When I tried to educate myself in neuroscience a few years ago, DSM-V was pretty much universally controversial because of putting stuff into many discrete categories instead of trying to place things onto a few spectra... Such as, suppose, a spectrum of how social a person might be, or how much attention they have. And, of course, many medications are widely recognized to be overprescribed.

I think these sentiments just need some time to get from the academia into the business.
