Memes-Arrogance : 12 items
I don't really think think that knowledge makes people humble, and arrogance makes people ignorant: that stuff comes from deeper down. But a little knowledge gives people a bravado that more knowledgable people often don't have (called the Dunning-Kruger effect). And arrogance makes people not question their righteousness. So there's a correlation, even if it's not causal.
