Personality of Programmers

A meta-analysis on 19 independent samples (total N = 1695) highlighted that programming aptitude was associated with three personality traits, conscientiousness, openness, and introversion. Moreover, the three traits explained incremental variance components beyond general mental abilities. In contrast to stereotypical beliefs, programming aptitudes were not associated with socially undesirable traits such as disagreeableness or neuroticism.
