The writers put forward a case for physiological links to crime. This is no claim to physical determinism, no suggestion that there are criminal types who can be recognised by the bumps on their heads or the height of their brow ridge. Rather they look at arguments associating some forms of brain damage with dramatic behavioural and personality change, and conclude that there are clear links between brain injury, even relatively minor damage, and subsequent violent behaviour.
Moir and Jessel tackle a complex subject with clarity and intelligence: they communicate ideas about the working of the brain without talking down to the reader and without making the subject obscure or boring. They also handle much of the physiological evidence with conviction.
However, there are problems in their arguments. While there is an excellent contribution to the analysis of violent crime here - and there is strong evidence of a physiological cause in the specific area of psychopathy - their analysis is weak in areas like domestic violence, where much of the pathological behaviour could well have been learned.
If violent crime is related to brain damage, it makes change, reform, or rehabilitation doubly problematic (and I speak as a Probation Officer). What are the treatment options? What are the moral issues - if someone commits a crime because they have been brain damaged, can they be held to be responsible? Can they be found guilty?
A curate's egg of a book - very good in parts, but not entirely convincing, and with one or two major gaps which need filling or explaining. Nevertheless, a stimulating read for anyone interested in or involved in the field of crime.
