Rationality for Mortals

Más información sobre el libro

What is the nature of human wisdom? For many, the ideal image of sapiens is a heavenly one: an omniscient God, a Laplacean demon, a supercomputer, or a fully consistent logical system. Gerd Gigerenzer argues, in contrast, that there are more efficient tools than logic in our minds, which he calls fast and frugal heuristics. These adaptive tools work in a world where the present is only partially known and the future is uncertain. Here, rationality is not logical but ecological, and this volume shows how this insight can help remedy even the widespread problem of statistical innumeracy.RATIONALITY FOR MORTALS (which follows on a previous collection, ADAPTIVE THINKING, also published by OUP) presents Gigerenzer's most recent articles, revised and updated where appropriate, together with a newly written introduction.
