are reported to be blocked by naloxone, an opiate antagonist—specifically implicating endogenous opiates in pain placebo effects, which would not be expected to benefit every possible outcome that might be measured. 3. When hearing that people given a placebo report improvement, scientists commonly presume this must be due to the “placebo effect,” the effect of expectation/suggestion.

Unfortunately, bypassing the need to articulate the conditions and assumptions on which validity of the construct rests may lead to bypassing consideration of whether these conditions and assumptions legitimately apply. Use of the term can then, far from fostering sound discourse, serve to undermine it. Take, for example, the “placebo” and “placebo effects.” Unpacking the terms, a placebo is defined as something physiologically inert but believed by the recipient to be active or possibly so. The term “placebo effect” refers to improvement of a condition when someone has received a placebo—improvement due to the effects of expectation/suggestion. With these terms ensconced in the vernacular, dece(i)bo effects associated with them are much in evidence. Key presumptions regarding placebos and placebo effects are more typically wrong than not. 1. When hearing the word “placebo,” scientists often presume “inert” without stopping to ask, What is that allegedly physiologically inert substance?

The scientists attributed this to a placebo effect. But what’s to say that the subjects weren’t simply telling the scientists what they thought the scientists wished to hear? Denise Grady, writing for the New York Times, has noted: “Growing up, I got weekly hay fever shots that I don’t think helped me at all. But I kept hoping they would, and the doctor was very kind, so whenever he asked if I was feeling better, I said yes . . .” Such desire to please (a form, perhaps, of “social approval” reporting bias) made for fertile ground in which to operate and create what was interpreted as a placebo effect, which implies actual subjective benefit to symptoms. One wonders whether so great an error of presumption would operate were there not an existing term (“placebo effect”) to signify the interpretation the Harvard group chose among the suite of other compelling possibilities.

As you can see from the light dashed line in the graph, this set of patients experienced the least amount of pain—even lower than that experienced by the group that got the anesthetic! To those who are familiar with placebo effects, these results won’t come as a surprise. Placebo effects are so prevalent in medical contexts that any test of the effectiveness of a new drug involves comparing it with a control condition in which a placebo drug, like a sugar pill, is given to patients. What these placebo effects tell us is that our beliefs can shape our reality. If you think that a pill is going to cure a disease, there seems to be an objectively greater chance that it will cure the disease than if you think that it won’t. As it turns out—and here’s where it gets really interesting—placebo effects are not restricted to medical contexts; they occur in other contexts as well. In marketing, findings show that if you believe imbibing a particular drink will improve your cognitive skills, it will.

Although there are some questions about whether the original set of studies conducted by Beecher documented evidence for the placebo effect or some other effects (see, for example, Kienle and Kiene 1997), there is little doubt that the effect is believed to be prevalent, particularly in the medical domain (see Hróbjartsson & Norup 2003). That said, however, there is ongoing debate about the potency and prevalence of the effect (see Hróbjartsson et al. 2001; Moerman et al. 2002; Wampold et al. 2005; and Hróbjartsson et al. 2010).

Unfortunately, however, these tests suffer from two serious biases. First, these tests don’t fully take into account the placebo effect which occurs when you get better all by yourself simply because you think the medicine you took is supposed to make you better. For example, when my young son bumped his head, I took advantage of the placebo effect by telling him that the Vaseline I put on his head would make him feel better. I even told him that I didn’t want to put too much of the medicine on him because it was “extremely powerful,” and I didn’t think he could handle it. When he predictably objected to my moderation, I “gave in” and put extra salve on his boo-boo. My son claimed that the medicine made him feel better. The placebo effect is a widespread and mysterious phenomenon, and there’s a reasonable chance that it also works for cognitive-enhancement drugs.

Double-blind tests understate the efficacy of cognitive enhancement drugs to the extent that the placebo effect holds. For example, assume that: A. If you took a drug and were truthfully told it was a real drug, your performance would improve by 15 percent. This 15 percent improvement comes from both the inherent medical value of the pill and the placebo effect. B. If you took a real drug and were told that there was a 50 percent chance that it was real (as is the case when you participate in a double-blind drug trial), then you would experience a 10 percent performance improvement.265 C. If you took a sugar pill and were told that there was a 50 percent chance that it was real, then you would experience a 4 percent performance improvement, all of it coming from the placebo effect. A double-blind test would compare the performance improvements in (B) and (C) and claim that the drug yielded a 6 percent improvement.

A double-blind test would compare the performance improvements in (B) and (C) and claim that the drug yielded a 6 percent improvement. But if you used the drug outside of this experiment, you would see a 15 percent improvement, which shows that factoring in placebo effects likely causes double-blind tests to underestimate the power of cognitive-enhancement drugs. “File-drawer effects,” however, result in double-blind tests overestimating the efficacy of cognitive-enhancement drugs. Suppose that three groups of scientists investigate the effects of some compound: 1.The first group finds that the compound made test subjects much smarter. 2.The second group finds that using the compound didn’t have any effect on the test subjects. 3.The third group gave up the experiment halfway through because the results didn’t seem to be interesting. The first group will have the easiest time getting published because their results are the most interesting and important.

“Surgeons . . . who routinely perform arthroscopy are undoubtedly embarrassed at the prospect that the placebo effect—not surgical skill—is responsible for patient improvement after the surgeries they perform. As you might imagine, these surgeons are going to great lengths to try to discredit our study.” Regardless of the extent to which you believe the results of this study, it is clear that we should be more suspicious about arthroscopic surgery for this particular condition, and at the same time increase the burden of proof for medical procedures in general. IN THE PREVIOUS chapter we saw that expectations change the way we perceive and appreciate experiences. Exploring the placebo effect in this chapter, we’ll see not only that beliefs and expectations affect how we perceive and interpret sights, tastes, and other sensory phenomena, but also that our expectations can affect us by altering our subjective and even objective experiences—sometimes profoundly so.

Very interesting—considering that Veladone was just a capsule of vitamin C. FROM THIS EXPERIMENT, we saw that our capsule did have a placebo effect. But suppose we priced the Veladone differently. Suppose we discounted the price of a capsule of Veladone-Rx from $2.50 to just 10 cents. Would our participants react differently? In our next test, we changed the brochure, scratching out the original price ($2.50 per pill) and inserting a new discount price of 10 cents. Did this change our participants’ reaction? Indeed. At $2.50 almost all our participants experienced pain relief from the pill. But when the price was dropped to 10 cents, only half of them did. Moreover, it turns out that this relationship between price and placebo effect was not the same for all participants, and the effect was particularly pronounced for people who had more experience with recent pain.

Isn’t this what we go to doctors for—to learn, from someone who knows, the true nature of our suffering, to find out whether that nagging pain is the leading edge of something horrible or just a random twinge, to find out if our persistent malaise is grief or depression or maybe even a malfunctioning thyroid? Even before we ask for remedy, this is what we ask of our doctors: to lay bare the beginnings of our suffering, to elicit our present crisis, to tell us what is going to happen in the end. Without that story, we might not take their pills, and—since so much of our response to medication is the result of placebo effects, and placebo effects in turn depend on the patient’s belief in his or her doctor—the pills might not work. On the other hand, most of us won’t accept just any tale about our woes. We want our doctors’ stories about us to be based in fact, not opinion. We want them to make sense, which, if they start telling us that grieving the loss of a parent is an illness, they don’t. That’s why the bereavement exclusion was necessary: without it, the DSM loses its credibility, and the doctors who use it cannot perform their healing magic

He lived before autonomy and equality were expectations for a good life, before universal justice was the hallmark of a good society, and before a couple thousand years of history had revealed what can happen when people with power—even virtuous people—act in the supposed interests of those with none. Not that Frances’s concern about the effect of diagnostic squabbling on patients was less than beneficent or only about maintaining psychiatry’s dominion over our inner lives. “Like most medical specialties4, our field depends heavily on placebo effects,” he pointed out. And pills aren’t the only way to deliver the placebo effect. Even if “the diagnostic label is just a description, and not really an explanation for what has gone wrong,” Frances says, still it is crucial to treatment. Delivering a diagnosis gives us solace: that we are not making it up, that the doctor understands, that there are others like us, that there is hope for a cure. “If you puncture that noble lie,” Frances warned me, “you’ll be doing a disservice to our patients.”

And maybe they did, because at least for a little while you felt better; but then you got tired of feeling numb14, of gaining weight, of not wanting sex and not being able to have an orgasm even if you did; and then you tried to get off the drugs only to find that your brain off drugs is an unruly thing, that your old difficulties returned or new ones arose when you stopped taking them. Which might mean, you told yourself, that you indeed have that disease, but every once in a while—when you read about the placebo effect15, or you hear that this chemical imbalance does not, as far as doctors know16, really exist, or when you look at the DSM and realize that there are more than seventy combinations of symptoms17 that can result in this one diagnosis and that any two people with the diagnosis may have only one symptom in common—you wonder whether what your doctor told you is true and whether you have now changed your brain chemistry, perhaps irreversibly, to cure a disease that doesn’t exist.

Anyone who works face-to-face with patients knows how often it is necessary to seek new information before making a clinical decision. Doctors have spent time in libraries since libraries were invented. In general, we don't put a patient on a new drug without evidence that it is likely to work. Apart from anything else, such off-licence use of medication is, strictly speaking, illegal. Surely we have all been practising EBM for years, except when we were deliberately bluffing (using the ‘placebo’ effect for good medical reasons), or when we were ill, overstressed or consciously being lazy? Well, no, we haven't. There have been a number of surveys on the behaviour of doctors, nurses and related professionals. It was estimated in the 1970s in the USA that only around 10–20% of all health technologies then available (i.e. drugs, procedures, operations, etc.) were evidence-based; that figure improved to 21% in 1990, according to official US statistics [4].

Pharmaceutical reps do not tell nearly as many lies as they used to (drug marketing has become an altogether more sophisticated science), but as Goldacre [9] has shown in his book ‘Bad Pharma’, they still provide information that is at best selective and at worst overtly biased. It often helps their case, for example, to present the results of uncontrolled trials and express them in terms of before-and-after differences in a particular outcome measure. Reference to section ‘Cross-sectional surveys’ and the literature on placebo effects [10] [11] should remind you why uncontrolled before-and-after studies are the stuff of teenage magazines, not hard science. Dr Herxheimer, who edited the Drug and Therapeutics Bulletin for many years, undertook a survey of ‘references’ cited in advertisements for pharmaceutical products in the leading UK medical journals. He tells me that a high proportion of such references cite ‘data on file’, and many more refer to publications written, edited and published entirely by the industry.

One way to motivate action, then, is to make people feel as though they’re already closer to the finish line than they might have thought. 3. The researchers Crum and Langer chalked up the maids’ weight loss to a placebo effect. In other words, they concluded that awareness of the exercise value of their activities triggered the weight loss, independent of any physical changes in the maids’ behavior. The placebo effect is one of the most reliable phenomena in modern medicine, so at first glance, this explanation seems reasonable. We’ve all got friends who swear by the healing powers of questionable remedies—stinkweed supplements or goat horn extract. Maybe the maids got a similar mental boost from their new knowledge. But notice what placebo-effect situations have in common: They apply to conditions that are self-reported. You take a pain pill, and the doctor asks you afterward, “How much pain do you feel now?”

So it’s understandable (though still fundamentally weird) that the patients who get placebos, rather than Advil or Prozac, might report feeling a bit better. But this isn’t one of those situations. No one was asking these maids how they felt or whether they perceived themselves to be healthier. The maids simply stepped onto a scale, and the scale reported a lower weight. Scales aren’t subject to placebo effects. OK, but if you’ve suddenly discovered that you’re a good exerciser, might not that trigger some kind of mind-body effect? Couldn’t it kick your metabolism into overdrive or something? It’s not impossible, we suppose, but let’s be honest: If the power of thinking could indeed make you skinnier, that would be a scientific revelation on par with cold fusion (as well as a billion-dollar self-help book—Think Yourself Thin).

Positive emotion also makes it easier for people to make connections among dissimilar ideas, and it makes them less likely to slip into an “us versus them” mentality. All of these tendencies—flexible problem solving, innovative solutions, less political infighting—would be very useful in a change situation. Chapter Six A study of hotel maids. See Alia J.

