The Three-Dimensional NDE Scoring System

A Working Reference for Readers Who Want to Evaluate Cases Themselves

Why a Scoring System at All?

Suppose you pick up a popular book about near-death experiences. The author tells you about a woman who, during her cardiac arrest, floated above her body and watched the surgeon work. She came back to describe instruments she had never seen before in her life. The author treats this story as proof that the soul leaves the body. A few pages later, he tells you about a man who saw a long tunnel of light and felt indescribable peace, and treats that story the same way — proof of the soul.

Now flip to the other side of the bookstore. A skeptic picks up the same two stories and dismisses them with the same wave of the hand. Both are dreams. Both are oxygen-deprived hallucinations. Both are nothing.

Both reactions are too easy. They miss the most important fact about NDE evidence, which is that the cases are not all the same.¹ Some are airtight. Some are loose. Some involve specific, verifiable claims that can be checked against independent records. Some are entirely subjective — beautiful, moving, but evidentially weightless. A serious treatment of the data has to be able to tell these classes apart.

That is what a scoring system is for. It is not magic. It is not a substitute for judgment. It is simply a way to sit down with an NDE account and ask, in an organized way, how strong the evidential case actually is. When you finish, you have a number. The number is rough. But the number forces you to think carefully about three things you might otherwise blur together: how serious the medical event was, how specific the verifiable content was, and how solid the corroboration was.

The scoring system presented here was developed for my doctoral dissertation.² It is not the only such system. The Greyson Near-Death Experience Scale (1983) measures something different — how rich and complete an NDE is as a phenomenological event.³ Kenneth Ring’s Weighted Core Experience Index does similar work.⁴ Those are good tools. But they are not the same kind of tool. Greyson’s scale tells you how much of the standard NDE pattern someone reports. It does not tell you whether their report stands up as evidence for anything beyond the brain.

This appendix lays out a different kind of scale. It asks: How strong is the evidential case here? It treats every NDE as a claim to be tested, not a story to be admired. The system has three dimensions because the evidence comes in three different shapes. You can use it on any case — one from a peer-reviewed journal, one from a popular book, one a cousin shared with you over coffee. The scoring procedure is the same.

I will walk you through the logic, the three dimensions, the threshold categories, and a handful of worked examples. By the end, you should be able to take any NDE account you encounter and form a careful, honest judgment about how much weight it deserves.

The Logic of Three Dimensions

Why three dimensions? Why not just one overall rating?

Because evidence in cases like these comes apart into three independent pieces, and a single overall rating papers over the seams. Imagine a case where a woman reports an NDE during a cardiac arrest with documented loss of brain activity on the EEG — the brain monitor that records the brain’s electrical signals.⁵ The medical context is rock solid. But suppose she reports only that she felt peaceful and saw a vague light. The veridical content is thin. Now imagine a different case: a man with no documented medical crisis at all (he says he “almost died” but the medical records are unavailable) who nonetheless describes, in extraordinary detail, the contents of a hospital storeroom on a different floor — details that are then independently verified. The medical context is weak, but the veridical content is strong.

Which case is better evidence? The answer is “it depends,” and the only way to think clearly about what it depends on is to score each piece separately and then look at the combined picture. A single rating averages away exactly the information you need.

The three dimensions of the scoring system correspond to three honest questions a careful reader has to ask:

One. How serious and how well-documented was the medical event? This is the Medical Context dimension. It asks whether we can be confident the person was actually in a state where ordinary perception was either impossible or severely compromised — cardiac arrest with a flat EEG, deep coma with neurological monitoring, traumatic injury with documented unconsciousness, and so on. A vague “I almost died” without records is at the bottom of this dimension. A documented, EEG-monitored cardiac arrest is at the top.

