Experimental evidence for structured information-sharing networks reducing medical errors.

Collective intelligence posits that the judgment (in this case, diagnostic accuracy) of a group of individuals outperforms the judgment of a single individual. This study sought to determine if real-time information-sharing improved not only group diagnostic accuracy, but also diagnostic accuracy of the individuals within the group. Individual accuracy did improve, suggesting real-time information-sharing between physicians could improve diagnostic decision-making in practice, although additional research is required.
