A Facebook data scientist, along with two university researchers, turned 689,003 users’ News Feeds positive or negative to see if it would elate or depress them.
The purpose of the study was to find out if emotions were contagious on social networks, which they are.
Facebook is able to conduct such a study because of a line in the site’s Data Use Policy which says users’ information could be used for research.
Facebook data scientist Adam Kramer helped run the study and says the company wanted to use the results to make Facebook better.
“We felt that it was important to investigate the common worry that seeing friends post positive content leads to people feeling negative or left out,” he says.
“At the same time, we were concerned that exposure to friends’ negativity might lead people to avoid visiting Facebook… In hindsight, the research benefits of the paper may not have justified all of this anxiety.”