Two. How specific and how inaccessible-by-normal-means was the content the experiencer reported? This is the Veridical Quality dimension. It asks how detailed and how accurate the experiencer’s claims were, and how impossible it would have been for them to have learned the information through normal channels — overhearing, prior knowledge, lucky guessing, or filling in details after the fact. A vague impression of “a doctor and a nurse and some kind of light” is at the bottom. A specific accurate description of an unusual surgical instrument the experiencer had never seen, in a procedure during which their eyes were taped shut and their ears blocked with audible click-emitting earphones, is at the top.⁶

Three. How well is the case corroborated? This is the Corroboration dimension. It asks whether independent witnesses, contemporaneous medical records, or other documentary evidence support the experiencer’s account — and how soon after the event the corroboration was secured. A single family member’s recollection thirty years after the fact is at the bottom. Multiple medical-personnel witnesses who confirmed details to a researcher within days, with chart timestamps and signed statements, is at the top.

Each dimension runs from 0 to 10. The maximum total is 30. The dimensions are independent in principle, though in practice the strongest cases tend to score high on all three. (That is itself an interesting fact about the data: when you find a clean case, you usually find a clean case.) The scoring is rough, not precise. Two careful evaluators may disagree by a point or two on a given dimension. But careful evaluators rarely disagree by a category. A case at 25 looks different from a case at 8, and most reasonable people will see it.

Dimension 1: The Medical Context Score (0–10)

The first dimension asks about the medical event during which the NDE occurred. The question behind the question is this: Was the experiencer in a state where ordinary sensory perception was reliably impossible or severely impaired? If yes, then an accurate report of distant or shielded events is genuinely puzzling on a physicalist account. If no — if the experiencer might have been somewhat conscious, somewhat able to hear or see, somewhat able to overhear the conversations in the room — then accurate reporting is much less puzzling, because there are ordinary channels through which the information might have reached them.

The dimension does not just measure how close to death the person came. It also measures how well the medical event is documented. A heart attack without records is a story. A heart attack with chart timestamps, EEG strips, and an attending physician’s signed account is a piece of evidence.

Here is how the scale runs.

0 — No medical context. The experiencer reports an NDE-like event during meditation, sleep, or grief, with no medical crisis at all. These cases may be phenomenologically rich and personally important. They are not, on this dimension, evidentially loaded.

1–3 — Minimal context. Some kind of stress or illness was present (a fever, a difficult labor, a fall), but there is no documented loss of consciousness, no documented loss of brain function, and no medical chart. This range also includes self-reported “close calls” without independent verification. The experiencer believed they were near death; the medical record does not show it.

4–6 — Moderate context. A real medical crisis with documented loss of consciousness — a serious car accident, a severe surgical complication, a major hemorrhage, a deep coma — but without continuous neurological monitoring during the experience. We know the person was unconscious; we don’t know exactly what their brain was doing. Many serious NDE cases live in this range.

7–8 — Strong context. Documented cardiac arrest, documented severe anoxic event (oxygen deprivation to the brain), or other major neurological event with chart documentation, witness accounts of the resuscitation, and timing well-established. EEG (electroencephalogram) data may or may not be available, but the medical timeline is clear and the brain was, by ordinary medical standards, in a state inconsistent with normal perception.

9–10 — Exceptional context. Cardiac arrest or analogous event with continuous EEG monitoring documenting absence of cortical (brain-surface) electrical activity during the experience window; or hypothermic circulatory arrest (the body’s temperature deliberately lowered and the blood drained for surgery) with all measurable brain function ceased and audio-evoked potentials confirming auditory processing was off; or another similarly extreme medical scenario in which the brain’s capacity for ordinary perception was, on every available measure, gone. Pam Reynolds’s 1991 standstill surgery is the paradigmatic case at this level.⁷

The scale is not a perfect 11-point gradient; it is meant to be used in tiers. If you can comfortably say of a case “this is between strong and exceptional context,” then 8 or 9 is the right score. If you cannot decide between “moderate” and “strong,” pick 6 or 7 and move on.

One word of caution. A high medical context score is a necessary condition for a strong evidential case but not a sufficient one. A patient might be in documented cardiac arrest with a flat EEG and report only that she felt peaceful and saw her grandmother. That is a 9 on Medical Context and possibly a 1 on Veridical Quality. The strong context tells you the experience cannot be a simple awake-and-listening case; it does not tell you that the content carries any informational weight.

