The embryo hunts in secret
According to a paper just published (but available online since 2010), we haven’t found any genes for personality.
The study was a big meta-analysis of a total of 20,000 people of European descent. In a nutshell, they found no single nucleotide polymorphisms (SNPs) associated with any of the “Big 5″ personality traits of Neuroticism, Extraversion, Openness to Experience, Agreeableness and Conscientiousness. There were a couple of very tenuous hits, but they didn’t replicate.
Obviously, this is bad news for people interested in the genetics of personality.
