imagination-1｜untested

Claim: Imagination is a transformative mechanism that "gives beliefs fluidity," helping to convert beliefs into physical experience; one must learn to use imagination to move into and out of ideas. (personal-reality §619)

Evidence (verified via Crossref):

• Nexhmedin Morina, Jaap Lancee, Arnoud Arntz (2017). Imagery rescripting as a clinical intervention for aversive memories: A meta-analysis. Journal of Behavior Therapy and Experimental Psychiatry. https://doi.org/10.1016/j.jbtep.2016.11.003 —— 19 studies support imagery rescripting improving related psychological symptoms, but cannot prove that beliefs are transformed into external physical events via a special mechanism. Paper

Adjudication experiment: A pre-registered three-arm randomized trial with approximately 300 participants, comparing imagery rescripting, matched-duration verbal cognitive reappraisal, and an active control; intervention for 6 weeks with 3-month follow-up. Primary outcomes are belief-updating tasks, avoidance behavior, and independently assessed daily functioning; analyses will test whether expectancy, emotion, and behavior change mediate treatment effects. To test materialization beyond these pathways, external outcomes unaffected by participant behavior must be separately specified; this trial cannot adjudicate an undefined materialization mechanism.

Suggested paper title: Imagery Rescripting and Belief Updating: A Pre-registered Randomized Trial of Behavioral and Functional Outcomes

Core disruption: If external effects excluding behavior and known physiological pathways were confirmed, this would revise the working assumption that "the influence of beliefs on external events must be transmitted through identifiable physical causal pathways."

Related teams/funders: Nexhmedin Morina; Arnoud Arntz; Jaap Lancee

Specificity of Seth formulation: "Giving beliefs fluidity" can be mapped to cognitive flexibility and belief updating, but no unique variables, timescales, or effect directions are specified; the materialization component likewise offers no predictions that can be distinguished from existing models.

Remarks: The full entry is rated according to the core mechanism of the original claim; evidence for weaker versions is noted separately; "untested" indicates that no direct test was found in this search and does not prove that no one worldwide has studied it. All sample sizes are planned magnitudes and must be finalized with minimum meaningful effects, power simulations, and attrition rates; the proposed English titles are not published papers.

imagination-2｜contradicted

Claim: If you allow yourself to imagine misery, illness, or loneliness, these imaginings will be automatically materialized, because thoughts themselves bring about conditions that confer physical reality upon them. (early-sessions-8 §340)

Evidence (verified via Crossref):

• Tessa Rooney, Louise Sharpe, Jemma Todd, Biya Tang, Ben Colagiuri (2024). The nocebo effect across health outcomes: A systematic review and meta-analysis. Health Psychology. https://doi.org/10.1037/hea0001326 —— Negative expectancies can increase or worsen certain symptoms, but this is a condition-dependent nocebo effect, not the automatic occurrence of illness or tragic events. Paper

Adjudication experiment: Approximately 360 healthy adults randomized to brief negative health imagery, neutral imagery, or negative verbal expectancy; using safe, matched-intensity sensory stimulation, with blinded ratings of pain report, skin conductance, heart rate, and behavior; single session plus 7-day follow-up. Pre-registered comparison of "necessity" versus probabilistic expectancy models; subjective symptom change cannot serve as evidence of organic disease occurrence, nor should the experiment induce real illness.

Suggested paper title: Negative Mental Imagery and Symptom Expectancy: A Pre-registered Randomized Test of Subjective and Physiological Outcomes

Core disruption: If illness were necessarily generated by imagination, this would overturn the clinical causal assumption that "negative expectancy is not a sufficient condition for organic disease occurrence."

Related teams/funders: Ben Colagiuri; Louise Sharpe; Jemma Todd

Specificity of Seth formulation: "Automatically materialized" is stronger than the nocebo model, implying a sufficient condition or near-necessity; but the original text gives no onset timeframe or event-matching criteria, leaving it open to post hoc interpretation.

