The advantage of models that do not use flexible parameters is that one can precisely show to what degree they predict behavior, and in what situations. In three issues of this journal, the recognition heuristic has been examined carefully from many points of view. We comment here on four...

The recognition heuristic exploits the basic psychological capacity for recognition in order to make inferences about unknown quantities in the world. In this article, we review and clarify issues that emerged from our initial work (Goldstein & Gigerenzer, 1999, 2002), including the distinction...

One-reason decision making is a label for a class of fast and frugal heuristics that base decisions on only one reason. These heuristics do not attempt to optimally fit parameters to a given environment; rather, they have simple structural features and bet that the environment will fit them. By...

This chapter focuses on the recognition heuristic and the less is the more effect. Instead of being unboundedly rational, it is ecologically rational, that is, reasonable with respect to some environments but not others. There are domains in which the recognition heuristic will not work. A wise...
