Karma: 509

I’m a rising junior at the University of Chicago where I co-run the EA group, founded the rationality group, and am studying philosophy and economics/​cog sci. I’m largely interested in formal epistemology, metaethics, formal ethics, decision theory, and I have minor interests in a few other areas—I think LessWrong ideas are heavily underrated in philosophy academia, though I have some contentions. I also have a blog where I post about philosophy (and other stuff sometimes) here: https://​​substack.com/​​@irrationalitycommunity?utm_source=user-menu.
