Yeah you're right. I think part of what I was wondering was whether it does make sense to group those 2 things under one heading, or just how strongly they're correlated.

Now that you mention it, I seem to recall reading on Yvain's blog that he's also hyper-sensitive to negative criticism, so there's another data point for it not being tied all that strongly to gender.
