CHAPTER 11: CONFLICT BETWEEN THE SEXES
Chapter Summary
Sexual conflict is defined as genetic conflict of interest between individual males and females. Conflict
between men and women pervades social living, from disagreements on dates to emotional distress within
marriages. Evolutionary psychology provides several key insights into why such conflicts occur and the
particular forms they take. The first insight comes from strategic interference theory, which holds that
conflict results from a person blocking or impeding another person’s successful enactment of a strategy
designed to reach a particular goal. If a woman happens to be pursuing a strategy of long-term mating and
a man is pursuing a strategy of short-term mating, each will interfere with the successful attainment of the
goal of the other’s strategies. Negative emotions such as anger, distress, and jealousy are hypothesized to
be evolved solutions that alert individuals to strategic interference.
Conflict over sexual access is one of the largest spheres of conflict between the sexes and takes many
forms. First, studies document that men consistently infer greater sexual intent than do women, especially
in response to ambiguous signals such as a smile. Second, men sometimes deceive women, notably about
their emotional involvement and long-term intentions, as a strategy for gaining short-term sexual access
to women. Some of these conflicts stem from evolved cognitive biases, as predicted by the logic of error
Another manifestation of conflict occurs in the form of sexual harassment in the workplace. Men are
overwhelmingly the perpetrators of sexual harassment, women overwhelmingly the victims. The victims
also tend to have a particular profile: They are often young, single, and physically attractive. Women tend
to get more upset about sexual harassment than do men in response to the same acts, supporting the
postulate that this negative emotion serves as a signal of strategic interference. For any particular act of
harassment, women’s upset tends to be greater if the harasser is low in status, such as a garbage collector
or a construction worker, and less if the harasser is high in status.
The coevolution of men’s strategies of sexual exploitation and women’s defenses has commanded a new
line of research and theorizing. Men who pursue sexually exploitative strategies, such as deception and
high levels of verbal pressure, appear to focus on cues to female exploitable victims. Examples include
open body posture, revealing clothing, signs of incapacitation through intoxication, and reckless behavior.
Men find these cues especially attractive in short-term mates, but not at all attractive in long-term mates.
Attraction presumably functions to motivate men to choose women displaying these cues as potential
permission and persisting in sexual advances even if they have said no. Studies show that men tend to
underestimate how upset women get about acts of sexual aggression.
One controversial issue is whether men have evolved specialized rape adaptations or whether rape is a by-
product of other mechanisms such as a male desire for short-term sex combined with a generalized
proclivity to use violence to achieve a variety of goals. The existing empirical findings from studies of
rape do not uniquely support one hypothesis or the other. The finding that rape victims tend to be young
(and hence fertile), for example, does not point to the existence of adaptations to rape, since we know that
men have evolved mate preferences for young women in consensual mating contexts. Research is
urgently needed on the underlying causes to afford paths for reducing or eliminating sexual assault. One
Recent attention has focused on women’s anti-rape defenses, such as the selection of “special friends” for
protection, the choice of mates who are large and dominant, the fear of situations that place a woman at
risk of rape, and the experience of psychological pain following sexual violence. Preliminary tests of
hypotheses about women’s anti-rape defenses are promising.
Jealous conflict defines another large category of conflict between the sexes. Evolutionary psychologists
have suggested that jealousy is an evolved solution to the problems of mate poaching and mate defection.
Men’s jealousy, compared to women’s, will focus heavily on the sexual infidelity of a partner, since
historically that would have compromised a man’s paternity certainty. Women’s jealousy, compared to
men’s, is predicted to focus more on the long-term diversion of a mate’s investment and commitment. A
large body of empirical evidence supports these predictions. The sex differences are robust across
cultures, including Brazil, Japan, Korea, Germany, Sweden, and the Netherlands. They are reasonably
robust using measures of physiological distress and highly robust using cognitive measures, such as
involuntary attention, information search, decision time, and memory for cues to sexual versus emotional
infidelity. And an fMRI study revealed different patterns of brain activation in the sexes, supporting the
hypothesized sex differences in the evolved design features of jealousy.
accrue and control resources, and men have competed with one another to attract women by acquiring
such resources. An evolutionary analysis also suggests that men cannot be united with all other men in
their desire to keep women from gaining access to these resources. Men are in competition primarily with
other men, not with women. Furthermore, men are aligned in their interests with many specific women,
such as their friends, sisters, wives, lovers, nieces, and mothers.
