You’ve hit the key point...To the Left, “science” is what they say it is, based on the political agenda...
And since government and foundations are the source of grants, the mother’s milk of science, there will always be “scientists” (aka whores) who share the desire for a certain outcome willing to work backwards to “prove” it in exchange for payment...And if the “scientists” already share the underlying bias, then so much the better...
This is not a general indictment of science or scientists; the majority are honest and seeking the truth...It’s an acknowledgement that the afore described whores exist and are willing useful idiots of the Left...
Lysenkoism: After Trofim Denisovitch Lysenko; describes the manipulation/distortion of scientific process as a way to reach a predetermined conclusion dictated by an ideological bias, often related to social or political objectives.
