Suicide

This was an interesting result I saw in the BMJ this week: "People who commit suicide have heavier brains at necropsy than controls who died suddenly but of natural causes, a study has found (British Journal of Psychiatry 2000;177:257-61). The authors, all psychiatrists, can't say why victims of suicide have heavy brains, but they think the matter should be investigated further. "

I seem to recall that the volume of the brain, as measured by a PET scan, it proportional to 'g'. Could it be that stupid as suicide appears to be, suicides are cleverer?

I suppose that it could be an artefact of the violent death of an
otherwise healthy person.
