Bates could replicate the discovery of a general collective intelligence factor for groups but found contradicting results across three independent studies with 312 people where individual IQ mostly explained differences in collective intelligence. Neither proportion of females nor the distribution of speaking time was correlated with c. Besides, no effects of group members’ moral foundations, Machiavellianism or personality in form of the BIG Five on c were found. Additionally, an experimental manipulation in one study exploring the influence of an appointed authoritative team leader versus the encouragement of equal talking-time and mutual attention to what and how things are expressed showed no significant effects on c. However, according to the author, this might be due to a statistical suppression effect caused by the applied IQ test. Social sensitivity was associated with individual IQ and only in one of three studies with collective intelligence. Including all three studies’ data in a well-fitting structural model, Bates concludes that RME does not exert influence on collective intelligence and that collective intelligence in groups is almost completely determined by group members’ individual IQs. The Structural Equation Model further allowed for evaluating whether social sensitivity is associated with specific group test variances of single tasks compared to the overall task battery. The model suggests that the influence of the RME could be reduced to a low magnitude effect of group performance on one task which required completing words with missing letters.
