The Impact of the Availability Heuristic on Decision-Making and Risk Perception

The present essay will consider the availability heuristic, a cognitive bias whereby individuals’ judgment regarding the likelihood of certain events is altered by the ease with which they are able to formulate examples. Historical developments from early psychological studies through its formalization by Kahneman and Tversky will underline its main features, underlie its operations, and discuss its influence on decision-making, risk perception, and errors in judgment. Case studies tend to reveal the heuristic’s insistent influence in everyday life, notably in crime perception, estimation of health risk, and investing in the financial markets.
