Forbes writes: Facebook conducted a massive psychological experiment on 689,003 users, manipulating their news feeds to assess the effects on their emotions.

The details of the experiment were published in an article entitled “Experimental Evidence Of Massive-Scale Emotional Contagion Through Social Networks” published in the journalProceedings of the National Academy of Sciences of the United States of America.
