Most important, the book focuses in equal part on the pain of the victims. (Its draft title was Why Men Rape, Why Women Suffer.) Thornhill and Palmer explain in Darwinian terms why females throughout the animal kingdom resist being forced into sex, and argue that the agony that rape victims feel is deeply rooted in women’s nature. Rape subverts female choice, the core of the ubiquitous mechanism of sexual selection. By choosing the male and the circumstances for sex, a female can maximize the chances that her offspring will be fathered by a male with good genes, a willingness and ability to share the responsibility of rearing the offspring, or both. As John Tooby and Leda Cosmides have put it, this ultimate (evolutionary) calculus explains why women evolved “to exert control over their own sexuality, over the terms of their relationships, and over the choice of which men are to be the fathers of their children.” They resist being raped, and they suffer when their resistance fails, because “control over their sexual choices and relationships was wrested from them.”90

  Thornhill and Palmer’s theory reinforces many points of an equity-feminist analysis. It predicts that from the woman’s point of view, rape and consensual sex are completely different. It affirms that women’s repugnance toward rape is not a symptom of neurotic repression, nor is it a social construct that could easily be the reverse in a different culture. It predicts that the suffering caused by rape is deeper than the suffering caused by other physical traumas or body violations. That justifies our working harder to prevent rape, and punishing the perpetrators more severely, than we do for other kinds of assault. Compare this analysis with the dubious claim by two gender feminists that an aversion to rape has to be pounded into women by every social influence they can think of:

  Female fear… [results] not only from women’s personal backgrounds but from what women as a group have imbibed from history, religion, culture, social institutions, and everyday social interactions. Learned early in life, female fear is continually reinforced by such social institutions as the school, the church, the law, and the press. Much is also learned from parents, siblings, teachers, and friends.91

  But despite the congeniality of their analysis to women’s interests, Thornhill and Palmer had broken a taboo, and the response was familiar: there were demonstrations, disruptions of lectures, and invective that would curdle your hair, as the popular malaprop has it. “Latest nauseating scientific theory” was a typical reaction, and radical scientists applied their usual standards of accuracy to denounce it. Hilary Rose, discussing a presentation of the theory by another biologist, wrote, “The sociobiologist David Barash’s appeal in defense of his misogynist claims that men are naturally predisposed to rape, ‘If Nature is sexist don’t blame her sons,’ can no longer plug into the old deference to science as the view from nowhere.”92 Barash, of course, had said no such thing; he had referred to rapists as criminals who should be punished. The science writer Margaret Wertheim began her review of Thornhill and Palmer’s book by calling attention to a recent epidemic of rape in South Africa.93 Pitting the theory that rape is “a byproduct of social conditioning and chaos” against the theory that rape has evolutionary and genetic origins, she sarcastically wrote that if the latter were true, “South Africa must be a hothouse for such genes.” Two slurs for the price of one: the statement puts Thornhill and Palmer on the simplistic side of a false dichotomy (in fact, they devote many pages to the social conditions fostering rape) and slips in the innuendo that their theory is racist, too. The psychologist Geoffrey Miller, in his own mixed review of the book, diagnosed the popular reaction:

  The Natural History of Rape has already suffered the worst possible fate for a popular science book. Like The Descent of Man and The Bell Curve, it has become an ideological touchstone. People who wish to demonstrate their sympathy for rape victims and women in general have already learned that they must dismiss this book as sexist, reactionary pseudo-science. News stories that treat the book as a symptom of chauvinist cultural decay have greatly outnumbered reviews that assess it as science. Viewed sociologically, turning books into ideological touchstones can be useful. People can efficiently sort themselves out into like-minded cliques without bothering to read or think. However, there can be more to human discourse than ideological self-advertisement.94

  It’s unfortunate that Thornhill and Palmer themselves set up a dichotomy between the theory that rape is an adaptation (a specifically selected sexual strategy) and the theory that it is a by-product (a consequence of using violence in general), because it diverted attention from the more basic claim that rape has something to do with sex. I think their dichotomy is drawn too sharply. Male sexuality may have evolved in a world in which women were more discriminating than men about partners and occasions for sex. That would have led men to treat female reluctance as an obstacle to be overcome. (Another way to put it is that one can imagine a species in which the male could become sexually interested only if he detected reciprocal signs of interest on the part of the female, but that humans do not appear to be such a species.) How the woman’s reluctance is overcome depends on the rest of the man’s psychology and on his assessment of the circumstances. His usual tactics may include being kind, persuading the woman of his good intentions, and offering the proverbial bottle of wine, but may become increasingly coercive as certain risk factors are multiplied in: the man is a psychopath (hence insensitive to the suffering of others), an outcast (hence immune to ostracism), a loser (with no other means to get sex), or a soldier or ethnic rioter who considers an enemy subhuman and thinks he can get away with it. Certainly most men in ordinary circumstances do not harbor a desire to rape. According to surveys, violent rape is unusual in pornography and sexual fantasies, and according to laboratory studies of men’s sexual arousal, depictions of actual violence toward a woman or signs of her pain and humiliation are a turnoff.95

