You know that “learning disability” isn’t a synonym for “stupid”, right? We neither call people who are less academically able “disabled”, nor are disabled people necessarily less able to work academically (apart from some more debilitating mental disorders, which would be a disability). In fact, it’s quite the opposite: the word “disability” exists _precisely_ to distinguish “intelligence” – which is what the university is selecting for – and other characteristics, so in theory intelligence and disability are entirely orthogonal (apart from the exception I mentioned).

Of course, understanding what disability actually is requires considering each learning disability separately, which is something this article unfortunately fails to do. We can do this though:

- Anxiety and depression: I see no reason why this should decrease somebody’s intelligence, so the fact that there are elevated rates of such people at top universities does not seem odd. Since these are treatable conditions, they won’t necessarily affect the ability for a student to become an effective researcher.

- ADHD: This condition is marked by a lack of ability to focus, which is a property unrelated to intelligence. Some very famous mathematicians like Paul Erdős likely had ADHD, demonstrating that it’s not necessarily true this condition makes one a worse researcher.

- Autism: Does not necessarily reduce intelligence. We can look at professional mathematicians and see that a lot of them are autistic.

- Chronic pain, migraines, etc: Unrelated to intelligence. It’s possible this will decrease one’s ability to be a researcher, but if one is able to complete University at all, it’s likely not that severe.

I mean, I could go on, and of course there will be a couple of counterexample. However, it is still the case that generally speaking, “learning disability” and “stupid” are different things, and therefore there is no reason to expect that there would be lower rates of learning disabilities among those who are highly academically skilled.
