Abstract
We propose the use of discussion structures as tools for analyzing policy debates in a way that enables
the increased participation of lay stakeholders. Discussion structures are argumentation-theoretical tools
that can be employed to tackle three barriers that separate lay stakeholders from policy debates: difficulty,
magnitude, and complexity. We exemplify the use of these tools on a debate in research policy on the
question of responsibility. By making use of discussion structures, we focus on the argumentative moves
performed by the parties involved in this debate. We conclude by discussing advantages and limitations of
discussion structures and we trace several opportunities for further research on these instruments
