Raising Boys, Reading the Research

Raising Good Men: every study behind the cards.

A fourteen-card series on how men behave under pressure, what the research says to do about it, and what the Cornell case looks like when you read it through that research. Every claim on every card is a real study. This page is where the links live, with each study's scope, its limits, and a plain-language summary. By a mother raising boys.

The Cards

The full text of all fourteen cards, in order, with the card itself under each one. Each research card links to its study below.

Card 01 of 15
“My son would never.” Statistically, he probably would.
  • In an emergency, or a perceived emergency, 10 to 15% of people stay calm and act. About 75% freeze and follow whatever cue arrives first. The rest make it worse. That is not character. That is the stress response. The next cards are what the research says about how men behave in exactly that kind of room, and how to pull them toward the few who act.
SCOPE Leach, 2004, survival psychology. A frame for the series, not a measurement of men. By a mother raising boys.
Card 1
Card 02 of 15
In an emergency, 10 to 15% of people stay calm and act. About 75% freeze and follow the first cue. 10 to 15% make it worse.
  • “Most people freeze. That is normal. So we decide now what you do, before you ever need it.”
  • “If something feels wrong, you are allowed to be the first one to say so. Someone has to be first. Let it be you.”
  • “You do not have to fix it. You have to break the silence. Say ‘this is not okay’ and leave. That is the whole job.”
SCOPE Survival psychology: responses to unfolding disasters, reviewing earlier emergency studies. Not a study of men, social pressure, or morality. A frame, not a statistic about any group.
Study and linkCard 2
Card 03 of 15
A crowd produces dangerous indifference. Across 105 studies, the more people present, the less likely any one of them was to help.
  • “A room full of people is not safety. It is a room full of people waiting for someone else to go first.”
  • “If you notice it, it is yours. Do not count heads. Count on yourself.”
  • “A group chat is a crowd. Everyone reading and nobody answering is the same as nobody there.”
SCOPE Meta-analysis of 105 effects, more than 7,700 participants, 2011. General population, not men specifically. The effect weakened in clearly dangerous emergencies, and other bystanders sometimes supported intervention.
Study and linkCard 3
Card 04 of 15
Men think other men are worse than they are. Men in these studies privately valued caring more than they believed other men did.
  • “Most of the guys agree with you. They are waiting for someone to say it first.”
  • “When someone says ‘everybody thinks that,’ ask him how he knows. Usually he does not.”
  • “You will never be the only one in the room who is uncomfortable. You might be the only one who says so.”
SCOPE Two 2018 studies: a sample of men on communal roles, and a mixed-gender workplace sample. Perceived norms diverged from private beliefs. Neither measured aggression.
Study and linkCard 4
Card 05 of 15
Men overestimate what other men want. Men in this sample thought adversarial, impersonal sex was far more typical of other men than it was.
  • “The locker room is a performance. Most of the guys in it do not want what they are claiming.”
  • “You are allowed to not want that. So are most of them.”
  • “Talking about a girl like she is a prize is a tell, not a flex. Notice who does it.”
SCOPE 497 heterosexually active men, national U.S. sample, 2020. Misperceptions differed by the men's own histories. Perceptions were measured, not behavior.
Study and linkCard 5
Card 06 of 15
One room can change what a man does. When nearby men signaled contempt for women, men in this study were less likely to step in.
  • “Pick the room before you pick the night. If the talk about girls is ugly at nine, the night is ugly at one.”
  • “The guy who interrupts that talk is the strongest one there. Be him. Back him when it is someone else.”
  • “You can leave. Leaving is a decision, and it is yours.”
SCOPE 104 heterosexual men, ages 18 to 35, one laboratory scenario, 2019. An experiment, not a population estimate.
Study and linkCard 6
Card 07 of 15
The quiet man is the most reachable. Telling men their peers approved of stepping in moved intentions most among the men least inclined to act.
  • “I know you are the one who goes quiet. Quiet is fine. Silent is not. Here is the sentence: ‘Hey. Not cool. She is wasted.’”
  • “If you step in, more of them will back you than you think. The research says so, and so do I.”
  • “You do not need to be brave. You need a sentence you have already said out loud at home.”
SCOPE 332 men, quasi-experiment, 2016. Outcomes were intentions, not observed behavior. A second program with 635 college men paired norms education with bystander training.
Study and linkCard 7
Card 08 of 15
“Be a man” is a threat, and it works. Across 123 studies, threats to manhood produced distress and self-doubt more than outward aggression.
