Why Did Scientific Witnesses Trust Polish Mediums?

Introduction

Why did intelligent, scientifically minded observers trust Polish mediums in the early twentieth century? The short answer is that many séance demonstrations appeared to combine modern investigation with striking physical effects. Cameras were present, respected psychologists and physicians took notes, and experiments were described in scientific language. Yet the controls were often weaker than they seemed. Darkness concealed crucial actions, investigators sometimes accepted suspicious phenomena rather than eliminating them, and skilled performers could exploit small gaps in supervision. The careers of Stanisława Tomczyk and Franek Kluski show how apparently scientific séances could produce impressive evidence while still leaving opportunities for deception. Their stories became some of the most famous examples in Poland’s history of psychical research and remain cautionary tales about the difference between observing something unusual and proving a paranormal explanation.[Wikipedia]WikipediaStanisława TomczykStanisława Tomczyk

Stanisława Tomczyk and the Visible Thread

Stanisława Tomczyk became one of the best-known Polish mediums of the period through claims that she could move objects without touching them. The psychologist Julian Ochorowicz conducted lengthy investigations of her in southern Poland between 1908 and 1909. Small objects such as balls, scissors and matchboxes appeared to move or levitate while her hands hovered nearby. Ochorowicz believed these effects revealed a previously unknown force and developed elaborate theories about invisible emanations produced by the medium.[wikipedia.org]WikipediaStanisława TomczykStanisława Tomczyk

The problem was that the experiments repeatedly produced a more ordinary explanation. Investigators sometimes noticed what appeared to be a fine thread or hair between Tomczyk’s hands. Ochorowicz himself reported seeing such a thread but interpreted it as a paranormal substance rather than evidence of trickery. Other observers were less convinced. The Swiss psychologist Théodore Flournoy reported failed demonstrations and concluded that some attempted effects were plainly fraudulent. Another investigator, Professor Batelli, suspected that object movements were produced with a concealed thread.[Wikipedia]WikipediaStanisława TomczykStanisława Tomczyk

The strongest challenge came from professional conjurors. Magicians recognised that a thin black thread, especially under poor lighting conditions, could create exactly the sort of apparent levitations reported in séances. William S. Marriott successfully reproduced one of Tomczyk’s celebrated feats—the levitation of a glass beaker—using ordinary stage methods involving hidden thread. What psychical researchers interpreted as evidence of unknown forces could therefore be recreated without invoking the paranormal.[Wikipedia]WikipediaStanisława TomczykStanisława Tomczyk

This does not mean every witness was dishonest. Many investigators genuinely believed they were observing something extraordinary. The lesson is that they often treated anomalies as evidence for a new force before fully excluding simpler explanations. In modern experimental terms, the controls were not robust enough to distinguish between a genuine phenomenon and a skilled performance.[Wikipedia]WikipediaStanisława TomczykStanisława Tomczyk

Franek Kluski and the Paraffin Spirit Moulds

If Tomczyk’s levitations impressed observers, Franek Kluski’s wax spirit hands seemed even harder to explain. Kluski, whose real name was Teofil Modrzejewski, became famous for séances in which supposedly materialised spirits dipped their hands into warm paraffin wax and cold water, leaving hollow moulds behind. Researchers argued that some moulds appeared anatomically difficult to produce using ordinary human hands. Because the wax casts were physical objects that could be examined after the séance, they seemed stronger evidence than fleeting visual impressions.[wikipedia.org]WikipediaFranek KluskiFranek Kluski

Supporters regarded the moulds as scientific evidence. Investigators measured them, weighed them and preserved them in collections. The involvement of prominent psychical researchers helped create an impression of rigorous testing. To believers, the casts looked like tangible proof that invisible entities had briefly taken physical form.[Psi Encyclopedia]psi-encyclopedia.spr.ac.ukPsi Encyclopedia Franek KluskiPsi EncyclopediaFranek Kluski - Psi Encyclopedia28 May 2018 — Paraffin gloves were said to form within minutes, and coloured wax and weig…Published: May 2018

