And what they did was they put people in brain scanners to look at what areas of their brain were activated.
And half of the people, they asked them personal questions.
So they asked them to reveal.
The other half were asked different questions that didn't give them the opportunity to reveal.
And what they found was that the people who got to reveal, the pleasure centers of their brain were activated.
If they told the truth.
Well, they didn't even tell, like the questions were not necessarily places where you would lie.
They were like, what's your favorite ice cream flavor?
Like they were just anything about yourself, not particularly sensitive, but talking about yourself, revealing about yourself.
The pleasure centers of the brain activated.
Yeah.
relative to when you weren't talking about yourself.
And that to me was like, wow, this is like, these are the really old brain structures.

Yeah.

So the third study that rocked me, I encountered this oldie but goodie or baddie study, depending on how you view the conclusions, about what they did in this study was they videotaped preschoolers as they were watching a kind of scary movie.
And so they were videotaping them to see how much they expressed on their faces, how much seeped out, how much did they show on their faces of their feelings.
