 MaxMin-RLHF provides a constructive implementation of pluralistic alignment through mixture-of-rewards and egalitarian optimization. Rather than converging preferences, it learns separate reward models for each subpopulation and optimizes for the worst-off group (Sen's Egalitarian principle). At Tulu2-7B scale, this achieved 56.67% win rate across both majority and minority groups, compared to single-reward's 70.4%/42% split. The mechanism accommodates irreducible diversity by maintaining separate reward functions rather than forcing convergence.

+EM-DPO implements this through ensemble architecture: discovers K latent preference types, trains K specialized models, and deploys them simultaneously with egalitarian aggregation. Demonstrates that pluralistic alignment is technically feasible without requiring demographic labels or manual preference specification.

 RLCF makes the social choice mechanism explicit through the bridging algorithm (matrix factorization with intercept scores). Unlike standard RLHF which aggregates preferences opaquely through reward model training, RLCF's use of intercepts as the training signal is a deliberate choice to optimize for cross-partisan agreement—a specific social welfare function.

+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.

 Cloak raised only $1,455 against a $300,000 target (0.5% of target), entering refunding status. This represents a near-total failure of market validation, contrasting sharply with the 15x oversubscription pattern. The project had shipped product (live mainnet beta with Oro integration), had credible team (repeat builders, Superteam contributors), and addressed a real problem (MEV extraction on DCA orders). Despite these fundamentals, the futarchy-governed raise failed to attract capital, suggesting that product-market fit and team credibility are insufficient without pre-existing community or distribution.
