Decision-Making Strategies Single-feature model Additive model Elimination by aspects model Availability heuristic—readily available Representativeness heuristic—prototype • In another study, subjects were asked, “If a random word is taken from an English text, is it more likely that the word starts with a K, or that K is the third letter?” Most English-speaking people could immediately think of many words that begin with the letter "K" (kangaroo, kitchen, kale), but it would take a more concentrated effort to think of any words where "K" is the third letter (acknowledge). Results indicated that participants overestimated the number of words that began with the letter “K”, but underestimated the number of words that had “K” as the third letter. Researchers concluded that people answer questions like these by comparing the availability of the two categories and assessing how easily they can recall these instances. In other words, it is easier to think of words that begin with "K", than words with "K" as the third letter. Thus, people judge words beginning with a "K" to be a more common occurrence. In reality, however, a typical text contains twice as many words that have "K" as the third letter than "K" as the first letter. Additionally, there are three times as many words that have the letter "K" in the third position, as have it in the first position.[1] • Tversky, A; Kahneman (1973).
