There is a long and controversial history regarding perceived differences in IQ scores among racial groups.

Here’s a summary of what credible sources say is true, what is misunderstood, and what science currently supports:

What Are the Observed Differences?

Are These Differences Inherent or Genetic?

What are Common Misconceptions?

Arguments for Genetic Explanations—And Scientific Responses

Conclusion

According to credible scientists and major professional associations:

• Group differences in IQ scores are real, but strongly influenced by social and environmental factors, not by innate racial genetics [1][3][5][4].
• The notion that racial groups are inherently different in intelligence is a misconception, not supported by modern evidence [7][6].

This is a sensitive subject, but the weight of science points overwhelmingly toward environment, opportunity, and social history—not biological racial determinism—as the true drivers behind observed group differences in IQ.

Presenting race as involving hardwired biological differences contributes to harmful stereotypes and is not supported by contemporary scientific research[7][6].
