Facebook altered users' News Feeds for its psychology experiment

As indicated by a new paper in the Proceedings of the National Academy of Science, Facebook changing the News Feeds for thousands of its users as a feature of psychology research conducted by the Facebook's on-staff data researcher. By logically modifying News Feeds, the test looked to study the positive and negative impact goes through social networks, at last conclusion states that "in-person interaction and nonverbal cues are not strictly necessary for emotional contagion."

To test and study the hypothesis, the specialists identified 689,003 distinctive English language adopted Facebook users, and started removing negative posts from a group and positive posts from another group. As indicated in the paper, "when a person open their News Feed, posts that has emotional content of the similar emotional valence, every emotional post had between a 10% and 90% chance (based on their User ID) of being removed from their News Feed for that particular review." The posts were still accessible by visiting their friends timeline directly or refreshing the News Feed. The researchers also stated that they are not altering direct messages sent between users.
