Paternalism is action that limits a person's or group's liberty or autonomy against their will and is intended to promote their own good. It has been defended in a variety of contexts as a means of protecting individuals from significant harm, supporting long-term autonomy, or promoting moral or psychological well-being. Such justifications are commonly found in public health policy, legal theory, medical ethics, and behavioral economics, where limited intervention is viewed as compatible with or even supportive of personal agency.
