    Understanding Sex and Gender

    Learning Objectives
    1. Define sex, gender, femininity, and masculinity.
    2. Critically assess the evidence on biology, culture and socialization, and gender.
    3. Discuss agents of gender socialization.

    Although the terms sex and gender are sometimes used interchangeably and do complement each other, they nonetheless refer to different aspects of what it means to be a woman or man in any society.

    Sex refers to the anatomical and other biological differences between females and males that are determined at the moment of conception and develop in the womb and throughout childhood and adolescence. Females, of course, have two X chromosomes, while males have one X chromosome and one Y chromosome. From this basic genetic difference spring other biological differences. The first to appear are the genitals that boys and girls develop in the womb and that the doctor (or midwife) and parents look for when a baby is born (assuming the baby’s sex is not already known from ultrasound or other techniques) so that the momentous announcement, “It’s a boy!” or “It’s a girl!” can be made. The genitalia are called primary sex characteristics, while the other differences that develop during puberty are called secondary sex characteristics and stem from hormonal differences between the two sexes. Boys generally acquire deeper voices, more body hair, and more muscles from their flowing testosterone. Girls develop breasts and wider hips and begin menstruating as nature prepares them for possible pregnancy and childbirth. For better or worse, these basic biological differences between the sexes affect many people’s perceptions of what it means to be female or male, as we next discuss.

    Gender as a Social Construction

    If sex is a biological concept, then gender is a social concept. It refers to the social and cultural differences a society assigns to people based on their (biological) sex. A related concept, gender roles, refers to a society’s expectations of people’s behavior and attitudes based on whether they are females or males. Understood in this way, gender, like race as discussed in Chapter 3, is a social construction. How we think and behave as females and males is not etched in stone by our biology but rather is a result of how society expects us to think and behave based on what sex we are. As we grow up, we learn these expectations as we develop our gender identity, or our beliefs about ourselves as females or males.

    These expectations are called femininity and masculinity. Femininity refers to the cultural expectations we have of girls and women, while masculinity refers to the expectations we have of boys and men. A familiar nursery rhyme nicely summarizes these two sets of traits:

    What are little boys made of ?

    Snips and Snails
    And puppy dog tails
    That's what little boys are made of ?
    What are little girls made of ?
    Sugar and spice
    And everything nice
    That's what little girls are made of

    As this rhyme suggests, our traditional notions of femininity and masculinity indicate that we think females and males are fundamentally different from each other. In effect, we think of them as two sides of the same coin of being human. What we traditionally mean by femininity is captured in the adjectives, both positive and negative, we traditionally ascribe to women: gentle, sensitive, nurturing, delicate, graceful, cooperative, decorative, dependent, emotional, passive, and weak. Thus when we say that a girl or woman is very feminine, we have some combination of these traits in mind: she is soft, dainty, pretty, and even a bit flighty. What we traditionally mean by masculinity is captured in the adjectives, again both positive and negative, our society traditionally ascribes to men: strong, assertive, brave, active, independent, intelligent, competitive, insensitive, unemotional, and aggressive. When we say that a boy or man is very masculine, we have some combination of these traits in mind: he is tough, strong, and assertive.

    These traits might sound like stereotypes of females and males in today’s society, and to some extent they are, but differences between women and men in attitudes and behavior do in fact exist (Aulette & Wittner, 2011).Aulette, J. R., & Wittner, J. (2011). Gendered worlds (2nd ed.). New York, NY: Oxford University Press. For example, women cry more often than men do. Men are more physically violent than women. Women take care of children more than men do. Women smile more often than men. Men curse and spit more often than women. When women talk with each other, they are more likely to talk about their personal lives than men are when they talk with each other. The two sexes even differ when they hold a cigarette (not that anyone should smoke!). When a woman holds a cigarette, she usually has the palm of her cigarette-holding hand facing upward; when a man holds a cigarette, he usually has his palm facing downward.

