Research paper on inferring personality from young people’s e-mail addresses (University of Leipzig)

“Using 599 e-mail addresses of young adults, their self-reported personality scores and the personality judgments […], it was shown that personality impressions based solely on e-mail addresses were consensually shared by observers. Moreover, these impressions contained some degree of validity. This was true for neuroticism, openness, agreeableness, conscientiousness, and narcissism but not for extraversion.”
