New Study Evokes Debate Over the Ethics of Using Biological Markers to Predict, Preempt Harmful Activity

Friday, March 29th, 2013

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…)

Huffington Post Features Dr. Philip Zimbardo, Famed Revealer of Systemic and Situational Factors Involved in the Emergence of “Evil” and Heroism

Tuesday, March 12th, 2013

Last week, The Huffington Post featured someone whose name should always be in the mix when discussing ponerology: Philip Zimbardo, Ph.D., a man who has spent much of his life investigating the science of what makes people act in ways we might deem “good” vs. “evil.”

In our recent piece about Dr. James Fallon, we discussed the three ingredients that Fallon believes are required for the creation of a psychopathic killer.

These included:

  • Certain structural and functional characteristics of the brain
  • Certain variants of particular genes
  • An environment that triggers the expression of these biological predispositions

While psychopathic killers can cause great harm to a certain number of people, they are relatively rare. The greater danger, from the perspective of society at large, is the emergence of “evil” on a broader scale within systems. And, as Andrew M. Lobaczewski makes clear in Political Ponerology, for that to happen, not only must people with disorders other than psychopathy be drawn into harmful activities, but so must some percentage of biologically healthy, normal people.

Zimbardo’s work has primarily focused on investigating how this latter event occurs – how everyday, average people can end up participating in destructive events.

Zimbardo has been a psychology professor at Stanford University for over forty years. He is best known for leading the team that conducted what has come to be known as the Stanford prison experiment back in 1971. (more…)

Neuroscientist James Fallon’s Work & Life Shed Light on How Psychopathic Killers are Made…and Perhaps Prevented

Tuesday, March 5th, 2013

One of the most challenging and important questions in ponerology is whether conditions associated with reduced empathy and conscience, and thus with increased likelihood of harmful malicious and neglectful activity, are caused by nature (genes, biology, etc.) or nurture (environment, upbringing, etc.)

Most who work in the fields that study aspects of this question take the view that the answer involves some combination of the two.

But this still leaves us with another question. In what proportion do each of these factors contribute in which people?

One remarkable case offers some fascinating insight on the subject.

Dr. James Fallon

James Fallon, Ph.D. is a highly decorated neuroscientist and Professor Emeritus of Anatomy and Neurobiology at University of California, Irvine. Dr. Fallon has several areas of expertise. One is adult stem cells. Another is psychiatry. Specifically, he is interested in the relationships between brain imaging (he has served as Director of UC Irvine’s Human Brain Imaging Center), genetics and various psychiatric conditions, including schizophrenia, depression and addictions.

An Extraordinary Experiment

Aware of his specialties, for many years, Fallon’s colleagues have sent him brain images they wished to have him analyze.

At one point this interchange took the form of an experiment.

Colleagues sent him 70 MRI scans of brains belonging to people ranging from healthy to mentally ill. Included in the batch were scans of brains belonging to killers, including some notorious ones. But Fallon had no idea which scanned brain belonged to whom.

Nonetheless, he was able to identify differences in five of the scans so dramatic that he could recognize them as the markers of psychopathy. And it turned out that he was correct. The five scans on which he zeroed in actually were those from the brains of psychopathic serial killers. (more…)

Research Journal Social Neuroscience Dedicates Special Issue to Brain Studies of Aggression, Violence & Psychopathy

Monday, February 25th, 2013

One of the most important aspects of ponerology – a crucial one in seeking answers regarding why people act (or fail to act) in ways that do harm to others – is investigation into what goes on in the brain when people relate with each other in various ways. We might term such investigation “social neuroscience.”

Well there is actually a research journal by that very name. And that journal, Social Neuroscience, has recently honed in on topics at the very heart of ponerology. Its latest issue – Volume 8, Issue 2 – is a special issue focusing on aggression and violence.

It features an editorial entitled “The social cognitive neuroscience of aggression, violence, and psychopathy” followed by six studies that consider the links between neurological markers and responses and harmful behavior.

Here is a summary of the six studies in this special issue. (more…)
