The Relative Success of Recognition-Based Inference in Multichoice Decisions

Show Summary Details


The utility of an “ecologically rational” recognition-based decision rule in multichoice decision problems is analyzed, varying the type of judgment required (greater or lesser). The maximum size and range of a counterintuitive advantage associated with recognition-based judgment (the “less-is-more effect”) are identified for a range of cue validity values. Greater ranges of the less-is-more effect occur when participants are asked which is the greatest of m choices (m 〉 2) than when asked which is the least. Less-is-more effects also have greater range for larger values of m. This implies that the classic two-alternative forced-choice task, as studied by Goldstein and Gigerenzer (2002), may not be the most appropriate test case for less-is-more effects.
