Additional data points on this one are that "A certain amount of gender gap might be a natural artifact of a free society, where men and women finally can forge their own vocational paths."
Furthermore, this article says "It may seem like a cliche - or rank sexism - to say women like to work with people, and men prefer to work with things."
Seems reasonable to me. After all, if we stay with this argu=ment, then we also know that African Americans would prefer not to become CEOS or C-level executives; they stay out of those careers because they would simply prefer to do something else--NOT!!!!.
In other words, this is the most stupid, specious and circular arguement I have heard in a while, and I am embarassed a priestess of the journalism tribe would digest this booha whole and spit it back up for us,
Come on, woman, empirical reasoning does not rule!
Seems to me that when we make workplaces equal access and age/race/ and gender neutral, then we can ask these questions for real...otherwise, it's a question of whether you're willing to be the exception--or not.
