Jody‘s crew found an article that said that Facebook conducted an experiment in which it altered the News Feeds for hundreds of thousands of users. The experiment was outlined in a paper by the Proceedings of the National Academy of Science. There was no link to the paper but after finding their site and searching it for “Facebook” found there were several experiments conducted with Facebook.
In this particular experiment, the News Feeds of over 680,000 English-language Facebook users either had emotionally negative or emotionally positive posts removed from their feeds. The feeds were still available by clicking a friends timeline but not on their own News Feed unless they reloaded it.
Jody Victor suggests if you use Facebook, do so carefully. Don’t expose too much private information to people outside your circles or the public.
