The relationship between parents' stated sex preferences for children and actual parental behaviour towards sons and daughters is examined among the Mukogodo, a group of traditional pastoralists in rural Kenya. Although their cultural values are male-centred and they tend to express a preference for sons, Mukogodo parents actually appear to be more solicitous of daughters, and the Mukogodo have a strongly female-biased childhood sex ratio. Studies of stated sex preferences should therefore be coupled with attempts to assess actual (...) parental investment in sons and daughters. (shrink)

Contemporary mate preferences can provide important clues to human reproductive history. Little is known about which characteristics people value in potential mates. Five predictions were made about sex differences in human mate preferences based on evolutionary conceptions of parental investment, sexual selection, human reproductive capacity, and sexual asymmetries regarding certainty of paternity versus maternity. The predictions centered on how each sex valued earning capacity, ambition— industriousness, youth, physical attractiveness, and chastity. Predictions were tested in data from 37 samples (...) drawn from 33 countries located on six continents and five islands. For 27 countries, demographic data on actual age at marriage provided a validity check on questionnaire data. Females were found to value cues toresource acquisitionin potential mates more highly than males. Characteristics signalingreproductive capacitywere valued more by males than by females. These sex differences may reflect different evolutionary selection pressures on human males and females; they provide powerful cross-cultural evidence of current sex differences in reproductive strategies. Discussion focuses on proximate mechanisms underlying mate preferences, consequences for human intrasexual competition, and the limitations of this study. (shrink)

For nearly 70 years, studies have shown large sex differences in human mate selection preferences. However, most of the studies were restricted to a limited set of mate selection criteria and to college students, and neglecting relationship status. In this study, 21,245 heterosexual participants between 18 and 65 years of age (mean age 41) who at the time were not involved in a close relationship rated the importance of 82 mate selection criteria adapted from previous studies, reported age ranges (...) for the oldest and youngest partner that they would find acceptable, and responded to 10 yes/no questions about a potential marriage partner. For nearly all mate selection criteria, women were found to be the more demanding sex, although men placed consistently more value on the physical attractiveness of a potential partner than women. Also, the effects of the participants’ age and level of education were nearly negligible. These results demonstrate the robustness of sex differences in mate selection criteria across a substantial age range. (shrink)

The finding that women are attracted to men older than themselves whereas men are attracted to relatively younger women has been explained by social psychologists in terms of economic exchange rooted in traditional sex-role norms. An alternative evolutionary model suggests that males and females follow different reproductive strategies, and predicts a more complex relationship between gender and age preferences. In particular, males' preferences for relatively younger females should be minimal during early mating years, but should become more pronounced (...) as the male gets older. Young females are expected to prefer somewhat older males during their early years and to change less as they age. We briefly review relevant theory and present results of six studies testing this prediction. Study 1 finds support for this gender-differentiated prediction in age preferences expressed in personal advertisements. Study 2 supports the prediction with marriage statistics from two U.S. cities. Study 3 examines the cross-generational robustness of the phenomenon, and finds the same pattern in marriage statistics from 1923. Study 4 replicates Study 1 using matrimonial advertisements from two European countries, and from India. Study 5 finds a consistent pattern in marriages recorded from 1913 through 1939 on a small island in the Philippines. Study 6 reveals the same pattern in singles advertisements placed by financially successful American women and men. We consider the limitations of previous normative and evolutionary explanations of age preferences and discuss the advantages of expanding previous models to include the life history perspective.

On what we can call the “folk” conception of sexual orientation, sexual orientation is understood as sex-based attraction, that is, as (partly) attraction on the basis of the perceived sex of the person to whom one is attracted. However, in recent discussions, philosophers have either added gender to sex as the basis of sexual orientation, or have altogether replaced sex with gender. Moreover, this addition or replacement has gone—mostly—unargued for. This paper argues that a sex-based conception of sexual orientation remains (...) plausible because (1) it is compatible with gender-based attraction, which I argue can be understood as a preference; (2) the reasons so far on offer for adding gender to sex (or for replacing sex with gender) are not convincing; (3) we have good evolutionary and non-evolutionary reasons for thinking that sex is the basis of sexual orientation; (4) we have good reasons to not add gender as a basis of sexual orientation; and (5) a sex-based conception of sexual orientation accommodates the various sexual orientations that have recently appeared, orientations in addition to the folk two (or three) of heterosexuality, homosexuality (and bisexuality), such as pansexuality, skoliosexuality, gynsexuality, and androsexuality. What emerges is a conception of sexual orientation based (partly) on the sex of the people to whom we are attracted, but that understands sexual-based attraction in broad enough terms to include surgically altered bodies.

