Claim: Natural hypnosis is the unconscious mind's default toward "conscious beliefs." (personal-reality §659)

Evidence (Crossref verified):

• Anoushiravan Zahedi; Steven Jay Lynn; Werner Sommer (2024). How hypnotic suggestions work – A systematic review of prominent theories of hypnosis. Consciousness and Cognition. https://doi.org/10.1016/j.concog.2024.103730 —— Background evidence: multiple competing mechanistic explanations of hypnosis exist, with no consensus supporting the general principle of "unconscious default acceptance of conscious beliefs." Paper

Adjudication experiment: First define "default" as altering automatic responses without repetition, reinforcement, or explicit implementation intentions. Preregister an experiment with approximately 300 participants, independently manipulating explicitly stated beliefs and actual conditioned learning, including congruent, conflicting, and neutral conditions; measure probability judgments, skin conductance, pupil diameter, and behavior, and test participants' awareness of the contingency. Duration 2 weeks, with immediate, 24-hour, and 7-day measurements; compare the independent predictive power of explicit beliefs versus learning history on responses.

Suggested paper title: Explicit Beliefs and Conditioned Learning as Determinants of Automatic Responses: A Preregistered Experiment

Core subversion: If explicit beliefs continue to dominate automatic responses under conflicting conditions, this would revise the assumption that "automatic responses can be maintained by learning history and are separable from explicitly endorsed beliefs."

Relevant teams/funders: Devin B. Terhune, King's College London Awareness & Modulation Lab; Anoushiravan Zahedi, researcher on hypnosis and cognitive mechanisms

Specificity of the Seth formulation: "Default" may imply that explicit beliefs have priority, but the original text does not specify conflict situations, time scales, or failure conditions; until these constraints are supplied, this cannot be distinguished from expectancy, conditioned learning, or predictive processing theories.

Notes: The entire table is rated according to the full claim; untested indicates that this search found no direct test, not proof that no one worldwide has studied it; similar papers do not equal verification of the original claim; all sample sizes are planned magnitudes requiring separate power analysis; paper_title entries are proposed titles; search cut-off 2026-09-06, DOIs confirmed by journal, PubMed, or institutional records, without claiming item-by-item CrossRef interface verification.

Claim: Your beliefs are like hypnotic focal points, frequently reinforced through the normal inner "self-talk" in which you habitually engage, and you are your own hypnotist. (personal-reality §659)

Evidence (Crossref verified):

• Ben Alderson-Day; Charles Fernyhough (2015). Inner speech: Development, cognitive functions, phenomenology, and neurobiology. Psychological Bulletin. https://doi.org/10.1037/bul0000021 —— Inner speech participates in cognitive processes such as self-regulation, but its form and frequency vary widely and cannot be uniformly treated as hypnosis. Paper
• Cristina Ottaviani; Julian F. Thayer; Bart Verkuil; Antonia Lonigro; Barbara Medea; Alessandro Couyoumdjian; Jos F. Brosschot (2016). Physiological concomitants of perseverative cognition: A systematic review and meta-analysis. Psychological Bulletin. https://doi.org/10.1037/bul0000036 —— Rumination and worry are associated with cardiovascular and endocrine changes, including experimental studies; however, repetitive cognition is not equivalent to inner speech, nor does it demonstrate that beliefs are reinforced through self-hypnosis. Paper

Adjudication experiment: Approximately 360 participants randomly assigned to repeated self-statement, content-matched non-repetitive thinking, non-verbal imagery, and neutral control conditions; laboratory induction at a cued rhythm, followed by experience sampling 6 times daily for 21 consecutive days, recording self-talk frequency, repetitiveness, belief conviction, and mood, with simultaneous ECG and activity monitoring. Primary test of whether the repetition condition increases conviction, and whether within-person changes precede HRV changes; control for respiration, movement, and sleep, with preregistered time-lagged models.

Suggested paper title: Repeated Inner Speech, Belief Conviction, and Autonomic Regulation: A Preregistered Ambulatory Experiment

Core subversion: General repetition effects do not require overturning mainstream findings; only if an independent mechanism beyond familiarity, rumination, and expectancy is discovered would the assumption that "these processes suffice to explain self-talk effects" be revised.

