Genetic Influence on Personality Traits
Genetics play a significant role in personality, with research suggesting that 40% to 60% of the variance in the Big Five personality traits can be attributed to genetic factors. However, it's emphasized that genetic potential requires environmental stimulation for expression, indicating that genetics alone do not determine behavior. Individuals may possess certain genetic predispositions, yet these traits remain dormant without appropriate environmental contexts to elicit them. This interplay between genetics and the environment is crucial for understanding how personality traits develop and manifest in everyday life.
