One of the rules of thumb people often use when making judgments is the so-called availability heuristic. Suppose you’re asked, “Which are more frequent: English words that start with the letter ‘R,’ or those that have ‘R’ as their third letter?” Using the availability heuristic, most people react by trying to think of examples in each category. That approach usually works well, since examples of things that occur more frequently are in fact generally easier to summon from memory. And since most people find it easier to think of examples of words starting with “R,” the availability heuristic leads them to answer that such words occur more frequently.

And since most people find it easier to think of examples of words starting with “R,” the availability heuristic leads them to answer that such words occur more frequently. Yet English words with “R” in the third slot are actually far more numerous. The availability heuristic fails here because frequency isn’t the only thing that governs ease of recall. We store words in our memories in multiple ways—by their meanings, by the sounds they make and the images they evoke, by their first letters, and by numerous other features. But virtually no one stores words in memory by the identity of their third letter. The availability heuristic suggests that when we construct narratives about how the world works, we rely more heavily on information that happens to be more accessible from memory.

They probably also know, in some abstract sense, that they might not have done as well in some other environments. Yet their day-to-day experiences provide only infrequent reminders to reflect on how fortunate they were not to have been born in, say, a war-torn country like Zimbabwe. The availability heuristic biases our personal narratives in a second way, because events that work to our disadvantage are systematically easier to recall than those that affect us positively. My Cornell colleague Tom Gilovich invokes a metaphor involving headwinds and tailwinds to describe this asymmetry. If any of you go running or ride a bike, you’ll know that when you’re running or bicycling into the wind, you’re very aware of it.

This possibility suggests that we need a kind of behavioral science for judgments of morality, and not merely judgments of fact.11 Moral heuristics are pervasive, and they can go wrong, no less than heuristics of other kinds. Consider an analogy: The availability heuristic helps people to come up with estimates of probability, and it generally works well. When we learn of an incident in which certain actions produced serious harm, we update our probability judgments. The updating is perfectly sensible. Use of the availability heuristic can be seen as a kind of rough-and-ready statistical analysis—and perhaps it is even better than that. The problem is that use of the availability heuristic can also go badly wrong, leading to wildly exaggerated fears (or to unhealthy complacency).

Perhaps the most important point is that disclosure requirements may turn out to be ineffective with respect to optimistically biased consumers. Any such requirements should be devised so as to reduce that risk. Graphic warnings, grabbing the attention of System 1, are a possibility here. PROBLEMS WITH PROBABILITY System 1 does not handle probability well. One problem is the availability heuristic. When people use that heuristic, they make judgments about probability by asking whether a recent event comes readily to mind.63 If an event is cognitively “available,” people might well overestimate the risk. If an event is not cognitively available, they might underestimate the risk.64 In deciding whether it is dangerous to walk in a city at night, to text while driving, or to smoke, people often ask about incidents of which they are aware.

If an event is not cognitively available, they might underestimate the risk.64 In deciding whether it is dangerous to walk in a city at night, to text while driving, or to smoke, people often ask about incidents of which they are aware. While System 2 might be willing to do some calculations, System 1 works quickly, and it is pretty simple to use the availability heuristic. Instead of asking hard questions about statistics, System 1 asks easy questions about what comes to mind. “Availability bias” can lead to significant mistakes about the probability of bad outcomes, taking the form of either excessive fear or unjustified complacency.65 A distinct but related finding is that people sometimes do not make judgments on the basis of the expected value of outcomes, and they may neglect the central issue of probability, particularly when emotions are running high.66 In such cases, people may focus on the outcome and not on the probability that it will occur.67 If there is a small chance of catastrophe—the loss of a child, a fatal cancer—the outcome may dominate people’s thoughts, rather than the statistical likelihood that it will happen.


Infotopia: How Many Minds Produce Knowledge by Cass R. Sunstein

We are also subject to identifiable biases, which can produce big mistakes.1 A growing literature explores the role of these heuristics and biases and their relationship to law and policy. For example, people err because they use the availability heuristic to answer difficult questions about probability. How / 75 likely is a terrorist attack, a hurricane, a traffic jam, an accident from a nuclear power plant, a case of venereal disease? When people use the availability heuristic, they answer a question of probability by asking whether examples come readily to mind.2 The point very much bears on private and public responses to risks—suggesting, for example, that people will be especially responsive to the dangers of AIDS, crime, earthquakes, and nuclear power plant accidents if examples are easy to recall.

For example, whether people will buy insurance for natural disasters is greatly affected by recent experiences.4 In the aftermath of an earthquake, people become far readier to buy insurance for earthquakes, but their readiness to do so declines steadily from that point, as vivid memories recede. Use of the availability heuristic is not irrational, but it can easily lead to serious errors of fact. After the 2005 disaster produced by Hurricane Katrina in the United States, it was predictable that significant steps would be taken to prepare for hurricanes—and also predictable that before that disaster, such steps would be quite inadequate. 76 / Infotopia Most people are also strikingly vulnerable to framing effects, making different decisions depending on the wording of the problem.

If so, the many minds on the jury are likely to amplify rather than to correct those biases.9 Deliberating groups have also been found to amplify, rather than to attenuate, reliance on the representativeness heuristic.10 Such groups fall prey to even larger framing effects than individuals, so that when the same situation is described in different terms, groups are especially likely to be affected by the redescriptions.11 Groups show more overconfidence than group members;12 78 / Infotopia they are even more affected by the biasing effect of bad arguments from lawyers.13 In an especially revealing finding, groups have been found to make more, rather than fewer, conjunction errors (believing that A and B are more likely to be true than A alone) than individuals when individual error rates are high—though fewer when individual error rates are low.14 Groups do demonstrate a decreased level of reliance on the availability heuristic, but the decrease is slight, even when use of that heuristic leads to clear errors.15 Here’s a disturbing finding, one with great relevance to group behavior in both politics and business: Groups are more likely than individuals to escalate their commitment to a course of action that is failing—and all the more so if members identify strongly with the groups of which they are a part.16 There is a clue here about why companies, states, and even nations often continue with projects and plans that are clearly going awry.

At night I wrote Attention and Effort. It was a busy year. One of our projects was the study of what we called the availability heuristic. We thought of that heuristic when we asked ourselves what people actually do when they wish to estimate the frequency of a category, such as “people who divorce after the age of 60” or “dangerous plants.” The answer was straightforward: instances of the class will be retrieved from memory, and if retrieval is easy and fluent, the category will be judged to be large. We defined the availability heuristic as the process of judging frequency by “the ease with which instances come to mind.” The statement seemed clear when we formulated it, but the concept of availability has been refined since then.

On another occasion, Amos and I wondered about the rate of divorce among professors in our university. We noticed that the question triggered a search of memory for divorced professors we knew or knew about, and that we judged the size of categories by the ease with which instances came to mind. We called this reliance on the ease of memory search the availability heuristic. In one of our studies, we asked participants to answer a simple question about words in a typical English text: Consider the letter K. Is K more likely to appear as the first letter in a word OR as the third letter? As any Scrabble player knows, it is much easier to come up with words that begin with a particular letter than to find words that have the same letter in the third position.

