**Claim.** Unanimity is a cascade-consistent quantity: unusually frequent unanimous verdicts are consistent with validators discounting private information in favor of perceived group consensus, but they do not uniquely identify the Banerjee and Bikhchandani-Hirshleifer-Welch mechanism, with Holmström’s free-riding equilibrium supplying the complementary reading that leaning on the apparent consensus is what costly evaluation effort converges to when its product is shared.
