Sažetak
Personality heritability is an old issue in personality psychology. Behavioral genetic studies over the past several decades converge on the conclusion that all traits are heritable to the similar degree and that there is a little evidence about differential heritability of personality traits. Recent meta-analysis (Vukasovic & Bratko, 2015) shows that average effect-size for the genetic effect is .40, and that shared environment has negligible contribution to the individual differences in broad dimensions from different personality models. However, this robust behavioural genetic finding is not so sound when one looks closer to the individual studies because: i) the huge majority of behavioral genetic studies comes from the Western, Industrialized and mostly Individualistic cultures ; ii)more than a half behavioral genetics studies are not based on independent samples ; iii) some personality models are neglected in the behavioural genetic literature ; and iv) there is obvious difference between the results of twin and family/adoption studies in personality field. Second issue is heritability of the construct which correlates with a broad personality dimensions. Personality dimensions has broad net of relatively weak but interpretable and theoretically important correlates. These personality correlated constructs are also heritable to the similar degree, and their overlap with personality tend to be due (but not exclusively) to the shared genetic influence. The importance of personality in understanding the heritability of the personality correlated construct will be illustrated with the several examples: prejudice, educational achievement, knowledge and ability, well-being, etc.
