In their recent article Self-interest within the Advocacy Coalition Framework: how material beliefs affect change in German munitions policy, authors Alexander Pechmann and Jochen Hinkel, examine how self-interest shapes coalition dynamics and policy change. Using the Advocacy Coalition Framework (ACF), the authors introduce the concept of material beliefs to better explain how actors motivated by self-interest interact with those driven by broader societal goals.  

The article addresses a longstanding critique of the ACF. While the framework recognises that policy actors may be motivated by both societal goals and self-interest, empirical studies often focus primarily on purposive beliefs—those linked to wider societal objectives such as environmental protection or public health. Pechmann and Hinkel argue that this emphasis risks overlooking how actors’ material interests—such as financial gain or political influence—shape coalition behaviour and policy outcomes. 

To address this gap, the authors conceptualise material beliefs as beliefs oriented towards short-term benefits for the actor or their affiliated group, while purposive beliefs concern longer-term goals that benefit society more broadly. By integrating material beliefs directly into the ACF belief hierarchy, the article offers a clearer framework for analysing how self-interest operates within policy subsystems.
