A simple, boring, private profile picture could mean you're oversensitive
Psychology has divided the human personality into five core dimensions (known as the Big 5), and through these, they are able to identify certain behavioral patterns. Your social media profile picture may indicate which of these categories you fall under. The Big 5 are openness, conscientiousness, extraversion, agreeableness, and neuroticism, and each one contains characteristics that can be revealed even in a profile picture, according to a study done at the University of Pennsylvania. Researchers there looked at over 60,000 profile images and analyzed specific details ranging from color to facial presentation using state-of-the-art text prediction methods. They found that oversensitive people tend to use profile pictures that are simple and lacking in color, with either blank facial expressions or concealing their faces using objects like sunglasses, even hiding their faces entirely. In contrast, extroverted individuals choose bright, colorful images, often with multiple people included as well and avoiding sunglasses.
