Book summary “Woman's inhumanity to woman”: summary

Introduction

You likely know the sharp sting of betrayal by another woman, whether through workplace backstabbing, social exclusion, or malicious gossip. Society tells you that women are naturally nurturing, peaceful, and inclined toward universal sisterhood, which makes female cruelty feel like an isolated anomaly.

Phyllis Chesler argues in Woman's Inhumanity to Woman that female aggression is real, chronic, and culturally ignored. You will discover why this topic remains a feminist taboo and how female cruelty operates through indirect, psychological methods rather than physical violence.

The book explores these core questions:

• Why do women deny female aggression and cling to the myth of universal sisterhood?
• How do girls learn covert bullying and the tyranny of niceness?
• In what ways do adult women enforce patriarchal values against each other?
• What causes destructive rivalries between mothers, daughters, and sisters?

1. The Animal Within and Indirect Aggression

Men commit ninety percent of the violent crimes in our society and control most resources. These realities make male aggression highly visible and terrifying. In contrast, female aggression is chronic and behavioral. It seems unimportant because it rarely results in immediate death or severe physical injury.

Female aggression is chronic, subtle, and behavioral, relying on indirect methods like gossip and social exclusion rather than physical violence.

Male soldiers and pilots engage in mass destruction and systematic atrocities. Women are rarely viewed as violently dangerous unless their actions are deemed unnatural and pathological.

Primate and Anthropological Evidence

Primate studies reveal that female-female aggression, including infanticide and resource competition, is a fundamental organizing principle of female social life. Research on chimpanzees, lemurs, and other primates shows that females fiercely compete for dominance and resources. They sometimes engage in infanticide and cannibalism to secure advantages for their own offspring and matrilines.

A 35-year study of chimpanzees conducted by Anne Pusey, Jennifer Williams, and Jane Goodall documented female violence. More than six million years ago humans parted company from primate ancestors. Dian Fossey and Jane Goodall observed dominant chimpanzees and gorillas, such as Passion and Pom, abducting, killing, and cannibalizing the infants of lower-ranking females.

Anthropological surveys demonstrate that female-to-female aggression occurs globally across diverse human societies, most frequently targeting other women. A study by Victoria K. Burbank across 137 societies showed that women initiate physical, verbal, and indirect aggression worldwide. They primarily target co-wives, sexual rivals, and other women rather than men.

In 1870 Aymara women kicked apart the cooking stoves of their rivals. In 1964 a Kapauku woman destroyed her rival's house and uprooted her garden.

Data from Burbank show clear patterns of female conflict:

• 91 percent or 124 of the 137 societies feature women as targets of female aggression;
• 54 percent or 74 of the 137 societies feature men as targets of female aggression;
• 29 percent of societies feature verbal aggression among co-wives;
• 18 percent of societies feature physical aggression among co-wives;
• 14 percent of societies feature aggression between sisters-in-law;
• 12 percent of societies feature aggression between mothers-in-law and daughters-in-law.

The Development of Indirect Aggression

Evolutionary psychologists note that women support patriarchy by choosing alpha mates and favoring sons over daughters. Because you live within male-dominated social structures, you may depend economically and socially on male power. Women often inflict injury on female rivals, such as co-wives or daughters-in-law, to secure status.

In traditional Asian households, mothers-in-law subjected young brides and adopted daughters to severe harassment, beatings, and labor exploitation.

As children develop, aggression shifts from physical violence to verbal and ultimately to social or indirect aggression, a method heavily utilized by females. While infants and toddlers use physical aggression like hitting and biting, boys transition into physical and verbal aggression while maintaining lower levels of indirect aggression. Girls develop social intelligence earlier and rely on low-risk indirect methods like gossip, shunning, and backstabbing to avoid direct physical confrontation.

Primatologist and psychologist studies show that when a newcomer is introduced to a group of first-graders, girls engage in indirect aggression such as exclusion within four minutes. Boys take up to sixteen minutes to display indirect aggression. A 1969 study by Feshbach examined gender differences in aggression among 84 Caucasian first-graders from middle-class backgrounds in Los Angeles.

