The way I see it, actual arrogance is a character flaw, allowing yourself to become secure in your "knowledge" that you have something over other people which makes you unconditionally superior. I don't think there's much you can do to cure that except introspection. If you do not actually think of yourself as superior to others, you can accidentally appear arrogant by failing due diligence when communicating with other people, which in turn may be caused by lack of practice. Pay attention to what you say, and think of what you could have said to deliver your message better. Especially in writing it's important to imagine how the reader may react to your words, and consider the benefit of terseness over the possibility that you may be misunderstood or misinterpreted. Going over your phrasing once or twice is a good idea as well. Also keep in mind that whoever you're talking to can not know everything that you know, and that this is often not their own fault.
