The Psychology of Boyhood and Masculinity — How Boys Are Shaped
The evidence
What the research actually shows
In Real Boys (1998), psychologist William Pollack described a 'Boy Code' — an unwritten set of rules that pushes boys toward stoicism, self-reliance, status, and the suppression of fear or sadness. Pollack argued that boys are often required to separate prematurely from tenderness and dependency, a wounding he linked to lasting emotional guardedness. The feelings, in his account, do not disappear; they go underground.
Niobe Way's Deep Secrets (2011), based on years of interviews with teenage boys, found something the stereotype misses entirely. Younger boys describe intimate, emotionally rich friendships and openly value having a best friend they can share secrets with. But as they move through adolescence, roughly between ages 15 and 18, many begin distancing themselves from that closeness for fear it will seem unmanly, and report growing loneliness. Way calls this a 'crisis of connection.'
Ronald Levant's concept of 'normative male alexithymia' proposes that many boys are socialized in ways that leave them with a reduced vocabulary for emotion — able to feel deeply but less practiced at identifying and articulating what they feel. Judy Chu's longitudinal work (When Boys Become Boys, 2014) similarly found young boys to be perceptive and relational, with those capacities dimming as they learned to perform masculinity. Across this body of research the theme is consistent: the constriction is largely taught, not innate.
The feelings do not vanish when a boy is told to toughen up; they go underground.
The mechanism
Why this happens
Boys learn masculinity partly through reward and punishment. Crying or seeking comfort is often met with 'be a man' or teasing, while toughness and independence earn approval. Peers police these norms intensely in adolescence, when fitting in can feel like survival. The lesson many boys draw is that certain feelings are unacceptable to show, so they mask them rather than share them.
Boys also model the men around them, who may themselves have limited emotional vocabulary, and on average they receive less 'emotion talk' from early caregivers than girls do. The result is not an absence of feeling but a shortage of practice at naming it — a skill gap rather than a deficit of the heart.
Masculinity is often treated as something to be earned and defended rather than simply possessed, which raises the stakes on any behavior that might read as weak. This 'precarious manhood' (Vandello and Bosson, 2013) helps explain why some boys and men overcorrect into bravado — the status feels perpetually one slip from being lost.
In practice
What this looks like in real life
A seven-year-old cries after a scraped knee and is told to 'shake it off' and toughen up. Repeated across years, the message lands quietly but firmly: pain is to be hidden, not shared.
Two thirteen-year-old best friends who once talked about everything grow awkward about that closeness by sixteen, trading heart-to-hearts for banter and gaming — not because the need for connection died, but because showing it started to feel risky.
A grown man struggles to answer 'How do you feel?' not because he feels nothing but because he was never given much practice putting the inner weather into words — a direct echo of how he was raised.
By the numbers

Myth vs. evidence
What most people get wrong about this
The biggest misconception is that boys are naturally less emotional or less relational than girls. The developmental evidence points the other way: young boys are highly attuned and form deep friendships, and it is socialization, not biology, that later narrows their expression. 'Boys will be boys' mistakes a trained response for an innate one.
People also assume the Boy Code is simply old-fashioned and gone. Elements have softened, but many of its pressures — don't be weak, don't be too close to other guys, prove yourself — persist today in schoolyards, sports teams, and online spaces, sometimes in newer forms.
Why it matters
What this means for relationships
Understanding boyhood reframes a lot of adult behavior. A partner's difficulty opening up, a friend's deflection into jokes, a man's flinch at vulnerability — these often trace back to lessons learned young, not to indifference. Meeting them with patience rather than pressure tends to reopen the door that adolescence quietly closed.
For raising boys, the implications are hopeful. Naming boys' emotions with them, keeping the language of feeling alive past early childhood, and protecting rather than mocking their friendships all help preserve the emotional fluency they start with. Boys allowed to stay connected tend to grow into men who can connect.
Typical emotional socialization (average tendencies)
A side-by-side contrast to make the distinction concrete — patterns and tendencies, not rigid rules.
| Aspect | Boys (on average) | Girls (on average) |
|---|---|---|
| Message about tears | Often discouraged — 'be tough,' 'don't cry' | More often comforted and allowed |
| Emotion talk from caregivers | Tends to receive less, with a smaller feelings vocabulary | Tends to receive more, with richer emotional labels |
| Closeness between friends | Valued young, then policed as unmanly in adolescence | More consistently encouraged and sustained |
| Route to social approval | Toughness, independence, achievement | Warmth, relationship, expressiveness |
Where it varies
The nuance
Boyhood is not one experience. Culture, family, temperament, class, and race all shape how strongly the Boy Code presses and what version of masculinity a boy is offered. Some boys grow up in homes and communities where emotional openness is modeled and welcomed, and they carry that forward without much of the constriction described here.
It is worth stating plainly that masculinity itself is not the problem — rigid, narrow masculinity is. Much of this research is qualitative and culturally specific, and it describes tendencies, not destinies. The encouraging finding is how much of what constrains boys is learned, because learned things can be taught differently.
Key takeaways
- Research suggests young boys are as emotionally expressive and relationally attuned as girls; the narrowing comes later, through socialization.
- Pollack's 'Boy Code' pressures boys toward stoicism and self-reliance, sending vulnerable feelings underground rather than erasing them.
- Niobe Way found boys treasure close friendships but often abandon that intimacy in mid-adolescence, which fuels loneliness.
- These pressures help explain adult patterns like difficulty naming feelings and reluctance to seek help.
- Because the constriction is learned, healthier masculinity can be taught — and boys vary widely by culture, family, and temperament.
Questions people ask about this
What is the 'Boy Code'?
It is William Pollack's term (Real Boys, 1998) for the unwritten rules that push boys toward stoicism, self-reliance, toughness, and hiding fear or sadness. Pollack argued these rules ask boys to suppress vulnerable feelings rather than to stop having them.
Are boys really less emotional than girls?
Research suggests not. Developmental studies find young boys are as expressive and relationally attuned as girls; the narrowing tends to come later, through socialization. Lower expression in adulthood reflects practiced masking, not lower feeling.
Why do boys' close friendships seem to fade in the teenage years?
Niobe Way's interviews found boys treasure intimate friendships early on but often pull away from that closeness in mid-adolescence, fearing it will look unmanly. Many report loneliness as a result — a pattern she calls a crisis of connection.
How does boyhood affect men later in life?
Early socialization is linked to adult patterns such as difficulty naming emotions (normative male alexithymia), a habit of showing care through action rather than words, and reluctance to seek help. These are tendencies shaped by upbringing, not fixed traits, and they can change.
Can we raise boys with a healthier masculinity?
Yes. Keeping emotion talk alive past childhood, naming feelings with boys, valuing their friendships, and modeling openness all help preserve the emotional fluency boys start with. Because the constriction is learned, a different lesson can be taught.
Is masculinity itself harmful?
No — the research points at rigid, narrow versions of masculinity as the issue, not masculinity as such. Many expressions of masculinity are healthy and life-affirming. The goal is to widen the range boys are allowed, not to erase it.
