Plus the article shifts to anti-social and biological behavior instead of focusing on how feeding children a diet rich in fish could prevent violent behavior in teens.
Secondly, Professor Adrian Raine, a leading psychologist at the University of California used magnetic resonance imaging to study the brains of people with less lethal anti-social personality disorders. And he found an 11 per cent reduction in the volume of neurons – so-called grey matter – in their prefrontal cortex compared to the average. I believe that the “third variable” is that they also showed lower heart rates and sweated less when stressed, a sign of blunted emotional responses which could affect their ability to empathize with victims.
