Group psychology refers to the psychological state after individuals gather into groups, which is manifested as the obvious herd psychology of individuals in groups. Le Pen calls it "the psychological law of the unity of group spirit". In this state, the conscious personality disappears, and the unconscious personality gains momentum, "he is no longer himself, he becomes a doll no longer dominated by his own will.". Group psychology is a psychological state formed by individuals gathering into groups, which is not a simple result. Its formation is affected by the basic characteristics of groups.
