Understanding Men is a series of articles and videos that progressively explain the many natural factors that help us see men in a realistic light.  Today's world is filled with negative spin on men and masculinity and this has done great harm to men and boys.  That harm is amplified by the media and the educational systems ignoring an abundance of research knowledge that reveals what is driving healthy masculinity and healthy manhood.  This series digs into that research and clinical observations and offers it for your consideration. Understanding Men will be open to all subscribers and will not require a paid subscription.  If you would like to support my work that would be great but not a necessity.  Look for it each Wednesday. Men are good!

 We start with Testosterone.

In order to understand men and boys you must understand testosterone. This section will give you a good start in beginning to appreciate the importance of testosterone to boys and men.  It starts before you were born. This is an excerpt from my book for mothers about their boys.

It Starts Early

The differences between boys and girls start very early. In fact they start the first day of life. Research has shown that infant boys are more likely to attend to an object or a mobile while infant girls are more likely to attend to a human face.1 But why this difference so shortly after birth? With no socialization to influence boys or girls at day one how is it that there might be differences? This is where we need to back up about 6 or 7 months.

THE TESTOSTERONE FLOOD


At approximately 8-24 weeks in utero most boys receive what is called a testosterone flood. This sudden increase in testosterone has multiple consequences. One consequence is that these raised levels of testosterone change the brain of the baby. The default brain is the female brain or what researcher Simon Baron-Cohen calls the “relational” or “empathic” brain.2 This relational brain is built to focus more on empathy, nurturing and relationships. Without the testosterone flood we would all have this relational brain, but with the flood, the brain starts to develop into what researchers call the male brain or what Baron-Cohen calls the “systemizing brain.” This male brain has a different set of strengths. It prefers to focus on systems: what makes them tick, what removing one piece might do to the whole, what a simple change in one part might do to another, the joy of building it piece by piece or taking it apart. Think Legos. Can you remember little boys spending hours upon hours with Legos? I bet you can. I would also bet that you might remember a similarly aged little girl that loved Legos in about the same way. And here is where things get interesting. It turns out that a small percentage of females also get an increase in testosterone in utero and develop what researchers call male brains.3 The girls who get this testosterone tend to be much less interested in traditionally feminine sorts of things, they would rather play rough and climb trees and spend hours with Legos. They tend to feel more happy being with the boys and they will often reject ostensibly female things. What we know now is that these young ladies are unique as girls at least in part because they got this extra testosterone and it is this pre-natal testosterone that is playing a part. I’m sure you have known some of these girls before; we call them “Tom Boys.”

It’s important to note that there is also a small percentage of boys who do not get this testosterone flood and therefore have a more “female” brain. These are the boys that are easier for moms to understand. They are more like mom and their way of being in the world is more like mom is used to. If you have a son like this (and if you have a “female brain”) you may be close due to your similarity. This is the young man that makes the mom wonder why her other sons can’t be like that.

Researchers have been able to identify those boys and girls who experienced this extra testosterone and they have studied these boy’s and girl’s behaviors and personalities as they have gotten older. What they have found is that those with greater testosterone levels in utero are more likely to want to play with “boy” toys like trucks and things that move. They are more likely to be more active, aggressive and competitive, less interested in traditionally feminine things and less interested in infants and nurturing behaviors.4,5 Those with lower levels of testosterone are more likely to have more interest in dolls and playing house, to be more interested in nurturing and in sharing secrets and personal data, and to prefer to play with a single friend or two, rather than with a larger group. Of course parents have been seeing these differences for a long time but likely assumed these differences were based solely on socialization, not on biology. Now we know differently. There are many factors that impact our differences.

A good deal of research is being done on the testosterone flood and how it influences children. As of 2020, scientists are confident about four connected differences from this flood. These are the boy-typical play behaviors, the increased chance of early aggressive behavior, influence on the core sexual identity and an impact on sexual orientation.6 There are other differences that are being studied but the strength of connection has yet to be proven for these.

What does this tell us? It suggests that your son, if he had the testosterone flood, will probably like to play in a way that most boys like to play, he may be interested in masculine play and be turned off by feminine activity. He will likely be attracted to females when he matures and he may be aggressive at times.