(1984). Gender Differences in Subject Preference and Perception of Subject Importance among Third Year Secondary School Pupils in Single‐sex and Mixed Comprehensive Schools. Educational Studies: Vol. 10, No. 3, pp. 243-253.

Research has found that both cisgender and transgender androphilic males (i.e., males sexually attracted to and aroused by other adult males) have female-typical occupational preferences when compared with gynephilic males (i.e., males sexually attracted to and aroused by adult females). Moreover, whereas cisgender androphilic males’ occupational preferences tend to be intermediate between those of gynephilic men and androphilic women, transgender androphilic males tend to have occupational preferences that are more similar to androphilic women. No study has directly (...) compared both types of androphilic males within the same culture. The present study investigated occupational preference and its relation to childhood sex-atypical behavior (CSAB), among gynephilic men (_n_ = 208), androphilic women (_n_ = 138), and cisgender (_n_ = 132) and transgender (_n_ = 129) androphilic males from the Istmo region of Oaxaca, Mexico, where androphilic males are recognized as third gender, _muxes_. The study found large sex differences in occupational preferences (_d_ = 2.80). Furthermore, both cisgender _muxe nguiiu_ (_d_ = 2.36) and transgender _muxe gunaa_ (_d_ = 3.44) reported having more sex-atypical occupational preferences compared with men. However, _muxe gunaa_ reported higher female-typical occupational preferences than women (_d_ = 0.59) and _muxe nguiiu_ (_d_ = 0.57), whereas _muxe nguiiu_ and women did not differ (_d_ = 0.08). These findings are consistent with the conclusion that sex-atypical occupational preferences are a cross-culturally universal aspect of male androphilia. Finally, CSAB was associated with sex-atypical occupational preferences among all participants. These findings suggest that a developmental continuity exists between childhood and adulthood sex-atypicality. (shrink)

This is a broad overview of how the prevalent family systems in the developing world influence sex preference for children. Son preference is evident in the data in East Asia and South Asia, and in the Middle East and North Africa, where patriarchal family systems make sons more valuable than daughters to parents in terms of economic, physical, and emotional sustenance. In sub-Saharan Africa, Latin America and Southeast Asia, there is little difference between the levels of support parents can expect (...) from sons and daughters—and little revealed sex preference in the data.

We show through analysis of personal advertisements that age preferences for a homosexual or lesbian partner are similar to differences found between men and women in age preferences for a opposite-sex partner. Such data call into question the claim by Kenrick & Keefe (1992) that the sex differences in age selectivity in mate selection are governed by reproductive strategies.

Wir diskutieren ethische Probleme der medizinischen Behandlung intersexueller Kinder. Gefragt wird nach dem Stellenwert von Elternwünschen nach eindeutiger Geschlechtszuweisung sowie nach den Konfliktfeldern, die zum einen zwischen konkurrierenden Wunschvorstellungen der Eltern und der behandelnden Ärzte, zum andern zwischen Kindeswohl und Kinderrechten entstehen können. Gegenwärtig wird Neugeborenen mit anatomisch uneindeutigem Genital trotz unsicherer Prognose über die Behandlungsergebnisse oft noch ein Geschlecht zugewiesen und operativ erstellt. Dieses Vorgehen ist von verschiedenen Seiten ethisch heftig kritisiert worden. Kipnis u. Diamond forderten 1998 im „Journal (...) of Clinical Ethics“ ein Moratorium für alle nicht vital indizierten geschlechtskorrigierenden Eingriffe. Diese Forderung orientiert sich am Interesse des zukünftigen Erwachsenen, betont dessen prospektive Autonomie und klammert den Elternwunsch aus. Dieses „Modell des antizipierten Konsenses“ kann jedoch mit Bezug auf Neugeborene und Kleinkinder bedeutsame Aspekte des Eltern-Kind-Verhältnisses nicht angemessen erfassen. Im Aufsatz werden Argumente angeführt, die es aus Sicht einer Ethik der Elternschaft rechtfertigen, ethische Entscheidungen auf der Basis eines beziehungsorientierten Modells zu treffen. In unserem Modell fallen Elternwünsche ethisch ins Gewicht. (shrink)

