  Outside of specifically judicial contexts, questions about coercion may arise, either with respect to shaping public policy, or for the sake of measuring social progress. For instance, we may want to know whether and under what circumstances workers are coerced into working, either in particular jobs, or in general. It may also be of interest to know whether sexual harassment in workplaces or schools is coercive, for purposes of justifying a legal response to it. Those who design medical and other human-subject-based experiments need to be able to determine whether their subjects participate freely or under coercion. More generally, market economic transactions are thought to add to overall welfare (economic efficiency), but only if they are performed freely, which includes their not being coerced. The possibility of relying on ballots, survey data and other communications will also depend on whether such responses are given free from coercion.