Dimension 2: The Veridical Quality Score (0–10)

The second dimension is the heart of the system. It measures the part of the experience that can do evidential work — the specific, verifiable claims about the external world that the experiencer makes.

Three sub-questions go into this score.

First: How specific is the claim? “A woman in white” is vague. “A red-haired woman wearing a green surgical scrub top and a stainless-steel watch on her left wrist who said, ‘Get me the longer needle’” is specific. Specificity is what separates a guess from a perception. Anyone can guess that there were doctors in an emergency room. Almost no one can guess the brand of an unusual surgical instrument or the exact words spoken at a specific moment.

Second: How accurate is the claim? Specificity without accuracy is meaningless. A confidently specific but wrong claim is more damning than a vague one, because it shows the experiencer was filling in details rather than perceiving them. Veridical Quality scoring requires that the specific claims actually match what happened.

Third: How inaccessible by ordinary means was the information? The strongest veridical content is information the experiencer could not have known beforehand and could not have learned afterward through normal channels. Accurate descriptions of events occurring during clinical death, in rooms physically distant from the body, observed from spatial perspectives the body could not have occupied (above the operating table, looking down) — these are the gold standard.⁸

Here is the scale.

0 — No veridical content. The experience is entirely subjective — emotions, thoughts, images of light, encounters with figures who cannot be independently identified or verified. This dimension is silent on whether the experience was real or meaningful. It says only that the experience does not, by itself, contain anything that can be checked against the external world.

1–3 — Minimal veridical content. The experiencer reports general descriptions of the medical setting that match what one would expect — doctors, nurses, machines, perhaps a vague sense of the room layout. These details could plausibly come from prior knowledge, popular media, or general inference. There may be a detail or two that is mildly impressive, but most of the report could have been generated by anyone who has ever watched a hospital television show.

4–6 — Moderate veridical content. The experiencer reports specific details that match the actual events — names of personnel, particular conversations, identifiable equipment, specific actions taken during the resuscitation — that go beyond what general inference would supply. There are details that strain the “they could have just guessed” explanation. But there is no single observation that decisively rules out alternative pathways for the information.

7–8 — Strong veridical content. The experiencer reports specific accurate details that are highly unlikely to have been guessed, inferred, or obtained through normal means. Common patterns at this level include: accurate description of unusual or specialized equipment the experiencer had never seen; accurate verbatim recall of conversations during the medical event; accurate description of events in physically distant rooms (the waiting room, another floor of the hospital); accurate identification of family members’ specific actions occurring during the experience window. Multiple such details typically appear together.

9–10 — Exceptional veridical content. The experiencer reports specific accurate details that are essentially impossible to explain by any normal means — observations made during periods of documented brain shutdown, observations made by congenitally blind experiencers (who have no visual neural architecture for the brain to hallucinate through), observations from spatial perspectives the body could not have occupied combined with simultaneous accurate observations of events in other rooms, accurate identification of deceased relatives the experiencer did not know had died at the time of their experience.⁹

The Veridical Quality score is the dimension where serious cases distinguish themselves. Many NDEs — even profound and life-changing ones — score 0 on this dimension. They are not less real for that. They simply do not, by themselves, generate evidence of the kind this scoring system is built to identify. The strong cases — Pam Reynolds, Maria’s tennis shoe, Vicki Umipeg, Al Sullivan, the AWARE cases — all score in the 7–10 range here.¹⁰

Dimension 3: The Corroboration Score (0–10)

The third dimension asks whether the case is backed up. An experiencer’s testimony is one piece of evidence. An experiencer’s testimony plus contemporaneous medical records, plus signed witness accounts, plus on-the-record interviews with the medical staff who were present, is something else.

This dimension matters because human memory is fragile and stories grow in the telling.¹¹ A specific accurate detail reported to a researcher within a week of a cardiac arrest, before the experiencer had any chance to learn the details from the medical record or family members, is much stronger evidence than the same detail reported in a memoir thirty years later. The Corroboration dimension tries to capture this.