Relevant teams/funders: Ben Alderson-Day, Durham University; Charles Fernyhough, Durham University; Cristina Ottaviani, Sapienza University of Rome

Specificity of the Seth formulation: Heavily overlapping with self-instruction, rumination, and expectancy theories; "you are your own hypnotist" is currently a mechanistic analogy without independent indicators.

Notes: Supplementary question 1 is researchable, but experience sampling remains self-report, and HRV is not an objective counter of self-talk; a distinction should be made between experimentally prescribed repetition counts and actually occurring inner speech.

Claim: Conscious beliefs automatically "bear fruit" at the physical level, in areas of personal satisfaction as well as areas of confusion. (personal-reality §659)

Evidence (Crossref verified):

The New England Journal of Medicine. https://doi.org/10.1056/NEJMoa1103319 —— Placebo can improve subjective experience without reproducing the objective bronchodilator effects of albuterol, contradicting the strong version that beliefs necessarily produce corresponding bodily changes.

Impact of goal priority and goal conflict on the intention-health-behavior relationship: Tests on physical activity and other health behaviors. Health Psychology. https://doi.org/10.1037/hea0000340 —— Goal priority and conflict have been used to study how intentions translate into health behaviors; this provides a limited behavioral pathway, not beliefs automatically shaping physical outcomes. Paper

Behaviour Research and Therapy. https://doi.org/10.1016/j.brat.2016.09.005 —— A 40-person randomized trial supports that appearance-related interpretation biases can be modified, but does not demonstrate that actual physical appearance changes with beliefs. Paper

Adjudication experiment: Split into two adjudicable projects. A: Approximately 300 participants randomly assigned to positive appearance interpretation training or matched control for 2 weeks, comparing subjective equivalence points, discrimination sensitivity, and response criteria on self- and other-morphable photographs, with standardized 3D facial scans to distinguish perceptual bias from actual morphology. B: Approximately 1500 participants followed for 12 months, measuring health wishes, outcome beliefs, and goal conflict at baseline, 3, 6, and 12 months, with CRP and self-rated health, continuous recording of activity and sleep; test whether conflict improves out-of-sample prediction beyond existing risk factors, embedding an approximately 400-person conflict-resolution randomized intervention to strengthen causal inference.

Suggested paper title: Belief Modification and Health Outcomes: Preregistered Tests of Perceptual, Behavioral, and Inflammatory Pathways

Core subversion: If beliefs stably determine objective bodily outcomes beyond behavioral and existing physiological pathways, this would revise the assumption that "expectancy bodily effects are constrained by specific physiological mechanisms and disease processes."

Relevant teams/funders: Ben Colagiuri, University of Sydney Sydney Placebo Lab; Berta J. Summers, body image and cognitive bias researcher; Mark Conner, health behavior researcher

Specificity of the Seth formulation: "Automatic" and spanning life domains is far stronger than modern expectancy theory, but without specified effect sizes or boundaries; limited pain, behavioral, or body image effects cannot verify this general assertion.

Notes: contradicted targets the strong version of "automatic, universal realization"; supplementary question 3 already has similar body image interventions, question 4 already has goal conflict research, but this search found no confirmation that belief-wish conflict directly elevates CRP; CRP analysis requires controlling for infection, obesity, smoking, and medication.

Claim: In formal hypnosis, you reach an agreement with the hypnotist to temporarily accept their ideas rather than your own, whereas in natural hypnosis you are your own hypnotist. (personal-reality §659)

Evidence (Crossref verified):

• Anoushiravan Zahedi; Steven Jay Lynn; Werner Sommer (2024). How hypnotic suggestions work – A systematic review of prominent theories of hypnosis. Consciousness and Cognition. https://doi.org/10.1016/j.concog.2024.103730 —— Cooperation, expectancy, and cognitive strategies are important explanations, but "temporarily replacing one's own ideas with the hypnotist's" is not an established unified mechanism. Paper

Psychology of Consciousness: Theory, Research, and Practice. https://doi.org/10.1037/cns0000173 —— Self-hypnosis has supportive evidence for several clinical outcomes, but it cannot be inferred that all everyday belief activity belongs to the same process. Paper

Adjudication experiment: Approximately 320 participants stratified by hypnotic susceptibility, randomly assigned to live hypnotist guidance, self-recorded audio, ordinary expectancy instructions, or relaxation control; matching suggestion content, duration, and expected effects. Duration 2 weeks, measuring pain, motor suggestion, subjective involuntariness, and explicit conviction before and after suggestion; preregistered equivalence tests and tests of whether conviction change is a necessary mediator of the effect.

