To GSPaul's point, I love the idea of a certification process, but I wonder whether it will have any impact. Some of the people who get sucked into conspiracy theories simply don't know any better, but a good number of those conspiracy theory folks actively distrust ANY sort of institutional source. (I'm married to one of the latter types, much to my frustration. He has plenty of other good qualities, but this is a glaring problem.) I can't tell you how many conversations I've had with him where I ask why he would rather believe some contrarian typing out completely baseless drivel in his basement rather than scientists with actual educations who pretty much universally agree on the same things, and he has no answer. To him, it seems like everything is some sort of conspiracy (COVID-19 included-ugh), no matter how apparent it is to more science-minded thinkers that there is no unity of interest among the people advancing the actual science, or the countries involved in the so-called conspiracy, and therefore no profit-minded conspiracy is even remotely possible. He seemingly can't be swayed.
I don't want to be a wet blanket by suggesting that the certification might not help. I just wish there was some way to prevent the B.S. manufacturers from creating their drivel, but freedom of speech and all that, and they are motivated by profits so they won't stop of their own accord.Â
