In it, Facebook researchers directly manipulated Facebook users’ news feeds to display differing amounts of positive and negative posts from the people they followed in order to determine whether their subsequent posts were affected by the positivity or negativity of the set of posts they were viewing. This effect, that more positive or negative posts read by a user could change their own emotional state positively or negatively, is the ‘emotional contagion’ referenced in the article.
