Interest Group Theory states that public policy is dictated by:

Interest Group Theory posits that public policy is primarily influenced by a multitude of interest groups that compete for attention and influence in the legislative and regulatory processes. This theory underscores the idea that various organized groups represent specific interests, such as business, labor, the environment, or social causes, and these groups seek to sway policymakers to adopt regulations or legislation that align with their objectives.

The presence of numerous interest groups creates a dynamic landscape where various perspectives are considered, leading to a more pluralistic approach in policymaking. This competition and collaboration among diverse groups are what ultimately shape the policies enacted by the government. In this model, public policy is seen as a product of negotiation and compromise among these different stakeholders rather than being dictated solely by one entity like political parties, government agencies, or the general public alone.