  • “Anyone who says ‘man up’ is trying to move you. Notice it. Then decide for yourself.”
  • “A man who has to prove he is a man is being played. You do not have to take the test.”
  • “Being a man is taking care of people. That is the whole definition in this house.”
SCOPE Synthesis of 123 studies, 19,448 mostly Western heterosexual men, average effect d = 0.45 across mixed outcomes. A 2026 review rates the field's replicability as moderate.
Study and linkCard 8
Card 09 of 15
“Power over women” is a specific belief, not men being men. Of the masculine norms measured, it was among those tied to worse outcomes and barroom aggression.
  • “Wanting respect is fine. Wanting control over a girl is the one belief that ends lives. Do not carry it.”
  • “Listen to how a guy talks about women when none are around. That is who he is.”
  • “Her no is the end of the conversation. Not the start of a negotiation.”
SCOPE Meta-analysis of 78 samples, 19,453 participants, 2017, plus 322 young Australian men, 2016. Associations, not causes.
Study and linkCard 9
Card 10 of 15
Who gets called out and who gets protected. Men who wanted to do the right thing still aimed it at outsiders and protected friends and popular men.
  • “The hardest version is when it is your friend. That is the only version that counts.”
  • “Loyalty means you stop him. It does not mean you cover for him.”
  • “If a group makes you prove yourself by hurting someone, the group is the problem. Walk.”
SCOPE Ethnography of undergraduate men at one campus, 2019. A separate study followed 772 men from before college; fraternity membership was associated with later perceived peer sexual aggression.
Study and linkCard 10
Card 11 of 15
One message at 1:42 a.m. What does a good man do?
  • A civil complaint says that during an alleged assault at a Cornell fraternity house in October 2024, a message went out to the chapter’s group chat inviting others upstairs, and that people answered it. Seven men are named defendants. Everyone else in that chat is who the last nine posts were about.
SCOPE Allegations in a civil complaint. Criminal investigation reopened September 28, 2026. Two defendants deny the allegations through counsel.
Card 11
Card 12 of 15
A system is not an abstraction. It is a chain.
  • A chapter culture that selects for certain men, then teaches them more. Study 13
  • A group chat where a message inviting others upstairs was answered, not reported. Alleged
  • Friends who call out the socially weak and protect the popular. Study 15
  • A hearing that let some of the accused write essays. Alleged
  • A prosecutor who declined to charge in 2024. Reported
  • A lawsuit two years later, because every link before it held. Reported
Remove any one link and ask what happens. That is the whole argument.
Card 12
Card 13 of 15
Repeating a false claim to argue with it makes it feel truer. Prior exposure raised the perceived accuracy of false headlines even in people who knew better.
  • “When the gross take lands in the chat, do not forward it to dunk on it. Say what happened. Say it was wrong. Then name what he is doing.”
  • “The first sentence wins. Lead with what is true, not with what you are against.”
  • “You can call out the move without repeating the line: ‘That is him blaming her so nobody looks at the chat.’”
SCOPE Online and lab samples, U.S. adults; effects on perceived accuracy, not behavior. Inoculation: teaching the manipulation technique first improved recognition of it. The truth-first sequencing is a communications protocol, not a study.
Study and linkCard 13
Card 14 of 15
To raise one of the 10%, you have to be one.
  • Competent, ethical, willing to lead. Kids do not learn that from a talk. They learn it from watching a parent be the first one in a room to say that something is wrong.
  • That means calling out groupthink at your own table. In the family chat, at the game, at church, at work. When everyone is going along with something wrong, the example is the parent who says so, out loud, where the kids can see it.
  • You will not always have another option. In politics, at work, in organizations you do not run, you may not be able to stop it. You can still voice the concern. You can still remove your support. Your kids are watching whether you do.
  • Stand up against the crowd for good, where they can see it. That is the whole lesson.
Card 14
Card 15 of 15
Where are the fathers?
  • Mothers already carry the weight of raising good men. We did not ask for it. We have never been allowed to put it down.
  • The research is blunt. Boys learn what a man is from men. And men guess wrong about what other men think, until a man they respect says it out loud.
  • Every mother I know has said something about Cornell. I can count the fathers on one hand. Your son reads that silence as agreement.
  • If you do not want women to rage at you every time the system shows itself like this, be a man who is not dangerously indifferent.
  • Your silence is the dangerous indifference. Your support for predators, and for the men who seek to control and dominate women, is the dangerous indifference.