Remarks: "contradicted" applies to the strong assertion that "negative imagination is sufficient to automatically produce corresponding reality"; illness or loneliness cannot be attributed to a patient's imagination on this basis, nor can symptom reports be equated with tissue damage.

imagination-3｜contested

Claim: Changing one's imagination and expectation of another person continuously sends telepathic suggestions to them, influencing their behavior. (early-sessions-8 §340)

Evidence (verified via Crossref):

• Abby L. Pooley, Aja L. Murray, Caroline Watt (2023). Understanding the Factors at Play in the Sender-Receiver Dynamic During the Telepathy Ganzfeld: A Meta-Analysis. Journal of Anomalous Experience and Cognition. https://doi.org/10.31156/jaex.23878 —— Summarizes Ganzfeld sender–receiver studies as relevant anomalous-information-transfer literature, but does not validate that changing expectancy continuously and remotely alters another's behavior. Paper

Adjudication experiment: Multicenter pre-registered study with approximately 800 pairs; senders randomly imagine receivers making a specified neutral choice or enter a no-sending condition; receivers, on-site experimenters, and analysts are blinded to group assignment. Both parties are isolated with communication prohibited; targets assigned by an independent server. Primary outcome is the match rate between receivers' actual choices and specified targets. Each pair completes multiple sessions over 4 weeks; total project duration approximately 12–18 months. Analysis is at the pair level, with all trials made public and independent replication by a separate team.

Suggested paper title: Remote Expectancy and Recipient Choice Under Sensory Isolation: A Multicenter Pre-registered Randomized Study

Core disruption: If recipient behavior could be reproducibly altered while all known communication channels are blocked, this would revise the assumption that "interpersonal expectancy effects depend on transmissible sensory, behavioral, or technological signals."

Related teams/funders: Caroline Watt; Aja L. Murray; Abby L. Pooley; University of Edinburgh, Koestler Parapsychology Unit

Specificity of Seth formulation: The discriminable prediction is that after the sender changes their imagination, the behavior of the non-contacted receiver changes in a targeted direction; the original text specifies no effect size, distance decay, or duration.

Remarks: "contested" indicates that the adjacent anomalous-information-transfer literature contains reporting and methodological disputes, not that this sustained behavioral-suggestion mechanism has received direct support; ordinary self-fulfilling prophecy cannot serve as telepathy evidence.

imagination-4｜untested

Claim: Imagination is not bound by time; it can imagine the past and the future, helping to bring implicit universal elements into actual experience, and combined with reasoning, yields knowledge. (dreams-evolution-2 §916)

Evidence (verified via Crossref):

• Daniel L. Schacter, Roland G. Benoit, Karl K. Szpunar (2017). Episodic Future Thinking: Mechanisms and Functions. Current Opinion in Behavioral Sciences. https://doi.org/10.1016/j.cobeha.2017.06.002 —— Episodic future thinking uses memory and constructive processes to simulate the future and participates in planning and decision-making; does not demonstrate access to universal information independent of memory and inference. Paper

Adjudication experiment: Approximately 300 participants complete a pre-registered temporal representation experiment comparing recall of the past, simulation of the future, and evidence-based inference; a separate independent verification module requires submission of unmodifiable predictions before random target generation, with targets subsequently produced by an isolated server. Approximately 100 trials per person over 4 weeks; scoring and stopping rules fixed in advance, analyzed with participant-level hierarchical models. The two modules separately adjudicate ordinary temporal simulation ability and accuracy beyond known information; they cannot be merged into a single outcome.

Suggested paper title: Temporal Simulation and Information Accuracy: A Pre-registered Comparison of Memory, Prospection, and Prediction

Core disruption: If information not yet generated and not inferable could be accurately obtained, this would revise the assumption that "future episodic construction depends on existing information and does not access future random events."

Related teams/funders: Daniel L. Schacter; Roland G. Benoit; Karl K. Szpunar

Specificity of Seth formulation: Imagining the past and future is a supported ordinary cognitive ability; "not bound by time" and "implicit universal elements" are undefined, gaining additional discriminability only if unknown-information acquisition is explicitly predicted.

