been thinking lately, we might have a bias towards fear because it's better to mistake a stick for a snake than the reverse, some people's genes go too far with this and get anxiety disorders. maybe we also have a bias toward detecting betrayal, reciprocity being a big thing for mammals. humans needed to constantly track who was allied with whom in order to predict their behavior. so maybe some people's genes go too far detecting betrayal and they end up paranoid.