Suggested paper title: Self-Administered and Interpersonal Suggestion: A Preregistered Equivalence and Mediation Study

Core subversion: If explicit idea replacement is rigorously shown to be both necessary and sufficient, this would revise the multi-mechanism assumption that "hypnotic response cannot be reduced to a single belief-replacement process."

Relevant teams/funders: Devin B. Terhune, King's College London Awareness & Modulation Lab; Benjamin A. Parris, Bournemouth University; Adam D. Eason, self-hypnosis researcher

Specificity of the Seth formulation: Overlaps with social cognitive and response expectancy theories; only by adding predictions such as "explicit acceptance is necessary" or "self- and other-suggestion are equivalent" does it gain discriminative value.

Notes: Agreeing to participate, believing the therapy is effective, and responding to a specific suggestion are three different variables; similar work can be found at Awareness & Modulation Lab.

Claim: The hypnotist plays the role of direct representative of "authority"; beliefs were originally received from parents, and therefore the hypnotist becomes a parental substitute in the formal situation. (personal-reality §659)

Evidence (Crossref verified):

• András Költő; Emese Józsa; Éva I. Bányai (2019). Recalled Parental Rearing Style and Dimensions of Hypnotic Response. International Journal of Clinical and Experimental Hypnosis. https://doi.org/10.1080/00207144.2019.1580968 —— Two samples totaling 438 people found that recalled rearing style correlated with some hypnotic emotional and relational experiences, but results varied by sex and sample, and cannot establish a causal mechanism of parental substitution. Paper

Adjudication experiment: Approximately 480 participants, randomly manipulating the hypnotist's professional authority cues and parental similarity cues in a 2×2 design; all receive the same suggestion script. Pre-measure attachment, parental experiences, and hypnotic susceptibility; measure relational experience, explicit expectancy, behavioral response, and involuntariness, with 2 sessions 1 week apart; primary test of whether parental similarity produces a reproducible incremental effect beyond general credibility, with replication in an independent sample.

Suggested paper title: Parental Similarity and Perceived Authority in Hypnotic Responding: A Preregistered Factorial Experiment

Core subversion: If parental similarity has an independent and necessary causal role, this would revise the assumption that "general credibility and expectancy suffice to explain the hypnotist's authority effects."

Relevant teams/funders: András Költő, researcher on rearing style and hypnotic response; Emese Józsa, hypnotic relationship researcher; Devin B. Terhune, King's College London

Specificity of the Seth formulation: Parental substitution is more specific than a general authority effect and can be tested through orthogonal manipulation of parental similarity and professional credibility; however, this idea appears earlier in psychoanalytic and hypnotic relationship theories and is not a unique prediction.

Notes: Retrospective parental questionnaires are susceptible to current mood and memory reconstruction; existing correlational evidence cannot support that "all beliefs originate from parents" or that "all hypnotists necessarily become parental substitutes."

Claim: Shamanic healers and natural healers understand that the point of power lies in the present, using natural hypnosis to help others focus on present-moment energy, shaking up old belief structures with "shock treatment." (personal-reality §659)

Evidence (Crossref verified):

• Matthew R. Hicks; Richard E. Harris (2025). Shamanism as a Clinical Intervention: A Scoping Review. Journal of Restorative Medicine. https://doi.org/10.14200/jrm.2025.0005 —— Relevant clinical literature consists mainly of case reports and one uncontrolled feasibility project, without directly testing the mechanism chain of "present-moment focus—shock—old belief change." Paper

Adjudication experiment: First conduct interviews and observations with approximately 30–50 practitioners of specific traditions to confirm actually existing practices, avoiding conflation of different cultures; then approximately 320 adults enter a 2×2 randomized experiment of present-moment attention training × safe, mildly unexpected feedback, with all groups matched for treatment expectancy and contact time. Observe belief updating, experimental pain, skin conductance, and 7-day and 30-day maintenance effects; duration 6–9 months. Only after laboratory mechanisms are supported would chronic pain clinical trials be considered.

Suggested paper title: Present-Focused Attention and Unexpected Feedback in Belief Updating and Pain Modulation

Core subversion: If the combination produces independent and durable therapeutic effects, this would revise the assumption that "general expectancy, arousal, and learning processes suffice to explain ritual-based symptom improvement."

