In the middle of multiple rows about privacy, Facebook's Mark Zuckerberg has mentioned privately that he has enough information on users to tell if their relationship is going to end.

According David Kirkpatrick’s soon to be released book, “The Facebook Effect“, Kirkpatrick confirms that relationship patterns were something that Mark Zuckerberg often toyed with. In the book, Kirkpatrick writes that as the service’s engineers built more and more tools that could uncover such insights, Zuckerberg conducted experiments.

For instance, he concluded that by examining friend relationships and communications patterns he could determine with about 33 percent accuracy who a user was going to be in a relationship with a week from now. To deduce this he studied who was looking which profiles, who your friends were friends with, and who was newly single, among other indicators. Indicators included if you were chatting with another girl instead of your girlfriend? Are you being tagged in a lot of photos with the same person?

Since Facebook has a lot of information about who you are viewing regularly as well as what your communication patterns are it is possible to determining the future of your relationship. In otherwords they are actively monitoring your behavior on the site to determine what should be displayed in the feed. Maybe soon we will get notifications that your relationship is on the rocks.
