how to avoid availability heuristic

So how much of your emotionsmight influence your decision-making and what impact might it have on your life? But imagine trying to outswim a hungry shark and your palms start to sweat. What’s clear is that managers relied on the ease with which they could remember as a shortcut for judging how happy they were, while subordinates relied on the actual content of the experiences themselves to judge how happy they were. But this wasn’t the case with the auto mechanics—the experts. As time passed, memories of the same experiences became more positive.[37]. So far, we have shown how the availability heuristic is the shortcut that confuses easy with true. [21] Kahneman, D. (2011). Stroke causes 85% more deaths than accidents, but only 20% of students and 23% of the general population thought stroke was more likely than accidents at all. You rely on the ease with which something comes to mind instead of the content of what comes to mind when making a decision. Thinking, Fast and Slow. Willingness to pay goes up when descriptions of those risks are emotional, even if the probability doesn’t change. “The psychological impact of negative TV news bulletins: The catastrophizing of personal worries.” British Journal of Psychology, 88(1), 85-91. One study found that a flood results in an 8% increase of insurance policies above normal that same year. Two psychologists have found that people who have more than the average number of Facebook friends rely on the availability heuristic when they compare themselves to their friends, and as a result, they believe their friends are happier and have better lives than they do. (2008), “When Subjective Experiences Matter: Power Increases Reliance on the Ease of Retrieval.” Journal of Personality and Social Psychology, Vol 94(6), June 2008, 956-970. And as time passes, the glass becomes even fuller. It’s easy for anyone to think of two things, expert or not. [21], This was found to be true in a study on views of public transportation. Negative events leave a stronger impression and are easier to remember. [9] Regier, D. A., W. E. Narrow, D. S. Rae, R. W. Manderscheid, B. As a result, an additional 2,170 people who would have otherwise flown lost their lives in car accidents. Experts don’t have the same problem. Only you remember. One psychologist found that when people were asked to guess the frequency of the occurrence of letters in a set of words, the guesses correlated at .79 with the actual frequency. Enlightenment Now: The Case for Reason, Science, Humanism, and Progress. Savvy investors correctly predicted that the earthquake would cause people to temporarily purchase earthquake insurance, which would more than offset the costs of the insurance payouts.[7]). [37] Walker, W., Vogl, R., & Thompson, C. (1997). So that’s a hour waiting for the kettle. Here’s another way to look at it. What is the animal that I speak of? It’s a skewed sample; you’ll rarely see neutral or negative representations of your friends’ lives. Second, you’ll put together a story or scenario that may lead to divorce—something she said, something he did. Never mind that in the previous twenty years I’ve flown through Minneapolis nearly a hundred times without incident.). (I’ve avoided flying through Minneapolis this year for the sole reason that I spent last Christmas Eve there, and I don’t want to repeat that experience. What do these experiences have in common? Or, did they perceive themselves as the kind of people who ate out a lot? Real Life Examples of the Availability Heuristic. If I asked you, the assertive person, holding a list of examples of assertive behavior, if you really are an assertive person, you would be more likely to say no. In a twisted way, being happy makes us more susceptible to the ease-of-recall bias, and this bias predisposes us to recall negative events over positive events—which changes our mood from happy to sad. “There Are Many Reasons to Drive a BMW: Does Imagined Ease of Argument Generation Influence Attitudes?” Journal of Consumer Research vol. Session Goals •Recognize cognitive biases that influence your thinking and decision making •Learn how to overcome these biases in order to make better decisions or complete stronger analysis [31] Baumeister, R., Bratslavsky, E., Finkenauer, C., &Vohs, K. (2001). They would also have added the lack of tea bags. I have about 6 cups of tea a day. 4, 2012. Football is the ultimate sport of emotion. Avoid the potential for escalation or further emotional investment in faulty decisions engendered by premature “public” commitment. People also thought tornados killed more people than asthma attacks, even though asthma attacks kill 20 times more people than tornadoes every year. It’s part of human nature. It’s not the actual arguments that make people disagree, it’s the fact that producing them is hard. It’s the kind of thing that makes you decide not to go to the beach, or stay out of the water once you get there. Your brain needs to process more data than it can handle. You give greater credence to this information and tend to overestimate the probability and likelihood of similar things happening in the future. If you pay for flood insurance year after year without experiencing a flood, you’ll question whether flood insurance is a necessary expense. (1996). “Was it long ago or unimportant? Availability Heuristic . New York, NY: Viking. These examples—the positions of letters in words, a prediction