Like many things this is culture bound (so don't expect these friendship paradigms to be universal) and greatly generalizes. Who is the sample? White middle class people with enough money to participate in fishing vacations and buy golf equipment?

Women and men have friendships of all varieties and types. Not all women want to talk to strangers in a bathroom. Yuck. Furthermore, men get together and share emotions in some groups. Women get together only to work on projects in other groups or participate in sports, etc.

You cannot boil people down this simply. There is not one set of men and one of women. However, writing about that is far less compelling or interesting. Researching everyone is impossible. I dislike these studies like this greatly.
