Without trying to explain why this is, back to the stone age, let me say that I think the Technical IQ vs. Emotional IQ has some validity, but I think it has more to do with interest than ability. I have taken advantage of quite a few scripts from sqlfool.com. "That female" has a better grasp of "the details" in SQL server than I do, without any doubt. She's been more interested in it that I have been... for a longer length of time. There are other good examples. I think your hesitation to generalize is a good impulse. At least in this case, I don't think generalization has any usable value. When I'm presented with work that is well formed, organized, and thorough in this field, I don't have a clue as to the sex of the author without checking the name.

With respect.
