If you have read Jurassic Park, then you will know that geneticists are the most arrogant scientists. (Mathematicians are always justifiably correct, so that doesn't count as actual arrogance.) Paleontologists are the humble saints of the scientific community.

In reality? Anyone has the potential for it. Talk to an artist some time. Say something controversial, like, "while Renaissance art may be passable in terms of technical ability, it wasn't until the Impressionists that composition became anything more than laughable." You will see.

At my school, business students think they run the show. A big streak of arrogance seems to be a prerequisite for entering that programme.

I've yet to meet any real scientist whom I considered to be arrogant in terms of refusing to talk about his research. Ask a scientist about the work in his field and it is generally impossible to shut him up. That's my experience, anyway.