The Paradox of Choice: Why More Is Less by Barry Schwartz

Most of us give weight to these kinds of stories because they are extremely vivid and based on a personal, detailed, face-to-face account. Kahneman and Tversky discovered and reported on people’s tendency to give undue weight to some types of information in contrast to others. They called it the availability heuristic. This needs a little explaining. A heuristic is a rule of thumb, a mental shortcut. The availability heuristic works like this: suppose someone asked you a silly question like “What’s more common in English, words that begin with the letter t or words that have t as the third letter?” How would you answer this question? What you probably would do is try to call to mind words that start with t and words that have t as the third letter.

Because I had an easier time recalling words that start with t than recalling words with t as the third letter, I must have encountered them more often in the past. So there must be more words in English that start with t than have it as the third letter.” But your conclusion would be wrong. The availability heuristic says that we assume that the more available some piece of information is to memory, the more frequently we must have encountered it in the past. This heuristic is partly true. In general, the frequency of experience does affect its availability to memory. But frequency of experience is not the only thing that affects availability to memory.

So it’s the salience of starting letters that makes t-words come easily to mind, while people mistakenly think it’s the frequency of starting letters that makes them come easily to mind. In addition to affecting the ease with which we retrieve information from memory, salience or vividness will influence the weight we give any particular piece of information. There are many examples of the availability heuristic in operation. When college students who are deciding what courses to take next semester are presented with summaries of course evaluations from several hundred students that point in one direction, and a videotaped interview with a single student that points in the other direction, they are more influenced by the vivid interview than by the summary judgments of hundreds.

Of course, Ukraine was not the source of the Russian hacks; it was the target. But the Availability Heuristic works by association. Since Ukraine was associated with hacking, the heuristic lent credence to the claim that the hacking came from Ukraine. For similar reasons, phishing emails routinely refer to current events, like natural disasters and infectious diseases, when asking for donations. Because these events are vivid and sensational, the Availability Heuristic lends credibility to scams that mention them. The scams are believable because the events they mention are memorable. Closely related to the Availability Heuristic is the Affect Heuristic.

Kahneman and Tversky hypothesized that when people are asked questions about how common objects are, they often respond to a different, easier question. Instead of “How common is this?” they answer, “How memorable is this?” According to the Availability Heuristic, the more available an object is in memory, the more common it will be judged to be. Because we assume that memorability is correlated with frequency, the media greatly affects our judgments. Accidents, for example, are thought to be greater causes of death than diabetes because car and plane crashes are covered by the news, while the more common diabetes deaths are not. The Availability Heuristic, therefore, biases our perception of frequency toward exceptional, especially vivid, events.

MacGregor, “The Affect Heuristic,” European Journal of Operational Research 177 (2007): 1333–52. downplay its benefits: The Affect Heuristic works partially through the Availability Heuristic. The more you like something, the more likely its benefits will be available to you in memory. Conversely, the more available an event is in memory, the greater the affect experienced. For the relation between these two heuristics, see Thorsten Pachur et al., “How Do People Judge Risks: Availability Heuristic, Affect Heuristic, or Both?,” Journal of Experimental Psychology: Applied 18, no. 3 (2012): 314–30. an urn: Dale T.

It’s easier to come up with words beginning with r than words having an r in the third position—because we “file” words in our minds by their initial letters and so they’re more available as we rummage through memory. But in fact there are more words with r in the third position. One problem with using the availability heuristic for judgments of frequency or plausibility is that availability is tangled up with salience. Deaths by earthquake are easier to recall than deaths by asthma, so people overestimate the frequency of earthquake deaths in their country (by a lot) and underestimate the frequency of asthma deaths (hugely). Heuristics, including the representativeness heuristic and the availability heuristic, operate quite automatically and often unconsciously. This means it’s going to be hard to know just how influential they can be.

Honesty in the future is best predicted by honesty in the past, not by whether a person looks you steadily in the eye or claims a recent religious conversion. Competence as an editor is best predicted by prior performance as an editor, or at least by competence as a writer, and not by how verbally clever a person seems or how large the person’s vocabulary is. Another important heuristic Tversky and Kahneman identified is the availability heuristic. This is a rule of thumb we use to judge the frequency or plausibility of a given type of event. The more easily examples of the event come to mind, the more frequent or plausible they seem. It’s a perfectly helpful rule most of the time. It’s easier to come up with the names of great Russian novelists than great Swedish novelists, and there are indeed more of the former than the latter.

The chapters are intended to help you build statistical heuristics—rules of thumb that will suggest correct answers for an indefinitely large number of everyday life events. These heuristics will shrink the range of events to which you will apply only intuitive heuristics, such as the representativeness and availability heuristics. Such heuristics invade the space of events for which only statistical heuristics are appropriate. Two years of thinking about rats or brains or memory for nonsense syllables produces little improvement in ability to apply statistical principles to everyday life events. Students in the hard areas of psychology may learn scarcely more than students in chemistry and law.

The peace researcher John Galtung pointed out that if a newspaper came out once every fifty years, it would not report half a century of celebrity gossip and political scandals. It would report momentous global changes such as the increase in life expectancy.10 The nature of news is likely to distort people’s view of the world because of a mental bug that the psychologists Amos Tversky and Daniel Kahneman called the Availability heuristic: people estimate the probability of an event or the frequency of a kind of thing by the ease with which instances come to mind.11 In many walks of life this is a serviceable rule of thumb. Frequent events leave stronger memory traces, so stronger memories generally indicate more-frequent events: you really are on solid ground in guessing that pigeons are more common in cities than orioles, even though you’re drawing on your memory of encountering them rather than on a bird census.

Not surprisingly, many people have a fear of flying, but almost no one has a fear of driving. People rank tornadoes (which kill about fifty Americans a year) as a more common cause of death than asthma (which kills more than four thousand Americans a year), presumably because tornadoes make for better television. It’s easy to see how the Availability heuristic, stoked by the news policy “If it bleeds, it leads,” could induce a sense of gloom about the state of the world. Media scholars who tally news stories of different kinds, or present editors with a menu of possible stories and see which they pick and how they display them, have confirmed that the gatekeepers prefer negative to positive coverage, holding the events constant.13 That in turn provides an easy formula for pessimists on the editorial page: make a list of all the worst things that are happening anywhere on the planet that week, and you have an impressive-sounding case that civilization has never faced greater peril.

To estimate risk, we should tally the number of instances of an event and mentally divide it by the number of occasions on which it could have taken place. Yet one of the signature findings in the science of human judgment is that this is not how human probability estimation generally works. Instead, people judge the probability of events by the ease with which instances come into mind, a habit that Tversky and Kahneman called the availability heuristic.11 We use the ranking from our brain’s search engine—the images, anecdotes, and mental videos it coughs up—as our best guess of the probabilities. The heuristic exploits a feature of human memory, namely that recall is affected by frequency: the more often we encounter something, the stronger the trace it leaves in our brains.

