A related factor I've noticed is that at university at least, a diagnosis often gets you benefits like extra time for exams and some more leeway in terms of submission deadlines for assignments. Which I'd imagine creates somewhat of an incentive to exaggerate even a diagnosis that doesn't actually meaningfully affect one's ability to finish an exam within the normal timespan. I've seen an example of both kinds of cases, one student who clearly had ADHD, but was also clearly putting in the effort rather than seeming to abuse the benefits, and a roommate who just seemed to care more about gaming and used his diagnosis as an out for every responsibility even when the rest of us roommates tried to help him out. So, while I am not in a position to judge who deserves or does not deserve those benefits, I wonder if that has contributed to mental illness becoming a bit of a badge.
