UFOs: The Research, the Evidence

Status
Not open for further replies.
Sohdner I have neither the time nor inclination to argue this Venezuelan thing with you all over again, The case has been debated extensively and recently in this thread over the last few pages - and of those who have been most closely involved in that debate the consensus is that the letter is not a hoax. For example:
Fwiw, I do belive that the letter is genuine based on the discussions of it and the author in other places. F ex. http://genforum.genealogy.com/cowgill/messages/348.html
To whit, I read Cowgill's letter again, and I noticed something very interesting - a simply stated fact that potentially gives far more weight to them telling the truth than anything you've argued.
There are many reasons for both myself and these good people coming to those conclusions (that the letter is not a hoax) - and these reasons are outlined in the previous few pages in this thread (beginning on page 199). The best advice I can offer you at this point is to go back and follow the debate through and then draw your own conclusions.

I have read the reports. I have reviewed the evidence. In the Argentina case none of the reports, evidence, or even commentary here suggest that there is reason to dismiss the idea that it is a hoax.
You have reviewed the evidence? You give yourself away! It was Venezuela – not “Argentina”… (http://bp0.blogger.com/_-qWvml8_fAg/SGccRWGaJpI/AAAAAAAAAF8/J2QyUR-1d0E/s1600-h/SciAm2.JPG).

I'm not a "UFO Debunker". I don't even know what you mean by that…
Debunk: “ to expose or excoriate (a claim, assertion, sentiment, etc.) as being pretentious, false, or exaggerated” (http://dictionary.reference.com/browse/debunk)

…do you think I deny that people see flying objects they can't identify? I don't.
So tell me then: Do you believe there are any UFO cases that defy mundane explanation?

Do you mean I insist these things can't ever be aliens? I don't.
So tell me then:
Do you believe ET exists?
Do you believe the ETH may represent a potential explanation for some UFO sightings?

I just want to base things off of evidence where possible…
What do you make of the following case then?

The Delphos Kansas UFO Landing (11 Feb 1971)
(http://www.ufocasebook.com/Kansas.html)
(http://www.ufoevidence.org/cases/case192.htm)
The following site contains some photos of the UFO landing ring, taken 10minutes, 16 hours and 3.5 years after the event.
(http://naturalplane.blogspot.com/201...ding-ring.html)
There is also a link to a subsequent soil analysis conducted in 1999
(http://documents.theblackvault.com/d...nger/UT001.pdf).

...and if I have to suggest solutions where not enough information is available to be sure I tend towards plausible mundane explanations because if I jump right to the implausible and fantastic where do I stop?
No-one is pretending to explain UFOs in this thread …well …the UFO debunkers explain them as misidentified mundane objects and hoaxes … but I am merely pointing out that there are UFO cases that simply defy mundane explanation. One is of course free to speculate explanations, but that is not what I am about here.

Why, for example, would I say the Argentina thing was aliens at all? Why not some psychic event? Why not some cryptozoological incident?
There you go again …Argentina? Are we even talking about the same case? I could have sworn we were discussing the Venezuelan case. What makes you think that some sort of creature was involved? Perhaps you have another case in mind altogether – one that has not been mentioned in this thread?
 
I stated:
”While overall, 21.5% of all reports studied were classified as Unknown, it is interesting to note that of the 2199 reports examined, 213 (9.7%) were classified as having an “Excellent” reliability - and of those 71 (33.3%) were classified as “Unknown” (p.24).”
I then said that 77/2199 is around 3%, not 20%. I don't understand why you claim that (at least) about 20% of all UFO cases remain unexplained in mundane terms. A big portion of those are of lower quality.
That would be 71 of the 213 reports whose reliability was rated as “Excellent” is 33.3’%. When you then include all reports (to include the “lower quality” Good, Poor and Doubtful reports) then that figure drops to 21.5% (hence “at least 20%”).
 
and of those who have been most closely involved in that debate the consensus is that the letter is not a hoax. For example:
Of course, it can still be a hoax but I'm prepared to believe that Warner actually wrote this.
things that Cowgill could have first hand knowledge of, assuming that he is telling the truth.

Yes, I see that both people are willing to entertain that the letter was written by the person it claims to be written by. Even if they are correct - and there is no proof of this - it could still be that Cowgill was making the whole thing up.

It was Venezuela – not “Argentina”

Indeed! Slip of the tongue, so to speak.

