On the surface, John Money was a celebrated psychologist and a pioneer in gender identity theory. But behind the academic prestige was an ideology that led to one of the most tragic cases of medical malpractice in modern history.

His experiment on David Reimer, a biologically male child who was forced to live as a girl, was perhaps well-intended, but ultimately a cruel attempt to prove that gender is nothing more than a social construct.

The result? A lifetime of suffering, irreversible damage, and a tragic ending that should have been a cautionary tale. And yet, here we are today—modern gender ideology is promoting eerily similar concepts, pushing children toward irreversible medical interventions in the name of “affirmation.”

The experiment that should have ended gender theory

The story begins in 1965, when twin boys Bruce and Brian Reimer were born in Canada. At just seven months old, Bruce underwent a routine circumcision that went horrifically wrong—his penis was irreparably damaged.

Distraught and desperate, the Reimer parents turned to Dr. John Money, a psychologist at Johns Hopkins University who was a rising star in the study of gender identity. Money had a theory: gender identity was entirely a product of environment, not biology.

He saw Bruce as the perfect test subject. The child was too young to remember or have much experience of his gender, and he had a twin brother who could serve as a control.

Money advised the Reimers to raise Bruce as a girl. He convinced them to change the child’s name to Brenda, dress him in feminine clothing, and reinforce female social behaviors. Trusting the so-called expert, the parents agreed.

By 22 months old, Bruce had undergone castration, and the world was told he was now a girl. Money used the case as evidence to promote his theory, claiming Brenda proved that biological sex could be overridden by socialization.

The devastating reality behind closed doors

In private, the reality was a nightmare. David (then Brenda) never felt like a girl. He rejected dresses, refused to play with dolls, and consistently exhibited masculine behaviors.

He fought against the role forced upon him, much to the frustration of Dr. Money, who was determined to prove his theory at any cost.

Even more horrifying were Money’s so-called “therapy sessions.” He forced Brenda and his twin brother Brian to participate in sexualized role-playing exercises meant to reinforce gender roles. The children were deeply traumatized. Brian would later develop severe mental health issues as a result of the psychological abuse.

By the time Brenda reached puberty, he was suicidal. The lie – though he didn’t yet know the full story – was destroying him. At age 14, his parents finally told him the truth: he had been born a boy.

The revelation was both a relief and a devastation. Brenda immediately reclaimed his male identity and took the name David. But the damage had been done. The years of forced gender confusion, coupled with Money’s abusive methods, left lasting scars.

The truth comes out, but is ignored

David began hormone therapy and underwent multiple surgeries to try and undo the physical damage of his childhood. He eventually married and tried to live a normal life. He even went public with his story to warn others about the dangers of gender ideology.

Despite his bravery, the suffering never truly ended. His twin brother Brian, unable to cope with the trauma, died by suicide. Just two years later, in 2004, David also took his own life at age 38.

John Money, the man responsible for their devastation, never faced consequences. He remained respected in academic circles, and his gender theories persisted. What should have been definitive proof that biological reality cannot be erased was instead ignored by ideologues unwilling to admit they were wrong… no matter the cost.

Modern gender ideology echoes the same mistakes

One might assume the world would have learned from such a horrific case. But disturbingly, the very ideas that destroyed David Reimer’s life are being championed today as progressive and compassionate.

Modern gender ideology insists that children who experience discomfort in their bodies should socially transition, take puberty blockers, and later receive irreversible hormone treatments or surgeries – all based on the belief that gender identity is separate from biological sex.

We’re told that children can know, as early as age three, that they were “born in the wrong body.” But David Reimer’s story demonstrates the opposite: children lack the cognitive capacity to make such life-altering decisions.

Childhood is a time of play, confusion, and discovery. Yes, there are effeminate boys and tomboyish girls. That doesn’t mean their natural development should be halted with drugs or surgery.

The long-term consequences are being ignored

The parallels between John Money’s failed experiment and today’s gender-affirming approach are deeply troubling.

We now see growing numbers of detransitioners, young adults who underwent medical transitions as teens and now regret the irreversible damage. I recently met Sorel Aldaco, who detransitioned after realizing the surgeries didn’t heal her mental health struggles. If anything, she now had more reasons to feel distressed.

She, like David, was promised that transitioning would cure her pain. Instead, it left her more broken.

But rather than learning from these tragedies, activists dismiss them as outliers. The same dangerous belief persists: that gender is purely a social construct. Yet science, history, and human experience all say otherwise. Biology always asserts itself.

David Reimer’s life – and death – should have been a wake-up call.

Why are we still doing this?

I’ve often wondered why this continues. Is it really just about ideology? Why is there a movement determined to put children on hormone blockers?

One answer I’ve heard repeatedly is this: many of the strongest advocates are older transgender individuals, particularly men, who wish they had transitioned sooner and believe young children should start early.

While perhaps understandable on a human level, this is not a scientific or ethical reason to impose irreversible decisions on children.

It’s the same mindset John Money had – perhaps meaning well, but refusing to face the reality that he caused immense harm.

The truth matters

David Reimer’s tragic story is a sobering reminder: ideological experiments on children have real, irreversible consequences.

Gender is not just a social construct. It’s deeply tied to human biology. No amount of hormone therapy or surgery can truly change that.

John Money’s experiment was a failure, but the greater tragedy is that the lesson has gone unheeded. If we truly care about children’s well-being, we must reject the dangerous ideology that cost David and Brian Reimer their lives.

Let’s not forget about John Money, about biological reality, and about the countless young lives now being placed at risk in the name of an idea that’s already proven deadly.

The Reimer twins’ story should be a warning, not a blueprint. Let’s make sure we never forget. And let’s ensure that history doesn’t repeat itself.