about a hypothetical couple—are interesting thought exercises that reveal a quirk in our cognitive processes. Arsenic increases cancer risk. [28] Hansen and Hansen (1988). In particular, we use this for judging frequency or likelihood of events. New York: Psychology Press. Even though negative events have an outsized impact as they are experienced, they have a diminished impact as they are remembered. In this case, your guess at the overall frequency in the last month will be influenced by how often you’ve driven in the past week compared to how often you drove four weeks ago. When you are trying to make a decision, a number of related events or situations might immediately spring to the forefront of your thoughts. Shark attacks are more vivid and more likely to affect your behavior, even though riptides may be just as likely to kill you.[40]. [36] Baumeister, R., Bratslavsky, E., Finkenauer, C., &Vohs, K. (2001). It seemed like the most important thing to be focused on at that time. [10] Regier, D. A., W. E. Narrow, D. S. Rae, R. W. Manderscheid, B. 24. The first is to be aware of—and avoid—the conditions that make you more likely to rely on the availability heuristic. This is the availability heuristic, “We make a judgement based on what we can remember, rather than complete data because we remember recent experiences or reports, then the news has a significant effect on our decisions.”. However, statistics show that you are as much as 10x more likely to meet your end while working on a fishing boat . But when they were asked to produce many reasons why their car wouldn’t start, they found it difficult. The availability heuristic simply refers to a specific mental shortcut: what comes to mind the easiest—what’s most available—is true. People remember more negative things than positive things in the short term. ( Log Out /  Second, they were to give a ratio to indicate how much more likely one cause was over the other. But offline, real-world interactions with your friends contain no such selection bias. By the second year, this drops to 49.5%. You get the wrong impression, because pictures of people on the beach have a disproportionate influence on your perception of how everyone else is spending spring break. Enlightenment Now: The Case for Reason, Science, Humanism, and Progress. [27] Lichtenstein, Slovic, Fischhoff, Layman, & Combs, 1978. “Judged frequency of lethal events.” Journal of Experimental Psychology: Human Learning and Memory, 4 (6), 551–578. First, they were to estimate which of the two causes of death was more likely. Let’s take a look at why each of these conditions leads you to rely on ease-of-recall and make you more likely to use the availability heuristic. How to avoid availability heuristic? You can also provoke a shark and expect a response. When you have a good day, this doesn’t affect how you feel the following day. [4] Michel-Kerjan, E., de Forges, S., and Kunreuther, H. (2012). They get you from point A to point B more quickly. This trend—the belief that violence is increasing, even as the world becomes safer—is covered in exhausting detail by Steven Pinker in his excellent book, The Better Angels of Our Nature: Why Violence Has Declined. Due to the availability heuristic, we favor information that is easily understood and recalled. “How to dispel your illusions.” New York Review of Books. As a result, you are more likely to make bad decisions, miscalculate and overreact to risks, hold inaccurate perceptions about yourself and others, and behave in ways that aren’t in your best interests. “The availability heuristic in the classroom: How soliciting more criticism can boost your course Those who gave seven reasons to use public transportation reported more negative views of public transportation than those who gave three reasons.[22]. There are two ways. In general, availability is correlated with ecological … Ask for an opinion, an outside view. That’s because everything about how we experience the world seems to point to one thing: that things are bad and getting worse. A heuristicis a word from the Greek meaning “to discover.” It is an approach to problem solving that takes one’s personal experience into account. In neither actual—comparing this couple to other couples, and coming up with a story—are you using actual data to make your prediction. According to a 2011 Gallup poll, 68% of people say there is more crime this year than last year and that crime is getting worse. Should you worry about arsenic levels in your drinking water? [17] Johnston, W. M., & Davey, G. C. (1997). In perhaps the oddest example of the effect of the availability heuristic on a company’s stock performance is the Anne Hathaway effect. I would ask you to tell me about times you acted assertively, and you would have no problem coming up with a long list. And students as a whole thought accidents were 25 times more likely than strokes. [36], Additionally, people’s memory of a negative event becomes less negative over time at a fairly measurable rate. The relationship between marital processes and marital outcomes. We did not recall the problem with the slow kettle as this was not the most readily available in our minds whereas the disaster of the tea bags was. For a water district with a million households, the new standards cost 86¢ per household per year. [45] Ruder, M. and Bless, H. (2003). This causes unnecessary stress. Avoiding Availability Heuristic Lets look back at our availability heuristic example. It’s part of human nature. But sometimes they cause real harm. 3, pp. 