What Counts as Veridical

Defining Terms with Care

In August 1991, a thirty-five-year-old woman named Pam Reynolds was wheeled into an operating room in Phoenix, Arizona, for a surgery so dangerous that her surgeons had to stop her body from working in order to save her life. She had a giant aneurysm at the base of her brain — a balloon of weakened artery wall threatening to rupture. To repair it, the team used a procedure called hypothermic cardiac arrest. They cooled her body to 60 degrees Fahrenheit. They drained the blood from her head. They stopped her heart. Small molded earphones were taped into her ears, clicking at one hundred decibels — louder than a chainsaw — to monitor whether her brainstem was responding to sound. By every measurement modern medicine has, she was as close to dead as a living person can be. Her electroencephalogram, or EEG (the machine that reads the brain's electrical activity), was flat. Her brainstem was silent. Her body had no pulse.¹

And during all of this, she was watching.

Pam later described the bone saw the surgeon used to open her skull. Not just that there was a saw, but its specific shape — a small pneumatic tool with interchangeable blades stored in what looked like a socket-wrench case. She quoted a remark made by the cardiac surgeon about her femoral arteries being too small. She named the song playing in the operating room when she was being closed up. None of these details were available to her through her physical senses. Her ears were plugged and clicking. Her eyes were taped shut. Her brain was offline. Yet the surgical team confirmed every detail.²

Now consider a different kind of report. A man tells his pastor that he “died” for a few seconds during a fainting spell, met Jesus in a meadow, and came back. He cannot say what hospital he was in. There is no record of cardiac arrest. The story was first told three years after the event. No witness can place him in any state more serious than a brief loss of consciousness on his living-room floor.

Both of these are sometimes called “NDEs.” Both may be deeply meaningful to the people who had them. But they are not evidentially equivalent. Not even close. The difference between them is what this chapter is about.

Why the Definition Matters

The word at the center of the next several chapters is veridical. It comes from the Latin veridicus — “truth-telling.”³ A veridical perception is one that turns out to match the actual world. If a man on the operating table reports seeing a tennis shoe on a third-story ledge during his cardiac arrest, and a hospital social worker later climbs out and finds a tennis shoe on that ledge, his perception was veridical. If he reports seeing his deceased grandmother in a meadow, that experience may be many things — comforting, theologically significant, deeply real to him — but it is not veridical in the technical sense, because there is no third-party measurement that can confirm or deny it.

This distinction is not a quibble. It is the load-bearing wall of the book's evidential argument. The case for substance dualism — for the claim that the mind is something more than the brain's electrical chatter — does not rest on every NDE ever reported. It rests on a specific subset: the veridical ones. These are the cases the physicalist account cannot reach, because they involve accurate information acquired during a medical state in which accurate information acquisition should be impossible.

I want to walk the reader carefully through what counts and what doesn't. The case-file chapters that follow this one — distant-observation cases, blind-NDE cases, cardiac-arrest cases, Peak-in-Darien cases — will use the framework laid out here. If we get the methodology right at the start, the strength of the cases that follow will be visible at a glance. If we don't, we will end up either dismissing strong evidence as anecdote or overclaiming weak evidence as proof. Neither serves the truth.

Four Criteria for a Veridical NDE

Across fifty years of research, the field has converged on four working criteria for treating an NDE perception as veridical. They are not arbitrary. Each one closes off a specific way the report could be wrong.⁴

First, the information must be objectively verifiable. That is, there has to be some external fact — an event, a location, a piece of medical equipment, a conversation, a person's actions — that can be checked against the experiencer's report. “I felt a sense of peace” is real and important, but it is not externally verifiable. “The anesthesiologist said he was concerned about my femoral arteries” is. The first kind of report belongs to phenomenology. The second kind belongs to evidence.