Americans guess 24 percent; polls indicate 4.5 percent.14 African Americans? About a third, people say, around two and half times higher than the real figure, 12.7 percent. That’s still more accurate than their estimate for another conspicuous minority, Jews, where respondents are off by a factor of nine (18 versus 2 percent).15 The availability heuristic is a major driver of world events, often in irrational directions. Other than disease, the most lethal risk to life and limb is accidents, which kill about five million people a year (out of 56 million deaths in all), about a quarter of them in traffic accidents.16 But except when they take the life of a photogenic celebrity, car crashes seldom make the news, and people are insouciant about the carnage.

Instead we judge the probability that an instance belongs to a category by how representative it is: how similar it is to the prototype or stereotype of that category, which we mentally represent as a fuzzy family with its crisscrossing resemblances (chapter 3). A cancer patient, typically, gets a positive diagnosis. How common the cancer is, and how common a positive diagnosis is, never enter our minds. (Horses, zebras, who cares?) Like the availability heuristic from the preceding chapter, the representativeness heuristic is a rule of thumb the brain deploys in lieu of doing the math.6 Tversky and Kahneman demonstrated base-rate neglect in the lab by telling people about a hit-and-run accident by a taxi late at night in a city with two cab companies: Green Taxi, which owns 85 percent of the cabs, and Blue Taxi, which owns 15 percent (those are the base rates, and hence the priors).

That is to say, a faulty application of the generally useful representativeness rule biases us toward the perception of order where it does not exist. Heuristic Bias and the Availability Heuristic To recap, heuristics help us make complex decisions rapidly in spite of the limitations of human intelligence, but they can cause those decisions to be biased. The notion of heuristic bias is easily explained by considering the availability heuristic. We rely on the availability heuristic to estimate the likelihood of future events. It is based on the reasonable notion that the more easily we can bring to mind a particular class of events, the more likely it is that such events will occur in the future.

It is based on the reasonable notion that the more easily we can bring to mind a particular class of events, the more likely it is that such events will occur in the future. Events that are easily brought to mind are said to be cognitively available. For example, plane crashes are a class of events with high cognitive availability. The availability heuristic makes a certain amount of sense. The ability to recall a class of events is indeed related to how frequently they have occurred in the past, and it is also true that events that have happened fre- 88 METHODOLOGICAL, PSYCHOLOGICAL, PHILOSOPHICAL, STATISTICAL FOUNDATIONS quently in the past are generally more likely to occur in the future.

This is in keeping with one theory of probability that asserts that the future likelihood of an event is related to its historical frequency.143 Taken as a class, thunderstorms have been more frequent in the past than asteroid impacts, and they do indeed have a higher future likelihood. The problem with the availability heuristic is that there are factors that can enhance an event’s cognitive availability that have nothing to do with its historical frequency and are, therefore, irrelevant to estimating its future likelihood. Consequently, our judgments of likelihood are sometimes falsely inflated by the intrusion of these irrelevant factors.

In this case, the doctor’s error was to rule out a heart attack because the patient appeared to be a model of health and fitness. “You have to be prepared in your mind for the atypical and not so quickly reassure yourself, and the patient, that everything is okay,” the doctor later mused.10 The availability heuristic, judging the frequency or probability of an event based on what is readily available in memory, poses a related challenge. We tend to give too much weight to the probability of something if we have seen it recently or if it is vivid in our mind. Groopman tells of a woman who came to the hospital suffering from a low-grade fever and a high respiratory rate.

She had taken too many aspirin in an attempt to treat a cold, and her fever and respiratory rate were classic symptoms. But the doctor overlooked them because of the vividness of the viral pneumonia. Like representativeness, availability encourages us to ignore alternatives.11 Think carefully about how the representativeness and availability heuristics may impose on your decisions. Have you ever judged someone solely based on how he or she looks? Have you ever feared flying more after hearing of a plane crash? If the answer is yes, you are a normal human. But you also risk misunderstanding, or missing altogether, plausible outcomes. Is the Trend Your Friend?

“Each of the problems had an objectively correct answer,” Amos and Danny wrote, after they were done with their strange mini-experiments. “This is not the case in many real-life situations where probabilities are judged. Each occurrence of an economic recession, a successful medical operation, or a divorce, is essentially unique, and its probability cannot be evaluated by a simple tally of instances. Nevertheless, the availability heuristic may be applied to evaluate the likelihood of such events. “In judging the likelihood that a particular couple will be divorced, for example, one may scan one’s memory for similar couples which this question brings to mind. Divorces will appear probable if divorces are prevalent among the instances that are retrieved in this manner.”

This particular rule they used to judge probabilities (the easier it is for me to retrieve from my memory, the more likely it is) often worked well. But if you presented people with situations in which the evidence they needed to judge them accurately was hard for them to retrieve from their memories, and misleading evidence came easily to mind, they made mistakes. “Consequently,” Amos and Danny wrote, “the use of the availability heuristic leads to systematic biases.” Human judgment was distorted by . . . the memorable. Having identified what they took to be two of the mind’s mechanisms for coping with uncertainty, they naturally asked: Are there others? Apparently they were unsure. Before they left Eugene, they jotted down some notes about other possibilities.

“We really couldn’t think of others,” said Danny. “There seemed to be very few mechanisms.” Just as they never tried to explain how the mind forms the models that underpinned the representativeness heuristic, they left mostly to one side the question of why human memory worked in such a way that the availability heuristic had such power to mislead us. They focused entirely on the various tricks it could play. The more complicated and lifelike the situation a person was asked to judge, they suggested, the more insidious the role of availability. What people did in many complicated real-life problems—when trying to decide if Egypt might invade Israel, say, or their husband might leave them for another woman—was to construct scenarios.

However, heuristics can also lead investors to make biased decisions. One facet of successful decision making is gaining an understanding of these biases so as to mitigate their cost.7 The availability heuristic allows investors to assess the frequency or likely cause of an event by the degree to which similar events are “available” in memory. Ease of recall is one bias that emanates from the availability heuristic. In other words, investors or managers may place greater emphasis on information that is available than on information that is relevant. I believe this bias is at the heart of the janitor’s-dream problem.

So we substitute an easier question: “Can I easily recall a lion attacking someone from the long grass?” That question becomes a proxy for the original question and if the answer is yes to the second question, the answer to the first also becomes yes. So the availability heuristic—like Kahneman’s other heuristics—is essentially a bait-and-switch maneuver. And just as the availability heuristic is usually an unconscious System 1 activity, so too is bait and switch.18 Of course we aren’t always oblivious to the machinations of our minds. If someone asks about climate change, we may say, “I have no training in climatology and haven’t read any of the science.

If that memory comes to you easily—it is not the sort of thing people tend to forget—you will conclude lion attacks are common. And then start to worry. Spelling out this process makes it sound ponderous, slow, and calculating but it can happen entirely within System 1—making it automatic, fast, and complete within a few tenths of a second. You see the shadow. Snap! You are frightened—and running. That’s the “availability heuristic,” one of many System 1 operations—or heuristics—discovered by Daniel Kahneman, his collaborator Amos Tversky, and other researchers in the fast-growing science of judgment and choice. A defining feature of intuitive judgment is its insensitivity to the quality of the evidence on which the judgment is based.

