Facebook messed with users' emotions--for science!

Facebook has gotten plenty of flack for its privacy practices, but here’s a new way to distrust the social media service: It may be playing with your emotions.
As reported by The A.V. Club, in January 2012, Facebook adjusted its newsfeed algorithm for several hundred thousand users to see how what you see in your newsfeed affects your emotional state as part of a scientific study.
The resulting paper, published to The Proceedings of the National Academy of Sciences (PNAS), found that people mirror the positive or negative emotions that their friends express in Facebook posts—all without the aid of nonverbal cues like body language or tone of voice.
