Liars typically do this...

Look for secret disgust if you ask

someone a preference-based question. So

disgust is a very negative emotion. We

make it when we don't like something. So

it's when we crinkle our nose up and

flash the upper whites of our teeth. We

do it to inhibit our nasal passages,

like when we smell something bad or

taste something bad. But interestingly,

we also do this when we don't like

something we hear or see. I I see this a

lot with lie detection. So, we do a lot

of lie detection research and I've

noticed lying makes people feel dirty.

We do not like to lie. And so, people

will often lie as they'll make the

disgust expression as they're lying. So,

I'll say, you know, so what do you think

of the new guy? Oh, yeah. Yeah. You

know, he's pretty good. And they hold

this expression up. If they are lying,

they will often show disgust cuz they're

literally discuss it with themselves.
