Charles Richet: Experiments and Data

Charles Robert Richet (1850–1935) was a French physiologist who received the Nobel Prize in Physiology or Medicine (1913) for his work on anaphylaxis. He was simultaneously a sustained investigator of psychical phenomena across roughly six decades, and the sources retrieved for this question — primarily Alvarado ^[1], Evrard ^[2], Evrard et al. ^[3], and Alvarado & Evrard ^[4][5] — cover that dual career in considerable depth.

Research trajectory and institutional context

Richet’s engagement with psychical research began in the 1870s and ran through the early 1930s. Evrard ^[2] frames this as a deliberate, if sometimes strategically managed, parallel career: Richet pursued physiological psychology and psychical research alongside mainstream physiology, rather than abandoning the former for the latter. His 1922 Traité de métapsychique — an 800-page synthesis — was soon translated into several languages ^[2]. In its preface Richet stated he would write about facts without advancing a theory, distancing the work from spiritualism and theosophy ^[2].

He was a co-founder (with Xavier Dariex) of the Annales des Sciences Psychiques (1891–1919), the principal French journal for psychical research ^[4][5]. The journal’s development was assisted by Richet’s scientific prestige and by publisher Félix Alcan ^[4][5]. Beginning in June 1914, Richet organized monthly dinners with Henri Bergson, Eugène Osty, Camille Flammarion, Joseph Maxwell, Albert von Schrenck-Notzing, and others to discuss metapsychics ^[2][3]. In 1919 he accepted the honorary presidency of the Institut Métapsychique International, becoming president from 1929 ^[2].

Specific experimental subjects

Card studies and statistical analysis. Richet’s pupil Jean-Charles Roux conducted card studies; Richet himself analyzed them statistically in a note on chance and probability, published in the Annales (1893) ^[4][5]. The retrieved excerpts do not carry the specific hit rates or p-values from those analyses — the reader interested in the figures should consult the original 1893 note.

Eusapia Palladino. Richet investigated the Italian medium Palladino at length. Alvarado ^[1] translates an autobiographical essay in which Richet describes the sittings, including one image captioned “Controlling the medium (sitting Lombroso left and Richet right)” ^[1]. Richet’s essay describes her as “great and prodigious” and notes she was “scrutinized elsewhere in the most penetrating way by leading scholars, the most learned Italian physiologists, by Bottazzi, Foa, Herlitzka” ^[1]. The retrieved passages do not carry a tabulated summary of specific experimental outcomes from those sittings; what is present is Richet’s own retrospective account, translated by Alvarado.

Leonora Piper and Stefan Ossowiecki. Richet mentions Piper and Ossowiecki in the autobiographical essay, though Alvarado ^[1] notes a significant historiographic limitation: the essay does not supply the year or time period for any of these subjects, making it difficult to reconstruct a chronological sequence of investigations.

Mental suggestion (telepathy). Alvarado ^[4] references early work on mental suggestion at a distance published in the Annales, and cites Richet’s publication record in the journal on topics including lucidity and reason. Jean-Charles Roux’s 1893 card studies — and Richet’s statistical note on them — represent an early attempt to apply probability analysis to psi data in France ^[4][5].

Richet’s epistemological position

Richet coined the term métapsychique (metapsychics) as a proposed scientific discipline, distinct from spiritualism, that would study phenomena he described as not absolutely contradicting classic physics and physiology, despite their “enormous unlikelihood” ^[1]. Evrard ^[2] characterizes this framing as strategic: Richet was attempting to establish metapsychics as a legitimate field within French academic culture, seeking agreement on facts rather than advancing a spiritualist or survivalist theory. Evrard ^[2] also notes that Richet’s positioning was not without strategic aims — he sought to attract colleagues and to situate metapsychics within the broader development of psychological science.

Richet’s place in French intellectual networks

Alvarado and Evrard ^[4][5] and Evrard ^[2] together establish that Richet’s work was discussed in mainstream French intellectual publications, not only in specialized parapsychological journals. The Revue Philosophique de la France et de l’Étranger, a major philosophical journal, published discussions by Richet, Pierre Janet, and others on psychic phenomena. This is documented through Evrard’s broader analyses of those journals [as noted in the Evrard ESP-Nexus page].

Limitations of the autobiographical source

Alvarado ^[1] flags several historiographic problems with Richet’s own autobiographical essay as a data source:

• No chronological sequence is provided for key investigations (Palladino, Piper, Ossowiecki).
• The essay lacks the year or time period for major subjects.
• The same limitation applies to Richet’s Traité — not all readers will know when the relevant work was conducted.
• The essay reflects Richet’s retrospective self-presentation, which shapes what is included and what is omitted.

These are important cautions when treating the autobiographical record as experimental documentation.

Skeptical critiques

What critics argued. Richet was criticized both by individuals outside psychical research and — as Alvarado ^[1] notes — by some within it, though the retrieved excerpts do not name specific critics or their arguments in detail beyond this broad observation. The broader critical tradition pointed to the difficulty of ruling out fraud in physical-medium sittings of the Palladino type, given the conditions under which many investigations were conducted.

What the experimental data show. The retrieved sources do not carry a tabulated reanalysis or independent replication of Richet’s card or medium experiments from a skeptical standpoint. Rosemarie Pilkington, in a review cited in the ESP-Nexus pages, noted that a major survey of the psi field — covering more than 500 pages — contained no discussion of Richet, D. D. Home, Eusapia Palladino, or Sir William Crookes, treating the omission as a significant gap rather than as a verdict against the evidence [from the Pilkington pages].

Analysis. The experimental record Richet left is largely in French-language primary sources — the Annales, the Traité, and unpublished archival material. Systematic independent replication of his card-study protocols by researchers outside his immediate network has not been documented in the retrieved sources. The tension between his scientific standing (Nobel laureate) and his metapsychics work was managed by Richet through a deliberate rhetorical strategy of facts-without-theory, but that strategy did not fully insulate the work from criticism by contemporaries who regarded any sustained engagement with mediumship as credulous ^[1][2].
