Introduction

The GCP was motivated by prior PEAR research suggesting that RNG outputs could deviate from chance expectation in the presence of human intention. The central hypothesis is that during moments of “global coherence” in human consciousness—when millions focus on the same event—tiny but measurable correlations in RNG outputs may emerge worldwide.

Methodology

  • Hardware: Quantum-based RNGs using electronic noise or photon-based randomness sources.
  • Deployment: >70 RNG nodes across multiple continents, operating continuously and sending time-stamped data to a central server in Princeton, NJ.
  • Event Selection: Predetermined “global events” (e.g., September 11, 2001 attacks, New Year’s Eve, major sports finals) selected before analysis to minimize post hoc bias.
  • Statistical Tests: Compare cumulative deviation of standardized Z-scores from RNG network against null hypothesis of pure randomness.
  • Archiving: All data stored in public repositories for independent reanalysis.

Key Findings

  • Overall effect size: Across >500 preselected events (as of final PEAR-affiliated reports), cumulative deviation corresponded to p-values around 10⁻⁶ to 10⁻⁷, interpreted by proponents as extremely unlikely by chance alone [1].
  • Notable events:
    • 9/11 terrorist attacks – significant, sustained deviation beginning shortly before first impact.
    • New Year’s celebrations – consistent spikes across years.
    • Global meditation and prayer events – moderate but consistent deviations.
  • Time-lag effects: Some analyses report deviations beginning before the event time, suggesting possible retrocausal correlations (controversial even among proponents).

Critiques & Skeptical Reviews

  • Data selection bias: Critics argue “global events” may be chosen or excluded in ways that inflate significance.
  • Multiple testing: Some analyses do not fully account for the large number of possible statistical comparisons.
  • Physical plausibility: Skeptics note the absence of a well-supported mechanism for “consciousness fields” influencing RNGs at a distance.
  • Replication under controlled lab conditions: While small lab-scale mind–machine interaction studies exist, effect sizes are modest and not consistently replicable.

Assessment

The GCP remains one of the most ambitious field experiments in parapsychology, combining large datasets, global participation, and real-time monitoring. The persistent statistical deviations reported are intriguing but remain contested due to concerns about selection, statistical robustness, and lack of mechanistic grounding. Proponents view the results as suggestive evidence for a subtle, collective mind–matter interaction; skeptics see them as artifacts of statistical and methodological complexity.
