The project of minimizing bias is in some ways structurally similar to consequentialist moral theories, and I suspect that enthusiasm for it positively correlates with sympathy for consequentialism (am I right?). There are certainly important differences between the two projects. Those who want to minimize bias rarely see this as an intrinsically valuable goal. And the goal of minimizing error is far more determinate than that of maximizing well-being or value. But some of the intuitive objections to such a project sound to me very similar to familiar objections to consequentialism.
