| Briefly stated, the findings are that when presented with an array of data or a sequence of events in which they are instructed to discover an underlying order, subjects show strong tendencies to perceive order and causality in random arrays, to perceive a pattern or correlation which seems a priori intuitively correct even when the actual correlation in the data is counterintuitive, to jump to conclusions about the correct hypothesis, to seek and to use only positive or confirmatory evidence, to construe evidence liberally as confirmatory, to fail to generate or to assess alternative hypotheses, and having thus managed to expose themselves only to confirmatory instances, to be fallaciously confident of the validity of their judgments (Jahoda, 1969; Einhorn and Hogarth, 1978). In the analyzing of past events, these tendencies are exacerbated by failure to appreciate the pitfalls of post hoc analyses. -- A. Benjamin | |
| ... we must be wary of granting too much power to natural selection by viewing all basic capacities of our brain as direct adaptations. I do not doubt that natural selection acted in building our oversized brains -- and I am equally confident that our brains became large as an adaptation for definite roles (probably a complex set of interacting functions). But these assumptions do not lead to the notion, often uncritically embraced by strict Darwinians, that all major capacities of the brain must arise as direct products of natural selection. -- S.J. Gould, "The Mismeasure of Man" | |
