The passage around this formula
…that this special case almost never held over evolutionary history for fitness-relevant judgments: whenever exceeds , the right-hand side falls below one, and the cost-minimizing rule requires inferring H even when the raw likelihood ratio is unfavorable to it, which looks, from the classical vantage point, exactly like a bias. Haselton and Buss’s original 2000 paper tested a specific instance of this logic in cross-sex judgment: because a missed mating opportunity was plausibly costlier to male…
