Complexity means it requires additional things to happen even if you had no evidence.
For example, a more complex hypothesis than "Bob is a human" is "Bob is a human who lives at 123 Fake St."
Voldemort being called the dark lord is evidence, and learning about new evidence does not itself make a hypothesis more or less complex. It's just evidence.
You seem to be saying "A is more complex than B means 'if A then B' ", which is not true. The commonly used term for this is "strength". "Bob is human who lives at 123 Fake St." is strictly stronger than "Bob is human".
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 96. The previous thread is at almost 300 comments.
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, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, .