Our personalities are impacted by our biology even before we are born. This goes against common knowledge that our socialization is the only determinant to our ways of being. This is false. Our prenatal testosterone is just one biological factor and it impacts us in a profound manner. This testosterone flood has what biologists call “organizational” qualities. That is, the testosterone organizes the brain in certain patterns, literally changing the brain’s structure.7 These patterns make up what is being called the male brain. In addition to testosterone’s organizational qualities it also sensitizes receptor cells in the brain to be more reactive so that later in life the bodies of the boys and girls who received this flood will be more reactive to testosterone. This is called testosterone priming. Lastly, testosterone has what scientists call activational qualities. These are more transient and non- permanent effects on an already developed nervous system. This is what most of us think of when we think of hormones and the way they work. We get a squirt of this or that hormone and our bodies react accordingly.

Prenatal testosterone is not the only time when there is a surge in testosterone within boys’ bodies. A second surge of testosterone happens shortly after baby boys are born. Some scientists are calling this the “Mini Puberty.”8 This surge lasts between the first to third month of life (and sometimes longer) and is being studied now to get a sense of what impact it might have on these young boys. This surge is considerably easier to study since direct measurements of the testosterone can be made on a regular basis and do not depend on the blood levels of the pregnant mother or the testosterone levels in the amniotic fluid.

And, of course, there is the flood of testosterone that we are all familiar with, when boys reach puberty and once again their bodies are flooded with testosterone, about ten times the levels of testosterone that their sisters experience.

SYSTEMIZING

Let's take just a minute to examine what is meant by the systemizing brain that seems to result from the testosterone flood. This systemizing brain prefers to focus on systems. But when we say systems, what do we mean? These systems might be about anything with an input and an output. An example might be a machine like a car. It has numerous driver “inputs” like steering, braking, and accelerating. Change one of the inputs and the system changes. Learning how these inputs change the outputs is learning the system. A mainframe computer would be a more complex example. Or take a simpler example like Legos, there are a multitude of ways to attach the pieces, different colors, and different shapes. Learning the system is learning how to manipulate the inputs to get the output you might want. Another system might be swinging a baseball bat. The swing itself is a system. Learning the different parts of the swing, learning how to adjust that swing, and various different ‘inputs” the ball player could use to get the desired outputs is a system. Systems can even be as simple as a phonebook where names and numbers are connected or as complex as a philosophy. Our worlds are filled with systems.

WHAT WE TALK ABOUT

An easy way to get a sense of this difference in the systemizing brain and the empathic brain is to think for a moment about the topics of conversations of your sons and of your daughters. What sorts of things do your sons like to talk about? I would bet that they talk about systems or competing, and sometimes both. Talking about video games is talking about systems: input and output and which inputs bring success. Boys can talk about video games for hours. What was done, what worked, what didn’t, and all the gory details of the experience. (Of course they would prefer to play them and not talk.) I am willing to bet you have heard these conversations before. Discussing sports is another system: who is winning, what Team A needs to do to be more competitive against Team B, and on and on. The other piece is that in both these topics there is a likelihood that the discussion centered around competition. Who is first? Second? Last? Who is a level up and who is five levels behind? And this of course is a part of the system.

Now contrast this with the typical discussion you might hear with girls. Sure the girls might talk about sports or video games but it seems more likely they will talk about relationships. Who is their best friend, what are they doing together? Who will or won’t play with whom? Disclosing this or that personal data. Hearing about others’ relationships. This is what you are more likely to hear from your girls. Some girls, however, will love to talk about sports and some boys will be more interested in relationships. What we are talking about is not a predictor of behavior but is a way of observing it. You can’t say, “Because he is a boy, he will do this or that.” But you can simply observe how your child may or may not fit in with the differences we are describing and build a deeper understanding of their uniqueness. Once we observe we can see how this plays out in the lives of our children.

The Women's Health Narrative Meets the DATA

What if one of the most common claims in health policy simply isn’t true?

We’ve all heard the refrain: women are underfunded, under-researched, and left behind by the medical establishment. It’s repeated so often that most people never stop to ask for the evidence.

In this roundtable, Jack Kammer, Ed Bartlett, Ed Stephens, Jim Nuzzo, and I compare that narrative with the available data. We examine research funding, clinical trial participation, life expectancy, and the unintended consequences of policies that consistently prioritize one sex while neglecting the other.

This isn’t an argument against women’s health. It’s an argument for evidence, fairness, and a healthier future for everyone.

Feminism Cannot Be Reformed: It Must Be Destroyed Root and Branch

Janice Fiamengo’s new book is out, and this excerpt from the Foreword gives you a pretty good idea of what to expect. Janice goes straight to the heart of feminism and gives ample reasons for its demolition.

This is an important book. I hope you’ll get a copy for yourself—and maybe send one to someone who is even a little bit open to seeing the reality of feminism rather than the equality mask presented by feminists and so much of the media.

