Yeah, I mean, even just basic critical thinking. I still remember a history class when I was around 13 where the teacher told us that all information is biased.
And then she went through a number of different books and newspapers from across the political spectrum and had us talk about how the information might be biased or what narrative the writer was communicating.
Just one class. And it completely changed the way I consumed information. I wonder how that would be received in schools today.
