{{Main|Collective intelligence}}

A recent scientific understanding of collective intelligence, defined as a group's general ability to perform a wide range of tasks,<ref>{{Cite journal|last1=Woolley|first1=Anita Williams|last2=Chabris|first2=Christopher F.|last3=Pentland|first3=Alex|last4=Hashmi|first4=Nada|last5=Malone|first5=Thomas W.|s2cid=74579|date=2010-10-29|title=Evidence for a Collective Intelligence Factor in the Performance of Human Groups|journal=Science|volume=330|issue=6004|pages=686–688|doi=10.1126/science.1193147|issn=0036-8075|pmid=20929725|bibcode=2010Sci...330..686W|doi-access=free}}</ref> expands the areas of human intelligence research applying similar methods and concepts to groups. Definition, operationalization and methods are similar to the psychometric approach of general individual intelligence where an individual's performance on a given set of cognitive tasks is used to measure intelligence indicated by the [[G factor (psychometrics)|general intelligence factor ''g'']] extracted via factor analysis.<ref>{{Cite journal|last=Spearman, C.E.|date=1904|title="General intelligence," objectively determined and measured|journal=American Journal of Psychology |volume=15 |issue= 2|pages= 201–293|doi=10.2307/1412107|jstor=1412107}}</ref> In the same vein, collective intelligence research aims to discover a ''c'' factor' explaining between-group differences in performance as well as structural and group compositional causes for it.<ref>{{Cite journal|last1=Woolley|first1=Anita Williams|last2=Aggarwal|first2=Ishani|last3=Malone|first3=Thomas W.|date=2015-12-01|title=Collective Intelligence and Group Performance|journal=Current Directions in Psychological Science|volume=24|issue=6|pages=420–424|doi=10.1177/0963721415599543|s2cid=146673541|issn=0963-7214}}</ref>
