Facebook Experiments Had Few Limits - WSJ

From an overview of the Facebook research team that's getting a lot of social scrutiny this week

"A spokesman said Facebook is considering additional changes.

Since its creation in 2007, Facebook's Data Science group has run hundreds of tests. One published study deconstructed how families communicate, another delved into the causes of loneliness. One test looked at how social behaviors spread through networks. In 2010, the group measured how "political mobilization messages" sent to 61 million people caused people in social networks to vote in the 2010 congressional elections.

Many of Facebook's data scientists hold doctoral degrees from major universities in fields including computer science, artificial intelligence and computational biology. Some worked in academic research before joining Facebook."
