This would be explicitly against Yudkowsky's stated goals for the story,
The Rule of Rationalist Fiction states that rationality is not magic; being rational does not require magical potential or royal bloodlines or even amazing gadgets, and the principles of rationality work for understandable reasons. A rationalist!hero should excel by thinking - moreover, thinking in understandable patterns that readers can, in principle, adopt for themselves. As opposed to the hero just being a born “genius” who comes up with amazing gadgets through an opaque discovery process, or who flawlessly pulls off incredibly complicated gambits that would fail miserably if the reader tried something similar in real life.
All he has that we don't is more facts. (Which is often a hindrance; it was easier for us to figure out Lucius's blood debt, because we had less "memory" to search through.) If he could also exceed natural human cognitive constraints, this wouldn't be rationalist fiction.

Assuming that Harry's Dark Side is integral to a significant proportion of plays(assuming rather than noting because my memory is patchy and I don't remember if it was like this or if the dark side was more a background character than an oft-employed tool), perhaps we could infer from this that EY considers it to be an natural state of mind that also happens to flourish rarely enough that no character Harry will ever meet is likely to be able to correct his misperception of it. I'd then assume EY must have visited it himself to write it.
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 98. The previous thread is at nearly 500 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, 25, 26.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
