Profile pictures on social networks are usersu0027 opportunity to present themselves and to affect how others judge them. In most social networks, profile pictures are public by default. 1,122 Facebook users completed a matrices intelligence test and shared their current Facebook profile picture. Strangers also rated the images for perceived intelligence. We use automatically extracted features from profile pictures to predict both measured and perceived intelligence. Intelligence estimation from images is a difficult task even for humans, but experimental results show that human accuracy can be equalled using computing methods. We report the image features that predict both measured and perceived intelligence, and highlight misleading features such as smiling and wearing glasses that are correlated with perceived but not measured intelligence. Our results give insights into inaccurate stereotyping from profile pictures and also have implications for privacy.