So tell me then: Do you believe there are any UFO cases that defy mundane explanation?

I don't know what the word "mundane" really adds to that sentence. I would say that some Unidentified Flying Objects remain Unidentified. Of the ones that are positively identified, all have been mundane objects but that's to be expected - if something was not mundane it would of course be harder to identify because we would be less familiar with it. That being said, something being hard to identify does not mean that it is not mundane.


Do you believe ET exists?

I think it seems logical to say that there are life forms on other planets. It further seems logical to suppose that some life that is fairly intelligent would have arisen elsewhere at some point, although that wouldn't mean that they did so near to us or at the same time, or that there has been any interaction.

Do you believe the ETH may represent a potential explanation for some UFO sightings?

In theory, yes. That being said, I've never seen any evidence that has been compelling.

What do you make of the following case then?

Not until you can tell me how you can rule out a hoax as the explanation for the Venezuela case.

No-one is pretending to explain UFOs in this thread
I stated that I would present the evidence, not only for UFOs, but also for “aliens”. The following set of links provides just that.

It seems like, from the OP, you are saying that the explanation for these UFOs is "aliens".

What makes you think that some sort of creature was involved?

What makes you think that it wasn't? Why go right to UFOs? In fact, nothing "flying" was even mentioned in the letter, nor was an object as such. This is, at best, an unexplaned incident. Saying that UFOs were involved makes a number of assumptions. What if I suggest that instead this was a cryptozoological incident? What if I say it was a psychic backlash? What if I say that it was magic? What if I say that it was some sort of natural but rare event caused by some exotic meteorite? What if I say that it was due to time travel? What if it was aliens of some sort, but they teleported in rather than using a spacecraft? None of these are UFOs, and most don't involve aliens.

Even if the letter is an accurate account - and I am by no means prepared to say that - we still shouldn't even be calling it a UFO case.
 
I stated:

Sorry, typo.

Your claim was that at least 20% of ALL reports could not be plausibly attributed to eyewitness error or inexplicable in mundane terms. You can't know that if the reports are not of high quality and a big portion of ALL reports are such.

71 out of ALL 2199 reports is 3%, not at least 20%.
 
In this respect everything that is not “Unknown” is obviously an eyewitness “error” of some sort. Given that the “Unknown” category comprised (more than) 20% of the reports (and of those, the most reliable reports returned a value of 33% unknown) then it is reasonable to state that (at least) 20% of the reports could not be plausibly attributed to eyewitness error. Please, tell me what it is you don’t understand about that (…but before you do, please read the report – the first 12 or so pages will suffice if you don’t want to read the whole thing…).

No. Just because the researchers don't know what an object is doesn't mean that there was no eyewitness error. That's something that you are projecting on to it, not something the researchers have demonstrated. If they have, then you can quote where they say that themselves.

Now, are you going to back up your claim with actual evidence, or are you going to admit that it's wrong?

To be fair, I don't think this is really a helpful argument. Yes, UFO technically stands for "unidentified flying object", but that's not how it's actually used. In general, it simply means "unidentified thingy that appeared that it might have been flying, or at least kind of up in the sky somewhere". Planets, stars, reflections in windows, video artefacts, oil wells, and many other non-flying and non-object things have all been identified as the cause of UFOs at one time or another. It's doesn't help the argument on either side to say that they weren't actually UFOs at all, since then we'd just have to invent a new, not generally understood, word to describe exactly the same phenomenon.

Agreed - but in the case I was referring to they just described a light, sound, and smoke (and then various injuries to the people and plants). There wasn't an object, flying or otherwise, described.

It's doesn't help the argument on either side to say that they weren't actually UFOs at all, since then we'd just have to invent a new, not generally understood, word to describe exactly the same phenomenon.

Just to be clear, I agree here too. It's a UFO as long as it was unidentified, flying, and an object to the observer at the time of observation. It may later be identified, or determined to have not been flying, or even to not be an object at all - but whatever happens later doesn't change that it was a UFO at the time.

A bright light, a sound, and some smoke? Not a UFO in my book because there was no F or O described or observed.
 
Yes, I see that both people are willing to entertain that the letter was written by the person it claims to be written by. Even if they are correct - and there is no proof of this - it could still be that Cowgill was making the whole thing up.
Based on the evidence the letter is not a hoax and Cowgill is describing a real incident to the best of his knowledge. There is no evidence to suggest that the event did not occur substantially as told in that letter, while there is evidence to suggest veracity.

