Men and Women Can't Be Friends — and Pretending Otherwise Is Costing Women Everything
A neuroscientist on why opposite-sex friendship is biologically impossible — and the lie women were raised to believe, and who actually profits from it
I. The Disappearing Act
Los Angeles, California 2009. Cruising around college campus in my 1989 Silverado Chevy truck, me and my boys. They were all huge college football players and not a single one of them had a car, so I was de facto their beer-run-driver, but I didn’t mind so much as they kept me fed with tacos as payment and the reassurance that ‘no, my body was perfect and I would not get fat from eating too many tacos.’
Me and the boys. We were thick as thieves. Or so I thought.
It ended up that we were actually as thin as used dental floss.
From one day to the next, those boys evaporated.
The trigger you ask?
It arrived plainly and without ceremony: I got a boyfriend.
Within days, the men who had texted me through the night, who had memorized my midnight taco order, who had pulled all-nighters in the library beside me — those men receded like a tide on a new moon.
Gone. Quiet. Unreachable. I'd see them across campus and they'd lift a hand like a man waving at a dental hygienist he was hoping he didn't have to make conversation with.
Perhaps I had become busy. Perhaps football season got really busy. Perhaps a great many things, because the alternative required a sentence I had not yet found the understanding of men to articulate.
The articulation would be: they were never my friends.
II. Susanna and the Elders
One of the oldest stories of the fake male friend is three thousand years old, and it is buried in the Book of Daniel.
Susanna was a beautiful, devout, married woman in Babylon, the wife of a wealthy and respected man named Joakim.1 Her house was the gathering place of the community — and two of its most frequent guests were the town's elders, men appointed as judges, men trusted so completely that disputes of life and death were settled under Joakim's roof.2
These two men were not strangers. They were friends of the house. They ate at the table. They were greeted warmly. They were, by every social measure available, safe.
And every day, as Susanna walked in her private garden, the two elders watched her. Separately, secretly, each nursing the same hidden hunger — until the day they discovered one another in the act of lurking and confessed their mutual desire.3 They hatched a plan. They hid in the garden, waited until she was alone, and confronted her: lie with us, or we will testify that we caught you committing adultery with a young man under a tree.
She refused.
Understand what her refusal cost. Adultery was a capital crime; the testimony of two male elders was nearly impossible to overturn. To refuse them was, very likely, to choose death.4 Susanna chose it anyway: “I choose not to do it; I will fall into your hands, rather than sin in the sight of the Lord.”
And here is the part I want you to feel in your sternum. The moment she said no, the friends became prosecutors. The same men who had broken bread at her husband's table seized her, laid their hands on her head before the whole assembly, and testified that she was a whore. Their “friendly” warmth curdled into vengeance in the space of a single refusal.
They were never her friends. They were predators waiting on a technicality — and the technicality was her consent.
This is the tell. A man who turns to rage the instant you decline him was never your friend; he was an investor whose position just went bad. The fury is not heartbreak. The fury is a creditor discovering the debt will not be paid. He put in the years, the favors, the patient listening — the ‘friendship’ — as a deposit. Your refusal is the bank telling him the account was never his.
And note how they came at her: not openly, not honestly, but covertly, with a threat. The approach is the confession – a confident man who actually respected Susanna would’ve stated his desire plainly, accepted her answer, and left with his dignity. Unable to bear an honest rejection, the men engineered a trap instead. Cowardice and entitlement are the same animal wearing two coats.
Three thousand years later, women are still surrounded by “male-friends” in the garden — men who present as friends of the house, who watch and wait and call it devotion, and who reveal what they always were the moment the answer is no.
We have simply stopped calling them what they are.
III. The Roll of Condoms
A few years after my collegemates’ disappearance, on the campaign trail, Mitch, a man I considered a close friend, flew across the country to spend a weekend with me while I traversed America visiting 17 national parks.
We were headed into the wilderness for three days — no town, no plumbing, no occasion on earth for either of us to require a particular kind of latex object.
Mitch set his backpack down on the floor of my tent. And out tumbled something. He scrambled for it. Too late.
There it was. A long pre-perforated tail of unopened condoms, unrolled across my sleeping bag, gleaming up at me with the polite humiliation of an accidentally exposed lie.
I did not ask. He did not explain. Some questions answer themselves so thoroughly that asking them would be overkill.
But let me make it painfully obvious, for the woman in the back row still with her arms crossed still thinking men can be friends with women: this man flew across the country, brought the whole roll, and believed sex with me was on the menu. We had never kissed. We had never flirted. I had never given him a syllable of suggestion that he was anything other than a guy I liked talking to about books.
In fact, he was so optimistic about his odds that he'd brought the whole, long roll.
