Representative heuristic: heuristic that involves judging the probability of an event by its superficial similarity to a prototype. Base rate: how common a characteristic or behaviour is in the general population. Availability heuristic: heuristic that involves estimating the likelihood of an occurrence based on the ease with which it comes to our minds.
