Brain size linked to violence

BBC News:

Men with a deficiency in part of their brain are prone to rage and violence, research has found.

Men with a personality disorder underwent brain-imaging which showed they suffered from a lack of nerve cells in one area of their brains.

The cells - equivalent to about two teaspoonful's worth - were missing in the men, who had all committed serious, violent crimes and had psychopathic personalities.

They all suffered from Antisocial Personality Disorder (APD), which is characterised by irresponsibility, deceitfulness, lack of emotional depth and life-long social behaviour.

Their brains were deficient in the prefrontal cortex, an area thought to be central to children's ability to learn to feel remorse, conscience and social sensitivity.

Now I wonder when and if research will show if this specific "deficiency" is more apt to be found in one (ethnic) group as compared to another...

I imagine by that time the PC crowd will have done everything possible to prevent funding of such research.
