Overview

When Brenda Dunne arrived at Princeton in 1979 to establish the PEAR laboratory, remote viewing research existed in a methodological limbo. The Stanford Research Institute’s pioneering work had generated intriguing results, but the field lacked standardized protocols and transparent analytical procedures that could withstand scientific scrutiny. Dunne’s background in developmental psychology and her experience conducting remote viewing studies in Chicago positioned her uniquely to address this gap. She did not approach remote viewing as an engineer seeking to build machines, nor as a parapsychologist defending a controversial claim, but as a developmental psychologist interested in how human consciousness might interact with information systems.

Over the next 28 years, Dunne designed and managed PEAR’s remote viewing program, which became one of the longest-running and most extensively documented investigations of anomalous cognition. Her contributions extended beyond experimental management to include methodological innovation, statistical analysis, and the articulation of theoretical frameworks that contextualized the empirical findings. The protocols she developed established benchmarks for rigor that influenced how remote viewing research was conducted internationally.

Early remote viewing studies

Dunne’s entry into remote viewing research predated her arrival at Princeton. In the late 1970s, she conducted a replication of the Stanford remote viewing protocol in the Chicago area, working with J. P. Bisaha. This study was significant not merely as a replication but as a demonstration that remote viewing effects could be reproduced in a different laboratory setting by independent researchers. The Chicago experiment confirmed precognitive remote perception (the ability to describe a target location before it was selected) using the same basic methodology that had yielded positive results at Stanford.²

Dunne and Bisaha also conducted long-distance precognitive remote viewing experiments, extending the geographical scope of the phenomenon.⁶ These early studies established her reputation as a careful experimentalist capable of executing complex protocols and interpreting ambiguous data. When Robert Jahn, then dean of Princeton’s engineering school, sought someone to design and manage his proposed anomalies laboratory, Dunne’s track record made her the natural choice. Her appointment in 1979 marked the beginning of the most productive phase of her research career.

PEAR protocols and refinement

The PEAR laboratory’s remote viewing program built upon the Stanford methodology but introduced significant refinements. Dunne worked closely with Robert Jahn and other colleagues to develop protocols that addressed methodological concerns raised by skeptics and that allowed for more sophisticated statistical analysis. One of her key innovations was the introduction of structured descriptor systems that transformed subjective impressions into quantifiable data.

In 1980, Dunne and Jahn published their foundational work on analytical judging procedures for remote perception experiments.⁷ This paper established formal criteria for evaluating the correspondence between a remote viewer’s transcript and the actual target. Rather than relying on informal impressions of similarity, the analytical judging procedure provided explicit rules for scoring matches. This methodological advance was crucial because it reduced experimenter bias and allowed independent judges to evaluate transcripts without knowing which target they corresponded to.

Building on this foundation, Dunne, Jahn, and colleagues developed an even more sophisticated system: ternary coding and generalized descriptors.¹ This system allowed judges to classify elements of remote viewing transcripts into three categories (present, absent, or uncertain) rather than forcing binary judgments. The use of generalized descriptors (such as “geometric,” “organic,” “human-made”) enabled consistent evaluation across diverse target types. These innovations transformed remote viewing data into a format suitable for rigorous statistical analysis while preserving the qualitative richness of the transcripts.

The PEAR team’s commitment to methodological transparency meant that all protocols, judging criteria, and analytical procedures were documented in technical reports and published papers. This openness allowed other researchers to replicate PEAR’s methods and to scrutinize the analytical framework. The precognitive remote perception protocol, refined over multiple iterations, became the standard approach used in PEAR’s remote viewing research throughout the 1980s and 1990s.⁸

Analytical and judging procedures

Dunne’s most enduring contribution to remote viewing methodology was her development of systematic analytical frameworks. The challenge in remote viewing research is that transcripts are inherently subjective and multifaceted. A single transcript might contain accurate impressions mixed with inaccurate ones, metaphorical descriptions alongside literal ones, and information that is vague enough to match multiple targets. Without clear analytical rules, evaluating transcripts becomes an exercise in pattern-finding that can easily be biased by experimenter expectations.

