“As Richard Nisbett and Lee Ross (1980) point out, rationally defensible deductive logic involves a specification from the universal to the particular (“All men are mortal, therefore Robyn Dawes is mortal.”), but much less reliable inductive logic involves generalization from the particular to the universal (“This one Jewish merchant is dishonest, therefore all Jewish merchants are dishonest.”). However, we are prone to do the exact opposite: we under-deduce and over-induce.” PsychologyDecision MakingRationalityCognitive BiasesDeductive ReasoningInductive Reasoning Book:Rational Choice in an Uncertain World: The Psychology of Judgement and Decision Making Source: Rational Choice in an Uncertain World: The Psychology of Judgement and Decision Making