Three sub-questions, again.

First: How independent is the corroboration? Family confirmation is helpful but limited — family members may have heard the story many times and may unconsciously align their memories with the experiencer’s version. Medical-personnel confirmation is stronger because the personnel were typically not invested in the story and have professional reasons for accuracy. Documentary corroboration (chart timestamps, EEG strips, surgical records) is strongest of all because it is unaffected by anyone’s memory.

Second: How contemporaneous is the corroboration? Was the experiencer interviewed and the witnesses queried within days or weeks of the event, or only years later? Real-time documentation is the gold standard. Late documentation can still be valuable, but cryptomnesia (forgotten knowledge surfacing as if it were new) and confabulation (innocent retrospective filling-in) become serious concerns the longer the gap.

Third: How many independent sources support the case? A single witness with a single document is one thing. Multiple medical personnel, chart timestamps, family-members’ same-day reports, and (in the strongest cases) prospective study protocols designed to capture exactly this kind of evidence are quite another.

Here is the scale.

0 — No corroboration. The case rests entirely on the experiencer’s testimony, with no medical records, no witness accounts, and no documentation of any kind. Cases at this level may still be theologically or pastorally meaningful. They cannot do evidential work.

1–3 — Minimal corroboration. Family-only confirmation, late documentation, or single-source reports without independent verification. The story is consistent with what others remember, but no independent records exist to anchor it.

4–6 — Moderate corroboration. At least one independent witness (typically medical personnel) who confirms specific details, plus some contemporaneous documentation (chart entries, dated medical reports). The corroboration is sufficient to rule out outright fabrication and to anchor the timeline, but does not yet meet the rigorous standards of prospective NDE research protocols.

7–8 — Strong corroboration. Multiple independent witnesses, contemporaneous medical records, and (in the best cases) on-the-record interviews of medical staff conducted by trained researchers within a relatively short window of the event. The case has been investigated, not just reported. Specific veridical claims have been checked against records and against witness recollections, and the checks have come back clean.

9–10 — Exceptional corroboration. Prospective study protocols (in which patients are interviewed promptly after resuscitation, with medical staff queried independently); peer-reviewed publication with full documentation; corroborating EEG and other neurophysiological data; and, ideally, multiple researchers who have independently examined the case file and arrived at consistent conclusions. The AWARE I and AWARE II studies, the van Lommel Lancet prospective study, and the Sabom Atlanta studies are the methodological models at this level.¹²

One observation worth pausing on. The Corroboration dimension is the easiest to lose ground on as time passes. A case that was a 9 in 1991 may be a 6 in 2026 if the records have been lost, the witnesses have died, and the experiencer’s account is the only surviving document. Researchers working with older cases sometimes find that what was once heavily documented is now only sketchily so. This is one reason why the contemporary prospective studies (van Lommel, Parnia, Sartori) are so valuable: they capture the evidence at full strength while the records are still alive.

Adding It Up: The Five Threshold Categories

The three dimensions sum to a maximum of 30. The dissertation grouped cases into five threshold categories based on the combined score.¹³

None (0–5 total). No meaningful evidential weight. The case may be a perfectly genuine NDE, but it does not, by itself, support any inference about consciousness, the soul, or the boundary of death. A vague subjective experience reported by someone with no documented medical crisis and no corroboration falls here.

Minimal (6–12). Weak evidential weight. The case has some features that gesture toward veridical content but is not strong enough to do meaningful work in a cumulative argument. Most popular-press NDE accounts that lack medical documentation fall in this category.

Moderate (13–18). Meaningful evidential weight. The case has documented medical crisis, some genuinely veridical content, and at least moderate corroboration. A handful of moderate cases would not by themselves settle anything; a thousand of them tells you something.

Strong (19–24). Substantial evidential weight. Each case at this threshold can stand on its own as a serious challenge to the strict physicalist prediction. A reader encountering even one or two clean Strong cases should find the easy “all hallucination” explanation harder to maintain.

