Summary
Despite the high heritability values for intelligence, there are people who still make a variety of arguments to nullify or deny the genetic influence of intelligence. These people use mental gymnastics to argue that even though heritability can be high, environment still matters far more than genetics in determining someone’s intelligence. While no scientist argues that environment is irrelevant, the evidence has mounted that genes are a far more important influence on intelligence than many psychologists believed in the twentieth century.
