Is it possible to have an opinion on something and not have a bias in any way? Take the Israeli-Palestinian conflict for example. If I were to research both sides extensively, learning every single fact I could from every single possible source, then find that one side was clearly in the wrong most of the time. Could I say "Israel is in the wrong more than the Palestinians" without having a Palestinian bias? And furthermore, what does the word "bias" entail? What is its meaning?