What helps overcome some of our self-fooling in an N=1 experiment in the new era of self-tracking is automatic instrumentation (having a sensor make the measurement many times for long periods so it is “forgotten” by the subject) and being able to track many variables at once to distract the subject, and then using statistical means later to try to unravel any patterns. We know from many classic large population studies that often the medicine we take works because we believe it will work. This is otherwise known as the placebo effect. These quantified-self tricks don’t fully counter the placebo effect; rather they work with it. If the intervention is producing a measurable improvement in you, then it works. Whether this measurable improvement is caused by the placebo effect doesn’t matter since we only care what effect it has on this N=1 subject. Thus a placebo effect can be positive. In formal studies, you need a control group to offset your bias toward positive results. So in lieu of a control group in an N=1 study, a quantified-self experimenter uses his or her own baseline. If you track yourself long enough, with a wide variety of metrics, then you can establish your behavior outside (or before) the experiment, which effectively functions as the control for comparison

In 1920, Serge Voronoff, a Russian doctor based in Paris, started transplanting parts of chimps in an effort to restore youth to men under the theory that the sex glands drove energy.58 We have seen that the linking of sex and youth is not a new idea, but the use of animal transplants in this way was fairly novel. Many of Dr. Voronoff’s patients died, but those who didn’t thought they actually saw results (most likely a placebo effect). And he wasn’t the only one wedded to this theory. In America, doctors in prisons were experimenting with similar techniques. Eventually, some well-known people underwent similar procedures, including former middleweight champion boxer Frank Klaus and Irish poet William Butler Yeats.59 Indeed, Yeats felt the placebo effect so strongly that the sixty-nine-year-old entered into an affair with a twenty-seven-year-old actress.60 We now know that grafting animal tissue onto humans is useless because the body rejects it, but we have also learned a lot more about the endocrine system and the impact that hormones have on our bodies.

After all, it was lack of willpower that had gotten Adam and Eve into the perilous position of eating from the tree of knowledge in the first place, so maybe willpower was the cure for their descendants. “The implication,” argue S. Jay Olshansky and Bruce A. Carnes in their book The Quest for Immortality, “is that by reasserting control over the mind, the supernatural power taken by God could be restored.” 11 This idea of mind over matter was, and still is, shared by many as powerful medicine and certainly isn’t limited to the religious sphere. The very fact of a placebo effect, in which people’s symptoms subside simply because they think they are taking a drug when they are instead taking a sugar pill (the placebo), is a reminder of how powerful the mind can be. Such power led Irish writer George Bernard Shaw to advocate for the Lamarckian idea that characteristics could be acquired and passed down through generations. Hence, a giraffe’s neck evolved over time, he reasoned, as members of each generation reached up, willing themselves to get the leaves on higher and higher branches.

There are cases when we want to be tricked by our messengers, even though we don’t quite want to describe the process to ourselves in those terms. The more expensive wine really can taste better, simply because it is more expensive, and we want to keep that as one of our pleasures in life. It’s what helps to make “special occasions” feel so special, namely that we went to considerable trouble to do something. In part our expectations make the difference a real one through a kind of placebo effect. But if we have chosen that placebo effect, such a “trick” can bring real human benefits. Dan Ariely did a famous study where he showed that more expensive pain relief medication, even of similar quality, does a better job at alleviating pain. Or maybe I love my wife more because I had to court her with great passion. These are often opportunities rather than problems. These results, by the way, aren’t all new and revolutionary but rather they reflect some age-old wisdom.

There are plenty of studies that measure the economic “rate of return” on education and these studies come up with fairly high numbers. In other words, if you graduate from college, or with a postgraduate degree, you will earn more. But what are these studies comparing education to? It’s now well-known in the medical literature that a medicine needs to be compared to a placebo, rather than to simply doing nothing. Placebo effects can be very powerful and many supposedly effective medicines do not in fact outperform the placebo. The sorry truth is that no one has compared modern education to a placebo. What if we just gave people lots of face-to-face contact and told them they were being educated? I’m not sure I want to know the answer to that question. Maybe that’s what current methods of education already consist of.

Weil believes in what he calls “stoned thinking” and in intuition as a source of knowledge. This he juxtaposes with “straight” or “ordinary” thinking. You know, the type weighed down by silly rules and conventional thought. Like every alternative healer, Weil believes in the supremacy of faith and compassion. I certainly wouldn’t argue against faith (if only because for many people it provides the single form of alternative medicine that seems clearly to work, a placebo effect). And here is my definition of compassion: the desire to alleviate suffering. Nothing in the course of human history meets that definition so fully as the achievements of evidence-based, scientifically verifiable medicine. The world of CAM is powered by theories that have almost never been tested successfully, and its proponents frequently cite that fact as proof of their unique value, as if they represent a movement that cannot be confined (or defined) by trivialities.

“I think that there is a tension in this area, and I feel this as a practitioner—that while I’m comfortable in trying to reassure people, I’m not comfortable in fooling them. And you know, I think any physician is aware that some of the confidence you build in someone is part of helping them get better, and when is that being a confidence man? That tension is kind of inherent in healing practices. It’s interesting; it’s not easily solvable.” Briggs has become fascinated with the causes of the placebo effect—how it works on a biochemical level, and why. That the mind can affect the chemistry of the human body is not in doubt, and researchers have shown direct relationships between what a patient expects from a drug and its therapeutic results. In one experiment, Fabrizio Benedetti, professor of clinical and applied physiology at the University of Turin Medical School in Italy, demonstrated that a saline solution works just as well as conventional medicine to reduce tremors and muscle stiffness in people with Parkinson’s disease.

But since they did, they’ll attribute the change to the seminar. In the seminar example you just cited, isn’t it also possible that people will feel and perform better because of the placebo effect? For that matter, isn’t it possible that the results attributed to NLP may also be a placebo effect? Charles Faulkner / 419 In part, this contention may be valid, and it fascinates me that this is supposed to be a criticism. Medical science researchers take the view that the placebo effect is something had. You can hear it in their language: “We have to rule out the placebo effect.” However, Bandler and Grinder looked at it differently. They saw the placebo effect as a natural human ability—the ability of the brain to heal the rest of the body. This actually presents exciting possibilities. What if this ability can be called forth when we want it or need it’?

What if this ability can be called forth when we want it or need it’? What if our brains can literally make us feel better’? NLP is concerned with results. If the favorable results are partially due to the placebo effect—that is, the natural ability of the brain to affect how we feel, heal, and function, mentally and physically—let’s use it deliberately. NLP makes claims of being able to change behaviors and feelings very quickly through simple mental exercises. Can you give me an example of such an exercise in order to give readers who are completely unfamiliar with NLP some flavor of the approach? Let me offer an example that will probably be of use to most of your readers. We’ve all been in trading situations where the market moved dramatically against our position. The question is: How unsettling or disconcerting was it?

However, in 1960, there appeared in the American Journal of Cardiology a remarkable report that shed a completely different light on the reasons why angina sufferers who underwent the surgery experienced decreased pain.26 It seems that a number of surgeons, aware that this particular procedure had never been adequately tested and also aware that angina is notoriously responsive to placebo treatment, had begun to consider the possibility that the patients experienced a decrease in pain only because they believed in the surgery—in other words, that this major operation was, in fact, totally worthless. Doctors have known for centuries of the placebo effect. You can give patients pills specifically designed to be devoid of any conceivable medical efficacy, and some of these patients, because they believe they are receiving substances with genuine medical value, will report improvement. Now doctors were beginning to consider the staggering possibility that the reported benefits from the angina surgery were the result of a placebo effect. How were they to find out? It’s relatively easy to test pills for a placebo effect. You simply do a double-blind study, giving some patients the real thing, others placebos, and see what happens. But it’s not so easy to put surgery to the test.

In this case, however, the doctors were sure enough of their hunch that they did, in fact, eventually perform a number of sham, or placebo, operations. They then reported the results in the American Journal of Cardiology.27 Amazingly, the patients who underwent the sham surgery reported the same degree of angina relief as those undergoing the real surgery! The verdict was unavoidable. The fashionable operation had derived its efficacy entirely from the placebo effect. Surgeons now realized that this operation was no longer ethically justifiable. But they were not so easily to be deprived of a chance to operate on angina sufferers. They conceived an even more intrusive procedure—internal mammary artery implant. This involved poking a hole in the heart muscle, cutting the artery, and then inserting the cut end of the artery into the heart, hoping it would sprout new branches, thus supplementing the coronary arteries and bringing more blood to the heart.

Again, patients who underwent the surgery reported decreases in angina pain after recovering from the surgical trauma, and again the surgeons trumpeted their success. No one ever put this procedure to the test of comparison with sham surgery. However, autopsies later done on patients who received this surgery showed that the implanted arteries had not sprouted new branches or provided any new blood supplies to the heart, as had been hoped. In short, any success this massive intervention had was due, again, to the placebo effect. So great had been the faith of the patients in surgery as a healing modality, that even though they underwent traumatic surgery that was, in fact, physically worthless, many of them reported symptomatic relief. It seems we haven’t even begun to scratch the surface of understanding how profound and powerful a thing faith is. Is it any wonder, then, given the faith we have all been continuously programmed to have in meat, that some people report they feel better when meat is part of their diet?

It could just as easily be due to the reduction in calories or the addition of carbohydrates or polyunsaturated fats. For every diet hypothesis you test, you can construct an alternative hypothesis based on the presence or absence of the substitute nutrient. It gets messy. And then there is the placebo effect, which has always bedeviled nutrition research. About a third of Americans are what researchers call responders—people who will respond to a treatment or intervention regardless of whether they’ve actually received it. When testing a drug you can correct for this by using a placebo in your trial, but how do you correct for the placebo effect in the case of a dietary trial? You can’t: Low-fat foods seldom taste like the real thing, and no person is ever going to confuse a meat entrée for a vegetarian substitute. Marion Nestle also cautions against taking the diet out of the context of the lifestyle, a particular hazard when comparing the diets of different populations.

Once you’ve read this chapter, I want you to feel that your accelerator and your brakes are as basic, as integral to your sexual functioning, as your clitoris and your desire. If I do my job in the next few pages, you’ll be telling everyone you know: “OMG, everybody, there’s a brake!” The Power of Context Erectile dysfunction drugs don’t improve women’s sexual functioning, but they do have one of the strongest placebo effects observed in medical research. Around 40 percent of participants in the placebo group of a clinical trial of sexual dysfunction medication report that the “drug”—actually a sugar pill—improved their sex lives; this is a response size so large that one particularly brilliant study reported only the effects of an eight-week “treatment” with a placebo.2 This is just one small hint at the power of context in shaping our sexual experience, which we’ll discuss in chapter 3.

Something particularly interesting about the study of brain functioning in people with chronic back pain: When they directed their attention to the burning sensation on the skin of their back, they reported that the heat hurt; when they directed their attention to the pain in the muscles of their back, they reported that the heat felt good. Where we focus our attention is part of context. The NAc even appears to be important in placebo studies (Zubieta and Stohler, “Neurobiological Mechanisms of Placebo Responses; Tracey, “Getting the Pain You Expect”). Remember the placebo effect from chapter 2—about 40 percent of people taking a sugar pill that they are told will increase their interest in sex, do indeed experience more interest in sex. I expect that future research will find that the nucleus accumbens is involved in that effect. 15. Berridge and Kringelbach, “Neuroscience of Affect,” 295. 16.

After I found that flaxseed oil improved balance, I used self-experimentation to figure out the best dose (three to four tablespoons per day). One complaint about self-experimentation is that you’re not “blind.” Maybe the treatment works because you expect it to work. A placebo effect. I have never seen a case where this appeared to have happened. When treatment 10 helps after treatments 1 through 9 have failed to help (my usual experience), it’s unlikely to be a placebo effect. Accidental discoveries cannot be placebo effects. My experience has shown that improve-your-life self-experimentation is remarkably powerful. I wasn’t an expert in anything I studied—I’m not a sleep expert, for example—but I repeatedly found useful cause-and-effect relationships (breakfast causes early awakening, flaxseed oil improves balance, etc.) that the experts had missed.

