What characterizes a pressure group?

A pressure group is primarily characterized by its focus on a singular issue to influence policy. This means that pressure groups often center their efforts on specific topics, such as environmental protection, animal rights, or health care reform. By concentrating their resources and advocacy on one particular issue, they aim to effectively mobilize support and persuade policymakers to adopt their desired changes. This targeted approach allows them to create a strong narrative and establish themselves as experts in that field, making their campaigns more impactful.

While some pressure groups may indeed have no membership fees, represent a broad segment of society, or promote multiple agendas, these traits are not defining characteristics. The essence of a pressure group's function is its dedicated focus on influencing policy regarding a specific issue, which is what sets it apart from other types of organizations.
