Jan 1, 2008 · Plot showing how use of the recognition heuristic can lead to a less-is-more effect. The recognition validity α is 80%, the knowledge validity β is 60%, the total number N of objects is 83, and the number n of objects recognized varies.

Jan 1, 2023 · Recognition-driven inference can give rise to the less-is-more effect (LiME), whereby individuals who recognize many of the items often perform worse than individuals who recognize fewer of the items (Reference McCloy, Beaman and Smith Goldstein & Gigerenzer, 2002).
Jul 4, 2011 · We review research addressing four key aspects of the recognition heuristic: (a) that recognition is often an ecologically valid cue; (b) that people often follow recognition when making inferences; (c) that recognition supersedes further cue knowledge; (d) that its use can produce the less-is-more effect – the phenomenon that lesser states ...
Jan 1, 2023 · A group-level analysis of these data provides evidence in favor of the less-is-more effect: there is strong evidence people make decisions consistent with recognition, and that these decisions are more accurate than those based on knowledge.
Jan 1, 2023 · When recognition memory is imperfect, the less-is-more effect occurs if and only if there exist n e,1 and n e,2 such that n e,1 < n e,2 and Pr (n e,1) > Pr (n e,2). I next propose a simple model of how people make inferences when recognition memory is imperfect.
Substantial recognition validity. The recognition validity for a given criterion must be substantially higher than chance (α >.5). Evaluating the recognition validity requires the existence of reference class R of objects (Goldstein & Gigerenzer, 2002, p. 78; Gigerenzer & Goldstein, 1996b, p. 654).

Jul 4, 2010 · The “less is more effect” (LIME) occurs when a recognition-dependent agent has a greater probability of choosing the better item than a more knowledgeable agent who recognizes more items.
