lolwut? How is that an important point? I guess noticing general trends in difference of attitudes between the sexes is mildly interesting, but it's a pretty trivial issue.
If 'men and women seem to have, on average, different standards with regard to housework' (presuming men have a 'lower' or 'less fastidious' one), then it would follow that men will do less housework as their standard can be more easily met, while women - unhappy with this standard - will bring it up to the one that they're happy with (from a male perspective she would be creating unnecessary work for herself).
Where I'd disagree is that I would not agree with such a stereotypical difference of attitudes between the sexes - I think we've all met enough female 'slobs' and 'fastidious' males to debunk that.
