> psychologists and social scientists have also long studied group dynamics in mens vs womens teams...

If we are going down the researched stereotypical road, a group of 22 year old women has have more bullying, more social conflict, isolation tactics, and passive aggressiveness.

But do we really need to define group traits by gender if one is a few percent higher in competitiveness, other in bullying, and third in what kind of team building exercise that management think is suitable for their team? It all sound very stereotypical way of thinking about hiring procedures.

If we take a quick look at Sweden, there is this government department called Swedish Public Employment Service. A company sends in a list of requirements and they help to pick out suitable applicants. Seems like a good solution to the lifestyle hiring problem.
