It's a theory that many women have held for years.
And now a study has revealed men really are the more stupid sex.
Analysis of the Darwin Awards - an annual review of the most foolish ways people have died - has found almost 90 percent of the accolades were 'won' by males.
Worthy candidates include a terrorist who opened his own letter bomb, and a man who attempted to travel by hitching a shopping trolley to a train.
It is named after Charles Darwin, the scientist famous for the theory of evolution.
Nominees have to improve the gene pool by eliminating themselves from the human race using foolish methods.
Examples include the man who shot himself in the head with a 'spy pen' weapon to show his friend it was real, and the thief attempting to purloin a steel cable from a lift shaft - and unbolted it while standing in the lift which then plummeted to the ground, killing him.
Of 332 independently verified nominations, 14 were ruled out of the analysis because they were shared by male and females - usually adventurous couples in compromising positions.
Of the 318 valid cases remaining, 282 (88.7 percent) were awarded to males and just 36 to females, a gender difference entirely consistent with male idiot theory (MIT) that states men are idiots and idiots do stupid things.
Writing in the British Medical Journal, the researchers said it is puzzling men are willing to take such unnecessary risks - simply as a rite of passage, in pursuit of male social esteem or solely in exchange for 'bragging rights'.
研究人员发表在《英国医学杂志》（British Medical Journal）的文章称，男人仅仅把做蠢事作为一种仪式，愿意冒这种毫无必要的险去追求社会尊严，或者仅仅以此换取“吹嘘的权利“。这真令人困惑。“
Dr Dennis Lendrem, of theUniversityofNewcastle, said: 'Idiotic risks are defined as senseless risks, where the apparent payoff is negligible or non existent, and the outcome is often extremely negative and often final.
英国纽卡斯尔大学（the University of Newcastle）的丹尼斯· 伦卓蒙（Dennis Lendrem）博士说：“愚蠢的冒险被定义为无意义的冒险，这些冒险的收获极小甚至没有，结果也通常是极其不好而且无法挽回。“
