Today I was reading through my new tome, “The Anatomy of Violence” and came across an interesting observation. The author noted that the septum pellucidum, a section of the brain that has fused tissue in normal people, is often found to be separated in psychopaths and antisocial types. I immediately went and examined an MRI of my brain done years back during my vestibular issues. And I was able to confirm that I am probably not a psychopath—my tissue is fused.

It struck me that this opens up an interesting situation. This unfused tissue seems to be a marker for psychopathy—it doesn’t confirm the person is a nut, but it increases the odds. As medical scanning gets cheaper will employers start checking applicants’ brains for such markers? Will potential romantic partners ask each other for MRI scans to rule out problem relationships? Only time will tell…
