Review Detail of Notacatowner in Harry Potter and the Methods of Rationality

This is quite possible the best hp fanfiction ever written. The story has thought experiments, social problems, and quite possible the most rational (pun intended) world-building of all hp fanfics. The story employs the trope of a educated, smart mc. However, as opposed to making other characters dumber to make the mc seem smarter, the mc himself is extremely smart, and yet there are people in the world who are smarter even than him. Thankfully, with the power of ACTUAL SCIENCE and rational thinking, he manages to keep a slight advantage? over others. I cannot stress this enough. THIS. STORY. IS. GREAT.
