Document Summary
Issues over what the extent is to which findings are real and replicable. Male-female math performance difference: meta-analysis investigated gender differences for math performance. See gender differences during high school, college, and adulthood. There is nothing inferred about the cause or whether this is a valid test. Black-white iq distribution: advantages for whites over blacks, distributions for most groups are largely overlapped, says nothing about the validity of the test. Origins of intelligence: nature vs. nurture. E. g. , a child with poor behavior can be explained by genetics and poor parenting. Both nature and nurture contribute to intelligence. Heritability index = 0. 50 (may be as high as 0. 65) If within-group difference has a genetic component, perhaps between-group difference has genetic component too. Between-group differences may be caused by different factors than within- group difference: genetics. High correlation between parent iq and child iq. Iq of identical twins is highly related, more so than fraternal twins.
