You know, the dozens of privacy policy updates you've probably received in the past few weeks. I'm talking about updates from email providers, social media companies, banks and what seems like every random internet service you've ever interacted with -- all letting you know how they're collecting and using your data.

But here's the thing: When you click "accept" on a privacy policy, even if you've read it from start to finish, you're most likely still in the dark about what you're consenting to. That's because privacy policies don't really tell you about all the things that can be done with your data. With statistical analysis and, more recently, artificial intelligence, companies that have your data can draw all kinds of inferences about you. And they use that in ways you might never predict.
