Okay, I had to start this one. They seem to sort the kiddies at Hogwarts into houses based on singular personality traits, so I was curious to see if it would be possible to allocate a house for every type. And whether that would end up with terribly lopsided numbers.
So, here we go:
Gryffindor: 'brave', 'daring', 'chivalrous' (disregard for the rules?)
ENFP, ENFJ, ESTP, ISTP
Hufflepuff: 'just', 'loyal', 'hard-working'
INFP, INFJ, ISTJ, ESFJ, ISFJ
Ravenclaw: 'wise', 'clever', 'intelligent'
Slytherin: 'cunning', 'ambitious', 'sharp'
ENTJ, INTJ, ESTJ, ESFP, ISFP
Rearrange at will!
