@strypey @tootbrute I wish there were a neuroscience-informed solution, but realistically I think it comes down to better education in critical thinking skills and considering individual claims in a broader context.
But in the end, I think it's the human condition to want to share information with each other, and to look to people we trust as sources for that. We all do it, and we all sometimes repeat bogus information as a result.
I genuinely think that our best solution is to do what you did and correct when it happens. Most people get their egos wrapped up in "being right" and will refuse to admit if they realize they've said something wrong. A lot of people get furious if they're confronted with evidence they were wrong. Being able to say "Oh, oops, I thought this was true but turns out I was mistaken!" is rarer than it should be. I think we need to normalize it, and I try to call it out for the praise it deserves whenever I see it. That's the best solution I've come up with.
