Facebook reportedly manipulated the timeline feeds of nearly 700,000 users in 2012 to study how different emotional expressions change users' behavior. Facebook and its research partners concluded that if a user sees a lot of negative feeds, this user is more likely to post a negative status update. The psychological experiment was carried out without users' consent. UK data regulators are investigating whether Facebook violated data protection laws. Dr. Suzy Moat, Assistant Professor at the University of Warwick Business School joins Julia Sun to discuss the experiment.