Second, the information must have been inaccessible through ordinary sensory means. If a patient's eyes were open, if she could hear conversations in the room, if a relative had told her the night before what surgery she would be undergoing — those are all normal channels of information. They have to be ruled out. The strong veridical cases involve patients with eyes taped shut, ears plugged, and brains in documented electrical silence; they involve perceptions of events occurring in rooms the patient never entered, on shelves the patient never approached, or in conversations held while the patient was clinically dead.

Third, the information must be independently corroborated. A single uncorroborated claim, however vivid, is not enough. Strong cases have a paper trail: nurses' notes, anesthesia records, witness interviews conducted by trained researchers, sometimes video. The corroboration has to be external to the experiencer.⁵

Fourth, plausible alternative explanations must be ruled out. Could the patient have overheard a comment before losing consciousness and unconsciously stitched it into her later report? Could she have read her medical records afterward and woven the details in? Could she have made a lucky guess? In rigorous case studies, each of these alternatives is examined and shown to be implausible before the case is treated as evidentially strong.

These four criteria do a lot of work. They are why the Pam Reynolds case is in nearly every serious treatment of NDE evidence, and why the “I died on my living-room floor and met Jesus in a meadow” story, however meaningful to the man who had it, simply cannot bear the same evidential load.

The Three-Dimensional Scoring System

The dissertation that grounds this book set out to evaluate not a handful of cases but thousands. Working through 5,278 reports drawn from the scholarly literature and from the two largest publicly accessible databases — the Near Death Experience Research Foundation (NDERF) and the International Association for Near-Death Studies (IANDS) — I needed a way to assign each case a defensible evidential weight.⁶ Reading the existing literature, I noticed something. The standard tools, like the Greyson NDE Scale, were superb at measuring how rich and complex an NDE was. But they were not designed to measure how strong it was as evidence. Phenomenological richness and evidential weight are not the same thing.

So I built a three-dimensional scoring system. Three axes, each running from 0 to 10. Maximum possible score: 30.⁷

(A) Medical Context Score (0–10). This axis measures how serious and how well-documented the medical crisis was. A patient in documented cardiac arrest, with EEG monitoring showing flat electrical activity, attended by a multi-person resuscitation team whose actions appear in time-stamped records, scores at the top. A patient with a vague self-reported “I almost died” — no hospital admission, no medical records, no witnessed crisis — scores at the bottom. The middle is populated by cases of severe trauma, drug overdose, anaphylaxis, or surgical complication where the medical record is partial.

(B) Veridical Quality Score (0–10). This axis measures the clarity, specificity, and inaccessibility of the perceived information. A specific identification of a unique surgical instrument used during a sealed-skull procedure scores at the top. “I had a sense that something happened in the room” scores at the bottom. Between those poles lie the many cases where the perception is partially specific, partially general — accurate enough to be striking but not so detailed as to rule out every alternative explanation.

(C) Corroboration Score (0–10). This axis measures the quality of the independent witness testimony and documentary evidence. Multiple medical-personnel witnesses with contemporaneous notes, structured interviews conducted by trained researchers, and time-stamped records score at the top. A single family member's recollection many years after the event scores at the bottom.

The combined score sorts cases into five thresholds: None (no genuine evidential content), Minimal (suggestive but weak), Moderate (suggestive and reasonably documented), Strong (well-documented with multiple lines of evidence), and Exceptional (the gold-standard cases — Pam Reynolds, Vicki Umipeg, the AWARE-I veridical case, and a small set of others). The full scoring methodology, with operational definitions and worked examples, appears in Appendix A. What matters here is the principle behind it: not every NDE counts equally, and the strong cases can be identified by criteria that anyone, skeptic or sympathizer, can apply.

Why Not Just Use the Greyson Scale?