I found this particularly bothersome. Bothersome because I appeared to heal faster using oral 30C arnica. There are a few potential explanations: HOMEOPATHIC REMEDIES WORK AS ADVERTISED The water actually retains some “essential property” of the original substance because of the beatings and shakings. I give this a 0% probability. It violates the most basic laws of science and makes my head hurt. THE PLACEBO EFFECT I didn’t realize it was a homeopathic remedy until after four or five doses, and I had been told it could reduce pain by up to 50% in 24 hours. Placebo is strong stuff. People can become intoxicated from alcohol placebos, and “placebo” knee surgeries for osteoarthritis, where incisions are made but nothing is repaired, can produce results that rival the real deal. This explanation gets my vote.

In the pharmaceutical industry, the gold standard of drug development is the so-called double-blind placebo-controlled trial. Volunteers are randomly assigned to receive either the active drug or an inert placebo, and neither the volunteers nor the experimenters are aware of who is getting the real drug and who is getting the equivalent of sugar pills. Inevitably, both groups of patients will show some improvement because of a phenomenon known as the placebo effect. At the root of the placebo effect is the fact that the attention of medical professionals, in an environment of care, produces beneficial changes in the mind and body of the patient even in the absence of an active drug. Researchers like Ted Kaptchuk at Harvard and Fabrizio Benedetti at the University of Milan have discovered that the mere act of swallowing a pill triggers cascades of hormones and neurotransmitters that can reduce pain and inflammation, enhance motor coordination, boost brain activity, lift mood, and improve digestion.

Researchers like Ted Kaptchuk at Harvard and Fabrizio Benedetti at the University of Milan have discovered that the mere act of swallowing a pill triggers cascades of hormones and neurotransmitters that can reduce pain and inflammation, enhance motor coordination, boost brain activity, lift mood, and improve digestion. These effects are pervasive, as if the body contains a self-healing network that is activated by the knowledge that one is receiving care. (Exercise and meditation also prompt this network into action.) While no one has ever cured cancer or dispelled pneumonia with a sugar pill, powerful placebo effects have been observed in an astonishingly broad range of conditions, from Parkinson’s and hypertension to chronic depression and Crohn’s disease. In placebo-controlled trials, if the volunteers in the placebo group and the experimental group show comparable amounts of benefit, the FDA judges the drug to be ineffective—often at the cost of tens of millions of dollars to the company that spent years developing it.

A Navy statistician with access to the raw data concluded that no reliable information about the reaction to the vitamins by various subtypes in the sample population could be obtained by using Rimland’s computer-clustering scheme. Furthermore, the design of the experiment—with parents as evaluators of changes in their children’s behavior—was anything but “blind” in the statistical sense, and a perfect incubator for placebo effects. Rimland knew that accurately gauging the efficacy of new treatments for autism is tricky because the condition is so mercurial. “These children spurt ahead or fall apart periodically for no discernible reason,” he said, “and whatever treatment is being used at the time gets the credit or the blame.” Yet even Rimland was not immune to the pitfalls of wishful thinking. A thinly veiled account of his experiments with Deaner appeared in his book, referencing an unnamed “four-year-old autistic child who unquestionably belonged to the Kanner category.”

A buzzword these days for unnecessary or ineffective medical procedures or care is “low value.”33,35–39 A recent example is arthroscopic (performed via a scope to limit the size of incision) knee surgery known as “partial meniscectomy”—the most common operation in the United States, with over seven hundred thousand performed each year with direct medical costs of $4 billion.40 In a randomized trial conducted by Canadian researchers, patients with a torn meniscus were randomized to arthroscopic partial meniscectomy or a sham operation, such that the patient or researchers collecting the data for the patients did not know which had been performed.40 There was no difference in outcomes, emphasizing the profound placebo effect of surgery itself. What makes the trial truly notable is the rarity of such experimental rigor in testing surgeries. Although using sham controls for comparison with actual procedures is the best way to distinguish the placebo effect, surgeons and patients are typically quite reluctant to participate in such a trial design. For this reason, there may well be many operations and procedures that are ineffective, but there have not been any rigorous trials putting them to the test. FIGURE 8.2: Sources of waste of US health care dollars.

Let’s consider a patient with depression, a condition for which mobile apps are already starting to make a difference.95b A medication has been prescribed and there is a question as to whether it is working. The patient reports feeling subjectively better, but all of the objective indices—tone and inflection of voice, frequency of communication, activity and movement, breathing pattern, facial expression, vital signs, HRV and GSR—show no sign of improvement whatsoever. Does this diagnose a placebo effect of the medication? The patient looks at the integrated data and notes a dissociation of symptoms and the metrics. A whole new discussion can ensue as to whether a medication is necessary, whether it’s really working, and the potential to explore other alternative nonmedical treatments. Or another patient with a history of frequent asthma attacks is now using the lung smartphone add-appter, which gathers environmental exposures that include pollen count and air quality, ambient temperature and humidity, along with activity, vital signs, lung function (forced expiratory volume in one second via the microphone), chest movement, and breathing pattern.

In two of them, the consent form contained a statement outlining various gastrointestinal side effects, and in these centres there was a sixfold increase in the number of people reporting such symptoms, and many more people dropping out of the trial, compared with the one centre that did not list such side effects on the form. This is the amazing world of the nocebo effect, the evil twin of the placebo effect, where negative expectations can induce unpleasant symptoms in the absence of a physical cause. Sadly, though, it doesn’t help homeopaths: in 2003 Professor Edzard Ernst conducted a systematic review of every single homeopathy trial that reported side effects. This found, in total, fifty episodes of side effects in patients treated with placebo and sixty-three in patients treated with homeopathically diluted remedies, with no statistically significant difference in the rates of side effects between the two groups. Quacks like to present themselves as holistic, but in reality this research into the placebo effect and the nocebo effect suggests quite the opposite. The world of the homeopath is reductionist, one-dimensional, and built on the power of the pill: it cannot accommodate the fascinating reality of connections between mind and body, which have been revealed in these experiments, and many more.

When they pervert the activities of people who should know better – medicines regulators, or universities – it throws sharp relief onto the role of science and evidence in culture. Characters from this community who wonder why people keep writing about them should look at their libel cases and their awesomely bad behaviour under fire. You are a comedy factory. Don’t go changing. Next: the real story of how the world works is much weirder than anything a quack can make up. The placebo effect is maddening, the nocebo effect more so, but the research on how we make decisions, and are misled by heuristics and mental shortcuts, is the wildest of all. Knowing about these belief-hacks gives you thrills, and power. Pharmaceutical companies can behave dismally. Most important, they still won’t publish all the results of all the clinical trials conducted on humans. This is indefensible, and because we tolerate it, we don’t know the true effect sizes of the medicines that we give.

But when it comes to medical care, things are never equal, and I prefer Hahn over docs who take at face value what they read in the health section of the local newspaper. “What we think we know about nutrition is not supported by real scientific inquiry,” he told me on a subsequent occasion. Little biological evidence exists, he said, to support the claims of those who caution against particular foods. If some people are healthier for having eschewed those foods, the reason may well be psychological. “Because of the placebo effect, people feel better when they adopt certain dietary habits,” Hahn contended. When I reminded him that his views are at odds with what one hears from physicians at the American Heart Association and diet advisory panels of the U.S. government, he recommended I do a small study myself to see how much those docs are really willing to attribute to diet.41 False Prophets 25 “You have to ask the right question,” said Hahn.

The pitch for Glacéau Revive differs from what McDonald’s used to do for its supersized fries only in audience. Both companies have implored people to pay extra for something they can do without. The McDonald’s customer at least got what was promised. The functional-foods consumer gets only a promise. People who feel more mentally adept after drinking fortified water are probably responding 46 The Gospel of Food either to the sugar in the product or to the placebo effect (having been told they will feel revived, they do). Even in the case of products whose additives have a legitimate scientific basis, the promised benefits can prove illusory. Gold Circle Farms promises better vision, brain function, and cardiovascular health to those who buy its eggs enriched with DHA omega-3, a fatty acid that research has found to be beneficial for protecting against a range of diseases.

Moved by any number of unacknowledged biases, they are easy prey to manipulative devices deployed by those who want to sell them things. Prices help us understand these cognitive lacunae. They provide a road map of people’s psychological quirks, of their fears, their unacknowledged constraints. Prices—how they are set, how people react to them—can tell us who people really are. Most of us have heard of the placebo effect—in which a pill with no therapeutic properties relieves a real ailment by making us believe that we are being cured, setting in motion some inner psychological process. A few years ago, psychologist Dan Ariely from the Massachusetts Institute of Technology and some colleagues performed an experiment that uncovered an interesting variant. They told a bunch of students they were getting a new type of painkiller but gave them a placebo instead.

During treatment, the acupuncturist also interacts with the patient in a physically attenuated way— holding the patient’s hand gently as he or she studies the patient’s pulse for a full minute or two, carefully placing each needle (or even sham needle), taking the pulse again after the needles come out and seeing what’s changed. These interpersonal interactions with a healing practitioner may in and of themselves be enough to stimulate or enhance the placebo effect to the extent that pain, anxiety, and other symptoms are, at least temporarily, blunted. I think of something I recently read—almost humorous—that simply running your fingers over money relieves chronic pain. Having a practitioner place so much emotional and physical attention on you, your story, and well-being may be a bit like smoothing your hand over a million-dollar bill. Indeed, MRIs of patients’ brains show that real acupuncture does something quite extraordinary to the placebo effect itself: placement of needles in key meridians directly stimulates the area in our brain that governs our placebo response, or the expectation of a good, pain-free outcome.

We will focus on the basic approaches of meditation, yoga, and acupuncture, for three reasons. First, these modalities are available to most people no matter where they live. Second, meditation and yoga have been shown to be beneficial in terms of lowering inflammatory markers linked to virtually every disease from depression to back pain to cancer. The research on acupuncture is still emerging, with some scientists arguing that its benefits may be due in part to the placebo effect—and yet, real or placebo, people heal. Rowland-Seymour sees acupuncture transform her patients’ lives. And finally, meditation and yoga can be learned without great expense through affordable community classes and supplemented with Internet downloads or DVDs. Acupuncture is usually covered by insurance. 3. I will spend a year working with experts who have trained in one of the above modalities and used them for healing in their own lives. 4.

We looked for (and did not find) differences in the capabilities or motivation of LU and non-LU project team members with respect to achieving a major new product advance. 3M managers also said that there was no difference in these matters, and a content analysis of formal annual performance goals set for the individual LU and non-LU team members in a division that allowed access to these data supported their views. We also found no major differences in the innovation opportunities teams faced. They also looked for Hawthorne or placebo effects that might 138 Chapter 10 affect the project teams differentially, and found none. (The Hawthorne effect can be described as “I do better because extra attention is being paid to me or to my performance.” The placebo effect can be described as “I expect this process will work and will strive to get the results I have been told are likely.”) We concluded that the 3M samples of funded LU and non-LU idea-generation projects, though not satisfying the random assignment criterion for experimental design, appeared to satisfy rough equivalence criteria in test and control conditions associated with natural or quasi-experimentation.

For people living in countries that have more recently experienced rip-roaring inflation or currency crises, this relativity is easier to grasp. One week 10,000 pesos pays the rent, the next week it can’t buy a tank of gas. The money illusion in the modern age can have a bizarre influence on our decisions. Because we have a built-in bias for bigger numbers, we presume that the higher-priced wine, automobile, restaurant, college, or hotel will offer better quality, better value. Economists have even shown that the placebo effect of a pretend medication (vitamin C pills, for instance) is stronger when the price of the “drug” is higher.18 The money illusion also helps to explain why we value a $100 gift card or check as less than an equivalent amount of cash, which is to say we are more apt to spend it. The artifice with gift cards is that they have no value, so we act as if they’re play money. To economists, a restaurant coupon worth $100 equals $100 in cash, equals $100 in a bank account.

But as of this writing, anyone who first suggests to you that T3 should be routinely added to your T4 or other medications you might be taking or used as a solo therapy is not up to date. In the peer-reviewed literature, there is some discussion of whether a long-acting T3 therapy could be developed. Additionally, there is recognition that there is a subset of patients who simply feel better on T3/T4 for reasons we don’t yet understand. Many attribute this to a placebo effect, which is a real physiological effect where an individual’s strong belief in a medication or therapy produces endorphins in the brain that actually help the individual feel better. Why Do I Still Feel Hypothyroid? If you have normal TSH levels but still have symptoms of hypothyroidism, then you will be relieved to know that the symptoms that persist are not likely to be related to your hypothyroidism and you can, at last, investigate other causes and remedies.

