When it comes to feet and hands, it's a good idea to take the cognitive
over low perspective. So, what you tend to see is a lot of freezing
behaviors when people lie with the freezing hands, with hands and feet.
And, the reason why is because while we're lying, you know, it's
cognitively demanding and it shuts down and it shuts down our other
behaviors. So, one of the things you'll tend to see is people will be a
lot more still because their trying to focus their attention towards the
lie. Alright.

The reason why it's difficult to figure out whether or not someone's lying
or not is because the two emotional perspectives change the behavior.
Alright. So because of cognitive overload, people tend to stop their
movements. Alright. But also because of emotion, people tend to do other
things with their movements. Because there's two theoretical perspectives
underlining lie detection and there's, kind of, different non verbal's for
each, you have to figure out which perspective is working in order to
accurately ascertain what the behavior is.

That's why it's really difficult to, kind of like, say, that like, if
somebody's hands stop, it means something or if somebody's hands move, it
means something. It's all based on their behavior.

Everybody's got something. I mean, I'm a firm believer that if I watch
somebody for long enough, I could figure out what their thing is. But,
that's after watching them for a long time. That's not after just walking
in and being like, lier. That's the wrong way to approach lie detection.

Really, you can't. It's really hard. It's hard. It's hard to determine
whether someone's lying or not. That's why, like you know, it's funny. A
lot of academics publish research. And at the end of the research study it
says, you know, despite what we know, blah, blah, blah, blah, blah, it's
very difficult to determine when someone's lying or not. I don't think
I'll ever get accuracy rates of, you know, 80 or 90 percent or whatever.