Dunne addressed this challenge by creating hierarchical judging systems. The ternary coding approach allowed judges to make finer distinctions than simple hit/miss judgments. By coding elements as present, absent, or uncertain, the system captured the actual state of the judge’s assessment rather than forcing artificial binary choices. This approach reduced the likelihood that ambiguous matches would be counted as hits and that marginal misses would be overlooked.¹

The generalized descriptor system complemented ternary coding by establishing categories that applied across different target types. A remote viewer might describe a target location as having “geometric structures” and “human-made elements.” These descriptors could be evaluated consistently whether the target was an urban plaza, an industrial facility, or an architectural landmark. By standardizing the vocabulary of evaluation, Dunne’s system reduced the subjective interpretation that had plagued earlier remote viewing research.

These analytical procedures were not merely technical innovations; they represented a philosophical commitment to transparency and reproducibility. By making the judging process explicit and rule-based, Dunne created a framework that could be audited, criticized, and improved. Other researchers could examine the judging criteria and either accept them or propose alternatives. This openness to scrutiny strengthened rather than weakened the credibility of PEAR’s findings.

Information and uncertainty in remote viewing research

As PEAR’s remote viewing program accumulated data over decades, Dunne and Jahn began to address a deeper question: what does statistical significance mean in the context of remote viewing? A study might show that remote viewers performed better than chance, but how much information did they actually transmit? How should researchers interpret the relationship between statistical significance and practical information content?

In their 2003 paper on information and uncertainty in remote perception research, Dunne and Jahn examined this question using PEAR’s 25-year database.⁵ They analyzed the relationship between effect sizes, information transmission rates, and the uncertainty inherent in remote viewing tasks. This work moved beyond simple significance testing to ask whether the anomalous effects observed in remote viewing experiments represented meaningful information transfer or merely statistical fluctuations.

The analysis revealed that remote viewing effects, while statistically significant across large datasets, typically transmitted modest amounts of information per trial. A remote viewer might achieve 55% accuracy on binary target discrimination tasks, which is statistically significant over thousands of trials but represents only a small deviation from the 50% expected by chance. Dunne and colleagues contextualized this finding by noting that even small information transmission rates, when consistent across many trials, constitute genuine anomalous effects worthy of scientific investigation.³

This nuanced treatment of information and uncertainty distinguished PEAR’s approach from both uncritical acceptance of remote viewing claims and dismissive skepticism. Dunne acknowledged that remote viewing effects, if real, were subtle and probabilistic rather than dramatic and deterministic. This realistic assessment actually strengthened the credibility of the research by avoiding exaggerated claims while maintaining confidence in the statistical findings.

Legacy and ongoing influence

Dunne’s remote viewing protocols and analytical methods became foundational to the modern anomalies research field. The ternary coding system and generalized descriptors she developed were adopted by other laboratories conducting remote viewing research. Her emphasis on transparent, rule-based judging procedures influenced how subsequent researchers approached the challenge of evaluating qualitative data in parapsychology.

The PEAR remote viewing database, which Dunne helped build and analyze over 25 years, remains one of the largest and most thoroughly documented collections of remote viewing data in existence. Researchers continue to cite PEAR’s protocols and findings when designing their own remote viewing studies or when reviewing the state of the field. The analytical frameworks Dunne developed provide a model for how to transform subjective phenomena into quantifiable research domains without losing the richness of the original observations.

Beyond the specific methodologies, Dunne’s approach to remote viewing research exemplified a broader commitment to scientific rigor in parapsychology. She demonstrated that anomalies research could be conducted with the same attention to protocol design, analytical transparency, and statistical sophistication as any mainstream scientific field. Her work helped establish that skepticism about parapsychology need not mean dismissal of the research; instead, it could motivate more careful methodology and more honest assessment of findings.

When the PEAR laboratory closed in 2007, Dunne and Jahn transitioned their work to the International Consciousness Research Laboratories (ICRL), which Dunne had co-founded in 1990. ICRL continued to sponsor remote viewing research and to publish analyses of the PEAR data. Dunne remained active in this work until her death in 2022, ensuring that the protocols and insights she had developed over decades remained available to the research community.