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. “Ease of Recall vs Recalled Evidence in Judgment: Experts vs Laymen.” Organizational Behavior and Human Decision Processes 81(1), 28–42. One professor who tried this found that students who offered more criticism rated the course 12% more positively than everyone else. Because easy equals true and hard equals false, the difficulty of thinking of negative feedback will cause students to discount the actual content of the negative feedback. In another one of Tversky and Kahneman’s thought experiments, they asked people to guess the likelihood of an imaginary couple getting a divorce. We are more likely to notice a threatening face in a crowd of people than a neutral or positive face. Because it’s easier and scarier to imagine being killed by a shark than a coconut, death-by-shark comes to mind more easily than death-by-coconut, so it’s more likely to affect your behavior. [39] Here are the results: You would expect that when arsenic risks went up by a factor of ten, willingness to pay to eliminate those risks would go up by the same amount. I initially came across the idea on Kevin E. Schlabach’s blog post: Snake on the Wall, […] If you would like to read more about this topic, please click here […], […] https://agiletestinglessonslearned.wordpress.com/2014/02/04/avoiding-the-availability-heuristic-more… […], […] Avoiding the Availability Heuristic Written by: Mary Walshe […]. If you were an assertive person, it would be easy to think of examples of your assertiveness. People who were not distracted remembered 9.44 of the 15 words, and it took them 420 milliseconds to retrieve each word from memory. Availability Heuristic. But when people were multitasking during retrieval, performance dropped. You’re less likely to rely on the availability heuristic. These results are similar to the experience earlier about assertive people who produced many examples of assertive behavior perceived themselves to be less assertive than people who produced only a few examples of assertive behavior. [19] Schwarz, N., Bless, H., Strack, F. Simons, A. Our brain is wired to find the optimal balance between speed and accuracy, which means you’ll never be able to completely overcome the availability heuristic. Representativeness bias is the reason why people create stereotypes. Happy or sad, thinking of ten arguments is more difficult. This drives up medical costs for themselves and others. Because words where k is the first letter come to mind more easily than words where k is the third letter, and because you are more likely to believe things that come to mind easily are true, you get it wrong. When estimating the size of a category, like “dangerous animals,” if it’s easy to retrieve items for a category, you’ll judge the category to be large. [13], Product recalls have the same effect. 17, No. Boulder, Colorado: Westview Press, 111. A team of British psychologists found heavy news consumption “raised self-reported measures of anxious and sad mood, and subsequently led to the enhanced catastrophizing of personal worries,” and “it can exacerbate a range of personal concerns.”[17] When people devote outsized attention to what’s most available, they come stressed, worried, indifferent, or apathetic. It’s easy to think of violent acts we’ve experienced ourselves or seen on the news. But what makes something easy? “The effects of divided attention on encoding and retrieval processes in human memory.” Journal of Experimental Psychology 125(2), 159–180. Negative interactions have an effect five times stronger than positive interactions. Your perceived frequency is based on how easily instances of words that start with k come to mind compared to words where k is in the third position. At the same time, we should acknowledge that even though our frequency isn’t perfect, it’s actually not too bad, either. When non-experts were asked to think of a few reasons why their car wouldn’t start, they had little difficulty. [26] (Think of correlation on a scale of -1 to 1, with 1 being perfect correlation.). [7] Shelor, R., Anderson, D., and Cross, M. (1992). But people in power “reported a more favorable attitude toward sending humans to Mars after generating few as opposed to many arguments.”[44]. Those who could think of lots of examples of riding their bikes believed they rode infrequently. If a tornado barrels through your town next year, the tornado doesn’t remember that a different tornado did the same thing last year, or two years ago, or ten years ago. ( Log Out /  Yesterday there was no tea bags and none of us could have tea. Your times been wasted today? This makes sense if you think about it: If it’s so hard to think of negative feedback, this must be a pretty great course. An example would be the ease with which relevant instances come to mind. There are more pigeons than orioles in urban areas. Change ), You are commenting using your Google account. Once again, you can make a good guess, but you’re probably not quite as sure. In the experiment that proved this, people’s perception of how assertive they perceived themselves was directly correlated with how difficult it was to think of examples of assertive behavior.[19]. That’s because the product category—not just a single company’s product recall—becomes more available in the mind of both consumers who buy that kind of product and in the minds of investors who buy the company’s stock.