No, of course not. There are always exceptions to every rule. But we do also have a lot of ways that are a good indication. I wrote this story during the Kavanaugh hearings when people were saying we had no way to know who was telling the truth. Meanwhile, he was a classic example of the Pinocchio effect (a know lying tell) where he didn’t just answer the questions but said way too much. She, on the other hand, was straightforward and to the point even though it was clearly very hard on her.

I’m a fan of Gladwell. I’ll have to look for that book.
