Legitimacy is a psychological property of an authority, institution, or social arrangement that leads those connected to it to believe that it is appropriate, proper, and just. Because of legitimacy, people feel that they ought to defer to decisions and rules, following them voluntarily out of obligation rather than out of fear of punishment or anticipation of reward. Being legitimate is important to the success of authorities, institutions, and institutional arrangements since it is difficult to exert influence over others based solely upon the possession and use of power. Being able to gain voluntary acquiescence from most people, most of the time, due to their sense of obligation increases effectiveness during periods of scarcity, crisis, and conflict. The concept of legitimacy has a long history within social thought and social psychology, and it has emerged as increasingly important within recent research on the dynamics of political, legal, and social systems.

合法性和合法性的心理学观点。

合法性是权威，机构或社会安排的心理属性，它会使与之相关的人们相信它是适当，适当和公正的。由于合法性，人们认为他们应该遵从决定和规则，自愿遵循这些决定和规则是出于义务，而不是出于害怕受到惩罚或期望得到奖励的恐惧。合法化对于当局，机构和制度安排的成功至关重要，因为很难仅凭拥有和使用权力就对他人施加影响。由于他们的责任感，在大多数时间里，大多数人能够获得自愿默许，从而在稀缺，危机和冲突时期提高了工作效率。合法性的概念在社会思想和社会心理学中有着悠久的历史，
