Availability Heuristic – How it affects our judgments?Home/Strategy/Availability Heuristic – How it affects our judgments?
Idea in shortWhen trying to make a decision, a number of related events or situations might immediately spring to the forefront of your thoughts. As a result, you might judge that those events as more frequent or probable than others. You give greater credence to this information and tend to overestimate the likelihood of similar things happening in the future. Availability heuristic operates under the principle that: if you can think of it, it must be importantWe tend to believe things that come more easily to mind as more accurate reflections of the real world. In general, a heuristic is a rule-of-thumb – a mental shortcut that helps guide our decisions. Our brains use mental shortcuts (heuristics) to make split-second decisions. Heuristics, also termed biases, affect how we process complex information. The availability bias happens when we judge the likelihood of an event. Origin of Availability HeuristicIn the late 1960s and early 1970s, Amos Tversky and Daniel Kahneman started working on examining human judgment under uncertainty. Prior to that, the predominantly held view of human judgment was of humans as rational actors. Kahneman and Tversky discovered that judgment under uncertainty relies on a limited number of simplifying mechanisms rather than extensive cognitive processing. One simplifying mechanism we employ to judge an event is based on how many similar instances come to our mind. In 1973, Amos Tversky and Daniel Kahneman labeled this phenomenon availability heuristic. What is Availability Bias?An availability heuristic is a mental shortcut that relies on immediate examples that come our mind when evaluating a specific topic, concept, method or decision. We tend to use a readily available facts to base our beliefs about a comparably distant concept. We tend to assume that future events will closely resemble our recent experience. The frequency of an event’s occurrence and the ease of recall affect our judgment. We tend to attribute higher weightage to information that most easily comes to our minds. Because of the availability bias, our perceptions of risk may be in error and we might worry about the wrong risks. This can have disastrous impacts. Ease of recall suggests that if something is more easily recalled in memory it must occur with a higher probability. This phenomenon distorts our understanding of real risks. For example:
Decision-making agencies, from families to governments spend inordinate time to address unfounded fears. In so doing, they ignore much more common and controllable threats. In this process, they also misdirect resources that are put to better use elsewhere. DemagogueryDemagogues have understood the coercive effect of our availability biases. They rouse rabble to fever pitch and ensure that our mental alertness is always on the high. Historically, demagogues have leveraged our availability bias and tap into our fears to shape public perceptions and manipulate the populace. For example, Joseph Goebbels, the Nazi propaganda minister mastered this manipulation technique to move the entire German population and the country to World War II:
On plane crashesPerhaps you had just read a news article about a massive plane crash. The fear-invoking headline, paired with the image of a wrecked plane wreathed in flames, leaves an easily recalled impression. This leads you to wildly overrate your chances of dying in a similar plane crash. This is the availability heuristic bias at work. Hence, you tend to rate air travel as more dangerous. The mode of transportation that Americans chose in the aftermath of September 11 attacks profoundly demonstrate this heuristic. The availability bias instilled fear of air travel among large segments of the American population. In contrast:
Behavioural economicsIn Thinking Fast and Slow[1], Daniel Kahneman writes:
This heuristic also manifests itself in business, stock markets, economics, weather, etc. Our short-term analyses aren’t only invalid, but also unhelpful and misleading. For example, a legion of economists pronounced events like the 2009 financial crisis as unthinkable right until it happened. The booming economy and the US housing bubble that preceded the 2007-2008 financial crisis provided positive indicators for an upward economic trajectory. These indicators proferred no justification to assume the worst-case scenario of a global economic crisis, which eventually happened. In this case, the economists fell prey to the availability heuristic. On a smaller scale, a study[2] by Karlsson, Loewenstein, and Ariely (2008) showed that people are more likely to purchase insurance to protect themselves after a natural disaster they have just experienced than they are to purchase insurance on this type of disaster before it happens. In support of this study, Max Bazerman adds[3]:
PrevalenceThe longer we preoccupy ourselves with an event, the more available it will be in our minds. And, the more probable will we believe the event to occur. The problem is that certain events tend to stand out in our minds more than others. Excessive media coverage can also cause this to happen. Sometimes, the novelty or drama surrounding an event can cause it to become more available in our minds. Because the event is so unusual, it takes on greater significance, which leads us to incorrectly assume that the event is much more common than it really is.
Heuristics play an important role in how we make decisions and act upon information in the world around us. The availability heuristic can be a helpful tool, but it is also important to remember that it can sometimes lead to incorrect assessments. Just because something looms large in our memories does not necessarily mean that it is more common. Hence, it can be helpful to rely on numerous tools, reliable data and decision-making strategies when we making decisions and choices. SummaryThe availability heuristic describes behavior that results from numerous shortcuts that our brain makes in order to process all of the world’s information. The availability heuristic is a core cognitive function that saves mental effort we often go through. Unfortunately, simply knowing how it works is not sufficient to completely overcome it. Although awareness alone cannot change human behavior, it is essential to support and implement policies that take our heuristics into account. Taking steps to recognize and check the availability heuristic is crucial for designing fair systems, equitable treatment for consumers and citizens, architecting regulations, writing laws, preventing crimes, improving accountability, etc. APAMLAHarvardVancouverChicagoIEEE Think Insights (September 16, 2022) Availability Heuristic – How it affects our judgments?.
