What Your Genes Can, and Cannot, Tell Us About Your Personality
Researchers identified more than 1,260 common genetic variants tied to the Big Five, but said genetics explains only 5% to 10% of personality differences.
- On September 2, researchers published a study in Nature identifying 1,260 genetic variants linked to the Big Five personality traits, offering new insights into biological factors contributing to human behavior.
- Psychologist Elliot Tucker-Drob and colleagues combined 46 study cohorts involving more than 1.1 million people to overcome previous difficulties in untangling personality's genetic component using large population databases.
- The analysis identified 1,260 genetic variants, including 824 previously unknown, explaining roughly 4.8% to 13.3% of personality variation and correlating with health, psychiatric disorders, and life outcomes.
- Princeton University sociologist Dalton Conley noted the findings challenge theories linking neuroticism to serotonin, while epidemiologist Michel Nivard stressed the data provides population-level insights rather than individual personality predictions.
- Researchers stress that personality emerges from a mixture of genetics and environment, with genetic variants representing only a small proportion of overall personality variation despite their measurable associations.

More than a million genomes helped identify DNA variants linked to extroversion, kindness, neuroticism, and other traits. Researchers measured how these traits influenced people’s way of life.
Massive study reveals how much personality comes from DNA
Are you naturally outgoing, anxious, disciplined, or the kind of person who hears “let’s go out” and immediately starts inventing excuses? Science has an explanation. Your personality may be partly written into your DNA, but your genes aren’t running the entire show. A massive new study involving genetic and personality data from more than 1 million people has identified over 1,000 genetic variants associated with major personality traits. The r…
Part of Your Personality Is Encoded in Your Genes. Huge Analysis Links Characteristics to More Than 1,200 Common Genetic Variants
A new meta-analysis pooled data from more than one million people to look at the crossover between DNA and the "Big Five" personality traits: openness to experience, conscientiousness, extroversion, agreeableness and neuroticism
A person's character is shaped by both heredity and life experiences. A recent study involving data from more than a million people revealed over a thousand gene variants linked to personality traits, yet they explain only a small portion of the differences between people.
