WASHINGTON, D.C. (Worthy News)– Two U.S. universities conducted a psychology experiment with over 600,000 Facebook users unbeknownst to them as Facebook altered their news feeds both positively and negatively to see if it affected their online behavior.
Over 600,000 Facebook users have taken part in a psychological experiment organised by the social media company, without their knowledge.
Facebook altered the tone of the users' news feed to highlight either positive or negative posts from their friends, which were seen on their news feed.

Facebook is facing criticism after it emerged it had conducted a psychology experiment on nearly 700,000 users without their knowledge.
The test saw Facebook "manipulate" news feeds to control which emotional expressions the users were exposed to.
The research was done in collaboration with two US universities to gauge if "exposure to emotions led people to change their own posting behaviours". — Source