[14]. “Bad is stronger than good.” Review of General Psychology, Vol 5(4), Dec 2001, 323-370. Or you’ll remember the time you slept on the floor because you couldn’t get a flight until the next morning. But if you’re making a judgment about the more distant past, positive events will come to mind more easily. How do we avoid falling for the availability heuristic? People also thought botulism and asthma kill roughly the same number of people each year, even though asthma kills 900 times more people. But when you’re not an expert, you’ll have a limited number of available instances, which will make recall more difficult. People who are asked to give many reasons for a choice they have made instead of a few reasons tend to be less confident in the choice they have made. But by the tenth year, the number of insurance policies returns to the normal, predicted amount. The data most available to him was cold temperatures, not all temperatures averaged out. Frequent ads for antidepressants cause you to believe you have a high risk of becoming depressed. In an experiment, researchers split people into two groups. For water districts with 500 households, the costs rose to $163 each. When you scroll through your newsfeed, you only see others’ positive representations of themselves. In others, not. However, when people are exposed to frequent ads to antidepressants, they estimate that 38% of adults experience depression each year. “Availability: A Heuristic for Judging Frequency and Probability.” Cognitive Psychology 5, 207–232. Even Hurricane Katrina didn’t change the average policy length over the long term. If it’s easy to remember a flood, you’ll buy insurance, because it seems floods occur rather often. We all talked about the tea bags running out how it effected us and what we were going to do to prevent it in the future. But recalling two events in the distant past is barely easier than recalling ten events in the distant past, which means the easy-it-true bias doesn’t have the same effect. 48, 435–449. Z. Locke and F. K. Goodwin: 1993, “Epidemiologic Catchment Area Prospective 1-Year Prevalence Rates of Disorders and Services,” Archives of General Psychiatry 50(2), 85–94. What you won’t see is that most of your friends are stuck in Michigan, just like you are. So if your brain is performing a recall task while doing something else, even though your recall will suffer (by 12.9%, it seems), the something else you’re doing will suffer even more.[41]. . Think up some possible problems is easier for a non-expert than an expert. When it’s easy to come up with a list of assertive behavior–i.e. 3, pp. Availability bias describes the way in which human beings are biased toward judging events’ likelihood/frequency based on how easily their minds can conjure up examples of the event occurring in the past. [6] Gallagher (2014). The way it does this is by taking mental shortcuts that are reliable most of the time, but not all of the time. (1994). The world is a safer, more peaceful place than it ever has been. Description. With betting however it is important to think in long-term patterns , and ignore short-term form to a certain degree. For example, if they thought dying in a car accident was more likely than from a car accident, then the ratio might be three-to-one: three people die in car accidents for every one person killed by lightning. People thought death by lightning was unlikely compared to death from botulism, even though 52 times more people die from botulism every year. The likelihood of this happening again was low but we were unrealistically inflating the problem due to the availability heuristic. Our brain is wired to find the optimal balance between speed and accuracy, which means you’ll never be able to completely overcome the availability heuristic. The best way to avoid the availability heuristic, on a small scale, is to combine expertise in behavioral science with dedicated attention and resources to locate the points where it takes hold of individual choices. Nobody likes missing a connection, so you’ll choose airports that give you the best chance of making your connecting flight. If it’s not easy to bring data to mind, then the couple will stick together. when you’re a novice instead of an expert. Some participants were distracted while they reviewed the word lists. In their new book, Richard Thaler and Cass Sunstein provide insight into why investors make certain choices. How do we avoid falling for the availability heuristic? Therefore, it was reasonable to use the availability heuristic for trivial decisions. “Mood and the reliance on the ease of retrieval heuristic.” Journal of Personality and Social Psychology 85(1), Jul 2003, 20-32. You consider a p… The larger point is the final decision was not based on actual frequency data—it was made on data that came to mind most easily.