What is one characteristic of free riders within interest groups?

Free riders within interest groups are individuals who benefit from the group's efforts without actively contributing to its work or supporting its objectives. This phenomenon occurs because interest groups often provide collective goods—benefits that are available to all members regardless of whether they contributed to the group's efforts to secure those benefits. For instance, a public interest group advocating for environmental protection may achieve policy changes that benefit all members of the community; thus, even those who do not pay dues or engage in advocacy can enjoy cleaner air or protected parks.

By contrast, the other options highlight actions and commitments that are atypical of free riders. Paying dues to support a group signifies an active contribution, while actively advocating for the group's goals indicates engagement and participation. Additionally, leading the organization's initiatives implies a proactive role that is contrary to the concept of free riding, where individuals do not take on such responsibilities yet still reap the rewards.