The problem we then have is in how to explain the case in mundane terms. On the face of it some form of radiation poisoning is the obvious answer. But radiation poisoning in 1886 in rural Venezuela? Alternatives have been proposed (from normal burns to heavy metal poisoning to lying to cover up some nefarious activity or other) but given the evidence none of those hypotheses can be plausibly supported. Even the radiation poisoning hypothesis has its problems. Yet there is nothing to suggest that the events did not occur substantially as related. It is a true mystery. Nothing quite fits. It simply defies mundane explanation.

You asked:
” Why not some cryptozoological incident?”
And I replied (not sure you were actually referring to this case – because you repeatedly stated “Argentina”… even though you claimed to have reviewed all the evidence in the case including the posts in this thread…):
” What makes you think that some sort of creature was involved? Perhaps you have another case in mind altogether – one that has not been mentioned in this thread?”

What makes you think that it wasn't? Why go right to UFOs? In fact, nothing "flying" was even mentioned in the letter, nor was an object as such. This is, at best, an unexplaned incident. Saying that UFOs were involved makes a number of assumptions.
Just to be clear, I agree here too. It's a UFO as long as it was unidentified, flying, and an object to the observer at the time of observation.

A bright light, a sound, and some smoke? Not a UFO in my book because there was no F or O described or observed.
Actually, if you had reviewed the posts in this thread you would see that I have not called it a “UFO”. Rather I contended that it has many of the elements of a UFO case and thus closely resembles a UFO case, yet nowhere in the letter is a UFO mentioned and in fact Cowgill presented it as a “curious” meteorological phenomenon – and Sci Am published it as such. One of the reasons I presented the case was to demonstrate that such reports were occurring long before UFO reporting became (according to the UFO debunkers) driven by popular culture.

I must also note that it is a typical UFO debunker response to a definition of UFOs that it is a UFO only if it is unidentified "to the observer at the time of the observation". The rationale for making this a definitional requirement is of course to preclude subsequent research and to provide a more secure foundation for the "eyewitness error" objection to UFO sightings. This of course reflects a belief that ALL UFO sightings are merely eyewitness misidentifications and works fine when subsequent research provides a mundane explanation - but they run into trouble when subsequent research maintains the status of UFO. But then of course thay simply say that there is not enough information to make a mundane determination. Further trouble arises when there is enough information to conclude that the characteristics of the sighting simply defy mundane explanation. Then they twist and turn and generally avoid the question and often simply refuse to discuss the case - or cry "Hoax!" When it is then shown that a hoax is not plausible, then they have nowhere to go except to retreat into the infinite universe and mere possibility - throwing out plausibility, Occam's razor and the weight of evidence all in one breath (while adding an accusation that the UFO proponant does that very thing - fervently hoping that will put the proponent immediately on the defensive and distract argument away from the case itself).

What if I suggest that instead this was a cryptozoological incident? What if I say it was a psychic backlash? What if I say that it was magic? What if I say that it was some sort of natural but rare event caused by some exotic meteorite? What if I say that it was due to time travel? What if it was aliens of some sort, but they teleported in rather than using a spacecraft? None of these are UFOs, and most don't involve aliens.
You are free to speculate any explanation for the event you like. However, whatever explanation you come up should be plausible and should accord with the evidence we have - and the principle underlying Occam’s razor should also apply.

Cryptozoological? No creatures were mentioned and to imagine one as the cause would require too many unfounded assumptions – compared with for example the author’s and Sci Am’s assumption that it was some sort of meteorological phenomenon. That is we would find it difficult to relate a plausible story where an “unknown” creature causes a brilliant light that awakens the victims and “burns” them – we can however imagine some sort of “plasma ball” as a causal meteorological phenomenon – except for the fact that no such phenomenon has ever been recorded… however, the UFO thing comes back into it because there have been other cases where such phenomena have been recorded where a UFO has been noted as the cause and that also resulted in the victims having the same (or very similar) symptomatology (The Cash/Landrum incident for example - http://www.nicap.org/cashlan.htm).