Exceptional (25–30). Decisive single-case evidential weight. These are the cases where every dimension is clean: documented medical crisis with continuous monitoring; specific veridical content that could not have been obtained by ordinary means; multiple independent corroborations confirmed by trained researchers. Pam Reynolds is the standard example. Vicki Umipeg, in the congenital-blindness category, is another.¹⁴

In the dissertation’s analysis of 5,278 NDE cases, 1,618 (30.7 percent) met the threshold for Strong or Exceptional evidence.¹⁵ The remaining 69.3 percent were not useless — many of them informed the phenomenological and consistency-of-pattern arguments developed elsewhere in this book — but they did not bear the weight of the central evidential case for substance dualism. That weight is carried by the 1,618.

One thing to notice. The thresholds are not evenly spaced across 0–30. Reaching Strong (19) requires that the case be solid on at least two dimensions and not weak on the third. Reaching Exceptional (25) requires near-maximal scoring across all three. This is intentional. The thresholds reflect not arithmetic but the kind of evidential work each level can do. A 19 is a case you can stand behind. A 25 is a case you can build on.¹⁹

Worked Examples: Five Cases at Five Thresholds

The scoring system is easier to understand by example than by abstract description. Here are five cases at the five threshold levels.

Exceptional (25–30): The Pam Reynolds Case

In August 1991, Pam Reynolds underwent hypothermic circulatory arrest at the Barrow Neurological Institute for the removal of a basilar aneurysm (a bulge in a major artery at the base of the brain).¹⁶ Her body temperature was lowered to about 60°F. Her blood was drained from her body. Her brainstem auditory evoked potentials were continuously monitored using earphones that emitted loud, regular clicks. All measurable cortical activity ceased. By every available medical measure, she was dead.

During the procedure, Pam reported a vivid out-of-body experience. She described the surgical instruments, including the unusual pneumatic Midas Rex bone saw with a distinctive top assembly that she had never seen and that did not look like an ordinary surgical instrument. She quoted conversation between the surgical staff. She described which staff members were present and what they were doing. After her recovery, every specific veridical detail was confirmed by the surgical team.

Medical Context: 10. Hypothermic standstill with cessation of all measurable brain activity, continuous EEG and BAEP (brainstem auditory evoked potential) monitoring, perhaps the most thoroughly documented near-death medical scenario in the literature.

Veridical Quality: 9. Multiple specific accurate details — the bone saw, the conversations, the staff actions — all unlikely to have been obtained by normal means; the patient’s eyes were taped shut and her ears were filled with click-emitting earphones loud enough to mask normal speech.

Corroboration: 9. Sabom’s investigation included on-the-record interviews with the surgical team, who confirmed the specific details. Medical records and surgical procedures are documented. Some questions remain about precise timing of the OBE within the surgical timeline, but the central veridical claims are confirmed.

Total: 28. Exceptional.

Strong (19–24): The Maria’s Tennis Shoe Case

In April 1977, a Hispanic migrant worker named Maria suffered a severe heart attack and was admitted to Harborview Medical Center in Seattle. During a subsequent cardiac arrest, she had an NDE in which she found herself outside the hospital, looking at a tennis shoe perched on a third-floor window ledge on the north side of the building. She described the shoe in detail — worn, with a shoelace caught under the heel, on a ledge to which she had no normal access. After her recovery, she told her social worker, Kimberly Clark Sharp, who eventually went to investigate. The shoe was there, exactly as Maria had described.¹⁷

Medical Context: 7. Cardiac arrest with documented loss of consciousness, hospital admission, witnessed resuscitation. The continuous-EEG documentation that would push this to Exceptional was not in place.

Veridical Quality: 9. The location and configuration of the shoe was extraordinarily specific and could not, by any plausible account, have been obtained through Maria’s ordinary perceptual access — she had been brought to the hospital from elsewhere, the ledge was not visible from inside the building, and the specific details (the lace caught under the heel) require a viewing angle no walking observer could have had.

Corroboration: 6. The case was investigated by Sharp, who eventually published her account, and the shoe was independently observed. Some later researchers have raised questions about whether all of the specific details were verifiable in the way originally claimed, and re-investigation has muddied some particulars. The case is solid but not pristine.