Well worth watch it’s good seeing men calling out women’s bull shit when the same women are not use to fair honest responses!

From Shooter to Heroine: The Glorification of Feminist Violence

I recently joined Hannah Spier, Janice Fiamengo, and Jim Nuzzo for a fascinating discussion about one of our culture’s most striking double standards: why violence by women is so often explained, excused, or even celebrated, while violence by men is treated very differently. We examine Valerie Solanas, the attempted murder of Andy Warhol, the SCUM Manifesto, and the film I Shot Andy Warhol, asking what the celebration and romanticizing of Solanas reveals about gynocentrism, empathy, and cultural bias. I think you’ll find it both thought-provoking and eye-opening.

The Femosphere Pipeline
How feminist ideas travel from academia and advocacy into culture, policy and law



All we hear about these days is a dangerous manosphere that is threatening our young men. Actually the manosphere is a fairly small and widely varied group of male-oriented communities that has been billed as a huge threat. All the while there is something much larger and much more dangerous that is surrounding both the manosphere and our culture. It is embedded in all that we do, I call it the Femosphere. This huge complex contains, academia, education, advocacy organizations, legislatures, government agencies, entertainment, the courts and of course, the media all working together to create and maintain a gynocentric narrative that impacts everyone.

This is the mammoth sphere through which feminist and gynocentric ideas are created, validated, circulated and converted into public policy. It is the invisible system that makes feminist claims seem unquestionably true. This goes on day in and day out and is a huge and destructive machine that no one sees. No one identifies it as ideological or biased in any way. It masquerades as the status quo. If there is a sphere that is dangerous, it is surely the femosphere.

Here’s how it works. A new slogan or concept is created in academia or feminist advocacy and then reinforced by both. The feminist advocates promote it. Journalists print it. The public reads it. Educators teach it. The public learns it. Before you know it, government agencies are incorporating it into trainings and reports. Then the legislators push it into policy and law and the courts follow along using the same ideas that prompted the policies and laws. Unprecedented teamwork, and no one sees it.

Take coercive control as a​n example. The term was first used by domestic violence advocates who described abuse as an ongoing pattern of control rather than a series of isolated violent acts. Evan Stark pulled these ideas together into a formal theory of coercive control in his book “Coercive Control: How Men Entrap Women in Personal Life (2007)“. (The title states clearly that this was not a gender-neutral theory: men were the oppressors and women were their victims.) Then the feminist advocates promoted it, journalists spread the word, educators and government agencies taught it, and police and courts were trained to use it. Eventually the legislators turned it into law. Hey Presto! The idea of male dominance and men’s violence becomes the default,

There are plenty of other examples like hegemonic masculinity or intersectionality. These all have different paths through the femosphere pipeline but the end product is the same. The specific ideas about male dominance travel from idea to law or common knowledge. The process is similar, an idea about power and male dominance begins in academia or advocacy, moves through the institutions, and eventually gains real social, political and sometimes legal power.

Here’s the tricky part. Each of these groups starts to quote the other groups as proof to the veracity of the original idea. Journalists cite the academics and advocates cite the journalists. Politicians cite both. Then the researchers come along and “study” the reality that has just been created out of thin air and prove it. Then the public hears from these many sources and voila, what started as a theory becomes an accepted reality. Advocacy becomes fact. The public nods unknowingly in agreement.

The manosphere is open season for criticism, targeting, restrictions, and containment. The femosphere is protected by a gynocentric ban on any criticism or even a negative idea in their direction. To expose who has the power just look for who cannot be criticized. That would clearly be the femosphere, women and feminism. In fact, the manosphere is the first public criticism of the femosphere and the response is predictable: Shame it, blame it, and call it pure misogyny. Don’t argue the ideas, attack personally.

This is what we have had for the last 50 years. A slow gynocentric building of a new reality. And what has been the result? Women have been inflated and men have been equally deflated. Ask just about any woman about the last 50 years and she will tell you it is progress. But has it truly been progress—or has it been a one-way transfer of concern, opportunity, and power to women, without any corresponding transfer of responsibility?

And now it is basically impossible to see.

The next time you hear someone complain about the manosphere, ask them when they will be complaining about the real problem, the femosphere.

Sculpting the Narrative
How researchers can build the desired conclusion into the questions they ask



I recently came across an article with a rather alarming headline:

“Nearly One in Five Australian Men Say Violence Against Feminism Is Legitimate, Study Finds.”

