One factor in collective intelligence is the average social perceptiveness of the group members, evaluated through the Reading the Mind in the Eyes test. In this assessment, participants analyzed images of people's eyes to deduce their mental states. Originally designed to measure autism, the test revealed variations in individuals' social intelligence even among neurotypical adults. Notably, groups with a higher percentage of members performing well on this social perceptiveness test tended to display greater collective intelligence than those with lower scores.
