Here’s a quite fascinating L.A. Times article on pedophilia that veers towards what I’ve long suspected – that pedophilia is a sexual preference wired into a person’s brain. (Whether that means it’s innate or not is another question though I suspect that it is.) Scientists are delving into this difficult question and making interesting observations. Like…

Among the most compelling findings is that 30% of pedophiles are left-handed or ambidextrous, triple the general rate. Because hand dominance is established through some combination of genetics and the environment of the womb, scientists see that association as a powerful indicator that something is different about pedophiles at birth.

“The only explanation is a physiological one,” said James Cantor, a leader of the research.

Researchers have also determined that pedophiles are nearly an inch shorter on average than non-pedophiles and lag behind the average IQ by 10 points — discoveries that are consistent with developmental problems, whether before birth or in childhood.

In a 2008 study, Cantor’s team conducted MRI brain scans on 65 pedophiles. Compared with men with criminal histories but no sex offenses, they had less white matter, the connective circuitry of the brain.

The evidence also points to what Cantor explained as “cross wiring”: Seeing a child sets off the same neural response that men typically experience around an attractive woman.
