Forest plot: The c-factor and Criterion Tasks. Note. Results are displayed for a random effects model pertaining to correlations between the c-factor and various criterion tasks. The c-factor scores are operationalized using factor/principal component regression weights. Most studies did not report which method was used to calculate these weights (e.g., Bartlett method). All studies included in this analysis, except for Rowe (2019), were undertaken by Woolley and colleagues and therefore employed procedures and measures described in Woolley et al. (2010) and/or Engel et al. ( 2014ab). Criterion tasks were different across all studies. Box sizes are relative to sample weights. *Two effects (team learning and team synergy) by Woolley and Aggarwal (under review) from one unique sample (n = 59) were included in this meta-analysis, leading to a total N = 916 when the sample was added on the basis of each unique effect or a total N = 857 when the sample was added on the basis of each unique group
