What term describes using threats or deceit to compel an individual into services?

The term that describes using threats or deceit to compel an individual into services is coercion. Coercion involves forcing someone to act in a certain way or to agree to something against their will through threats, intimidation, or misuse of authority. This is particularly relevant in the context of human trafficking, where individuals may be manipulated into situations of exploitation under duress.

Manipulation generally refers to influencing someone in a deceptive way, but it does not always involve threats. Conscription is the compulsory enlistment of people, typically for military service, which is not aligned with the context of compelling individuals into services through deceit or threats. Recruitment implies a voluntary process of getting individuals into jobs or services, which contrasts with the coercive tactics mentioned in the question. Thus, coercion is the most accurate term that captures the forceful and deceptive nature of such actions in human trafficking scenarios.
