When we abandon the scientific process and choose whatever conclusion best suits our whims, preferences, or proclivities, the underlying scientific reality doesn’t stop being true. We simply suffer the consequences that come along with choosing a less-than-optimal path for dealing with the very real problems that we’re facing.
I can’t help but think of the film The Death of Stalin (itself pulling from the reality of the time) where they tried to find a doctor who could save his life only to realize they purged all the good doctors.
Yeah classic brain drain scenario if they really do gut the NSF. Most academics draw public funding for projects even if they work at private institutions. Most of the good ones have opportunities to leave to do the same thing overseas less a couple of the US-specific humanities.
