The Blank Slate: The Modern Denial of Human Nature

  Feminism is widely seen as being opposed to the sciences of human nature. Many of those scientists believe that the minds of the two sexes differ at birth, and feminists have pointed out that such beliefs have long been used to justify the unequal treatment of women. Women were thought to be designed for childrearing and home life and to be incapable of the reason necessary for politics and the professions. Men were believed to harbor irresistible urges that made them harass and rape women, and that belief served to excuse the perpetrators and to license fathers and husbands to control women in the guise of protecting them. Therefore, it might seem, the theories that are most friendly to women are the Blank Slate—if nothing is innate, differences between the sexes cannot be innate—and the Noble Savage—if we harbor no ignoble urges, sexual exploitation can be eliminated by changing our institutions.

  The belief that feminism requires a blank slate and a noble savage has become a powerful impetus for spreading disinformation. A 1994 headline in the New York Times science section, for example, proclaimed, “Sexes Equal on South Sea Isle.”3 It was based on the work of the anthropologist Maria Lepowsky, who (perhaps channeling the ghost of Margaret Mead) said that gender relations on the island of Vanatinai prove that “the subjugation of women by men is not a human universal, and it is not inevitable.” Only late in the story do we learn what this supposed “equality” amounts to: that men must do bride service to pay for wives, that warfare had been waged exclusively by men (who raided neighboring islands for brides), that women spend more time caring for children and sweeping up pig excrement, and that men spend more time building their reputations and hunting wild boar (which is accorded more prestige by both sexes). A similar disconnect between headline and fact appeared in a 1998 Boston Globe story entitled “Girls Appear to Be Closing Aggression Gap with Boys.” How much have they “closed this gap”? According to the story, they now commit murder at one-tenth the rate of boys.4 And in a 1998 op-ed, the co-producer of Ms. magazine’s “Take Our Daughters to Work Day” explained recent high school shootings with the remarkable assertion that boys in America “are being trained by their parents, other adults, and our culture and media to harass, assault, rape, and murder girls.”5

  On the other side, some conservatives are confirming feminists’ worst fears by invoking dubious sex differences to condemn the choices of women. In a Wall Street Journal editorial, the political scientist Harvey Mansfield wrote that “the protective element of manliness is endangered by women having equal access to jobs outside the home.”6 A book by F. Carolyn Graglia called Domestic Tranquility: A Brief Against Feminism theorized that women’s maternal and sexual instincts are being distorted by the assertiveness and analytical mind demanded by a career. The journalists Wendy Shalit and Danielle Crittenden recently advised women to marry young, postpone their careers, and care for children in traditional marriages, even though they could not have written their books if they had followed their own advice.7 Leon Kass has taken it upon himself to inform young women what they want: “For the first time in human history, mature women by the tens of thousands live the entire decade of their twenties—their most fertile years—neither in the homes of their fathers nor in the homes of their husbands; unprotected, lonely, and out of sync with their inborn nature. Some women positively welcome this state of affairs, but most do not.”8

  There is, in fact, no incompatibility between the principles of feminism and the possibility that men and women are not psychologically identical. To repeat: equality is not the empirical claim that all groups of humans are interchangeable; it is the moral principle that individuals should not be judged or constrained by the average properties of their group. In the case of gender, the barely defeated Equal Rights Amendment put it succinctly: “Equality of Rights under the law shall not be denied or abridged by the United States or any state on account of sex.” If we recognize this principle, no one has to spin myths about the indistinguishability of the sexes to justify equality. Nor should anyone invoke sex differences to justify discriminatory policies or to hector women into doing what they don’t want to do.

  In any case, what we do know about the sexes does not call for any action that would penalize or constrain one sex or the other. Many psychological traits relevant to the public sphere, such as general intelligence, are the same on average for men and women, and virtually all psychological traits may be found in varying degrees among the members of each sex. No sex difference yet discovered applies to every last man compared with every last woman, so generalizations about a sex will always be untrue of many individuals. And notions like “proper role” and “natural place” are scientifically meaningless and give no grounds for restricting freedom.

