First, what is the definition of racism? Racism is the term or diction of being discriminative towards a specific ethnic group of any kind, also due to your so-called "Psychology" experiences; it seems highly relevant that they are come across lessons concerning the human's thought process and many others factions related to affecting the human mind such as cultural properties, past experiences, etc. It is always generalized that the human mind is however limited, judgment is always second nature. Of course, this is purely obvious- and yes, racism is a problematic occurrence as you stated, but- it does not mean there is a possible miracle solution to easing human relations.