The reader who has spent any time in NDE literature may wonder why I built something new instead of using the field's standard tool. The Greyson NDE Scale, developed by University of Virginia psychiatrist Bruce Greyson in 1983, is the workhorse of the field. It asks the experiencer sixteen questions about specific phenomenological elements — time distortion, accelerated thought, sense of unity with the universe, encounters with mystical beings, and so on — and produces a score out of 32. Anyone scoring 7 or higher is treated as having had a “genuine” NDE for research purposes.⁹

The scale is excellent for what it does. But what it does is measure the internal richness of an experience — how many of the classic NDE elements were present, how vivid they were. It does not measure whether the experience contains any externally verifiable content. A woman could score a perfect 32 by reporting a deeply mystical experience and yet not produce a single piece of veridical evidence. Conversely, a man could score only an 8 — minimal phenomenology — but happen to have observed and accurately reported a specific event in another room while his EEG was flat. For the question this book is asking, the second case is by far the more important.

The same is true of Kenneth Ring's earlier Weighted Core Experience Index from 1980. Both scales measure phenomenology. The dissertation's scoring system measures evidence. The two are complementary, not competing, and the strongest cases — Pam Reynolds, the Vicki Umipeg case, the AWARE-I cardiac arrest case — score high on both.¹⁰

What Counts and What Doesn't

It helps to be concrete. Here is the kind of case that counts as strong veridical evidence: a documented cardiac arrest, with EEG monitoring confirming the absence of cortical activity; a coherent NDE report given within hours or days of the event; specific accurate descriptions of resuscitation procedures that the patient could not have observed normally; verification of those details by multiple medical staff; a contemporaneous chart that lines up with the report; the patient interviewed by a researcher who knew nothing of the surgical record at the time of interview, to prevent contamination of the testimony.

And here is the kind of case that does not count as veridical evidence — though it may count for other purposes. A vivid encounter with a being of light, accompanied by deep peace and a sense of unconditional love, but without any externally verifiable content. A felt presence of a deceased grandparent. A sense of having traveled somewhere indescribable. None of these are evidence for the metaphysical claim that the mind operates apart from the brain. They may be theologically significant. They may be life-transforming. They may even be true. But they cannot do the work of proof in the strict sense, because there is no external check.¹¹

I think it is worth distinguishing three classes of NDE evidence that often get blurred together. Veridical evidence is the strongest evidential class — the cases that contain externally verifiable content acquired under conditions where verification was supposed to be impossible. Phenomenological evidence — the consistency of NDE reports across cultures, across decades, across age groups — is a different kind of argument, powerful in its own way, owned by the next chapter. Transformational evidence — the deep and lasting personality changes typical of NDErs after their experience — is significant but evidentially distinct from either of the other two.¹² The book's strong case is built primarily on the veridical class. The phenomenological and transformational classes support that case but cannot carry it alone.

The Standard Objections

The skeptical literature has produced a recognizable family of objections to veridical NDE reports. Each deserves a fair hearing, because each has bite for some cases — but none of them holds for the strongest cases.

“It's coincidence.” Patients in or near death sometimes guess correctly about events around them; we should expect the occasional lucky hit. Granted. But the strong cases involve multiple correct elements — specific instruments, specific quoted speech, specific actions of named individuals — all converging in a single report. The probability of a lucky multi-element hit during documented cardiac arrest is vanishingly small. Coincidence works as an explanation for one detail. It does not scale to ten.

“It's cryptomnesia.” The Greek-rooted term means “hidden memory”: the patient may have absorbed the information before losing consciousness, perhaps from staff conversation in the pre-op area, then forgotten the source and reproduced the content as if it were a perception during the arrest.¹⁴ This is a real phenomenon, and it is plausible for some weakly documented cases. But the strong cases rule it out by what I will call the temporal-impossibility criterion: the perceived event occurred during the period of clinical death, after the patient had already lost consciousness and could not have absorbed the information beforehand. Pam Reynolds could not have heard her surgeon's comment about her femoral arteries before the comment was made. The comment came during the arrest.

