Who put forward the introspection method in the teacher recruitment examination? Mencius? Confucius?

Confucius said, "If you feel guilty after introspection, why worry and fear" (The Analects of Yan Yuan). This means that he is innocent of what he usually does, so he can reflect on himself and feel fearless. Structural psychology, the first school after psychology became an independent science, defined the research object of psychology as direct experience, and introspection became the basic method of psychological research.
