Executive Summary

Designing social media platforms to foster healthy democratic discourse is a critical challenge driven by the limitations of today's engagement-focused, ad-revenue model. To spark cross-disciplinary innovation beyond these profit-driven incentives, this white paper introduces a set of actionable "mechanisms" designed to reduce harms like misinformation and political polarization. Ultimately, this paper serves as both a entry point for public and expert debate and a proposal of designs aimed at rebuilding a digital public sphere that enhances collective intelligence.
