I could imagine an argument that the lack of ground truth makes multiagent aggregation disproportionately difficult, but that argument wouldn’t run through different agents having different approximation-preferences. In general, I expect the sort of approximations relevant to this topic to be quite robustly universal, and specifically mostly information theoretic (think e.g. “distribution P approximates Q, quantified by a low KL divergence between the two”).