Biochemically, if you give people with normal thyroid function T3 when they don’t need it, they will become thyrotoxic (see Chapter 4). Also, even if we assume these testimonials are real, they fail to account for two well-known facts. First, a lot of people will just get better on their own because these symptoms tend to resolve once certain stressors are removed—even in people who have symptoms for months at a time. And second, the placebo effect (the power to heal yourself based solely on the belief that you’re taking effective medicine) often makes people feel better, as discussed further on. “My Obesity Is Caused by Hypothyroidism, Even Though My TSH Levels Are Normal” How many euthyroid people are obese? Millions! Why is that? Because they eat more food than they burn off in activity. We are a sedentary society that is aging and out of shape.

If you are hypothyroid and depressed, then T4 will do the same job on your depressed brain as taking T3, but its beneficial effects will be more long-lasting, yet not as immediate, since T4 has a longer half-life. When you give depressed people a placebo and tell them it is T3, assuring them that it will lift depression, at least half of those people will report an improvement because of the placebo effect, which is a real pharmacologic effect caused by our natural endorphins and the power of our beliefs. In fact, several medical ethics articles point out that clinical control trials using placebos are actually testing two types of “drugs,” since placebo is not the same as “nothing.” 262 THYROI D M ISCONCEPTIONS AN D M ISI N FOR M ATION Misconceptions About Radioactive Iodine (RAI) Radioactive iodine (RAI) is used for thyroid scans (see Chapter 2) as well as therapy for Graves’ disease and thyroid cancer (see Chapter 12).

From their perspective this was ‘a wonderful drug’, they explained, ‘light-years better than previous treatment’. It ‘began to eliminate cancer symptoms in seven days’. Tumours were ‘90 per cent gone in three months’, said one. Whether that was exaggeration or fluke, the reality is that fair tests showed no benefit. But the desperate patients disagreed, and asserted their case plainly and simply: Iressa ‘will save lives’. This personal testimony was in all likelihood a combination of the placebo effect and the natural fluctuation in symptoms that all patients experience. That didn’t seem to matter. When the committee charged with approving the drug cast their votes, they went 11–3 in favour. It’s hard to know what to make of this process, since the vote went against not only the surrogate outcome data, but also the evidence from very large trials showing no benefit on real-world outcomes or survival.

These simple trials have one disadvantage, which you may already have spotted, in that they aren’t ‘blinded’, so the patients know the name of the drug they’ve received. This is a problem in some studies: if you believe that you’ve been given a very effective medicine, or that you’ve been given a rubbish one, then the power of your beliefs and expectations can affect your health, through a phenomenon known as the placebo effect. If you’re comparing a painkiller against a dummy sugar pill, then a patient who knows they’ve been given a sugar pill for pain is likely to be annoyed and in more pain. But it’s harder to believe that patients have firm beliefs about the relative benefits of atorvastatin and simvastatin, and that these beliefs will then impact on cardiovascular mortality five years later. In all research, we make a trade-off between what is ideal and what is practical, giving careful consideration to the impact that any methodological shortcomings will have on a study’s results.

The FDA saw this coming a long way off, so it declined to license the product at all, specifically citing concerns about off-label use after the approval committee’s unanimous ‘no’ vote.33 This might be a good moment to mention that the evidence for testosterone patches being any use, even after surgery, is extremely weak, from two trials in very unrepresentative ‘ideal patients’, showing marginal benefits against a massive placebo effect, with common side effects (sometimes apparently irreversible), and no long-term safety data.34 It’s worth noting that almost no treatments for FSD have come to market, and crucially, all of the disease-mongering activity we have seen happened in the lead-up to their approval. This was simply the academic groundwork in the companies’ ‘publication planning’ programme, where they prove that a problem is widespread, and create a desire for a cure.

Just looking at the table, you can see that a cold is twice as likely to develop if you take echinacea as not (the right column of the table). To put this into Bayesian form, the probability of getting a cold, given that you took echinacea, still equals .67. By the way, the placebo effect—that we feel better and often get better just from taking something, even if it has no medicinal ingredients—is very real and very strong. Larger pills have a bigger placebo effect than small pills. Sham injections have a larger effect than pills. A great deal of the effect of products with no known medicinal value may simply be this placebo effect. This is why double-blind, randomized clinical control trials are necessary: Everyone in the study gets a pill and nobody knows who got what. Many of the people taking the “empty” pill are going to improve relative to people who got nothing, but if the medicine really works, it should work even better than placebo.

The World of Caffeine: The Science and Culture of the World's Most Popular Drug by Bennett Alan Weinberg, Bonnie K. Bealer

In the twentieth century, medical studies have credibly linked caffeine to causing or aggravating PMS, lowering rates of suicide and cirrhosis, fostering more efficient use of glycogen and other energy sources such as body fat and blood sugars, improving performance of simple tasks, impairing short-term memory, potentiating analgesics, improving athletic performance, causing insomnia, alleviating migraine headaches, depressing appetite, relieving asthma, and so on. There remains considerable ambiguity about many of these putative effects. For example, some researchers have found that caffeine improves mood and performance only when people are aware that they have consumed it, which if true would mean that even the most widely acknowledged results of taking the drug are simply placebo effects! However, if you have any doubt that caffeine is a drug, and a potent one, consider that a dose of only 1 gram, equivalent to about six strong cups of coffee, may produce insomnia, restlessness, ringing in the ears, confusion, tremors, irregular heartbeat, fever, photophobia, vomiting, and diarrhea. Severe intoxication may also cause nausea, convulsions, and gastrointestinal hemorrhage. The lethal dose for a two-hundred-pound adult is estimated at about 10 to 15 grams.

He concluded that it was impossible to flunk the IOC test as a result of the ordinary consumption of caffeinated beverages and that any athlete who failed to pass should be presumed to have resorted to caffeine to enhance his performance.85 Although a number of athletes have run into trouble over their urinary levels of caffeine, so far the IOC itself has disqualified only one participant on this account, an Australian pentathlon competitor in the Seoul Olympics in l988.86 Interest in caffeine’s benefits to exercise increased in the late 1970s after studies from the Human Performance Laboratory at Ball State University suggested that 200 mg of caffeine exerted a significant effect on an athlete’s endurance. Other studies have failed to confirm this conclusion, and some have suggested that the observed improvements were a consequence of a placebo effect. Determining the answer comes down to evaluating whether caffeine has ergogenic effects—that is, whether it can improve aerobic performance or the capacity of the body for physical work. The body gets the energy needed to power muscles in at least three different ways, depending on whether the energy expenditure is of short, moderate, or extended duration. Energy is also burned differently by muscles of different sizes.

In some individuals, therefore, heavy use of caffeine apparently provokes sleepiness. This is difficult to explain since caffeine is a stimulant.... The unusual magnitude of the sleepiness and the rarity of this apparent association between caffeine and excessive sleepiness, even in sleep clinic patients, suggest an idiosyncratic phenomenon.32 Another strange effect, which might be called the “reverse placebo” effect, was observed by A.Goldstein in a 1964 study. Participants in his experiment were all given caffeine. Those who knew they had taken the drug were less likely to complain of wakefulness than those who were not informed whether they had taken caffeine or a placebo.33 Perhaps this could also be called the “bravado effect,” whereby people are reluctant to confess a disturbance from what is ordinarily considered a mild agent, such as caffeine.

If the pills cannot pass this test – if numerous strenuous efforts fail to distinguish them from a neutral placebo – I presume the company might be in danger of prosecution under the Trades Descriptions Act. Homeopathic remedies are big business, they are advertised as efficacious in various ways, yet they have never been demonstrated to have any effect at all. Personal testimony is ubiquitous, but it is useless evidence because of the notorious power of the placebo effect. This is exactly why ‘orthodox’ medicines are obliged to prove themselves in double-blind trials.8 I do not want to imply that all so-called ‘alternative medicines’ are as useless as homeopathy. For all I know, some of them may work. But they must be demonstrated to work, by double-blind placebo-control trials or some equivalent experimental design. And if they pass that test, there is then no longer any reason to call them ‘alternative’.

The randomizing will be done by computer, in such a way that nobody will know which patients are experimentals and which controls. The patients themselves won’t know; the therapists won’t know; the pharmacists preparing the doses won’t know, and the doctors judging the results won’t know. The bottles of medicine will be identified only by impenetrable code numbers. This is vitally important because nobody denies placebo effects: patients who think they are getting an effective cure feel better than patients who think the opposite. Each patient will be examined by a team of doctors and homeopaths, both before and after the treatment. The team will write down their judgement for each patient: has this patient got better, stayed the same, or got worse? Only when these verdicts have all been written down and sealed will the randomizing codes in the computer be broken.

Spectator sports are excellent, so are circuses, elec- tions, and any spectacles in which focus is outward and interpersonal exchange is subordinated to mass experience. 4) Unify experience, especially encouraging mental ex- perience at the expense of sensory experience. Separate people's minds from their bodies, as in sense-deprivation experiments, thus clearing the mental channel for implanta- tion. Idealize the mind. Sensory experience cannot be eli- minated totally, so it should be driven into narrow areas. An emphasis on sex as opposed to sense may be useful because it is powerful enough to pass for the whole thing and it has a placebo effect. S) Occupy the mind. Once people are isolated in their minds, fill the brain with prearranged experience and thought. Content is less important than the fact of the mind being filled. Free-roaming thought is to be discouraged at all costs, because it is difficult to control. 6) Encourage drug use. Recognize that total repression is impossible and so expressions of revolt must be con- tained on the personal level.

The cancers may be imagined in the form of animals, snakes, armies, non-objective force-fields, whatever seems to have meaning in a particular patient." The Simontons also use photos of cells, photos of cancers, X ray photos of the person's own cancer to aid the process of imaging and at some point they ask patients to visualize themselves totally well. Critics of the Simontons' success statistics like to argue that it is not the visualizations themselves which have produced the results, but rather the belief in them, the placebo effect. But, of course, this is an absurd criticism, because the belief in the cure is itself likely to come in the form of a visualization of the healthy body. In either event, it is the image that effects the cure. The Samuelses' book is an amazing and fascinating work. They quote from virtually every religious discipline, every healing system in the history of the world about which any evidence exists.

First of all, there’s a large body of evidence to suggest that belief in a cure makes a cure more likely, and more successful. Pharmaceutical researchers grapple with this issue all the time, as the success rate of placebos and real pills is often surprisingly similar. A few years ago researchers dismissed the placebo response as imaginary and of no medical value. Yet recent studies have shown the opposite: not only can the placebo effect deliver real lasting benefits, but the belief that something is making us sicker can actually lead to real deterioration, even death. Saying “It’s all in your mind” used to be a way to dismiss unexpected effects, but all of psychiatry is in the mind, so that dismissal is not so relevant when it comes to how we feel. It’s possible that some of us went into the TMS study believing in its power while others were largely neutral and we were now having different experiences as a result.

I couldn’t talk to the other participants to learn how they felt. Might something similar have happened in the depression studies I read about? When treating a disorder of the mind, “believing it’s so” might well be tantamount to “making it so,” in a way that’s dramatically different from treating chronic disease elsewhere in the body. There was also another important difference when comparing the placebo effect in TMS and medications. In drug therapy, a placebo pill is truly inert. It’s flour, or sugar, something we know does not have curative properties. That’s not the case with sham TMS. Scientists create sham TMS in many ways, including by firing the TMS coil into space beside your head, firing it at a different area of your head, or firing it at a low power level. The thing is, all those sham actions still have the potential for neurological effect.

