For example, when participants were asked if there are more words in the English language that either start with "k" or have "k" as the third letter, most chose the first option (even though this is incorrect). Participants presumably did so because they could generate more exemplars of words starting with "k" than they could of words with "k" as the third letter in the word. (This particular experiment also ties to the availability heuristic, by which we guess probability by the ease with which an example comes to mind.)[8]
