You have to know that isn't true, which makes this a great example of why people are frustrated about discussing anything 'political' in the workplace.
If you see similar patterns across many different cultures, including ones considered to be more gender-egalitarian, I would have honestly thought the conclusion would be, in fact, varying interests.
Or do you think there are no biological differences (on average) between men and women, in which case, I can provide you with large, multi-national studies that come to a different conclusion.
I can see how there could be debate about how much the difference is, and what the causes of it are, but "you have to know that isn't true" seems like saying "Come on, everyone knows the world is flat, stop arguing in bad faith".
I know it is true, by looking at empirical data. Can you cite data that support your conclusion?