When Miss Lunsford, a nutritionist and graduate student at Cornell University working in the lab of biochemist and gerontologist Clive McCay, shared these results at a gathering to focus on the problems of aging led by the New York Academy of Medicine, no one—not even Lunsford and her teammates—could explain this “age-reversal” transformation. The year was 1955, the same year the Food and Drug Administration approved the polio vaccine, the power of the placebo effect was first written about, Albert Einstein died at the age of seventy-six, and Steve Jobs and Bill Gates were born.2 Miss Lunsford’s procedure, anatomically linking two organisms, had a name by then—parabiosis. But while this wasn’t the first time it had been performed, her explorations were among the first to use parabiosis to study aging. And they weren’t without their challenges. According to one description of the research, “If two rats are not adjusted to each other, one will chew the head of the other until it is destroyed.”3 Of the sixty-nine pairs of rats that Lunsford had helped conjoin in Clive McCay’s lab, eleven died from a peculiar condition that developed about one to two weeks after partners were united; it was likely a form of tissue rejection.

In the words of Gibson: “In contrast to our first study . . . we could find absolutely no specific response to gluten.”8 Although this was also a small study, another larger one published later on confirmed the findings. How do we explain this unexpected result? This is where the science gets interesting. It could be that people expected to feel worse on the study’s diets, so they did—a phenomenon called the “nocebo” effect, a wordplay on the placebo effect. After all, they did have to pay close attention to how their tummies felt, which alone might entail some psychosomatic response. Moreover, it’s been suggested that gluten may be the wrong villain and that these other potential triggers, especially the FODMAPs, are to blame. These ingredients often travel with gluten. It may in fact be the carbohydrate component rather than the gluten part of the wheat that is causing symptoms.

Whether or not we have faith in our health has everything to do with whether or not we have a healthy body. If we believe we can be healthier, guess what: we will be. Some of the most dramatic experiments putting this idea to the test are those in which people unknowingly receive fake (placebo) treatments for real health problems and come out reporting that they have improved just as much as those who got the real treatment. The placebo effect is all about a positive belief system. On the other side of the equation are stories that reveal the power of a negative belief system, one of which was famously documented in 1974 when Sam Londe was diagnosed with esophageal cancer. At the time such a diagnosis was a death sentence, so no one was surprised when he died a few weeks later, despite treatment. But what shocked the medical community was the discovery upon autopsy that Sam didn’t have esophageal cancer at all.

Probability is next to truth, and the search of a hidden cause finds out visible effects.26 Of course reliability is a slippery concept. We only need to turn to the doctors of Montaigne’s day for a cautionary example. They thought they were using their knowledge to cure patients. In fact, their preferred remedies (bleedings and purges) did no good at all.27 They mistook the patients’ spontaneous recovery (thanks to the workings of their immune systems), combined with the placebo effect, for cures brought about by medical therapy (and intelligent bystanders such as Montaigne suspected as much).v In medicine there were no reliable methods of measuring success until the nineteenth century. But the Ptolemaic astronomers of Montaigne’s day were very different from the Hippocratic doctors. Clavius claimed that eccentrics and epicycles must exist, otherwise the success of the predictions made by astronomers were inexplicable: But by the assumption of eccentric and epicyclic circles not only are all the appearances already known preserved, but also future phenomena are predicted, the time of which is altogether unknown. . . . it is not credible that we should force the heavens (but we seem to force them, if eccentrics and epicycles are fictions, as our adversaries would have it) to obey our fictions and to move as we wish or as agrees with our principles .28 Clavius was wrong – there are no eccentrics and epicycles – but he was right to claim that he could predict the future movements of the heavenly bodies with a high degree of reliability.

While the women were under the spell of sad memories, these receptors were much less active.6 On the other hand, positive expectations turn on the endorphin system. Scientists have observed, for example, that when people expect relief from pain, the activity of opioid receptors will increase. Even the administration of inert medications—substances that do not have direct physical activity—will light up opioid receptors, leading to decreased pain perception.7 This is the so-called “placebo effect,” which, far from being imaginary, is a genuine physiological event. The medication may be inert, but the brain is soothed by its own painkillers, the endorphins. Opiate receptors can be found throughout the body and in each organ they play a specific role. In the nervous system they are tranquilizers and painkillers, but in, say, the gut, their role is to slow down muscle contractions. In the mouth, they diminish secretions.

The banks championing the new standard discovered that the cost was horrendous. It was too late to back out. Fischer Black, one of the creators of the Black–Scholes–Merton model, did not like false degrees of precision, too many decimal points were misleading when the information was inexact. Risk managers and modellers largely ignore this. Spreadsheets with floating 16 decimal points provide false comfort in the perfect storm. Risk is itself a risky business. Placebo effects Risk management abounds in myths, for example the 4:15 Report. The title refers to the time in New York at which the chairman of JP Morgan received a daily report summarizing the bank’s risk. The idea was that the entire bank’s risk was reduced to this simple number; the popular mythology was that you pressed a button and out popped the report, but the reality was probably less glamorous. Someone in risk painstakingly pulled data from a myriad of systems of varying degrees of accuracy and reliability and collated them on a spreadsheet.

“By contrast, the views expressed in the paper are unambiguously clear: ‘we did not prove an association between measles, mumps, and rubella vaccine and the syndrome described.’ ” 26 There are several ways to conduct randomized trials. The ideal one is through a double blind test, in which neither the researcher nor the test subjects know who is being studied and who is a control. Double blind trials protect against the placebo effect on the part of the subject and observer bias (or wishful thinking) on the part of the researcher. 27 A real-world example of a theory proven to be true after all three types of studies were performed is the beneficial effects of fluoridation. First was the case series: A dentist noticed that patients with mottled teeth seemed to have less tooth decay. Next was the case control study: Children who’d spent their whole lives in an area with naturally fluoridated water were compared to those who’d moved there after their teeth had fully developed.

An indiscriminate attitude toward treatment also makes it hard to determine what changes are due to the natural rhythms of disease: Temporary ailments by definition get better and the symptoms of lifelong conditions almost always wax and wane, which means that even the most far-fetched cure is bound to look like a winner every now and again. In his book Innumeracy, the mathematician John Allen Paulos describes how proponents of pseudoscientific therapies rely on this reality to shade their products in the best light possible. “To take advantage of the natural ups and downs of any disease (as well as of any placebo effect),” Paulos writes, “it’s best to begin your worthless treatment when the patient is getting worse. In this way, anything that happens can more easily be attributed to your wonderful and probably expensive intervention. If the patient improves, you take credit; if he remains stable, your treatment stopped his downward course. On the other hand, if the patient worsens, the dosage or intensity of the treatment was not great enough; if he dies, he delayed too long in coming to you.”

10% Human: How Your Body's Microbes Hold the Key to Health and Happiness by Alanna Collen

In a French clinical trial, fifty-five normal, healthy volunteers – humans this time – were given either a fruity-tasting bar containing two strains of live bacteria, or a matching bar but without the bacteria (a placebo). After a month of eating one bar daily, the volunteers given the live bacteria scored happier, less anxious and less angry than they had been before the trial – and the changes went beyond the placebo effect. As trials go, it’s short and small, but it offers a glimpse of research avenues worth exploring. How can eating live bacteria make you feel happier? Pleasingly, one potential mechanism seems to have to do with a chemical that’s well known to be involved in mood regulation: serotonin. This neurotransmitter is actually mainly found in the gut, where it keeps everything moving along nicely. But around 10 per cent of serotonin belongs in the brain, regulating mood and even memory.

The butyrate-producing team of Faecalibacterium and Bifidobacterium, too, were far more numerous after my dietary intervention than before. I like to think of them helping the cells of my gut lining stay tightly knit together and calming my immune system. So far, so satisfying, but what about its impact on my health? It feels as if things are improving – my fatigue has eased off and my rashes have cleared up, for now at least. Time will tell whether that’s luck, the placebo effect, or a genuine result of eating more fibre, but it’s not something I’ll be giving up. The changes to my microbiota after dabbling in a high-fibre diet are not permanent, of course; to sustain the microbes they feed indefinitely, I have to keep the fibre content of my meals up where it belongs. Eating for a beneficial microbiota has a pertinence for me beyond my own health. As I contemplate embarking on motherhood, it strikes me that I have more reasons than ever to look after all my cells, both human and microbial.

He extracted fluid from the testicles of freshly killed dogs and guinea pigs and injected it into his own body. Almost instantly, he reported, he felt like a new man. The scientist reported that the injections invigorated him, sharpened his intellect, relieved his constipation, and even increased the strength of his urine flow. Scientists today believe Brown-Séquard was the beneficiary of a placebo effect, but his experiment nevertheless gained wide attention and inspired other researchers to explore the secretions of internal organs. By 1905, scientists were learning about the body’s endocrine glands, which include the pituitary gland, thyroid gland, pineal gland, parathyroid glands, thymus, pancreas, testicles, ovaries, and adrenal glands. The glands are small capsules of tissue. The biggest of the bunch, the pancreas, weighs less than three ounces.

The assistant “magnetized” a tree to see whether a blindfolded twelve-year-old could tell it from the other trees. He could not. There was no basis for animal magnetism, the commission reported back. The whole thing was a sham—at least from a scientific standpoint. From what standpoint was it not? If it was all a con, how had it had physical effects on so many people? Mesmerism is one of the earliest examples of the power of our beliefs to change reality: the placebo effect, or dissonance reduction at its finest, in full action. We want to believe something works, and so we will it to work. Our mind literally changes the reality of our body’s health. Mesmer clearly possessed strong powers of suggestion, and people really did get better in his presence. Scientifically, what he was doing was worthless. But people latched on to his purported claims, and the more popular were his successes, the more they conveniently forgot those patients he wasn’t able to help.

homage (HOM-ij), noun Respect paid and deference shown to a superior or other person one admires, fears, or wishes to emulate or praise. Gary took black and white photos with a non-digital camera in HOMAGE to Ansel Adams, whose works he greatly admired. homeopathy (HOME-ee-oh-path-ee), noun The medical practice of giving patients minerals, metals, herbs, and other bioactive compounds in extremely diluted form. Most modern scientists believe the effectiveness of HOMEOPATHY in some cases is due mainly to the placebo effect. homeostatis (ho-me-oh-STAY-sis), noun A dynamic system in which balance between input and output has been achieved, so no net changes take place. When HOMEOSTATIS is achieved in a sealed biosphere, the animals and plants can live without outside air, food, or water. homogenous (ho-mo-JEAN-yus), adjective Consistent in composition or uniform in structure. “By the mere act of watching television, a heterogeneous society could engage in a purely HOMOGENEOUS activity.” – William J.

The Life-Changing Magic of Tidying Up: The Japanese Art of Decluttering and Organizing by Marie Kondo


complexity theory, placebo effect

It is a silent ritual that only takes about two minutes, but it does elicit some strange looks from my clients. I began this custom quite naturally based on the etiquette of worshipping at Shinto shrines. I don’t remember exactly when I started doing it, but I believe I was inspired to do so because the tense expectancy in the air when a client opens the door resembles the atmosphere when one passes under a shrine gate and enters the sacred precincts. You may think that this ritual could only have a placebo effect, but I have noticed a real difference in the speed with which tidying occurs when I perform it. Incidentally, I don’t wear sweats or work clothes when I tidy. Instead, I usually wear a dress and blazer. Although occasionally I don an apron, my priority is on design over practicality. Some clients are surprised and worry that I might ruin my clothes, but I have no trouble moving furniture, climbing onto kitchen counters, and doing the other active work involved in tidying while dressed up.

My Journey as a Combat Medic: From Desert Storm to Operation Enduring Freedom by Patrick Thibeault


affirmative action, placebo effect

I saw a plaque outside this small hospital that recognized several European countries that helped modernize it. There was an airstrip right outside the town that could easily handle a C-130 cargo plane landing. This was important in case we had to call in a medical evacuation request. We stayed in an enclosed area that belonged to the Afghan government, sleeping in the same large room with the Afghan Army soldiers. Some of those soldiers knew that I was a medical person, so I had to practice the placebo effect. They would walk up to me, pat their stomach like it was hurting, and then touch their forehead like they were in pain, letting out a large sigh. I had seen this act several times now on different missions that I went on with the Afghan Army. I interpreted this gesture as the universal sign meaning, “there is really nothing wrong with me, but I saw you giving the other soldiers some pills, so I want some pills too.”

