If there is no good evidence available on a topic the right thing to do is to be uncertain.
I agree. (Did I say something to suggest otherwise?)
The default way [...] is to form your opinions based on meta-analysis.
Given the time and inclination to do the meta-analysis (or someone else who's already done the work), yes. Have you perchance done it or read the work of someone else who has?
How confident are you in that prediction?
Not very.

On this topic it seems like your position is that you know that employers act irrationally and don't hire woman who would perform well. My position is that I don't know whether or not that's a case. That means you have a smaller confidence interval. I consider the size of that interval unjustified.

In the absence of that work being done it's not good to believe that one knows the answer.
I remember seeing a talk of the concept of privilege show up in the discussion thread on contrarian views.
Some discussion got started from "Feminism is a good thing. Privilege is real."
This is an article that presents some of those ideas in a way that might be approachable for LW.

One of the ideas I take out of this is that these issues can be examined as the result of unconscious cognitive bias. IE sexism isn't the result of any conscious thought, but can be the result as a failure mode where we don't rationality correctly in these social situations.
Of course a broad view of these issues exist, and many people have different ways of looking at these issues, but I think it would be good to focus on the case presented in this article rather than your other associations.
