Keta, I agree, somewhat. The ultimate use of personality profile traits should be allow you to filter for/out specific kinds of profiles you want. Such as, a story-driven person looking for a thief who will likely betray them at some point due to selfishness and greed, or finding a noble knight who would never hurt a fly. I think there's utility in being able to find such things, I just don't think we've found the right language to appropriately describe them.
Traits should be fairly simple and only have a few categories in them each. Ideally, they should be immediately self-evident, or as much as possible, and be something in which one person could not reasonably exist in multiple categories without something like magic. They should be atomic, composeable, easy enough to type or remember, and hopefully not controversial.
So, in the most ideal scenario, I'd be able to :
find female, criminal, selfish, evil profiles into theft
to get example one and
find male, noble, kind, selfless profiles into guarding
to get example two
