Abstract
Women vary in the extent to which they prefer facial masculinity in a male partner, and much research has focused on explaining this variation systematically, with reference to the significance of men’s facial masculinity. Masculine-faced men provide some benefits (either real or perceived) as a romantic partner, but are perceived as less investing as parents. Accordingly, we investigated whether a UK-based sample of women (n = 366) had stronger preferences for male facial masculinity if they anticipated that their own parents would provide more time, money, and emotional investment in future grandchildren (i.e. the women’s future offspring), thereby alleviating any potential shortfall from the child’s father. In line with our hypothesis, we found that women had stronger preferences for men’s facial masculinity if the women anticipated that their fathers would provide more financial investment in their future grandchildren. We also found that women anticipated time, money, and emotional investment from their parents (particularly their mother) in their role as grandparents; given existing research findings on grandparental investment, participants’ anticipations are likely to be at least somewhat realistic.

Notes
In our case, the odds ratio (OR) equals the probability that the masculinized version is chosen divided by the probability that the feminized version is chosen. If p(masculinized) = 0.8 for any given trial, OR = 0.8/0.2 = 4.0, resulting in logit = 1.39. Conversely, p(masculinized) = 0.2 translates into OR = 0.2/0.8 = 0.25 and logit = − 1.39. Gelman and Hill (2006) and Sommet and Morselli (2017) provide accessible introductions.
To stick with the previous example, we use e−1.39 = 0.25 to convert our logit to its OR. We then use p = OR/(1 + OR) to revert this odds ratio to p = 0.2.
