Harry Potter and the Methods of Rationality

This extensive fanfiction reimagines the Harry Potter universe through the lens of rationalist epistemology. Instead of being raised by his neglectful aunt, Harry is adopted by his aunt Petunia and her husband, a biochemist, and grows up in a household that prioritizes scientific method, logical consistency, and empirical evidence. When he eventually discovers the wizarding world, he does not accept its magical rules at face value; instead, he applies rigorous analytical thinking to understand, test, and ultimately subvert the systems of magic and society around him.
