Who Was the Unabomber? Ted Kaczynski and the Unopposed Mind
Updated: Oct 13
On September 25, Netflix released its Unabomber film, and one name went back into everyone's search bar: Ted Kaczynski.
The question people leave the film with is always the same. How does a math prodigy who entered Harvard at sixteen become a man who spends seventeen years mailing bombs to strangers?
The film offers an answer. There was an experiment at Harvard, and it broke a boy. While you watch, you believe it. The story is well built, and the human mind loves a catastrophe with a single cause.
I'll admit I'm less certain. I have spent years writing about intelligence and working with very bright people, and I see something else in this story. Let me tell you what happened first, then what I see.
Who was the Unabomber?
"Unabomber" was the name the press gave to Theodore John Kaczynski, who sent or planted 16 bombs in the United States between 1978 and 1995, targeting universities, airlines and people connected to technology. Three people were killed and 23 were injured. The name came from the FBI's case code, UNABOM: University and Airline Bombing.
Kaczynski was arrested on April 3, 1996. On January 22, 1998, he pleaded guilty and was sentenced to life in prison without the possibility of parole. He died on June 10, 2023, at 81, in a federal prison medical center in North Carolina.
Ted Kaczynski's story
He was born on May 22, 1942, near Chicago. A test in fifth grade put his IQ at 167. He was moved up a grade and placed among older children. He was always the youngest in the room. Keep that in mind. I'll come back to it.
In the autumn of 1958, at sixteen, he started at Harvard. He earned his PhD in mathematics at the University of Michigan, where his dissertation won the Sumner B. Myers Prize for the best thesis in the field that year. In 1967, at 25, he became an assistant professor at Berkeley. Two years later, he resigned.
In 1971, he built a cabin in the woods near Lincoln, Montana. FBI records put it at roughly three by four meters. He lived there for twenty-five years. He sent his first bomb in 1978.
The Harvard experiment: what happened in Murray's room?
At the center of the film is a study run at Harvard by the psychologist Henry Murray. Murray was one of the best-known personality psychologists of his time. He co-created the Thematic Apperception Test, still in use today, and during the Second World War he designed psychological screening for the OSS, the American intelligence agency.
The study ran from autumn 1959 to spring 1962, with 22 undergraduates. Each was given a code name. Kaczynski's was "Lawful." He was seventeen when it began and, according to the writer Alston Chase, one of the youngest and poorest participants.
The students were told they would spend about two hours a week on research that would help solve psychological problems. First they were asked to write an essay describing their philosophy of life, their most deeply held beliefs. Then they were told they would debate that philosophy with another student.
That is not what happened.
Each student was taken into a brightly lit room with a one-way mirror on one wall. Electrodes recording heart rate and breathing were attached to their body. A film camera behind a hole in the wall recorded every movement. The person across the table was not a student. He was a talented young lawyer who had been told to be aggressive. He had the student's essay in his hands, and he took it apart, line by line. In Chase's account, the attack was designed to be "vehement, sweeping, and personally abusive." Its target was the student's most cherished beliefs.
It didn't end there. Over the following year, the students were called back again and again, and in some sessions they were shown film of themselves: footage of how they had been pushed into helpless anger. By the end of three years, each student had given the study around two hundred hours.
One participant, twenty-five years later, still remembered the anger, the shame, the glass and the electrodes. Another described being so shocked by the ferocity of the attack that he was too helpless to respond.
No study like this could be run today. Misleading participants about the distress they will experience violates the principle of informed consent. Kaczynski's file is still sealed. Chase was able to see the coded records of the other participants, but not his.
I wish the film had told only this part.
Having watched every documentary released before it, I found the film fragmented. It could have gone much deeper psychologically. It felt like reading the introduction and the conclusion of a book, as if the decades in between never happened. If you want depth, I'd recommend Netflix's four-part 2020 documentary Unabomber: In His Own Words. As the title says, you hear Kaczynski in his own voice, and his brother David is among those who speak. It's a good place to start if you're curious about the years the film skips.
The film weaves the Harvard room together with the FBI's long manhunt. I understand why. Audiences love a hunt. But we already know the hunt. It has been told many times. The story we don't know, or rather the one we rarely dare to look at, is in that room.
