[1] [2] Intelligence in the normal range is a polygenic trait, meaning that it is influenced by more than one gene, [3] [4] and in the case of intelligence at least 500 genes. [5] Further, explaining the similarity in IQ of closely related persons requires careful study because environmental factors may be correlated with genetic factors.
The Bell Curve: Intelligence and Class Structure in American Life is a 1994 book by the psychologist Richard J. Herrnstein and the political scientist Charles Murray in which the authors argue that human intelligence is substantially influenced by both inherited and environmental factors and that it is a better predictor of many personal outcomes, including financial income, job performance ...
"All psychological traits show significant and substantial genetic influence." "No behavioural traits are 100% heritable." "Heritability is caused by many genes of small effect." "Phenotypic correlations between psychological traits show significant and substantial genetic mediation." "The heritability of intelligence increases throughout ...
Heritability may be estimated by comparing parent and offspring traits (as in Fig. 2). The slope of the line (0.57) approximates the heritability of the trait when offspring values are regressed against the average trait in the parents. If only one parent's value is used then heritability is twice the slope.
For a 2006 study, scientists gave roughly 2,200 adults intelligence tests over a five-year period and results suggested that the bigger the waistline, the lower the cognitive ability.
Similarly, agreeableness is a personality trait that is related to the consideration of others' mental states. [9] The finding that IQ predicts work performance, academic achievement, and health might also point to a link between intelligence and personality, or else be grounds for further research into their relationship.

Hereditarianism is the research program according to which heredity plays a central role in determining human nature and character traits, such as intelligence and personality. Hereditarians believe in the power of genetic influences to explain human behavior and solve human social-political problems.
