Feelings in Facebook status updates 'contagious,' spread like virus: Study
Positive or negative posts on Facebook can impact the moods and posts of friends on your list, according to a new research.
The research from the University of California, San Diego, published in PLOS ONE, analyzed over a billion anonymised status updates among more than 100 million users of Facebook in the United States.
The study found that positive posts beget positive posts and negative posts beget negative ones, with the positive posts being more influential, or more contagious.
"Our study suggests that people are not just choosing other people like themselves to associate with but actually causing their friends' emotional expressions to change," said lead author James Fowler, professor of political science in the Division of Social Sciences and of medical genetics in the School of Medicine at UC San Diego.
There is abundant scientific literature on how emotion can spread among people - through direct contact, he added.
The researchers analyzed anonymous English-language status updates on Facebook in the top 100 most populous cities in the U.S. over 1,180 days, between January 2009 and March 2012.
