Your profile picture in Twitter may tell a lot about your personality, and not just the way you look suggest researchers from University of Pennsylvania in the US.
They used character assessment software to analyze the profile pictures of 66,000 Twitter users, and asked a further 434 people to fill in a psychological survey.
‘Neurotic people have trouble holding back their negative emotions and are likely to set their profile picture as something other than their face, such as a pet or building.’
They sorted the respondents into five personality categories - neuroticism, agreeableness, conscientiousness, extroversion and openness to experience.
According to researchers, users who are agreeable are the most likely to be cheerful, get along with others and smile.
Neurotic people have trouble holding back their negative emotions and are likely to set their profile picture as something other than their face, such as a pet or building, they said.
The profile pictures of agreeable people are one of the most likely to be colorful, and will feature the person laughing, playing with others or smiling broadly.
Conscientious people are those who enjoy "orderliness, planned behavior and self-discipline."
They are more likely to appear older than their years in profile pictures, and will use techniques such as wearing glasses or smarter clothes to achieve this.
Like agreeable people, even extroverts are likely to have colorful profile pictures and are always smiling. They also tend to pose with young people, or adopt other techniques to make themselves appear younger than they are, researchers said.
People who are open to experience are those who enjoy tackling new, exciting experiences and are not afraid to pose in an odd way.
