I'm convinced the most powerful insight that one can have, in order to see the world in the most a dispassionate analytical lens possible, is to fundamentally come to understand where value-judgements enter our human arguments and understanding about the world. These things are what philosophers call normative arguments.
They are everywhere in your thinking.
Every argument you make about politics, economics and culture, has a normative argument hiding in there. No matter how "evidenced-based" or "objective" you think the position is.
When you learn to parse for that, you immediately see through a lot of the narrative-based reasoning traps that people fall into.
But still, no matter how analytical you are, you're going to have to show up with your own normative arguments, yourself. But being aware of them is critical to intellectual honesty.
