In Stephen Covey's 7 habits he writes about truly effective people, describing them as having the humility to recognize their own limitations. Effective people value differences because they know that these different perceptions add to their own knowledge and understanding of situations. Covey writes that if two people have the same opinions then one of them is unnecessary. I agree with this statement. Oftentimes the best conversations I have are with people who see things differently from me - and these are the people that I learn the most from.
