Authoritarianism is a political system or philosophy in which individuals are subordinated to the state or organizational authorities that are perceived to be infallible, and where such authority has the right to exercise power over citizens without restriction or oversight. In an authoritarian regime, individual freedoms are often limited, dissent is suppressed, and the ruling authority maintains control through force, coercion, or propaganda.

In a medical context, authoritarianism can refer to a type of doctor-patient relationship in which the physician holds all the power and makes decisions without considering the patient's preferences or values. This approach can lead to poor communication, decreased patient satisfaction, and worse health outcomes. Instead, a more collaborative and patient-centered approach is generally recommended, in which patients are actively involved in their own care and decision-making processes.
