On the Binary Quality of Recognition and the Inconsequentiality of Further Knowledge: Two Critical Tests of the Recognition Heuristic

摘要

The recognition heuristic is claimed to be distinguished from notions of availability and fluency through its categorical or "binary" treatment of information and the "inconsequentiality" of further knowledge to inferences based on recognition. Using the city-size task of Goldstein and Gigerenzer (2002) we demonstrate that: (1) increasing the validity of other information in the environment decreases the reliance on recognition; (2) cities that are both recognized and have other information known about them (e.g. they have a soccer team) are chosen more often than those which are simply recognized; and (3) there is a negative correlation between the time taken to identify a city and the proportion of times it is selected as the larger of a pair. None of these results is predicted by the process model of the recognition heuristic. The implication of the results for the distinction between the recognition, availability and fluency heuristics is discussed.
