So, my guess is that this is a sampling issue. The title could as easily be: “Study suggests that women in male-dominated fields may be above average performers.” Which wouldn’t surprise me at all.
It might be interesting to see it broken down by different kinds of surgery.
There goes my idea of "what about when a woman operates on men?"
Perhaps people are better able to operate on patients of their own sex, and maybe additionally the woman minority of surgeons are better at surgery.
