Blame Jen McCreight
I’ve been reading fanfiction for the first time in several years and it’s all Jen McCreight’s fault.
The premise for this fic is that Harry Potter is hyper-rational and it is, essentially, pointing out how logically flawed the Harry Potter books are. With love, obviously. It’s surprisingly enjoyable, so if you’re a skeptic and an HP fan, I recommend it. I’ve gotten to Chapter 19…
Now, for the first time, he was up against the prospect of a mystery that was threatening to be permanent. If Time didn’t work by acyclic causal networks then Harry didn’t understand what was meant by cause and effect; and if Harry didn’t understand causes and effects then he didn’t understand what sort of stuff reality might be made of instead; and it was entirely possible that his human mind never could understand, because his brain was made of old-fashioned linear-time neurons, and this had turned out to be an impoverished subset of reality.
