One of the “holy grails” of ponerology – and an achievement that will inevitably force us to confront extremely challenging ethical dilemmas – is an improved ability to predict harmful behavior before it happens.

Dr. Kent Kiehl of the Mind Research Network has been one of the more active researchers investigating what we can learn from brain imaging of psychopaths. And he and colleagues have recently published, in the Proceedings of the National Academy of Sciences of the United States of America, a study entitled “Neuroprediction of future rearrest.”

The study involved having 96 soon-to-be-released male prisoners perform computer tasks that required quick decision-making and inhibition of impulsive responses, while their brains were observed using functional magnetic resonance imaging (fMRI). The researchers focused in on the brain region known as the anterior cingulate cortex (ACC) and found that, when controlling for other known risk factors, those prisoners with less ACC activity than their fellow study participants were about twice as likely to be rearrested within 4 years of release as those with higher ACC activity.

We’ve already mentioned, in previous stories, that reduced cingulate cortex function is associated with psychopathy and has been identified in some violent criminal offenders.

The question is, as we zero in on markers like this – whether they be certain anatomical or functional characteristics of the brain, particular genetic features or anything else – what is the most ethical way in which to use this knowledge? (more…)

One of the most powerful facts that I may have ever learned is that psychopaths differ biologically from other people. I remember the epiphany I experienced as soon as I internalized this fact, quickly realizing the profound implications it had for everything from psychotherapy to activism to day-to-day life.

When I wrote my detailed page about psychopathy, I made sure to include information about some of these biological differences. Many of them have to do with the ways in which psychopaths’ brain structure and function diverge from that of others.

Recently, a new study was published adding to this important and growing mass of findings. (more…)

One of the most pressing and controversial questions in ponerology is this:

Are there any biological markers by which we can identify people likely to harm others?

For example, as Dylan Stableford of Yahoo News puts it:

Can you spot evil in an X-ray?

Stableford’s article, entitled “‘Dark Patch’ Visible in Brain Scans of Killers and Rapists, Neurologist Claims,” tells of University of Bremen neurologist Dr. Gerhard Roth’s claim that, indeed, we can.

In fact, Roth claims to have identified “the region of the brain where evil is formed and where it lurks.” (more…)
