Facebook conducted secret experiment on users’ emotions

Facebook has conducted a secret massive psychology experiment on its users to find out how they respond to positive and negative messages – without telling participants. What Facebook did was to alter the tone of the users’ news feed to highlight either positive or negative posts from their friends, which were seen on their news feed.  Scientists working in the project then monitored the users’ response, to see whether their friends’ attitude had an impact on their own.

“The results show emotional contagion,” wrote a team of Facebook scientists.

Over 600,000 Facebook users have taken part in a psychological experiment conducted by the  the social media company, without their knowledge.

The study was carried out over a week in January 2012 for scientific purposes. But evidence that social media can have such a strong impact on people’s mental state will certainly be of interest to advertisers.

“They then monitored the users’ response, to see whether their friends’ attitude had an impact on their own.

“The results show emotional contagion,” wrote a team of Facebook scientists, in a paper published by the PNAS journal – Proceedings of the National Academy of Scientists of the United States.

“When positive expressions were reduced, people produced fewer positive posts and more negative posts; when negative expressions were reduced, the opposite pattern occurred. These results indicate that emotions expressed by others on Facebook influence our own emotions, constituting experimental evidence for massive-scale contagion via social networks.”

Facebook were able to carry out the experiment because all users have to tick a box agreeing to their terms and conditions. These include “internal operations, including troubleshooting, data analysis, testing, research and service improvement.”

In the study, the authors point out that they stayed within the remit of the agreement by using a machine to pick out positive and negative posts, meaning no user data containing personal information was actually viewed by human researchers.

So, so, the experiment took place in January 2012 amid the Greek economic crisis. No wonder that KTG-ians on Facebook were so angry and mad – because FB was displayed them only my frustrating news about the economic future of Greece?
