In the case of blue-eyed parents, the color of a child’s eyes is a predictable and reliable genetic mechanism for determining inheritance. If men choose partners with characteristics that increase paternity confidence then blue-eyed men should find blue-eyed women more attractive than brown-eyed ones and mate with them to a greater extent than brown-eyed men. This hypothesis was tested and confirmed on a Norwegian sample by Laeng, Mathisen and Johnsen (2007). This study is an attempt to replicate this effect in the Croatian population, which differs in the ratio of eye color phenotypes (blue eye color is dominant in Norway while brown is dominant in Croatia). One hundred and twenty-eight participants (32 blue-eyed and brown-eyed men and women) assessed the attractiveness of blue-eyed and brown-eyed models, with the model's eye colors manipulated in such a way that each subject was shown a natural (eg. blue) or manipulated (eg. brown) eye color. The effect was successfully replicated, although it was smaller than in the study by Laeng et al. (2007). Blue-eyed men rated blue-eyed women as more attractive, while brown-eyed men and women, regardless of their own eye color, showed no differences in attractiveness assessments with respect to the model’s eye color. However, unlike the original study, in a sample of 138 participants no assortative pairing by eye color was found between participants and their romantic partners. Additionally, the hypothesis was tested that the effect of blue-eye preference will occur only in sociosexually restrictive blue-eyed men and those who exert a slower life-history strategy, since these individuals tend to show higher parental investment, so for them the risk of being cuckolded is higher. The hypothesis was confirmed for life-history strategies, but not for sociosexuality.
