IQ and mortality

A long-term study of more than 10,000 people by researchers at the University of Helsinki looked into the links between IQ and early mortality. The study found that people with a low IQ when they were 11 were more than twice as likely (3.4% vs 1.7%) to die as those with a high IQ. Socioeconomic status had only a minor role in explaining this but more influential were whether parents took an interest in their children's education (if they did this reduced early mortality) and childhood problem behaviour which increased the risk of an early death.