“Respondents put too much confidence in the result of small samples and their statistical judgment showed little sensitivity to sample size.”The puzzling aspect is that not only should they have known better, “they did know better.” And yet . . . I will next list a few more heuristics. (1) The availability heuristic, which we saw in Chapter 3 with the earthquake in California deemed more likely than catastrophe in the entire country, or death from terrorism being more “likely” than death from all possible sources (including terrorism). It corresponds to the practice of estimating the frequency of an event according to the ease with which instances of the event can be recalled. (2) The representativeness heuristic: gauging the probability that a person belongs to a particular social group by assessing how similar the person’s characteristics are to the “typical” group member’s.

Simpson had 1/500,000 chance of not being the killer from the blood standpoint (remember the lawyers used the sophistry that there were four people with such blood types walking around Los Angeles) and adding to it the fact that he was the husband of the person and that there was additional evidence, then (owing to the compounding effect) the odds against him rise to several trillion trillion. “Sophisticated” people make worse mistakes. I can surprise people by saying that the probability of the joint event is lower than either. Recall the availability heuristic: with the Linda problem rational and educated people finding the likelihood of an event greater than that of a larger one that encompasses it. I am glad to be a trader taking advantage of people’s biases but I am scared of living in such a society. An Absurd World Kafka’s prophetic book, The Trial, about the plight of a man, Joseph K., who is arrested for a mysterious and unexplained reason, hit a spot as it was written before we heard of the methods of the “scientific” totalitarian regimes.

Risk and emotions: Given the growing recent interest in the emotional role in behavior, there has been a growing literature on the role of emotions in both risk bearing and risk avoidance: The “risk as feeling” theory: See Loewenstein, Weber, Hsee and Welch (2001), and Slovic, Finucane, Peters and MacGregor (2003a). For a survey, see Slovic, Finucane, Peters and MacGregor (2003b). See also Slovic (1987). For a discussion of the affect heuristic: See Finucane, Alhakami, Slovic and Johnson (2000). Emotions and cognition: For the effect of emotions on cognition, see LeDoux (2002). Availability heuristic (how easily things come to mind): Tversky and Kahneman (1973). Real incidence of catastrophes: For an insightful discussion, see Albouy (2002). On sayings and proverbs: Psychologists have long examined the gullibility of people in social settings facing well-sounding proverbs. For instance, experiments since the 1960s have been made where people are asked whether they believed that a proverb is right, while another cohort is presented the opposite meaning.

Availability How much should you worry about hurricanes, nuclear power, terrorism, mad cow disease, alligator attacks, or avian flu? And how much care should you take in avoiding risks associated with each? What, exactly, should you do to prevent the kinds of dangers that you face in ordinary life? In answering questions of this kind, most people use what is called the availability heuristic. They assess the likelihood of risks by asking how readily examples come to mind. If people can easily think of relevant examples, they are far more likely to be frightened and concerned than if they cannot. A risk that is familiar, like that associated with terrorism in the aftermath of 9/11, will be seen as more serious than a risk that is less familiar, like that associated with sunbathing or hotter summers.

Thus vivid and easily imagined causes of death (for example, tornadoes) often receive inflated estimates of probability, and less-vivid causes (for example, asthma attacks) receive low estimates, even if they occur with a far greater frequency (here a factor of twenty). So, too, recent events have a greater impact on our behavior, and on our fears, than earlier ones. In all these highly available examples, the Automatic System is keenly aware of the risk (perhaps too keenly), without having to resort to any tables of boring statistics. The availability heuristic helps to explain much risk-related behavior, including both public and private decisions to take precautions. Whether people buy insurance for natural disasters is greatly affected by recent experiences.6 In the aftermath of an earthquake, purchases of new earthquake insurance policies rise sharply—but purchases decline steadily from that point, as vivid memories recede.

A survey by the Harvard School of Public Health found that about 44 percent of college students engaged in binge drinking in the two-week period preceding the survey.16 This is, of course, a problem, but a clue to how to correct it lies in the fact that most students believe that alcohol abuse is far more pervasive than it actually is.17 Misperceptions of this kind result in part from the availability heuristic. Incidents of alcohol abuse are easily recalled, and the consequence is to inflate perceptions. College students are influenced by their beliefs about what other college students do, and hence alcohol abuse will inevitably increase if students have an exaggerated sense of how much other students are drinking.

. … When people formed opinions about crime in their local area, they were more reliant on their own experiences or the experiences of people in their communities. However, when people formed perceptions of crime across the whole country their main source of information was the media.11 Newspapers feed pessimism by triggering our availability heuristic, a well-studied mental shortcut or rule of thumb that makes people prone to irrationality by forcing them to recall a few immediate examples of any event. This makes them wrongly believe that such events are more widespread than they are. For example, the media typically reports airplane crashes, shark attacks, and mass shootings as front page events, which results in people remembering them in complete disproportion to the odds of their actually being involved in one.

Polling firm Ipsos MORI annually publishes the rather amusing Perils of Perception Index, which asks respondents in numerous countries their views on issues such as the murder rate or the number of terrorist attacks relative to the past, or the share of immigrant prisoners and teenage births.14 Countries tend to do particularly bad on issues that garner considerable media attention, which further highlights the massive impact of the availability heuristic on our political sentiments. For example, with anti-immigrant rhetoric at all-time highs it’s not surprising that Americans think immigrants compose a much larger share of the prison population: nearly a third according to the index. However, the number is just 5.2%. Likewise, large majorities of people in Turkey, the Philippines, India, and Colombia — some of the countries which have been most affected by domestic or international terrorism in the past couple of decades — all think terrorist deaths have increased or remained about the same since 9/11 when in fact they have declined, often considerably so.

Part of the problem is that an entire billion-dollar industry has been created to reinforce this delusion, as evidenced by the thousands of managerial and leadership books that are published each year (and which look and feel exactly like self-help books), leadership seminars led by self-appointed gurus who both look and speak like the corporate versions of televangelists, business reality shows, and the endless glorification of entrepreneurs in the media — especially the ones who have mastered the art of self-promotion regardless of merit (the now disgraced Elizabeth Holmes of over-hyped medical startup Theranos being a recent example).39 The undeserved adulation and reward that Western societies heap on their business elite undoubtedly has a terrible impact on these people’s egos, in no less a manner than it has on that of despots, which permanently impairs their capacity for accepting criticism and failure and leads to decisions based on mere hubris. The end result is for these leaders to fall for all the optimism biases that were explained in Chapter Two, and for the rest of us to fall for the availability heuristic if all the stories we hear about them are the good ones. All in all, the idea that business leaders are an enlightened elite of supermen (or occasionally superwomen40) makes for good cover stories and management biographies, but the reality is much less romantic: All too often flesh-and-blood leaders fall short.

Philip Tetlock reports that grandmasters at chess have 50,000–100,000 patterns stored in this deep memory system.2 But when we incorrectly see a familiar framing for a new kind of problem, we risk disastrously wrong solutions or endless work getting back on track. This kind of mistake is sometimes called an availability heuristic (you use the framework you happen to have handy, not the right one) or substitution bias (you substitute a simple model you know rather than understanding the more complicated actual model). And even when there is no absolute cognitive mistake in problem framing, excessive problem patterning is a block on novel solutions and creativity in problem solving.

