What could someone learn about you from your location? What about your Facebook likes? What about just...your face? You’re probably thinking — not much. But Stanford researcher Michal Kosinski says that even superficial data have the potential to expose some of the most intimate details of our lives. Kosinski’s research is provocative, and he has a track record of drawing attention to unexpected risks that come with digital technologies. He argues we live in “a post-privacy” world, and he says the sooner we admit to that reality, the sooner we can start working to improve it.
