Welcome to mindlevelup: The Book!

This book is intended to be a more beginner-friendly introduction to rationality. Most of the material is sourced from blog posts here on mindlevelup, but there’s also new content!

My goal is for this to be a sort of Schelling Point for newcomers to rationality curious about some of the more evidence-backed ideas. So if you know anyone who’s interested in learning more about rationality, but finds the Sequences too daunting, this might be a very good choice!

Currently, it’s at about 30,000 words and ~150 pages, but that might change with future updates.

The best way to read the book from the Google Doc link, which will get the fastest updates, as that’s the actual doc I use for writing.

For a PDF / other version, I recommend directly selecting “Download As” from the Google Doc link, as that ensures your copy will be the most up to date.

Lastly, of course, you could read it here on mindlevelup. (Which’ll also be behind the Google Doc because editing on WordPress is time consuming.)
