Montague Ullman, MD

Montague Ullman, MD was a psychiatrist and parapsychologist who founded the Maimonides Medical Center Dream Laboratory and built the first sustained laboratory program for testing telepathy during sleep. His core contribution was methodological: he brought polysomnography, blind judging, and statistical analysis into dream-psi research at a time when the field had no such infrastructure. The overview below draws on the sources retrieved for this question plus the ESP-Nexus profile at Montague Ullman, MD.

Experiments

The central line of work was the Maimonides dream-telepathy series, conducted with Stanley Krippner. The 1966 confirmatory study ^[1] is representative of the program’s structure: a single receiver slept in the laboratory while an agent in a separate room concentrated on a randomly selected target image; the receiver was awakened during REM periods and asked to report dream content; those reports were then rated against the target and decoys.

The series extended across multiple studies testing different questions:

• Basic telepathy transmission — whether dream content corresponded to a target image an agent was viewing ^[1]
• Precognitive dream studies — whether dream content anticipated future target material, probing whether psi might operate across a temporal boundary
• Art-print transmission experiments — above-chance hit rates comparing receiver narratives to target and decoy images under controlled sleep conditions

Charles Honorton worked within this program at Maimonides before later directing the Psychophysical Research Laboratories, and his subsequent ganzfeld work grew in part from methodological lessons he absorbed in Ullman’s laboratory. The 1973 book Dream Telepathy (Ullman, Krippner, and Alan Vaughan) synthesized the program’s findings for a broader audience.

Methodology

The Maimonides protocol combined several interlocking controls:

• Polysomnographic monitoring — continuous EEG recording allowed experimenters to identify REM sleep objectively and time awakenings to the phase most associated with vivid dreaming
• Physical separation — receiver and agent were in rooms isolated from one another; communication during the session was not possible
• Blind judging — dream transcripts and target materials were rated by judges who had not witnessed the session; the rating procedure used structured matrices comparing transcripts against both the correct target and decoy images
• Statistical analysis via analysis of variance — transcript-target combinations were entered into matrices and tested with ANOVA, using the Scheffé technique for post-hoc comparisons ^[1]

A specific methodological challenge Ullman’s team addressed directly was the allegation that significant results could be obtained simply by matching any transcript to any target through post-hoc pattern recognition. The 1966 study included “control” combinations — randomly assembled transcript-target pairings — as an internal check on that objection ^[1].

Ullman’s theoretical rationale held that REM sleep creates neurophysiological conditions distinctively receptive to anomalous information transfer, treating the dreaming brain as a signal-reception state rather than a noise source.

Data

The retrieved excerpts carry several concrete figures from the 1966 confirmatory study ^[1]:

The null result on control combinations is directly relevant: it addresses the allegation that dreams are so symbolically rich that any transcript will appear to match any target. The control analysis did not produce significant results, and the authors flag this explicitly ^[1].

The retrieved excerpts do not include the full numerical record for the precognitive dream studies or the broader art-print series; those figures exist in the primary literature but are not present in what was retrieved here. The ESP-Nexus profile notes that art-print transmission experiments produced above-chance hit rates, and that precognitive studies identified instances of apparent temporal correspondence, but specific statistics for those lines should be traced to the primary papers rather than to this summary.

Skeptical critiques

What critics argue. The most persistent methodological objection across the Maimonides series concerned the richness and ambiguity of dream content: because dreams naturally produce varied symbolic material, blind judges rating transcripts against images might find correspondences spuriously, and significant ANOVA results might reflect this matching flexibility rather than any anomalous information transfer. This concern — sometimes framed as a “multiple endpoints” problem or a critic of the judging procedure — was live enough that Ullman’s team incorporated the control-combination analysis directly into the 1966 study design ^[1]. The sources retrieved for this question do not include a named critic’s published paper making this argument in its full form; the objection is recorded within Ullman and Krippner’s own paper as an objection they were responding to ^[1].

What the experimental data show. The 1966 study’s internal check — constructing control transcript-target matrices from randomly assembled pairings — produced a non-significant F of −0.71, while the correct pairings produced F = 8.11 at p < 0.01 ^[1]. The confirmatory ANOVA across the seven-night experiment yielded F = 6.43 at p < 0.001 ^[1]. These results distinguish the correct pairings from chance combinations under the same judging procedure.

Analysis. The specific question of whether blind judging of dream content against art-print targets can be made artifact-free — independent of the original laboratory team and with pre-registered judging criteria — has not been resolved by a fully independent replication series outside the Maimonides group, based on what the sources retrieved for this question contain. Charles Honorton’s later shift to the ganzfeld paradigm, with waking receivers and more tractable forced-choice judgments, partly reflects the methodological difficulty of exporting the Maimonides dream protocol to other sites.
