Democratic Reflection and other contested collective intelligence tools aim to harness technology to enable people to build consensus even when they disagree. These tools use techniques like crowdsourcing and natural language processing to analyze online conversations, identify points of agreement, and generate visualizations to help people reflect on different perspectives. Trials of these tools showed they can improve critical thinking, challenge assumptions, and potentially bridge political and social divides. The tools are being used to facilitate collaboration and evidence-based discussions among groups addressing complex issues like public policy, education, and building peace in places affected by conflict.
