Awhile ago, I suggested considering a composite of the Big Five personality traits Neuroticism and Agreeableness as an index of a feminine personality, since these two traits show the largest sex differences in all cultures. Thursday's typology of females is fairly similar.
Here I will take the sum of the two traits, but give different weights: I'm giving greater weight to Neuroticism to emphasize the part of female personality that makes her vulnerable, conscious of being evaluated, and lacking control over her emotions -- that is, what makes a girl most likely to fall head-over-heels in love. Specifically, I'm adding 4 parts Neuroticism and 1 part Agreeableness. If you wanted to emphasize the nurturing aspect of female personality, you would give greater weight to Agreeableness.
My aim is to help women approaching or over 30 snag a man, appealing to him on a romantic level, hence the emphasis on Neuroticism, which also signals youth. If you want to appeal to him on an "I'd be a great mother of your children" level, then you'd want to play up your Agreeableness -- and if you're 30 or older, you probably don't have to worry in this case, since the nurturing aspect of female personality increases steadily as the woman ages (I'll show the data for this some other time).
Still, I think the nurturing appeal is unlikely to help most women who need help: some do not want children anytime soon, some may be interested in a man who is unlikely to want to have children with them anytime soon, and so on. Unless he's a single father or both of you want kids right now, you'll have to appeal to him on a romantic level.
In the next part, I'll present some data on how this index of girliness changes across the lifespan. There are some obvious patterns (take a wild guess which age range shows the highest score), but there's also quite a surprise, one that may be good news for the women who need help.
