I found this article about 'Thinking in Grey' to be excellent. My highlights are below:
+ We start thinking in rigid categories: War is good. War is bad. Capitalism is good. Capitalism is bad. America is Socialist. America is a Free Market System. We must support our troops. College is useless. College is indispensable.
+These slogans become substitutes for actual understanding, and it’s not as benign as it seems. The slogan isn’t just a shorthand: It replaces thinking for many people, because it’s hard to generate real understanding
+It takes a substantial deprogramming to realize that life is all grey, that all reality lies on a continuum. This is why quantitative and scale-based thinking is so important
+We can re-frame our slogans above: War is awful but history shows it to be occasionally necessary, and a very complex phenomenon. Capitalism is enormously productive but has many limitations”
+If any of these ruffle your feathers, then good. The first step towards thinking in 3D is realizing that you carry many of your cherished positions too strongly.
+It’s only once you can begin divorcing yourself from good-and-bad, black-and-white, category X&Y type thinking that your understanding of reality starts to fit together properly. Putting things on a continuum, assessing the scale of their importance and quantifying their effects, understanding both the good and the bad, is the way to do it.
