Not persuasive on psychopathy?

Professor David Pilgrim on a recent Horizon offering, 'What makes a psychopath?'

04 September 2017

This was a Curate's Egg of a programme. The 'good in parts' bits included tracing how un-empathic children can become anti-social adults. Also a useful discussion was started about the tendency of politicians to manifest psychopathic tendencies. The pragmatic and rational aspects of those called 'psychopaths' was illuminated by the moral dilemma of when a crying baby should be killed in order to protect a group from certain death. Most of us would be angst-ridden in that terrible scenario, but 'the psychopath' would glibly kill the baby out of self-preservation.

However, despite the coherence of individual academic contributions, the overall message of the programme was incoherent and offered the viewer certainties that are not warranted. Four US felons (three murderers and a child sexual offender) were interviewed to illustrate 'the psychopath'. However, not one of them had actually received the label from a professional assessment. If 'the psychopath' does indeed exist then why not interview the real thing? This omission was not explained.

The 'essential psychopath' narrative in the programme implied homogeneity and a single linear form of causality, even though at times it was admitted that in individual cases there was ambiguity about genetic proneness and brutalised childhoods. Brain slices with their warm and cool areas now are favoured by the mass media, not just professional neuro-reductionists. These were offered to show how the limbic system of 'psychopaths' was markedly different. Although the ambiguity about cause and effect was noted, it was not considered a reason to park our confidence in brain-slicing.  

Really important pre-empirical questions were not addressed in the programme. For example, the notion of 'psychopathy', started by Hervey Cleckley and developed since then most extensively by Robert Hare, does not appear in either DSM or ICD categories. Not only does Hare insist psychopathy is a dimension not a category, he selectively weaves a description from features of Anti-Social Personality Disorder, Histrionic Personality Disorder and Narcissistic Personality Disorder. The last of these appears in DSM but not ICD. Surely we needed an academic viewpoint about this conceptual confusion instead of alleged certainties about 'the psychopath'? The programme was silent on this point.

The term 'psychopath' refers to people we do not like because they have done really horrible things and do not seem to care. 'Scientific psychology' may have something to offer beyond ordinary moral judgments but if it does, then this programme did not persuade.
