Abstract


Using laboratory experiments, we provide evidence on three factors influencing trader performance: fluid intelligence, cognitive reflection, and theory of mind. Fluid intelligence provides traders with computational skills necessary to conduct statistical inference. Cognitive reflection helps traders avoid behavioral biases and thereby extract signals from market orders and update their prior beliefs accordingly. Theory of mind describes the degree to which traders correctly assess the informational content of orders. We show that cognitive reflection and theory of mind are complementary because traders benefit from understanding signals’ quality only if they are capable of processing these signals.
