Proving something incorrect is proving proving the negative. That’s not how people engage in good faith argumentation.
I’ll add, a traditional definition of “incorrect information” would primarily focus on factual accuracy over motivation.
Why is it necessary to prove intentionality to prove incorrectness?
All of this is before we acknowledge that you will never accept something as proven false, as proven intentional, or as proven harmful.
Your standard is meaningless because it’s both incoherent and unmeetable.
It’s also characteristic of arguments like this and why the ‘bullshit asymmetry’ concept exists. Trying to meet it is a distraction that simply serves to give your argument credibility because people engage with it in trying (hopelessly) to meet your asymmetric epistemically standards.
What are you talking about? If you claim something is dangerous and want it removed, you better have god damn compelling evidence of the "danger".
Explain what the danger is, and how it is manifesting.
And intentionality is absolutely relevant to this, considering we are essentially judging a conversation between two people. Does the same conversation in a bar constitute misinformation? When does it go from conversation to declaration? When does opinion become misinformation?
I'm not currently interested in whether what they're saying is true or not, I'm interested in whether it can be considered misinformation in spirit of the meaning of the word. If their intention is to discuss something sincerely, then it's not misinformation - it's opinion.
