The scientific process and scientific knowledge itself have been systematically corrupted by money power and its corollary: political power.
The good news is, the corruption has become so blatant and absurd that more and more scientists and non-scientists are becoming aware of it, and incorporating it into their understanding.
Rational reductionism has been curtailed. Microscopic focus on one's own immediate discipline is slowly being pulled back, and lines of communication between disciplines are opening up again.