The Complete Low-FODMAP Diet: A Revolutionary Plan for Managing IBS and Other Digestive Disorders by Sue Shepherd, P. R. Gibson


placebo effect, Skype

Four out of five found the diet easy to stick to for a long period of time (months and years), and three out of four found that all of their IBS symptoms (pain, bloating, and change in bowel habits) improved markedly. This improvement was greater than we had seen for any drug or other treatment approach. This was only a preliminary experiment, however. It was still necessary to prove that the results were not due to the “placebo effect.” To do this, we rechallenged the patients whose symptoms improved on the low-FODMAP diet, this time with a double-blind, quadruple-arm, randomized, cross-over, placebo-controlled rechallenge trial in twenty-five people. This means that we tested twenty-five people by putting them on or off the diet, without them or us knowing whether or not they were taking in FODMAPs. We supplied these twenty-five people, all of whom had fructose malabsorption, with all their food, which contained no FODMAPs, for twenty-two weeks.

There are a host of other documented side effects including impotence, increased levels of aggression, nausea, urinary retention, weight loss/gain, renal impairment, tinnitus, photosensitivity, and something called “genital anesthesia.” (Another way to get genital anesthesia is to rub cocaine all over your dick. Or so I’ve heard.) Anyway, doctors know SSRIs do all of those things, but they have no idea if they actually treat some of the problems for which they are prescribed. But they work great for me. Question: how do I know it is actually the drug working and not simply the placebo effect? Answer: I don’t. Nor do I care. Whether the drug actually does something or my brain is just gullible does not matter to me at all. Interestingly, another study just came out in the journal PLoS ONE (bad name for a medical journal) showing that placebos are still effective even when the patient knows he is taking a placebo. In other words, if a doctor gives you a sugar pill and tells you it’s a sugar pill, it can still be an effective treatment.

For Rx-Promotion, revenue from repeat orders was as much as 23 percent of overall revenue. “This says a number of things, and one is that a lot of people who bought from these programs were satisfied,” Savage said, noting, however, that many of the repeat customers were purchasing controlled and habit-forming prescription drugs, including painkillers. “Maybe the drugs they bought had a great placebo effect, but my guess is these are satisfied customers and they came back because of that.” ♦ ♦ ♦ By far the most important question about the pills pimped by the spam business is the efficacy and safety of the drugs. I interviewed hundreds of U.S. residents who purchased prescription drugs from the pharmacy sites advertised through SpamIt, and received a panpoly of responses about the effectiveness of these pills.

As you probably know, most supplement companies produce cheap, junk products and try to dazzle you with ridiculous marketing claims, high-profile (and very expensive) endorsements, pseudo-scientific babble, fancy-sounding proprietary blends, and flashy packaging. They do it all because they don’t want you to realize a simple truth of this industry: supplements don’t build great physiques. Dedication to proper training and nutrition does. You see, the supplement companies are cashing in BIG on a little trick that your mind can play on you known as the placebo effect. This is the scientifically proven fact that your simple belief in the effectiveness of a medicine or supplement can make it work. People have overcome every form of illness you can imagine, mental and physical, by taking substances they believed to have therapeutic value but didn’t. I’m talking about things like treating cancer and diabetes, eliminating depression and anxiety, and lowering blood pressure and cholesterol levels by taking medically worthless substances that people believed were treatments for their problems.

Juto et al. [40] studied 21 infants with AD, of which only 20 were treated with a strict elimination diet for up to 6 weeks. Seven infants had complete resolution of their rash, 12 had some skin improvement while on the diet, and the remaining infant had no change in skin condition. While the cumulative results of the above studies provide support for the role of food allergy in AD, most of the trials failed to control confounding factors such as other potential AD triggers, placebo effect, or observer bias. In one of the original prospective follow-up studies of the natural history of food hypersensitivity in children with AD, Sampson and Scanlon [41] studied 34 subjects with AD, of whom 17 had food allergy diagnosed by doubleblind, placebo-controlled food challenges (DBPCFCs). These 17 subjects were placed on appropriate elimination diets and experienced significant improvement in their clinical symptoms.

In reviewing the literature it is difficult to draw a definitive conclusion. This is largely because reports of tartrazine-induced effects on mental function and behavior are plagued by poorly designed studies, imprecise definitions of hyperactivity, and poor reliability of behavioral outcome measures. Furthermore, it has been difficult to define study populations and segregate them from the background noise of a larger heterogeneous population of children. Placebo effects, as detected by vigilant parents, have consistently reflected parental attitudes and bias in favor of tartrazine as a perceived cause of their child’s problems. A number of articles, where poorly performed studies of tartrazine and hyperkinesis were reported, were not selected for mention in this review. Despite this gloomy introduction, there are a few studies that address most of the investigative issues and present a reasonable case in support of occasional children having tartrazine-induced mental abnormalities.

The placebo treatment was olive oil, and 2-month treatments were followed by a 1-month washout, followed by 2 months of the other treatment. Headache frequency and severity were both reduced compared to baseline by both fish oil and olive oil (p 0.0001 and p 0.01–0.03, respectively). Reductions were in the range of 65–87% for severity, duration, and frequency for both treatments. The authors suggested both modalities were having an active effect, and the magnitude of the improvement argued against placebo effect. Association of food allergy and migraine Allergy to food is self-reported more commonly in migraineurs than those with non-migrainous headache or without headache [13]. Pinnas and Vanselow have pointed out that the association between allergy and migraine is more than a 100 years old [14]. In 1885, Trousseau had included periodic headache in the allergic diathesis; Tileston in 1918 likened migraine to asthma; and the following year, Pagniez considered migraine as a manifestation of anaphylaxis [14].

After six hours of stewing, repeat the procedure: remove a few pieces, verify that the temperature is about the same, and stash the second batch in a second container in the fridge. (You could heat up the 30-minute batch, but then we’d be changing more than one variable: who’s to say that reheating doesn’t change something?) Once both samples are cold, do a taste comparison. Got kids? Do a single-blind experiment to remove the placebo effect: blindfold the kids and don’t let them know which is which. Got a spouse and kids? Do a double-blind experiment to control for both placebo effect and observer bias: have your significant other scoop the beef into the containers and label them only "A" and "B," not telling you which is which, and then go ahead and administer the blindfold test to your kids. 158°F / 70°C: Vegetable Starches Break Down Whereas meat is predominately proteins and fats, plants are composed primarily of carbohydrates such as cellulose, starch, and pectin.

Against this, it is interesting to read the defence of the necessary and dynamic notion of ‘mystery’ by Humphry Davy in his lectures (see my Prologue), or by the great twentieth-century American physicist Richard Feynman in The Meaning of it All (posthumously published in 1999). Though not a religious man, Feynman believed that science was driven by a continual dialogue between sceptical enquiry and the sense of inexplicable mystery, and that if either got the upper hand true science would be destroyed. See James Gleick, Richard Feynman and Modern Physics (1992). ♣ This is possibly the first scientific identification of the famous ‘placebo effect’, although it would not be properly tested and defined until the 1950s. It has been claimed that over 30 per cent of all patients show a ‘placebo’ response, most notably in cases of depression, heart disease and chronic muscular pain. This figure has recently been questioned, since the earlier trials may have been methodologically flawed (they lacked a neutral ‘control’ group of patients); and the definition of ‘cure’ itself is open to a high degree of subjective distortion. e.g.

The Big Fat Surprise: Why Butter, Meat and Cheese Belong in a Healthy Diet by Nina Teicholz

An ideal trial is designed to prevent either party from knowing whether a participant is assigned to the treatment or the control group. The hope is to avoid the preferential treatment that an experimenter might feel inclined to give to the intervention group (a form of bias called the “performance effect”) or, equally, the participant’s often-unconscious positive response to knowing that he or she is receiving an intervention (known as the “placebo effect”). The latter is the reason why drug studies usually hand out placebos to the control group: so that everyone has the same experience of taking a pill. Realistically, though, a diet that includes butter, cream, and meat does not look or taste like a diet without them, so a truly blind diet experiment is difficult.

Our Trauma Clinic team enrolled thirty-three nonveterans and my collaborators, former colleagues at the VA, enrolled thirty-one combat veterans. For eight weeks half of each group received Prozac and the other half a placebo. The study was blinded: Neither we nor the patients knew which substance they were taking, so that our preconceptions could not skew our assessments. Everyone in the study—even those who had received the placebo—improved, at least to some degree. Most treatment studies of PTSD find a significant placebo effect. People who screw up their courage to participate in a study for which they aren’t paid, in which they’re repeatedly poked with needles, and in which they have only a fifty-fifty chance of getting an active drug are intrinsically motivated to solve their problem. Maybe their reward is only the attention paid to them, the opportunity to respond to questions about how they feel and think. But maybe the mother’s kisses that soothe her child’s scrapes are “just” a placebo as well.

Recent research involving subjects aged twenty-four to forty-five found that half an hour’s exercise three to five times a week has the same (or better) effect on depression than drugs, regularly reducing symptoms by nearly 50 per cent. According to Science News, placebos are more effective at curing depression than either drugs or herbal remedies. In a series of trials carried out between 1979 and 1996, Seattle psychiatrist Dr Arif Khan found that St John’s Wort completely cured 24 per cent of cases, the anti-depressant drug Zoloft cured 25 per cent of cases, but the sugar-pill placebos effected a complete cure in 32 per cent of patients. In a more recent study comparing the anti-depressants Prozac and Efexor with placebos, the drugs won with a 52 per cent cure rate, but the placebos still scored impressively with 38 per cent. But as soon as the deception was revealed, the patients’ condition worsened rapidly. Many commentators believe that the context of the treatment – a clinical trial with lots of professional attention being paid to the participants – was an important factor.

Which made what happened now even more astonishing: as Billy Beane sat in his office in July, just a few months after he’d chucked out three eighths of the starting lineup, he insisted that the shake-up hadn’t been the least bit necessary. Between phone calls to other general managers he explained how the purge he’d conducted back in May, in which he’d ditched players left and right, “probably had no effect. We were 21–26 at the time. That’s a small sample size. We’d have been fine if I’d done nothing.” The most he will admit is that perhaps his actions had some “placebo effect.” And the most astonishing thing of all is that he almost believes it. Two months later, he still didn’t want to talk about Jeremy Giambi. All that mattered was that the Oakland A’s were winning again. But they were still in third place in the absurdly strong American League West, and Billy worried that this year good might not be good enough. “We can win ninety games and have a nice little season,” he said.

Anthony Colpo describes what that perfect clinical trial would look like: Such a trial would compare a group of subjects of similar sex, age and health status, who have been randomly assigned to eat diets that are identical in every respect, except that one contains a significant amount of saturated fat (the control group), while the other contains a greatly reduced amount (the treatment group). Ideally, this trial would be ‘double-blind’, meaning that both researchers and participants would be unaware of who is in the treatment group and who is in the control group, a safeguard that would help prevent researcher bias and the possibility of a placebo effect amongst the subjects.78 In fact, such studies have been done, and done relentlessly, trying to prove some link between saturated fat, cholesterol, and CHD. Some of them meet standards that are scientifically rigorous; others must be read with a cautious and educated eye. The very first was designed by Lester M. Morrison in 1946. It specifically sought to investigate the relationship between the reduction of fat consumption and cardiac deaths.

All three of the world’s great monotheisms entail prayer, “a reverent petition made to a deity or other object of worship” (American Heritage Dictionary ). It is no insult to those who pray to observe that a response to a reverent petition would be a miracle as defined above, “an event that appears unexplainable by the laws of nature and so is held to be supernatural in origin or an act of god.” I doubt whether the authenticity of prayer can be experimentally disproven. Prayer certainly has been shown to have a placebo effect. Whether the prayer itself can be deemed responsible for the success of the petition depends on whether the outcome can be identified with any certainty as not due to natural causes. Any negative results in an experiment designed for the purpose of testing the deity’s responsiveness would surely violate the Third Commandment and could be discarded on that account. If we have now arrived at the junction of myth, superstition, and religion, it’s time for me to close.