Cross-cultural research utilizing peer estimates demonstrates that girls overwhelmingly prefer indirect aggression over physical or verbal methods as they age. Because self-reports and interviews are unreliable due to subjects lying to present themselves well, researchers developed peer-estimate tools like the Direct and Indirect Aggression Scale (DIAS). Studies across multiple countries confirm that teenage girls use indirect aggression up to half the time, whereas boys use it least frequently.

An international study across Finland, Israel, Poland, and Italy by Osterman and colleagues evaluated 2,094 subjects using the DIAS inventory in 1998. The results show distinct behavioral patterns:

• 52 percent represents the proportion of the time 15-year-old girls used indirect aggressive strategies;
• 26 percent represents the proportion of the time 15-year-old and 8-year-old boys used indirect aggression;
• 23 percent represents the proportion of the time 11-year-old boys used indirect aggression.

2. Girlhood Dynamics and the Tyranny of Niceness

Pre-adolescent girls fall prey to a tyranny of niceness that forces them to suppress authentic feelings, avoid disagreement, and conform strictly to group expectations. Because you are terrified of exclusion and social alone-ness, you engage in constant self-monitoring to remain connected. This suppresses spontaneity, prevents direct conflict resolution, and forces you to censor your opinions to avoid being ostracized by your peers or cliques.

In interviews by Brown and Gilligan, third-grade girls like Jessie struggle to be nice to preserve their social world, fearing that expressing disruptive strong feelings will lead to abandonment.

Dyadic Intimacy and Gossip

Unlike boys who gain status through group hierarchy and collective achievements, girls demand strict egalitarian equality within intimate dyads and cliques. Girls' friendships are based on pairbond intimacy and small core groups. Differences in status, physical appearance, or achievements create intense tension because girls fear that a more successful friend will abandon them. Consequently, superior success or popularity often decreases your peer status rather than enhancing it.

Researchers Benenson and Bennaroch explored adolescent friendships in Montreal and found that girls cared significantly more than boys if their friends were more attractive, popular, or had more close friends.

Girls execute indirect aggression through elaborate behind-the-back storytelling designed to enlist allies in righteous indignation against a target. Rather than confronting an offender directly, you discuss your grievance in the target's absence. You carefully manage the narrative to implicate potential allies so they share equal vulnerability and guilt, ultimately forming a coalition to shun or confront the victim without appearing personally malicious.

Anthropologist Marjorie Harness Goodwin observed natural interactions among Philadelphia school children in 1990, detailing how a girl named Betty recruits Carolyn and Diane against an absent peer by framing the grievance as a collective offense.

• Discuss a grievance about another person only in that party's absence.
• Manage the presentation of past events carefully to persuade potential allies that they have also been offended.
• Wait until the recipient implicates herself before establishing a shared coalition.
• Form a two-against-one coalition based on righteous indignation to bring action against the target.

Rationalizing Cruelty as Niceness

Girls rationalize their competitive or aggressive behavior by renaming it and convincing themselves that their actions are actually intended to be nice. Because you view aggression so negatively, you employ cognitive dissociation to deny that you have acted aggressively. By framing competitive exclusions or hurtful acts as part of a social maneuver that ultimately preserves group harmony or includes others, you protect yourself from feelings of guilt and avoid altering your behavior.

Researcher Linda A. Hughes studied 11-year-old girls playing Foursquare in 1998 and found they called their competitive eliminations nice-mean, verbally apologizing to an ousted player while claiming the action was meant to be nice to someone else.

Pre-adolescent girls suppress authentic feelings and enforce strict egalitarian equality through indirect manipulation and instigation.

3. Woman's Sexism and Social Control

Women internalize misogynistic values and enforce patriarchal norms through competitor derogation, ambivalent sexism, and lethal gossip.

You often encounter women who excel in interpersonal skills and project warmth. Purdue psychologists Alice Eagly and Steven Karau found that women show social-emotional contributions like solidarity and agreement. Linguist Lynette Hirschman noted that women elaborate on each other's statements rather than arguing.

However, this capacity to inspire trust often coexists with aggression directed mainly toward other women. Victoria Burbank surveyed 137 societies and found that women targeted other women for aggression in 91 percent of them. Men were victims of women's aggression in only 54 percent of societies.

