I can't vouch for the rigor of this research... but it certain accords with my own experiences of modern Western women! In particular, I think that years of politically correct claptrap in the media - in particular in women's magazines and newspaper collumns - has left women with totally unrealistic expectations of what men find attractive in a woman. In short, they project what THEY find attractive in a man, onto what they assume a man will find attractive in a woman. In essence: career success, material wealth, and 'worldliness' (i.e. experience, and how well travelled they are). You can quite see this in the way that women (particularly those in their 30s) describe themselves on dating sites (i.e. when they are trying to 'sell themselves'). Of course, the reality is that these qualities are not important at all for the vast majority of men who are looking for a relationship with a woman.
But does all this narcissism make women any happier? I would guess the exact reverse. And this accords with research I've read that shows that women are less likely than men to be happy. In general, I'd say that focusing on yourself is more likely to make you miserable, whilst focusing outwards onto the outside world, and loosing yourself in some external interest, is more likely to lead to contentment. And wasn't this, after all, the wisdom of philosophical movements like Buddhism? That you should try to forget your ego and loose yourself by focusing on other things?
