How can protecting self-esteem motivate a person to lie?

Protecting self-esteem is identified by psychologists as a primary motive for lying. When individuals feel their sense of self-worth is threatened, they may engage in deceptive communication to manage how they are perceived by others or to shield themselves from negative self-evaluation.1

By presenting a false version of reality, a person may attempt to maintain a positive self-image or avoid the discomfort associated with perceived failures, social disapproval, or personal shortcomings. While lying is often used to manipulate outcomes or avoid conflict, its role in preserving self-esteem highlights how deception can function as a psychological defense mechanism.1

It is important to recognize that, from an ethical standpoint, lying involves treating others as a means to an end rather than as individuals with their own rational capacity. Philosophers such as Immanuel Kant argued that lying is an assault on morality because it undermines the autonomy of others. Regardless of the motivation to protect one's self-esteem, choosing honesty remains a fundamental ethical principle, as it respects the truth and the integrity of human interaction.1
