What roles can science and scientific experts adopt in policymaking? One way of examining this is through the Advocacy Coalition Framework (Sabatier and Jenkins-Smith 1993). This framework highlights that policymaking and the negotiations regarding a political issue—such as reform of the health system, or the introduction of an energy tax on fossil fuels—is dominated by advocacy coalitions in opposition. Advocacy coalitions are groups of actors sharing the same opinion about how a policy should be designed and implemented. Each coalition has its own beliefs and ideologies and each wants to see its preferences translated into policies.
