Neuroticism
Neuroticism is associated with the experience of negative emotions and emotional instability. It is usually anti-correlated with agreeableness and extraversion. Notably, photos of neurotic people are perhaps unsurprisingly anticorrelated with colorfulness. The average color emotion correlations are also negative. In terms of composition, neurotic people display simpler images and do not respect the rule of thirds. This shows that overall, neurotic people display simple, uncolorful images with negative color emotions. Although this is similar for openness, the photos of neurotic people do not display the aesthetic features that characterize openness.
Neurotic people have a strong tendency not to present faces. When a face is present, they have the strongest positive correlation with displaying reading glasses across all traits and, when a face is present, it is significantly larger. Presence of reading glasses have been associated with perceived introversion and a decrease in attractiveness (Terry and Kroger 1976).
In terms of facial emotions, neuroticism displays, as expected, both a lack of positive emotions and, to a lower extent, the presence of negative emotions. Higher correlations than for negative emotions are obtained with features related to the absence of emotions (neutral and expressiveness). Therefore, the lack of emotion expression is what characterizes their profile pictures, which aligns with the strong social norm against a very sad or angry appearance in profile pictures. In general, when examining facial emotion correlation patterns, we highlight two well aligned clusters: openness and neuroticism in one, and conscientiousness, extraversion and agreeableness in the other.
