A study showed Dementia brainscans heavily correlating with a form of Plaque. For decades people believed it, but then it was debunked. Someone expressing disbelief in it before the debunking would not have been “flying in the face of everything we know about logic.” They would have been right.
A researcher made a study where Aspartame used to sweeten Gatorade correlated with fast developing terminal cancer in mice. The researcher who developed Aspartame shot back by saying they fed the mice daily with the equivalent to 400+ Gatorades. Of course, a French study later showed at large scales people who consumed aspartame were slightly more likely to develop cancer in the following decades, but the outcome was still preferred to the consumption of sugar. This is an example that is much more clearcut in the favor of science, but I think there is still room for skeptics to express doubts.
I think talking about these things in a welcoming environment can both alleviate certain less scientific beliefs while also giving a great idea of how the general public views certain topics. Also it’s fun. There is a guy in here who thinks maybe a dude can fight a bear, not that they should.
