Ted Kaczynski, the Unabomber, was a math prodigy with an IQ of 167, but his own manifesto led to his capture by his brother David. The publication of his anti-technology writings in 1995 turned his words against him.

Why is the Unabomber so famous?
Ted Kaczynski, known as the Unabomber, conducted a 17-year bombing campaign that killed 3 and injured 23. His fame stems from the publication of his anti-technology manifesto in The Washington Post and The New York Times, which led to his identification by his brother.
What made the Unabomber stand out among other serial killers?
Unlike most serial killers, Kaczynski was a former mathematics professor with a genius-level IQ. He targeted academics and technologists, and his detailed manifesto offered a coherent ideological justification for his violence. The FBI described the case as one of the longest and costliest in its history.
The manifesto was published under threat of further violence, a rare concession to a domestic terrorist.
What was Ted Kaczynski’s IQ?
Ted Kaczynski’s IQ was estimated at 167, placing him in the genius range. Multiple profiles describe him as a child prodigy. Some biographical accounts report a score of 165, showing minor variation across secondary sources.
What is Stephen Hawking’s IQ level?
Stephen Hawking’s IQ was reportedly around 160. While not officially confirmed, estimates place him in the same high range as Kaczynski.
What is the average serial killer’s IQ?
The average serial killer’s IQ is around 90–95, though some may be above average. Kaczynski’s 167 is far above that norm.
To put these numbers in perspective, here is a comparison table.
| Person | IQ | Notes |
|---|---|---|
| Ted Kaczynski | 167 | Genius, child prodigy |
| Stephen Hawking | ~160 | Theoretical physicist |
| Average serial killer | 90–95 | General population average ~100 |
The implication: Kaczynski’s intellect was exceptional even among high achievers, yet he used it to justify extreme violence.
What was the cause of the death of the Unabomber?
Ted Kaczynski died by suicide on June 10, 2023, at the Federal Medical Center in Butner, North Carolina. He was serving a life sentence without parole. The Federal Bureau of Prisons initially did not disclose a specific cause of death, though reports cited apparent suicide. Later summaries confirmed he was found unresponsive in his cell and pronounced dead of an apparent suicide.
Kaczynski’s death at age 81 ended a life that spanned from a remote Montana cabin to a supermax prison.
What was Ted Kaczynski’s ideology?
His ideology, outlined in the “Unabomber Manifesto” (formally titled Industrial Society and Its Future), opposed industrialization and technology, arguing that they erode human freedom. He advocated for a return to primitive, nature-based societies.
How did his ideology drive his attacks?
Kaczynski’s bombings targeted those he believed were advancing technological society – university professors, airline executives, and computer scientists. He saw himself as a revolutionary fighting against a system that destroys human autonomy.
“The industrial revolution and its consequences have been a disaster for the human race.” – Ted Kaczynski, from the manifesto.
Who ratted out Ted Kaczynski?
Ted Kaczynski’s brother, David Kaczynski, recognized the writing style of the manifesto and alerted the FBI. David and his wife Linda provided letters and documents written by his brother, and linguistic analysis confirmed the same author likely wrote the manifesto. David’s decision led to Ted’s arrest in 1996.
Did Ted Kaczynski regret what he did?
Ted Kaczynski expressed regret in letters but also maintained his ideological stance. He reportedly said he was sorry for the pain he caused his family, but he did not recant his anti-technology views.
“I loved my brother, but I could not let him kill again.” – David Kaczynski, on his decision to turn in Ted.
The catch: The very words Kaczynski hoped would spread his ideology became the tool that ended his campaign.
