The phenomenon describes individuals who benefit from a public good or service without contributing to its cost. In a political science context, particularly within the framework of Advanced Placement Government courses, this often refers to citizens who enjoy the advantages of interest group activity, such as lobbying for favorable policies, without actively participating in or financially supporting the group. For example, an individual might benefit from cleaner air resulting from environmental regulations advocated for by an environmental interest group, even if they are not a member of that group or have not contributed to its activities.
This poses a challenge to collective action. If enough individuals choose to benefit without contributing, the interest group may struggle to secure the resources necessary to effectively advocate for its goals. Historically, interest groups have employed various strategies to mitigate this issue, including offering selective benefits (benefits only available to members) and attempting to cultivate a sense of shared purpose and obligation among potential members. The prevalence of the problem influences the types of interest groups that form and the tactics they employ.
