Harry Potter and the Methods of Rationality is a Harry Potter fanfic written by Eliezer Yudkowsky. It is intended to tell an entertaining and intelligent story, parody some of the aspects of Rowling’s wonderful world, and help spread rationality, all at once. To do so it takes the basic elements and characters from the cannon Potter series but re-imagines them in a world where Harry was raised in a loving household as a child prodigy. It is utterly delightful.
I have made a mission of bringing this work into audio format, so those who prefer can listen to it rather than read it.
