The Noisy System of Guilt
Lie detection—and more specifically, the polygraph machine—has only proven to blur the line between innocence in guilt.

Or does it only create a breach of privacy? John-Dylan Haynes and Frank Tong discuss how advances in brain scanning could play into this grey area of grey matter.
