Personality is a complex concept that is shaped by a variety of factors, including biology, environment, and personal experiences. The heritability of personality, also known as the genetic contribution to individual differences in personality, can help explain how and why our personalities have evolved over time. Heritability is a measure used to assess the degree to which individual differences in a trait are due to genetic variation, as opposed to environmental factors. Most studies of heritability of personality have focused on a few personality traits; these include extraversion, agreeableness, openness, neuroticism, and conscientiousness. These traits are known to have a genetic contribution, as evidenced by twin and adoption studies. Twin studies compare the similarity in personality of identical twins, who share nearly 100% of their genetic information, to fraternal twins, who share only 50% of their genes. If personality is found to be more similar among the identical twins than the fraternal twins, the heritability of the trait can be inferred. Similarly, adoption studies compare the similarity in personality between adoptive siblings, who do not share any genes, to biological siblings, who share genes. These studies can only measure the heritability of personality and not the exact percentage of variance in a trait that is due to genetic factors. Nevertheless, they suggest that the heritability of all five of the major personality traits is significant. For example, research has found that genetic factors account for 40-50% of the variance in extraversion and conscientiousness and up to 60% of the variance in neuroticism. The heritability of personality is not fixed, however, and the environment does play an important role in shaping our personalities. Genetic influences can be modified by environmental factors such as family, peers, and culture. The heritability of personality can also vary across time and place. For example, some studies have found that the heritability of personality traits is higher in industrialized cultures than in traditional societies. Ultimately, it is difficult to predict how much of one’s personality is determined by genes and how much is determined by environmental factors. However, it is clear that both have an influence on the development of our personalities, and their interaction is what shapes who we are.
