Actually, here's one that is somewhat of a detriment - when making plans or giving instructions, I leave out any information that wouldn't affect what they need to do/choose, whereas people usually expect a "complete" description so they can build an image in their head. "Why would you want to know that? It won't affect your decision either way."
