Debra Lynne Katz, PhD is a parapsychology researcher, remote viewing practitioner, and founder of the International School of Clairvoyance, profiled at Debra Lynne Katz. Her work spans experimental studies of associative remote viewing (ARV), meta-analytic synthesis of the remote viewing literature, and methodological writing on how psi research should be designed and taught. She has served as president of the International Remote Viewing Association (IRVA) and co-founded the IRVA Research Unit in 2020 with Dale Graff. Career affiliations include the California Institute for Human Sciences, the University of West Georgia, and IRVA.

Before summarizing the quantitative record: the library’s share of the published literature on Katz’s research has not been measured, so what follows reflects the studies currently held in the ESP-Nexus library, not a settled account of the field. Two result rows are available, carrying different and non-comparable metrics.

Experiments

Background context in photographic targets (2021). Katz, together with James D. Lane (Rhine Research Center) and Michelle Freed-Bulgatz, ran a controlled remote viewing study examining whether the background context surrounding objects in photographic targets affects viewer performance. The study-audit page is at Katz et al. (2021). This is an experimental design asking whether a specific target property — the richness or distinctiveness of background context — modulates ARV accuracy.

Project Firefly (2018). Katz ran a naturalistic predictive study — Project Firefly — in which participants made daily aggregate predictions over approximately two months (October 20, 2014 – December 18, 2015). This study tested whether remote viewers could predict future targets under an applied, real-world-style protocol.

Remote Viewing meta-analysis (2023). Katz co-authored, with Patrizio Tressoldi (Science of Consciousness Research Group, University of Padua), the first systematic review and meta-analysis of the remote viewing literature spanning 1974–2022, published in the Journal of Scientific Exploration. This is a quantitative synthesis rather than a primary experiment, but it represents a major research contribution: aggregating and re-analyzing decades of published studies under a single statistical framework.

Sensing accuracy survey (2026). With Jimmy Akin and Jenifer Prather, Katz published a survey study examining experienced remote viewers’ awareness of their own correctness — whether viewers can detect when they are “on target” — in the Journal of Anomalous Experience and Cognition. The study draws on self-report and connects to prior research on confidence judgments in mediumship and forced-choice psi experiments.

Experts’ remote viewing guidelines (2026). With Akin and Tressoldi, Katz contributed to a qualitative expert-consensus paper synthesizing guidelines for designing remote viewing research — covering viewer selection, analytical methods, and procedural standards.

Teaching replication and critical thinking (2025). With Jeffrey S. Reber (University of West Georgia), Jacob H. Tengelsen, and Peder Schillemat, Katz co-authored an analysis of how introductory psychology textbooks handle replication, using a sample of thirty studies to assess how replication status is — or is not — communicated to students.

Methodology

Katz et al. (2021) used a within-subjects repeated-measures design. Targets were photographic images varying by background context (a manipulated property of the target stimuli). The primary analysis was a repeated-measures ANOVA (RM-ANOVA) on sum-of-ranks scores across background conditions, run across 360 trials with 12 participants. The study was structured to isolate a specific target variable — background context — rather than testing remote viewing ability overall, which makes it a hypothesis-driven experimental design rather than an exploratory demonstration.

Project Firefly (2018) used a naturalistic prediction protocol: 62 participants generated 177 daily aggregate predictions. This is a lower-control design than a laboratory study — the ecological conditions are closer to applied ARV use, but controls over participant selection, blinding, and judging are correspondingly harder to enforce. The outcome metric was hit rate against chance.

The 2023 meta-analysis applied systematic review methods to the 1974–2022 remote viewing literature, using a random-effects meta-analytic model and examining moderators including type of participant, type of task, publication type, and an interaction term. Katz’s co-author Tressoldi is listed as contributing Conceptualization and Methodology; Katz contributed Writing and Project Administration. The paper explicitly flags that Katz’s affiliation with IRVA — an organization that promotes remote viewing — is a relevant conflict of interest to note when interpreting the synthesis.

The 2026 guidelines paper used thematic analysis (Braun & Clarke, 2006) to synthesize expert opinions, following a qualitative methodology. Katz contributed to writing and project administration. A notable methodological recommendation Katz articulated: experienced viewers should be recruited unless the study specifically requires naïve participants, and viewers should be permitted to use whichever methods they are most comfortable with rather than being constrained to a single procedure.

Data

The ESP-Nexus library holds two quantitative result rows for Katz’s experiments. These rows use different, non-comparable metrics and must not be pooled.

The two studies point in different directions. Katz et al. (2021) reports a statistically significant background-condition main effect (p =.01) on sum-of-ranks scores across 360 trials. Project Firefly returns a hit rate of 0.48 against an implied chance baseline, with a raw effect size of −0.02 — a null result, marginally below chance rather than above it.

These two studies test different things (a controlled target-variable manipulation vs. a naturalistic daily prediction task), involve different participant counts, and use different outcome metrics — so no pooled figure is meaningful. The UNSETTLED SIGNALS in the library are genuine: the studies disagree in direction, and one reports a null-to-below-chance result.

The 2023 meta-analysis and the 2026 papers do not contribute quantitative rows to the structured evidence block for this query; the retrieved excerpts do not contain the meta-analysis’s pooled effect sizes in a form that can be attributed unambiguously, so those figures are not reported here — readers should consult the published paper directly at doi:10.31275/20232931.

Skeptical critiques

What critics argue. No published critique of this work appears in the sources retrieved for this question.

What the experimental data show. The two primary experimental rows in the library show a mixed picture: a significant positive result in the controlled laboratory study (Katz et al., 2021, p =.01, N = 360 trials) and a null result in the naturalistic Project Firefly study (hit rate 0.48, ES = −0.02, N = 177 trials). Neither result resolves the conflict-of-interest question, which is a structural property of the meta-analysis authorship rather than a property of any single experiment’s outcome.

Analysis. The conflict-of-interest flag raised on the study-audit page is the principal critical engagement surfaced by the sources retrieved for this question. It is specific to the meta-analysis rather than to Katz’s experimental work.