Total: 22. Strong.

Moderate (13–18): A Composite Cardiac-Arrest Case

The dissertation database contains hundreds of cases at the Moderate level. A typical example: a sixty-eight-year-old woman experiences a cardiac arrest in a hospital cardiac care unit. Resuscitation is documented in the chart, with timestamps spanning approximately seven minutes. She subsequently reports a coherent NDE in which she watched her resuscitation from above, accurately described the actions of two of the four medical personnel present, and reported a brief conversation that one of the personnel later confirmed had occurred. She did not, however, report any unusual or surprising detail; the conversation she repeated was the kind of routine call-and-response familiar from any cardiac code.

Medical Context: 7. Documented cardiac arrest with chart timestamps; EEG monitoring not in place during the arrest itself.

Veridical Quality: 5. Several accurate details, but each within the range of what general inference and post-event reconstruction could supply. The single confirmed conversation is the strongest element but is not, by itself, the kind of unusual content that resists alternative explanation.

Corroboration: 4. One staff member confirmed details after the fact; chart documentation supports the timeline; the case was not subjected to formal prospective protocol.

Total: 16. Moderate.

One Moderate case proves nothing. A thousand Moderate cases — which the database contains — is itself a substantial body of evidence, particularly when paired with the Strong and Exceptional cases for which alternative explanations have been carefully canvassed and rejected.²⁰

Minimal (6–12): A Self-Reported Close Call

A fifty-year-old man, several years after the fact, describes an NDE that occurred during a serious illness in his thirties. He recalls feeling himself separate from his body, drifting toward a light, encountering a deceased grandfather, and feeling a sense of profound peace before being “pulled back.” He recovered. The medical records from the illness no longer exist. No witnesses confirm a close-call moment. The man’s testimony is sincere and detailed, but no piece of it can be checked against external evidence.

Medical Context: 3. Self-reported serious illness; no documentation; no clear identification of a moment at which the brain’s capacity for ordinary perception was compromised.

Veridical Quality: 1. No specific verifiable claims about the external world. The encounter with the grandfather, while emotionally meaningful, is not an evidential claim that can be tested.

Corroboration: 2. Some family confirmation that the man was very ill at the time; nothing further.

Total: 6. Minimal.

Such a case may be perfectly genuine. The man may have had a real NDE. But his testimony cannot, by itself, do evidential work. It contributes to phenomenological pattern arguments — the consistency-across-cases arguments developed in Chapter 9 — but it does not contribute to the cumulative veridical case.

None (0–5): A Subjective Spiritual Experience

A woman reports an experience during deep meditation in which she felt herself rise out of her body, encounter a being of light, and receive a message about the meaning of her life. There was no medical event. She was not ill. The experience occurred entirely in the context of spiritual practice. She remembers it vividly and considers it the most important moment of her life.

Medical Context: 0.

Veridical Quality: 0. No specific verifiable claims about the external world.

Corroboration: 1. A few people heard her describe the experience shortly afterward.

Total: 1. None — for evidential purposes.

Two clarifications matter. First, “None” on the evidential scale does not mean the experience was unreal. It means the experience cannot, by itself, be used as evidence in a careful argument about the boundaries of consciousness. The woman’s testimony may be a precious record of genuine spiritual encounter. It is simply not a candidate for the kind of empirical work this scoring system is built to support.

Second, this category illustrates why the system focuses tightly on veridical evidence rather than on phenomenology. The Greyson NDE Scale, applied to the same experience, might score it quite high — the woman reports peace, body separation, a being of light, deep meaning. The phenomenology is rich. The evidence, on this dimension, is not.

A Practical Guide for Readers

How should you use this scoring system when you encounter an NDE account in a popular book, a sermon illustration, a friend’s testimony, or a documentary?

A few suggestions, drawn from years of working with cases.

