Categorizing The Causes Of Bad Things In The World

November 17, 2025

What causes bad things? It sounds like a huge question, but maybe it's not as big as it seems. Here's my updated/improved list of high-level causes of bad things in the world. Note that these are not mutually exclusive categories. I've also added some potential solutions for each cause. I'd be interested to know: what is missing from my new list of causes of bad things and potential types of solutions? Thanks to those of you who commented on my prior version!

I stood there pondering t...

Understand how other people think: a theory of worldviews

June 29, 2022

This piece was coauthored with Amber Dawn Ace. A libertarian, a socialist, an environmentalist, and a pro-development YIMBY watch an apartment complex being built. The libertarian is pleased - ‘the hand of the market at work!’ - whereas the socialist worries that the building is a harbinger of gentrification; the YIMBY sees progress, but the environmentalist is concerned about the building’s carbon footprint. They’re all seeing the same thing, but they understand it differently because they ...
