Is Biological Death Final? Recomputing the Drake-S Equation for Postmortem Survival of Consciousness

This participatory team science project extended Laythe and Houran’s (2022) prior application of a famous probabilistic argument known as the ‘Drake equation’ to the question of postmortem survival. Specifically, we evaluated effect sizes from peer-reviewed, empirical studies to determine the maximum average percentage effect that ostensibly supports (i.e., anomalous effects ) or refutes (i.e., known confounds ) the survival hypothesis. But unlike the earlier application, this research included a study-specific estimate of the hypothesized variable of ‘living agent psi’ via a new meta-analysis of empirical studies (N = 17) with exceptional subjects vs participants from the general population. Our updated analysis found that putative psi was a meaningful variable, although it along with other known confounds still did not account for 30.3% of survival-related phenomena that appear to attest directly to human consciousness continuing after physical (biological) death. Thus, the popular conventional variables that we measured here are seemingly insufficient to account for a sizable portion of the purported empirical data that has been interpreted as evidence of survival. Our conclusion is nonetheless tempered by several assumptions and limitations of our speculative exercise, which ultimately does not affirm the existence of an ‘afterlife’ but rather highlights the need for measurements with greater precision and/ or a more comprehensive set of quantifiable variables. Therefore, we discuss how our probabilistic approach provides important heuristics to guide future research in this highly controversial domain that touches both parapsychology and transpersonal psychology

Quantifying The Phenomenology Of Ghostly Episodes: PART I – Need For A Standard Operationalisation

We review conceptualizations and measurements of base (or core) experiences commonly attributed to haunts and poltergeists (i.e., “ghostly episodes”). Case analyses, surveys, controlled experiments, and field studies have attempted to gauge anomalous experiences in this domain, albeit with methods that do not cumulatively build on earlier research. Although most approaches agree, to an extent, on the base experiences or events that witnesses report, the literature lacks a standard operationalization that can be used to test the factor structure of these occurrences or allow meaningful comparisons of findings across studies. Towards filling this gap, our review and deliberation identified 28 base experiences that include subjective (or psychological) experiences more typical of haunts, and objective (or physical) manifestations more common to poltergeist-like disturbances. This qualitatively-vetted list is proposed as the foundation for new measurement approaches, research designs, and analytical methods aimed to advance model-building and theory-formation

Dead Reckoning: A Multiteam System Approach to Commentaries on the Drake-S Equation for Survival

We used a multiteam system approach (MTS) to map the critical and constructive feedback from four invited Commentaries on Rock et al.’s (2023) probabilistic analysis of purported evidence for postmortem survival. The goal was to mine actionable insights to guide future research with the potential for important learnings or breakthroughs about the nature or limits of human consciousness and their relation to transpersonal psychology. The commentators’ input identified only a few measurable variables or empirical tactics that conceivably challenge or refine our latest Drake-S Equation for survival. However, a review of these suggestions using logical and statistical criteria revealed that none immediately upend our previous conclusion that the published effect sizes for various Known Confounds (including hypothetical living agent psi ) do not fully account for the published prevalence rates of Anomalous Experiences traditionally interpretated as survival. However, the commentators proposed several good recommendations for new studies that could eventually alter this calculus. Accordingly, we outline the architecture of a proposed cross-disciplinary research program that extends the present MTS approach and its collected insights and focuses strictly on empiricism over rhetoric in this domain. The results of this coordinated effort should likewise help to clarify a range of psychological and biomedical phenomena that speak to the nature and limits of human consciousness

Conceptual and clinical implications of a “Haunted People Syndrome”.

Evidence suggests that subjective and objective anomalies associated with ghostlyepisodes form a unidimensional Rasch scale and that these interconnected“signs orsymptoms”arguably describe a syndrome model. This view predicts that symptomperception—that is, the phenomenology of these anomalous episodes—can be markedlyskewed by an experient’s psychological set. This is impacted, in turn, by psychosocialvariables that affect attentional, perceptual, and interpretational processes. Therefore, wepresent an overview that discusses how (a) Belief in the Paranormal, (b) ReligiousIdeology, (c) Ideological Practice, (d) Social Desirability, (e) Latency, and (f) Environ-mental Setting ostensibly influence the contents or interpretations of accounts. Theseexperiential details are similarly expected to reveal insights into the psychodynamicsbeing expressed or contextualized via these narratives. Future research in this area shouldhelp to validate and clarify the proposed syndrome model, as well as explore whichnuances in the phenomenology of ghostly episodes reflect idiosyncrasies of experients’psychological set versus the nature of the core phenomenon itself

Follow-up on the U.S. Central Intelligence Agency's (CIA) remote viewing experiments

Objectives: Since 1972, the U.S. Central Intelligence Agency (CIA) commissioned several research programs on remote viewing (RV) that were progressively declassified from 1995 to 2003. The main objectives of this research were to statistically replicate the original findings and address the question: What are the underlying cognitive mechanisms involved in RV? The research focused on emotional intelligence (EI) theory and intuitive information processing as possible hypothetical mechanisms. Methods: We used a quasi-experimental design with new statistical control techniques based on structural equation modeling, analysis of invariance, and forced-choice experiments to accurately objectify results. We measured emotional intelligence with the Mayer—Salovey–Caruso Emotional Intelligence Test. A total of 347 participants who were nonbelievers in psychic experiences completed an RV experiment using targets based on location coordinates. A total of 287 participants reported beliefs in psychic experiences and completed another RV experiment using targets based on images of places. Moreover, we divided the total sample into further subsamples for the purpose of replicating the findings and also used different thresholds on standard deviations to test for variation in effect sizes. The hit rates on the psi-RV task were contrasted with the estimated chance. Results: The results of our first group analysis were nonsignificant, but the analysis applied to the second group produced significant RV-related effects corresponding to the positive influence of EI (i.e., hits in the RV experiments were 19.5% predicted from EI) with small to moderate effect sizes (between 0. 457 and 0.853). Conclusions: These findings have profound implications for a new hypothesis of anomalous cognitions relative to RV protocols. Emotions perceived during RV sessions may play an important role in the production of anomalous cognitions. We propose the Production-Identification-Comprehension (PIC) emotional model as a function of behavior that could enhance VR test success

Haunted people syndrome revisited: empirical parallels between subjective paranormal episodes and group-stalking accounts

Research suggests a Haunted People Syndrome (HP-S) is defined by the recurrent perception of anomalous subjective and objective events. Occurrences are traditionally attributed to supernatural agencies, but we argue that such interpretations have morphed into themes of “surveillance and stalking” in group-stalking reports. We tested a series of related hypotheses by re-analyzing survey data from the 2015 Sheridan and James study to explore statistical patterns in “delusional” group-stalking accounts (N=128) versus“non-delusional” (control) accounts of lone-culprit stalking (N=128). As expected, we found that (i) account types had different Rasch hierachies, (ii) the Rasch hierarchy of group-stalking experiences showed a robust unidimensional model, and (iii) this group-stalking hierarchy correlated significantly with spontanous “ghost“ experiences. However, we found no clear evidence for “event clustering” that might signify contagious processes in symptom perception. Findings support the viability of the HP-S construct and the idea that experiences of group-stalking and haunts share common sources
