It is known in the science world, that whomever controls the research, controls the outcome. Allowing someone who makes billions off of a product to “test” it will be flawed and biased. It is just common sense.
There is no “neutrality” in science although corporations pay to make you think it is so and always the “Truth” when they lie and cheat to get the desired results. (peer reviewed hockey stick graph) .
Our belief in “studies” should be skeptical until enough studies come out to “prove” something. The trouble is, most corporations control all research and universities with their billions of dollars—so they sell lies half of the time to useful idiots and throw out the results which prove their theory wrong.
Kuhn’s Structure of Scientific Revolution shows the flaw in “normal” science.
Worldview will determine the results in most people....even if they “think” they are being unbiased—which is impossible because of their assumptions (or bribes). Cynical? Oh yes.....it is the nature of man-—Total Depravity!
Anybody who will not release their source data so that other scientists can confirm or refute their conclusions is not practicing science.
That's what climate-change "scientists" do... keep their data secret.
