There's a difference between arrogance and justifiable pride in one's accomplishments. I want people who've put decades of work into a field I couldn't understand in twice the time to be proud of what they've done. They should be. I don't even find people saying, "You couldn't hope to understand it" or being annoyed that someone who's not studied as much as they informs them that they're wrong to be arrogant. I think it's perfectly reasonable in many cases. I couldn't hope to understand particle physics! I could study for decades, and my eyes would still glaze over at every equation. It just doesn't interest me, and I'm not good at it. Since I haven't done the studying, I probably don't know enough to correct them.

Certainly there are arrogant scientists, and I'm certain everyone who works in science can name at least a few. However, pride in one's accomplishments, as I say, is not arrogance unless it's taken to extremes.
