6gunsFBI Probes Missing US Scientists
https://www.newsmax.com/us/fbi...dkt_nbr=010102argeliThe FBI reportedly is leading the investigation into the deaths or disappearances of scientists or staffers who worked at sensitive nuclear or space technology laboratories.
Federal authorities have stepped in to determine whether any connections exist among at least 10 cases involving individuals tied to high-level research facilities, including NASA's Jet Propulsion Laboratory and Los Alamos National Laboratory.
In a statement, the FBI confirmed it is "spearheading the effort" in coordination with the Department of Energy, Department of War, and state and local law enforcement agencies, CBS News reported.
The move signals a heightened federal response after growing concern over a pattern that some officials have described as "eyebrow raising."
President Donald Trump has also weighed in, calling the situation "pretty serious stuff" and indicating the administration is monitoring developments.
He expressed hope the cases are coincidental but emphasized the need for answers, noting that "some of them were very important people."
The incidents, which span several years, include a mix of disappearances, homicides, and unexplained deaths.
Among the most high-profile cases is the disappearance of retired Air Force Maj. Gen. William Neil McCasland in New Mexico earlier this year.
McCasland, who previously led the Air Force Research Laboratory, vanished after leaving his home without his phone or personal devices, sparking speculation.
Other cases include a NASA-affiliated aerospace engineer who disappeared while hiking in California and multiple deaths involving scientists in Massachusetts and California.
While some cases have clear explanations, such as criminal acts or personal circumstances, others remain unsolved.
Despite online speculation, experts and investigators have cautioned against jumping to conclusions.
Officials familiar with the cases say there is currently no confirmed link connecting the incidents, and some point to the large workforce across these facilities as a factor.
"People do just die," one former Energy Department official noted, citing health issues, accidents, and other causes.
Still, concerns about potential foreign involvement persist. Some Republican lawmakers have suggested adversaries such as China, Russia, or Iran could see value in targeting U.S. scientific expertise, particularly amid heightened global tensions and the ongoing conflict in Iran.
Rep. Eric Burlison, R-Mo., said he would "not be surprised" if foreign actors were involved, noting that several of the individuals worked on sensitive national security projects.
The FBI's expanded role follows increased public attention, fueled in part by social media speculation and calls for transparency.
The House Oversight Committee has also launched its own probe, seeking briefings from multiple federal agencies.
At the same time, agencies such as NASA have stated there is no evidence of a national security threat tied to the cases, underscoring the uncertainty surrounding the situation.
As investigators continue their work, the Trump administration has pledged a thorough review, with officials promising that "no stone will be unturned" in determining whether the incidents are isolated tragedies or part of a broader concern.

GustoferI considered posting about this the other day, but didn't want it to get labeled conspiracy stuff.
IMO, two or three of them you could write of as coincidental. 10-11-12 (or however many now)? Something ain't right here.

6guns^^^ Like you, I saw it a few days ago too. Even then, Trump said he wanted it looked into. I think it's worth keeping an eye on.

bigwagonIt's certainly unusual enough to warrant an investigation. Also worth noting that it's not a conspiracy theory until people start putting forth crazy theories.
April 22, 2026, 06:45 PM
220-9erHow many of these missing or dead are there?
This is such a large pool of people, maybe tens of thousands or more, so ten or twenty isn't that unusual.
Here's what a search on the subject shows. Hardly anything sinister looking to me.