IV. What the Science Actually Says About How Men Experience Women
I hold a degree in cognitive neuroscience from Occidental College, which means I have spent a meaningful portion of my adult life translating between two languages:
the one women speak about what they feel,
and the one science speaks about why we feel it.
Here is what the science says. Brace yourself.
In the year 2000, the evolutionary psychologists April Bleske-Rechek and David Buss published a landmark study with the disarmingly plain title Can Men and Women Be Just Friends?7 Across multiple samples of opposite-sex friend pairs, the men consistently rated sexual access and potential romance as primary benefits of the friendship. The women, just as consistently, did not. The asymmetry held across age, across relationship status, across attractiveness, and — this is the part I'd like you to read twice — regardless of whether the friendship was reciprocated.
A 2012 replication confirmed the pattern. Men, even when objectively committed to other partners, reported attraction to their female friends as a desirable feature of the friendship. Women overwhelmingly did not.
Read that again.
It was not a bug in the friendship. It was a feature.
In 1982, the psychologist Antonia Abbey at Wayne State University ran what is now considered the foundational study on what we now call the Sexual Misperception Bias — the cross-cultural, eerily consistent tendency of men to interpret a woman's friendliness as sexual interest.8 Forty years of replication have only strengthened her conclusion. Men, in the aggregate, decode warmth as wanting.
She smiled at me. She wants me.
She laughed at my joke. She wants me.
She remembered my coffee order. She is in love with me.
Do you remember that scene from Super Bad when Seth excitedly misinterprets Jules’s asking him to buy alcohol for her party with “She wants to f*ck me. She wants my d*ck in and around her mouth.” Watch for yourself.
This is not a personality flaw of a few unlucky individuals. It is, in the language of biology, a feature of the male species.
In 2024, a placebo-controlled study published in Frontiers in Psychology administered either eleven milligrams of exogenous testosterone or a placebo to 190 heterosexual men. Each man was then sent into a room with a friendly female confederate. The testosterone-treated men — particularly those who already considered themselves attractive — systematically reinterpreted her ordinary affiliative behavior as sexual interest.9
The placebo group did not.
The hormone did not invent the bias. It potentiated one that was already present.
And — this is the part that should make every woman currently lunching with a male coworker quietly close her laptop — the man does not even need to actually be attractive. He merely needs to consider himself attractive. The misperception runs on his self-concept, not on objective reality.
This is not a moral indictment of men. This is a wiring diagram.
V. The Deeper Wiring: How Men Actually Bond
The wiring diagram is real because the underlying neurochemistry is real.
Now, the deeper layer. Because what I've shown you so far is just the perceptual machinery. The pair-bonding machinery is a different room of this house entirely.
The neuropeptide arginine vasopressin (AVP) — first identified as the pair-bonding hormone in male prairie voles by C. Sue Carter and Larry Young at Emory10 — has since been shown to affect human male pair-bonding behavior at the genetic level. The reason traces back, in large part, to a single neurochemical pathway in the male brain.
In 2008, a study published in PNAS by Hasse Walum and colleagues found the same machinery in humans. A polymorphism in the AVPR1A gene — the gene encoding the V1a vasopressin receptor — predicts whether men form stable pair bonds, how their wives rate marital quality, and the probability of marital crisis.11 A variant in one gene. That is all that stands between the husband who shows up and the husband who disappears.
Men do not bond the way women bond.
They bond through a specific neurochemical pathway — one that activates during acts of providing for, protecting, and being appreciated by a specific woman. The bond is built by the behavior, not before it. Which is, incidentally, why all the women trying to logic a man into loving them are wasting calories he isn't even spending.
Here is what this means for the friend question. When a man is in a room with a woman he finds attractive, his neurochemistry does not allow him to be neutral. He may behave with restraint. He may be a good man. He may genuinely respect you. He may have a wife and a baby and a yoga-healthy-masculinity-boundary-yada-yada-yah practice.
But he is not having the same internal experience you are.
He is not, in any biologically meaningful sense, just your friend. The neurochemistry will not allow it. He may have lashed himself to the mast like Odysseus passing the sirens, but the song is still playing.
VI. The Empathy Move
This brings us to the move most women refuse to make.
The empathy move.
Women who deny the science of male attraction are not being open-minded. They are committing the cardinal error of empathy:
The assumption that everyone else lives inside their nervous system.
He does not live inside your nervous system. He lives inside his. To insist otherwise is not ‘giving the benefit of the doubt’ to him — it is a willful misreading of his actual experience. It is the same well-intentioned mistake the second-wave feminists made when they argued men and women are essentially the same, just differently socialized. They were trying to fight for our equality. They ended up obscuring our distinctness, and a generation of women has paid for the confusion.
We are equal. We are not the same. The male nervous system is a different appliance, and pretending otherwise is how you end up confused about why your “best friend” brought condoms to the woods.
