Intelligence is worth talking about because both the reality of intelligence and perceptions regarding intelligence set limits on the possible and influence policy. For example, if the population of India on average really is below borderline retardation, the country can never amount to anything. If Latino immigrants really are as stupid as white nationalists hope, then they will always inhabit an underclass and, through intermarriage, enstupidate the American population. IQists–those who believe that IQ is a reliable measure of intelligence–insist that intelligence is largely genetic, which it obviously is, and that IQ tests reliably measure it. The latter is doubtful.
