Delphi Pythia

Delphi Pythia is a powerful deliberation platform designed to uncover and measure which arguments truly change minds within a public discourse. Key features include: • Real respondents provide all arguments • System maps emerging debate in real-time • Randomized experiments verify argument effectiveness • Two-wave process: discover, then verify • Anonymous argument evaluation This platform moves beyond simple polls or focus groups by offering a computational mini-public environment. In the first wave, participants contribute arguments in their own words, with the system clustering these arguments dynamically. An adaptive selector ensures every argument receives consideration, allowing the platform to identify arguments rated as persuasive by participants. The second wave then takes this frozen argument map and employs a randomized experimental design to measure which arguments actually shift positions, providing a direct measurement of influence rather than inferring it from ratings. Delphi Pythia employs sophisticated statistical methods, including reshuffling real data thousands of times for significance testing, and offers uncertainty-aware ranking. This approach provides a robust analysis of public opinion formation on contested questions. It's ideal for policymakers, researchers, and organizations seeking a deeper understanding of public sentiment and the true impact of different viewpoints, exemplified by its live demo on governing emerging technologies.
