To what extent is intelligence inherited?

The degree to which heredity (genetics) contributes to a trait In this case, intelligence Extent to which genes can explain the variation for a trait within a population Heritability coefficient between 0 and 1 Heritability

What evidence could support the idea that intelligence is genetic What evidence could support the idea that intelligence is genetic? What evidence could support the idea that intelligence is learned/environmental?

Intelligence correlations between biological parents and children increases with age. Malnutrition, impoverished environmental conditions, etc. can depress cognitive development Enriched environments do not increase cognitive abilities Baby Einstein and Mozart do not improve intellectual development in children Carol Dweck: efforts should be taken to increase intelligence Fun Facts
