Researchers from the north-east of England noted that men are already well known to be much more likely to engage in risk-seeking behaviour and be admitted to A&E as a result.
But in an effort to explore "male idiot theory" (MIT), they examined the verified winners of the Darwin Awards, given to people who die in particularly, sometimes spectacularly, stupid ways and do humanity a favour by removing themselves from the gene pool.
One particularly deserving winner was a would-be terrorist who opened his own letter bomb after it was returned to him when he didn't buy enough stamps.
According to MIT many of the differences in risk seeking behaviour, emergency department admissions, and mortality may be explained by the observation that men are idiots and idiots do stupid things.
There are anecdotal data supporting MIT, but to date there has been no systematic analysis of sex differences in idiotic risk taking behaviour.
