Study Uncovers Genes Behind Personalities
The study focused on the relationship between genes and the Big Five personality traits, analyzing genetic data from over a million individuals. The results revealed that approximately 7.4% to 10.6% of the variations in personality traits can be explained by genetic factors, with 1,260 genetic variants identified as being associated with these traits, including 824 that were not previously linked to genetics. However, the DNA's ability to predict personality on an individual level does not exceed 4%, as environmental factors, diet, and culture significantly influence personality development. The study also found genetic links between certain traits, such as extraversion, and the risk of contracting COVID-19. Nonetheless, genes do not encompass the full picture of human personality, which is primarily shaped by external factors.