  Despite these principles, many feminists vehemently attack research on sexuality and sex differences. The politics of gender is a major reason that the application of evolution, genetics, and neuroscience to the human mind is bitterly resisted in modern intellectual life. But unlike other human divisions such as race and ethnicity, where any biological differences are minor at most and scientifically uninteresting, gender cannot possibly be ignored in the science of human beings. The sexes are as old as complex life and are a fundamental topic in evolutionary biology, genetics, and behavioral ecology. To disregard them in the case of our own species would be to make a hash of our understanding of our place in the cosmos. And of course differences between men and women affect every aspect of our lives. We all have a mother and a father, are attracted to members of the opposite sex (or notice our contrast with the people who are), and are never unaware of the sex of our siblings, children, and friends. To ignore gender would be to ignore a major part of the human condition.

  The goal of this chapter is to clarify the relation between the biology of human nature and current controversies on the sexes, including the two most incendiary, the gender gap and sexual assault. With both of these hot buttons, I will argue against the conventional wisdom associated with certain people who claim to speak on behalf of feminism. That may create an illusion that the arguments go against feminism in general, or even against the interests of women. They don’t in the least, and I must begin by showing why.

  FEMINISM IS OFTEN derided because of the arguments of its lunatic fringe—for example, that all intercourse is rape, that all women should be lesbians, or that only 10 percent of the population should be allowed to be male.9 Feminists reply that proponents of women’s rights do not speak with one voice, and that feminist thought comprises many positions, which have to be evaluated independently.10 That is completely legitimate, but it cuts both ways. To criticize a particular feminist proposal is not to attack feminism in general.

  Anyone familiar with academia knows that it breeds ideological cults that are prone to dogma and resistant to criticism. Many women believe that this has now happened to feminism. In her book Who Stole Feminism? the philosopher Christina Hoff Sommers draws a useful distinction between two schools of thought.11 Equity feminism opposes sex discrimination and other forms of unfairness to women. It is part of the classical liberal and humanistic tradition that grew out of the Enlightenment, and it guided the first wave of feminism and launched the second wave. Gender feminism holds that women continue to be enslaved by a pervasive system of male dominance, the gender system, in which “bi-sexual infants are transformed into male and female gender personalities, the one destined to command, the other to obey.”12 It is opposed to the classical liberal tradition and allied instead with Marxism, postmodernism, social constructionism, and radical science. It has became the credo of some women’s studies programs, feminist organizations, and spokespeople for the women’s movement.

  Equity feminism is a moral doctrine about equal treatment that makes no commitments regarding open empirical issues in psychology or biology. Gender feminism is an empirical doctrine committed to three claims about human nature. The first is that the differences between men and women have nothing to do with biology but are socially constructed in their entirety. The
second is that humans possess a single social motive—power—and that social life can be understood only in terms of how it is exercised. The third is that human interactions arise not from the motives of people dealing with each other as individuals but from the motives of groups dealing with other groups—in this case, the male gender dominating the female gender.

  In embracing these doctrines, the genderists are handcuffing feminism to railroad tracks on which a train is bearing down. As we shall see, neuroscience, genetics, psychology, and ethnography are documenting sex differences that almost certainly originate in human biology. And evolutionary psychology is documenting a web of motives other than group-against-group dominance (such as love, sex, family, and beauty) that entangle us in many conflicts and confluences of interest with members of the same sex and of the opposite sex. Gender feminists want either to derail the train or to have other women join them in martyrdom, but the other women are not cooperating. Despite their visibility, gender feminists do not speak for all feminists, let alone for all women.

