Meta-Analysis of a Complete Micro-PK Database from the LMU Lab: Efforts for Maximum Transparency in Publishing Results

Despite robust meta-analytical evidence, research on psi phenomena consistently struggles to convince skeptics of the underlying effects (e.g., Reber & Alcock, 2020). A primary criticism centers on selective publication, suggesting a large “file drawer” where numerous experimental failures remain unpublished (Rothstein et al., 2005). Open Science practices, such as preregistration, have been proposed as countermeasures. However, these strategies have limitations, as some datasets originate from pilot studies, student research projects, or other non-preregistered sources and thus remain unpublished.

The Lab Report – A Transparency Initiative

To address this issue, we have established an online website that provides a continuously updated overview of all micro-PK experiments conducted at our lab at LMU Munich (https://mrzdcmps.github.io/labreport/ ). Micro-PK refers to the hypothesized ability of mental influence on inanimate probabilistic systems, such as random number generators (Varvoglis & Bancel, 2015). This initiative aims to enhance transparency and reproducibility by making all relevant experimental results available in a comprehensive and accessible manner (Dechamps, 2024). Importantly, the website is solely dedicated to studies conducted within our lab and does not serve as an open platform for external researchers to post their results.

The database includes all studies investigating a general micro-PK effect, including pilot studies, while excluding case studies of individuals and research on related psi phenomena such as precognition. For each study, the platform provides a concise summary detailing the hypothesis, sample characteristics, materials, and procedure. Additionally, raw data and supplementary materials (e.g., questionnaires, analysis scripts, experimental programs) are made available for direct download. Where studies feature multiple conditions (e.g., experimental vs. control), details for all conditions are provided.

An aggregated study overview presents key statistical parameters such as p-values and Bayes Factors. A distinguishing feature of the lab report is the inclusion of “change of evidence” parameters. These measures track the temporal development of Bayesian evidence throughout data collection and compare observed patterns to an empirical null distribution generated through simulations. These analyses, explained in detail within the report, offer deeper insights into the dynamics of statistical evidence accumulation.

Instead of a traditional peer-review process, we encourage community engagement via the http://Hypothes.is platform, allowing researchers to provide open feedback and contribute to a transparent, interactive dialogue on the results and methodologies.

Moritz Dechamps has been a researcher at LMU Munich since 2015, dedicated to exploring the fundamental questions of reality and human interaction with it. His academic journey has been deeply rooted in the study of parapsychological phenomena, including a 2019 dissertation on mind-matter interactions and their replicability. His research spans topics such as anomalous cognition and perturbation, consciousness, free will, intuition, expectancy effects, and self-fulfilling prophecies.

The Parapsychological Association is an international professional organization of scientists and scholars engaged in the study of psi (or ‘psychic’) experiences, such as telepathy, clairvoyance, psychokinesis, psychic healing, and precognition. The primary objective of the PA is to achieve a scientific understanding of these experiences.
