Combining Human Knowledge
Michael Lee, Department of Cognitive Sciences, UC Irvine, School of Social Sciences,

Different people know different things, and good answers and predictions to challenging problems can often benefit from combining human knowledge. In a wide array of military, political, social and other domains, an effect known as the  'Wisdom of Crowds' has been demonstrated, in which the aggregate answer across a group of people is more accurate than the answer of any individual in the group.  In this talk, we explore the effectiveness of a number of ways of combining human knowledge. We are especially interested in research questions that extend standard Wisdom the Crowd analyses by using cognitive models of decision-making.  One question is how structured and multidimensional human knowledge should be combined. Another question is how experts can be identified among crowds. A final question is how human knowledge should be combined if only a few people, and not a crowd, are available.
