Woolley, Chabris, Pentland, Hashmi, & Malone (2010), the originators of this scientific understanding of collective intelligence, found a single statistical factor for collective intelligence in their research across 192 groups with people randomly recruited from the public. In Woolley et al.'s two initial studies, groups worked together on different tasks from the [[The Circumplex Model of Group Tasks|McGrath Task Circumplex]], a well-established taxonomy of group tasks. Tasks were chosen from all four quadrants of the circumplex and included visual puzzles, brainstorming, making collective moral judgments, and negotiating over limited resources. The results in these tasks were taken to conduct a [[factor analysis]]. Both studies showed support for a general collective intelligence factor ''c'' underlying differences in group performance with an initial eigenvalue accounting for 43% (44% in study 2) of the variance, whereas the next factor accounted for only 18% (20%). That fits the range normally found in research regarding a [[G factor (psychometrics)|general individual intelligence factor ''g'']] typically accounting for 40% to 50% percent of between-individual performance differences on cognitive tests.
