When Skeptics Deceive: Pseudo-Skepticism and the Case of Uri Geller

Published 2026-06-01 · 12 min read

Scepticism is a virtue of science — examining before judging. But there is a variety that does the opposite: it judges first and ridicules instead of examining. A co-founder of the world's largest sceptics' organisation gave it a name — "pseudo-scepticism" — and left the movement because he saw it drifting exactly there. This article asks the uncomfortable question: who examines the examiners?

The Witness from Within: Marcello Truzzi

The sociologist Marcello Truzzi co-founded CSICOP (today CSI), the most influential sceptics' organisation in the world, in 1976. He left it just a year later — with a sharp diagnosis: the group was not conducting open-ended examination but advocacy. It dismissed inconvenient claims in advance rather than investigating them. For this stance Truzzi coined the term "pseudo-sceptic": people who present themselves as sober examiners but are in truth deniers — they assert a negative verdict without carrying the burden of proof that any claim entails.

Truzzi also flagged the misuse of the famous line "extraordinary claims require extraordinary evidence". Properly understood, it is a call for care. Misused as a weapon it becomes immunisation: the bar is set arbitrarily high for the other side and arbitrarily low for one's own debunking.

The Asymmetry of the Burden of Proof

This names the real mechanism. In public debate a double bookkeeping is common:

  • The claim of a phenomenon is examined strictly, often with hostility — rightly so.
  • The debunking, however, is usually believed unexamined. A sceptic presents an "exposure video", an alternative explanation, a trick — and the case is considered closed. Yet a debunking is itself a claim. It too can be wrong, selective or staged.

Why of all things should the debunking material be exempt from examination? Whoever demands extraordinary evidence for extraordinary claims must demand extraordinary care of the debunkings too. This is exactly where pseudo-scepticism fails — and exactly where the Uri Geller case lies.

The Case of Uri Geller

Uri Geller became world-famous in the 1970s — and remains the favourite target of organised debunking to this day. The popular story runs: "long since exposed as a trickster". The evidence is more layered.

At the Stanford Research Institute, the physicists Russell Targ and Harold Puthoff studied Geller under laboratory conditions. Part of this work — experiments in which Geller reproduced drawings inside a shielded room — appeared in Nature in 1974, one of the most prestigious scientific journals there is. Nature printed the article with an unusually critical editorial note, but: it was a peer-reviewed paper, not an esoteric pamphlet. The same line of research — later above all with Ingo Swann and Pat Price — was significant enough that US intelligence services maintained state-funded programmes on "extrasensory perception" for over two decades, later known as Stargate.

And the famous "exposure"? In 1973 Geller appeared on Johnny Carson's Tonight Show; Carson, a former stage magician, supplied his own controlled props — and Geller "did not deliver". Sceptics read this as proof of trickery. Yet two things usually go unsaid: first, the appearance made Geller more famous in the short term (in his own words: "That show made Uri Geller"); the clip became "proof of his failure" only through decades of repetition. Second — and decisively — a single evening on stage, success or failure, is not an experiment. The actual data lie in the laboratory, not the studio. That the popular debate ranks the studio above the laboratory is the asymmetry in its purest form.

And one thing is rarely mentioned: even among magicians there is no consensus. While professional sceptics like James Randi declared everything standard trickery, other experienced mentalists openly admitted they could not explain certain of his effects — the moving compass needle, for instance. The popular "a magician can replicate it" argument thus cuts both ways: that an effect can be produced with tricks does not prove the original was a trick — and some experts did not even get that far.

What This Does Not Mean

Here honesty is a duty, otherwise the critique flips into its own mirror image. That pseudo-scepticism exists proves no paranormal powers. The SRI experiments also drew substantive scientific criticism — for instance about possible sensory leakage and procedural questions — and that comes not from stage magicians but is legitimate methodological debate. The Geller case is therefore not "proven genuine" but contested: remarkable findings, published in Nature, that were pushed out of serious discourse rather than cleanly refuted.

The demand of this article is therefore modest and fair: the same standards for both sides. A debunking is no free pass; it is a claim like any other and deserves the same examination as the thing it sets out to debunk.

When Scepticism Becomes Pseudo-Scepticism

This is where the line lies. The neurologist Prof. Wilfried Kuhn puts it bluntly: if you have one piece of evidence for near-death experiences, the sceptic demands ten; if you have ten, he demands a hundred; if you have a hundred, he demands a thousand. To ask for evidence is legitimate — but when the demand doubles with every piece supplied and can be satisfied by nothing, it no longer examines anything; it merely immunises one's own verdict. That is the tipping point: not the asking for evidence, but the structural impossibility of ever having enough.

This pattern is not new. Relativity and quantum physics were held at arm's length for decades with ever-new objections, until the weight of the evidence was simply overwhelming. At some point reason reverses: when the findings accumulate and the only answer is "more proof", it becomes wiser to think pro than contra. Even well-meaning sceptics often miss this moment — they mistake caution for refusal.

Why This Is Here

For the themes of this site this is central. Again and again, inconvenient findings — on near-death experiences, mediumship or physical mediumship — are pushed out of the discourse not by data but by ridicule. That this ridiculing rather than refuting is no accident but a long-rehearsed tone is shown in the piece on Voltaire's mocking school tone — how a posture of scorn toward the mystical became an academic standard. How a mere majority or authority can be wrong is shown in Majority versus Experts; the social forces behind it are described in herd behaviour, and the psychological defence patterns in The Psychology of Skeptical Defence. And it is worth asking who benefits: Mediumship and Power shows that mediumistic phenomena can become inconvenient for those in power — and are pushed back with the very means this site describes elsewhere: with propaganda, with public ridicule by pseudo-sceptics, and through the education system. Doubt in itself is not the virtue; open-ended examination is. Pseudo-scepticism is its opposite in the costume of science — a verdict that no evidence can any longer shake. The difference comes down to a single question: is someone really examining — or have they already judged?
