Certain people with degrees don't realize they've not as "intelligent" as they think they are. They have intellect, but lack intuition. They were able to copy/past information from their studies and from what they hear from others (intellect), but didn't learn how to read in-between the lines, recognize patterns, or do their own thinking (intuition). No practicality, no common sense. They "appear" smart in small contexts, but are lacking in real-world practical situations.

I don't hate anyone for pursuing higher education, I just dislike the arrogance and condescending nature of people who think they are the smartest people in the world when all they did was a get specialized knowledge in one specific topic by copying/pasting information to their head temporarily. It's like walking around thinking you're smarter and better than everyone, but you're just walking around with half a brain (only intellect, but lacking intuition).
