In Many Societies, the Average IQ Scores of Minority Groups

question 235

Multiple Choice

In many societies, the average IQ scores of minority groups are lower than the average IQ scores of the dominant or majority groups. Why can't heritability estimates be used to explain group differences in intelligence?

• A) Heritability estimates can only be used to predict individual variation from standardized test scores and do not apply to group differences.
• B) Estimates of genetic differences apply only to characteristics that are determined by a single gene or gene pair.
• C) Unless the environmental conditions of two racial groups are virtually identical, it is impossible to estimate the overall genetic differences between the two groups.
• D) Heritability estimates only apply to intelligence scores that are averaged over a period of at least 20 years, and group data does not exist for that period.