That certainly got my attention. Nearly 20 percent of Australian men think violence against feminism is legitimate? That’s a lot of men. So I decided to look at the study. I’m glad I did.

The research comes from the University of Melbourne and was published in 2024. The researchers surveyed 1,020 Australians about misogyny, racism, and violent extremism. The 19.4 percent figure is real. But when you look at the question that produced it, things start getting interesting.

The men weren’t asked:

“Do you believe violence against feminists is legitimate?”

They weren’t asked:

“Is it acceptable to physically attack feminists?”

They were given this statement:

“Feminism is damaging to our society and should be resisted by force if necessary.”

That is what produced the 19.4 percent. Do you see the problem? There are several things going on in that one sentence. First, it says feminism is damaging to society. That’s one question all by itself. Then it says feminism should be resisted “by force.” What does force mean? Physical violence? Political force? Legal force? Economic force? Civil disobedience? We don’t know. And then come the two little words that really caught my attention:

“if necessary.”

What does that mean? Those words ask the respondent to imagine circumstances in which force might become necessary. Most people believe there are circumstances in which force is justified. Self-defense is an obvious example. Protecting another person is another. Resisting tyranny might be another. But none of that is explored. Instead, agreement with this rather strange question eventually becomes:

“Nearly One in Five Australian Men Say Violence Against Feminism Is Legitimate.”

That’s quite a journey.

​Here’s a screenshot of the questions they used to determine if violent extremism existed and to what degree. Can you find the question(s) that did not have the word violence in any form in them? Can you find the question(s) that concluded by saying “if necessary?” They abbreviate violent extremism with “VE.” Here’s a clue….look at the last question very carefully and then compare.

Where’s Waldo?

 


Can you see how they have sculpted things? Which got the highest scores? The one without the word violence and justified by saying “when necessary.” Then you make claims, even in your own paper, the same one that relied on that questionable question that​:

 

Now they call it anti-feminist violent extremism! No need to ask the question with the word violence in it? Nope.

Then I Looked at the Other Questions

This is where things became even more interesting. The study includes a table with the heading:“Frequency of Respondents Agreeing with Permissibility of Violence Against Women.”

Okay. If we are going to measure whether people think violence against women is permissible, what should we ask? Fortunately, the researchers give us a couple of good examples. One question says:

“A male partner would be entitled to use physical force (pushing, slapping, punching, kicking, choking) if his female partner argues with him, or refuses to obey him.”

That’s pretty clear. No ambiguity there. Do you think a man is entitled to push, slap, punch, kick, or choke his female partner because she argues with him or refuses to obey him? 5.5 percent of the men agreed. Another question asks whether a father or brother is entitled to use physical force or violence against a daughter or sister for bringing dishonor on the family. Again, very clear. 4.5 percent of the men agreed. Those are troubling numbers. I would prefer they were zero. But notice what happens when the researchers ask clear questions about whether violence against women is actually permissible. We get 5.5 percent. We get 4.5 percent. Now look at some of the questions that produced the big numbers.

Is This Really a Question About Violence?

Here’s one:

“Women often make sexual assault accusations as a way of getting back at men.”

48.6 percent of the men agreed. Nearly half! But wait a minute. What does that question have to do with whether violence against women is permissible? A man could believe that false sexual assault accusations are common and at the same time believe that violence against women is absolutely wrong. Whether his belief about false accusations is correct is another question. We can investigate that. But believing something about false accusations does not mean you approve of violence. Here’s another:

“Women going through custody battles often make up or exaggerate claims of domestic violence in order to improve their case.”

51.2 percent of the men agreed. There’s the biggest number on the page. But again, where is the approval of violence? This is a question about whether women sometimes make false or exaggerated claims during custody disputes. You can think that belief is right. You can think it’s wrong. But it still isn’t a question about whether hitting women is okay. Yet there it sits under the heading:

“Permissibility of Violence Against Women.”

How did we get there?

Another Curious Question

Then there is this one:“Sometimes a woman can make a man so angry that he hits her when he didn’t mean to.”

33.5 percent of men agreed. But what exactly are they agreeing with? That hitting her is justified? The question doesn’t say that. It asks whether someone can become so angry that he does something he hadn’t intended to do. Surely there is a difference between explaining how something happened and saying that it was acceptable. Interestingly, 21.7 percent of women agreed with this statement too. Are those women endorsing violence against women? Maybe. But the question doesn’t tell us. That’s the problem.