    The Development of Gender Differences

    What accounts for differences in female and male behavior and attitudes? Do the biological differences between the sexes account for these other differences? Or do these latter differences stem, as most sociologists think, from cultural expectations and from differences in the ways in which the sexes are socialized? These are critical questions, for they ask whether the differences between boys and girls and women and men stem more from biology or from society. If we think behavioral and other differences between the sexes are due primarily to their respective biological makeups, we imply that these differences are inevitable or nearly so and that any attempt to change them goes against biology and will likely fail.

    For example, consider the obvious biological fact that women bear and nurse children and men do not. Couple this with the common view that women are also more gentle and nurturing than men, and we end up with a “biological recipe” for women to be the primary caretakers of children. Many people think this means women are therefore much better suited than men to take care of children once they are born, and that the family might be harmed if mothers work outside the home or if fathers are the primary caretakers. Figure 4.1 shows that more than one-third of the public agrees that “it is much better for everyone involved if the man is the achiever outside the home and the woman takes care of the home and family.” To the extent this belief exists, women may not want to work outside the home or, if they choose to do so, they then face difficulties from employers, family, and friends. Conversely, men may not even think about wanting to stay at home and may themselves face difficulties from employees, family, and friends if they want to do so. A belief in a strong biological basis for differences between women and men implies, then, that there is little we can or should do to change these differences. It implies that “anatomy is destiny,” and destiny is, of course, by definition inevitable.

    This implication makes it essential to understand the extent to which gender differences do, in fact, stem from biological differences between the sexes or, instead, stem from cultural and social influences. If biology is paramount, then gender differences are perhaps inevitable and the status quo will remain. If culture and social influences matter much more than biology, then gender differences can change and the status quo may give way. With this backdrop in mind, let’s turn to the biological evidence for behavioral and other differences between the sexes and then examine the evidence for their social and cultural roots.

    Biology and Gender

    Several biological explanations for gender roles exist, and we discuss two of the most important ones here. One explanation is from the field of evolutionary psychology (Buss, 2012)Buss, D. (2012). Evolutionary psychology: The new science of the mind (4th ed.). Upper Saddle River, NJ: Pearson. and argues an evolutionary basis for traditional gender roles.

    Scholars advocating this view reason as follows (Thornhill & Gangestad, 2008).Thornhill, R., & Gangestad, S. W. (2008). The evolutionary biology of human female sexuality. New York, NY: Oxford University Press. In prehistoric societies, two major social roles existed (1) hunting or gathering food to relieve hunger, and (2) bearing and nursing children. Because only women could perform the latter role, they were also the primary caretakers for children for several years after birth. And because women were frequently pregnant, their roles as mothers confined them to the home. Meanwhile, men were better suited than women for hunting because they were stronger and quicker than women. In prehistoric societies, then, biology was indeed destiny: For biological reasons, men in effect worked outside the home (hunted), while women stayed at home with their children.

    Evolutionary reasons also explain why men are more violent than women. In prehistoric times, men who were more willing to commit violence against and even kill other men would “win out” in the competition for female mates. They thus were more likely than less violent men to produce offspring, who would then carry these males’ genetic violent tendencies.

    If the human race evolved along these lines, evolutionary psychologists continue, natural selection favored those societies where men were stronger, braver, and more aggressive and where women were more fertile and nurturing. Such traits over the millennia became fairly instinctual, meaning that men’s and women’s biological natures evolved differently. Men became, by nature, more assertive, daring, and violent than women, and women became, by nature, more gentle, nurturing, and maternal than men. To the extent this is true, these scholars add, traditional gender roles for women and men make sense from an evolutionary standpoint, and attempts to change them go against the sexes’ biological natures. This in turn implies that existing gender inequality must continue because it is rooted in biology. The title of a book presenting the evolutionary psychology argument summarizes this implication: “Biology at Work: Rethinking Sexual Equality” (Browne, 2002).Browne, K. (2002). Biology at work: Rethinking sexual equality. New Brunswick, NJ: Rutgers University Press.

