Dean I. Radin, PhD is profiled on ESP-Nexus at Dean I. Radin, PhD. The question about his lab at UNLV touches a specific period in his career — the mid-1990s — that the ESP-Nexus page addresses directly.

Before summarizing what the sources show, a necessary qualification on scope: the studies currently in the ESP-Nexus library represent a sample of the published literature on Radin’s work, and the library’s share of that total literature has not been measured. Treat what follows as a summary of what the library holds, not a settled account of the field. The chart below plots a subset of standardized effect sizes against publication year for studies on a single comparable metric.

Experiments

The ESP-Nexus page records a 1996 multivariate study conducted at UNLV as the flagship work from that period. It used four psi tests — a circle of lights, duck herding, a robot arm, and video clips — administered to 96 participants tracked over a full year. A separate, earlier effort described on the same page tracked 49 environmental, physiological, and cosmic variables simultaneously with mind-matter interaction (MMI) performance over 65 days, identifying 44 statistically significant correlations versus 26 expected by chance.

The sources retrieved for this question do not include papers from the UNLV period itself — the numbered sources cover Radin’s more recent IONS-based work (Global Consciousness Project analyses, a water pH replication study, and related lines). The UNLV lab details come from the ESP-Nexus scientist page rather than from a primary paper retrieved here.

Methodology

The UNLV multivariate study’s design is notable for its ambition: rather than testing a single psi modality, it ran four distinct protocols on the same participant pool across a year, enabling within-subject comparisons and longitudinal tracking. The analysis then applied a neural network trained on 8 predictors derived from 24 psychological, environmental, and demographic variables to predict individual psi performance in held-out participants — an approach oriented toward identifying moderating variables rather than simply estimating a mean effect. The 65-day MMI study similarly used multivariate environmental tracking and a neural network, reporting a held-out predictive correlation of r = 0.405.

This represents a methodological stance Radin has maintained across his career: treating psi performance as a variable phenomenon whose variance is worth modeling, rather than assuming a fixed underlying effect size.

The retrieved numbered sources for this question cover different protocols — GCP random-number-generator analyses and a water-chemistry replication — so detailed protocol information for the UNLV experiments is not in the retrieved primary literature.

Data

For the UNLV multivariate study specifically, the ESP-Nexus page reports that the four individual psi tests showed null results, while the neural network trained on the combined predictor set predicted held-out participant performance. No individual-test effect sizes or p-values for the UNLV study are present in the retrieved numbered sources, so those figures cannot be stated here.

The broader evidence table rendered below this answer covers 66 studies and 81 result rows from across Radin’s career. The metrics are heterogeneous — z-scores, hit rates, Cohen’s d, correlations, and p-only results — and must not be averaged or pooled into a single summary figure. The evidence set includes:

• Several positive results at p <.001 or stronger, across GCP analyses, double-slit optical MMI, and other lines
• 9 null or below-chance results in the full set, including at least one study where individual experimental sessions ran below chance
• A Wahbeh et al. (2021) result showing null overall performance on a quick remote viewing task
• An Alibalaei et al. (2025) study with a null precognition result (Cohen’s d = −0.027, p =.783)

Reported directions disagree across studies — this is an explicitly unsettled signal in the evidence base, not a minor qualification.

Skeptical critiques

The numbered sources retrieved for this question — covering recent GCP and water-chemistry work — do not include published criticism directed specifically at the UNLV lab or its multivariate methodology. The ESP-Nexus scientist page for Radin carries a skeptical critiques section; readers looking for the critical exchange around his work are directed there: Dean I. Radin, PhD.
