I hate that being in the terra ignota fandom means I can’t good faith look down at the hogwarts houses thing anymore
Mapping schemes are mapping schemes, but quality does make a difference. The Hive system is pretty good at getting at something interesting; the Hogwarts houses as written are maximally terrible conceptual pigeonholes, they actively destroy information when you try to apply them. (Fandom has tried hard to redeem the system, but at the very least it’s an uphill climb.)
