The Bell Curve
Jump to navigation Jump to search
The "most provicative claims in the book" are:
- Human “general intelligence” is a scientifically valid concept.
- IQ tests do a pretty good job of measuring it.
- A person’s IQ is highly predictive of his/her success in life.
- Mean IQ differs across populations (blacks < whites < Asians).
- It isn’t known to what degree differences in IQ are genetically determined, but it seems safe to say that genes play a role (and also safe to say that environment does too).
Items 1 and 2, at a minimum, have been pretty well refuted; RationalWiki has a pretty thorough analysis.
