In a high stakes, challenging environment, every human weakness possible becomes a huge, career impeding liability. Very few people are truly all-around talented. If you are a Stanford level scientist, it doesn't take a lot of anxiety to make it difficult to compete with other Stanford level scientists who don't have any anxiety. Without accommodations, you could still be a very successful scientist after going to a slightly less competitive university.

Rising disability rates are not limited to the Ivy League.

A close friend of mine is faculty at a medium sized university and specializes in disability accommodations. She is also deaf. Despite being very bright and articulate, she had a tough time in university, especially lecture-heavy undergrad. In my eyes, most of the students she deals with are "young and disorganized" rather than crippled. Their experience of university is wildly different from hers. Being diagnosed doesn't immediately mean you should be accommodated.

The majority of student cases receive extra time on exams and/or attendance exemptions. But the sheer volume of these cases take away a lot of badly needed time and funding for students who are talented, but are also blind or wheelchair bound. Accommodating this can require many months of planning to arrange appropriate lab materials, electronic equipment, or textbooks.

As the article mentions, a deeply distorted idea of normal is being advanced by the DSM (changing ADHD criteria) as well as social media (enjoying doodling, wearing headphones a lot, putting water on the toothbrush before toothpaste. These and many other everyday things are suggested signs of ADHD/autism/OCD/whatever). This is a huge problem of its own. Though it is closely related to over-prescribing education accommodations, it is still distinct.

Unfortunately, psychological-education assessments are not particularly sensitive. They aren't good at catching pretenders and cannot distinguish between a 19 year old who genuinely cannot develop time management skills despite years of effort & support, and one who is still developing them fully. Especially after moving out and moving to a new area with new (sub)cultures.

Occasionally, she sees documents saying "achievement is consistent with intelligence", a polite way of saying that a student isn't very smart, and poor grades are not related to any recognized learning disability. Really and truly, not everyone needs to get an undergrad degree.