Even if the letter is an accurate account - and I am by no means prepared to say that - we still shouldn't even be calling it a UFO case.
Perhaps, perhaps not, it’s a value judgement after all – all I am saying is that it has all the elements of a UFO case without ever overtly or even by implication mentioning UFOs - and I presume by “UFO” you actually mean an ET vehicle of some sort – but as Cuddles points out, UFO simply means “unidentified”. That is in response to your “explanations”:

To be fair, I don't think this is really a helpful argument. Yes, UFO technically stands for "unidentified flying object", but that's not how it's actually used. In general, it simply means "unidentified thingy that appeared that it might have been flying, or at least kind of up in the sky somewhere". Planets, stars, reflections in windows, video artefacts, oil wells, and many other non-flying and non-object things have all been identified as the cause of UFOs at one time or another. It's doesn't help the argument on either side to say that they weren't actually UFOs at all, since then we'd just have to invent a new, not generally understood, word to describe exactly the same phenomenon.
The only thing I would add to that is that while many UFO sightings can be plausibly explained in mundane terms as the things Cuddles mentions, a significant proportion simply cannot. Which of course brings us back to the research and precisely what proportion of sightings cannot be plausibly explained in mundane terms.

Your claim was that at least 20% of ALL reports could not be plausibly attributed to eyewitness error or inexplicable in mundane terms. You can't know that if the reports are not of high quality and a big portion of ALL reports are such.

71 out of ALL 2199 reports is 3%, not at least 20%.
If you are ruling out reports that are of “lower” reliability as unable to be assessed as “unknown”, then they also cannot be assessed as “known” - either the information is present and reliable enough to make an assessment of the report - or it is not. That is, you cannot say the reports were reliable enough to conclude a mundane explanation, yet at the same time not reliable enough to conclude “unknown”.

Seventy one of the 213 reports that were classified as “excellent” reliability were classified as “unknown”. That’s 33% unknown.

No. Just because the researchers don't know what an object is doesn't mean that there was no eyewitness error. That's something that you are projecting on to it, not something the researchers have demonstrated. If they have, then you can quote where they say that themselves.
To counter that the researchers (including psychologists) assessed the reports for reliability:
To clarify:

To categorise a report’s reliability, two scores were assigned - one each for the observer and the report drawn from the following scale:
”X
Y
0 Complete
1 Quite
2 Fair
3 Doubtful
4 Poor
5 Not
6
7
8
9 Cannot be judged” (p.308) (http://www.ufocasebook.com/pdf/specialreport14.pdf)​
The considerations taken into account when creating those two reliability scores were:
”Ratings were assigned on the basis of the following factors of information, 'considered in relation to one another:

(1) The experience of the observer, deduced from his occupation, age, and training;

(2) The consistency among the separate portions of the description of the sighting;

(3) The general quality and completeness of the report;

(4) Consideration of the observer' s fact-reporting ability and attitude, as disclosed by his manner of describing the sighting.” (p.11) (http://www.ufocasebook.com/pdf/specialreport14.pdf)​
The overall report reliability categorisation was then assigned in consideration of both the observer and report reliability scores as follows:
”Excellent (Observer 0 or 1 and Report 0 or l)
Good (Observer 0 or 1, Report 2, 3, or 4; Observer 2, 3, or 4, Report 0 or l; Observer
2, Report 2)
Doubtful (Observer 0 or 1, Report 5 or 9; Observer 2, Report 3, 4, 5, or 9; Observer
3 or 4, Report 2, 3, 4, 5, or 9; Observer 5 or 9, Report 0, .1, 2, 3, or 4)
Poor (Observer 5, 9, or Y, Report 5, 9, or Y)” (p.308) (http://www.ufocasebook.com/pdf/specialreport14.pdf)​

I assume you would agree that the more reliable the report, the less likely “eyewitness error” is involved. The interesting statistic then to note in all that is that the more reliable the report, the greater the percentage of unknowns there was!

I hope you realise what that actually means. The more “eyewitness error” is removed from the equation, the less likely the sighting can be explained in mundane terms! Or: The more eyewitness error assumed, the more likely a mundane explanation will be found. The data is then telling us something important. Assume eyewitness error and mundane explanations are likely to be found. Take eyewitness error out of the equation and mundane explanations are less likely to be found.

I think you also may have a somewhat confused concept of what “eyewitness error” actually means? Have a careful read through the “reliability” parameters the scientists assessed (above). You will find (among other things) that observer experience, training and fact-reporting ability and report consistency, completeness and quality were assessed. These are generally things that mitigate eyewitness error.