Why People 'Freeze' in an Emergency: Temporal and Cognitive Constraints on Survival Responses

Leach, 2004 · Aviation, Space, and Environmental Medicine, 75(6), 2004

Leach reviews how people respond in the first minutes of an unfolding disaster and finds the same rough split across emergencies: 10 to 15 percent remain relatively calm and keep their judgment, around 75 percent are stunned and bewildered and behave reflexively, and 10 to 15 percent show counterproductive behavior that adds to their danger. His explanation is cognitive: under sudden stress, working memory and the speed of processing a novel situation collapse, so most people do not decide at all. They follow the first cue. The series uses this openly as a frame for the social kind of emergency, where something is going wrong in a room and nobody has moved yet.

Scope  Survival psychology reviewing earlier disaster studies. Not a study of men, social pressure, or morality. A frame for the series, never a statistic about any group.

The Bystander-Effect: A Meta-Analytic Review on Bystander Intervention in Dangerous and Non-Dangerous Emergencies

Fischer et al., 2011 · Psychological Bulletin, 137(4), 2011

The bystander effect is one of the most replicated findings in social psychology: the more people present, the less likely any one of them is to help. This synthesis confirms it across 105 effects, and adds two things that matter for the series. When the danger was unambiguous, the effect shrank. And the presence of other bystanders sometimes increased helping, because they can provide physical support and a cue. A crowd can go either way. What tips it is whether one person moves first.

Scope  Meta-analysis of 105 effects and more than 7,700 participants. General population, not men specifically. The effect weakened in clearly dangerous emergencies, and other bystanders sometimes supported intervention.

Knowledge Does Not Protect Against Illusory Truth

Fazio, Brashier, Payne and Marsh, 2015 · Journal of Experimental Psychology: General, 144(5), 2015

Reading a statement twice makes it feel truer, and this held even for statements participants had the knowledge to identify as false. Familiarity does its work regardless of what you know. This is why replaying a claim in order to rebut it is not neutral: the repetition is the payload.

Prior Exposure Increases Perceived Accuracy of Fake News

Pennycook, Cannon and Rand, 2018 · Journal of Experimental Psychology: General, 147(12), 2018

A single prior exposure to a false headline raised its perceived accuracy on a later viewing. The effect survived a disputed-by-fact-checkers label, survived a week, and showed up even for headlines that clashed with the reader's politics. The reaction video that plays the clip in order to refute it is, measurably, the clip with a second audience.

Scope  Online samples of U.S. adults. Perceived accuracy of headlines, not sharing or behavior.

Psychological Inoculation Improves Resilience Against Misinformation on Social Media

Roozenbeek, van der Linden, Goldberg, Rathje and Lewandowsky, 2022 · Science Advances, 8(34), 2022

Short videos that explained a manipulation technique (emotional language, false dichotomies, scapegoating) before viewers met it improved their ability to spot that technique in new material. You do not inoculate people by showing them the virus. You describe how the virus works. That is the research behind naming the tactic instead of repeating the claim.

Scope  Large online experiments, including a YouTube field study. Outcomes were recognition of manipulation techniques and sharing intentions, not real-world belief change.

The Psychological Drivers of Misinformation Belief and Its Resistance to Correction

Ecker et al., 2022 · Nature Reviews Psychology, 1, 2022

Corrections work, partially, and the familiar false frame tends to persist after the correction has been heard. The review's practical guidance is the shape of the series' Cornell cards: lead with the fact, mention the false claim once and only if necessary, explain the technique, and repeat the fact.

Scope  A review. Synthesizes the literature; does not report a new sample.

