Polis

An open-source platform for large-scale opinion gathering and analysis that complements lottery-selected citizen assemblies by expanding participation and enhancing deliberative processes. Polis integrates with assemblies through six strategies: topic selection, topic framing, epistemic diversity in member selection, assembly self-understanding, distributed deliberation beyond physical constraints, and collaborative document review. The platform broadens public engagement beyond assembly membership, reveals consensus points, and strengthens legitimacy through broader input.
