- Facebook has 1.23 billion monthly users.
- In 2012 they experimented with about 700,000 of their users–without them knowing.
- Facebook intentionally showed these users more negative or more positive posts from their friends.
- The purpose was to see if these posts influenced people’s moods.
- FB didn’t write or change the posts. The experiment lasted 7 days.
- This experiment is generally seen as unethical. Plus, the results were unimpressive.
- Facebook appologized for it. People are still pretty bummed about it.