If that’s the case, why is it so much easier to create a list of words that start with K? It turns out that our mind’s retrieval process is far from perfect and that a number of cognitive quirks play into our ability to recall information. Psychologists call this fallibility in your memory retrieval mechanism the availability heuristic, which simply means that we predict the likelihood of an event based on how easily we can call it to mind rather than how probable it is. Kahneman and Tversky first observed this effect in their 1973 paper where they noted that an information signal is salient (i.e., memorable) if it has characteristics that differ from the background or a past state.

Evidence of the usefulness of the WWW was everywhere, making it easy to create internal narratives about how the internet could be paradigm changing. Likewise, we see the effects of black swan events like the Great Recession linger in the public consciousness for years after the fact, unusual and impactful as they are. Unfortunately for us, the imperfections of the availability heuristic are hard at work as we attempt to gauge the riskiness of different ways of living and investing. The power of story The basic premise of the attention pillar is that we make probability-insensitive judgments because of our reliance on information that is vivid over information that is factually accurate.

The amount of space that people need increases predictably over time as they find partners and have children; it makes sense to buy early in order to protect themselves against the risk of future price increases that would make houses unaffordable. When prices start going up, another behavioral bias starts to kick in. The “availability heuristic” captures the propensity of people to assess situations by referring to examples that come readily to mind. A 2008 paper by Hugo Benitez-Silva, Selcuk Eren, Frank Heiland, and Sergi Jiménez-Martín used the Health and Retirement Study, a biennial survey of Americans over the age of fifty, to compare people’s estimates of the value of their homes with actual values when a sale took place.

Moreover, Americans often conflate the idea of an economic class structure with that of a caste structure; if there is any mobility, it is taken as evidence of a lack of the former.4 And indeed there is some minor fluidity between strata. Most people can think of at least one person they know (often from one or more generations ago) who rose to riches despite modest means or fell from positions of affluence. In line with what behavioral economists call the availability heuristic, we tend to overgeneralize from these familiar cases to believe that mobility is far more common (and possible) than it is.5 The reality is that in any class system, including ours, mobility happens.6 But the deck is stacked against it. Chances are that children will end up in the same economic quintile as their parents.7 Furthermore, studying economic elites tends to be problematic in the United States not only because of the types of ideological barriers noted above but also because, unlike the United Kingdom, for example, the United States lacks historic metrics for measuring relative class position.

Rather, decisions turn on interviewers’ subjective interpretations of interviews and candidates. Moreover, people typically draw from cognitive attributions and interpretations when making complex, high-stakes decisions and those where there is a sense of personal accountability (Leach and Tiedens 2004), such as in the hiring decisions analyzed here. 11. This is a subset of the availability heuristic. For a review of this and other cognitive biases in decision making, see Kahneman 2011. 12. Chen and Miller 2012; Duckworth et al. 2007. 13.

You’ll just have an uneasy feeling that taking a walk is dangerous—a feeling you would have trouble explaining to someone else. What System One did is apply a simple rule of thumb: If examples of something can be recalled easily, that thing must be common. Psychologists call this the “availability heuristic.” Obviously, System One is both brilliant and flawed. It is brilliant because the simple rules of thumb System One uses allow it to assess a situation and render a judgment in an instant—which is exactly what you need when you see a shadow move at the back of an alley and you don’t have the latest crime statistics handy.

Like the paper itself, the three rules of thumb it revealed were admirably simple and clear. The first—the Anchoring Rule—we’ve already discussed. The second is what psychologists call the “representativeness heuristic,” which I’ll call the Rule of Typical Things. And finally, there is the “availability heuristic,” or the Example Rule, which is by far the most important of the three in shaping our perceptions and reactions to risk. THE RULE OF TYPICAL THINGS Linda is thirty-one years old, single, outspoken, and very bright. She majored in philosophy. As a student, she was deeply concerned with issues of discrimination and social justice, and also participated in anti-nuclear demonstrations.

And it’s downright bizarre that people don’t rush to get insurance when scientists issue warnings. At least, it makes no sense to Head. To Gut, it makes perfect sense. One of Gut’s simplest rules of thumb is that the easier it is to recall examples of something, the more common that something must be. This is the “availability heuristic,” which I call the Example Rule. Kahneman and Tversky demonstrated the influence of the Example Rule in a typically elegant way. First, they asked a group of students to list as many words as they could think of that fit the form _ _ _ _ _ n _. The students had 60 seconds to work on the problem.

Dramatic and salient events of any kind stick in their minds, whereas they are apt to downplay everyday happenings. Since 9/11, for example, many Americans fret more about being killed in a terrorist attack than in a road accident, even though in advanced countries the latter outcome is roughly four hundred times more likely. Kahneman and Tversky refer to this sort of thing as the “availability heuristic.” When thinking about the dangers we face, getting blown up comes to mind more readily than getting run over: it is more available. Kahneman and Tversky also pointed out that people have a general inclination to judge things relative to arbitrary reference points. When the status quo is their reference point, people tend to assume that things won’t change very much—the bias of conservatism.

Hubris comes in many forms. Especially when the economy is doing well, businesses and individuals find it increasingly difficult to imagine that anything very bad could happen—a phenomenon known as “disaster myopia.” The representativeness heuristic obviously plays a role here, but so does the availability heuristic. By definition, low-probability events such as stock market crashes and credit crunches occur rarely, which means that many people don’t have any personal experience of them to draw on. After the 1981–82 recession, it was almost twenty years before the stock market underwent another lengthy downturn.

But Guttentag and Herring pointed out that the banks tend to underestimate the chances of a systemic shock that could render many of their lenders simultaneously unable to repay their loans, such as the American economy plunging into a deep recession, or a sovereign government defaulting on its loans. When the economy is growing strongly, such a possibility is difficult to imagine (the availability heuristic), and bankers downplay it. Eventually, the danger comes to be seen as so remote that it is ignored (the threshold heuristic), and banks take on too much lending exposure relative to their capital. Myopia is another mental trait that behavioral economists have examined. In the late 1990s and early 2000s, the U.S. personal savings rate fell sharply.

Musk has claimed that in developing AI technology, humanity is “summoning a demon,” and that smart machines are “our biggest existential threat” as a species. After you’ve read our book, you’ll be able to decide for yourself whether you think these worries are credible. We want to warn you up front, however, that it’s very easy to fall into a trap that cognitive scientists call the “availability heuristic”: the mental shortcut in which people evaluate the plausibility of a claim by relying on whatever immediate examples happen to pop into their minds. In the case of AI, those examples are mostly from science fiction, and they’re mostly evil—from the Terminator to the Borg to HAL 9000. We think that these sci-fi examples have a strong anchoring effect that makes many people view the “evil AI” narrative less skeptically than they should.

I wondered if the dog would go berserk and, if so, what would happen. The story affected my perception of risk. This is the same thinking that leads people to carry pepper spray after watching a lot of episodes of Law & Order: SVU or to check the back seat of the car for nasty surprises after watching a horror movie. The technical name is the availability heuristic.15 The stories that spring to mind first are the ones we tend to think are the most important or occur most frequently. Perhaps because it features so prominently in our collective imagination, the Titanic disaster is commonly used for teaching machine learning. Specifically, a list of the passengers on the Titanic is used to teach students how to generate predictions using data.

