Herrnstein and Murray argue that ethnic differences in average IQ scores are substantial and partly genetic in origin. They contend that genetics plays a role in determining intelligence and that some ethnic groups may have genetic advantages or disadvantages when it comes to cognitive abilities. They do not focus on nutritional levels or bias in IQ tests as the primary factors contributing to ethnic IQ differences. While they may acknowledge that environmental factors can play a role, they argue that genetic differences are an important factor to consider.