Of course the old UFO debunker standby is “eyewitness error”, but here is a research report that accounts for such error and finds that the less error, the greater the proportion of unknowns. That is not my “projection” – those are the research findings.

Returning to some questions I asked SOdhner:
” So tell me then: Do you believe there are any UFO cases that defy mundane explanation?”
I don't know what the word "mundane" really adds to that sentence. I would say that some Unidentified Flying Objects remain Unidentified. Of the ones that are positively identified, all have been mundane objects but that's to be expected - if something was not mundane it would of course be harder to identify because we would be less familiar with it. That being said, something being hard to identify does not mean that it is not mundane.
No, I asked if you believed if there were any UFO cases that defied mundane explanation. Clearly, based on your answer you believe that ALL UFO cases can be explained in mundane terms – just that for some we simply don’t have the information to determine that mundane explanation as yet.

If “something was not mundane” we could still describe its characteristics (size, shape, manoeuvrability, other distinctive features, etc) and then make a determination of whether those characteristics fitted with any known mundane cause. Often in UFO cases we have a great deal of descriptive characteristic detail and yet are still unable to fit a plausible mundane explanation to it. That is what I mean by a sighting defying mundane explanation. We have the descriptive information, but that information simply does not fit with any plausible mundane cause. That’s why I asked:
What do you make of the following case then?

The Delphos Kansas UFO Landing (11 Feb 1971)
(http://www.ufocasebook.com/Kansas.html)
(http://www.ufoevidence.org/cases/case192.htm)
The following site contains some photos of the UFO landing ring, taken 10minutes, 16 hours and 3.5 years after the event.

There is also a link to a subsequent soil analysis conducted in 1999
(http://documents.theblackvault.com/d...nger/UT001.pdf).
…and of course you refuse to answer:

Not until you can tell me how you can rule out a hoax as the explanation for the Venezuela case.
I have stated my case. The evidence is in. It is not plausible to propose a hoax. I can lead the horse to water... but obviously you have your own opinion - and it seems not even the evidence is going to change that now.

I also asked:
” Do you believe ET exists?”
I think it seems logical to say that there are life forms on other planets. It further seems logical to suppose that some life that is fairly intelligent would have arisen elsewhere at some point, although that wouldn't mean that they did so near to us or at the same time, or that there has been any interaction.
It also does not mean that there has not been interaction.

”Do you believe the ETH may represent a potential explanation for some UFO sightings?”
In theory, yes. That being said, I've never seen any evidence that has been compelling.
Is that because you refuse to explore the evidence? I only ask because you seem to be taking that line in the Delphos case (above). Not that that case represents evidence for ETs, just noting your ostensible refusal to examine actual evidence.

It seems like, from the OP, you are saying that the explanation for these UFOs is "aliens".
You have simply failed to understand my OP then.
I must make one caveat on my meaning of “alien”. By “alien” I DO NOT mean “Extraterrestrial”. The term as I use it simply means something outside our common understanding of reality. “They” could be from “out there”, they could be from “precisely here”, they could be extra- or intra-dimensional, they could be, well, anything at all…we just do not know and without a concerted research effort, perhaps we will never truly “know”.
 
For the witnesses' extraordinary claims for what they saw, the witnesses were mistaken or hoaxing. I didn't see where you had eliminated those two. I see where you dismissed hoaxing out of hand and didn't address being mistaken at all.

For the fairy ring on the ground (what you're referring to as a UFO landing ring due to your assumptions about "aliens") it is a known fungus.

As you don't seem to be paying particularly close attention to my posts, I'll ask it a different way: Who is answering your 20 questions? The answer seems to be "Rramjet".

Since you haven't addressed this, Rramjet, I will assume that you concede you erred (again) in applying your version of a process of elimination to the Delphos case.

Are there any cases where you can show that you have correctly used a process of elimination?
 
Based on the evidence the letter is not a hoax and Cowgill is describing a real incident to the best of his knowledge.

I haven't seen any evidence that points to that. At all. And, interestingly, you refuse to link to it.

On the face of it some form of radiation poisoning is the obvious answer.

It has been pointed out to you repeatedly that the symptoms are not consistent with radiation poisoning. Some of the individual symptoms are, but not in a consistent way - and others don't align with that theory at all. Why are you so committed to the idea that it was radiation when that doesn't match the account?

