Facebook's Emotional Experiment on Users

In 2012, Facebook secretly conducted a massive psychological experiment on its users to see if it could alter their emotional state. Unbeknownst to users, Facebook tampered with the news feeds of nearly 700,000 people, showing them an abnormally low number of either positive or negative posts. The experiment aimed to assess whether more positive or negative comments in a Facebook newsfeed would impact how the user updated their own page.