Victim Blaming and Juror Bias

You can observe how women internalize hostility and adhere to rape myths. Women frequently blame rape and sexual harassment victims, believing that women provoked the acts. This victim-blaming serves as a psychological defense mechanism so you can feel secure from similar harm.

Legal research by Lynn Hecht Schafran, studies by Gloria Cowan involving 155 American college women, and real-world trials document this pattern. In 1991, female juror Lea Haller acquitted William Kennedy Smith of rape, stating he was too charming and good-looking to resort to violence.

Anthropologist John Townsend found that professional women derogate female competitors to diminish their appeal. Female medical students described their female competition as less intelligent, and deprecated lower-status competitors as bimbos or airheads.

Peter Glick and Susan Fiske administered Ambivalent Sexism Scales across five continents in 19 countries with more than 15,000 respondents. Women in nations with the highest mean sexism scores endorsed benevolent sexism significantly more than men. Hostile sexism and benevolent sexism work together internationally to maintain traditional gender roles and elicit women's cooperation in their own subordination.

Gossip as Social Control

You might view gossip as harmless trivia, but anthropologists like David Gilmore and Max Gluckman show it functions as a lethal tool of verbal aggression. Gossip enforces traditional morality, solidifies group identity, and penalizes women who step out of line.

David Gilmore documented the story of Conchita in Spain, whose wedding was ruined and spirit broken after an envious peer, Maria, spread malicious lies about her character. These malicious social campaigns can culminate in ostracism, suicide, or honor killings.

4. The Mother-Daughter Shadow and Family Conflict

Fairy tales, psychoanalytic theory, and real-world trauma reveal that mother-daughter relationships are fraught with envy, matrophobia, and abuse.

Scholar Marina Warner notes that stories involving wicked stepmothers, witches, and competing co-wives vibrate with the insecurity and rage of women who depend on male heroes for survival and status. These traditional narratives continue to resonate in modern media and real-life disputes.

Thirty-eight-year-old Lucy faced a bitter custody and divorce battle after her husband left her for their young babysitter and suggested Lucy work at Burger King.

Mothers-in-law often experience unconscious jealousy toward daughters-in-law, viewing them as rivals who have replaced them as the primary woman in their son's life. Eighty-three-year-old Lottie blamed her daughter-in-law entirely for her son's failure to visit her alone or call without checking with his wife first. Societal overemphasis on female youth and beauty forces women into a continuous cycle of competition where younger women act as potential replacements.

Matrophobia and Maternal Envy

Sigmund Freud admitted that a daughter's early pre-Oedipal attachment to her mother is exceptionally difficult to analyze and understand. In 1931, he compared grasping this bond to discovering the Minoan-Mycenaean civilization behind Greece, noting it seemed to have suffered an inexorable repression.

Coined by Adrienne Rich and built upon Phyllis Chesler's work in 1972, matrophobia is the fear of becoming like one's mother or inheriting her powerless fate. It describes a daughter's urgent desire to be purged of her mother's bondage, unfree victimhood, and martyrdom.

Traditional mothers frequently envy and persecute their accomplished, ambitious, or creative daughters. Camille Claudel's mother viewed her sculpting career and liaison with Rodin as an affront to propriety, and her brother had her institutionalized for 30 years with her mother's full approval.

Cruelty and the Good Enough Mother

Even seemingly normal mothers can routinely subject their daughters to horrendous behaviors, including constant criticism, coldness, physical punishment, and pathologizing.

Constant criticism of a daughter's appearance and general behavior maims her spirit and conditions her to accept humiliation. The author's mother dismissed a test grade of 95 by saying she could have gotten 100 with more effort.

Olive Schreiner reported her most searing early memory was receiving a beating of 50 strokes with a bundle of quince rods from her mother at age five. Severe physical discipline administered by mothers teaches daughters to endure abuse and creates a trauma bond akin to the Stockholm Syndrome.

Mothers routinely violate adolescent and adult boundaries through intense sexual surveillance and by collaborating in paternal abuse. In 1988, 16-year-old Rose Wilson shot her mother Martha in the head after her mother refused to protect her from daily abuse and told her she could live with it.

5. Sisters, Workplace Rivalries, and Group Dynamics

Adult women replicate sibling and maternal conflicts in friendships, workplaces, and all-female groups through covert competition and scapegoating.

