Some parts of science became political. The goal seems to convince a population, not determine what is true or not.
So if you extract one field which is extremely corrupt, with practices that would seem obvious to anyone who studied Stalin, which soils the ideas and principles of sciences, and another fields rejects the idea of denouncing the first field: that demonstrates that they are both politicized sciences. Covid science, climate science and social sciences all three ask you to “trust the science” and use authority to become right.
Meanwhile a researcher who is funded by private companies for technical advances, generally produces good science. They don’t usually need to jail their opponents.
