Finally, teams with more women outperformed teams with more men. Indeed, it appeared that it was not "diversity" (having equal numbers of men and women) that mattered for the team's intelligence, but simply having more women. This last effect, however, was partially explained by the fact that women, on average, were better at "mindreading" than men.
This explains why it seems that the larger the group of men, the shittier they are.
Meanwhile groups of women actually accomplish good things. I think the reasonable conclusion is that we should leave men out of all group decisions. Male members of congress can go ahead and resign immediately, for the good of the nation.
