Facebook has been criticized for making people envious and unhappy due to the constant exposure to positive yet unrepresentative highlights of their peers. Such highlights include, but are not limited to, wall posts, videos, and photos that depict or reference such positive or otherwise outstanding activities, experiences, and facts. This effect is caused mainly by the fact that most users of Facebook usually only display the positive aspects of their lives while excluding the negative, though it is also strongly connected to inequality and the disparities between social groups as Facebook is open to users from all classes of society. Sites such as AddictionInfo.org state that this kind of envy has profound effects on other aspects of life and can lead to severe depression, self-loathing, rage and hatred, resentment, feelings of inferiority and insecurity, pessimism, suicidal tendencies and desires, social isolation, and other issues that can prove very serious. This condition has often been called "Facebook Envy" or "Facebook Depression" by the media.
A joint study conducted by two German universities demonstrated Facebook envy and found that as many as one out of three people actually feel worse and less satisfied with their lives after visiting the site. Vacation photos were found to be the most common source of feelings of resentment and jealousy. After that, social interaction was the second biggest cause of envy, as Facebook users compare the number of birthday greetings, likes, and comments to those of their friends. Visitors who contributed the least tended to feel the worst. "According to our findings, passive following triggers invidious emotions, with users mainly envying happiness of others, the way others spend their vacations; and socialize," the study states.
A 2013 study by researchers at the University of Michigan found that the more people used Facebook, the worse they felt afterwards.