In a previous study on a campus parking lot—a lot that was crowded but usually had some spaces in the back rows—Velkey polled students about how long they thought it typically took them to find a parking space. “They said four and a half minutes,” Velkey told me. “In reality, when we watched them, it takes about thirty seconds. I said, ‘Where did that extra four minutes come from?’” Velkey suggests that the psychological principle known as the “availability heuristic” was at work. Students were tending to remember the few times when it was very difficult to find a spot, instead of the everyday experience in which it was quite easy. They were remembering the things that stuck out in their memory. In the Wal-Mart lot, there was something else interesting about the two groups of parkers.

Kobza, “A Probabilistic Approach to Evaluate Strategies for Selecting a Parking Space,” Transportation Science, vol. 32, no. 1 (January 1998), pp. 30–42. to walk somewhere: Travel Behaviour Research Baseline Survey 2004: Sustainable Travel Demonstration Towns (SUSTRANS and Socialdata, 2004). Retrieved from http://www.sustrans.org.uk/webfiles/travelsmart/STDT%20Research%20FINAL.pdf. was at work: The “availability heuristic” is credited to Daniel Kahneman and Amos Tversky. (Heuristic is a sophisticated-sounding word that really just means “mental shortcut.”) When people are asked to imagine how often something happens, they tend to overestimate the probability of things that can be more easily recalled from memory—that is, that are “available”—or that loom more vividly in the imagination.

responsibility in the crash: Daniel Blower, “The Relative Contribution of Truck Drivers and Passenger Vehicles to Truck-Passenger Vehicle Traffic Crashes,” report prepared for the U.S. Department of Transportation, Federal Highway Administration, Office of Motor Carriers, June 1998. is actually the case): This may be the “availability heuristic” at work again. Large trucks, in part because they are driven longer distances and tend to be on the road at the same time as most motorists, seem to be more prevalent than they really are. A Canadian study found that while motorists believed that the number of trucks on the roads was rising, the number actually dropped during the period in question (while the number of cars grew).

Most people think the same. But actually, you’re in for a surprise. All of these estimates are wrong. Some of them by miles. Now ask yourself this. Of the kinds of fatality just described, which do you hear most about? Which are the most ‘available’ in your memory? 13It’s difficult to convey the power of the availability heuristic without a concrete example. So let’s take a look at one right now. Below is a list of names. Read them over carefully, and then as soon as you’ve done so cover them up with a sheet of paper: OK. Now that you’ve read the names try to recall as many of them as you can. Then estimate whether there were more women on the list, or men.

It says: you are of value to me, rather than the other way round. And they think – why would I be of value to him? He’s already got everything he needs. He must really like me.’ Though on the surface mundane, what Khan does with his hands is actually quite intoxicating. For brown nosers, both representativeness and availability heuristics involve people of lower status sucking up to those of higher status. But confound that expectation, chuck in a bit of antithesis – switch on the hazard signs on those super-fast cognitive expressways – and suddenly, dramatically, we have to slam on the brakes. We have to make sense of the snarl-up. 14Psychologist David Strohmetz and his colleagues at Monmouth University have demonstrated a principle very similar to the one Khan uses.

(Consider also that Watson is a bachelor, just returned from war, wounded, and largely friendless. What would his chronic motivational state likely be? Now, imagine he’d been instead married, successful, the toast of the town. Replay his evaluation of Mary accordingly.) This tendency is a common and powerful one, known as the availability heuristic: we use what is available to the mind at any given point in time. And the easier it is to recall, the more confident we are in its applicability and truth. In one of the classic demonstrations of the effect, individuals who had read unfamiliar names in the context of a passage later judged those names as famous—based simply on the ease with which they could recall them—and were subsequently more confident in the accuracy of their judgments.

The floods in 1993 were much more severe than anything previously experienced. There should have been an update in the belief of residents there about the severity of future floods, a factor that would certainly affect housing values.5 Two subject areas in behavioral economics, prospect theory and the availability heuristic, help explain the over-updating of virgin risks and the under-updating of experienced risks after an extreme event. A finding of prospect theory is that individuals place excess weight on zero. The Russian Roulette problem illustrates this phenomenon. Most people are willing to pay more to remove one bullet from a six-cylinder gun when it is the only bullet than if there are two (or more) bullets in the gun.

The theory of just noticeable differences explores such phenomena. For instance, as a noise gets louder, a greater change in volume is needed to make the change perceptible. This is similar to our argument that as base probabilities get larger, small changes in probability are not perceived as well. The availability heuristic also supports our conjecture. It asserts that individuals assess the probability of an event as higher when examples come to mind more readily. Once an event has occurred, it is much more salient, leading individuals to overestimate its probability. While the first occurrence of a risk makes it suddenly salient, the third occurrence, say, does not add much to its availability.

High earners may truly believe that they deserve their income because they are vividly aware of how hard they have worked and the obstacles they have had to overcome to be successful. Unfortunately, our memories play tricks, systematically biasing the narrative of the path to success that we construct. The biggest culprit is probably the availability heuristic (another one of Kahneman and Tversky’s major insights). When English speakers are asked whether English words beginning with the letter K are more frequent than words with K as the third letter, most choose the former. In fact, there are more words with K as the third letter, but words beginning with K are much more available to our minds because it is easier to think of examples.

According to a major study by marketing psychologists Ezgi Akpinar and Jonah Berger, who combined controlled laboratory experiments with systematic analysis of hundreds of online ads, it is clear that “emotional appeals (which use drama, mood, music, and other emotion-eliciting strategies) are more likely to be shared” than “informative appeals (which focus on product features).”155 As attention merchants have known for decades, emotional appeals sell better than rational ones. Social media’s flood of content also amplifies other cognitive biases in ways that uniquely allow false information to root itself in the public consciousness.156 Consider “the availability heuristic” and “the illusory truth effect” — terms describing cognitive traits that explain how collective beliefs are reinforced regardless of their veracity or merit, as a result of their repetition.157 Social psychology experiments have demonstrated that repeated exposure to information increases the likelihood that observers will believe that information, even if it is false.

Inside the Nudge Unit: How Small Changes Can Make a Big Difference by David Halpern

Rather, most people use a mental shortcut along the lines of how easily they can recall examples of planes versus cars crashing – what Tversky and Kahneman called an ‘availability’ heuristic. The more easily the person can call to mind an example, the more likely or common they infer it to be. It’s generally not a bad heuristic. It gives you a pretty good idea of how many tigers versus pigeons you might meet walking around the streets of London or New York. But when it comes to aeroplane versus car safety, using the availability heuristic can lead us badly astray. Rare but devastating air crashes make the news and stick in our minds, but the daily death toll on our roads passes largely without comment or lasting attention.

The concept of availability chambers harkens to availability cascade, which is a self-reinforcing process of collective belief formation. Under an availability cascade, an expressed perception triggers a chain reaction that gives that perception increasing plausibility through its rising availability in public discourse.22 The process is intermediated by the availability heuristic, a pervasive mental shortcut through which the perceived likelihood of any given event depends on the ease with which its occurrences can be brought to mind. Cognitive psychologists find that individual beliefs regarding truth and falsehood are generally based on the ease with which pertinent examples come to mind.

