本研究报告的几个荟萃分析的结果，研究团队内的认知能力（最高成员得分，最低成员得分，平均得分，标准差的分数）和团队绩效的四个操作定义之间的关系。与水平相关的三个指数产生了适度和积极的样本加权估计的人口关系（.21至.29），但抽样误差，未能占足够的变化，以排除调节变量。相反，与色散相关的指数（即，成员得分的标准差）与团队绩效基本无关（-0.03），抽样误差为研究间观察到的变化提供了合理的解释。亚组分析显示，平均认知能力是一个更好的预测团队的表现在实验室设置（.37）比内场设置（.14）。研究的局限性，实际意义，和未来的研究方向进行了讨论。
This study reports the results of several meta-analyses examining the relationship between four operational definitions of cognitive ability within teams (highest member score, lowest member score, mean score, standard deviation of scores) and team performance. The three indices associated with level yielded moderate and positive sample-weighted estimates of the population relationship (.21 to .29), but sampling error, failed to account for enough variation to rule out moderator variables. In contrast, the index associated with dispersion (i.e., standard deviation of member scores) was essentially unrelated to team performance (-.03), and sampling error provided a plausible explanation, for the observed variation across studies. A subgroup analysis revealed that mean cognitive ability was a much better predictor of team performance in laboratory settings (.37) than infield settings (.14). Study limitations, practical implications, and future research directions are discussed.
