How to tell when someone lies

Only if they're going to record your face and play it back frame by frame to see if you were lying.

I tend to believe that people can condition themselves to evade this sort of detection. Same for the traditional lie-detector tests.

According to the article, there are muscles in your face that you simply cannot control.

Muscles that you cannot control directly, but you can artificially alter your emotion. For instance, an actor may remember a really sad time to portray sadness; the sadness is real, just not for the reason those that see it will think.

Good point.

Thats not a point at all.
He WAS crying and sobbing the story says.
You can be sad about previous emotions all you want, the fact is you cannot mask the anger and disgust.

Good point.

I don't know. Actors train themselves to get caught up in the moment so to speak. And if you trained yourself to mask the receding emotion of anger persay completely, then the emotion you're trying to pull off will work.

He might have been crying for a reason that was not his wife's disappearance. That is what WW is trying to say.

without reading all of that, when I'm talking with a friend or something and I feel he/she is lying I start asking tons of questions, not directly, but indirectly and keep record in my own head of this, and try to peice together their story best I can until I determine if they are in fact lying, or not.

I'd be pissed if someone killed my pregnant wife. I understand it was in fact he that killed her, but I could understand the emotions of "anger and disgust" being displayed.

At that point, her status was "missing." The only way he'd be angry at her death was if he murdered her.