Uncovering Pluralistic Ignorance to Change Men's Communal Self-descriptions, Attitudes, and Behavioral Intentions

Van Grootel et al., 2018 · Frontiers in Psychology, 9:1344, 2018

Men were asked what they valued and what they believed other men valued. They underestimated other men's acceptance of caring and communal roles. When the researchers corrected that misperception by showing men the real numbers, some of the men's self-descriptions, attitudes, and intentions moved. This is pluralistic ignorance: privately rejecting a norm while believing everyone else endorses it. The private belief was better than the guessed-at norm.

Scope  A sample of men on communal roles. Shows perceived norms diverging from private beliefs. Does not measure aggression.

Everybody but Me: Pluralistic Ignorance and the Masculinity Contest

Munsch et al., 2018 · Journal of Social Issues, 74(3), 2018

Workers believed their coworkers endorsed competitive masculinity norms (never showing weakness, putting work first, dog-eat-dog competition) more strongly than those coworkers actually reported endorsing them. Everybody thought everybody else believed it. The title says the whole finding.

Scope  A mixed-gender workplace sample. Supports the perception gap; does not establish that men overestimate aggression.

Social Norms: Are Sexually Aggressive Men More Likely to Misperceive Other Men's Sexual Desires and Behavior?

Casey, Masters and Beadnell, 2020 · Journal of Aggression, Maltreatment and Trauma, 29, 2020

Men rated how typical various sexual scenarios were for other men, including adversarial and impersonal ones. They overestimated how common those scenarios were and misjudged other men's preferences for them. Men with their own histories of sexual aggression misjudged peers most. The locker room, in other words, is a performance that most of the men in it do not actually want.

Scope  497 heterosexually active men, national U.S. sample. Perceptions were measured, not behavior. Misperceptions differed by the men's own histories.

Misogynistic Peers, Masculinity, and Bystander Intervention for Sexual Aggression: Is It Really Just "Locker-Room Talk?"

Leone and Parrott, 2019 · Aggressive Behavior, 45(1), 2019

Participants sat with male confederates who either talked about women with contempt or kept the conversation ambiguous, then watched a scenario heading toward sexual aggression with a chance to intervene. Misogynistic peer cues inhibited intervention, and the effect depended on how strongly a participant endorsed masculine status norms. The same man, in a different room, behaved differently. This is the experiment the series is built around.

Scope  104 heterosexual men, ages 18 to 35, one laboratory scenario. An experiment, not a population estimate. Not a universal response to a dominant man.

Do Sexual Assault Bystander Interventions Change Men's Intentions? Applying the Theory of Normative Social Behavior to Predicting Bystander Outcomes

Mabry and Turner, 2016 · Journal of Health Communication, 21(3), 2016

Men received messages about intervention. The message that worked was about peer approval, that other men approve of stepping in, and it was most effective among the men least inclined to intervene at the start. The quiet one is the most reachable one in this study. He does not need more courage. He needs to know the others will back him.

Preventing Sexual Aggression Among College Men: An Evaluation of a Social Norms and Bystander Intervention Program

Gidycz, Orchowski and Berkowitz, 2011 · Violence Against Women, 17(6), 2011

A program that paired social-norms education (correcting what men think other men believe) with bystander training reported effects on self-reported sexual aggression and on perceived peer intervention. Pairing the message with a script is what the series recommends at home, and this is why.

Scope  635 college men. A combined program, so norms correction cannot be isolated as the single cause.

Precarious Manhood

Vandello et al., 2008 · Journal of Personality and Social Psychology, 95(6), 2008

Manhood, in many cultures, is a status that has to be earned and can be lost, which means it can be threatened. These early experiments linked threats to manhood with distress and aggressive thoughts. The theory is the basis for the next two sources.

Masculinity Threat in Heterosexual Men: A Comprehensive Meta-Analysis of Experimental Research with Recommendations for Future Theory Building and Research Practice

Lorenz et al., 2026 · Personality and Social Psychology Review, 2026

The largest synthesis of masculinity-threat experiments to date, with an average effect of d = 0.45. The strongest responses were negative emotion and a drop in self-perceived masculinity, not outward aggression, and reactions weakened after the initial response. Shame comes first. That is the finding the series puts on the card.

Scope  Synthesis of 123 studies and 19,448 predominantly heterosexual, mainly Western men. The average effect pools emotional, cognitive, and behavioral outcomes. It does not mean 45 percent of men become aggressive.