Sceptics focused on a simpler question: could the moulds be made by normal means? Magicians quickly showed that they could. Carlos María de Heredia demonstrated methods using rubber gloves, paraffin and cold water. Harry Houdini later reproduced similar moulds using only his own hands and hot paraffin, showing that supposedly impossible casts did not require supernatural intervention. Modern investigators including Massimo Polidoro and chemist Luigi Garlaschelli have also recreated moulds resembling Kluski’s examples through entirely conventional techniques.[wikipedia.org]WikipediaFranek KluskiFranek Kluski

The debate never entirely disappeared because supporters argued that some séance conditions made fraud difficult. Yet critics pointed out that darkness, limited observation and the possibility of prepared materials left too many opportunities for deception. Harry Price complained that no major scientific body had independently subjected Kluski’s alleged powers to genuinely rigorous examination. Reports also circulated among psychical researchers alleging that fraud had been detected.[Wikipedia]WikipediaFranek KluskiFranek Kluski

How Darkness, Photography and Weak Controls Misled Investigators

The common thread linking these Polish mediumship cases was not merely belief in spirits. It was confidence that scientific observation was taking place.

Many séance organisers adopted the language and tools of science:

However, the crucial controls often remained inadequate. Physical mediums typically insisted on dim red light or complete darkness. Observers could not continuously verify where hands, feet or hidden objects were located. A thread, wire, prepared mould or sleight-of-hand movement became much harder to detect under such conditions. The apparent scientific framework could therefore create a false sense of security.[Wikipedia]WikipediaStanisława TomczykStanisława Tomczyk

Photography created a similar problem. Early psychical researchers treated photographs as objective records, yet cameras merely recorded what was placed before them. Ochorowicz interpreted unusual photographic effects around Tomczyk as evidence of previously unknown energies. Later critics argued that the images reflected experimental flaws and photographic manipulation rather than new discoveries about nature. Scientific institutions that initially rewarded some of the work later rejected the claims.[Wikipedia]WikipediaStanisława TomczykStanisława Tomczyk

Another weakness was investigator bias. Researchers who hoped to discover proof of psychic forces sometimes interpreted suspicious details as part of the phenomenon itself. The thread seen around Tomczyk became, in Ochorowicz’s view, a mysterious substance rather than a warning sign. This reversal of normal sceptical procedure allowed potentially fraudulent evidence to be reclassified as confirmation.[Wikipedia]WikipediaStanisława TomczykStanisława Tomczyk

What These Seances Reveal About Belief and Evidence

The stories of Tomczyk and Kluski occupy a distinctive place in Poland’s history of contested truth because they were not crude confidence tricks aimed at extracting money from the public. They emerged at a moment when psychology, hypnotism, photography and psychical research were all developing rapidly. Many participants sincerely believed they were exploring unknown aspects of nature.[ParapsychologyPress]parapsychologypress.orgJP-83-1-(69-78) | ParapsychologyPressThe purpose of this paper is to present the contribution of Julian Ochorowicz to…

Their importance today lies in how they illustrate a recurring problem in the history of science and pseudoscience. Scientific-looking procedures can increase credibility without necessarily increasing reliability. A respected observer, a camera, a laboratory setting or a technical vocabulary may persuade audiences that extraordinary claims have been properly tested. Yet if controls are weak, those same features can make an illusion appear more convincing rather than less.

In the end, ordinary conjuring methods explained the key phenomena more economically than theories of psychic force or spirit materialisation. The visible thread behind Tomczyk’s levitations and the reproducible techniques behind Kluski’s wax hands remain among the clearest examples of how scientific séances could generate impressive evidence while still failing the basic test of excluding deception.[Wikipedia]WikipediaStanisława TomczykStanisława Tomczyk
