Yes, and the researchers aren't even considering the possibility that these women sound incompetent when talking to men, because they actually, comparatively, are.
They discount the most obvious explanation without even testing for it, and expect to be taken seriously. What a joke.
I was responding to your post: Yes, and the researchers aren't even considering the possibility that these women sound incompetent when talking to men, because they actually, comparatively, are. The researchers were investigating how much of the perceived competence difference was real and how much was a difference in perception only. So they controlled for actual differences, and found a large difference in the way equally-competent men and women are perceived.
