New angular mean rule balances diverse voter preferences in decision-making

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a new method for collective decision-making called the "angular mean" to address proportional sequential decisions. This approach aims to balance diverse voter preferences in ranking items, unlike the traditional arithmetic mean which can be majoritarian. The angular mean surprisingly satisfies long-run individual proportionality, ensuring fairness over time. While exact per-batch proportionality is unattainable with fixed linear rules, the angular mean significantly improves fairness in situations with high disagreement among voters. AI

IMPACT Introduces a novel method for balancing diverse preferences in sequential decision-making, potentially improving fairness in AI systems that rely on collective input.

    The End Justifies the Mean: A Linear Ranking Rule for Proportional Sequential Decisions

    AI alignment and participatory design motivate a new democratic design problem: how to collectively choose a decision rule to use repeatedly. We study this problem for linear ranking rules, which repeatedly rank items $x_j$ within batches $X=(x_1,\dots,x_m)\in(\mathbb{R}^d)^m$, w…
