Social cohesiveness, group satisfaction, and psychological safety are not predictors of collective intelligence, suggesting that CI is a component that arises separately from the quality of group relationships.

Behaviors that are not predictors of Groups High in CI

The way group members interact with each other can influence a group's collective intelligence. An equal level of communication and participation in the group by each member was shown to be a strong predictor of high collective intelligence. In groups in which a small percentage of members dominate both communication and participation were seen to be generally less collectively intelligent. 
There is some research that collective intelligence is not as related to the quality of group relations, like social cohesiveness or psychological safety, as previous research has suggested. 

Group Interactions influence on Collective Intelligence 

Top-down processes involve group structures, norms, and routines that guide collective behavior.

Scholars are interested in how collective intelligence can influence a group's performance. They are also interested in whether collective intelligence can be used to predict group performance.

Collective Intelligence and Group Performance

In this study, collective intelligence is defined as a specific group’s ability to perform well across a range of different tasks. Overall cognitive diversity, group interaction, communication, and individual skills, like social perceptiveness, can be seen to influence Collective Intelligence. The collective intelligence of a group is a significant predictor of its performance on these tasks, while the average individual intelligence of group members is, surprisingly, not. Overall, collective intelligence is thought to emerge from both bottom-up and top-down processes. These processes can either be beneficial or detrimental to group performance.  

Collective Intelligence's predictability on Group Performance

Bottom-up processes are the sum of individual group member characteristics that contribute to collaboration.
