Are We Rational Beings or Not?

| December 7, 2010

How is a rational decision made? Rational models of cognition typically consider the abstract computational problems posed by the environment, assuming that people are capable of optimally solving those problems. A basic challenge for rational models is thus explaining how optimal solutions can be approximated by psychological processes. Psychologists Sanborn, Griffiths, and Navarro outline a general strategy for answering this question, namely to explore the psychological plausibility of approximation algorithms developed in computer science and statistics.
