Experiments

The sources retrieved for this question do not document Michael Grosso as the primary designer or conductor of controlled laboratory experiments in the conventional parapsychological sense — no randomized trials, ganzfeld sessions, or forced-choice card studies appear under his name in the retrieved material. His investigative work is instead concentrated in two other modes:

Historical and case investigation. Grosso conducted sustained scholarly investigation into the documented phenomena surrounding St. Joseph of Copertino, the 17th-century Franciscan friar associated with reported levitation. This work drew on sworn depositions, ecclesiastical records, and eyewitness testimony compiled across decades, producing a detailed case study in what Grosso treats as evidence bearing on survival and macro-physical anomalies ^[3]. He cites, for example, a sworn deposition from a Brother Francesco attesting to what the deponent described as Joseph’s apparent telepathic cognition ^[3].

Critical review and theoretical synthesis. A significant portion of his published output consists of scholarly book reviews and essay reviews in peer-reviewed journals — Journal of Scientific Exploration and Journal of Near-Death Studies — engaging empirically and philosophically with survival literature, near-death research, altered states, possession, mediumship, and consciousness studies ^{[1][2][3][4][5][6]}. These are not passive summaries; Grosso uses them as vehicles for theoretical argument and critical assessment of the evidence base.

Methodology

Because Grosso’s primary mode of inquiry is historical-documentary and philosophical rather than experimental, the methodological questions are different from those that apply to laboratory researchers.

Historical case methodology. For the St. Joseph investigation, Grosso’s approach was to compile, translate, and critically assess primary-source ecclesiastical and legal documents — sworn depositions, formal beatification records, and biographical accounts — treating them analogously to witness testimony in legal or historical scholarship ^[3]. He flagged the epistemically relevant question of witness motivation and corroboration (distinguishing, for example, curiosity visitors from serious deponents) ^[3].

Critical review methodology. In his essay reviews, Grosso applies a consistent evaluative framework: he examines whether a work adequately weighs alternative explanations (including the hypothesis that apparent survival evidence could be accounted for by the psi capacities of living persons), whether empirical claims are overstated beyond what data support, and whether philosophical commitments are doing unacknowledged evidential work ^[1][2][5]. He has explicitly flagged the conflation of empirical evidence for post-mortem consciousness survival with claims about inherent immortality as a recurring methodological error in the literature he reviews.

Data

No structured quantitative evidence — effect sizes, hit rates, z-scores, p-values — is present in the sources retrieved for this question, which is consistent with Grosso’s mode of scholarship. His work does not generate trial-level data of the kind that would be tabulated.

What the sources do record are his analytical positions functioning as qualitative findings:

• Near-death research has demonstrable value in shifting cultural attitudes toward death, but empirical NDE data cannot be straightforwardly extended to claims about inherent deathlessness ^[2].
• Survival literature systematically under-weights the “living-agent psi” alternative — the possibility that apparent evidence of post-mortem communication reflects the anomalous capacities of living percipients rather than discarnate agency ^[1].
• Historical testimony regarding anomalous physical phenomena (in the Copertino case) meets standards of sworn, corroborated witness documentation that Grosso argues deserve serious rather than dismissive treatment ^[3].
• Altered states of consciousness — as documented in ancient Greek culture by Ustinova and reviewed by Grosso — have historically been recognized as sources of supernormal cognition and creativity, a pattern Grosso finds relevant to contemporary parapsychology ^[1].

The retrieved excerpts do not contain quantitative outcome data; readers seeking any numerical findings should go directly to the cited primary sources.

Skeptical critiques

The sources retrieved for this question do not include published criticism of Grosso’s work by a named critic with a citable publication. The retrieved material consists entirely of his own published reviews and correspondence, with no reanalysis, methodological objection, or rebuttal by a named external author present in the excerpts.
