Availability Heuristic

The availability heuristic is a mental shortcut that occurs when people make judgments about the probability of events by the ease with which examples come to mind. The availability heuristic operates on the notion that, "if you can think of it, it must be important." The availability of consequences associated with an action is positively related to perceptions of the magnitude of the consequences of that action. In other words, the easier it is to recall the consequences of something, the greater we perceive these consequences to be. Sometimes, this heuristic is beneficial, but the frequencies that events come to mind are usually not accurate reflections of their actual probability in real life. For example, if someone asked you whether your college had more students from Colorado or more from California, under the availability heuristic, you would probably answer the question based on the relative availability of examples of Colorado students and California students. If you recall more students that come from California that you know, you will be more likely to conclude that more students in your college are from California than from Colorado.