    Critics challenge the evolutionary explanation on several grounds (Begley, 2009; Fine, 2011).Begley, S. (2009, June 29). Don’t blame the caveman. Newsweek, 52–62; Fine, C. (2011). Delusions of gender: The real science behind sex differences. New York, NY: W. W. Norton. First, much greater gender variation in behavior and attitudes existed in prehistoric times than the evolutionary explanation assumes. Second, even if biological differences did influence gender roles in prehistoric times, these differences are largely irrelevant in modern societies, in which, for example, physical strength is not necessary for survival. Third, human environments throughout the millennia have simply been too diverse to permit the simple, straightforward biological development that the evolutionary explanation assumes. Fourth, evolutionary arguments implicitly justify existing gender inequality by implying the need to confine women and men to their traditional roles.

    Recent anthropological evidence also challenges the evolutionary argument that men’s tendency to commit violence was biologically transmitted. This evidence instead finds that violent men have trouble finding female mates who would want them and that the female mates they find and the children they produce are often killed by rivals to the men (Begley, 2009).Begley, S. (2009, June 29). Don’t blame the caveman. Newsweek, 52–62.

    A second biological explanation for traditional gender roles attributes males’ higher levels of aggression to their higher levels of testosterone (Mazur, 2009).Mazur, A. (2009). Testosterone and violence among young men. In A. Walsh & K. M. Beaver (Eds.), Biosocial criminology: New directions in theory and research (pp. 190–204). New York, NY: Routledge. Several studies find that males with higher levels of testosterone tend to have higher levels of aggression. However, this correlation does not necessarily mean that their testosterone increased their violence; as has been found in various animal species, it is also possible that their violence increased their testosterone. Because studies of human males cannot for ethical and practical reasons manipulate their testosterone levels, the exact meaning of the results from these testosterone-aggression studies must remain unclear, according to a report by the National Academy of Sciences (Miczek, Mirsky, Carey, DeBold, & Raine, 1994).Miczek, K. A., Mirsky, A. F., Carey, G., DeBold, J., & Raine, A. (1994). An overview of biological influences on violent behavior. In J. Albert, J. Reiss, K. A. Miczek & J. A. Roth (Eds.), Understanding and preventing violence: Biobehavioral influences (Vol. 2, pp. 1–20). Washington, DC: National Academy Press.

    Another line of research on the biological basis for sex differences in aggression involves children, including some as young as ages 1 or 2, in various situations (Card, Stucky, Sawalani, & Little, 2008).Card, N. A., Stucky, B. D., Sawalani, G. M., & Little, T. D. (2008). Direct and indirect aggression during childhood and adolescence: A meta-analytic review of gender differences, intercorrelations, and relations to maladjustment. Child Development, 79(5), 1185–1229. They might be playing with each other, interacting with adults, or writing down solutions to hypothetical scenarios given to them by a researcher. In most of these studies, boys are more physically aggressive in thought or deed than girls, even at a very young age. Other studies are more experimental in nature. In one type of study, a toddler will be playing with a toy, only to have it removed by an adult. Boys typically tend to look angry and try to grab the toy back, while girls tend to just sit there and whimper. Because these gender differences in aggression are found at very young ages, researchers often say they must have some biological basis. However, critics of this line of research counter that even young children have already been socialized along gender lines (Begley, 2009; Fine, 2011),Begley, S. (2009, September 14). Pink brain, blue brain: Claims of sex differences fall apart. Newsweek, 28; Fine, C. (2011). Delusions of gender: The real science behind sex differences. New York, NY: W. W. Norton. a point to which we return later in the chapter. To the extent this is true, gender differences in children’s aggression may reflect socialization rather than biology.

    In sum, biological evidence for gender differences certainly exists, but its interpretation remains very controversial. It must be weighed against the evidence, to which we next turn, of cultural variations in the experience of gender and of socialization differences by gender. One thing is clear: To the extent we accept biological explanations for gender, we imply that existing gender differences and gender inequality must continue to exist. As sociologist Linda L. Lindsey (2011, p. 52)Lindsey, L. L. (2011). Gender roles: A sociological perspective (5th ed.). Upper Saddle River, NJ: Prentice Hall. notes, “Biological arguments are consistently drawn upon to justify gender inequality and the continued oppression of women.” In contrast, cultural and social explanations of gender differences and gender inequality promise some hope for change. Let’s examine the evidence for these explanations.
