Introduction

One of the central methodological issues raised by David Marks and Richard Kammann was not simply whether remote viewers produced accurate descriptions, but how those descriptions were evaluated. Unlike a multiple-choice test, remote-viewing experiments typically generated open-ended transcripts containing sketches, impressions, metaphors and isolated words. The final judgement depended on deciding which target best matched this collection of fragments. Marks and Kammann argued that this combination of free-response descriptions and flexible interpretation created opportunities for ordinary psychological processes to produce apparently impressive matches without requiring paranormal perception.[SciSpace]scispace.cominformation transmission in remote viewing experiments 4jd6pdendvIN a recent Jetter to Nature 1 Marks and.

Their critique focused on the judging process rather than the sincerity of participants. If a transcript contains broad statements that could plausibly describe many locations, and if judges are allowed considerable freedom in deciding what counts as a “match”, the risk increases that hindsight and subjective interpretation will inflate apparent success. This mechanism became an important part of the wider debate over the early Stanford Research Institute (SRI) remote-viewing experiments.[SciSpace]scispace.cominformation transmission in remote viewing experiments 4jd6pdendvIN a recent Jetter to Nature 1 Marks and.

How Free-Response Transcripts Differ from Fixed Answers

Remote-viewing protocols were deliberately designed as free-response tasks. Instead of asking participants to identify one correct option from a small list, viewers were encouraged to report every impression that came to mind. A typical transcript might contain:

  • rough sketches
  • references to shapes or textures
  • emotional impressions
  • comparisons such as “bridge-like” or “industrial”
  • isolated words such as “water”, “metal”, “tower” or “round”

This approach was intended to avoid some of the limitations of earlier forced-choice extrasensory perception experiments, where participants repeatedly guessed symbols or cards. Supporters argued that genuine anomalous perception might emerge more naturally through unrestricted description than through artificial multiple-choice testing.[Psi Encyclopedia]psi-encyclopedia.spr.ac.ukPsi Encyclopedia Remote ViewingPsi EncyclopediaRemote Viewing - Psi Encyclopedia13 Jan 2017 — Remote viewing replaced repetitive forced-choice tasks with free-response…

The consequence, however, is that evaluation becomes much more subjective. Rather than asking whether a single answer is correct, judges must decide how well an entire collection of partial observations corresponds to one target compared with several alternatives.

Why Broad Phrases Fit Many Targets

Marks and Kammann’s concern was that many remote-viewing descriptions were highly general. Statements such as:

  • “there is water nearby”
  • “I sense a large structure”
  • “something circular”
  • “an open area”
  • “metal or concrete”

could reasonably apply to numerous locations.

This does not mean the descriptions were meaningless. Rather, their interpretive flexibility increases the number of possible successful pairings. A harbour may contain water, but so may a reservoir, fountain or riverside park. A “large structure” might refer to a bridge, office building, stadium or factory.

Once the true target is known, readers naturally focus on the similarities while discounting details that do not fit. Psychologists describe this as a form of retrospective pattern matching: after learning the answer, ambiguous statements often appear much more specific than they seemed beforehand. Marks and Kammann argued that this tendency could contribute substantially to apparently successful remote-viewing judgements.[SciSpace]scispace.cominformation transmission in remote viewing experiments 4jd6pdendvIN a recent Jetter to Nature 1 Marks and.

Flexible Matching and Hindsight Interpretation

The criticism becomes stronger when free-response descriptions are combined with flexible judging procedures.

Imagine a transcript containing twenty separate observations. Some will almost certainly fail to describe the intended target, while others may resemble features found at several possible sites. If judges are free to emphasise the successful fragments while treating incorrect statements as unimportant, an overall impression of accuracy may emerge even when no individual statement uniquely identifies the target.

This process differs fundamentally from objective scoring. In a conventional test, an answer is either correct or incorrect. In free-response remote viewing, the decision often becomes one of degree:

  • How important is each statement?
  • Which similarities deserve the greatest weight?
  • How much mismatch is acceptable?
  • Should symbolic or metaphorical statements count?

Different judges can legitimately answer these questions differently, making reliability more difficult to establish. This concern formed part of Marks and Kammann’s broader argument that apparently striking correspondences might arise through interpretation rather than information transfer alone.[SciSpace]scispace.cominformation transmission in remote viewing experiments 4jd6pdendvIN a recent Jetter to Nature 1 Marks and. Kammann offer criticism of the SRI experiments in 'remote viewing', the…

Why This Matters for Blind Judging

The problem is magnified if judges possess any additional information beyond the transcript itself.

Marks and Kammann argued that even subtle procedural clues—such as references to previous sessions, dates or target order—could combine with broad descriptions to make the correct pairing appear much easier than intended. Because the descriptive material was already open to multiple interpretations, any extra contextual information could steer judges towards one target while reinforcing confidence that the match reflected paranormal accuracy rather than inference.[SciSpace]scispace.cominformation transmission in remote viewing experiments 4jd6pdendvIN a recent Jetter to Nature 1 Marks and. Kammann offer criticism of the SRI experiments in 'remote viewing', the…

Their critique therefore linked two mechanisms:

  1. Ambiguous descriptions that fit many possible targets.
  2. Extraneous cues that help judges resolve the ambiguity.

Neither mechanism alone necessarily explains every reported result, but together they offered a conventional explanation that critics believed had not been adequately excluded in the original studies.

How Scoring Rules Could Reduce Hindsight Matching

The debate helped encourage more rigorous judging procedures in later remote-viewing research, regardless of researchers’ views about the underlying phenomenon.

Common methodological improvements include:

  • removing all identifying information from transcripts before judging
  • randomising both transcript and target order
  • using independent judges with no knowledge of the experiment
  • defining scoring rules before evaluation begins
  • requiring judges to rank all candidate targets rather than selecting one after discussion
  • measuring agreement across multiple judges instead of relying on a single evaluator

Supporters of remote viewing have argued that later protocols adopted stronger blinding and scoring procedures than the early SRI experiments, while critics have continued to debate whether these changes fully eliminate subjective interpretation.[SciSpace+2Journal of Scientific Exploration]scispace.cominformation transmission in remote viewing experiments 4jd6pdendvIN a recent Jetter to Nature 1 Marks and.

Why the Flexible-Match Critique Remains Important

The issue of free-response descriptions remains significant because it concerns experimental design rather than belief about psychic phenomena. Even researchers who disagree about whether remote viewing exists generally recognise that open-ended reports require especially careful evaluation procedures.

Marks and Kammann’s criticism highlighted a general principle used throughout psychological research: whenever responses are vague enough to support multiple interpretations, scoring methods must minimise hindsight, expectancy and subjective judgement. Their argument therefore extended beyond the specific transcripts they examined, drawing attention to the broader challenge of distinguishing genuinely predictive descriptions from matches that appear convincing only after the target is known.[SciSpace]scispace.cominformation transmission in remote viewing experiments 4jd6pdendvIN a recent Jetter to Nature 1 Marks and.
