A recent paper [Woolley, Chabris, Pentland, Hashmi, & Malone. (2010). "Evidence for a collective intelligence factor in the performance of human groups." "Science", 330, 686-688] presents evidence for the existence of a general collective intelligence factor, "c," which may undergird performance on a variety of group tasks. This factor appears to be only modestly correlated with the average and maximum intelligence of group members whilst being more strongly correlated with the average social sensitivity of group members, a tendency for several members to contribute to group conversations rather than a small number dominating the discussions, and the proportion of females in the group. An alternative hypothesis, not considered by the authors, is that the General Factor of Personality (GFP) is able to account for the correlates of c observed, and that c may therefore be primarily a group level manifestation of the GFP, with a subordinate contribution from general intelligence. We maintain that a consideration of the GFP and its correlates as potential confounding variables would be of considerable benefit to future research into collective intelligence.
