In social life, human roles dominate our perception, our attention is often attracted by people's daily activities, and often lacks a deep understanding of people outside the role, so in some seemingly profound Cognition inevitably exists based on surface or subjective views. The point directly supported by this passage is:. ['In social life, people have to play various roles.', 'Our understanding in society is based on an understanding of various roles.', 'Lack of understanding of people outside of the role can lead to subjective or superficial knowledge.', 'Avoid the influence of roles in order to have a more objective and profound understanding of people in society.']
