Part One: The Fake Bomb Detector Grift That Killed Hundreds
A fake bomb detector that killed hundreds of Iraqi civilians was born not from advanced technology, but from a centuries-old psychological trick: the ideomotor effect. In this gripping first part of a two-part series, host Ted and guest Ed Zitron trace the lineage of deception from ancient dowsing rods and Ouija boards to 19th-century spiritism, revealing how the same unconscious muscle movements that made pendulums 'speak' to ghosts also made fake bomb detectors appear to work. The episode exposes how the ideomotor effect—where people unknowingly move objects based on their expectations—was exploited by con artists for centuries, culminating in a gaudy golf ball finder called the Gopher. That absurd gadget, designed as a joke, became the blueprint for a high-tech defense product sold to Iraq’s military, which falsely claimed to detect explosives. Despite having no scientific basis, it was trusted by officials who feared missing threats, leading to countless false alarms, wasted resources, and, ultimately, hundreds of deaths. The story is a chilling reminder that belief in technology doesn’t require truth—just the illusion of it. The episode underscores a deeper truth: people aren’t fooled by magic, but by the appearance of it. From Clever Hans the horse reading his owner’s body language to police dogs responding to their handlers’ biases, the pattern is consistent—humans project intelligence onto machines, and machines respond to human expectation.
The ideomotor effect causes unconscious muscle movements that make objects like pendulums and dowsing rods appear to move on their own, explaining why fake psychic tools and ghost boards work.
Dowsing has been practiced for over 6,000 years, with documented cases from ancient China, Egypt, and Rome, yet it has no scientific basis and relies entirely on unconscious human movement.
Even scientists like Michael Faraday and William Carpenter debunked spiritism and table-turning in the 1850s, but the ideomotor effect remained widely misunderstood for decades.
The same psychological principle that fooled 19th-century seance participants also fooled modern officials: the belief that a device works because it looks like it works, not because it does.
Police dogs often alert to drugs or bombs not because they smell them, but because they react to their handlers’ subconscious cues—proving that even trained animals can be manipulated by human expectation.

Introducing the Story of a Fake Bomb Detector
The host introduces the episode's central theme: a fake bomb detector that killed hundreds in Iraq, and how it was rooted in a centuries-old psychological trick—the ideomotor effect. He brings on guest Ed Zitron to explore the history of deception in technology.
The Ideomotor Effect: How Belief Moves Objects
“The ideomotor effect is when your thoughts or your like mental images of something cause a reflexive and generally unconscious automatic muscle movement.”
Dowsing Through History: From Ancient China to the 1980s
The episode traces dowsing from ancient Chinese texts to the 1980s, showing how the practice persisted despite scientific debunking. Even archaeology instructors in the 1980s were favorable to dowsing, proving how hard it is to dislodge belief.
The Scientific Breakthrough That Explained the Illusion
French scientist Chevruel conducted the first double-blind test on the ideomotor effect in the early 1800s, proving that pendulums and dowsing rods move due to unconscious human movement, not supernatural forces.
Spiritism, Seances, and the Rise of the Ideomotor Effect
The 19th-century spiritism movement used the ideomotor effect to create the illusion of ghost communication. Table turning, Ouija boards, and pendulums were all explained by the same unconscious movement, but belief in the supernatural persisted.
“The Gopher does not generate or transmit any harmful signals. is environmentally safe. That part is true. It does not generate or transmit any signals. What does it, does it just go? Nothing. It just moves with your hand. There's no, there's nothing in there.”
“What's really happening here is that loopholeism is the mechanism by which otherwise bright and even brilliant minds can trap themselves in nonsense.”
“Dogs are really good at knowing what we want. And dogs have no idea what alerting on a car means for the people in the car. No, of course not. They don't understand that. They're dogs.”