A seventeen-year-old boy, the youngest and poorest in his class. No one to ask about what was happening to him. One of the most respected universities in the world asks him to write down the ideas he values most, then humiliates those ideas under bright lights, on camera. And it does this in the name of science.
Those three years are a film on their own. No bombs, no chase. Just what an institution can do to a brilliant child. That is the truly frightening part.
Still, I have to be honest, because I don't want to tell a story as persuasive as the film's. There is no proven link between the experiment and the bombs. Chase himself writes that we don't know what effect the experiment had on Kaczynski. Test results later reviewed by an independent expert suggested he was psychologically sound at the start of the study; the psychiatrist who evaluated him for the court saw the first signs of distress towards its end. Kaczynski himself said, years later, that he was fairly sure the experiment had no significant effect on his life.
And 21 other students walked into the same room. As far as we know, none of them built a bomb.
What did the Unabomber manifesto say?

In 1995, Kaczynski said he would stop the attacks if a long text of his was published. The roughly 35,000-word Industrial Society and Its Future appeared as a supplement to the Washington Post on September 19, 1995. Its first sentence read: "The Industrial Revolution and its consequences have been a disaster for the human race." The text argued that technology had not freed people, but had taken control of their own lives away from them, step by step, and handed it to the system.
It was this text that gave him away. His brother David's wife, Linda Patrik, recognised a familiar voice in it. David took out old letters, compared them, and went to the FBI.
At a time when artificial intelligence makes a few more decisions for us every day, it doesn't surprise me that people are rereading this text. But I have to draw a line here. An idea can contain a true observation. Killing people does not make that observation right. It makes it worthless. Kaczynski had one of the brightest minds to ask his question, and he wrote his answer with three human lives.
Is intelligence to blame?
There is a common mistake when this story is told: treating intelligence itself as the suspect. "So that's what happens when you're too smart."
I have written before about how fragile very bright people can be, and how they learn to hide the wings of their minds. I stand by that observation. But the research paints a more careful picture, and I owe you that.
A 2024 meta-analysis in Gifted Child Quarterly brought together 27 studies on anxiety and 15 on depression in gifted individuals. The result: gifted people are not more anxious or more depressed than their peers. If anything, the small difference runs in their favour.
So intelligence doesn't break people. Then what does?
The Unopposed Mind
When I look at Kaczynski's life from beginning to end, I see one thing repeating. At every stage, the people who could have disagreed with him disappear, one by one.
As a child he is moved up a grade and loses his peers. Remember, always the youngest. At Harvard, the same. At Berkeley he stays two years and leaves. Then the woods. For twenty-five years, not a single person to test his thinking, to say "wait, you're wrong here."
I call this the Unopposed Mind.
It is not the same as loneliness. You can be unopposed in a crowd, and you can live alone and still argue with someone every day. The definition is this: a mind that never meets another mind capable of testing what it produces.
And here is the crucial part. An ordinary mind, left unopposed, makes mistakes. A very powerful mind, left unopposed, turns its mistakes into a system. It closes every gap, refutes every counterargument in advance, and builds a 35,000-word structure that looks flawless. Intelligence doesn't act as a brake here. It acts as an accelerator. A good engine heading in the wrong direction goes further than a bad one.
The film shows this, perhaps without meaning to. What happened in Murray's room was not disagreement. It was attack. The two are very different. Disagreement is aimed at your thinking and takes you seriously. Attack is aimed at you and makes you smaller. If a young person never learns to tell them apart, they may later treat every disagreement as an attack and close the door for good. We can't know whether this happened to Kaczynski. But it is a pattern we often see in brilliant people.
How was the Unabomber caught?
His language gave him away.
For seventeen years, the FBI had no trace that could lead to him. All they had were words. FBI profiler James Fitzgerald compared the manifesto, line by line, with the old letters David had brought in. Both texts shared the same habits. British spellings like "analyse" instead of "analyze," "licence" instead of "license." And one idiom. In English, it is usually said that you can't "have your cake and eat it too." Kaczynski, in both the manifesto and the letters, wrote it the other way round: "eat your cake and have it too."
