Finally, and most surprisingly to us, we found that the collective intelligence of the group was significantly correlated with the percentage of women in the group. More women were correlated with a more intelligent group. Interestingly, this last result is not just a diversity result. It’s not just saying that you need groups with some men and some women. It looks like that it’s a more or less linear trend. That is, more women are better all the way up to all women. It is also important to realize that this gender effect is largely statistically mediated by the social perceptiveness effect. In other words, it was known before we did our work that women on average scored higher on this measure of social perceptiveness than men. This is the interpretation I personally prefer: it may be that what’s needed to have an intelligent group is just to have a bunch of people in the group who are high on this social perceptiveness measure, whether those people are men or women. In any case, we think it’s an interesting finding, one that we hope to understand better and one that already has some very intriguing implications for how we create groups in many cases in the real world.