Remarks: Treating the past or future as thought content does not imply the cognitive process itself transcends physical time; the original text also does not explicitly promise precognition of random targets, so that module is a strengthened operationalization requiring prior agreement.

imagination-5｜untested

Claim: Imagination allows entry into other realities or levels, for example experiencing a cat's sense of time through imagination. (unknown-reality-1 §680)

Evidence (verified via Crossref):

• F. Macar, N. Vitton (1979). Contingent negative variation and accuracy of time estimation: a study on cats. Electroencephalography and Clinical Neurophysiology. https://doi.org/10.1016/0013-4694(79)90222-0 —— Cats' time estimation has measurable behavioral and EEG indices that can provide objective prediction targets; the paper does not study humans entering feline experience through imagination. Paper

Adjudication experiment: First establish a held-out dataset using approximately 30–50 cats in non-invasive, reward-based temporal discrimination tasks; approximately 240 adults are randomly assigned to "imagine being a cat," animal behavior knowledge learning, or neutral imagination, and predict temporal discrimination thresholds and error patterns in the unseen cat data. Cat task training and data collection take approximately 3–6 months; the adult component takes 4 weeks. Prediction calibration is compared with control for cat-ownership experience; even successful prediction would only support informational or model accuracy, not directly validate shared subjective experience.

Suggested paper title: Cross-Species Temporal Perspective Taking: Predicting Feline Interval Discrimination Through Guided Imagery

Core disruption: Only proof of acquiring species-specific information that excludes learning, inference, and information leakage would revise the assumption that "cross-species perspective-taking depends on human internal models."

Related teams/funders: Joel Pearson; University of New South Wales, Future Minds Lab

Specificity of Seth formulation: "Experiencing a cat's sense of time" is a concrete example, but does not specify how feline time sense differs, nor provide independently checkable criteria for subjective experience.

Remarks: Cats' behavioral thresholds are not equivalent to feline phenomenal consciousness; the listed team studies human imagination and is a methodological collaboration candidate, not evidence that they are researching entry into other realities. Team

imagination-6｜contested

Claim: In the dream state, imagination and creative aspects are given greater latitude; problem solving follows intuitive role-playing rather than reasoning processes. (esp-power §14)

Evidence (verified via Crossref):

• Adam Haar Horowitz, Kathleen Esfahany, Tomás Vega Gálvez, Robert Stickgold, Pattie Maes (2023). Targeted dream incubation at sleep onset increases post-sleep creative performance. Scientific Reports. https://doi.org/10.1038/s41598-023-31361-w —— Targeted dream incubation at sleep onset enhances creative performance related to the incubated theme, but does not prove role-playing or the complete absence of reasoning. Paper
• Célia Lacaux, Thomas Andrillon, Céleste Bastoul, Yannis Idir, Alexandrine Fonteix-Galet, Isabelle Arnulf, Delphine Oudiette (2021). Sleep onset is a creative sweet spot. Science Advances. https://doi.org/10.1126/sciadv.abj5866 —— A 103-person study found that brief N1 sleep is associated with subsequent discovery of hidden mathematical rules, with effects constrained by sleep stage and task conditions. Paper

Adjudication experiment: Approximately 240 participants randomly assigned to four groups: N1 role-perspective incubation, N1 non-role thematic incubation, waking role imagination, or waking analytical condition; all first learn identical problems, then undergo polysomnography and timed reports; the next day tests include transfer to new problems and blinded creativity assessment. Three sessions per person approximately 1 week apart, 6 months total; pre-registered coding standards for perspective shifts and explicit reasoning in dream reports, with control for actual sleep stage.

Suggested paper title: Role-Based Dream Incubation and Creative Problem Solving: A Pre-registered Sleep-Laboratory Trial

Core disruption: If role-playing has an independent causal effect after matching sleep-stage and thematic cues, this would revise the interpretation that "sleep's problem-solving benefits arise solely from memory reorganization and are independent of dream role content," though this interpretation is not field consensus.

