+# Conditional decision market selection bias is mitigatable through decision-maker market participation, timing transparency, and low-rate random rejection without requiring structural redesign
+
+Hanson identifies that selection bias in decision markets arises specifically 'when the decision is made using different info than the market prices' — when decision-makers possess private information not reflected in market prices at decision time. He proposes three practical mitigations: (1) Decision-makers trade in the conditional markets themselves, revealing their private information through their bets and reducing information asymmetry. (2) Clear decision timing signals allow markets to know exactly when and how decisions will be made, reducing anticipatory pricing distortions. (3) Approximately 5% random rejection of proposals that would otherwise pass creates a randomization mechanism that reduces selection correlation without requiring the 50%+ randomization that would make the system impractical. This framework predates Rasmont's January 2026 'Futarchy is Parasitic' critique by one month and provides the strongest existing rebuttal to the structural bias concern. Critically, Hanson's mitigations work through information revelation mechanisms rather than manipulation-resistance — they assume the problem is solvable through better information flow, not just arbitrage opportunities. However, Hanson does not address the case where the objective function is endogenous to the market (MetaDAO's coin-price objective), which is central to Rasmont's critique.
