Facebook's Emotional Manipulation Study: When Ethical Worlds Collide

The research community is buzzing about the ethics of Facebook’s now-famous experiment in which it manipulated the emotional content of users’ news feeds to see how that would affect users’ activity on the site.

When you use the Facebook Connect [1] login system, another website may ask for permission to “post to Facebook for you.” But what does this message mean? If you click “Okay”, what can the site do to your profile?

Motivated by this confusion, we explored Facebook Connect login permissions with the twin goals of understanding what permissions websites are given when a user logs in with Facebook and whether users understand that they are authorizing those permissions. Here is a working draft of our research report.
