ADHD is objectively a bundle of true deficits, not just a set of traits society frowns on. Certainly these deficits weren't as much of a disadvantage in early human evolution, but if you can create metrics and show that people with ADHD perform worse at some generic tasks vs. average human beings-- and you can, we have-- this is not just a world that has been created that is inhospitable to them. The ugly thing I've found, which accords with what you have said here, is that the best treatment for me is as many hours of sunshine as possible and several hours of vigorous exercise a day. (Thanks for teaching that, Marine Corps.) But of course there are very few jobs with security, brain exercise, and mobility that give me this, and essentially no jobs that are compatible with it (that it is, where I could take this time off per day and still retain a job). So of course I use medication and stick with jobs that drive me nuts, jobs that are terrible for me but pay well. I feel for the ADHD people who weren't gifted as decent a brain as mine, as if it weren't for that I doubt my employers would have been as indulgent of my other flaws from ADHD. |
There is doubt that a set of behaviors which is so prevalent in the population is just an accident and a disease. Evolutionary pressures exist to optimize gene expression ratios in a population. Put differently, when a certain gene becomes rare in a population individuals with that gene have a significant advantage in life and reproduce more – when the same gene becomes over prevalent individuals with that gene have a significant disadvantage and reproduce less. There are traits which have pressure to be a certain proportion of a population.
ADHD or whatever else you may call it could very well be that. Ancient societies which had a small proportion of a certain kind of person thrived because their different behavior made them successful. It doesn't have to be a disease to not fit in to a certain society.
