Fuck it, I'm good to Gonch this out.
I forget, did we ever actually learn who the killer was in Murder at Wizard University? I remember it kept coming up through the first book as a kind of motif for how this new world wasn't necessarily as safe and clean as Tommy expected, but I think that whole business with the Thoughtknot ended up overshadowing it before the actual killer was revealed. Like, I get it thematically or whatever but it just stuck in my head as a loose thread and has bugged me for years.
Ironically I think it's also been discussed most frequently within Rationalist circles that these types of intelligence aren't often correlated. I'm not going to chase down links right now because doing an SSC archive exploration requires more mental fortitude than I currently possess, but I distinctly remember that a recurring theme was "if nerds are so smart why don't they rule the world?" In my less cynical days I had assumed that his confusion on this point was largely rhetorical, intended to illustrate some part of whatever point was buried in the beigeness. Now it seems like I was falling victim to the ability to project whatever tangentially-related thesis you want onto the essay and find supporting arguments because of how badly it's written.
