Quadratic Voting (QV) is a new way of allowing people to express their preferences. Unlike traditional voting systems, where voters simply vote yes/no or at best rank their choices, QV lets people speak louder on the issues most important to them and agree to compromise elsewhere. This improves information quality and protects minority interests while giving people more democratic freedom and discouraging polarization. The real breakthrough here is that people can influence issues in proportion to how much they know and care about them. And by gathering more nuanced perspectives on what really matters to people, even large and diverse groups can quickly find what everyone agrees on, consensual solutions with broad and strong support.