Behavioral psychology has identified two more reasons why we neglect existential risk, rooted in the heuristics and biases we use as shortcuts for making decisions in a complex world.62 The first of these is the availability heuristic. This is a tendency for people to estimate the likelihood of events based on their ability to recall examples. This stirs strong feelings about avoiding repeats of recent tragedies (especially those that are vivid or widely reported). But it means we often underweight events which are rare enough that they haven’t occurred in our lifetimes, or which are without precedent. Even when experts estimate a significant probability for an unprecedented event, we have great difficulty believing it until we see it. For many risks, the availability heuristic is a decent guide, allowing us to build up methods for managing the risk through trial and error.

Is K more likely to appear as the first letter in a word or as the third letter?’ 15 According to Kahneman, most people wrongly respond that K appears more often as the first letter. It is easier to think of words that begin with a particular letter than to acknowledge words that have that letter in the third position. Kahneman and Tversky christened this the ‘availability heuristic’. It uses the simplest memory search to come up with an answer. But the experiment did not provide any serious motivation for answering the question, or even for defining properly the question being asked. Most people might reasonably answer ‘I don’t know, but if it is important I will try to find out’.

'R' appears in the third-letter position of more English words than in the first-letter position, yet it is much easier to recall words that begin with ' R' than words whose third letter is 'R'. Thus, a majority of respondents guess that words beginning with 'R' are more frequent, when the reverse is the case (Tversky and Kahneman, 1973). Biases implicit in the availability heuristic affect estimates of risk. A pioneering study by Lichtenstein et al. ( 1 978) examined absolute and relative probability judgements of risk. People know in general terms which risks cause large numbers of deaths and which cause few deaths. However, asked to quantify risks more precisely, people severely overestimate the frequency of rare causes of death and severely underestimate the frequency of common causes of death.

The idea that a repeated pattern, such as a roulette wheel coming up black, must at some point be reversed is very common – even though the wheel of course has no memory of the past. The same bias can explain why investors buy into falling share prices on the expectation that at some point at least they must rise. Chapter 10 • Daniel Kahneman225 The availability heuristic in turn leads to biases, including the retrievability, imaginability and illusory correlation biases. Events that are easy to recall or which readily spring to mind – and so can easily be ‘retrieved’ – are more likely to be used by someone making a quick decision than information that would have to be researched.

The market was euphoric (India’s Nifty index went up 7× between 2003 and 2007), and liquidity dried up completely (credit markets froze after the collapse of Lehman Brothers). How can excessive booms and busts take place so frequently in an efficient market whose primary foundation is rooted in the combined assumptions of utility-maximizing behavior, market equilibrium, and stable preferences? The answer is found in what Daniel Kahneman describes as the “availability heuristic” (one of the most insidious and potent cognitive biases): People tend to assess the relative importance of issues by the ease with which they are retrieved from memory—and this is largely determined by the extent of coverage in the media. Frequently mentioned topics populate the mind even as others slip away from awareness.

When something bad happens anywhere, two billion smartphones will nowadays make sure that we find out, even if no reporters are on the scene. The psychologists Daniel Kahneman and Amos Tversky have shown that people do not base their estimates of how frequent something is on data, but on how easy it is to recall examples from memory.16 This ‘availability heuristic’ means that the more memorable an incident is, the more probable we think it is, so we imagine that horrible and shocking things, which stay in our thoughts, are more frequent than they are. We are probably built to be worried. We are interested in exceptions. We notice the new things, the strange and unexpected.

But unavoidable mistakes have been demonstrated in test after test, and given names like anchor bias (you want to stick to your first estimate, or to what you have been told), ease of representation (you think an explanation you can understand is more likely to be true than one you can’t). On and on it goes— online there is an excellent circular graphic display of cognitive errors— a wheel of mistakes that both lists them and organizes them into categories, including the law of small numbers, neglect of base rates, the availability heuristic, asymmetrical similarity, probability illusions, choice framing, context segregation, gain/loss asymmetry, conjunction effects, the law of typicality, misplaced causality, cause/effect asymmetry, the certainty effect, irrational prudence, the tyranny of sunk costs, illusory correlations, and unwarranted overconfidence— the graphic itself being a funny example of this last phenomenon, in that it pretends to know how we think and what would be normal.

The big banner with the Keeling Curve stretching across it, with its continuous rise, then the leveling, then the recent downturn, stood over everything else like a flag. And under that, there was so much going on that she had never heard of. She felt again the power of the cognitive error called the availability heuristic, in which you feel that what is real is what you know. But there was so much more going on than any one person could know, reality was so much bigger than the self, that it was alarming to contemplate. This explained the error: one felt the vastness and shrunk in on oneself like a snail’s horns, instinctively trying to protect one’s mind.

If the “law of the jungle” means anything, it means collaboration for the most part, with a few perceptional distortions caused by our otherwise well-functioning risk-management intuitions. Even predators end up in some type of arrangement with their prey. HISTORY SEEN FROM THE EMERGENCY ROOM History is largely peace punctuated by wars, rather than wars punctuated by peace. The problem is that we humans are prone to the availability heuristic, by which the salient is mistaken for the statistical, and the conspicuous and emotional effect of an event makes us think it is occurring more regularly than in reality. This helps us to be prudent and careful in daily life, forcing us to add an extra layer of protection, but it does not help with scholarship.

The question was then altered such that no information was conveyed about the individual’s personality, and the subjects used the underlying probabilities properly. The example illustrates that when no specific, representative evidence is given, we use the prior probabilities correctly, but when worthless representative evidence is given, we tend to ignore the prior probabilities and become distracted by the representative evidence. The availability heuristic leads us to consider only those things that can be brought to mind with ease, often because we have personal experience with them. For example, we assess the risk of heart attack among middle-aged people by recalling such occurrences among our acquaintances, rather than by considering the underlying probabilities.

Kahneman and Tversky went on in the paper to describe how our vulnerability to representativeness also means we often make mistakes about the nature of chance, the effects of sample size, whether we have reliable information, and whether something can be predicted at all. They fundamentally destabilized our self-image as a rational species. And that was just the fourth page of the paper. Next, they turned to the availability heuristic, in which “people assess the frequency of a class or the probability of an event by the ease with which instances of occurrences can be brought to mind.” Our ability to remember something alters how common we consider that thing to be. Why is that a problem? “Availability”—our ability to think of an example—“is affected by factors other than frequency and probability,” they wrote.

Seeing the original price anchors your perception of what is an acceptable price to pay, meaning that you will go above your initial budget. If, on the other hand, you had not seen the original price, you would have probably considered it too expensive, and moved on. You may also have been prey to the availability heuristic, which causes us to over-estimate certain risks based on how easily the dangers come to mind, thanks to their vividness. It’s the reason that many people are more worried about flying than driving – because reports of plane crashes are often so much more emotive, despite the fact that it is actually far more dangerous to step into a car.

