MEASURING COLLECTIVE INTELLIGENCE

Psychologists have repeatedly shown that a single statistical factor—often called “general intelligence”— emerges from the correlations among people's performance on a wide variety of cognitive tasks.  But no one had systematically examined whether a similar kind of “collective intelligence” exists for groups of people. In this work, we have found converging evidence of a general collective intelligence factor that explains a group's performance on a wide variety of tasks.  This “c factor” is not strongly correlated with the average or maximum individual intelligence of group members, but it is correlated with the average social sensitivity of group members, the equality in distribution of conversational turn-taking, and the proportion of females in the group.

Our continuing work is investigating the factors that affect the collective intelligence of a group, such as its size, the electronic collaboration tools it uses, and the gender mix of its members.
