The Lasso Of...Truth?

     What doe s a "lie detector" detect?  Wired took a look at them and the answer is...maybe not a lot.

     I'd like to see a run-off between a polygraph and a good police detective.  People are pretty good lie detectors.  On the other hand, some people are extraordinarily good liars -- and the same coolness and "method acting" that lets such a person lie successfully to others would show nice, truthful responses on the machine.

     It's disappointing.  Who wouldn't like a reliable way to know when someone is lying?  And think of what it would do the political debates....

Sure, and the next thing you are going to tell me is that my Phrenology degree is not worth the paper it's printed on.

I'm reminded of Johnny Carson's rendition of a politician on a polygraph. Every lie got a beep.

There is some research about involuntary brain wave response to images.

"Do you know this person?"

"No"
Beeeeep!
