Anger at Facebook's Mood Manipulation Not Likely to Last
Posted in: Uncategorized
A Facebook researcher apologized after conducting an experiment that temporarily influenced what almost 700,000 readers saw on their news feeds, reviving some customers’ concerns about privacy issues.
The number of positive and negative comments that users saw on their feeds of articles and photos was altered in January 2012, according to a study published June 17 in the Proceedings of the National Academy of Sciences. People shown fewer positive words were found to write more negative posts, while the reverse happened with those exposed to fewer negative terms, according to the trial of random Facebook users.
Adam Kramer, a Facebook data scientist who was among study’s authors, wrote on his Facebook page yesterday that the team was “very sorry for the way the paper described the research and any anxiety it caused.”
