One of the most useful ideas that Susan Pinker reports in The Sexual Paradox comes from Catherine Hakim's work on the distribution of women's preferences. Hakim calculates that about 20% of women are career-centered and 20% are home-centered. The 60% in the middle are "adaptive," trying to have it all, tacking between two poles. Hakim’s Preference Theory: not all women want the same thing, and only 20% want what men want.
This also means that in general, women are less likely to have a career plan than men. In particular, women’s plans are more likely to change after children than men’s. Men like to tell the story of their careers as their following a plan, overcoming obstacles. Women are more likely to describe their lives are a natural flow of one event into another, many of the turns not planned but not bad.