“It's researcher bias and selection effects.” The published veridical literature, the objection runs, is heavily filtered. Researchers select the impressive cases, drop the misses, and present a misleadingly tidy pattern. This is the most serious of the standard objections, because some filtering is undeniable. But the dissertation addressed it directly. Half the dataset (the 4,446 cases drawn from the NDERF and IANDS online databases) is essentially unfiltered: anyone can submit, and submissions are not screened for evidential value before publication. If selection bias were producing the apparent veridical pattern, the unfiltered cases should not show it. They do.¹⁶ The same statistical signature — high veridical content correlating with severe medical crisis — appears in both halves of the dataset.

What the Methodology Establishes

Step back and consider what this scoring framework can and cannot do. It cannot tell us whether any individual NDE is “true” in some final theological sense — that is a different question, addressed in Chapter 30 on Christian discernment. It cannot tell us how to interpret the content of an NDE for a particular dying person. It cannot replace clinical judgment, pastoral wisdom, or scriptural reflection.

What it can do is sort the empirical wheat from the empirical chaff. Out of 5,278 cases, fewer than a third — 1,618 — meet the Strong or Exceptional thresholds. The remaining two-thirds are not necessarily false; many are likely real experiences. But they cannot do the heavy evidential lifting. The 1,618, on the other hand, can. They constitute a body of well-documented, independently corroborated, methodologically rigorous data of a kind that would be taken seriously in any other empirical field.

That is, I think, the right place to set the bar. Set it any lower and we are in the territory of credulity, where every story counts and the field collapses into anecdote. Set it any higher and we are in the territory of unfair skepticism, where no amount of evidence could ever count and the bar becomes a way of refusing to hear what the data say. The three-dimensional system tries to set the bar at the place a working medical researcher would set it for any other unusual phenomenon.

I want to be honest about its limits. The scoring system is one framework, not the only possible one. Different researchers might weight the dimensions differently. Some cases sit ambiguously between thresholds. Reasonable people can disagree about how to score a particular report. But the basic structure — separating medical context, veridical quality, and corroboration into distinct dimensions, then combining them — captures something the older phenomenological scales miss. And the structure is robust enough that the broad findings are not changed by small adjustments. Even with stricter thresholds, the strong-and-exceptional cases form a substantial body of evidence. Even with looser ones, the same patterns hold.

Why This Matters

For the pastor at a hospital bedside, the chaplain in an ICU, the Christian wrestling with a loved one's NDE report, the methodology of this chapter has a practical edge. When someone tells you about an experience, you can listen with both warmth and discernment. You do not have to choose between dismissing it and accepting every detail uncritically. You can ask the kind of questions a careful researcher would ask. What was the medical context? Could the perception have come through ordinary channels? Has anyone else corroborated what you saw or heard? Does the timing rule out the obvious alternative explanations? You can hold the experience as meaningful even if it does not meet the strict veridical bar — and you can recognize, when a case does meet that bar, that you are looking at something the standard physicalist account simply cannot explain.

The methodology is not a wall between us and the dying. It is a way of taking their reports seriously, of refusing both the easy yes of credulity and the easy no of dismissal. The strong cases will hold up under any honest scrutiny. The weak ones will not. Christian witness has nothing to fear from careful discernment, and a great deal to gain from it.

The chapters ahead will draw on this framework constantly. When I describe Pam Reynolds, or the social worker who saw the tennis shoe on the third-floor ledge, or the cardiac surgeon's patient who watched him “flap his elbows” during a triple bypass, I will be pointing the reader toward cases at the top of the scale. When I name limitations or weaker reports, the reader will know how to weigh them. The scoring framework is the apparatus that lets the rest of the book do its work.

One more thing. The closer we look at strong veridical NDEs, the more they resist the categories the materialist worldview wants to put them in. They are not anecdotes, not folklore, not pious sentiment. They are reports of accurate perception during clinical death — and the cumulative weight of them, taken honestly, is one of the more striking empirical patterns in contemporary medical research. The chapters that follow will let those cases speak. The framework set down here is what allows their voices to be heard clearly.
