Just as in our society individuals may have an incentive to do nefarious deeds like robbery or murder, but society as a whole has an incentive to stop it, so it is with science.
And having checked your link, A) the person's theory was overhyped and B) a meta analysis brought it back to earth. Which is evidence that the process of scientific inquiry works.
That's why we know that climate change exists, despite deniers, and that vaccines don't cause autism, despite anti vaxxers having been inspired by a now retracted paper that said it did.
Furthermore, if you want to come to valid statistical conclusions about whether a discrepancy is due to a particular cause (and can't just do a RCT), it's not enough to just ignore plausible confounders until they are "provable". You need to systematically control for all possible confounders.

> What we found is that de-identifying applications at the shortlisting stage does not appear to assist in promoting diversity within the Australian Public Service (APS) in hiring. Overall, APS officers discriminated in favour of female and minority candidates. The practical impact is that, if implemented, de-identification may frustrate diversity efforts.
What's interesting, I suppose, is not that the selected speakers were all men (which could have happened by random chance), but the reaction by the conference organisers to that fact.

I have to laugh my ass off. In reality, boys get 800 on the math SAT at over twice the rate that girls do. That article addressing this by stating "the SAT is hardly a random sample of all students" is complete nonsense.
The idea that smart males and females are produced at the same rate is ludicrous on its face, because female brains are made with the information from two X chromosomes and males with just the one.
Girls and boys mathematical abilities are equivalent.