In a recent comment on the HFEA’s public consultation on sex selection, Soren Holm claimed that proponents of family balancing are committed to embrace a laissez faire approach. Given that arguments in support of sex selection for family balancing also support sex selection for other social reasons, advocates of family balancing, he asserts, are simply inconsistent when calling for a limit on access to sex selection. In this paper, I argue that proponents of family balancing are in no way inconsistent. (...) Provided their advocacy of family balancing is aimed at preventing a severe distortion of the natural sex ratio, they are entirely justified in insisting on restrictions to sex selection. The real question is whether a concern for the sex ratio does indeed call for a limit on sex selection. Based on a recent survey on gender preferences and data from several Gender Clinics, I argue that a restriction on sex selection to family balancing is unwarranted. In the absence of any evidence for a pending sex ratio distortion, we are actually required to adopt a laissez faire approach to sex selection. (shrink)

Non-medical sex selection is premised on the notion that the sexes are not interchangeable. Studies of individuals who undergo sex selection for non-medical reasons, or who have a preference for a son or daughter, show that they assume their child will conform to the stereotypical roles and norms associated with their sex. However, the evidence currently available has not succeeded in showing that the gender traits and inclinations sought are caused by a “male brain” or a “female brain”. Therefore, as (...) far as we know, there is no biological reason why parents cannot have the kind of parenting experience they seek with a child of any sex. Yet gender essentialism, a set of unfounded assumptions about the sexes which pervade society and underpin sexism, prevents parents from realising this freedom. In other words, unfounded assumptions about gender constrain not only a child’s autonomy, but also the parent’s. To date, reproductive autonomy in relation to sex selection has predominantly been regarded merely as the freedom to choose the sex of one’s child. This paper points to at least two interpretations of reproductive autonomy and argues that sex selection, by being premised on gender essentialism and/or the social pressure on parents to ensure their children conform to gender norms, undermines reproductive autonomy on both accounts.

Is sex work (specifically, prostitution) vulnerable to technological unemployment? Several authors have argued that it is. They claim that the advent of sophisticated sexual robots will lead to the displacement of human prostitutes, just as, say, the advent of sophisticated manufacturing robots have displaced many traditional forms of factory labour. But are they right? In this article, I critically assess the argument that has been made in favour of this displacement hypothesis. Although I grant the argument a degree of credibility, (...) I argue that the opposing hypothesis -- that prostitution will be resilient to technological unemployment -- is also worth considering. Indeed, I argue that increasing levels of technological unemployment in other fields may well drive more people into the sex work industry. Furthermore, I argue that no matter which hypothesis you prefer -- displacement or resilience -- you can make a good argument for the necessity of a basic income guarantee, either as an obvious way to correct for the precarity of sex work, or as a way to disincentivise those who may be drawn to prostitution.

The concept of biological sex guides research, clinical practice, science funding policy, and contemporary political discourse. Despite some substantive differences, all existing candidate philosophical accounts of sex assume its legitimacy as a biological concept. Here, we challenge this view. We argue against realism about biological sex, and that eliminating biological sex from large swaths of biological theory and practice may be preferable compared to conventionalist or fictionalist anti-realisms. There are serious social and epistemic costs to using “biological sex” in place (...) of more specific alternatives. Because of this, biologists and philosophers of science should consider eliminativism about the concept of biological sex. Biological sex eliminativism is worth taking seriously, and it can play important roles in philosophical debate and biological practice, even for those who remain skeptical. The methodological consequences of biological sex eliminativism are compatible with best practices for inquiry in the biological and biomedical sciences, with inclusive approaches to the study of sex and gender, and with feminist philosophical and methodological recommendations. Taking eliminativism seriously reveals important disagreement about the work that a concept of biological sex should do, and imposes a contrastive burden on would-be rivals. (shrink)

