The male mind doesn't care as much about the inside of the house as the outside. Our noggins are wired for larger spaces, such as the garage, the driveway, the yard. Sure, some men are neat freaks and homebodies and some women are sloppy and couldn't care less about the inside of their homes. But where biology is concerned, the male and female brains are different.
But the housework study isn't so interested in biological truths. It is more interested in one of its key findings: that the institution of marriage appears to change the division of household labor. In married relationships, even if an egalitarian viewpoint is present, men still report doing less housework than their wives, says George Mason sociologist Shannon Davis.
"Marriage as an institution seems to have a traditionalizing effect on couples -- even couples who see men and women as equal," she says. In other words, marriage itself is the reason women are forced to pick up stinky socks and wipe up the slop in the kitchen after dinner.
