The Abridged Guide to Intelligent Characters is a series of shortened excerpts of a minibook-in-progress on How To Write Intelligent Characters. This advice may contain significant but not story-breaking spoilers for Harry Potter and the Methods of Rationality. The minibook assumes that the typical reader has read HPMOR, and the writing advice here is not guaranteed to make sense if you have not read HPMOR. If you’re not already familiar with advice like “Show, don’t tell” then you should read standard books of writing advice like “How to Write Science Fiction and Fantasy“ by Orson Scott Card. The author has omitted all advice that is duplicated in standard writing books.
