Coercion (/ - /,) is compelling a party to act in an involuntary manner by use of threats, including threats of force. It involves a set of forceful actions which violate the free will of an individual in order to induce a desired response. These actions may include extortion, blackmail, or even torture and sexual assault. For example, a bully may demand lunch money from a student where refusal results in the student getting beaten.
Coercion can be used as leverage to force the victim to act in a way contrary to their own interests. Coercion can involve not only the infliction of bodily harm, but also psychological abuse (the latter intended to enhance the perceived credibility of the threat). The threat of further harm may also lead to the acquiescence of the person being coerced.
The concepts of coercion and persuasion are similar, but various factors distinguish the two. These include the intent, the willingness to cause harm, the result of the interaction, and the options available to the coerced party.: 126
John Rawls, Thomas Nagel, Ronald Dworkin, and other political authors argue that the state is coercive.: 28 Max Weber defined a state as "a community which has a monopoly on the legitimate use of force." Morris argues that the state can operate through incentives rather than coercion.: 42 In healthcare, informal coercion may be used to make a patient adhere to a doctor's treatment plan. Under certain circumstances, physical coercion is used to treat a patient involuntarily.
