I would argue it's actually an educational problem, not an incentive problem. Most people (made up stat) would struggle to name/describe any disabilities beyond immobility, blindness and maybe handful of others. Then add in the lack of tools and aids (in the form of popular references, guides and QA forums) available and you have a problem.