Look at the Pattern

This is what really struck me. The questions that explicitly ask whether men are entitled to physically assault women produce relatively low numbers: 5.5 percent. 4.5 percent. But questions about false accusations, custody battles, anger, and responsibility produce numbers of: 33 percent. 37 percent. 49 percent. 51 percent. And which numbers do you suppose make the story look more frightening? This is where I started thinking about the phrase sculpting the narrative. You begin with the raw material—the answers people actually gave. Then you decide what those answers mean. A belief that women sometimes make retaliatory sexual assault accusations becomes an attitude about violence against women. A belief that domestic violence allegations may be exaggerated during custody battles becomes an attitude about violence against women. Agreement that feminism should be resisted “by force if necessary” becomes support for violent anti-feminist extremism. And eventually a newspaper headline tells us: Nearly one in five Australian men says violence against feminism is legitimate. But that isn’t what the men were asked.

Why Does This Matter?

Violence against women is a serious subject. That’s exactly why the research needs to be good. If you want to know whether men approve of violence against women, ask them. The researchers clearly knew how to do this. Their own questionnaire proves it. Ask: Is a man entitled to hit a woman under these circumstances? They did. And they got 5.5 percent. Ask: Is a father or brother entitled to use violence against a daughter or sister under these circumstances? They did. And they got 4.5 percent. Those are legitimate findings. But if you ask men whether women make false accusations and then treat their answers as evidence of the permissibility of violence against women, you are measuring something else. And shouldn’t PhD researchers know the difference?

​I am aware that this is tough to believe so here is a screen shot from the research that shows the questions and the responses. Note that their highest responses were the ones that had little to do with violence against women.

 



From Survey Answer to Extremism

There is another step in all of this that bothers me. The study doesn’t stop with attitudes toward women. It connects these attitudes with violent extremism. The researchers report that anti-feminist violent extremism was the most prevalent form of violent extremism they measured. That sounds frightening. But remember the question that helped establish it:

“Feminism is damaging to our society and should be resisted by force if necessary.”

That’s it. Imagine changing the subject: “Racism is damaging to our society and should be resisted by force if necessary.” How many people would agree? Probably quite a few. Would we then conclude that those people support violent extremism? What about: “Nazism is damaging to our society and should be resisted by force if necessary.” Would agreement make you a violent extremist? Suddenly the problem becomes easier to see. The wording matters.

And Then the Media Gets Hold of It

By the time the research reached the media article I first read about this, most of these qualifications had disappeared. “Force if necessary” became violence. Agreement with a complicated hypothetical statement became believing violence is legitimate. An association between attitudes became a radicalization pathway.

​The researcher’s own university offered this headline:

 

​or this one from the Australian

 


​with pictures like this:

 

​Imagine being a new reader of this article. People tend to put their trust in the media and even more trust in “research.” How could they come away from this article with anything but the sense that a surprisingly large number of men are dangerous to women and to feminism? And yet when you go back and look at the actual questions, that isn’t what the research established. That’s how a narrative gets sculpted.​
​​
​The​ original story expanded to teenage boys, Andrew Tate, rape, women being killed, terrorism, and national security. That’s quite a sculpture. And somewhere underneath all of it are the actual survey questions. I don’t know the motives of these researchers, and I don’t need to. I’m interested in something much simpler. Did the questions measure what the researchers say they measured? When I look at this study, I have serious doubts. And perhaps the most revealing evidence comes from the researchers themselves. When they asked men directly whether a male partner was entitled to push, slap, punch, kick or choke a woman because she argued with him or refused to obey him, 94.5 percent did not agree. That seems like an important finding. Funny how that didn’t make the headline.

The Story Beneath the Surface: A video by Gabbi Wolfe

A while back, I had the pleasure of being interviewed by Gabbi Wolfe, a therapist who specializes in male psychology. After our conversation, she read the second edition of The Way Men Heal and recently sent me this video.

I was blown away.

What makes this video so powerful is that Gabbi doesn’t simply tell us how men grieve and heal. She tells us a story.

And it’s a remarkable story—one that draws you in, takes a turn you probably won’t see coming, and, before you quite realize what’s happening, gets under your skin.

Through the life of one man, Gabbi shows us grief expressed not primarily through words, but through action. She shows us healing through challenge and purpose, and the extraordinary power of something very simple: men standing shoulder-to-shoulder with other men.

She also weaves some of my work into the story, including an excerpt from our interview and the metaphor from Swallowed by a Snake.

I think she did a remarkable job. But more importantly, she helps us see something about men that is very easy to miss when we look for grief only in tears and words.

This one stayed with me. I think it may stay with you, too.

I hope you’ll take the time to watch it.
