  More generally, Nozick's analysis emphasizes the alteration in the coercee's choice of actions which results from the way the coercer's proposal affects her reasons for acting. While this is certainly a plausible approach for distinguishing coerced from uncoerced acts, it puts the focus on how the coercee perceives her situation; it is only via this reflection that it takes into account how the coercer is able to create this perception. That is, it leaves the standard sorts of means (force, violence, perhaps even economic deprivation) that coercers use out of the account, and instead treats all kinds of alterations to the coercee's costs and benefits to acting as possible indications of coercion. While this more ecumenical approach to coercion may succeed in encompassing ways of coercing that the traditional theories would leave out, it creates a difficult challenge for the theory to distinguish coercive from non-coercive proposals. It is not surprising, therefore, that these are the issues that have been the focus of most subsequent theorizing on the subject.
