Scientists Have Spent Decades Testing Psychic Phenomena; Their Results Were Systematically Buried

Parapsychology has a cultural reputation for fraud and wishful thinking. What it also has is 50+ years of peer-reviewed research, consistent replicated effects, and almost no institutional support for finding out what produces them.
For most of recorded scientific history, migratory birds did something that seemed impossible. Twice a year, species like the American robin navigated thousands of miles with precision that instruments could track but could not explain. How did these birds know where to go year after year, following the same routes and in many cases, making the journey without any parental or peer guidance?
The eventual answer was quantum. Cryptochrome proteins in the avian retina interact with Earth's magnetic field through a process called the radical pair mechanism, quantum chemistry operating inside a living eye, at body temperature, in real time. For decades, that answer had been considered impossible. The assumption posited by Erwin Schrödinger in the 1940s was that quantum effects couldn't survive in "warm, wet, and noisy" biological systems. That assumption turned out to be wrong.
Before spending time working on social cognition at Yale, I studied raptor migration at Hawk Mountain Sanctuary and migration ecology at the Center for Conservation Biology at William & Mary. The gap between a behavior that is clearly observed and a mechanism that hasn't been found yet is something scientists become familiar with early in their careers. That gap, and an argument for closing it, is the core focus of this piece.
Magnetoreception was not an isolated case. Apparent quantum coherence in photosynthesis, the process that allows green plants and bacteria to convert light energy into chemical energy with near-perfect efficiency, was also considered impossible on the same grounds. (The precise nature of that contribution is still being worked out.) So was proton tunneling in enzyme catalysis, which allows biochemical reactions to bypass classical energy barriers and proceed much more quickly than previously thought possible. Quantum mechanisms for all three of these biological processes are now supported by peer-reviewed research (Figure 1).

The pattern runs consistently: the behavior was real all along, but the explanatory framework hadn't caught up.
The Data
In parapsychology research, the umbrella term for anomalous information transfer, perception that can't be explained by known mechanisms, is psi. Its subtypes include:
remote viewing (perceiving information about a spatially inaccessible place or event),
precognition (perceiving information about a future event before it occurs),
telepathy (perceiving information from another person's mind), and
presentiment (unconscious physiological anticipation of a future stimulus, or the body-level form of precognition).
(In research contexts, these perceptual subtypes are often grouped under the term “anomalous cognition”.)
In the 1970s, physicists Russell Targ and Harold Puthoff conducted remote viewing studies at Stanford Research Institute (SRI). Their findings were published in Nature and in Proceedings of the IEEE, both mainstream peer-reviewed journals. The CIA's Stargate Project, which ran from the 1970s through 1995, was built in part on that laboratory foundation. An independent government review of Stargate acknowledged statistically significant results while recommending the program be closed.
In 2023, Tressoldi and Katz published the first comprehensive meta-analysis of 50 years of remote viewing research in the Journal of Scientific Exploration, a specialist peer-reviewed journal dedicated to anomalous phenomena research. Across 36 studies and 40 effect sizes, the authors found a statistically significant effect size of .34 (95% CI: .22-.45), approximately 19.3% above chance performance. The analysis specifically tested for publication bias, the tendency for positive results to be published while null results stay in file drawers, and found minimal evidence of it.
An effect size of .34 is modest (Figure 2). However, it is worth noting that the effect size for aspirin reducing heart attack risk is .03, a finding considered sufficient to halt a major clinical trial early and adopt aspirin as standard preventive care. Effect size alone is not the standard by which evidence is dismissed.

The ganzfeld protocol (Figure 3), a sensory-reduction technique designed to quiet ordinary perceptual processing and test for telepathic transmission, has been studied at over a dozen independent laboratories. Across 59 studies, subjects consistently identified a target image at a rate of approximately 30% against a 25% chance baseline, a result replicated across four independent meta-analyses.

