, former CIA officers teach you how to detect deception. The techniques are fairly straightforward, but difficult to apply. This is because you must become a good listener, not just with your ears but also your eyes. I think it's hard not to focus on what you're saying, whereas the key is to focus on what the other person is saying (including with their body language).
The authors provide a lot of anecdotes as examples to help the reader decipher deception, which I appreciated. But little scientific data is shared. The authors profess that these techniques worked for them, but we have no way of knowing how accurate their assessments were, nor how many false positives they generated. Nevertheless, if you're in a profession where detecting deception is important (e.g. law enforcement), this is probably a must-read book.
