Sandberg: It's safer to be smart

Neuroscientist Anders Sandberg chimes in on the cognitive enhancement debate and notes that intelligence has its privileges:

A fun reference I found last week is IQ in early adulthood and later risk of death by homicide: cohort study of 1 million men, which demonstrates that among swedish males having intelligence above average reduces the risk of being murdered to 27% of the risk among the lower 11%. Why this is so is a bit unclear, but clearly intelligence is health promoting. It reduces injuries and bad driving too.

Just as an aside, high IQ has also been linked to vegetarianism.
