Question

Quizplus · Accepted Answer

Heritability estimates are controversial measures because they can easily be misapplied. They provide information on the extent to which individual differences in a trait are due to genetic factors, but they do not provide precise information on how personality traits develop or the extent to which environmental factors can modify genetic influences. The fact that twin pairs share similar environments can actually increase the role of heredity in these estimates, rather than diminishing it.
