It's almost like you need unaffiliated third parties to rank people on their good qualities.

"Are you humble?"

"Oh yes, definitely, I'm one of the most humble people I know"

"Are you a good person?"

"Oh yes, one of the best"

vs.

"How humble would you say your co-worker is?"

"Hmm, in my opinion probably average humility. I've never seen them do anything that made me think they were especially humble."

"Would you say your co-worker is a good person?"

"Hard to tell. They don't particularly stand out as being especially good."
