Fast and frugal school researchers emphasize that evolutionary pressures guarantee that we will generally do a good job making “ecologically rational” choices, using inborn capacities to process environmentally available information, even when we make judgments that seem illogical or under-informed. Heuristics can be employed quickly and effortlessly, and that is inherently advantageous; more strikingly, they typically produce answers that are superior to those that would be generated by more effortful or informed agents because readily-processed single cues, or small numbers of cues, more consistently predict a decision-relevant feature of the world than do multiple cues. People generally use simple search rules that tell them what cue to look for first that will discriminate between one judgment or decision and another, stopping rules that tell them to look for no further cues once they have found sufficient discriminating ones, and decision rules that tell them which judgment to make or what course of action to take at that point.

Keywords: fast and frugal heuristics; Gigerenzer; massive modularity; lexical decision making; ecological rationality; heuristic selection; evolutionary psychology; informational encapsulation; adaptive toolbox; over-fitting regressions
