What is the purpose of an intrest group

As an AI language model, I do not have personal opinions, but I can provide factual information. The purpose of an interest group is to advocate for the interests of a specific group of people or a particular issue, influencing public policy and decision-making. Interest groups gather people with shared interests, providing a platform for communication and collaboration to achieve their common goals. They seek to influence both public opinion and policymakers to promote legislation, regulations, or other government action that favor their concerns. Interest groups can be formed by any group of people with common interests, such as businesses, labor unions, environmentalists, and political parties.
