If women know something men don't, men could just ask. That seems much more relevant than testing people's play-acting skills, and we'd actually learn what it was. As in this case women could just publish it and get a paper out of it, I doubt it.

For some knowable things. For others (a) women's self-reported knowledge might be unreliable, (b) women might already be telling men, but this does not get through because men have elaborate justifications for why women's self-reports are unreliable, or (c) the knowledge may be tacit and not easily communicable.
Obviously this applies to any two groups. My guess is that, abstracting from this particular example, most differences between individuals' beliefs is due to a large component of (c.)

Link.
Can this be reasonably explained by self-interest? Female and male economists' views are probably coloured by gender solidarity. Government jobs may be more likeable to women than men because of their recorded greater risk aversion. Regardless of the reason government jobs are more important for women than for men. Also in the US where the study was done middle class white women benefit quit a bit from affirmative action in government hiring.
Politics is the mind-killer probably does play a role in explaining the difference.
First two points are somewhat congruent with stereotypes. Anyone who has run into the frequent iSteve commenter "Whiskey" will probably note that the third point indicates women may not hate hate HATE lower and middle class beta males in this case.
This seems plausible since politics is about applause lights after all, the tribes are what matters not the particular shape of their attire. But might value differences still be behind the gender difference? Maybe some failed utopias I recall reading aren't really failed.
Somehow I think this does not include ideological diversity.
No mystery here. (^_^)
