And it's this: does anybody know if any active scientists have changed their mind about the whole hypothesis from doubters to believers? You can find stories of scientists who originally were advocates, like Judith Curry, but then after more research changed their mind and are now labeled "deniers". Most seem to be people who were well established and safe from being fired, like Curry, who had tenure, and has said that she would not have dared to speak up if she hadn't, if she had been just in the beginning stages of her career, because saying what she is now saying would have made her unemployable in the current era.
But the main question is pretty much this: how many scientists, especially well respected ones, have gone from advocates to "deniers" after studying the hypothesis longer, compared to how many have maybe gone from "denier" to advocate?
Because all you can easily find online are all in the first group. And if there are more of those, or especially if there are none of the latter type, that certainly would say something about the whole thing.
And could be used as a point in arguments with the staunch believers you have to deal with in your life.
Humans are humans. If one has to choose between getting hired to do something he got into debt for and used years to learn, vs ending up working in Starbucks or something, most will swallow their doubts and just keep their mouths shut and do what seems to be wanted of them by their prospective employers.
I have known some people with university careers, and the pressures to not to rock the boat, in any way, seem to be pretty harsh, so I don't personally really blame any of the lower tier types, the main guilt is with the top level politicians, bureaucrats, and the few career scientists who have used the thing for their own benefits, and to gain power, just because they figured how they could use it, even if they probably could have had decent enough careers and lives without resorting to hoaxing.
And currently the whole structure for doing science is toxic. The money comes mostly only from people who will want what they can use for their benefit, and will actively crush what might be damaging to their careers. You have people who have been scaring the public for years about climate change - or whose bosses are those people - deciding who gets the funds for studying climate, and you damn well know where those funds will go.
This bloody well has to change if we want to get more serious science again.
