The Brains Of Liars

Are wired differently:

One experiment measured the brain structure of pathological liars, and compared it to normal controls — more specifically, the ratio of gray matter (the neural tissue that makes up the bulk of our brains) to white matter (the wiring that connects those brain cells). Liars, it turned out, had 14% less gray matter than the controls but had 22-26% more white matter in the prefrontal cortex, suggesting that they were more likely to make connections between different memories and ideas as increased connectivity means greater access to the reserve of associations and memories stored in gray matter. “Intelligence,” it turned out, wasn’t correlated with dishonesty — but creativity, which we already know is all about connecting things, was.
