Standardized Regression Coefficients for the collective intelligence factor c as found in Woolley et al.'s (2010) two original studies. c and average (maximum) member intelligence  scores are regressed on the criterion tasks.

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.

Woolley,Chabris,彭特兰,Hashmi,& Malone (2010) ,一个完善的分类组任务。任务从复杂的四个象限中选择,包括视觉谜题、头脑风暴、做出集体道德判断以及在有限的资源上进行谈判。对这些任务的结果进行因子分析。两项研究都表明支持一般集体智力因素 c,在群体绩效的潜在差异中,最初的特征值占方差的43% (研究2中为44%) ,而下一个因素只占18% (20%)。这符合研究中通常发现的范围,一般个人智力因素 g 通常占认知测试中个人表现差异的40% 至50% 。

伍利,察布里斯,彭特兰,哈什米(2010)是集体智能这一科学概念的创始人,他们在192个群体的研究中发现了集体智能的单一统计因子,这192个群体的成员均是从公众中随机招募的。研究中,每个组群都是基于麦格拉思任务环McGrath Task Circumplex(一种完善的小组任务分类法)进行合作。这些任务是从四个象限中选择的,包括视觉难题,头脑风暴,集体道德判断以及就有限的资源进行谈判。将这些任务中的结果用于因子分析。两项研究均显示出了综合集群智力因子c的特征,并且根据群体的不同表现出了一定的差异,其初始特征值约占这些差异的43%(研究2中为44%),而另一个因子仅占18%(20%)。该数据与综合个体智力因子g的范围相符,通常在认知测验中占个体间性能差异的40%至50%。

Afterwards, a more complex criterion task was absolved by each group measuring whether the extracted ''c'' factor had predictive power for performance outside the original task batteries. Criterion tasks were playing [[Draughts|checkers (draughts)]] against a standardized computer in the first and a complex architectural design task in the second study. In a [[regression analysis]] using both individual intelligence of group members and ''c'' to predict performance on the criterion tasks, ''c'' had a significant effect, but average and maximum individual intelligence had not. While average (r=0.15, P=0.04) and maximum intelligence (r=0.19, P=0.008) of individual group members were moderately correlated with ''c'', ''c'' was still a much better predictor of the criterion tasks. According to Woolley et al., this supports the existence of a collective intelligence factor ''c,'' because it demonstrates an effect over and beyond group members' individual intelligence and thus that ''c'' is more than just the aggregation of the individual IQs or the influence of the group member with the highest IQ.<ref name=":0" />

然后,一个更复杂的标准任务被免除,每组测量提取的 c 因子是否对原任务电池之外的性能有预测能力。标准任务是下棋(跳棋)对标准计算机在第一个和复杂的建筑设计任务在第二个研究。在同时使用小组成员的个人智力和 c 来预测标准任务的表现的回归分析中,c 有显著的效果,但是平均和最大的个人智力没有。各组成员的平均智力(r0.15,p0.04)和最高智力(r0.19,p0.008)与 c 有中度相关,但 c 仍是标准任务的较好预测因子。根据 Woolley 等人的研究,这支持了集体智力因素 c 的存在,因为它证明了一种超越团队成员个人智力的影响,因此 c 不仅仅是个人智商的集合或者智商最高的团队成员的影响。

后来每个小组进行测试,验证提取c因子是否具有预测原始任务以外的能力,进而解决了更为复杂的判据任务。在第一个研究中,判据任务是在标准计算机上玩跳棋(国际跳棋),在第二个研究中则是复杂的建筑设计任务。在使用组员个人智力和c因子来预测判据任务执行情况的回归分析中,c具有显著作用,而平均和最大的个人智力则没有。虽然单个组成员的平均智力(r = 0.15,P = 0.04)和最高智力(r = 0.19,P = 0.008)与c有中等程度的相关性,但是c仍然是判据任务更好的预测指标。根据伍利等人的说法,该结果支持了集群智力因子c的存在,因为它证明了超出小组成员个人智力外的影响,因此c不仅仅是个人智商的累加,或单纯受到智商最高组员的影响。

Engel et al.<ref name=":4" /> (2014) replicated Woolley et al.'s findings applying an accelerated battery of tasks with a first factor in the factor analysis explaining 49% of the between-group variance in performance with the following factors explaining less than half of this amount.

恩格尔等人的研究(2014)在重复了伍利组员之前的研究发现,将加速任务组合与因子分析中的第一因素结合在一起,可以解释组间表现差异的49%,而其他因素解释占该比例一半以下。此外,他们在仅通过文本进行在线交流的小组中发现了相似的结果,并证实了女性比例和社会敏感性在两种情况下引起集体智能的作用。他们还模仿伍利小组使用RME来衡量社会敏感度,为了衡测试者感受他人眼中心理状态的能力。但是,在线合作参与者根本不认识也不见面。作者得出的结论是,RME的分数必须与更广泛的社会推理能力相关,而不仅仅是从其他人的眼神表情中得出推论。
