What does your selfie reveal about your personality? According to research by Lin Qiu and colleagues published in Computers in Human Behaviour [P]eople who scored higher in agreeableness (similar to friendliness) were more likely to show positive emotion in their selfies and to hold the camera in a lower position; high-scorers on conscientiousness were less likely to reveal a private location in the background (presumably because of concerns about privacy); people who scored higher in neuroticism (suggestive of emotional instability) were more likely to pull a duck face; and finally, higher scores in openness-to-experience correlated with showing more positive emotion. Levels of extraversion were not correlated with any of the cues, perhaps because so many people attempt to appear outgoing in their selfies. From BPS Research Digest, August 11, 2015.
