But for determining truth, both sides are wrong here.
Dunning-Kruger is bad, but so is credentialism and appeal to authority.
Many people with PhD's have had Dunning-Kruger. Someone else mentioned Ben Carson being great at neurosurgery, but not politics.
A PhD doesn't make you infallible.
I am saying this as someone who is taking graduate-level courses and will be pursuing my PhD. When I'm correct, it's not because my future PhD causes reality to magically conform to my opinions - it's because I rigorously looked at the evidence, logic, and formed my own conclusion that better aligns with reality.
Okay but what is good engagement against "follow the science" aside from "I literally DO the science"? Dr. McCreight offered a point and was met with "nuh uh" so at that point it can hardly be called an argument or debate. Do those fallacies honestly matter at that point when one refuses to engage with tangible points of discussion?
Just a branch off thought I had when you said many people with PhDs have had Dunning-Kruger. In general, I think the way the term is used (especially online) is used incorrectly.
Everybody should experience Dunning-Kruger, it's part of the process of learning something. People who use it as an insult should be calling their accusee arrogant instead.