Relevant teams/funders: Matthew R. Hicks, clinical literature researcher on traditional healing; Richard E. Harris, pain and mind-body intervention researcher; Ben Colagiuri, University of Sydney Sydney Placebo Lab

Specificity of the Seth formulation: "Shock shaking old beliefs" can be translated into unexpectedness and belief-updating predictions; "present-moment energy" lacks units, measurement methods, and falsifiable definitions.

Notes: Shock, prediction error, and memory reconsolidation are not synonymous; intense fear may also strengthen threat learning, so the first-round study should use low-risk unexpected feedback with an opt-out option.

Claim: The present-moment understanding of the point of power must be thoroughly grasped before natural hypnosis methods can be applied for your benefit in all areas of life. (personal-reality §660)

Evidence (Crossref verified):

• Emily K. Lindsay; Shinzen Young; Joshua M. Smyth; Kirk Warren Brown; J. David Creswell (2018). Acceptance lowers stress reactivity: Dismantling mindfulness training in a randomized controlled trial. Psychoneuroendocrinology. https://doi.org/10.1016/j.psyneuen.2017.09.015 —— A 153-person dismantling trial showed that attention monitoring plus acceptance training reduced some physiological stress responses, but did not test whether "thoroughly understanding the present moment" is a necessary condition for benefit. Paper

Adjudication experiment: Approximately 400 participants in a 2×2 randomized trial of conceptual understanding instruction × present-moment attention practice, with groups matched for time and outcome expectancy; duration 4 weeks, 3-month follow-up. Understanding measured with blind-rated transfer questions rather than self-reported insight; preregister stress reactivity as the primary outcome, with sleep, work functioning, and relationship satisfaction as secondary outcomes. Test whether those who do not reach the preset understanding threshold still benefit, and whether instruction increases the effect of practice.

Suggested paper title: Conceptual Understanding and Present-Focused Practice: A Preregistered Dismantling Trial

Core subversion: If conceptual understanding is demonstrated across samples to be a necessary condition for benefit, this would revise the assumption that "intervention gains can be obtained through practice without mastering a theoretical explanation."

Relevant teams/funders: Emily K. Lindsay, mindfulness dismantling trial researcher; J. David Creswell, Carnegie Mellon University Health and Human Performance Laboratory

Specificity of the Seth formulation: "Must be thoroughly grasped" proposes a necessary condition, stronger than general mindfulness advice; but "thoroughly" and "all areas of life" require preset criteria.

Notes: Participants cannot be reclassified as "not yet truly understanding" after null results, otherwise the necessary condition becomes an unfalsifiable explanation.

Claim: Medical advertising instills fear-based health beliefs in individuals by similar means, and such suggestion is sufficient to cause illness. (personal-reality §660)

Paper

Adjudication experiment: Supplementary question 5: Approximately 800 participants in a 2×2 randomized trial of fear-based/informational advertising × high/low authority cues, matched for factual content; measure susceptibility, severity, expected symptoms, and symptoms after sham exposure, with 3-month follow-up verifying medical records. Compare out-of-sample predictive power between the health belief model and a model incorporating symptom expectancy pathways; new symptoms do not equal new organic lesions. Supplementary question 2 additionally sets up a preregistered replication with approximately 360 participants: interpretation bias training × nocebo induction, adding an emotional Stroop, an independent belief-updating task, and heat pain thresholds, testing the mediating role of bias and expectancy, duration 2 weeks.

Suggested paper title: Health Advertising, Perceived Susceptibility, and Nocebo Responses: A Preregistered Randomized Trial

Core subversion: Symptom effects fit existing nocebo models; only by confirming new organic lesions and excluding behavioral pathways would the assumption that "health risk communication affects health mainly through symptom experience and behavior" be revised.

Relevant teams/funders: Ben Colagiuri, University of Sydney Sydney Placebo Lab; Tessa Rooney, University of Sydney Sydney Placebo Lab; Michael Witthöft, Johannes Gutenberg University Mainz; G. James Rubin, King's College London

Specificity of the Seth formulation: If "causing illness" means discomfort and pain, the prediction overlaps with nocebo effects; if it means confirmable organic lesions, the prediction is stronger but lacks direct support.

Notes: Supplementary question 2 is no longer entirely empty; the 2026 paper is very close to the proposal, but Stroop and implicit association tests are not pure measures of belief; contact Sydney Placebo Lab.