Related teams/funders: Adam Haar Horowitz; Pattie Maes; Delphine Oudiette; Thomas Andrillon

Specificity of Seth formulation: Dreams facilitating certain creative processes overlaps with existing hypotheses; "intuitive role-playing rather than reasoning" is more specific but currently lacks direct mechanistic comparison.

Remarks: "contested" applies to the compound mechanism and scope of generalization; existing positive results cannot be generalized to all dreams enhancing creativity, nor can in-sleep reasoning be fully excluded from waking reports.

imagination-7｜untested

Claim: The operation of imagination involves mental enzymes that produce chemical effects at the physical level and can be observed through chemical effects. (early-sessions-1 §19)

Evidence (verified via Crossref):

• Marc J. Weigensberg, Cheng K. Fred Wen, Donna Spruijt-Metz, Christianne Joy Lane (2022). Effects of Group-delivered Stress-reduction Guided Imagery on Salivary Cortisol, Salivary Amylase, and Stress Mood in Urban, Predominantly Latino Adolescents. Global Advances in Health and Medicine. https://doi.org/10.1177/21649561211067443 —— A 111-adolescent study measured salivary amylase but found no significant within- or between-group changes; cortisol and mood outcomes cannot prove the existence of special enzymes. Paper
• Frances A. Maratos, David Sheffield (2020). Brief Compassion-Focused Imagery Dampens Physiological Pain Responses. Mindfulness. https://doi.org/10.1007/s12671-020-01485-5 —— A compassion-imagery study measured salivary alpha-amylase responses under pain conditions, demonstrating precedent for this measurement paradigm, but did not identify unique imagination enzymes. Paper

Adjudication experiment: Feasible design: approximately 120 participants in a randomized crossover completing vivid neutral imagery, emotional imagery, difficulty-matched verbal rumination, and rest, with sessions separated by at least 48 hours over 2–3 weeks total. Saliva samples are collected at baseline, immediately post-task, and at 10 and 30 minutes; pre-registered primary outcomes are alpha-amylase activity and secretion rate, with concurrent recording of saliva flow, heart rate variability, skin conductance, and respiration, controlling for sampling time, diet, medication, and oral condition. For peripheral blood enzymology, a separate exploratory cohort of approximately 60 is screened for candidate enzymes, then validated in an independent cohort of approximately 200; total project duration 9–12 months. After detecting relevant changes, molecular identity, substrates, and catalytic function must still be established before proposing a novel enzyme mechanism.

Suggested paper title: Salivary Alpha-Amylase Activity During Vivid Mental Imagery: A Pre-registered Randomized Crossover Study

Core disruption: Only identification of a novel catalytic mechanism independent of known autonomic and metabolic pathways, with causal action specific to imagination, would revise the assumption that "imagination-related chemical changes are explained by known physiological pathways."

Related teams/funders: Marc J. Weigensberg; Frances A. Maratos; David Sheffield

Specificity of Seth formulation: Mental enzymes have no molecular identity, tissue origin, substrates, reaction direction, or timescale; "having chemical effects" is no more specific than modern physiology.

Remarks: Answering question 1: measurable and with existing related experiments, but resting controls are insufficient to exclude general arousal effects; cortisol is a hormone rather than an enzyme, and peripheral enzyme activity cannot directly represent brain enzyme activity.

imagination-8｜untested

Claim: Physical tools can induce imagination to move along personal memories, but cannot force it to engage in conceptual thinking. (early-sessions-1 §19)

Evidence (verified via Crossref):

