We evolved to be effective deceivers, so if there was a systemic and obvious physical tell (looking left = liar) then evolution would try to eliminate it.

Also self deception helps.

I often think about that. If I can thoroughly convince myself to believe a factual lie, would classic lie detector devices still work on me?

There was an interesting book on the theme that we've evolved to deceive ourselves especially on moral stuff like my side is good, the others are the bad guys https://www.amazon.com/Moral-Animal-Science-Evolutionary-Psy...

Do classic lie detectors work on anyone or is it mostly pseudoscience and theatre?
