During his life, Eysenck's claims about IQ scores and race, first published in 1971, were a significant source of controversy. Eysenck claimed that IQ scores were influenced by genetic differences between racial groups. Eysenck's beliefs on race have been discredited by subsequent research, and are no longer accepted as part of mainstream science.
