Over all, his research argues that when it comes to privacy, policy makers should carefully consider how people actually behave. We don’t always act in our own best interest, his research suggests.

Mr. Acquisti offers a sobering counterpoint. In 2011, he took snapshots with a webcam of nearly 100 students on campus. Within minutes, he had identified about one-third of them using facial recognition software. In addition, for about a fourth of the subjects whom he could identify, he found out enough about them on Facebook to guess at least a portion of their Social Security numbers.
I think the Social Security point is less likely to happen to people born recently (as the way that SSN numbers are assigned as been randomized), but man is that creepy.
