Why blame me? It was all my brain’s fault
In the courts, as in the trial of serial rapist and murderer Bobby Joe Long, brain-scan evidence is being invoked in support of pleas of diminished responsibility. The idea is abroad that developments in neuroscience – in particular the observation of activity in the living brain, using techniques such as functional magnetic resonance imaging – have shown us that we are not as free, or as accountable for our actions, as we traditionally thought.
Though they failed to cut much ice in Long’s case, arguments that blame lies not with the defendant but with his overactive amygdala (supposedly responsible for aggressive emotions) or his underactive frontal lobes (supposedly responsible for inhibiting the expression of such emotions) are being deployed with increasing frequency. If our brains are in charge, and bad behaviour is due to them, our attitude to criminal responsibility, to punishment (the balance between rehabilitation and retribution) and to preventive detention of individuals thought to have criminal tendencies may all have to change.
