Psi Research Has a Replication Problem — But It's Not the One You Think


The skeptic's standard move against parapsychology is simple: nothing replicates. It's a clean kill shot. Except it's not quite accurate anymore, and the field's own researchers are doing the most interesting work sorting out which parts of it hold.

The clearest recent evidence on this comes from a 2025 paper by Etzel Cardeña, summarized in a Substack review of current psi literature: "The only paradigm that seems to have had mostly lack of or at best mixed recent replications is that of precognitive priming." That's a significant concession — precognitive priming was one of the field's most-discussed experimental paradigms after Daryl Bem's "Feeling the Future" studies generated enormous controversy. But Cardeña's broader conclusion is that "overall experimental work across time and research paradigms has continued to support the reality of psi phenomena."

So the picture is more granular than either side usually admits. Some paradigms are failing replication. Others aren't. That's actually how a maturing research field is supposed to behave.

What makes this moment interesting is that psi researchers are increasingly turning the methodological lens on themselves. A 2024 study from the University of Virginia's Division of Perceptual Studies, published in Frontiers in Psychology, examined cognitive styles across four groups: academic psi researchers, lay psi believers, academic skeptics, and lay skeptics. The finding was counterintuitive — psi researchers scored more similarly to skeptics than to lay believers on measures of actively open-minded thinking and need for closure. In other words, the people running the experiments don't think like the people who want the experiments to confirm their priors.

That matters for the replication question. One persistent critique of positive psi results is that they're produced by motivated researchers with poor controls. The UVA data complicates that story. It doesn't prove psi is real, but it does suggest the field's active researchers are applying more critical scrutiny than the "true believer" caricature allows.

The British Psychological Society's exchange between Chris Roe and Chris French — two researchers on opposite sides — captures where the methodological debate actually lives. French points to replication failures as decisive. Roe points to the cumulative meta-analytic record across paradigms. Neither is obviously wrong. The honest position is that some effects are robust enough to survive meta-analysis, some aren't, and the field needs better pre-registration and adversarial collaboration to sort which is which.

That's the real methodological advance happening right now — not a breakthrough result, but a more honest accounting of what's holding up and what isn't. For a field that spent decades defending its legitimacy against blanket dismissal, that kind of internal rigor is the more durable win.