Presentiment research, most associated with Dean Radin at the University of Nevada, measures physiological responses, including skin conductance, heart rate, pupil dilation, and brain activity measured by electroencephalogram (EEG). The research indicates that these responses precede randomly selected emotionally significant stimuli by 2-3 seconds. The effect is small. It has also been replicated across multiple laboratories using multiple methodologies, with meta-analyses showing probability against chance that runs into the billions.
These findings are not conclusive; the honest state of the evidence is mixed. Daryl Bem's 2011 paper in the Journal of Personality and Social Psychology, which reported statistical evidence for precognition across nine experiments and more than 1,000 participants, generated both significant interest and significant controversy. A 2023 pre-registered replication by Kekecs and a large international team, designed with Bem's input and published in Royal Society Open Science, found no effect.
Replication failures in this literature are common. They are also not unique to this literature.
The Physics
The most common objection to precognition as a phenomenon is that it is physically impossible. That objection rests on a specific model of time, one that physics itself no longer uniformly endorses.
Classical physics gave us a linear clock: past causes present, present causes future, and the arrow of time runs in one direction. Einstein's relativity broke the strict universality of that model: time moves at different rates depending on mass and velocity. This is empirically confirmed, not theoretical.
Quantum mechanics complicated our understanding of time even further. Entangled particles demonstrate correlations that cannot be explained by classical physics, and those correlations are not constrained to space. Experiments have demonstrated photon entanglement that operates across time, before the second particle formally exists.
Cambridge philosopher Huw Price has argued in published, peer-reviewed work, also cited in the Stanford Encyclopedia of Philosophy, that a genuinely time-symmetric interpretation of quantum mechanics would require some form of backward causation as a natural feature, not a violation. The block universe model, in which past, present, and future coexist as a four-dimensional structure rather than a moving present moment, is a mainstream interpretation in physics, not a marginal one.
None of this proves precognition. It does mean the objection rests on a model of time that mainstream physics no longer uniformly accepts.
Why the Record Is So Thin
Given more than 50 years of research producing consistent if modest effects, the relevant question is why we don't know more about the nature and mechanisms of psi. The answer seems to be structural.
A controlled study gave researchers two versions of the same abstract. The abstracts described the same methodology, data, and findings. One was labeled as a neuroscience study, whereas the other was labeled a parapsychology study. The “parapsychology” abstract was rated as less valid, less reliable, and having weaker findings, despite the underlying data being identical.
Skeptical bias operates in science the same way confirmation bias does, shaping what gets funded, submitted, published, and replicated. The demand for a higher evidentiary standard applied asymmetrically to one research area is itself a bias worth naming.
A survey of Parapsychological Association members found that the primary barriers to research in the field were not negative results but structural limitations: no career path, limited journal access, no funding. No funding produces small samples. Small samples produce statistical vulnerability. Statistical vulnerability produces dismissal. Dismissal produces no funding. Consciousness research broadly faces a comparable funding gap, even outside parapsychology (Figure 4).

