When I was getting my undergrad one of professors gave me the best gem of advice regarding objectivity: Objectivity is impossible. Before anything else, grammar itself renders it impossible. I, being a subject, cannot become the object. I can view the object, but I will never be objective because the object in question is not me. If it were, it would become the subject, and thus we return to where we started. All we can do is be aware of our prejudices, and even that is difficult.