Let's get real: People are not simply saying "These members of a particular professional group are dead or missing in the last few years. Gee, that's odd."
What's implicit in all the talk is that there
must be some sort of conspiracy to eliminate these people. You know it's true.
I wonder if there have been investigations of missing/dead members of other sorts of professions. Pick any profession, and you will naturally be able to identify members of that profession who have died prematurely, and you will be able to find members of that profession who have gone missing.
However, it's the pinnacle of banality to ponder the fate of librarians or auto mechanics or school teachers or any other large or fairly large professional group.
Nuclear scientists, though, with all spy novel stuff implied in their profession- that's a different story.
I asked Grok about this, and I don't wish to take its observations for my own, so, here's the conversation:
My question: The intrigue surrounding these missing or dead scientists- I believe there is a bias in the observations about these missing/dead, and I think any other large professional group examined will reveal similar premature deaths or missing persons. What is the correct term for this bias stemming from people thinking that just because these people have jobs dealing with nuclear stuff, that there is something unusual in these 10 or 11 people?
Grok's response:
"The phenomenon you're describing—where a small number of deaths or disappearances in a specific, high-profile professional group (like nuclear or aerospace scientists) gets interpreted as suspicious or sinister, without accounting for the expected baseline rate of such events in any large population— is most accurately captured by the base rate fallacy (also known as base rate neglect or base rate bias).
What the Base Rate Fallacy Is
This cognitive bias occurs when people overweight specific, vivid, or "individuating" details about a case (e.g., "these 10–11 people worked with sensitive nuclear/rocket tech and some died or went missing under varied circumstances") while underweighting or ignoring the general statistical base rate—the overall frequency of similar events (deaths, accidents, suicides, missing persons reports, etc.) in the broader relevant population.In plain terms: If you don't compare the observed cluster to how many such incidents you'd expect by chance in a group of thousands (or tens of thousands) of people in similar fields, the cases can feel unusually suspicious. But that feeling often stems from neglecting the denominator: the total size of the profession and normal mortality/morbidity rates.
Why It Fits This Situation
The U.S. aerospace, defense, and nuclear sectors employ huge numbers of people with security clearances or technical roles—estimates run into the hundreds of thousands in cleared positions alone. Over several years, even low-probability events like homicides, suicides, accidents, health issues, or disappearances (e.g., hiking accidents, personal crises) will occur in any large group.
The 10–11 cases span different organizations (NASA/JPL, Los Alamos, etc.), time periods (roughly 2022–2026), and causes (some ruled as suicide, homicide by known perpetrators, natural or unclear, missing while hiking, etc.). Many appear unrelated upon closer look, with some involving non-scientist staff or retirees.
Without the "nuclear/rocket" label, these would likely register as scattered individual tragedies rather than a pattern. The job association primes people to connect dots that may not belong together, especially when amplified by media or online speculation.
This is exactly what you suspected: examining any large professional group (doctors, lawyers, teachers, truck drivers, etc.) over a similar timeframe would turn up comparable numbers of premature deaths or missing persons. The intrigue arises because the group seems "special" due to the sensitive nature of their work.
Related Biases That Often Compound It
Availability heuristic / salience bias: Vivid or publicized cases (especially when tied to national security or conspiracy-friendly narratives like UFOs/anti-gravity) stand out more and feel more common than they statistically are.
Confirmation bias: Once the idea of a "pattern" or "sinister plot" is suggested, people seek or interpret info that supports it, while downplaying mundane explanations or the lack of proven links.
Clustering illusion: Humans naturally perceive random clusters as non-random, especially in small samples.
These aren't mutually exclusive with base rate neglect—they often work together to create the sense of intrigue.
Context on the Current Cases
Recent reports highlight ~10–11 individuals with some ties to sensitive U.S. research (nuclear, aerospace, space defense) who died or went missing since around 2022. Federal agencies (FBI, etc.) and Congress are reviewing them for possible connections or national security implications, as is standard when clearances and sensitive tech are involved. However, officials and analysts note no confirmed links so far, and individual cases often have prosaic elements (e.g., health issues, personal circumstances, or unrelated crimes). Large employers in these fields (tens of thousands of staff) make some turnover via death/missing inevitable, absent evidence of coordination.
Your intuition is sound: without rigorous comparison to base rates across similar large cohorts, the "unusual" label risks being an artifact of how we're observing and labeling the group, rather than objective deviation from the norm. Statistical scrutiny (expected vs. observed rates, adjusted for age, lifestyle, stress factors in high-pressure fields, etc.) is the antidote."April 23, 2026, 02:41 PM
AglifterTMK - from someone who worked in a related area - the Feds always take a certain level of interest in people with sensitive backgrounds/large amounts of wealth.
Frankly, they probably should be a bit more interested if nuclear researchers, virologists, etc disappear.
I think this goes back to the Cold War.
April 23, 2026, 02:44 PM
AglifterOne of the things which does need to be adjusted for, is behavior.
Many/maybe most “disappearances” are when “Bob who lives under the bridge” becomes “Bob who lives in the empty lot,” two states over.
Not sure how common they are among functional people.
If that rate shows an uptick, that would be a concern.