VII. The Many Ways Male Friends Drain You (yes, even the “good” guys)
Here is the second thing women miss. More invisible than the first. Quietly more expensive.
Being a status symbol is not the only way a man unconsciously uses you. There are many ways to energy-vampire a woman. Even a man with no current interest in sleeping with you will use you as his free therapist — pouring in his anxieties, his work drama, his last breakup, walking away lighter while you walk away heavier, having metabolized feelings that were never yours to hold.
And now I already hear you: “But it goes both ways — I use him for guy advice too.” It doesn’t, and you shouldn’t. If he is your friend, you would never date him — which means, by your own assessment, he is not in the league you are fishing in.
Why would you take advice from a guppy on how to catch a shark?
He has no insight that will help you. He has only proximity to you, and a quiet interest in keeping the more impressive sharks out of the water.
* * *
Now, the status receipt. Men do not only want to sleep with you. They want to be seen with you. Even a man with no intention of ever asking you out, even a man whose admiration is purely aesthetic, accrues social capital from your proximity. You are, simply by standing near him, a referendum on his value to other men.
Anthropologists have a term for this: mate quality signaling, the deployment of an associated partner's perceived value as proof of one's own.12 You are not paranoid for noticing it. You are accurate.
* * *
Three exhibits from my own life, offered without embellishment.
William, high school prom. Told the class we had kissed. We had not.
A surfer, college freshman year. Told his friends we had hooked up. Our hands had never even touched.
A Dutch expat in Bali. Told mutuals, in passing conversation, that he had dated “a polo girl, an author.” He had done neither. We had met twice.
Each gained something — a sliver of status, a story to tell — by reporting a connection with me that did not exist. They were not lying about me. I was the prop.
* * *
There is an instagram reel I think about often.
A male friend takes his female friend to a famously expensive restaurant. He frowns as she sits down. Why aren't you wearing all your beautiful jewelry? he asks.
She looks at him, perfectly composed, and answers:
I am wearing all the jewelry you bought me.
She had understood, with a clarity her male friend had never managed, what the jewelry was for. The jewelry was not for her. The jewelry was a press release. The jewelry was a sandwich board hung on her body so other men would assume his salary could afford her.
Men live inside a hierarchical understanding of the world. They know their position in the pyramid relative to the resources — including access to women — that the men around them have or do not have, and they place themselves accordingly. Every interaction is, at some level, a status calculation.
Though women are more circular, community-based rather than hierarchical like men, we still live inside a patriarchal society that maintains the hierarchy as the operating structure — and for as long as it does, men will advertently or inadvertently use women to get to the next higher rung.
You are always either the jewelry (for him, signaling his success) — or the woman who knows what the jewelry is for. There is no third option.
VIII. “But He Doesn’t See Me That Way, He’s Not Attracted to Me”
And what about the friend who is genuinely not attracted to you — the one with a wife, the one who calls you a sister? Surely he is fine.
A man who is not attracted to you is a man who, by definition, is comparing you to other women and finding you lacking. To spend significant time in his presence is to install, inside the weekly emotional rotation of your life, a quiet ongoing referendum on your insufficiency. The ‘I’m not pretty enough’ referendum is invisible. The nervous system feels the verdict anyway.
Decades of research on social comparison theory, beginning with Leon Festinger's foundational 1954 paper,13 establishes two things relevant here: women in particular calibrate self-concept through proximal social feedback, and prolonged exposure to subtle negative appraisal degrades self-esteem even when the appraisal is never spoken aloud.14
A man who finds you unattractive is, simply by remaining in your orbit, conducting a daily microdose of disqualification.
You will not feel it as a wound. You will feel it as a low ambient hum — one you cannot quite trace, located somewhere behind your sternum, that whispers something about you needs improving. You will not connect it to him, because his face is friendly and his behavior is correct and his presence has been the wallpaper of your Tuesdays for years.
You may not feel it at all. You may simply look in the mirror and fail to see how beautiful you actually are. The hum will have done its work without ever announcing itself.
IX. The Nightlight
Whether he wants you romantically or merely wants to enjoy your company at lunch, the cost is the same. He occupies space the right man cannot.
I have come to think of the male friend as a nightlight.
A small, dim, electric pacifier you have plugged into the outlet of your life. He gives you just enough warmth to convince yourself you do not need the proper lamp. He occupies the socket. He costs you the room you would otherwise have made for the love you actually want.
You did not buy a nightlight because you preferred a nightlight.
You bought it because you were afraid of the dark, and the lamp had not yet arrived.
The trouble is that the lamp cannot arrive while the nightlight is still plugged in.
That male “friend” you share an office or house with. That male coworker you eat lunch with every other day. That hometown buddy you grab drinks with every time you're in town. He is the nightlight. He is filling the small emotional needs that would otherwise create the hunger that drives you out into the world to encounter the man who is actually meant for you. He is solving the problem just enough that you cannot feel the problem clearly enough to fix it.