• Jonathan Curot and colleagues (2017). Memory scrutinized through electrical brain stimulation: A review of 80 years of experiential phenomena. Neuroscience & Biobehavioral Reviews. https://doi.org/10.1016/j.neubiorev.2017.04.018 —— Brain electrical stimulation sometimes evokes recall-like experiences, but content is complex and does not equal precise movement along a memory timeline. Paper
• Preston P. Thakral, Kevin P. Madore, Sarah E. Kalinowski, Daniel L. Schacter (2020). Modulation of hippocampal brain networks produces changes in episodic simulation and divergent thinking. Proceedings of the National Academy of Sciences. https://doi.org/10.1073/pnas.2003535117 —— Network-targeted TMS can modulate episodic simulation and divergent thinking, weakening the interpretation that "physical intervention only affects memory," but does not prove the ability to force specified concepts. Paper

Adjudication experiment: Multicenter recruitment of approximately 40–60 patients with intracranial electrodes already implanted for clinical needs; randomized interleaved stimulation versus sham stimulation, comparing autobiographical recall, concept combination, and no-task rest; blinded ratings of recall detail, semantic combination, and spontaneous novel concepts. Two to four short sessions per person, project duration 18–24 months. A distinction is drawn in advance between "altering the probability of concept generation" and "reliably eliciting concepts without relevant task instructions"; the former is easily testable, while the latter more closely approximates forced production.

Suggested paper title: Differential Effects of Brain Stimulation on Autobiographical Recall and Novel Concept Generation

Core disruption: Validation of this claim would not itself overturn mainstream views, because mainstream does not assume brain stimulation can force arbitrary concepts; proving a strict dissociation between memory and concept generation would only revise specific models of shared functional networks.

Related teams/funders: Jonathan Curot; Emmanuel J. Barbeau; Preston P. Thakral; Daniel L. Schacter

Specificity of Seth formulation: The memory–concept contrast is operationalizable, but "force" has no success rate or task conditions; the negation of all future physical tools cannot be confirmed by finite negative experiments.

Remarks: Rated "untested" with respect to the original's absolute capability boundary; modulation, suppression, elicitation, and precise control are four distinct claims and cannot substitute for one another.

imagination-9｜untested

Claim: After training imagination through practice (such as imagining oneself in another time and place before sleep), you will be better able to handle present events and receive increasingly valuable information. (nature-of-psyche §793)

Evidence (verified via Crossref):

• Adam Haar Horowitz, Kathleen Esfahany, Tomás Vega Gálvez, Robert Stickgold, Pattie Maes (2023). Targeted dream incubation at sleep onset increases post-sleep creative performance. Scientific Reports. https://doi.org/10.1038/s41598-023-31361-w —— Provides adjacent evidence that pre-sleep thematic cues improve some creative performance, but does not test weeks of "another time and place" practice for transfer to real-world functioning. Paper

Adjudication experiment: A feasible three-arm randomized trial with approximately 360 participants: pre-sleep episodic imagery of another time and place, matched-duration review of the day's events, and expectancy-matched relaxation training; 10–15 minutes nightly for 6 weeks with 3-month follow-up. Pre-registered composite score on unfamiliar problem-solving tasks as the primary outcome, VVIQ imagery vividness as a secondary outcome; daily diaries and blinded ratings check real-world problem handling. Sleep, adherence, and intervention expectancy are recorded; growth trajectories are tested at weeks 0, 3, and 6. "Valuable information" must be scored separately for accuracy and practical utility.

Suggested paper title: Bedtime Scene Simulation and Transfer to Everyday Problem Solving: A Six-Week Pre-registered Randomized Trial

Core disruption: If stable cross-task and real-world transfer emerged, this would revise the conservative assumption that "short-term imagery training benefits are largely confined to trained content and lack far transfer."

Related teams/funders: Adam Haar Horowitz; Pattie Maes; Daniel L. Schacter

Specificity of Seth formulation: Provides directional predictions of bedtime practice and ability improvement over time, but does not specify whether another time and place must exceed ordinary episodic simulation, nor define information value.

