Looking back. With surveys on women and men college job picks, we could put down a 'maybe' to a 'yes' for that. There are more women working in nursing, caring and education. And there are more men working in driving, construction and manual labor.
I wouldn't call it a 'trait', but I would call it a 'trend'. There is clearly a trend between women and men that they have different preferences. Those preferences cause unbalance diversity in exchange for different strength.
