Um, the point is, dare I say this, that there's very hard science and there's soft science. There's findings which are highly testable, repeatedly, and there's findings which are verging on the non-reproduceable. And whilst science tends to self-correct, sometimes, just sometimes, it can take decades for that self-correction to take place, simply because as you say, it is impossible to remove any bias and error all the time, yet science as a practice must go on.
We are just now, for example, a big example, witnessing a 100% reversal in the thinking behind dietary advice which was the basis for public health advice for the last 50 years. It seems it was soo wrong, that it actually created the epidemic of obesity, diabetes, and maybe even dementia. But this correction is ongoing, and we'll probably need another 50 years to know whether this correction is actually correct.
And it was all science. Albeit, given the limitations of what you can do to people in a lab, it was all soft science, but despite it being soft, the authorities and people in charge still pushed it as pretty definitive and correct. See, that's risk.
Put aside all the politics and questions of morality and ethics and whether humans are too stupid to do the right thing, there is always risk that the big theory is wrong, dead wrong, and that it will have consequences. And when you look at what things like, "97% of scientists are in consensus" are actually based on, you can see it is being oversold, for the sake of "saving the planet".
We cannot, well some people do, rule out the bias of "expert bias". It happens. We know it happens, from time to time. Especially when there is apparent consensus. I used to believe global warming 100% and assume it was all correct, because I normally trust science, but then started to wonder why people were touting consensus and virtual certainty.
Science, the one thing is needs to be in practice, is self-correcting, but once people declare consensus and virtual certainty, we can no longer know whether it can be trusted because that one thing, self-correction, it being open to question by anybody, "on the word of no-one", as the motto used to go, goes out the window.
It cannot self-correct if any dissenting scientists gets lambasted as deniers.
It may be right it may be wrong. Wait another 100 years to find out.
Act in the meantime as you see fit. May the consequences be on your head.