Remarks: Answering question 3: randomized controlled trials are feasible; an isolated increase in VVIQ scores may reflect expectancy or questionnaire response shifts and must be paired with objective performance and untrained tasks.

imagination-10｜untested

Claim: Imagination and reason are complementary: imagination handles the implicit universe, reason handles immediate evidence; every act of imagination contains reasoning, and every act of reasoning contains imagination. (dreams-evolution-2 §917)

Evidence (verified via Crossref):

• Jérôme Prado, Angad Chadha, James R. Booth (2011). The Brain Network for Deductive Reasoning: A Quantitative Meta-analysis of 28 Neuroimaging Studies. Journal of Cognitive Neuroscience. https://doi.org/10.1162/jocn_a_00063 —— Different argument forms depend on varying degrees of verbal, spatial, and control systems, not supporting inference from a single network that all reasoning necessarily contains the same kind of imagination. Paper
• Daniel L. Schacter, Roland G. Benoit, Karl K. Szpunar (2017). Episodic Future Thinking: Mechanisms and Functions. Current Opinion in Behavioral Sciences. https://doi.org/10.1016/j.cobeha.2017.06.002 —— Supports functional links between future simulation, planning, and decision-making, but does not establish a universal proposition of mutual containment between imagination and reasoning. Paper

Adjudication experiment: Question 2: approximately 150 participants, including approximately 50 with multi-index-confirmed aphantasia, complete formal logic, imagery-assisted logic, standalone episodic imagery, and working-memory control conditions; difficulty, reaction time, and verbal load are matched; two fMRI sessions per person, with independent localization of default-mode, executive-control, and sensory-imagery networks, combined with multivariate decoding and behavioral interference tests. Question 5: an additional approximately 300 participants are randomized to imagining possible outcomes before evaluation, direct rational evaluation, or matched-duration verbal enumeration, using decision tasks with clear correct answers or payoff distributions; accuracy, calibration, payoff, and heart rate variability (with respiration controlled) are measured; 4-week repeated testing, total project duration 9–12 months.

Suggested paper title: Imagery–Reasoning Interactions in Deduction and Decision Accuracy: Pre-registered Behavioral, fMRI, and Autonomic Tests

Core disruption: If strict proof emerged that any reasoning necessarily recruits an independently defined imagery mechanism, this would overturn the assumption that "at least some propositional reasoning can be completed without sensory imagery participation."

Related teams/funders: Jérôme Prado; Daniel L. Schacter; Roger E. Beaty; Pennsylvania State University, Cognitive Neuroscience of Creativity Laboratory

Specificity of Seth formulation: "Any" is a stronger prediction than a general complementary relationship; but if all internal representations are defined as imagination, the proposition becomes definitionally circular, and "implicit universe" currently has no measurable counterpart.

Remarks: Answering questions 2 and 5: both experiment types are feasible, but DMN activation alone cannot prove imagination, nor does its absence prove non-existence; heart rate variability is not an indicator of knowledge accuracy, and finite tasks cannot prove universal propositions.

imagination-11｜contradicted

Claim: Imagination belongs to the mind rather than the brain; no physical tool can force imagination to produce original concepts or ideas. (early-sessions-1 §19)

Evidence (verified via Crossref):

• Joel Pearson (2019). The human imagination: the cognitive neuroscience of visual mental imagery. Nature Reviews Neuroscience. https://doi.org/10.1038/s41583-019-0202-9 —— Integrates evidence on neural representation, individual differences, and intervention for imagery, supporting visual imagination as having a researchable neural implementation.

