I think you're severely misunderstanding what it is they did in this experiment. The overall emphasis was not at all on the gender of the participants. As the article took pains to point out, they formed the groups based on a variety of intelligence scores - not gender.

Initially, they discovered that the most significant factors were "the high average social sensitivity of group members, a high rate of sharing who gets to communicate, and more females". Then they controlled for the number of females in each group, and discovered that the number of females actually didn't matter so much - the women in the study were just more likely (than the men) to have high social sensitivity, so a team with many women would be more likely to do well. But a team consisting of all men would also do very well, as long as you made sure to pick men with high social sensitivity.
