Trivia: Harry Potter and the Methods of Rationality
- Actor Allusion: Indirectly. There is a reference to Tom Lehrer, of whom Daniel Radcliffe is a big fan.
- Hebrew is mentioned in chapter six.
- Fandom Nod: As a paean to Harry Potter fanfic, there are several.
- I Knew It: Yudkowsky was very impressed by how many people guessed how Harry was going to handle Hermione's trial.
- Schedule Slip: Around Christmas 2011, nearly four months after Chapter 77 was published, Chapter 78 was finally done, but to spare the readers the nerve-wracking wait between its cliffhanger and Chapter 79, the author decided to finish Chapter 79 first. When that one was finished three days later he then decided to finish the whole arc first because his speed had improved so much.
- But three weeks later, he was already finishing chapter 81 and explaining that he was still making backwards edits to all the unposted chapters. So most of the complainers have stopped complaining and asked him to just post more often on his progress.
- Reality Subtext: The case of Amanda Knox, who is allegedly a reader of the fanfic. May also qualify as a Tear Jerker.
- What Could Have Been: An omake chapter explores the possibility of applying the "rationalist" concept to other works of fiction, including The Lord of the Rings, Twilight (which Yudkowsky explicitly states is the premise of Alicorn's Luminosity), and The Lion, the Witch, and the Wardrobe. A brief margin is dedicated to a Gurren Lagann/Warhammer 40,000 crossover, but leaves it simply as:
- Word of God: The author posts on this work's discussion page.
"If there is any character in Methods who is a Self Insert, it is Godric Gryffindor."
- Write Who You Know: Much of Professor Quirrel's characterization was inspired by Yudkowsky's colleague and co-blogger Robin Hanson. The whole "being evil" part is pure fiction, though. (We hope.)
