I don't know of any magic formula. We'd have to force the change somehow, because it won't correct itself. But the path is unclear, if there is a path at all. The current situation is that most clinical research is performed by MDs/MD-PhDs with no scientific background else than what is taught in medical/doctoral school, i.e. they lack the basics, and are usually more interested about advancing their careers rather than science. That said, systems shape people, and not the other way around.