SummarySon preference has been considered as a determinant of women's risk of intimate partner violence experience in India, although quantitative evidence from large nationally representative studies testing this relationship is limited. This study examines the association between husband's son preference, sex composition of children and risk of physical and sexual IPV victimization among wives. Information was collected for 26,284 couples in the nationally representative 2005–2006 National Family Health Survey of India. The exposures were husband's son preference measured as husband's desire (...) for one or more sons greater than the number of daughters and sex composition of the household: only sons, only daughters and mixed. Outcome included past year physical and/or sexual IPV. The results showed that husband's reported son preference and sex composition of children were not associated with risk for IPV victimization in the models adjusted for socio-demographic factors. The findings from this first population-based study of socio-cultural norms around son preference and married Indian women's risk for IPV victimization indicate that cultural preference for sons does not influence women's risk for IPV victimization.

Some critics of same-sex marriage allege that this kind of union not only betrays the nature of marriage but that it also opens children to various kinds of harm. Same-sex marriage is objectionable, on this view, in its nature and in its effects. A view of marriage as requiring an unassisted capacity to conceive children may be respect as one idea of marriage, but this view need not be understood as marriage itself. It is not clear, in any case, why (...) government should prefer this one idealized view of marriage over other others, so long as recognition of other kinds of marriage do not stand in the way of government carrying out its core interests, such as the protection of children. The idea that children are necessarily harmed when conceived by and for same-sex couples cannot be sustained as a matter of psychological evidence or moral argument. No research shows that such children are routinely harmed or rarely-but-catastrophically. Comparative accounts of the welfare of children of same-sex couples cannot show either that children must be brought into existence only under ideal circumstances. (shrink)

ABSTRACT In this paper we argue that sex‐selective abortion (SSA) cannot be morally justified and that it should be prohibited. We present two main arguments against SSA. First, we present reasons why the decision for a woman to seek SSA in cultures with strong son‐preference cannot be regarded as autonomous on either a narrow or a broad account of autonomy. Second, we identify serious harms associated with SSA including perpetuation of discrimination against women, disruption to social and familial networks, and (...) increased violence against women. For these reasons, SSA should be prohibited by law, and such laws should be enforced. Finally, we describe additional strategies for decreasing son‐preference. Some of these strategies rely upon highlighting the disadvantages of women becoming scarce, such as lack of brides and daughters‐in‐law to care for elderly parents. We should, however, be cautious not to perpetuate the view that the purpose of women is to be the consorts for, and carers of, men, and the providers of children. Arguments against SSA should be located within a concerted effort to ensure greater, deeper social and cultural equality between the sexes. (shrink)

The literature on human mate preferences is vast but most data come from studies on college students in complex societies, who represent a thin slice of cultural variation in an evolutionarily novel environment. Here, I present data on the mate preferences of men and women in a society of hunter-gatherers, the Hadza of Tanzania. Hadza men value fertility in a mate more than women do, and women value intelligence more than men do. Women place great importance on men’s (...) foraging, and both sexes rate character as important. Unlike college students, Hadza men place considerable importance on women being hard-working, and Hadza women cite looks about as often as men do. (shrink)

This study examines child survival and growth in a patrilineal Ethiopian community as a function of father absence and sex. In line with evolutionary predictions for sex-biased parental investment, the absence of a father and associated constraints on household resources is more detrimental for sons’ than daughters’ survival in infancy. Father absence doubles a son’s risk of dying in infancy but has a positive influence on the well-being of female members of the household, improving daughter survival, growth, and maternal nutritional (...) status. Lack of paternal investment may be compensated for by other matrilateral kin through increased reciprocity between mother, daughter, and sister. (shrink)

The Progressive favors extending the legal institution of marriage so as to include same-sex unions along with heterosexual ones. The Traditionalist opposes such an extension, preferring to retain the legal institution of marriage in its present form. I argue that the Progressive ought to broaden her position, endorsing instead the Liberal case for extending the current institution so as to include polygamous unions as well—for any consideration favoring Progressivism over Traditionalism likewise favors Liberalism over Progressivism. Progressives inclined to resist Liberalism (...) are invited to consider an alternative position: the Libertarian stance that favors instead the ‘disestablishment’ of marriage. (shrink)

