Abstract: Facing perceptual decisions with asymmetric stakes, individuals exhibit a conservative criterion placement. This bias prevents them from reaching the optimal decision process defined as the one which maximizes their expected payoffs. We propose in the present experimental study a non-invasive method to correct behaviors toward more optimality. We manipulate the information order between payoff information and perceptual evidence for three different incentive levels invariant regarding Signal Detection Theory predictions. Our results support the effectiveness of such manipulation: the decision strategy shifts toward optimality when payoff information is displayed last. The shift toward optimality is more pronounced for higher payoff contrasts. These results, which cannot be explained within the Signal Detection Theory framework, give new insights on the cognitive processes responsible for the conservative criterion placement
