Here’s my conversation with Matthew Salganik, sociology professor at Princeton University and author of “Bit By Bit: Social Research In The Digital Age.”

We started by talking about how the digital revolution has changed how our behavior is observed, how that gives companies and researchers more accurate portraits of us, and whether we should be wary of all the data being collected without our consent. We also discussed how selling information has become big business, what kind of ethical rules should be in place for that data, and how it can be misused. Matt also revealed a project he did last spring with his students that taught them how to manipulate their Facebook news feeds (and they’re not even Russian!).