BEAUTY TIPS • Much of beauty marketing is based on the quest for eternal youth – an age-old yearning. • Renaissance beauties like Diane de Poitiers believed that drinking gold potions granted them a more youthful appearance. Gold is still used in some beauty products today. • While moisturizer improves the appearance of the skin, there is scant evidence that anti-wrinkle creams have any significant impact, although they do have a placebo effect. • Consumers are wary of the claims made by the marketers of anti-ageing creams, but feel that taking action is better than doing nothing: ‘more hope than help’. • They agree that creams can defend against future damage to the skin, particularly from overexposure to the sun. • Fear of ageing has spawned an ‘immortality business’, with doctors, scientists and thinkers considering ways in which we might live forever

Not all days are the same. Some days, you feel fine; others, you feel some pain but not a lot; and occasionally it’s awful. Of course it’s when you have one of those awful days that you are most likely to seek help by visiting a homeopath or some other dispenser of medical treatments unsupported by solid scientific evidence. The next day you wake up and … you feel better! The treatment works! The placebo effect may have helped, but you probably would have felt better the next day even if you had received no treatment at all—thanks to regression to the mean, a fact that won’t occur to you unless you stop and think carefully, instead of going with the tip-of-your-nose conclusion. This modest little mistake is responsible for many of the things people believe but shouldn’t. Keep regression to the mean in mind, however, and it becomes a valuable tool.

In the 1950s, many patients with angina and coronary artery disease underwent an operation that involved tying off an artery that runs under the breastbone. At the time, physicians believed that the procedure would increase blood flow to a heart starved of its normal supply by blockages in the coronary arteries. Then, at the end of the decade, a clinical trial showed that patients who had a sham operation did just as well as those who had the real one. Apparently, the placebo effect accounted for the fact that many patients felt better after the surgery. Other once popular procedures resulted from a misunderstanding of the biology of a particular condition. William Halstead pioneered the radical mastectomy in 1895 at the Johns Hopkins Hospital; it became routine therapy for breast cancer. When I was a medical student at Columbia in the early 1970s, no one questioned it.

Moreover, the necessity for life-long baclofen treatment could be studied in the newly described addiction model in rats (Deroche-Gamonet et al., 2004). The major limitation of this report is that it is a self-case report, not a study. But it suggests a new concept of treatment: the blockade of the expression of substance dependence symptoms with simultaneous intervention on anxiety. This case could result from a placebo effect, but I believe this to be unlikely since there has been no report of such complete and prolonged effects in clinical trials. The efficacy of high-dose baclofen should be tested for reproducibility in randomized trials under strict medical surveillance to confirm the validity of the concept of dose-dependent suppression of symptoms of alcohol dependence. Acknowledgements A physician’s signed corroboration of the author’s self-report has been provided by Dr Jean-Paul Descombey, former chief of psychiatry at Hôpital Sainte-Anne, Paris, and a member of the Administrative Council of the French Society of Alcohology.

Richard Tomkins (2009) cited fortytwo universities offering eighty-four courses in subjects such as reflexology, aromatherapy, acupuncture and herbal medicine, including fifty-one BSc degree courses. They reflect an ‘Endarkenment’, a drift from rationalist Enlightenment thinking to an emotional way of thinking associated with religion and superstition. In the absence of evidence, advocates of alternative medicine cite patient testimonials. And there is a placebo effect from treatment in which there is faith. Commodifying higher education legitimises irrationality. Any course is acceptable if there is a demand for it, if it can be sold to consumers willing to pay the price. Anybody can take a pseudo-course giving a credentialist degree ‘because you’re worth it’, which means because you or your parents can pay and because we are here to give you what you want, not what we believe to be scientific or valid based on generations of knowledge.

In Middlemarch, George Eliot described this process, evoking the history of alchemy and its delusions, but it could just as easily be applied to the sham medicine of the spicers: “Doubtless a vigorous error vigorously pursued has kept the embryos of truth a-breathing: the quest of gold being at the same time a questioning of substances, the body of chemistry is prepared for its soul, and Lavoisier is born.” Mostly these folk remedies were harmless, medically speaking; given the placebo effect, they might well have had a slightly beneficial impact. But, at least once, the use of spices as medicine seems to have backfired in a truly catastrophic way. The aromas of Oriental spice were said to combat the miasmatic air that conveyed plague. An Oxford fellow named John of Eschenden recommended “a powder of cinnamon, aloes, myrrh, saffron, mace, and cloves” to ward off the Black Death.

Personal Development for Smart People: The Conscious Pursuit of Personal Growth by Steve Pavlina


Buckminster Fuller, fear of failure, financial independence, placebo effect, side project, unbiased observer

Your beliefs should allow you to experience whatever is technically possible; they should never mislabel the possible as impossible. Subject, of course, to ethical and moral considerations, your beliefs shouldn't unduly limit your abilities. If y o u think something is impossible for y o u , then it must truly be impossible, regardless of your thinking. If a mental shift w o u l d alter your abilities via the placebo effect, then your belief is both disempowering and inaccurate. Take a m o m e n t to write d o w n some of your current beliefs about reality. W h a t do y o u believe to be true about your health, career, relationships, finances, spirituality, and so on? Then go over the eight criteria above to see how your beliefs measure up. If y o u don't like w h a t y o u see, craft more effective tenets to replace the old ones.

The more strongly individuals were attached to Chinese traditions, the more years of life they lost.3 So the idea of sympathetic threads, or the idea that “our actions run as causes, and they come back to us as effects,” cannot be entirely dismissed as hocus-pocus. There is such a thing as “cause at a distance” even within the highly rational realm of physics, and magnetism and gravity are two examples that come readily to mind. If you read about health in the newspapers, you are no doubt also familiar with the placebo effect, whereby patients respond positively to the actions of physicians even when those actions are neutral. Pills with no active ingredients—placebos—are administered as a control measure in clinical trials in order to measure the specific action of the new drug being tested versus the therapeutic benefit of simply interacting with the patient and appearing to do something—anything—for them. This is sometimes described as “mind over matter,” sometimes dismissed with “it’s all in your head.”

This demonstrates in a nutshell what I call The Prediction Effect. Predicting better than pure guesswork, even if not accurately, delivers real value. A hazy view of what’s to come outperforms complete darkness by a landslide. The Prediction Effect: A little prediction goes a long way. This is the first of five Effects introduced in this book. You may have heard of the butterfly, Doppler, and placebo effects. Stay tuned here for the Data, Induction, Ensemble, and Persuasion Effects. Each of these Effects encompasses the fun part of science and technology: an intuitive hook that reveals how it works and why it succeeds. The Field of Dreams People . . . operate with beliefs and biases. To the extent you can eliminate both and replace them with data, you gain a clear advantage. —Michael Lewis, Moneyball: The Art of Winning an Unfair Game What field of study or branch of science are we talking about here?

Once the procedure is over, you send the man home and tell him to rest for a week. If the man stops complaining, you assume that the leech treatment worked. Unfortunately for both of you, you didn’t have the benefit of modern technology back then, so you couldn’t know that a tear in the cartilage was the real culprit. Nor was there much research on the effectiveness of rest, the influence of attention from a person wearing a white coat, or the many other forms of the placebo effect (about which I wrote in some length in Predictably Irrational). Of course, physicians are not bad people; on the contrary, they are good and caring. The reason that most of them picked their profession is to make people healthy and happy. Ironically, it is their goodness and their desire to help each and every one of their patients that makes it so difficult for them to sacrifice some of their patients’ well-being for the sake of an experiment.

Korea by Simon Winchester


Albert Einstein, Berlin Wall, life extension, placebo effect, union organizing

If it is, as claimed, an elixir that promotes spermatogenesis, then I am happy to know but have no access to proof. All I do know is this: when I take ginseng, I end up feeling pretty good. (Not that I feel bad if I don’t take it—there is no suggestion that ginseng is in any way addictive.) People tell me I look fitter than for some time. And I like the taste. Maybe it is all some mighty Korean confidence trick; maybe ginseng extracts have no more than a placebo effect, and one that works wonders on the suggestible psyches of people like me. I am well aware that I might be being taken for an almighty ride and that Mr Ha and his brother tricksters at Korea’s Office of Monopoly may well be laughing behind their hands at how all the yangnom fall for all this guff about saponins and terpenoids and help jolly along Korea’s millions of dollars in profits each year.

Any plants or foods that are red, spicy, stimulating or related to blood are thus given to Mars – chilli peppers, raspberries, radishes, cranberries, garlic (which ‘removes toxins and cleanses your blood’ – pure pseudoscience, so please don’t rely on this as diet advice), root ginger, bitter coffee, black pepper, paprika, any kind of curry spice, whisky, so-called aphrodisiac foods (again, not diet advice – ‘aphrodisiac foods’ largely rely on the placebo effect) and so on. To connect to your ‘Mars energy’, a magick practitioner should integrate the colour red into their clothing and surroundings, perform Mars-specific rituals on a Tuesday (Mars day!) and light candles to bring fire into the room. If you fancy summoning Mars energy into your life, try wrapping yourself in red when you have a free Tuesday evening and enjoy a feast composed of spicy or red foods (bonus marks for both).

Thus the ACC’s perception of pain can be manipulated. Poke your finger with a pin and the ACC activates, along with those brain regions telling you which finger and what parameters of pain. Make someone believe that the inert cream you just smeared on his finger is a powerful painkiller, and when you poke his finger, the “it’s my finger, not my toe” circuitry still activates. But the ACC falls for the placebo effect and stays silent. Obviously the ACC receives inputs from interoceptive and exteroceptive outposts. Equally logically, it sends lots of projections into the sensorimotor cortex, making you very aware of and focused on the body part that hurts. But the sophistication of the ACC, the reason it sits up there in the frontal cortex, is apparent when considering another type of pain. Back to chapter 6 and the Cyberball game where subjects in brain scanners play catch with a virtual ball on a computer screen, tossing it back and forth, and the other two players stop throwing the ball to you.

Later, when the county went bankrupt in one of Americaʼs biggest financial scandals, Moorlachʼs earlier jeremiads appeared on journalistsʼ computer screens. He subsequently was hailed as a visionary. The idea of a predictions registry may have originated when Sir Francis Galton (1822—1911) attempted to perform experiments statistically measuring the efficacy of prayer. (He discovered what skeptics now call the “placebo effect.”) In the 1970s, efforts were made to catalog predictions using the crude technique of mailing postcards to a post office box in New York City, but sorting through shoe boxes did not prove an efficient or comprehensive method of correlating results, and the effort collapsed. The Internet has changed all that. For example, a “predictions market” has been set up by Robin Hanson, a researcher at the University of California at Berkeley.

In 1961 he taught probability and statistics on NBC’s early-morning Continental Classroom series; his lectures were viewed by more than a million people and taken for credit by 75,000. In medical research Mosteller pioneered meta-analysis and strongly advocated randomized clinical trials, fair tests of medical treatments, and data-based medicine. He was one of the first to conduct large-scale studies of placebo effects, evaluations of many medical centers, collaborations between physicians and statisticians, and the use of large, mainframe computers. How did Mosteller juggle a massive Bayesian analysis on top of his other work? He looked tubby and rumpled, but he was a superb organizer and utterly unfazed by controversy. He was genial; he engaged critics with a touch of humor, and he seemed to believe they were entitled to opinions he disagreed with.

The umpire asked us to remove our PLACARD from the bleacher wall, claiming that it obstructed the view of the hitters. placebo (pluh-SEE-bo), noun A medicine having no fixed medical purpose or healing property given either to pacify a patient or, as a control method, to test the effectiveness of another drug. A placebo is administered as though it were a medication or drug, yet is neutral from a medical standpoint. Scientists are still uncertain as to exactly what causes the PLACEBO effect, in which some patients taking a “ fake” drug actually improve. placid (PLAH-sid), adjective Undisturbed; smooth. That which appears calm or undisturbed on the surface can be said to be placid. The PLACID country surroundings were just the change Caitlyn needed after three months in noisy Manhattan. plague (playg), noun A broad-based affliction. A plague is a widespread calamity usually associated with a severe and sudden incidence of disease in a population.

This proved something important about imagining: It’s not merely the act of imagining that raises Gut’s estimate of how likely something is, it’s how easy it is to imagine that thing. If imagining is easy, Gut’s estimate goes up. But if it is a struggle to imagine, it will feel less likely for that reason alone. It may be a little surprising to think that the act of imagining can influence our thoughts, but in many different settings—from therapy to professional sports—imagining is used as a practical tool whose effectiveness is just as real as the famous placebo effect. Imagination is powerful. When the ads of lottery corporations and casinos invite us to imagine winning—one lottery’s slogan is “Just Imagine”—they do more than invite us to daydream. They ask us to do something that elevates our intuitive sense of how likely we are to win the jackpot—which is a very good way to convince us to gamble. There is no “just” in imagining. This isn’t the only potential problem with Gut’s use of the Example Rule.

