Coercions

Coercions refer to acts or processes that compel a person to act in a certain way through threats, force, or pressure. They rely on the perceived or actual possibility of harm, punishment, or deprivation, rather than voluntary agreement or persuasion alone.

In law and politics, coercion denotes the use of power to compel compliance. States may employ coercion through sanctions, surveillance, or force. Legal systems distinguish coercion from voluntary consent; contracts signed under coercion may be void or voidable due to duress.

In mathematics and computer science, coercion (or type coercion) is the automatic or explicit conversion of a value from one type to another to satisfy an operation. Implicit coercion can introduce errors or ambiguity, while explicit coercion makes the conversion intentional.

In linguistics, coercion is a semantic process where a word’s category is forced to fit a sentence’s predicate. For example, a noun may be interpreted as an action or event to make sense of a sentence containing a verb of action.

Ethical and social analyses treat coercion as limiting autonomy and voluntary choice. Coercive practices include threats, intimidation, or unequal bargaining power. Contemporary discussions emphasize consent, protective laws, and mechanisms to limit coercive influence in personal, professional, and political domains.

See also coercive power, duress, manipulation, and coercion in programming languages. The term has diverse usages across disciplines, united by the core idea of enforcing conformity through pressure rather than voluntary action.