The cost of that cycle has precedent. For decades, psychedelic research was functionally frozen, not because early findings were negative, but because cultural and political stigma made investigation professionally dangerous. When stigma partially lifted, the field moved quickly:
FDA Breakthrough Therapy designation for psilocybin in treatment-resistant depression in 2018
FDA Breakthrough Therapy designation for LSD in generalized anxiety disorder in 2024
Entire therapeutic categories were invisible for generations. The cost was paid by patients who needed treatment options that weren't available yet.
A comparable structural failure preceded the inclusion of women in clinical research. Prior to the NIH Revitalization Act of 1993, women were routinely excluded from clinical trials. The rationale was hormonal cycle variability, which was treated as a complication rather than medically relevant data. The result was decades of dosing standards, drug interactions, and diagnostic criteria built on male physiology. Cardiology, pharmacology, and pain medicine are still correcting for it. (For a deep dive on this topic, I recommend Caroline Criado Pérez's Invisible Women.)
Individual Variation and the Question of Development
The research does not suggest that psi capacity, if it exists, is uniformly distributed across the population. The Tressoldi and Katz meta-analysis found a meaningful performance difference between participants pre-screened for psi ability and the general population, a pattern more consistent with a trait or trainable skill than a universal constant.
The Controlled Remote Viewing (CRV) protocol, developed at SRI by researcher Ingo Swann, is a structured, step-by-step methodology in which trained viewers learn to separate signal from mental noise through a sequence of perceptual stages, moving from raw sensory impressions to more detailed analysis of a target. It was designed explicitly as a trainable system rather than a talent-dependent one, and selected participants trained in the protocol consistently outperformed untrained controls in laboratory settings.
A 2024 study by Mossbridge and colleagues examined whether emotional state affects remote viewing accuracy. In one of two experiments, participants who reported calm engagement and high interest in the target performed significantly better; the second experiment did not replicate the finding. The result is preliminary and mixed, but it raises the question of whether internal state is as relevant to psi performance as the external protocol.
The meditation literature points in a similar direction. A study by Penberthy and colleagues at the University of Virginia's Division of Perceptual Studies found that a meditation group reported significantly more frequent paranormal experiences than a non-meditating control group at both pre- and post-test, and that mindfulness levels were positively associated with those experiences throughout the study period.
An important distinction: the Penberthy trial found increases in reported experience, not in measured psi task performance. That may reflect genuine measurement limits in the experimental tasks rather than absence of effect. It may also indicate that the effect is primarily experiential.
What neuroimaging confirms is that long-term meditators show measurable structural and functional changes to the default mode network (DMN). The DMN is the brain system associated with self-referential thought and what researchers sometimes call “mental time travel”, the cognitive process of projecting oneself into past or future scenarios (Figure 5). These changes persist outside active meditation, indicating durable trait-level shifts rather than temporary states.
[datawidget key="fig-5"]
Across remote viewing, ganzfeld, and presentiment research, performance is consistently higher when ordinary perceptual processing is quieted. The ganzfeld protocol specifically induces mild sensory reduction as its operating condition. Whether meditation works through a mechanistically similar pathway, and whether the DMN alterations in long-term meditators represent something relevant to anomalous cognition, are open questions. They are also the questions a funded, rigorous research program would be positioned to examine.
What Comes Next
What would it actually take to find out whether the signal is real?
That question has rarely been seriously asked, in part because the structural conditions described earlier have made a genuine answer feel academic. No funding, no career path, no institutional stability: the research that exists has been produced almost entirely around those constraints rather than through any coordinated effort to remove them. What follows is what a research program operating without those constraints might actually pursue.
The DMN connection is the most tractable near-term lead. Long-term meditators show measurable, persistent structural changes to the brain regions associated with self-referential thought and mental time travel, and those same conditions appear consistently across the protocols producing the strongest psi results. Quieted default-mode processing is the common thread running through ganzfeld design, remote viewing performance, and presentiment detection. The research that would actually clarify this: longitudinal neuroimaging studies comparing meditators and non-meditators on standardized psi tasks over time, with DMN activity tracked across both meditation sessions and task performance. This is standard cognitive neuroscience methodology applied to an unstudied question.
The quantum biology frame opens a second direction. The radical pair mechanism in avian magnetoreception was confirmed through a specific logic: identify the biological structure, characterize the quantum process, test whether the effect disappears under conditions that should disrupt quantum coherence. The same logic could apply to anomalous cognition. The prior assumption was that there was no biological substrate worth looking for. That assumption is now worth revisiting, not because psi is confirmed but because what scientists once classified as impossible inside living biological systems has been substantially revised over the last two decades.
A third direction follows from the individual variation data. A small subset of participants consistently drives most of the effects in this literature. Neurological and psychological profiling of high-performing remote viewers, the people who produce reliable results across multiple protocols and independent labs, has not been done at any meaningful scale. Understanding what distinguishes them would either narrow the mechanism search considerably or clarify whether the effects are psychometric artifacts.
Seventy miles from Richmond, the University of Virginia's Division of Perceptual Studies (DOPS) has been doing this work for more than 60 years. Founded by psychiatrist Ian Stevenson in 1967, DOPS is one of the few academic units in the world with the institutional continuity and methodological credibility to pursue anomalous cognition research in a way that withstands scientific scrutiny. Their work spans near-death experience research, past-life memory studies in children, and the meditation trial cited earlier in this piece. DOPS is a functioning research division at a major research university producing careful, peer-reviewed work on questions the broader field has largely declined to ask.
What DOPS represents is the proof of concept: that serious, sustained inquiry into this territory is possible within an academic institution, with proper methodology, without professional collapse. The obstacle has never been the absence of a model. It has been the absence of the infrastructure to replicate it.
The migratory birds were doing something real for a very long time before anyone could explain how. The behavior preceded our discovery of the mechanism by decades. The quantum explanation, once it was uncovered, required revising assumptions that had seemed foundational: that quantum effects couldn't persist in warm biological systems; that living tissue was too "noisy" an environment for physics at that scale.
Those assumptions were not unreasonable given what physics knew at the time. And yet, they were wrong.
Science advances by finding out where it was wrong. The psi research record does not offer proof, but it does offer something that serious inquiry requires: a consistent, replicated signal that the existing framework doesn't account for. What that signal points to, we don't yet know. What it points away from is the idea that continued investigation isn't worth pursuing.
