Rove's brain

Fitzgerald might want to look into this:

Habitual Liar Brains Look Different On Scans
Adrian Raine and Yaling Yang have found that habitual liars have more white matter and less gray matter in their brains as compared to less lie-prone people.
The research – led by Yaling Yang and Adrian Raine, both of the USC College of Letters, Arts and Sciences – is published in the October issue of the British Journal of Psychiatry.
… The subjects were taken from a sample of 108 volunteers pulled from Los Angeles’ temporary employment pool. A series of psychological tests and interviews placed 12 in the category of people who had a history of repeated lying (11 men, one woman); 16 who exhibited signs of antisocial personality disorder but not pathological lying (15 men, one woman); and 21 who were normal controls (15 men, six women).
At least a quarter of the temporary employees examined were pathological liars or had antisocial personalities.
… Magnetic Resonance Imaging (MRI) scans found more white matter and less gray matter in the liars. So then are women better liars than men on average? Women also have a higher ratio of white matter to gray matter than men do.
After they were categorized, the researchers used Magnetic Resonance Imaging to explore structural brain differences between the groups. The liars had significantly more “white matter” and slightly less “gray matter” than those they were measured against, Raine said.
… More white matter – the wiring in the brain – may provide liars with the tools necessary to master the complex art of deceit, Raine said.
“Lying takes a lot of effort,” he said.

Rove makes it look so effortless.
