Re: "scientists"
Political considerations affect all sorts of research. I have a pal in the Geography Dept of one of the UK's best known universities who tells me that even to propose research looking at the likely extent of global warming (not denying it, you understand, just looking for some numbers) is seriously career limiting. Likewise it is politically impossible to research whether parental behaviour leads to ASD/ADHD and so on in children, or whether children who go to nurseries do better than those raised at home.
And so we end up with the nonsense of "neurodiversity" when in the overwhelming majority of cases there isn't a shred of evidence that there is - in computing terms - a hardware error rather than a software one.
