Social media profile pics reveal your personality

摘要

What's behind that smile? Analysing the tweets of over 66,000 Twitter users has helped match profile pictures with personality traits. Daniel Preotiuc-Pietro at the University of Pennsylvania in Philadelphia and his colleagues looked at each user's 3200 most recent tweets to categorise their personalities. Meanwhile, 434 members of the group completed a traditional psychological survey. In both cases, users were scored on the "Big Five" personality traits: extraversion, agreeableness, openness, conscientiousness and neuroticism. When the team searched for correlations between test results and the features of profile pictures, a few key relationships emerged.
