Lying Makes The Brain Work Harder
Ant writes "This Wired News article says it seems to take more brain effort to tell a lie than to tell the truth according to functional magnetic resonance imaging (fMRI) scans. Lying caused activity in the frontal part of the brain -- the medial inferior and pre-central areas, as well as the hippocampus and middle temporal regions and the limbic areas. Some of these are involved in emotional responses. During a truthful response, the fMRI showed activation of parts of the brain's frontal lobe, temporal lobe and cingulate gyrus."
Lies require thought and planning.
The truth requires citing specific knowledge.

That's a helluva strong magnet!!!!!!!

You are right. Intelligent liars create backstories too and just enough details to be believable. Too little detail and you'll get caught offguard by questions you have no answer. Too much details pose the danger of inconsistencies and cast suspicion since normal people do not remember every tiny details.
Your second paragraph is questionable, though. The machine detection does not measure believability of the lies, rather it measures physical responses. Being intelligent is useless if you start shaking when you tell the lies. I am not saying that there are no people who could escape detection, but it's a different issue altogether.