  What about the more basic question of whether the motives of rapists include sex? The gender-feminist argument that they do not points to the rapists who target older, infertile women, those who suffer from sexual dysfunction during the rape, those who coerce nonreproductive sexual acts, and those who use a condom. The argument is unconvincing for two reasons. First, these examples make up a minority of rapes, so the argument could be turned around to show that most rapes do have a sexual motive. And all these phenomena occur with consensual sex, too, so the argument leads to the absurdity that sex itself has nothing to do with sex. And date rape is a particularly problematic case for the not-sex theory. Most people agree that women have the right to say no at any point during sexual activity, and that if the man persists he is a rapist—but should we also believe that his motive has instantaneously changed from wanting sex to oppressing women?

  On the other side there is an impressive body of evidence (reviewed more thoroughly by the legal scholar Owen Jones than by Thornhill and Palmer) that the motives for rape overlap with the motives for sex:96

  • Coerced copulation is widespread among species in the animal kingdom, suggesting that it is not selected against and may sometimes be selected for. It is found in many species of insects, birds, and mammals, including our relatives the orangutans, gorillas, and chimpanzees.

  • Rape is found in all human societies.

  • Rapists generally apply as much force as is needed to coerce the victim into sex. They rarely inflict a serious or fatal injury, which would preclude conception and birth. Only 4 percent of rape victims sustain serious injuries, and fewer than one in five hundred is murdered.

  • Victims of rape are mostly in the peak reproductive years for women, between thirteen and thirty-five, with a mean in most data sets of twenty-four. Though many rape victims are classified as children (under the age of sixteen), most of these are adolescents, with a median age of fourteen. The age distribution is very different from that of victims of other violent crimes, and is the opposite of what would happen if rape victims were picked for their physical vulnerability or by their likelihood of holding positions of power.

/>   • Victims of rape are more traumatized when the rape can result in a conception. It is most psychologically painful for women in their fertile years, and for victims of forced intercourse as opposed to other forms of rape.

  • Rapists are not demographically representative of the male gender. They are overwhelmingly young men, the age of the most intense sexual competitiveness. The young males who allegedly have been “socialized” to rape mysteriously lose that socialization as they get older.

  • Though most rapes do not result in conception, many do. About 5 percent of rape victims of reproductive age become pregnant, resulting in more than 32,000 rape-related pregnancies in the United States each year. (That is why abortion in the case of rape is a significant issue.) The proportion would have been even higher in prehistory, when women did not use long-term contraception.97 Brownmiller wrote that biological theories of rape are “fanciful” because “in terms of reproductive strategy, the hit or miss ejaculations of a single-strike rapist are a form of Russian roulette compared to ongoing consensual mating.”98 But ongoing consensual mating is not an option for every male, and dispositions that resulted in hit-or-miss sex could be evolutionarily more successful than dispositions that resulted in no sex at all. Natural selection can operate effectively with small reproductive advantages, as little as 1 percent.

  THE PAYOFF FOR a reality-based understanding of rape is the hope of reducing or eliminating it. Given the theories on the table, the possible sites for levers of influence include violence, sexist attitudes, and sexual desire.

  Everyone agrees that rape is a crime of violence. Probably the biggest amplifier of rape is lawlessness. The rape and abduction of women is often a goal of raiding in non-state societies, and rape is common in wars between states and riots between ethnic groups. In peacetime, the rates of rape tend to track rates of other violent crime. In the United States, for example, the rate of forcible rape went up in the 1960s and down in the 1990s, together with the rates of other violent crimes.99 Gender feminists blame violence against women on civilization and social institutions, but this is exactly backwards. Violence against women flourishes in societies that are outside the reach of civilization, and erupts whenever civilization breaks down.

  Though I know of no quantitative studies, the targeting of sexist attitudes does not seem to be a particularly promising avenue for reducing rape, though of course it is desirable for other reasons. Countries with far more rigid gender roles than the United States, such as Japan, have far lower rates of rape, and within the United States the sexist 1950s were far safer for women than the more liberated 1970s and 1980s. If anything, the correlation might go in the opposite direction. As women gain greater freedom of movement because they are independent of men, they will more often find themselves in dangerous situations.

