In two studies on mobile phone purchase decisions, we investigated consumers' decision strategies with a newly developed process tracing tool called \textit{InterActive Process Tracing} (IAPT). This tool is a combination of several process tracing techniques (Active Information Search, Mouselab,...

In a series of three experiments, participants made inferences about which one of a pair of two objects scored higher on a criterion. The first experiment was designed to contrast the prediction of Probabilistic Mental Model theory (Gigerenzer, Hoffrage, & Kleinbolting, 1991) concerning sampling...

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...