We examine whether sex discrimination contributes to the underrepresentation of female executives in large corporations. China’s strong cultural preference for sons has made newborn boys greatly outnumber newborn girls. Using the male-to-female sex ratio at birth as the proxy for discrimination against women, we find that firms headquartered in more discriminatory areas hire fewer female executives. Even conditional on a woman reaching an executive position, she faces a higher likelihood of dismissal and receives lower compensation than her male counterparts. Overall, (...) our findings suggest that sex discrimination plays an important role in preventing women from climbing the corporate ladder. (shrink)

Lonely hearts advertisements (LHA) published in Japan were examined in a comparative study on sexually dimorphic mate preference. I analyzed 944 LHA written by Japanese (730 by males and 214 by females) seeking short-term relationships and 780 LHA (577 by males and 203 by females) seeking long-term relationships. Some universal patterns of mate preference were confirmed and others were not. Female advertisers in both categories sought more traits than they offered; they also sought more traits than male advertisers. Males tended (...) to offer their financial and social status, and females tended to seek those traits. More females requested family commitment than males. While there was no sex difference in offering and seeking physical appearance and health, females tended to request photographs of their potential mates. Males were more likely than females to be willing to accept children from previous relationships, although there was no significant difference in refusing such children. More females seeking long-term mates requested family commitment than females seeking short-term mates. In both males and females, more advertisers seeking long-term mates offered family commitment than advertisers seeking short-term mates. Some predictions for contingent preference were also examined. One prediction confirmed was that females offering physical appearance and health sought more traits than those not doing so. However, males offering financial and social status did not make higher demands than those who did not, which does not support one prediction. (shrink)

Sex selection, which refers to the attempt to choose or control the sex of a child prior to its birth, has become the subject of increasing ethical scrutiny and many jurisdictions have criminalized it except for serious sex-linked diseases or conditions that cannot easily be ameliorated or remedied. This paper argues that such a blanket prohibition is ethically unwarranted because it is based on a flawed understanding of the difference between sexist values and mere sex-oriented preferences. It distinguishes between (...) ethics and public policy, and suggests a way of allowing preference-based sex selection as a matter of public policy without permitting value-based sex selection. It further argues that medically-based sex selection should be publicly funded but that preference-base sex selection should not be paid for by society, and that the prohibition against value-based sex selection should be enforced through legislation that controls the licensing of health care facilities and through disciplinary procedures against health care professionals.

The central premise is that a significant amount of sex offending stems from unusual or inappropriate sexual preferences that appear in early adolescence, are relatively stable, and immutable. In those ways, they are like more ordinary sexual preferences, generating sexual impulses that are insistent. Individuals are strongly tempted to act on them, alternatives to satisfying them are unfulfilling, and complete long-term control of such impulses is unlikely. Yet, since individuals with sexual preferences for inappropriate objects or activities (...) are neither morally nor legally permitted to act on them, they find themselves in a terrific bind. The public is, to some extent, correct to not trust the individuals with such preferences and to attempt to monitor or control them. However, most such efforts appear ineffective and counterproductive. Recidivist sex offenders are particularly worrisome. The possibility of voluntary castration for such offenders, in lieu of preventive detention or other more restrictive measures, is explored. (shrink)

On 9 May 2005, the Israeli Ministry of Health issued guidelines spelling out the conditions under which sex selection by preimplantation genetic diagnosis for social purposes is to be permitted in Israel. This article first reviews the available medical methods for sex selection, the preference for children of a specific gender in various societies and the ethical controversies surrounding PGD for medical and social purposes in different countries. It focuses then on the question of whether procreative liberty or parental responsibility (...) should be the centre of attention in this context. Finally, the article critically examines the new Israeli guidelines and their implications for the women undergoing the necessary medical treatments, for the children born as a result, for other members of the family and for society in general.