Proceedings of the National Academy of Sciences. https://doi.org/10.1073/pnas.2003535117 —— fMRI-guided TMS produces selective effects on episodic simulation and divergent thinking, providing causal evidence of brain-network involvement. Paper
• Eleonora Bartoli and colleagues (2024). Default mode network electrophysiological dynamics and causal role in creative thinking. Brain. https://doi.org/10.1093/brain/awae199 —— Intracranial recordings from 13 patients, with stimulation experiments in 9, found that perturbing the default-mode network reduces response originality rather than merely reducing response count. Paper

Adjudication experiment: Answering question 4: approximately 120 participants undergo a randomized, blinded, crossover TMS experiment targeting individually localized left angular gyrus or hippocampal-connected cortical nodes, comparing continuous theta-burst stimulation, intermittent theta-burst stimulation, and matched sham stimulation; three sessions at least 1 week apart. Alternate uses and novel concept combination tasks are administered; primary outcome is blinded novelty ratings, secondary outcome is the number of valid responses reaching a pre-specified novelty threshold, with control for total fluency, language, and attention. TMS-EEG or fMRI verifies actual network effects, 6–9 months total; one cannot presuppose that the two stimulation types necessarily inhibit or excite in all individuals and higher-order cortices.

Suggested paper title: Causal Modulation of Original Idea Generation by Network-Targeted Transcranial Magnetic Stimulation

Core disruption: If original concept generation were shown to be entirely independent of brain function, this would overturn the neuroscience assumption that "creative thinking depends on causal contributions of brain networks."

Related teams/funders: Preston P. Thakral; Daniel L. Schacter; Eleonora Bartoli; Ben Shofty; Joel Pearson

Specificity of Seth formulation: If "belonging to the mind rather than the brain" means independence from brain activity, it conflicts with causal intervention evidence; if the brain is still allowed as a necessary interface, TMS results alone cannot adjudicate this ontological interpretation.

Remarks: "contradicted" is limited to the empirical interpretation of brain independence; "no instrument can force a designated original concept to appear" is still not directly falsified, and reducing or increasing originality is not equivalent to forcing generation of specific thoughts.

imagination-12｜contradicted

Claim: Without first imagining oneself as one is, the individual cannot physically survive. (unknown-reality-2 §732)

Evidence (verified via Crossref):

• Adam Zeman, Michaela Dewar, Sergio Della Sala (2015). Lives without imagery – Congenital aphantasia. Cortex. https://doi.org/10.1016/j.cortex.2015.05.019 —— Reports surviving adults with congenital absence of voluntary visual imagery, providing counterexamples to the interpretation that "explicit imagery must precede survival." Paper
• Alexei J. Dawes, Rebecca Keogh, Thomas Andrillon, Joel Pearson (2020). A cognitive profile of multi-sensory imagery, memory and dreaming in aphantasia. Scientific Reports. https://doi.org/10.1038/s41598-020-65705-7 —— A larger sample shows that some individuals with aphantasia report widespread multi-sensory imagery deficits, but this cannot establish that all their implicit self-representations are absent. Paper

Adjudication experiment: Establish a cohort of approximately 300 adults with multi-sensory aphantasia confirmed by questionnaire and objective imagery indices, alongside 300 matched controls; assess self-imagery, body ownership, interoception, daily living capacity, and health records, with 12-month follow-up. Existing data from severe disorders of consciousness and anesthesia are additionally analyzed for life-maintenance and consciousness indicators. No life-threatening manipulation is needed: if the proposition refers to explicit self-imagery, reliably confirming individuals without such imagery who nevertheless survive already suffices to refute the necessary condition; if it refers to implicit physiological self-models, the target of the test must be redefined.

Suggested paper title: Is Explicit Self-Imagery Necessary for Everyday Functioning? A Prospective Study of Multisensory Aphantasia

Core disruption: If explicit self-imagery were indeed necessary for survival, this would overturn the physiological assumption that "basic life maintenance can persist in the absence of explicit self-representation."

Related teams/funders: Adam Zeman; Rebecca Keogh; Joel Pearson; Alexei J. Dawes

Specificity of Seth formulation: Read as explicit imagery, it proposes a strong necessary condition for survival, for which counterexamples already exist; if imagination is expanded to any cellular regulation or implicit model, it loses discriminability from existing homeostatic theory.

Remarks: Aphantasia does not entail absence of thought, all imaginative capacity, or self-awareness; the rating therefore targets the literal interpretation of explicit self-imagery, and visual aphantasia alone cannot negate all broad mental representations.
