FBI捜査官が教える「しぐさ」の心理学

It's fascinating to see real-life espionage skills adapted for everyday understanding. I wonder what inspired the author to make these methods accessible to the general public.

I've tried applying some of the techniques, but I’m curious whether these cues work across different cultures and contexts or if they’re more situational.

Certain gestures or postures made me see everyday interactions in a new light. I’d love to hear what others found most eye-opening.
