If you think you don't trust scientists, you're mistaken. You trust scientists in a million different ways every time you step on a plane, or for that matter turn on your tap or open a can of beans. The fact that you're unaware of this doesn't mean it's not so.— Paul Graham (@paulg) July 26, 2021
First of all, people trust airplanes because of their long track record of safety, not because of any claims made by scientists. Secondly, people distrust "scientists" when politics is involved because of course scientists are human and can get corrupted by their political (or religious) beliefs.
And thirdly, the concept of "trusting scientific authority" is wrong, since the bedrock principle of science is distrusting authority. What defines sciences is how often prevailing scientific beliefs are challenged.
