It's actually you who doesn't understand probabilities. If a woman is twice as likely to make a discovery but women are only 5% of researchers, then it's both true that:

1. most discoveries are made by males

2. it is reasonable to give larger weight to new female-done research

contradicting you point.

But you pulled those number out of thin air. The fact of the matter is that if I pick one research paper at random out of all the papers written by men and I pick another research paper at random out of all the papers written by women the former will be of higher average quality.

Did you just pull that out of thin air?

You will find it beneficial to learn about "selection bias".
