When you work a particular field, and have acquired a certain level of knowledge and expertise, it’s a lot easier to see who has taken time to try and understand something and who is just repeating headlines or media rage bait because it confirms their own bias.
When someone favors what they saw on YouTube over multiple research studies or industry reports or even government reports, I think it’s fair to say they lack intellectual curiosity and are not serious enough to discuss or debate in good faith.
There’s a difference between fact and opinion and there are a lot of confidently incorrect people.
