Whether we want to admit it or not, we all have our bias. The inclination to lean onto a particular side. It stems from our experiences and the environment that we are in. The danger happens when we close ourselves off from ideas and opinions of those that are not aligned with ours. It is important to listen to them without preconceived judgments. This will actually result in a more robust understanding of the situation thus allowing one to make better decisions. Also, when you seek opinions of people you disagree with, it helps you to cover the blind spots or areas that you perhaps did not initially give much thought to and besides gaining their respect in the process, you broaden your thinking thus enabling you to make a firmer stand.
