The (faulty) “reasoning” of The Bell Curve Differences in a phenotypic score among “populations”* * Note faulty assumption
The (faulty) “reasoning” of The Bell Curve Heritability of IQ score has been calculated in twin studies - if “genetic component” is removed from each “population,” the remaining variation (within “populations”) is due to environmental diffs.
The (faulty) “reasoning” of The Bell Curve Murray and Herrnstein conclude that differences between “populations” must be due to genetic differences since quality of environments can’t be this big. * * This is an example of “argument from incredulity,” rather than from evidence.
The “proper”* experiment * but not ethical or even worthwhile