It is hypothesized from within an evolutionary framework that females should be less invested in peer relations than males. Investment was operationalized as enjoyment in Study 1 and as preference for interaction in Study 2. In the first study, four- and six-year-old children’s enjoyment of peer interaction was observed in 26 groups of same-sex peers. Girls were rated as enjoying their interactions significantly less than boys. In the second study, six- and nine-year-old children were interviewed about the individuals with whom (...) they spend time in their homes and neighborhoods and about the individuals who participate in their favorite activities. The proportion of individuals named by children who were peers was significantly lower for girls than boys both in children’s neighborhoods and in children’s favorite activities. Results strongly support the hypothesis that females and males have evolved differential preferences for interaction with peers. (shrink)

After China, India has the most skewed sex ratio at birth. These two Asian countries account for about 90 to 95% of the estimated 1.2 to 1.5 million missing female births annually, worldwide, due to gender-biased sex selection. To understand this extreme discrimination against girls, this article examines the gendered biopolitics embedded in population policies, new sex selection technologies, and in the social reproduction of patriarchal society. The ethical consequences of advanced reproductive technologies, which remove the moral turpitude around gender-based (...) sex selection by reformulating it into a “modern”, “scientific” endeavour, facilitating the rise of “missing girls”, make this an issue of gender justice, as noted by the World Population Report 2020. This article argues that unpacking gendered biopolitics within the household is crucial to understanding the reproduction of son preference and daughter aversion since it is here that reproduction and parenthood are subjected to biopolitical governance. We discuss how “biosocial” strategies of the household aimed at producing the “desired” and “right” family of more sons at the cost of daughters are operationalized through women’s bodies with a view to family mobility. While women and girls continue to bear the burden and costs of social reproduction that lie at the heart of the patriarchal capitalist system of accumulation, a perusal of more recent studies suggests the beginning of an equalizing trend of parental investments, especially in the health and education of daughters who are “allowed” to be born. We suggest that familial enhancement of girls’ human capital can help as a means of developing girls’ capabilities and agency, enhancing their power in the biopolitics of the family and increasing their “bio-value” in parents’ eyes.

Ethical decisions are contextualized in the dialectic of a multidimensional system, including situation, setting, culture, and generation. There may be further gaps between the ethical considerations of professionals and folk values. The experience of promoting equal opportunities in Hong Kong illustrates some of these challenges. Whereas the rule of law under a Western legal system advocates human rights, the traditional emphasis on harmony and preference for balancing in conflict resolution underlie the gaps in the interpretation of these ideals. The case (...) of the Hong Kong secondary school places allocation system highlights the conflicting perspectives of law, gender stereotypes, psychological knowledge, as well as ethical principles of justice and fairness in promoting equal opportunities in educational assessment and placement. The cultural perspective highlighted in this case illustrates the complex contexts of ethical decisions. (shrink)

The present study examined the relationship between left–right discrimination (LRD) performance and handedness, sex and cognitive abilities. In total, 31 men and 35 women – with a balanced ratio of left-and right-handers – completed the Bergen Left–Right Discrimination Test. We found an advantage of left-handers in both identifying left hands and in verifying “left” propositions. A sex effect was also found, as women had an overall higher error rate than men, and increasing difficulty impacted their reaction time more than it (...) did for men. Moreover, sex interacted with handedness and manual preference strength. A negative correlation of LRD reaction time with visuo-spatial and verbal long-term memory was found independently of sex, providing new insights into the relationship between cognitive skills and performance on LRD.

Although scientific interest in facial attractiveness has developed substantially in recent years, few studies have contributed to our understanding of the ontogeny of facial preferences. In this study, attractiveness of 30 male faces was evaluated by four female groups: girls at puberty, nonpregnant and pregnant young women, and middle-aged women. The main findings are as follows: (1) Preference for sexy-looking faces was strongest in young, nonpregnant women. (2) Biologically more mature girls displayed more adultlike preferences. (3) The intragroup (...) consistency for postmenopausal women was relatively low. (4) In terms of the preference pattern, pregnant women were more similar to perimenopausal women than they were to their nonpregnant peers. (5) Preference for youthful appearance decreased with the age of the women. I argue that the life history of female preferences for male faces is, to a large extent, hormone-driven and underpinned by a set of evolutionary adaptations. (shrink)
