Here is KB’s incisive testimony to Parliament in April 2022, in her role as Social Mobility Commissioner for HMG. I quote from the BBC website: (Recall that 16% of girls at Michaela were doing physics A level as opposed to 23-24% nationally, is about 50% more in relative terms nationally are choosing physics than at Michaela)
^Just from my own knowledge of these things, physics isn’t something that girls tend to fancy. They don’t want to do it.
I just think they don’t like it. There’s a lot od hard maths in there that I think they would rather not do. That’s not to say there isn’t hard stuff to do in biology and chemistry - there is, but it’s not mathematical.^
Asked to explain [further] why she thought girls would be less likely to make the choice [of doing physics] she responded:
^I mean I don’t know. I can’t say - I mean I’m not an expert at that sort of thing.That’s what they say.
We’re certainly not out there campaigning for more girls to do physics - we wouldn’t do that, and I wouldn’t want to do that.
I mean, I want them to do what they want to do^.
A bright child could have provided more compelling testimony. Above, @noblegiraffe did.
I also want girls and boys to do what they want to do. But the statistics on suboptimal GCSE science preparation (I quoted above) and lagging physics uptake by girls at Michaela, together with KB’s complete lack of interest in exploring any of this, strongly suggest bias, a profit motive or both.
By now I have sourced my opinions rather credibly, @Ddakji . I am still interested in your sources as requested above. In HE STEM we have put rather a lot