You unconsciously experience other women as threatening or withholding mothers, projecting past conflicts onto colleagues and friends. A New York City magazine editor-in-chief named Natalie stated that working in an all-female space is extremely dangerous because competition is unleashed and colleagues can turn from best friends into worst nightmares in a flash.

Workplace Double Binds and Betrayal

Middle-class women often view direct competition among themselves as taboo, which causes denied competition to surface in destructive ways. Economist Ivy E. Broder discovered that female academics in economics rejected female proposals for National Science Foundation funding more frequently than male economists did.

Studies of female-staffed organizations, such as Paige P. Edley's research on Nan's Interiors, show that women suppress creative dissent and money demands while treating each other like mothers, daughters, and sisters. At Nan's Interiors, employees who expressed dissent or creative independence were subjected to public humiliation in weekly meetings referred to as the hot seat or whipping post, and were eventually washed out by having new clients withheld.

Corporate consultant Judith Briles found that female executives reported substantial unethical treatment by other women driven by envy, fear of job loss, or professional threat, rather than strategic ambition. EPA official Anne became intensely jealous of her high-performing subordinate Rita Lavelle, ultimately scapegoating and framing her to save her own position, which resulted in Rita being prosecuted and jailed.

The Myth of the Happy Family in Groups

Women form all-female groups for altruism, community, and support, but these groups can also harbor intense indirect aggression, envy, and the severe punishment of non-conformists. Mary McCarthy's novel The Group portrays upper-class college women in the 1930s who coldly watch as one of their members, Kay, suffers a nervous breakdown and death following her husband's affair with another group member.

Women in groups unconsciously project their early maternal longings and fears onto the collective entity and its leaders, treating the group as either an all-loving or a vengeful mother.

Alyssa, a syndicated columnist, described belonging to a group of women who tolerated a famous, abusive woman who used everyone for errands and chores while being treated as a helpless invalid. When Alyssa withdrew, she was labeled a bad person and ostracized. Carmen, a health club manager, described how a member named Maggie managed to oust another woman named Maria by looking away whenever Maria spoke, starting simultaneous conversations, and responding only with put-downs.

You can transform these dynamics by adopting conscious psychological standards:

• Acknowledge your own human capacity for aggression, competition, envy, and cruelty.
• Develop a strong and independent mind and spirit by first loving your own self.
• Resist the illusion of instant intimacy and the assumption that a newfound intimate is a true friend or ally.
• Learn how to remain connected to women who are both different from yourself and not intimates.
• Thank another woman for every small act of kindness rather than expecting everything from her.
• Express your anger verbally, directly, and only once to the offender, and then let go of that anger.
• Refuse to listen to, repeat, or instigate female-initiated slander and gossip.

You also build resilience through direct engagement:

• Learn to compete head-on for goals without viewing a temporary loss as the end of your identity.
• Choose the strongest individuals to be on your team, recognizing that their strength works for you.
• Practice being openly and directly aggressive for your own sake and the sake of your team.

Structured educational settings help you examine unacknowledged patterns:

• Establish an educational environment led by two female leaders to discuss woman's inhumanity to woman.
• State formally that women unconsciously expect constant nurturing from all-female groups and that this expectation is irrational.
• Explain that women have internalized sexist views that lead to grudge-holding, rumor-mongering, and slander.
• Encourage women to express what they think and feel directly and openly in the here-and-now.

Conclusion

You can finally abandon the myth of universal sisterhood and stop blaming yourself for female cruelty once you recognize how indirect aggression, internalized sexism, and the shadow operate.

You must integrate these hidden dynamics to build authentic relationships and protect yourself from covert hostility. Acknowledge female power and darkness without denying your own capacity for envy or malice. You can navigate female relationships with clarity by following these practical rules:

1. Stop expecting women to be morally superior to men or naturally nurturing by default.
2. Recognize indirect aggression immediately when gossip, exclusion, or false smiles replace direct confrontation.
3. Refuse to participate in triangulated conflicts or ganging up against a designated scapegoat.
4. Establish clear boundaries with female friends, colleagues, and family members who demand emotional submission.
5. Cultivate alliances based on mutual respect, shared interests, and transparency rather than forced intimacy.
