This is kind-of-sort-of in response to HermeticDancer's thing about ISTJs (since I, and many INTPs, do exactly the same thing as ISTJs in that respect):
I saw something (maybe in a Men are from Mars-style book? maybe from my INFJ mother?) with regard to fixing problems, and it was divided by gender as follows.
Supposedly, when men tell women about an issue that bugs them, the women will essentially say "Oh, jeez, that sucks" and pat them on the shoulder or something to that effect. When women tell men about an issue, however, the male response will be an attempt to fix the problem, when the women simply wanted them to express sympathy.
I disagree with the idea that these two behaviors are gender-specific. After all, I do the "male" thing regularly, and yet I'm not a guy. I think it's actually an F vs. T thing. (when people have relationship/emotional issues to solve, I have no idea how to approach them. Yay for inferior Fi!... not really.)
