Are there real differences between the friendships between men and women, or is it most based on prejudices and stereotypes? To me one thing is clearly. Men do more physically and talk less. Women find talking just more important than sharing their hobbies. The emphasis is on friendship between women therefore more based on intimacy and openness, while men believe more in things as status and physical fitness being more important.
But is this so, is there really so much duality? There are hundreds of studies on gender differences put together in a meta-analysis, and there were still be some other results coming forward! They looked at the differences in language and feelings and guess what? Men and women were not as different as we previously were thinking. The conclusion is that men and women normally are psychologically seen the same. This rule has some exceptions, but these exceptions are not important in terms of friendships. What is particularly relevant for friendships is how easy intimate and frank a person with another person speaks. And about this fact, there were precisely these supposed men and women differences. But there appears to intimacy and frankness there is only a very small gender difference. Women were found "showing a little something more" of themselves than men.
The idea that there is a totally different between those friendships is a myth. It is often culturally rooted and we get to hear things now and learned at once from childhood. It is in fact a story that we tell each other about how it works and how it should be. And because we tell it, it occasionally will be true. Conclusion again: Yes we are brought up to think in stereotypes.
