Elsewhere I told the tale of my two friends in hard science molecular biology. They do their research at a major medical school in California (Immunology and Genetics)
They simply refuse to accept female graduate students. Or if forced to, they get rid of them as soon as possible.
Asked why so? and I was told that their work is generally less than rigorous, sloppy and wishful thinking in their laboratory books, and just plain out to lunch.
“Good pairs of hands, not so good brains” was a direct quote. “They might make good techs if they were supervised by hard nosed bastards. Otherwise their sloppy thinking would sink a project.”
In both their years of experience, they estimated that 5-15% of their females could make the intellectual cut line they had determined.
Ironically enough, these guys also considered themselves card-carrying liberals.
Interesting, eh?
