Using U.S. data from large national health surveys, we show that WHR, waist/thigh, waist/stature, and BMI are all lower in the age group (15-19) in which women reach physical and sexual maturity, after which all of these anthropometric measures increase.
Results showed that people looked at the head and chest more when assessing potential mates and looked at the legs and feet more when assessing potential friends.
The nubility hypothesis proposes that hominid females evolved protruding breasts because the size and shape of breasts function as an honest signal of residual reproductive value.
Here, we document that women with higher breast-to-underbreast ratio (large breasts) and women with relatively low WHR (narrow waists) have higher fecundity as assessed by precise measurements of daily levels of 17-beta-oestradiol (E2) and progesterone.
We found that as participants’ intrasexual competitiveness increased, they recommended cutting more hair off, particularly clients whose hair was in good condition and who wished to have as little cut off as possible, lending weight to the idea of sabotage through disingenuous beauty advice. Overall, more hair was recommended to be cut from low attractiveness clients than high attractiveness clients in the two-attractiveness-level study, suggesting downward competition in this particular scenario. However, this led us to the question how women
For men, the results show that being unattractive decreases the likelihood of finding a partner, of finding a partner with a university degree, and of finding a partner with a higher educational level. For women, physical attractiveness does not affect the likelihood of any of those events occurring.
The analysis of the National Longitudinal Study of Adolescent Health (Add Health) shows that very unattractive women were significantly more likely to be married at Age 29 than unattractive or average-looking women, and their spouses or partners earned significantly more than those of unattractive or average-looking women.
Findings from both adult and infant research suggest that there may be a universal standard of attractiveness, that of averageness. They then speculate about the mechanisms that could account for the development of attractiveness preferences and for the surprising fact that even young infants seem to recognize attractiveness in faces.
