I would go a step further and say there is probably a high chance that neurodivergent students are more academically successful, iff they did get to that level of education. And it's not impossible that they are overrepresented in that group of people.
And people may be intellectually gifted, and yet experience strong behavioral and social difficulties. Not that my own observation counts but I've met multiple people on the spectrum who were highly intelligent and "gifted" yet faced more adversity in life, i.e. for social reasons. It's controversial because it directly goes against the idea that we exist in a meritocracy.
People are going to cheat no matter what. To me, it's more important that the people who do need and deserve accomodations are able to get them though!
Which is an unreasonable claim.
I have a disability that impairs many aspects of my life. I was still capable of getting through college and am successful in my career. Having a disability does not mean you can't do academics.
