The Availability Heuristic
(reading time – 40 sec.)

After seeing several news reports of car thefts in your neighborhood, you might start to believe that such crimes are more common than they are. This tendency to estimate the probability of something happening based on how many examples readily come to mind is known as the availability heuristic. It is essentially a mental shortcut designed to save us time when we are trying to determine risk.

The problem with relying on this way of thinking is that it often leads to poor estimates and bad decisions. Smokers who have never known someone to die of a smoking-related illness, for example, might underestimate the health risks of smoking.
