Philosophy, Psychology and Neuroscience

"Interacting minds: miracle or disaster? What could each one tell us?"

Are two heads better than one? My talk will address this question in the context of collective perceptual decision making -- akin to what to the referee and his linesmen do in every football match. I will explore a number of limit conditions in which the collective is unexpectedly good or disastrously bad. A number of computational models of the content of communication will also be presented to see which one predicts these limit conditions best. I am keen to discuss the ramifications of this approach with you in several directions: (1) communication medium, (2) objective reference (about decision accuracy), (3) cultural differences, (4) biological/evolutionary factors, (5) conscious metacognitive awareness.
