What is Reddit's opinion of Spy the Lie: Former CIA Officers Teach You How to Detect Deception?

From 3.5 billion Reddit comments

> Did you actually go through the whole training program? Do you think that it's worth it?

I believe the training has changed over the years, but what I did was apparently called eMETT 3.0 Expert Level (I had to go and find my cert to remember). It's hard to say how useful it was for self-defense, but it was definitely very interesting. I find myself catching emotions like disgust and contempt which I'm sure I never would have before that training.

> I'm surprised that you're unsure about the validity of the research.

Not all of it. And it's just that it's more of an art than a science. Someone crosses their arms: it might be because they want a barrier between you and them, or they might just be cold. They might be cold because they are scared (blood pools away from extremities), or they might just have low body fat. Some aspects (not all) of reading body language just aren't for sure.

By the way, somewhat related to this, absolutely check out the book Spy the Lie. It's not about body language at all, but more about the words people choose. Combined with body language you can get a much more complete picture of what people are thinking. I've started to pay much more attention to words since reading that. Things like, an advertisement says "Made with real chicken!" So..."with" real chicken, but not necessarily real chicken exclusively. Got it. "Packaged in America!", so almost certainly not built in America or you'd have said that. It's interesting the words people will use to try and hide the truth without technically lying. The book will absolutely change the way you watch an interview with a politician.
