University of Utrecht and the 15 Guilders Paid for a Psi Failure
By June Hargrove ·
Forty-one subjects were blindfolded with ping-pong balls in a study kept in CIA files for decades, only to prove that the "prototypical" path to ESP was a dead end.
Forty-one people sat in a room in the Netherlands with halves of ping-pong balls taped over their eyes and white noise pumping into their ears. They were paid a maximum of 15 guilders to try and see the invisible, only to be told that they had failed completely.
This was the cost of a "prototypical" experiment. The record, an academic paper titled "A PROTOTYPICAL GANZFELD PSI EXPERIMENT WITH A CONTROL CONDITION," was not produced by the intelligence community, but it was harvested by it. It sits in a CIA-RDP classified series, stripped of any internal agency summary or action memo. The record is a cold account of a total collapse: "no evidence of psi was found in either condition."
The Prototypical Failure
The experiment was conducted at the Parapsychology Laboratory, University of Utrecht, a research facility based in the Netherlands. The team consisted of A.C. van Dalen, L.R.B. Dias, and J.M.J. Murre—all researchers at the University of Utrecht—and S.A. Schoutent, a researcher at the same institution who developed the target pool for the study.
Their goal was to settle a debate about the "Ganzfeld"—a state of sensory deprivation intended to make the mind more receptive to extrasensory perception (ESP). The researchers wanted to know if the sensory blackout actually helped, or if it was a placebo. To do this, they built a "prototypical" successful experiment by averaging the details of 34 previous reports compiled by Schoutent in 1981. They created a control group: one set of subjects experienced the full Ganzfeld—red lights, headphones, white noise, and the ping-pong ball goggles—while the others simply sat in a chair.
They used a target pool of 80 images from National Geographic magazine, glued to white cardboard. To ensure the results weren't tainted by a crooked thumb on the scale, they used a Schmidt generator to randomize the targets. The lists of which images were selected were known only to the coordinator and a person identified as S.S., an external party granted exclusive access to the random lists.
The result was a void. The record states that using Stanford's Z-scores, "no difference between the Ganzfeld and the non-Ganzfeld conditions was found." Even the most hopeful post-hoc analyses yielded nothing. The record is blunt: "this study is to be counted as an unsuccessful replication."
Beating the Skeptics
The Utrecht team wasn't just chasing ghosts; they were chasing a methodology that could survive the scrutiny of the skeptics. The record explicitly notes that the researchers "tried to incorporate as much as possible the critique expressed by Hyman," a methodologist who had spent his career highlighting the flaws and procedural leaks in Ganzfeld research.
By designing the experiment to satisfy Hyman's demands, Schoutent and his team were attempting to build a "bulletproof" psi-test. If the experiment failed even when the gaps were plugged, it would suggest that the perceived successes of earlier Ganzfeld studies were products of sloppy science rather than actual paranormal ability.
This obsession with "psi-conduciveness"—the specific environmental conditions that allow a psychic signal to break through—was not unique to Utrecht. It mirrors the trajectory of Pavel Štěpánek, a Czech celebrity psychic who became the most tested individual in parapsychology during the 1960s. Štěpánek’s results were published in Nature in 1968, creating a gold standard for what a "successful" subject looked like. The Utrecht researchers were trying to find the environmental equivalent of a Štěpánek: a set of conditions that could reliably trigger the same results regardless of the subject.
The Intelligence Cut-Out
There is a glaring discrepancy between the nature of this record and its location. This is a failed academic exercise. The subjects were paid a pittance—15 guilders—and the results were a flatline. Yet, this paper was carefully archived by the CIA.
The desk's reading is that this represents a "cut-out" collection effort. The researchers at the University of Utrecht likely had no idea their work was being indexed by a foreign intelligence service. The CIA did not need to fund the study or plant a mole in the lab; they simply needed to harvest the results of an institution that was already doing the heavy lifting of methodological refinement.
If the shape of this file is what it appears to be, the agency wasn't collecting this paper because they believed in the Ganzfeld. They were collecting it as a manual of what not to do. During the same era, the U.S. government was pouring resources into its own remote viewing programs, attempting to turn psychic intuition into a weapon of Cold War espionage. To build a working system, you have to know exactly where the boundary of failure lies.
By archiving the Utrecht failure, the CIA was calibrating the boundaries of "psi-conduciveness." They were using the Dutch lab as a free laboratory to map the limits of the human mind. When the record says the Ganzfeld stimulation was "confusing" or "irritating" to the subjects, it isn't just a footnote about human comfort—it is a data point on how sensory deprivation affects the signal-to-noise ratio of a human target.
The Calibration of Silence
The record mentions "34 reports" from a 1981 Schouten overview that served as the blueprint for the experiment. Those reports are not in this release. The desk's reading is that the full file contained a comparative index of those 34 reports, which the agency used as a benchmark for "success" in paranormal research. They didn't want the Utrecht paper; they wanted the dataset that the paper was based on.
The pattern suggests that the CIA was using this specific, prototypical failure to refine the parameters of its own operational programs. By identifying the exact point where a "perfect" experiment failed, they could isolate the variables that actually mattered in their own remote viewing trials.
This is the irony of the Utrecht file: the researchers thought they were contributing to the "Ganzfeld debate" in a university setting. In reality, they were providing the negative space for a government program that viewed the human mind as a piece of hardware to be tuned. The 41 subjects who sat in the dark with ping-pong balls over their eyes weren't just failed psychics; they were the unwitting calibration tools for a spy agency's pursuit of the impossible. The still-withheld pages of these dossiers likely contain the agency's internal analysis of why the Utrecht study failed and how that failure proved the agency's own methods were superior. The subjects paid for that knowledge with their time and their dignity, receiving only 15 guilders for the privilege of being a data point in a secret ledger.
