The point of all the research academics do is keep their jobs, get ahead on the academic ladder, etc. It has nothing to do with improving things beyond their personal status. This is readily evident if you consider research in social sciences and humanities, most of which is little more than self-pleasure.
I don't agree with that. At least not as a blanket statement.... But then I'm in a public policy school. Maybe much of our work doesn't have much impact, but it is aimed at impact.
