Faint memory: didn't they have a statue in plate armor?
Yup. For that matter, Sir Cadogan is fairly unambiguously described as a mounted knight.
On the other hand, I'm not sure how this project is to be reliably carried out without knowing what wizards could have invented for themselves - or, indeed, how far back the separation between the two societies goes historically. I'll give you the train, certainly, but on the other hand:
They celebrate Christmas.
Early Christianity may have existed before Muggle and wizard societies separated. It may have had both wizard and Muggle worshippers (Rowling is silent on the matter of religion, but resurrection would be just as miraculous to wizards). For that matter, Jesus could have existed in the Potterverse, in which case odds of him being a wizard are extremely high.
IIRC, they use the Roman alphabet, or at least I don't remember British muggle students having to learn a different alphabet.
The Muggle and wizard communities are tightly bound enough to maintain the same language (they share the same geographical territory, and intermarriage is not uncommon). Assuming that, at some point in the past, wizardry emerged from a Muggle population, there's no reason why the two should not share the same linguistic evolution.
Their spells show an influence from Latin.
Which suggests the existence of Roman wizards, supporting the above point.
Hogwarts resembles a British public school.
Fair point. Although I struggle to come up with a mechanism by which nearly-modern Muggle teaching practices should come to be adopted by a school founded nearly a millennium earlier by wizarding purebloods, and maintained in a highly conservative fashion. If anything, one might speculate that British public schools are influenced by Hogwarts.
They speak English, even if words relating to technology and science are absent.
See above.
They use a train.
No contest. Ditto the printing press. I think our best bet may be to look at technologies which wizards would not have developed on their own (e.g. in that no other standard wizarding form of transport we know remotely resembles a train, or something which could evolve into a train). But that's a much more limited list.
Early Christianity may have existed before Muggle and wizard societies separated. It may have had both wizard and Muggle worshippers (Rowling is silent on the matter of religion, but resurrection would be just as miraculous to wizards). For that matter, Jesus could have existed in the Potterverse, in which case odds of him being a wizard are extremely high.
Early Christians did not have a tradition regarding a fat, bearded man commemorating the birth of their savior by giving gifts to good children.
The next discussion thread is here.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
