One Million Genomes Reveal How Genes Shape Personality and Health
Key Takeaways
- A genome-wide association study involving more than one million people reveals genetic contributions to personality traits.
- The analysis flags potential causal effects of those genetic contributions on physical and mental health as well as behavior.
- Researchers needed an exceptionally large sample because individual genetic variants have very small effects on complex traits.
- Careful handling of confounders was essential to separating genetic signal from environmental and methodological noise.