[15]. As expected, producing more arguments made both groups less likely to agree that the number of years of schooling should be reduced. Third, when a cause of death had a 2:1 ratio or more–or, when one cause of death was at least twice as likely as the other–people could identify it as being more frequent. If you’re a happy multitasking novice in a position of leadership, you’re more likely to recall events that are frequent, extreme, negative, recent, and vivid. Each new reason provides a diminishing return, and at a certain point, giving additional reasons will actually be counterproductive. Now suppose I ask you how often you drove in the last month. We’ve seen that a variety of factors make something easier to recall: frequent, extreme, negative, recent, and vivid events come to mind easily, which means they have an outsized influence on your judgments and decisions. For this reason, if we’re trying to judge whether something is likely to happen (to make a risk assessment) if a similar event has occurred recently and/or past instances induced strong emotions that made their occurrence more memorable, we’re much more likely to predict that the event is likely to occ… You’re basing your prediction on the ease with which you can bring to mind just enough data to answer the question: will this couple get a divorce? People cancel their insurance policies if they don’t feel these policies protect them. People experience more positive things than negative things. But when they recalled ten details (not so easy), they believed it happened further in the past. Here are some of Pinker’s data: Pinker’s thesis received a strong reaction. when you’re in a position of leadership or feel powerful, instead of in a submissive role. [10] When it’s easy to think about depression, people are more likely to think more people are depressed. “Bad is stronger than good.” Review of General Psychology, Vol 5(4), Dec 2001, 323-370. 1. 4, 2012. The problem is consumers buy insurance based not on actual risk but on perceived risk. It compromises your judgment. If you’re a non-expert, then you’ll rely on ease-of-recall if you possess just enough knowledge in a domain to retrieve information in your memory about it. If they added up the waste they would see that the slow kettle was a real problem and there was probably a simple solution. Think about how many words start with the letter k compared to the number of words with k as the third letter. Steven Pinker writes in Enlightenment Now that “a quantitative mindset, despite its nerdy aura, is, in fact, the morally enlightened one, because it treats every human life as having equal value rather than privileging the people who are closest to us or most photogenic.”[46]. “Driving fatalities after 9/11: a hidden cost of terrorism.” Applied Economics, 41:14, 1717-1729. This trend continues right up until the present. These shortcuts are called heuristics. People were asked to recall the Oklahoma City bombing. “Finding the face in the crowd: an anger superiority effect.” Journal of Personality and Social Psychology, 54(6), 917-924. [26] Attneave, F. (1953). You’ll think about when you’ve been stuck on the runway in a snowstorm. The median length of a flood insurance policy is between two and four years. I’m not saying that this is a replacement for a retrospective but it can help us avoid this problem and weed out the waste that we don’t think of in our retrospectives. Pete’s Beach, Florida. When they compared the numbers, the researchers found that when people thought of how often they ate out in the recent past, the people who thought of two instances of eating out were more likely to perceive themselves as the kinds of people who eat out compared to the people who thought of ten instances of eating out (5.5 vs. 4.4 on a scale of 1 to 7). (2006). If you find it easy to come up with a story, then you’ll use the ease of creating the story as a shortcut for predicting divorce. [23], What’s even more strange is that it’s simply enough to expect thinking of examples to be difficult. Because words where k is at the beginning, such as kite, keep, or kayak, come to mind easily when you’re thinking of the letter k. They are readily available in your memory. Does the letter k occur more often at the beginning of a word or as the third letter? In Enlightenment Now: The Case for Reason, Science, Humanism, and Progress, Pinker’s follow-up to Better Angels, Pinker writes: “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. Before Bill Clinton left office, he mandated that the standard for arsenic in drinking water be reduced from 50 parts per billion to 10 parts per billion. But as it becomes harder to remember a flood, it will begin to seem floods don’t occur very often after all. Your brain has categorized people and things into different buckets based on various features. Look for contrary examples. [16] Garrick Blalock, Vrinda Kadiyali & Daniel H. Simon (2011). Things that are easier to recall have several attributes in common: Although the availability heuristic works by substituting frequency data for other inputs that come to mind more easily. The same distinction wasn’t true for subordinates: when subordinates recalled two moments of leisure from the previous two weeks, they gave it a happiness rating of 3.85. Consider the controversy in 2001 over how much arsenic should be allowed in drinking water. [46] Pinker, S. (2018). They also strike at random: you can see a shark coming, but it’s impossible to predict when a coconut might fall. Next, let’s extend beyond thought exercises and enter the real world. The availability heuristic also affects whether, where, and how you invest your money. We make a judgment based on what we can remember, rather than complete data. According to a 1999 National Academy of Sciences study, at 50 parts per billion, your risk is 1 in 100. Because of the higher costs, George Bush changed the mandate back to 50 parts per billion. Your mood is a significant predictor of whether ease-of-recall will affect your judgment.
