Coercive power (‘stick’) is about punishment for non-compliance and the use of physical force, intimidation or other threats (consequences of non-compliance, such as fines, disapproval) to make someone do something against their will or intent. In its ‘light’ form, it could manifest as the protection of a child from harm or stopping a speeding driver. In its ‘shadow’ form, it could be used in political oppression. It may be intrinsic, as a result of physical size or strength, or an extrinsic power such as a weapon or threat of withholding a reward (extrinsic, because both can be lost by the coercer, eg. disarming them of their weapon, which then shifts the balance of power).
