That's not entirely true, though. By being aware of ones biases, one can attempt to overcome them, or at least modulate one's thoughts and actions to take into account the fact that they are there. Take Cognitive Behavioral Therapy, for instance, in which patients seek to recognize their own biased ways of thinking in order to lessen their biases and dissociate these thoughts from emotion and action. The same principles applies to reflecting upon one's thought processes (metacognition) in general, though perhaps to a lesser degree. While becoming aware of one's biases by oneself is difficult, one can understand ones own prejudices - certainly those that we know that more or less everybody has a propensity towards. In my opinion, these biases and irrational thoughts are not weaknesses inherent in all of us. I think they are rather something we all have potential for, but which is expressed differently in each of us.
