Racial and ethnic group differences in the heritability of intelligence: A systematic review and meta-analysis

摘要: Abstract Via meta-analysis, we examined whether the heritability of intelligence varies across racial or ethnic groups. Specifically, tested a hypothesis predicting an interaction whereby those and groups living in relatively disadvantaged environments display lower higher environmentality. The reasoning behind this prediction is that people (or people) raised poor may not be able to realize their full genetic potentials. Our sample (k = 16) comprised 84,897 Whites, 37,160 Blacks, 17,678 Hispanics residing United States. We found White, Black, Hispanic heritabilities were consistently moderate high, these did differ At least States, Race/Ethnicity × Heritability interactions likely do exist.
