Do you have a strong instinct or gut feeling or do you ever practice and play with your intuition, this physical feeling of knowledge that hasn't yet been processed by the brain? You like psychology, did you know the human brain can process more than the conscious brain can? When we see someone and create a judgement, we are seeing tons of details that are clues to us. Some clues are based in reality and some from media stereotypes, but more often than not, those clues and conclusion, made faster than the conscious mind can create, can be correct. That's just an extension of faith, it's this feeling, gut feeling on something larger, and an experience of some sort that changes body chemicals.
