Hertwig and Ortmann suggest paying participants contingent upon performance in order to increase the thoroughness they devote to a decision task. We argue that monetary incentives can yield a number of unintended effects including distortions of the subjective representation of the task and impaired performance. Therefore, we conclude that performance-contingent payment should not be generally employed in judgment and decision research.
