In an analysis of the data of 300.000 players of an online game society, Michael Szell and Stefan Thurner found that women have more communication partners. They also reciprocate friendships, organize in clusters, take fewer risks than men and show a preference for stability in their networks. On the contrary, men try to talk most often with those who talk with many, reciprocate friendships with other males much less frequently, and respond quite quickly to female friendship initiatives. They also tend to have less cooperative links with other males, which indicates a more competitive approach.
