Every time someone mentions “settled science” I ask them if eggs are good or bad for you.
Even numbered day today so they’re good today.
Right. There is no such thing as “settled science”. I believe it was the late Charles Krauthammer who said: If it’s science, it’s not settled. And if it’s settled, it’s not science.
And at one time scientists were encouraged to challenge established beliefs. Continually challenge! No more. If both Al Gore and Greta Thunberg say so, it must be true. Case closed. Anyone who disagrees is a “wrecker” - to use an old Soviet term.
Or coffee.
Or steak.
Or a wide variety of conventional vitamin supplements.
The simple fact is - as you alluded to - that the “settled science” changes every time a new “study” says something different (and many of those “studies” are - just like the Hydroxychlorquin tests recently - designed from the beginning to produce a particular result).
