GoKawiilStudy of 1 million people finds 1,200 gene variants tied to Big Five personality traits
Researchers analyzed genetic data from more than a million people and identified roughly 1,200 common genetic variants associated with the Big Five personality traits: extroversion, agreeableness, conscientiousness, neuroticism and openness. Published in Nature and led in part by Michel Nivard at the University of Bristol, the work is the largest genetic analysis of personality to date, though each variant explains only a small share of trait variation.