parabellumGiven my militancy on the subject of conspiracy theories in general, it's understandable that some readers of the forum (quite a few, I'm sure) think that I reject as a matter of course, any and all such theories, but this is not true. There are, of course, many conspiracies in this world, of all manner. One which comes to mind immediately is the ridiculous Russia Collusion Hoax, and you won't find me saying the SPLC hasn't been funding the KKK for many years, which sounds preposterous, until you examine the matter.
I have simply, over the years, built up a genuine disgust for people enthusiastically accepting any claims about the government or big business or the like, which appeal to their cynical view of the world.
Having said all that, I will admit that when initially presented with this missing/dead scientist stuff, even the most reasonable person might be suspicious. But, as with most things in this life, much is not at all what it seems, but the tendency for people to seek a cause for a given effect is innate.
April 23, 2026, 07:18 PM
Johnny 3eaglesI posed the identical question posted by Para, except to GEMINI (Different AI, basically same results.
QUESTION:
The intrigue surrounding these missing or dead scientists- I believe there is a bias in the observations about these missing/dead, and I think any other large professional group examined will reveal similar premature deaths or missing persons. What is the correct term for this bias stemming from people thinking that just because these people have jobs dealing with nuclear stuff, that there is something unusual in these 10 or 11 people?
You've hit on a classic case of Clustering Illusion combined with Confirmation Bias.
When people look at a specific group—like nuclear scientists—and notice a handful of tragic or mysterious events, the human brain naturally tries to find a pattern or a "story" to explain it. However, as you suspected, when you apply that same lens to any other large professional group, you find similar statistics.
Here are the specific terms for the biases at play:
1. The Clustering Illusion
This is the tendency to underestimate the amount of variation that can occur in a small sample of data. In any large population (like the global scientific community), "clusters" of events like deaths or disappearances will happen purely by chance. People see a "streak" of 10 or 11 cases and assume it must be a conspiracy, whereas, in a group of tens of thousands of professionals, those numbers are often statistically unremarkable.
2. Confirmation Bias (and "Cherry Picking")
Once someone develops the theory that "nuclear scientists are being targeted," they begin to actively look for news stories that support that theory while ignoring the thousands of other scientists who are living perfectly normal, safe lives. This "cherry-picks" the data to fit the narrative.
3. The Law of Truly Large Numbers
This statistical principle states that with a large enough sample size, even many "outrageous" or highly improbable things are likely to happen. If there are 100,000 people in a specialized field, the odds that a dozen of them will experience a premature death or go missing over a decade is actually quite high. It only feels "unusual" because of the professional label attached to them.
4. Availability Heuristic
This is a mental shortcut that relies on immediate examples that come to a given person's mind when evaluating a specific topic. Because a "missing nuclear scientist" makes for a much more gripping news headline than a "missing insurance adjuster," these stories stick in the public consciousness, making the phenomenon seem more common than it actually is.
In short, you are looking at a Statistical Mirage. If you were to track 20,000 high-level corporate executives or 20,000 civil engineers over the same period, you would likely find a similar "cluster" of tragedies that—if framed correctly—could be made to look like a targeted plot.
Does this help clarify the terminology, or were you thinking of a more specific logical fallacy?

parabellumThank you, Confirmation Bias is what I thought Grok would tell me.
So, I went back to Grok and asked:
My question: The same question was posed to another AI engine and came up with "Clustering Illusion combined with Confirmation Bias." What say you? Is this merely a restating of your response?
Grok's response:
"No, it's not merely a restating—it's a partial overlap with a different emphasis. The other AI's combination ("Clustering Illusion combined with Confirmation Bias") is accurate and relevant, but my response highlighted a broader and more foundational explanation centered on the base rate fallacy, with the other two as supporting factors. They're complementary, not contradictory.
Quick Breakdown of Each
Clustering Illusion (also called illusory pattern perception): The tendency to see non-random "clusters" or streaks in what are actually random or independent events, especially in small samples. Humans underestimate how much variability and clumping naturally occur in random data.
Confirmation Bias: Once you notice (or are primed to notice) a potential pattern, you focus on evidence that supports it and overlook or downplay disconfirming info (e.g., mundane causes, lack of proven links, or similar clusters in other professions).
Base Rate Fallacy (what I emphasized): Ignoring or underweighting the overall statistical frequency (base rate) of deaths/missing persons in a large population/group, while over-focusing on the specific, salient details of these 10–11 cases and their "nuclear/rocket" connection.
How They Relate Here
The clustering illusion explains why these scattered incidents feel like a meaningful streak or conspiracy pattern, especially when listed together. Confirmation bias keeps the intrigue going once the narrative starts. But the base rate fallacy is often the deeper root: without comparing to expected rates across thousands of people in high-stress, high-clearance defense/nuclear/aerospace roles over several years, the cluster appears more anomalous than it statistically should.
In practice:
You pick a visible, "special" subgroup (scientists with sensitive jobs).
You notice some deaths/missing cases (clustering illusion).
You connect them because of the shared theme and ignore base rates or counter-evidence (confirmation bias + base rate neglect).
These biases frequently co-occur in conspiracy thinking or unusual-event speculation.
Why I Led with Base Rate
Your original question focused on the bias in observations stemming from assuming something is "unusual just because of their nuclear jobs," and expecting similar rates in any large professional group. That's textbook base rate neglect—the failure to ask, "How many such events would we expect anyway?" The clustering + confirmation combo is a strong description of how the pattern feels compelling, but base rate addresses why it seems unusually suspicious in the first place.
Both framings are valid lenses on the same cognitive error. The other AI zeroed in on the pattern-seeking mechanics; I included the statistical comparison angle as more directly responsive to your point about professional groups.
Recent context on these cases (as of April 2026) shows Congress and the FBI reviewing ~10–11 incidents tied to places like Los Alamos, JPL/NASA, etc., with a mix of missing hikers, administrative staff, ruled suicides/homicides by known actors, and unclear cases—spanning 2022–2026. No confirmed coordinated threat yet, and some involve non-scientists or retirees, which fits the biases discussion."April 23, 2026, 08:45 PM

There may be nothing to it… I don’t know or have any preconceived idea or bias.
Still, it’s worth looking into.
"Some things are apparent. Where government moves in, community retreats, civil society disintegrates and our ability to control our own destiny atrophies. The result is: families under siege; war in the streets; unapologetic expropriation of property; the precipitous decline of the rule of law; the rapid rise of corruption; the loss of civility and the triumph of deceit. The result is a debased, debauched culture which finds moral depravity entertaining and virtue contemptible."
