It is a common finding that white Americans as a group score significantly higher on IQ tests than do black Americans. Does this prove that white Americans are more intelligent?…
Consider a simple experiment. Take a group of 200 infants. During their childhood, call half of them low-IQ, tell them no one from their group has even been President of the United States, chronically underfund their schools, and to keep it interesting, give them a daily sprinkling of lead paint chips in their diet. When they reach age 18, give both groups the same IQ test under identical conditions. Would you expect the high-IQ group to actually score higher? Probably so. Would it prove the high-IQ group has an innate genetic superiority? Probably not.