There is nowhere for the lamp to plug in. Whether that’s your husband meeting your emotional needs or a boyfriend who brings you to nice dinners with flowers.
X. For the Non-Nuance Nellys
Before the comments arrive, let me preempt them. (Not that I believe this will change the minds of people who do not want their minds changed. Even when confronted with the research. Even when the research is the only argument they did not bring to the table.)
I am not saying you cannot speak to men.
I am not saying you cannot have male acquaintances.
I am not saying every emotional need must be met by a single romantic partner. (That would be exhausting and, frankly, theologically suspect — even Aristotle in the Nicomachean Ethics distinguished three kinds of friendship, and conceded that only one of them — the friendship of virtue — can ever be fully reciprocated within a single bond.)18
What I am saying is this.
If you are pursuing a long-term heterosexual relationship — with your current partner or one you haven’t met yet — you must become a careful steward of your own energy, attention, and status.
Men are always harvesting it. Whether you consent to the harvest or not.
The work is not to seal yourself off from the male world. The work is to stop pretending the male world operates on the same hormonal grammar as yours.
They do not feel what you feel. They cannot. The wiring forbids it.
XI. The Polite Pruning: How to Detach a Male-Friend Leech Without Becoming the Villain
Diagnosis without a remedy is just anxiety. So here is the remedy — a field guide for gracefully setting roles, drawing boundaries, and unplugging the nightlights, without a single dramatic confrontation.
1. Stop initiating. You do not need to announce anything. A friendship built on his extraction will quietly die of natural causes within a month once you stop watering it. You are not ending it. You are simply no longer feeding it.
2. Reroute him to the woman in his life. If he is partnered, send every emotional request home where it belongs. “That sounds like a conversation for Sarah, not me.” Said warmly, said once. Watch how fast a man who claimed pure friendship resents being handed back to his own girlfriend.
3. Keep one sentence in your back pocket. For the moment he escalates: “I’m not available for that kind of closeness with men outside my relationship. I value you as a friend, and I’d like to keep it there.” Then stop talking. Do not soften it into oblivion.
Notice what is not on this list: a fight, a betrayal, a cruel word, a dramatic unfriending. You do not owe anyone a spectacle. You owe yourself a clearing — a life with enough open sockets that the right love can finally find somewhere to plug in.
XII. Susanna's Verdict
Return to the garden, because the story does not end with Susanna's refusal.
The elders made good on their threat. They testified that they had caught her with a lover beneath a tree, and the court believed them — of course it did. They were judges. They were friends of the house. Susanna was sentenced to death.19
The easy thing — the survivable thing — was to let them have what they wanted and tell no one.
She refused anyway. “I will fall into your hands, rather than sin in the sight of the Lord.”
She set a standard so high that no amount of pressure could lower it — and she set it knowing it might cost her everything.
That is the bar. Not a wall against men. A standard — the refusal to let proximity, history, or fear of the fallout buy access that was never on offer. Susanna's ‘no’ did three things at once: it named the elders for what they were, it preserved her integrity, and — when Daniel finally exposed them — it made room for justice to arrive.20
* * *
I lost a lot of friends in my twenties. Or — more honestly — I gained a lot of clarity.
The men who disappeared when I got a boyfriend were not punishing me. They were simply admitting, by their absence, what they had always been doing.
The man with the condoms was not betraying my trust. He was telling me, in a language no woman is taught to read, what the weekend had always been about.
None of these men were monsters. They were obeying a biology I now understand better than most of them do.
But understanding their biology is not the same as funding it.
* * *
I do not have close male friends anymore.
I have male relatives. Male colleagues. Male staff. Men whose work I admire and whose company I enjoy in defined, bounded, professional ways.
What I do not have is a single man on standby who is waiting — waiting for the boyfriend to disappear, waiting for the marriage to wobble so he can advise and be a shoulder, waiting for the small civilizational accident that would let him collect on a debt I never agreed to owe.
I sleep better. I feel more enriched by my friendships because the boundaries and intentions are clear. There’s room for the lamp to arrive.
* * *
And somewhere out there, in a garden full of elders who call themselves friends, a woman is being asked to lower her standard just slightly, just this once, just to keep the peace.
I hope she refuses.
With love always,
Amanda
P.S. Of course men WANT to be your ‘friends’ they want access to your energy, to the status you lend them, to your love and care and affection, to your beauty, and to the possibility that maybe one day you just might sleep with them…. If that’s what you consider true friendship, by all means, have at it. And if that’s not your idea of true friendship, set a boundary with them, don’t try to convince them of their true intentions. Because a thirsty man will never turn away free water, it is up to you to say when enough is enough.
