The Poltergeist and the Nuclear Plant: What Three Centuries of Institutional Documentation Actually Show

There is a through-line running from a confiscated drum in 1661 to a diamond-shaped object over a nuclear weapons facility in 2015, and it is not what you might expect. It is not evidence of the supernatural. It is not evidence of extraterrestrial intelligence. It is something stranger and more interesting than either: it is the persistent, centuries-long record of institutions taking anomalous reports seriously enough to write them down.

Let me explain what I mean.

Joseph Glanvill was a Fellow of the Royal Society — the Royal Society, the institution that was at that moment in history inventing what we now call empirical science — and he traveled to John Mompesson's house in Tedworth to investigate a poltergeist. He wrote it up. He published it. This was not fringe behavior in 1662; this was a serious man doing what serious men did, which was go look at things and record what he found. The Royal Society's founding motto was *nullius in verba* — take nobody's word for it. Glanvill was following that instruction.

The Worksop case of 1883 was investigated by the newly formed Society for Psychical Research, which included among its founders some of the more rigorous minds of Victorian science. A police officer was among the witnesses. The Cideville case of 1850 went to actual court — it was, the documents note, practically a trial for witchcraft, conducted with legal formality and sworn testimony. The Fox sisters' rappings were examined by the Seybert Commission, a body convened by the University of Pennsylvania.

And now, in 2026, the Pentagon has released its fourth tranche of UAP documents through a program called PURSUE, and among the files is a detailed incident report about security officers at the Pantex nuclear weapons facility — the facility where the United States assembles and dismantles its nuclear arsenal — chasing a slow-moving, diamond-shaped object that triggered a lockdown. The report does not claim to know what the object was. It says, in official language, that the case is unresolved because investigators could not collect enough information to make a confident identification.

The same words, essentially, that Glanvill wrote about Tedworth.

What strikes me about this pattern is not the phenomena themselves — I have no idea what was happening at Mompesson's house, and neither does anyone else — but the institutional response to them. Across three and a half centuries, across wildly different epistemological contexts, across institutions ranging from the Royal Society to the Victorian SPR to the United States Department of Defense, there has been a consistent refusal to simply discard anomalous reports. Someone always writes it down. Someone always, eventually, releases the documents.

This matters for a reason that is easy to miss. The standard critique of paranormal and UAP research is that it operates outside legitimate institutions, that it is the province of credulous amateurs and wishful thinkers. But the documentary record says something different. The documentary record shows that legitimate institutions — courts, universities, military commands, scientific societies — have been generating and preserving anomalous reports for centuries. The question is not whether the institutions take these things seriously. They demonstrably do. The question is what we are supposed to conclude from the fact that after three hundred and sixty-four years of institutional documentation, we still cannot say what any of it is.

One possibility, which the psychological literature takes seriously, is that human perception and cognition are sufficiently unreliable under certain conditions to generate consistent categories of misperception across time and culture. The research on paranormal belief and sensory-processing sensitivity is relevant here: pareidolia, apophenia, the tendency to impose pattern on ambiguous stimuli. These are real phenomena. They should be taken seriously as explanations.

But they do not explain everything in the record. The Pantex object triggered automated security systems before any human observer was involved. The UPS cargo flight over Alaska in July produced video footage reviewed by people who fly aircraft for a living. The PURSUE documents include radar data and sensor readings alongside eyewitness accounts. The evidentiary standards have changed since 1661, even if the institutional behavior — document it, preserve it, eventually release it — has not.

What I find genuinely strange, sitting with all of this, is not the individual cases. It is the meta-pattern. We have built, apparently without intending to, a multi-century archive of things we cannot explain. The archive keeps growing. The explanations remain partial. And the institutions that generate the archive — the ones that are supposed to, eventually, produce the explanation — keep adding to it without closing it.

Glanvill thought the Tedworth case mattered because he believed it was evidence against Sadducism, against the philosophical position that there is no spiritual reality. He was wrong about what it evidenced, probably. But he was right that the impulse to document it was the correct one. Whatever the phenomena are — misperception, unknown atmospheric physics, sensor artifacts, something we have not yet named — the archive is the thing of value. The record is what we have.

The next tranche will come. There will be more documents. The case will remain, officially, unresolved.

I think that is the story.