  To begin with, research on the biological basis of sex differences has been led by women. Because it is so often said that this research is a plot to keep women down, I will have to name names. Researchers on the biology of sex differences include the neuroscientists Raquel Gur, Melissa Hines, Doreen Kimura, Jerre Levy, Martha McClintock, Sally Shaywitz, and Sandra Witelson and the psychologists Camilla Benbow, Linda Gottfredson, Diane Halpern, Judith Kleinfeld, and Diane McGuinness. Sociobiology and evolutionary psychology, sometimes stereotyped as a “sexist discipline,” is perhaps the most bi-gendered academic field I am familiar with. Its major figures include Laura Betzig, Elizabeth Cashdan, Leda Cosmides, Helena Cronin, Mildred Dickeman, Helen Fisher, Patricia Gowaty, Kristen Hawkes, Sarah Blaffer Hrdy, Magdalena Hurtado, Bobbie Low, Linda Mealey, Felicia Pratto, Marnie Rice, Catherine Salmon, Joan Silk, Meredith Small, Barbara Smuts, Nancy Wilmsen Thornhill, and Margo Wilson.

  It is not just gender feminism’s collision with science that repels many feminists. Like other inbred ideologies, it has produced strange excrescences, like the offshoot known as difference feminism. Carol Gilligan has become a gender-feminist icon because of her claim that men and women guide their moral reasoning by different principles: men think about rights and justice; women have feelings of compassion, nurturing, and peaceful accommodation.13 If true, it would disqualify women from becoming constitutional lawyers, Supreme Court justices, and moral philosophers, who make their living by reasoning about rights and justice. But it is not true. Many studies have tested Gilligan’s hypothesis and found that men and women differ little or not at all in their moral reasoning.14 So difference feminism offers women the worst of both worlds: invidious claims without scientific support. Similarly, the gender-feminist classic called Women’s Ways of Knowing claims that the sexes differ in their styles of reasoning. Men value excellence and mastery in intellectual matters and skeptically evaluate arguments in terms of logic and evidence; women are spiritual, relational, inclusive, and credulous.15 With sisters like these, who needs male chauvinists?

  Gender feminism’s disdain for analytical rigor and classical liberal principles has recently been excoriated by equity feminists, among them Jean Bethke Elshtain, Elizabeth Fox-Genovese, Wendy Kaminer, Noretta Koertge, Donna Laframboise, Mary Lefkowitz, Wendy McElroy, Camille Paglia, Daphne Patai, Virginia Postrel, Alice Rossi, Sally Satel, Christina Hoff Sommers, Nadine Strossen, Joan Kennedy Taylor, and Cathy Young.16 Well before them, prominent women writers demurred from gender-feminist ideology, including Joan Didion, Doris Lessing, Iris Murdoch, Cynthia Ozick, and Susan Sontag.17 And ominously for the movement, a younger generation has rejected the gender feminists’ claims that love, beauty, flirtation, erotica, art, and heterosexuality are pernicious social constructs. The title of the book The New Victorians: A Young Woman’s Challenge to the Old Feminist Order captures the revolt of such writers as Rene Denfeld, Karen Lehrman, Katie Roiphe, and Rebecca Walker, and of the movements called Third Wave, Riot Grrrl Movement, Pro-Sex Feminism, Lipstick Lesbians, Girl Power, and Feminists for Free Expression.18

  The difference between gender feminism and equity feminism accounts for the oft-reported paradox that most women do not consider themselves feminists (about 70 percent in 1997, up from about 60 percent a decade before), yet they agree with every major feminist position.19 The explanation is simple: the word “feminist” is often associated with gender feminism, but the positions in the polls are those of equity feminism. Faced with these signs of slipping support, gender feminists have tried to stipulate that only they can be considered the true advocates of women’s rights. For example, in 1992 Gloria Steinem said of Paglia, “Her calling herself a feminist is sort of like a Nazi saying they’re not anti-Semitic.”20 And they have invented a lexicon of epithets for what in any other area would be called disagreement: “backlash,” “not getting it,” “silencing women,” “intellectual harassment.”21

  All this is an essential background to the discussions to come. To say that women and men do not have interchangeable minds, that people have desires other than power, and that motives belong to individual people and not just to entire genders is not to attack feminism or to compromise the interests of women, despite the misconception that gender feminism speaks in their name. All the arguments in the remainder of this chapter have been advanced most forcefully by women.

