How do people make decisions when time is limited, information unreliable, and the future uncertain? The authors present the research program on simple heuristics—efficient cognitive processes that ignore information and exploit the structure of the environment. In contrast to the view that less complex processing necessarily reduces accuracy, the analysis of simple heuristics demonstrates that less information and computation can sometimes improve accuracy. This book contains chapters that have been previously published in journals. These chapters present theory, real-world applications, and experimental studies that provide evidence for people's adaptive use of simple heuristics.
