"Interacting minds: The quantitative limits of collaboration"
"Most experimental studies on social decision making involve individuals interacting with agents that are simulated or hidden behind a computer screen. In addition, competition over resources tends to lie at the heart of these interactions. While providing interesting findings, these studies do not address an important aspect of social interaction: many of our everyday interactions are collaborative rather than competitive. I will outline an experimental paradigm for shifting from isolated individuals competing over resources to individuals interacting towards a common goal. I will apply signal detection theory to collective decision making in a simple perceptual task to evaluate the efficacy of collaboration and in turn to delineate some of the cognitive and biological limitations on collaboration. I will also make inferences about the information content of the interaction that takes place en route to arriving at a collective decision."