  WHY ARE PEOPLE SO afraid of the idea that the minds of men and women are not identical in every respect? Would we really be better off if everyone were like Pat, the androgynous nerd from Saturday Night Live? The fear, of course, is that different implies unequal—that if the sexes differed in any way, then men would have to be better, or more dominant, or have all the fun.

  Nothing could be farther from biological thinking. Trivers alluded to a “symmetry in human relationships,” which embraced a “genetic equality of the sexes.”22 From a gene’s point of view, being in the body of a male and being in the body of a female are equally good strategies, at least on average (circumstances can nudge the advantage somewhat in either direction).23 Natural selection thus tends toward an equal investment in the two sexes: equal numbers, an equal complexity of bodies and brains, and equally effective designs for survival. Is it better to be the size of a male baboon and have six-inch canine teeth or to be the size of a female baboon and not have them? Merely to ask the question is to reveal its pointlessness. A biologist would say that it’s better to have the male adaptations to deal with male problems and the female adaptations to deal with female problems.

  So men are not from Mars, nor are women from Venus. Men and women are from Africa, the cradle of our evolution, where they evolved together as a single species. Men and women have all the same genes except for a handful on the Y chromosome, and their brains are so similar that it takes an eagle-eyed neuroanatomist to find the small differences between them. Their average levels of general intelligence are the same, according to the best psychometric estimates,24 and they use language and think about the physical and living world in the same general way. They feel the same basic emotions, and both enjoy sex, seek intelligent and kind marriage partners, get jealous, make sacrifices for their children, compete for status and mates, and sometimes commit aggression in pursuit of their interests.

  But of course the minds of men and women are not identical, and recent reviews of sex differences have converged on some reliable differences.25 Sometimes the differences are large, with only slight overlap in the bell curves. Men have a much stronger taste for no-strings sex with multiple or anonymous partners, as we see in the almost all-male consumer base for prostitution and visual pornography.26 Men are far more likely to compete violently, sometimes lethally, with one another over stakes great and small (as in the recent case of a surgeon and an anesthesiologist who came to blows in the operating room while a patient lay on the table waiting to have her gall bladder removed).27 Among children, boys spend far more time practicing for violent conflict in the form
of what psychologists genteelly call “rough-and-tumble play.”28 The ability to manipulate three-dimensional objects and space in the mind also shows a large difference in favor of men.29

  With some other traits the differences are small on average but can be large at the extremes. That happens for two reasons. When two bell curves partly overlap, the farther out along the tail you go, the larger the discrepancies between the groups. For example, men on average are taller than women, and the discrepancy is greater for more extreme values. At a height of five foot ten, men outnumber women by a ratio of thirty to one; at a height of six feet, men outnumber women by a ratio of two thousand to one. Also, confirming an expectation from evolutionary psychology, for many traits the bell curve for males is flatter and wider than the curve for females. That is, there are proportionally more males at the extremes. Along the left tail of the curve, one finds that boys are far more likely to be dyslexic, learning disabled, attention deficient, emotionally disturbed, and mentally retarded (at least for some types of retardation).30 At the right tail, one finds that in a sample of talented students who score above 700 (out of 800) on the mathematics section of the Scholastic Assessment Test, boys outnumber girls by thirteen to one, even though the scores of boys and girls are similar within the bulk of the curve.31

  With still other traits, the average values for the two sexes differ by smaller amounts and in different directions for different traits.32 Though men, on average, are better at mentally rotating objects and maps, women are better at remembering landmarks and the positions of objects. Men are better throwers; women are more dexterous. Men are better at solving mathematical word problems, women at mathematical calculation. Women are more sensitive to sounds and smells, have better depth perception, match shapes faster, and are much better at reading facial expressions and body language. Women are better spellers, retrieve words more fluently, and have a better memory for verbal material.
