> a recent study has moreover shown that poor health is associated not only with an earlier start of reproduction but also with an earlier initiation of sexual life in women and higher sexual desire in both women and men (skorov and flegr, 2021). at the same time, redheaded people have more children (frost et al., 2017), which would suggest an explanation based on a faster life strategy. it is possible that the faster life strategy of redheaded people could be partly indicated even at a prenatal stage by some physiological parameters which signalize a higher likelihood of future worse health. it has been shown, after all, that the link between red hair and worse health has a genetic component (han et al., 2006). rh-negativity, another genetic factor predisposing to worse health, has also been suggested as a factor that can lead to adoption of a faster life strategy (skorov and flegr, 2021) > the third model proposes that redheaded women have higher sexual desire and are sexually more permissive because the stereotypes about their sexual behavior have altered their self-perception. in this process, an initially incorrect attribution assigned by others can be internalized by the target person who then changes their self-perception to conform to the initially erroneous belief (snyder and swann, 1978; darley and fazio, 1980; mcnulty and swann, 1994; scherr et al., 2011). based on such process of change in self-perception, redheaded women themselves could be internally convinced of the validity of the stereotypical social labelling, which would then lead to their actual higher sexual desire > the fourth model puts potential mates, usually men, in the active role in explaining the association between womens redheadedness and their higher sexual activity