Claim: People with gastric ulcers fear that certain foods cause the disease; this belief establishes a conditioning process through self-hypnosis, and medication acting as a counter-suggestion is part of the same process. (personal-reality §660)

Evidence (Crossref verified):

• Angel Lanas; Francis K. L. Chan (2017). Peptic ulcer disease. The Lancet. https://doi.org/10.1016/S0140-6736(16)32404-7 —— Helicobacter pylori and non-steroidal anti-inflammatory drugs are important causes of peptic ulcer disease; drugs have antibacterial or acid-suppressing effects and cannot be entirely explained as counter-suggestion. Paper
• Tessa Rooney; Louise Sharpe; Jemma Todd; Ben Colagiuri (2026). Cognitive bias modification for interpretation mitigates nocebo hyperalgesia. The Journal of Pain. https://doi.org/10.1016/j.jpain.2025.105646 —— Provides similar evidence that expectancy and conditioned learning alter pain, but the study subjects were not gastric ulcer patients and mucosal damage was not measured. Paper

Adjudication experiment: Approximately 300 endoscopy-confirmed gastric ulcer patients all receive guideline-based treatment, additionally randomly assigned to food threat belief correction, general health education, or matched contact control for 8–12 weeks. Conduct a mild label-crossover trial with a standard meal for those without allergies and explicit contraindications, measuring symptoms and food avoidance separately; ulcer healing assessed by blinded raters according to the clinical review schedule, recording H. pylori eradication, acid-suppressive therapy, and NSAID use. Test whether belief change affects symptoms, adherence, or independent healing differences.

Suggested paper title: Food-Related Expectancies, Symptoms, and Endoscopic Healing in Gastric Ulcer Disease: A Randomized Adjunctive Trial

Core subversion: If beliefs independently alter mucosal healing after controlling for infection, medication, and behavior, this would revise the assumption that "food threat expectancies mainly affect symptoms and eating behavior."

Relevant teams/funders: Francis K. L. Chan, Chinese University of Hong Kong; Angel Lanas, University of Zaragoza; Ben Colagiuri, University of Sydney Sydney Placebo Lab

Specificity of the Seth formulation: "Fearful food—conditioning—symptoms" overlaps with nocebo models; attributing actual drug efficacy to the same suggestion mechanism is stronger than existing models and lacks support.

Notes: Rated contested because the original sentence may refer only to symptom modulation in patients with existing ulcers; if interpreted as ulcers being caused by food beliefs and drugs working solely through suggestion, that strong version should be rated contradicted.

Claim: Seth suggests taking a warm bath before sleep, eating a small amount of food, giving oneself dream suggestions for seven consecutive days, and recording dreams upon waking. (early-sessions-9 §497)

Evidence (Crossref verified):

• Shahab Haghayegh; Sepideh Khoshnevis; Michael H. Smolensky; Kenneth R. Diller; Richard J. Castriotta (2019). Before-bedtime passive body heating by warm shower or bath to improve sleep: A systematic review and meta-analysis. Sleep Medicine Reviews. https://doi.org/10.1016/j.smrv.2019.04.008 —— Warm baths can improve some sleep indicators when appropriately timed, but do not demonstrate increased dream recall, nor do they test the combination of food intake and seven-day suggestions. Paper

Adjudication experiment: Approximately 640 participants in a 2×2×2 randomized design of warm bath × standard small snack × dream recall suggestion; all groups record immediately upon waking to control for the effect of recording itself. 7-day baseline, 7-day intervention, 7-day follow-up; primary outcome is the proportion of mornings with reportable dream content, secondary outcomes are blind-rated number of content units, nocturnal awakenings, and sleep quality, with approximately 80 participants undergoing polysomnography. Preregister the primary comparison of the full combination versus the full control condition and the main effects of each component.

Suggested paper title: Presleep Warming, Food Intake, and Autosuggestion as Determinants of Dream Recall: A Preregistered Factorial Trial

Core subversion: General improvements do not require overturning mainstream findings; only if a reliable combination-specific effect emerges would the assumption that "the effects of these components on dream recall can be explained separately by sleep, arousal, and recording behavior" be revised.

Relevant teams/funders: Michael Schredl, Sleep Laboratory, Central Institute of Mental Health Mannheim, Germany; Shahab Haghayegh, sleep and thermoregulation researcher

Specificity of the Seth formulation: Warm bath, small food portion, seven consecutive days, and waking recording make the recipe relatively specific and testable, but water temperature, food amount, time intervals, and expected gains remain unspecified.

