 Comprehensive February 2026 survey by An & Du documents that contemporary ML systems implement social choice mechanisms implicitly across RLHF, participatory budgeting, and liquid democracy applications, with 18 identified open problems spanning incentive guarantees and pluralistic preference aggregation.

+The trilemma formalizes why RLHF's implicit social choice is problematic: achieving epsilon-representativeness (epsilon <= 0.01) and delta-robustness (delta <= 0.001) simultaneously requires super-polynomial compute, making the 'strategic relaxation' of representativeness a practical necessity that RLHF implementations make without explicit acknowledgment.

 An & Du's survey reveals the mechanism behind single-reward failure: RLHF is doing social choice (preference aggregation) but treating it as an engineering detail rather than a normative design choice, which means the aggregation function is chosen implicitly and without examination of which fairness criteria it satisfies.

+
+The formal trilemma proof shows preference collapse is not just empirically observed but mathematically necessary: single-reward RLHF cannot capture multimodal preferences even in theory. The paper quantifies the practical gap: current systems use 10^3-10^4 samples from homogeneous pools while 10^7-10^8 samples are needed for global representation — a 3-4 order of magnitude shortfall.
