Every time I see any discourse about this OK Cupid graph I always think that the correct comparison shouldn't be how men rate women vs how women rate men, it should be how do women vs gay men rate men, and how do men vs gay women rate women. It seems obvious to me that women's average would be higher on the scale, since as Poitr points out women in general spend much more time working to improve their rating (and also have access to an easier socially acceptable way to do so in makeup)
