Aiming to choose correctly or to choose wisely? The optimality-accuracy trade-off in decisions under uncertainty

Thomas Garcia and Sébastien Massoni ()

Working Papers from HAL

Abstract: When making a decision under uncertainty, individuals aim to achieve opti-mality. In general, an accurate decision is optimal. However, in real life situations asymmetric stakes induce an unusual divergence between optimality and accuracy. We highlight this optimality-accuracy trade-off and study its origins using two experiments on perceptual decision making. We use Signal Detection Theory as a normative benchmark. The first experiment confirms the existence of an optimality-accuracy trade-off with a leading role of accuracy. The second experiment explains this trade-off by the concern of people for being right. Abstract When making a decision under uncertainty, individuals aim to make the best