It was empty and desolate, and everything I’d accumulated at the previous location was gone. I had no bed, no food, no water, no medicine, no radio. But all I cared about was the incredible pain that wasn’t subsiding now, even as I lay still. The trip in the car had aced it. That splint had to come off. The fire in my thigh was incredibly intense, and I didn’t even have the aspirin now for a “placebo effect.” Firimbi squatted down beside me. I must have looked bad, because he looked pretty worried. I gripped his forearm, hard. “You’ve got to get the doctor,” I said. My voice was dry and raspy. “Dr. Kediye. Right now. This goddamn thing has got to come off.” I must have been fairly convincing, because he hustled out of the place. Without his oil lantern it was pitch dark. I lay there for a long time, not moving, just breathing and waiting.

Clarinex is a differently packaged version of Claritin, which is of questionable efficacy in the first place and is sold over the counter abroad for vastly less. Promoted as though it must be some sort of elixir, the ubiquitous “purple pill,” Nexium, is essentially AstraZeneca’s old heartburn drug Prilosec with a minor chemical twist that allowed the company to extend its patent. (Perhaps not coincidentally researchers have found that purple is a particularly good pill color for inducing placebo effects.)35 Sad but ironically true, me-too or copycat drugs are pretty much the only available tool capable of inducing some kind of competition in an otherwise monopolized market. Because patent protection lasts long enough to make future entry by generics nearly irrelevant, the limited degree of substitutabil-ity and price competition that copycat drugs bring about is actually valuable. We are not kidding here, and this is a point that many commentators are often missing in their anti–Big Pharma crusade.

(After all, glucosamine was once on the fringes, and now it’s an accepted therapy for osteoarthritis.) Some drugs may make your condition worse or cause interactions with medications you’re taking (such as evening primrose oil and anticoagulants); many herbs should not be taken before surgery; and some herbs (like kava) may even be toxic to the liver. This is one area where you need to do your homework. Realize that many remedies have a powerful placebo effect—if you believe something is going to help you, chances are it will. It sounds weird, but if you have to have one of these diseases, this is a great time. They have made leaps and bounds in research. There is some real hope 378 The Autoimmune Connection for MS and other diseases, and you need to hang on to that hope. They’ve made more progress in the last few years than they have in the last twentyfive years.

Dr Ho ground his plants to powder and soaked them in hot spring waters – trying them out on the villagers, varying the amounts and the mixes depending on the ailments presented and the age and sex of those he treated. Before long he had a following: the Chinese have always been eager for natural cures, for their own version of the Ayurvedic arts practised farther west, and Dr Ho's discoveries on the mountainsides seemed to work wonders, either from their chemistry or from their placebo effect. He next combined his newfound pharmaceutical skills with his professed lifelong commitment to the way of Taoism – a philosophy that in any case sets great store by internal hygiene, the quest for immortality, internal alchemy and healing. And in 1985, formally and with some ceremony attended by Taoist priests, he established himself as a full-blown Taoist herbal healer. He sat back and anticipated a late middle age of well-meaning obscurity.

Meet Seth Roberts, who claims that eating butter makes him faster—well, this is what his data says anyway (“Two years ago I discovered that butter—more precisely, substitution of butter for pork fat—made me faster,” begins his blog post)—or Sanjiv Shah, who thinks that wearing yellow glasses before going to bed improves his sleeping patterns (it’s all in the data, stupid!). Of course, some self-trackers are aware that their conclusions may not be, well, scientifically valid; as one such enthusiast told the Economist, “With self-tracking you never really know whether it is your experiment that is affecting the outcome, or your expectations of the experiment.” In science, this is widely known as the placebo effect, and in academic experiments every effort is made to minimize its influence. With the Quantified Self, however, what matters is not knowledge per se but, rather, the utility of various knowledge claims in helping improve one’s health or sex life. Most curiously, one doesn’t need to know how such knowledge will be used; much of it is generated and stored preemptively. As Wolf points out about his fellow Quantified Self members, “Although they may take up tracking with a specific question in mind, they continue because they believe their numbers hold secrets that they can’t afford to ignore, including answers to questions they have not yet thought to ask.”

Most of the spiritual teachers in The Secret are wealth-seminar leaders who display the book’s logo on their ads and websites. The Secret has certainly worked wonders for its marketers: as of this writing, more than two million DVDs have been sold, and the book hit number one on the New York Times Best-Seller List of hardcover advice books. While positive thinking no doubt has its benefits—from the placebo effect to good old self-confidence—The Secret tries to justify itself not only in the language of pop psychology but also in that of modern physics. According to the book, happy thoughts will do more than affect behavior. The Secret claims that interrelatedness of matter and energy—Einstein’s E = mc2—allows people to change reality to their liking by changing the way they think about it. Thought is presumably the energy in this schema, and reality is the matter.

The reverse could also have been true: the women who were already going to have a lower mortality rate might have been more likely to take hormones. In other words, perhaps it was their greater propensity toward health or the absence of disease that led them to take the hormones, and not the reverse. The third possibility is that the women who took the hormones believed that they were doing something that would protect their health and that this placebo effect played a role in keeping them healthier. The Nurses’ Health Study researchers statistically adjusted their results for many potentially confounding factors: body weight, cigarette smoking, high blood pressure, high cholesterol, early heart attack in a parent, history of breast cancer in mother or sister, previous use of birth control pills, number of children, age of onset of period, diet, alcohol use, multivitamin use, vitamin E use, aspirin use, and regular exercise.

In George Bernard Shaw’s words, ‘The fact that a believer is happier than a skeptic is no more to the point than the fact that a drunken man is happier than a sober one.’ Part of what a doctor can give a patient is consolation and reassurance. This is not to be dismissed out of hand. My doctor doesn’t literally practise faith-healing by laying on of hands. But many’s the time I’ve been instantly ‘cured’ of some minor ailment by a reassuring voice from an intelligent face surmounting a stethoscope. The placebo effect is well documented and not even very mysterious. Dummy pills, with no pharmacological activity at all, demonstrably improve health. That is why double-blind drug trials must use placebos as controls. It’s why homoeopathic remedies appear to work, even though they are so dilute that they have the same amount of active ingredient as the placebo control – zero molecules. Incidentally, an unfortunate by-product of the encroachment by lawyers on doctors’ territory is that doctors are now afraid to prescribe placebos in normal practice.

In the most direct test of this catalyst hypothesis, Walter Pahnke,39 a physician working on a dissertation in theology, brought twenty graduate students in theology into a room below the chapel at Boston University on Good Friday 1962. He gave ten of the students 30 milligrams of psilocybin; the other ten were given identical-looking pills containing vitamin B5 (nicotinic acid), which creates feelings of tingles and flushing on the skin. T h e vitamin B5 is what's known as an active placebo: It creates real bodily feelings, so if the beneficial effects of psilocybin were just placebo effects, the control group would have good reason to show them. Over the next few hours, the whole group listened (via speakers) to the G o o d Friday service going on in the chapel upstairs. Nobody, not even Pahnke, knew who had taken which pill. But two hours after the pills were taken, there could be no doubt. T h o s e who had taken the placebo were the first to feel something happening, and they a s s u m e d they had gotten the psilocybin.

Spices and perfumes permeated gloves, hot beverages, liqueurs, and most of the recipes used in wealthy households. Historians have suggested that rare spices were originally valued because of their medicinal properties. For example, one authority points out that the contents of a medieval French spice store and a nineteenth-century American pharmacy would have been nearly identical. But were these "drugs" effective? The placebo effect, one of the most powerful forces in the therapeutic armamentarium, derives in no small part from the exoticism of the ingredients or methods used. None of the spices mentioned in this chapter has any scientifically proven medicinal value, and those plant products that do are often quite common, such as the heart drug digitalis, from the lovely but lowly foxglove. Roman and Greek physicians prescribed the rare spice galangal "for the kidneys .114 Precisely what medical conditions were meant by this?

What would happen if we could rewrite our inner monologues, or even silence them completely on occasion?8 As of 2016, transcranial stimulators are still in their infancy, and it is unclear if and when they will become a mature technology. So far they provide enhanced capabilities for only short durations, and even Sally Adee’s twenty-minute experience may be quite exceptional (or perhaps even the outcome of the notorious placebo effect). Most published studies of transcranial stimulators are based on very small samples of people operating under special circumstances, and the long-term effects and hazards are completely unknown. However, if the technology does mature, or if some other method is found to manipulate the brain’s electric patterns, what would it do to human societies and to human beings? People may well manipulate their brain’s electric circuits not just in order to shoot terrorists, but also to achieve more mundane liberal goals.

Insulin was “an excellent fattening substance,” Erich Grafe wrote in Metabolic Diseases and Their Treatment. Grafe believed that the fattening effect of insulin is likely “due to improved combustion of carbohydrate and increased synthesis of glycogen and fat.” In the United States, however, the conventional wisdom came from Louis Newburgh and his colleagues at the University of Michigan. When insulin increases weight, Newburgh said, it does so either through the power of suggestion—a placebo effect—or by a reduction of blood sugar to the point where the patient eats to avoid very low blood sugar (hypoglycemia) and the accompanying symptoms of dizziness, weakness, and convulsions. When Rony reviewed the experimental and clinical reports in 1940, he considered any conclusion to be premature. Because obese individuals tend to have high blood sugar, rather than low, Rony said, it was hard to imagine how insulin, which lowered blood sugar, could cause obesity.

Still, the CDC shows that life expectancy at age 20 only increased from 42.79 (additional years) in 1900–1902 to 51.2 in 1949–1951 and to 58.2 in 2002. 2 A technical comment: in the so-called Bayesian (or conditional probability) analysis, it would be equivalent to looking at A conditional on B rather than B conditional on A. 3 One example of lack of empirical wisdom in the use of “evidence”: in a New York Times Magazine article, a doctor who claimed that he stopped eating sugar because of its potential harm was apologetic for doing so “without full evidence.” The best test of empirical wisdom in someone is in where he puts the burden of evidence. 4 I am trying to avoid discussing the placebo effect; I am in the business of nonlinearities and it does not relate to the nonlinearities argument. 5 Some people claim that we need more fat than carbohydrates; others offer the opposite (they all tend to agree on protein, though few realize we need to randomize protein intake). Both sides still advocate nonrandomness in the mixing and ignore the nonlinearities from sequence and composition. 6 The principal disease of abundance can be seen in habituation and jadedness (what biologists currently call dulling of receptors); Seneca: “To a sick person, honey tastes better.”

She circled her rosary like a Tibetan monk on a prayer wheel. But my situation was so perilous she wasn’t going to leave it just to heaven to deliver a fix. Having suffered months of morning sickness while carrying the twins, she was an expert on puking and was convinced I could be cured with the right breakfast. The specifics of the meal she cooked for me have long left my memory, but it worked. No doubt it was just a placebo effect, but I didn’t care. I got through a flight without seeing that breakfast again. And then another. And another. My self-confidence roared back. My flying career was saved by Donna. From Mt. Home I was directed to Saigon, Republic of Vietnam. I would be flying with the 16th Tactical Reconnaissance Squadron from Tan Son Nhut Air Base. Donna and the babies would wait out my tour in a Kirtland AFB house in Albuquerque.

On the other hand, I think she really does believe she has deceived herself. So although she does not receive any benefit of believing in God—because she doesn’t—she honestly believes she has deceived herself into believing in God, and so she honestly expects to receive the benefits that she associates with deceiving oneself into believing in God; and that, I suppose, ought to produce much the same placebo effect as actually believing in God. And this may explain why she was motivated to earnestly defend the statement that she believed in God from my skeptical questioning, while never saying “Oh, and by the way, God actually does exist” or even seeming the slightest bit interested in the proposition. * 84 Belief in Self-Deception I spoke of my conversation with a nominally Orthodox Jewish woman who vigorously defended the assertion that she believed in God, while seeming not to actually believe in God at all.