Meta-Analyses of the Relationship Between Conformity to Masculine Norms and Mental Health-Related Outcomes

Wong et al., 2017 · Journal of Counseling Psychology, 64(1), 2017

Researchers measure masculinity in pieces: winning, emotional control, risk taking, violence, self-reliance, playboy behavior, power over women, and more. Three of those pieces were consistently associated with worse mental-health outcomes: self-reliance, playboy behavior, and power over women. The series uses this to make one point: you do not have to fight being a man. You have to name one belief.

Scope  78 samples, 19,453 participants. Associations, not causes. Masculinity is examined by dimension, not as one personality type.

Barroom Aggression Among Australian Men: Associations With Heavy Episodic Drinking, Conformity to Masculine Norms, and Personal and Perceived Peer Approval of Barroom Aggression

Miller et al., 2016 · Journal of Studies on Alcohol and Drugs, 77(3), 2016

Heavy episodic drinking, personal approval of aggression, and perceived male peer approval were all associated with verbal and physical aggression in bars. Power-over-women norms raised the risk in the model; emotional control and heterosexual self-presentation norms were associated with lower risk. Perceived peer approval shows up again as the lever.

Friends, Strangers, and Bystanders: Informal Practices of Sexual Assault Intervention

Wamboldt et al., 2019 · Global Public Health, 14(1), 2019

Ethnographic research on how undergraduate men actually intervene. Many wanted to act responsibly, but their interventions targeted socially vulnerable or distant men while protecting friends and popular men. The authors argue that informal intervention can reproduce existing hierarchies. The hardest version, calling out a friend, is the one that counts, and this is the study that says why.

Selection and Socialization Accounts of the Relation Between Fraternity Membership and Sexual Aggression

Treat et al., 2021 · Psychology of Addictive Behaviors, 35(3), 2021

Precollege drinking and sociosexual attitudes predicted who joined a fraternity (selection). Membership was then associated with later binge drinking and perceived peer sexual aggression, and prospectively correlated with sexual aggression after accounting for the measured selection factors (socialization). A group chooses certain men, then teaches them more. This is link one in the chain card.

Two Ways to the Top: Evidence That Dominance and Prestige Are Distinct yet Viable Avenues to Social Rank and Influence

Dominance (influence through intimidation) and prestige (respect freely granted for competence and contribution) are distinct routes to influence, and both work. Prestigious people were better liked.

The Cornell Case

Reporting, not research. The series cites studies for mechanisms and cites reporting for the case. The two never substitute for each other.

What is alleged and what is reported. A civil complaint filed in mid-September 2026 names seven members of Cornell's Chi Phi chapter and alleges that during an assault in October 2024 a message went out to the chapter's group chat inviting others upstairs, and that people answered it. Two of the named men have denied the allegations through their lawyers; one has acknowledged sending a message but denies any sexual contact. Cornell says its 2024 hearing expelled two members and closed the chapter; the complaint alleges other members were allowed to write essays, a characterization Cornell disputes. The Tompkins County District Attorney declined charges in 2024 and on September 28, 2026 reopened the case for grand jury review. The New York Attorney General's office is reviewing the university's response. Nothing on these cards names any individual or states what any individual did. Social pressure explains conduct. It does not excuse it.

Where are the fathers?

Mothers already carry the weight of raising good men. We did not ask for it. We have never been allowed to put it down.

The research is blunt. Boys learn what a man is from men. And men guess wrong about what other men think, until a man they respect says it out loud.

Every mother I know has said something about Cornell. I can count the fathers on one hand. Your son reads that silence as agreement.

If you do not want women to rage at you every time the system shows itself like this, be a man who is not dangerously indifferent. Your silence is the dangerous indifference. Your support for predators, and for the men who seek to control and dominate women, is the dangerous indifference.

To raise one of the 10%, you have to be one.

Competent, ethical, willing to lead. Kids do not learn that from a talk. They learn it from watching a parent be the first one in a room to say that something is wrong. That means calling out groupthink at your own table. When everyone is going along with something wrong, the example is the parent who says so, out loud, where the kids can see it.

You will not always have another option. In politics, at work, in organizations you do not run, you may not be able to stop it. You can still voice the concern. You can still remove your support. Your kids are watching whether you do.