They tested for five letters (k, l, n, r, and v) like this. It is easier for people to think of words by first letter because we are taught to organize (or alphabetize) words by their first letter. However, people conflate this ease of recall with frequency or probability, even when this is far from the truth. This cognitive bias is called the availability heuristic, and is just one of many biases that affect our thinking. The bias is why, for example, people who see more news reports of violent murders on the news tend to think that society is becoming more violent when in fact global murder rates have been declining overall during the last quarter century.

So the death count of a war in 1600, for instance, would have to be multiplied by 4.5 for us to compare its destructiveness to those in the middle of the 20th century.9 The second illusion is historical myopia: the closer an era is to our vantage point in the present, the more details we can make out. Historical myopia can afflict both common sense and professional history. The cognitive psychologists Amos Tversky and Daniel Kahneman have shown that people intuitively estimate relative frequency using a shortcut called the availability heuristic: the easier it is to recall examples of an event, the more probable people think it is.10 People, for example, overestimate the likelihoods of the kinds of accidents that make headlines, such as plane crashes, shark attacks, and terrorist bombings, and they underestimate those that pile up unremarked, like electrocutions, falls, and drownings.11 When we are judging the density of killings in different centuries, anyone who doesn’t consult the numbers is apt to overweight the conflicts that are most recent, most studied, or most sermonized.

This is called the illusion-of-truth effect. You believe to be true what you hear often. The same applies to whatever comes to mind first or most easily. People, including you, believe the examples they can think of right away to be most representative and therefore indicative of the truth. This is called the availability heuristic. Let me give you a famous example. In English, what is the relative proportion of words that start with the letter K versus words that have the letter K in third position? The reason most people believe the former to be more common than the latter is that they can easily remember a lot of words that start with a K but few that have a K in the third position.

” • • • Which is more common, words that begin with r (like “road”) or words with r as the third letter (like “car”)? Most say that words beginning with r are more common. It’s easy to rattle off words beginning with r; harder and slower to free-associate words with r in third place. This is an example of the availability heuristic, and here it leads us astray. Words with r in third place happen to be more common. But because words beginning with r are more mentally available, we overrate how common they are. A familiar example of availability is the way we all assume that the tastes, politics, education level, and TV viewing habits of our social set are widely shared.

It took another fifty years before the notoriously conservative Lords of the Admiralty issued an order that made drinking lemon, and later lime, juice—hence “limeys”—compulsory for sailors on long voyages. * In the taxonomy of cognitive science, these are known, respectively, as anchoring, the availability heuristic, and confirmation bias. * Not everyone was as punctilious about ethics as the Tuberculosis Trials Committee. At the moment in 1947 when the war crimes tribunal convicted seventeen of the twenty-three defendants in the so-called Doctors’ Trial and published the ten-point Nuremberg Code for human experimentation, the infamous Tuskegee syphilis experiments had already been under way for fifteen years, and would continue observing the course of untreated syphilis in African American men for another twenty-five years

Monthly parking functioned like a gym membership, one of those sunk costs workers felt guilty for not making the most of every day. * * * — Even if parking is a kind of narcotic that creates its own demand, we mostly managed to build enough parking. So why does parking feel scarce? Part of the explanation may be what psychologists call the availability heuristic: It’s easy to recall the anxiety of being unable to park. It’s a terrible feeling to be trapped behind the wheel, especially when you have to pee. It’s also easy to remember finding a great spot on a crowded block. But when parking is easy, it is as thoughtless an experience as you can have behind the wheel.

It is a good essay on critical thinking and the dangers of lazy analysis. For example, he considers the question A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost?. Most people say 10 cents which is, of course, wrong. Muehlhauser notes that due to the availability heuristic, your brain will tell you that an AGI wiping out mankind is incredibly unlikely because you’ve never encountered this before. He also notes that extraordinary claims require extraordinary evidence. One point Muehlhauser refutes is that people that write about AGI are merely atheists whose fear of nihilism make them seek a moral purpose to save the world and fall for the seduction of Singularitarianism.

Perhaps the machinery is evolutionarily optimized to purposes that actively oppose epistemic accuracy; for example, the machinery to win arguments in adaptive political contexts. Or the selection pressure ran skew to epistemic accuracy; for example, believing what others believe, to get along socially. Or, in the classic heuristic-and-bias, the machinery operates by an identifiable algorithm that does some useful work but also produces systematic errors: the availability heuristic is not itself a bias, but it gives rise to identifiable, compactly describable biases. Our brains are doing something wrong, and after a lot of experimentation and/or heavy thinking, someone identifies the problem in a fashion that System 2 can comprehend; then we call it a “bias.” Even if we can do no better for knowing, it is still a failure that arises, in an identifiable fashion, from a particular kind of cognitive machinery—not from having too little machinery, but from the machinery’s shape.

While I am not averse (as you can see) to discussing definitions, we should remember that is not our primary goal. We are here to pursue the great human quest for truth: for we have desperate need of the knowledge, and besides, we’re curious. To this end let us strive to overcome whatever obstacles lie in our way, whether we call them “biases” or not. * 5 Availability The availability heuristic is judging the frequency or probability of an event by the ease with which examples of the event come to mind. A famous 1978 study by Lichtenstein, Slovic, Fischhoff, Layman, and Combs, “Judged Frequency of Lethal Events,” studied errors in quantifying the severity of risks, or judging which of two dangers occurred more frequently.1 Subjects thought that accidents caused about as many deaths as disease; thought that homicide was a more frequent cause of death than suicide.

A neighboring flaw is the logical fallacy of arguing from imaginary evidence: “Well, if you did go to the end of the rainbow, you would find a pot of gold—which just proves my point!” (Updating on evidence predicted, but not observed, is the mathematical mirror image of hindsight bias.) The brain has many mechanisms for generalizing from observation, not just the availability heuristic. You see three zebras, you form the category “zebra,” and this category embodies an automatic perceptual inference. Horse-shaped creatures with white and black stripes are classified as “Zebras,” therefore they are fast and good to eat; they are expected to be similar to other zebras observed.

I’m forgetting the name, shit. It’s the one where you think what you see is all of what’s going on. A very elementary cognitive error.” “Ease of representation,” Jeff says. “It’s an availability heuristic. You think what you see is the totality.” “That’s right, that’s the one.” Mutt acknowledges this, but says, “On the other hand, we do have quite a crew here.” Charlotte says, “Everybody does. There are two thousand people living in this building, and you only know twenty of them, and I only know a couple hundred, and so we think they’re the important ones.

Empirically we observe that various risk factors’ ex ante excess returns seem to be higher for a long while after a large negative factor shock. This pattern could reflect time-varying risk premia (the perceived amount and/or price of risk is high) or rational learning from the past but it is also suggestive of behavioral memory biases. Our probability assessments are distorted by the availability heuristic in that we tend to overweight strong signals, salient (vivid, emotion-triggering) events, and recent events. Memories decay only gradually after a major event; this fact might cause attractive reward-to-risk ratios to linger for surprisingly long periods. Famously, the ex ante equity premium remained high for over 20 years after the Great Depression (whereas investor memories were shorter after the 2000–2002 and 2007–2009 bear markets).
