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. They stress the value of evolutionary explanations in all areas of the human sciences.
Most prominently in intelligence research, they purport that genetic predisposition determines individual life outcomes more than do either structured environmental influences (i.e. nurture) or developmental noise respectively.
