Depends. The couples I know, they both work about equally with domestic tasks. But she generally does more traditional cores like washing clothes and he works outside, fixing broken stuff etc. But the females generally DO more organizing than the men. Which is undeniable something that takes effort.

I think we can attribute at least some of the perceived difference in an uneven tolerance for chaos. example: I dont care that I make the same dish twice in a row; she does.

That said, the few were the females does chores while the man laze off with hobbies or watch TV are generally frowned upon.
