![]() ![]() “Subjective Probability: A Judgment of Representativeness.” Cognitive Psychology 3 (1972): 430–54.Ī classic example of this cognitive bias in action, is the recruitment process of the majority of organizations around the globe. The representative heuristic is a cognitive bias the leads us to make judgments based on comparisons to something else in mind. In short, the availability heuristic leads to bad decision-making because misleading information tends to come to mind more easily than accurate ones. Judgment under uncertainty: Heuristics and biases. Divorces will appear probable if divorces are prevalent among the instances that are retrieved in this manner.” 2 Tversky, A., & Kahneman, D. “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. The availability heuristic also explains why certain catastrophic events occur, like divorce. The availability heuristic refers to our tendency to make judgments based on information that can be easily recalled from memory.įor example, let’s say you’re driving on a highway at 70 mph like everyone else, but then you see a catastrophic accident and the other motorists slow down to 50 mph.īecause the possibility of an accident is more ‘available’ in your mind, you’re more likely to slow down to 50 mph as well, even though the probability of an accident occurring remains unchanged. Just like the subjects in this experiment, we tend to fall prey to anchoring on a daily basis.įor example, you’re more likely to buy a “special deal” sandwich for $5, if you previously saw another sandwich that cost $20.Įven though the price of the more expensive sandwich is irrelevant to your buying decision, the cognitive bias of anchoring will lead you to perceive the lower priced sandwich as a cheap bargain, when it may not be. In other words, the subjects were ‘anchored’ by the wheel of fortune numbers, which swayed their final estimations. ![]() The average estimates of the participants who saw 65 on the wheel of fortune was 45%, whereas those who saw 10 had a lower average estimate of 25%. Kahneman and Tversky then asked the subjects two questions: Is the percentage of African nations among UN members larger or smaller than the number you just wrote? What is your best guess of the percentage of African nations in The catch however, was that the wheel of fortune had been rigged to stop only at numbers 10 or 65, rather than a range of numbers between 0 to 100. The Undoing Project: A Friendship That Changed Our Minds. In a classic experiment, Kahneman and Tversky recruited students from the University of Oregon as subjects, spun a wheel of fortune and asked them to write down the number on which the wheel stopped. ![]() 5 Cognitive Biases That Affect Your Decision-MakingĪnchoring refers to the idea that we are easily swayed by irrelevant information presented to us prior to making a decision.
