Leaning to expose the liar.

- Did you take my computer yesterday? - No, I didn't. And now let's ask the same question again, while leaning toward the opponent. And if you're sitting, it's more effective to stand up and ask the question while leaning over the interlocutor. Why does it work? Because it's psychological pressure and breaking social boundaries. This is how the brain under pressure begins to produce truth. So I advise you to try this method, you can start with children if you feel they are lying.