That comparison helped secure the search warrant for the cabin in Montana. It was reportedly the first time an American judge approved a search warrant based on linguistic analysis. The 2017 series Manhunt: Unabomber tells exactly this story.
Forensic linguistics was not born with this case; the term had been in use since the 1960s. But this case made the field visible and legitimate. Fitzgerald later earned a master's degree in linguistics and became the FBI's first trained specialist in the field.
What strikes me most is this: a man who spoke to no one was caught by the way he spoke. This is my interpretation, but for twenty-five years no one had read what he wrote and said "that's not how the saying goes." His language, like his thinking, had stayed unopposed, and entirely his own.
Three men who went into the woods: Thoreau, Into the Wild and Kaczynski
Retreating into the woods is not, in itself, a symptom. Some of the most loved stories in literature and film are about exactly that. Two names are enough to see the difference.
In 1845, Henry David Thoreau built a cabin on the shore of Walden Pond in Massachusetts and lived there for a little over two years. Walden is the book of those years. His cabin was almost the same size as Kaczynski's. But Thoreau's cabin had something more. In the chapter "Visitors" he writes: "I had three chairs in my house; one for solitude, two for friendship, three for society." He had guests. He could walk to town. He had chosen solitude, but he hadn't closed the door.
Into the Wild is a film I love. Sean Penn's 2007 adaptation of Jon Krakauer's book tells the true story of Christopher McCandless, who gave everything away after graduating and went to Alaska. McCandless died alone in an abandoned bus in 1992. Before he died, he wrote a note in the margin of the book he was reading: "Happiness only real when shared." For me, that line carries the weight of the whole film.
All three men went into the woods. Thoreau went with three chairs and came back after two years. McCandless went alone and, in the end, wrote that he needed others. Kaczynski stayed for twenty-five years and waited for no one.
The woods made no difference. Whether the door stayed open did.
Where does social isolation fit in?
Kaczynski's life is also a story of social isolation. Two words need to be separated here. Loneliness is a feeling; you can feel lonely in the middle of a crowd. Social isolation is a condition: a real reduction in contact, relationships and conversation. Kaczynski's was the second, and it was built step by step. First he lost his peers, then his colleagues, then everyone.
According to a World Health Organization report published on June 30, 2025, one in six people worldwide is affected by loneliness, and loneliness and social isolation are linked to around 871,000 deaths a year. So this is not something peculiar to a cabin in the woods. It happens in the middle of big cities, between full calendars.
The harm isolation does to health is widely discussed now. Less discussed is what it does to thinking. An isolated person doesn't just feel sad. Their thinking goes unchecked. When no one asks "are you sure?", you become sure.
The Unopposed Mind is what social isolation looks like inside thought. Isolation is the shortest road there, but not the only one.
Why is it easier to be unopposed today?
Kaczynski had to go into the woods to become unopposed. Today, there's no need.
We now have tools that never disagree with us, that develop every idea we have and polish every draft. As someone who works with AI, I say this with real appreciation: their value is enormous. But there is a risk too. People become very comfortable with a conversation partner who always agrees.
There is another way to become unopposed: power. On the day Kaczynski died, June 10, 2023, someone posted the first sentence of the manifesto. Elon Musk replied with one line: "He might not be wrong." That is an oxymoron in itself. A man who built his fortune on technology, who is trying to put chips in brains and send people to Mars, agreeing with a text that calls technology a disaster for humanity. We can debate the observation in that sentence; I did, above. What makes me think is how easily a man who killed three people can be agreed with, and how the contradiction stops no one.
You don't have to be alone to be unopposed. Sometimes it is enough to be powerful enough.
What does this mean for our own lives?
Moving our children up a grade is easier than helping them find friends. Putting a brilliant employee alone in a room and saying "she'll handle it" is easier than building a team that can challenge her. Admiring our own idea is easier than explaining it to someone who loves us but disagrees.
What made Kaczynski dangerous was not his intelligence. It was that no one was left who could tell him, "you're wrong."
Everyone has a cabin. Some are in the woods. Some are inside our own ideas.
Who changed your mind in the past year?
If no name comes to mind, the reason can't be that you are right about everything.
