Study: Vacation Photos Leading Cause of Facebook Envy
The researchers said that vacation photos were the No. 1 cause of resentment, accounting for more than half of all envy incidents. 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.
Do photos like these make you sad, depressed, or angry?
"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 (PDF).
The sample size is rather small -- just 600 subjects -- but the results are interesting nonetheless. For many, Facebook has become a part of daily life, a means to keep in contact with friends and family scattered across the globe and see what they're up to on a daily basis. Yet those who contribute the least, the lurkers, if you will, end up feeling the worst.
