Psychokinesis

Imagine a small metal vane balanced delicately on a needle inside a clear case. You stare at it intently, willing it to spin with nothing but the power of your mind.

Sometimes… it actually moves.

For decades, devices like this — commonly called psi wheels or torsion pendulums — have been used as simple demonstrations of alleged psychokinesis, the ability to influence physical objects through mental intention alone. These sensitive toys have convinced many people that they possess real “mind over matter” powers.

But is that what’s really happening?

Psychokinesis (PK), often called “mind on matter,” refers to the parapsychological claim that mental intention alone can influence physical systems. Telekinesis — the ability to move objects without physical contact — is usually presented as a dramatic subset of PK.

For decades, these ideas have captured public imagination through movies like Carrie and Stranger Things, where characters effortlessly bend reality with their minds. But what does the actual research show?

Serious scientific investigation of psychokinesis began in earnest in the 1960s with physicist Helmut Schmidt. He used electronic random number generators (RNGs) to test whether human intention could subtly bias random outputs. Schmidt reported small but statistically significant deviations from chance and published them in peer-reviewed journals.

From 1979 to 2007, the Princeton Engineering Anomalies Research (PEAR) Laboratory, directed by Robert G. Jahn, ran some of the most ambitious micro-PK studies. Researchers accumulated millions of trials with Random Event Generators (REGs). They reported tiny but “consistent” deviations correlated with operator intention.

Effect sizes were extremely small — on the order of a 0.1% shift from chance. One operator reportedly contributed a disproportionate share of the results. The lab published technical reports and papers, but faced ongoing criticism for methodological weaknesses, poor controls, and statistical issues. Independent attempts to replicate PEAR’s findings, including a multi-lab consortium using the same equipment and protocols, largely failed to produce significant results. The lab closed in 2007 without gaining mainstream scientific acceptance.

Dean Radin has continued this line of work, conducting micro-PK experiments and publishing meta-analyses that claim overall statistically significant cumulative effects across studies. He argues that the effect sizes are comparable to small but accepted findings in psychology. However, these meta-analyses have been criticized for potential publication bias, the “file-drawer” problem (where negative results go unreported), and the tendency for effects to shrink or vanish when stricter controls and pre-registration are applied. High-powered, independent replications have often failed to confirm the original claims.

Despite decades of effort, psychokinesis research faces the same core challenges:

Mainstream science classifies telekinesis and broader psychokinesis claims as pseudoscience, primarily due to these replicability and theoretical problems.

Public fascination with psychokinesis often stems from charismatic demonstrators rather than lab data.

Uri Geller rose to fame in the 1970s with television demonstrations of spoon bending and “mind-powered” watch stopping. Magician and skeptic James Randi repeatedly replicated these effects using stage magic techniques. When Geller appeared on The Tonight Show with Johnny Carson (who consulted Randi on controls), he was unable to perform under proper conditions and offered excuses instead.

During the Cold War, Soviet psychic Nina Kulagina was filmed apparently moving small objects without contact. However, multiple investigations — including by Soviet scientists and journalists — raised serious concerns about fraud. Accusations included the use of concealed threads, magnets, or sleight-of-hand. Soviet publications like Pravda publicly accused her of trickery, and the demonstrations lacked the rigorous, double-blind controls needed to rule out normal explanations.

One of the most instructive (and overlooked) aspects of psychokinesis claims involves simple demonstration devices popular in the 20th century: lightweight psi wheels (folded paper or foil balanced on a pin), suspended needles under glass, torsion pendulums, and sealed indicators.

These devices are extraordinarily sensitive. They can rotate from minor air currents, convection caused by body heat, static electricity, small vibrations, or even infrared radiation from a nearby hand warming the air. Demonstrators and enthusiasts have repeatedly shown that a psi wheel can spin without any “mind power” simply from the heat of a hand placed nearby.

When environmental controls are lax, it becomes very easy to misinterpret ordinary thermodynamic and airflow effects as evidence of telekinesis. As the saying goes, it is far easier to fool a person than to convince them they have been fooled.

Psychological factors play a major role. Confirmation bias leads people to notice and remember apparent “hits” while downplaying misses or normal explanations. Pop culture reinforces the idea that such abilities are possible — or even suppressed by mainstream science.

Occam’s razor remains useful here: when faced with extraordinary claims and ordinary explanations (stage magic, subtle physical forces, statistical artifacts, or expectation effects), the simplest sufficient explanation is usually the correct one.

After more than half a century of laboratory efforts and countless dramatic demonstrations, psychokinesis has not produced robust, independently replicable evidence that would convince the broader scientific community.

Helmut Schmidt, Robert Jahn, and Dean Radin have tested PK in laboratory settings and detected statistically significant results that cannot be explained away. These results evoke criticism of the techniques used or the math from mainstream science.

Organizations like the Rhine Research Center and the Parapsychological Association continue to study these phenomena, which is fine as exploratory work.