Begin with the medical context. Before you ask what the experiencer reported, ask what the medical situation was. Was there documented loss of consciousness? A cardiac arrest? A coma? Was the documentation contemporaneous with the event, or has it been reconstructed years later? If you cannot establish the medical context, you cannot score the case higher than the documentation will support, no matter how striking the content of the report. A 10 on Veridical Quality with a 1 on Medical Context is much weaker than its raw score suggests.

Be skeptical of perfect-sounding stories. The strongest cases in the literature are not the smoothest. They have wrinkles. They have unresolved questions about timing. They have witnesses who confirm some details but not others. Real cases look like real cases. A story in which every element lines up perfectly, with no loose ends, with the experiencer remembering everything in vivid detail decades later, is more often a product of retelling than a record of what happened. Memory is not a tape recorder. The closer to the event the documentation, the more reliable.

Pay attention to what the experiencer could plausibly have known. Many NDE accounts contain accurate details that, on inspection, the experiencer could have learned through ordinary channels — overheard conversations during the recovery period, comments from family members, exposure to medical television shows, prior knowledge of the procedure.²¹ The veridical-quality score must reflect this. If a detail could have been picked up by ordinary means, it gets less weight than a detail that could not.

Treat blind cases with extra care. The congenitally-blind NDE cases occupy a special position in the evidential landscape because the brain has no normal visual neural architecture for hallucination to draw on.¹⁸ A specific accurate visual description from a person blind from birth is, on the strict physicalist account, essentially inexplicable. Chapter 11 develops this case at length.

Distinguish the evidential argument from the spiritual significance. A case that scores 0 on this scale may be deeply spiritually meaningful. A case that scores 28 may be theologically uneven. The scoring system tracks one specific question: how strong is the empirical case? It does not track theological discernment, pastoral importance, or spiritual depth. Those are real and important features of NDE accounts, but they are different features. A separate framework for theological discernment is developed in Appendix C.

Resist the temptation to settle the question on a single case. The veridical NDE evidence is a cumulative argument. Even an Exceptional case has alternative-explanation pathways that a determined skeptic can develop.²² The strength of the case lies in the number and consistency of the strong cases, the convergence of independent investigators, the failure of physicalist alternatives to account for the patterns at scale. A reader who treats Pam Reynolds as the whole argument will eventually run into a sophisticated objection and feel the ground move. A reader who understands Pam Reynolds as one of more than 1,600 strong cases will not.

The Limits of Any Scoring System

One final note, which honest scholarship requires.

This scoring system is a tool. It is not the territory. It is not the truth. It is a way of organizing your thinking about cases — a heuristic, not a verdict. Two careful evaluators applying the system to the same case will sometimes disagree. The boundaries between thresholds are not metaphysical lines; they are working approximations chosen to reflect the kind of evidential work each level can do.

The system also cannot answer questions it was not designed to answer. It cannot tell you whether a particular NDE account is theologically reliable. It cannot tell you whether the being of light that an experiencer encountered was Christ, or an angel, or a projection of the mind’s deepest hopes. It cannot tell you whether the soul that left the body during a cardiac arrest will, after the long sleep of death, see Christ face to face. Those are theological questions, and they require theological tools.²³

What the scoring system can do is help you think clearly about a single, narrow, important question: How strong is the empirical case in this particular instance? When you have an answer to that question, you have a piece of evidence to set on the scale. You do not yet have a metaphysics. You do not yet have a doctrine of dying. But you have something. You have a brick. And the case for substance dualism, the conscious intermediate state, and the historic Christian theology of dying that Chapter 23 develops is built, finally, out of bricks.

The remaining appendices extend the work begun here. Appendix B annotates the major bodies of literature on NDE research, substance dualism, Christian physicalism, the long-hope tradition, and the pastoral theology of dying. Appendix C develops the framework for Christian discernment of NDE content — a question distinct from, and complementary to, the evidential scoring developed here. Appendix D answers the major Christian-physicalist responses to the dissertation’s evidence. Appendix E presents a representative sample of cases at each threshold level, scored in detail using this system.

The scoring system is, in the end, a way of being honest with the evidence. The evidence deserves nothing less.
