Yahoo! Labs Small World Experiment

TheYahoo! Labs Small World Experimentis designed to test the hypothesis that anyone in the world can get a message to anyone else in just "six degrees of separation". In order to carry out this Experiment, we will collect personal information from ‘Targets’ and ‘Senders’ to make connections between them.

If you agree to participate in the Experiment, you agree to provide Yahoo! Labs and our partners (including Facebook) with certain personal information in order to understand these connections.

You may terminate participation in the Project by deleting the Small World application from your Facebook privacy settings AND by clicking the “Discontinue from Experiment” link in the footer on the Yahoo! Research Small World Experiment website, or by contacting Sharad Goel (smallworld-experiment@yahoo-inc.com). Deletion of the Experiment App alone will not delete your participation and our chain of events will still contain your profile and any other information viewable by others (based on your Facebook privacy settings).

You do not need to be signed-in to the Yahoo! network to access this project, however you must be signed in to Facebook.