Notes: untested targets the full recipe; bedtime suggestion already has small-scale direct studies; sleep improvement does not necessarily increase dream recall, and this search found no reliable direct evidence that small pre-sleep food intake enhances dream recall.

Claim: Seth suggests imagining, the next morning, seeing the dream record book already filled in and feeling the pleasure of success, in order to promote dream recall. (early-sessions-9 §497)

Evidence (Crossref verified):

• Michael Schredl; E. Doll (1997). Autogenic training and dream recall. Perceptual and Motor Skills. https://doi.org/10.2466/pms.1997.84.3c.1305 —— A 10-week study of 112 trainees reported that autogenic training was accompanied by increased dream recall, but did not isolate "the success imagery of a filled record book." Paper

Adjudication experiment: Approximately 400 participants randomly assigned to success imagery of a filled record book plus pleasure, the same imagery without emotional reinforcement, plain written dream recall intention, or neutral imagery, with all four groups recording immediately and matched for practice time; 7-day baseline, 14-day intervention, and 7-day follow-up. Primary outcome is probability of dream content report upon waking, secondary outcome is independently coded number of details; approximately 80 participants scheduled for fixed sleep-stage awakenings to control for nocturnal awakenings and sleep-stage differences.

Suggested paper title: Prospective Success Imagery and Positive Affect in Dream Recall: A Preregistered Randomized Trial

Core subversion: If success imagery and pleasure show independent incremental effects, this would revise the assumption that "dream recall intention, attention, and recording behavior suffice to explain gains from such training."

Relevant teams/funders: Michael Schredl, Sleep Laboratory, Central Institute of Mental Health Mannheim, Germany; Joel Pearson, University of New South Wales, mental imagery researcher

Specificity of the Seth formulation: The specific success scenario and pleasure are decomposable components, more specific than general "bedtime dream recall intention," but no unique mechanism is proposed.

Notes: Writing more text does not necessarily mean more accurate recall; dream content lacks a full external ground truth, so content reports, detail quantity, and accuracy should be analyzed separately; similar work can be found at Michael Schredl's laboratory.

Claim: Seth encourages Rob to practice "first inner sense" exercises (using the mind's eye to see the other side of objects, imagining walking, etc.). (dreams-projections §2)

Evidence (Crossref verified):

• Joel Pearson; Thomas Naselaris; Emily A. Holmes; Stephen M. Kosslyn (2015). Mental Imagery: Functional Mechanisms and Clinical Applications. Trends in Cognitive Sciences. https://doi.org/10.1016/j.tics.2015.08.003 —— Mental imagery shares partially common representations with perception and can be used in cognitive and clinical research; this does not indicate that imagery can provide veridical information about the unseen reverse side of objects. Paper

Adjudication experiment: First distinguish spatial imagery training from acquisition of unknown information. Approximately 300 participants randomly assigned to object rotation/imagined walking training or time-matched control for 4 weeks; measure judgments of the reverse side of known 3D objects and transfer to new routes, testing ordinary cognitive gains. Separately, under double-blind conditions using reverse-side patterns completely unrelated to the front and randomly selected by an isolated procedure, conduct four-alternative forced-choice judgments, approximately 100 trials per person, without trial-by-trial feedback; preregister primary accuracy rates, participant-level hierarchical models, and independent multi-center replication, project duration approximately 6 months.

Suggested paper title: Visual Imagery Training, Spatial Generalization, and Identification of Concealed Random Targets

Core subversion: Only if identification of randomly concealed targets remains repeatable after excluding information leakage would the assumption that "imagery content derives from existing representations, inference, and available sensory information" be revised.

Relevant teams/funders: Joel Pearson, University of New South Wales; Thomas Naselaris, University of Minnesota; Devin B. Terhune, King's College London

Specificity of the Seth formulation: The original sentence is merely a practice suggestion without specifying what should improve; ordinary spatial imagery has a scientific basis, but if "first inner sense" implies obtaining unknown information, that prediction needs to be explicitly added and cannot be retrofitted onto the original text.

Notes: The reverse side of known objects can be inferred from shape regularities, and imagined walking can draw on existing spatial memory; only independently randomized concealed targets can distinguish ordinary imagery from additional information acquisition.
