Stanisława Tomczyk’s psychokinesis tests

Record summary

Stanisława Tomczyk was a Polish medium investigated by Julian Ochorowicz, who reported that she could influence small objects and produce movements under séance conditions. Accounts describe experiments involving glass vessels, scales, and other apparatus, sometimes attributing the effects to an invisible personality called “Little Stasia.” The lead matters for comparing early psychical research, dissociation, apparatus design, and the boundary between occult narrative and experimental claim. The evidence is contested, with critics proposing concealed threads or other mechanical means and questioning the adequacy of controls.
