It's interesting because it's undoubtedly true that bias and prejudice affect one's interactions with the world. At the same time, it's true to that this can contribute to a vicious cycle via self-fulfilling prophecy.

I would say that sometimes you have to make a distinction between truths about the world and beliefs that can be helpful to you personally; sometimes these are in contradiction with each other, so you may find that you have to prefer to fiction to the truth in order to achieve better results.

This seems to be very common and accepted wisdom in the world of sports: a weaker opponent going against a stronger opponent may have virtually no chance of success, but they can marginally improve those chances via "belief."