  What about measures that focus on the sexual components of rape? Thornhill and Palmer suggested that teenage boys be forced to take a rape-prevention course as a condition for obtaining a driver’s license, and that women should be reminded that dressing in a sexually attractive way may increase their risk of being raped. These untested prescriptions are an excellent illustration of why scientists should stay out of the policy business, but they don’t deserve the outrage that followed. Mary Koss, described as an authority on rape, said, “The thinking is absolutely unacceptable in a democratic society.” (Note the psychology of taboo—not only is their suggestion wrong, but merely thinking it is “absolutely unacceptable.”) Koss continues, “Because rape is a gendered crime, such recommendations harm equality. They infringe more on women’s liberties than men’s.”100

  One can understand the repugnance at any suggestion that an attractively dressed woman excites an irresistible impulse to rape, or that culpability in any crime should be shifted from the perpetrator to the victim. But Thornhill and Palmer said neither of those things. They were offering a recommendation based on prudence, not an assignment of blame based on justice. Of course women have a right to dress in any way they please, but the issue is not what women have the right to do in a perfect world but how they can maximize their safety in this world. The suggestion that women in dangerous situations be mindful of reactions they may be eliciting or signals they may inadvertently be sending is just common sense, and it’s hard to believe any grownup would think otherwise—unless she has been indoctrinated by the standard rape-prevention programs that tell women that “sexual assault is not an act of sexual gratification” and that “appearance and attractiveness are not relevant.”101 Equity feminists have called attention to the irresponsibility of such advice, in terms far harsher than anything by Thornhill and Palmer. Paglia, for example, wrote:

  For a decade, feminists have drilled their disciples to say, “Rape is a crime of violence but not sex.” This sugar-coated Shirley Temple nonsense has exposed young women to disaster. Misled by feminism, they do not expect rape from the nice boys from good homes who sit next to them in class….

  These girls say, “Well, I should be able to get drunk at a fraternity party and go upstairs to a guy’s room without anything happening.” And I say, “Oh, really? And when you drive your car to New York City, do you leave your keys on the hood?” My point is that if your car is stolen after you do something like that, yes, the police should pursue the thief and he should be punished. But at the same time, the police—and I—have the right to say to you, “You stupid idiot, what the hell were you thinking?”102

  Similarly, McElroy points out the illogic of arguments like Koss’s that women should not be given practical advice that “infringes more on women’s liberties than men’s”:

  The fact that women are vulnerable to attack means we cannot have it all. We cannot walk at night across an unlit campus or down a back alley, without incurring real danger. These are things every woman should be able to do, but “shoulds” belong in a Utopian world. They belong in a world where you drop your wallet in a crowd and have it returned, complete with credit cards and cash. A world in which unlocked Porsches are parked in the inner city. And children can be left unattended in the park. This is not the reality that confronts and confines us.103

  The flight from reality of the rape-is-not-sex doctrine warps not just advice to women but policies for deterring rapists. Some prison systems put sex offenders in group therapy and psychodrama sessions designed to uproot experiences of childhood abuse. The goal is to convince the offenders that aggression against women is a way of acting out anger at their mothers, fathers, and society. (A sympathetic story in the Boston Globe concedes that “there is no way to know what the success rate of [the] therapy is.”)104 Another program reeducates batterers and rapists with “pro-feminist therapy” consisting of lectures on patriarchy, heterosexism, and the connections between domestic violence and racial oppression. In an article entitled “The Patriarchy Made Me Do It,” the psychiatrist Sally Satel comments, “While it’s tempting to conclude that perhaps pro-feminist ‘therapy’ is just what a violent man deserves, the tragic fact is that truly victimized women are put in even more danger when their husbands undergo a worthless treatment.”105 Savvy offenders who learn to mouth the right psychobabble or feminist slogans can be seen as successfully treated, which can win them earlier release and the opportunity to prey on women anew.

  In his thoughtful review, Jones explores how the legal issues surrounding rape can be clarified by a more sophisticated understanding that does not rule the sexual component out of bounds. One example is “chemical castration,” voluntary injections of the drug Depo-Provera, which inhibits the release of androgens and reduces the offender’s sex drive. It is sometimes given to offenders who are morbidly obsessed with sex and compulsively commit crimes such as rape, indecent exposure, and child abuse. Chemical castration can cut recidivism rates dramatically—in one study, from 46 percent to 3 percent. Use of the drug certainly raises serious constitutional issues about privacy and punishment, which biology alone cannot decide. But the issues become cloudier, not clearer, when c
ommentators declare a priori that “castration will not work because rape is not a crime about sex, but rather a crime about power and violence.”

  Jones is not advocating chemical castration (and neither am I). He is asking people to look at all the options for reducing rape and to evaluate them carefully and with an open mind. Anyone who is incensed by the very idea of mentioning rape and sex in the same breath should read the numbers again. If a policy is rejected out of hand that can reduce rape by a factor of fifteen, then many women will be raped who otherwise might not have been. People may have to decide which they value more, an ideology that claims to advance the interests of the female gender or what actually happens in the world to real women.

  DESPITE ALL THE steam coming out of people’s ears in the modern debate on the sexes, there are wide expanses of common ground. No one wants to accept sex discrimination or rape. No one wants to turn back the clock and empty the universities and professions of women, even if that were possible. No reasonable person can deny that the advances in the freedom of women during the past century are an incalculable enrichment of the human condition.
