The one tool we can wield in this information or rather misinformation age is critical thinking. I no longer follow any pundit. I have nowhere near their knowledge in their respective fields, but I can think and ponder whether their views make sense. Robert Reich, Krugman, Brooks, Shields, Shapiro or whomever. See what slant they are coming from, try to understand if they make sense. Immediately afterwards, read about the same topic from someone on the opposite side of the spectrum. Don't get lost in the doomsday world is ending, other side is evil BS. Then hold an opinion, but don't stick to it. Allow it to be malleable and change and try arguing from the other side constantly. I feel like our own ego is partly what let's us join each tribe of thought and we further reinforce it from reading similar viewpoints because we want to be good and right. Sounds simple, but it's so easy to get caught up in it without taking a step back and just thinking about that thought process.
So, that's how you keep democracy alive. Not through simple education where you reiterate facts, memorize or follow directions, but through improving critical thinking which is slowly worsening in college and high schools. In a conversation with a classmate, we reminisced how in 3rd grade we learned how to spot bias in news articles, practicing for months. I feel like that's disappeared too.