I must also note that it is a typical UFO debunker response to a definition of UFOs that it is a UFO only if it is unidentified "to the observer at the time of the observation". The rationale for making this a definitional requirement is of course to preclude subsequent research and to provide a more secure foundation for the "eyewitness error" objection to UFO sightings.

You might want to avoid telling me what my own rationale is for saying things, as you have a poor track record. If I see something and identify it as a 747, and you see it and are unable to identify it, then it is a UFO to you and not to me. If I see something and can't identify it and you see it and recognize it as a reptiloid spacecraft, then it is unidentified to me and identified to you. If I see something flying and can't identify it but then later, examining pictures online, I determine what it was... then it was a UFO when I saw it but now isn't anymore. That's the nature of using "unidentified" in the description of something - if it is identified at some point or to some people the label may not apply outside of certain people or certain times.

I'll also say that I acknowledge that this goes both ways - If I see something I identify it as a 747 but then later realize that it had the wrong wing configuration then it turns into a UFO. Your assumption that I am some sort of "UFO Debunker" out to use sneaky phrases to quash investigations comes off as paranoid.

However, whatever explanation you come up should be plausible and should accord with the evidence we have - and the principle underlying Occam’s razor should also apply.

Okay. My theory is that the letter is a hoax. We know it's possible - anyone can write a letter, anyone can make up a story about a light and some strange injuries. It also doesn't assume anything not in evidence - no monsters, no magic, no otherworldly craft or time travelers. That simplicity means it passes Occam's Razor with flying colors.

This is now my null hypothesis. The letter is not factually accurate.

I will be totally willing to revise this, of course, if a better and more plausible theory comes up. So far it seems that you are suggesting that a unidentified flying object was just outside and somehow caused these injuries. This isn't really a useful theory, because it assumes some things that aren't in evidence (something flying was outside, which had the ability to cause these injuries) while not actually explaining anything at all (what was the flying thing? How did it cause those injuries?).

there have been other cases where such phenomena have been recorded where a UFO has been noted as the cause and that also resulted in the victims having the same (or very similar) symptomatology (The Cash/Landrum incident for example - http://www.nicap.org/cashlan.htm).

I disagree that the symptoms are "very" similar. There are some similarities, and also many differences. Without knowing what actually happened in either case we simply don't have any grounds to suggest they were caused by the same thing.

I presume by “UFO” you actually mean an ET vehicle of some sort – but as Cuddles points out, UFO simply means “unidentified”.

No, I don't mean an ET vehicle. I mean an unidentified flying object. This was an unidentified incident, with no object described and no flying suggested. The theory stated in the letter refers to a meteorological incident, which wouldn't necessarily involve an "object" in the traditional sense at all. The "U" is the only part we have here.

No, I asked if you believed if there were any UFO cases that defied mundane explanation. Clearly, based on your answer you believe that ALL UFO cases can be explained in mundane terms – just that for some we simply don’t have the information to determine that mundane explanation as yet.

That's the third time you have put words into my mouth in this post, and the third time you've been wrong. It's just that I don't see the point in saying that they "defy mundane explanation". I don't go around saying that things "defy non-mundane explanations" either. If we don't have an explanation for something, then it has so far defied explanation.

To be fair, in reality we have to look for some level of plausibility. You seem to agree with this, as you've assessed things as being plausible or not many times in this thread. Nothing ever defies non-plausible explanations, because if we aren't worrying about being plausible the Flying Spaghetti Monster might have done it.

Plausibility, however, has some subjectivity to it. You already believe we are being visited by aliens of some sort or another, and so the idea that it is "aliens" requires less supporting evidence for you than it would for me. It's not that I'm a "UFO Debunker", it's that after reading many cases over the years and listening to the logic and evidence for alien visitation I remain unconvinced. Once I am convinced in one case it will gain some degree of plausibility in the others, although there's still a standard of evidence before I allow something to go from "I don't know" to "aliens".

Saying it defies mundane explanations isn't helpful, any more than saying it defies non-mundane explanations would be. You ruled out a cryptozoological incident - okay, does that mean that it defies non-mundane explanations? Likewise, we can rule out the 747 but that doesn't mean that we have eliminated all mundane explanations.

It's simpler to either suggest an explanation and defend it, or say it has thus far defied explanation. The word "mundane" doesn't add to it.

It is not plausible to propose a hoax.

Well, you refuse to explain why or link to a post where it is explained. I, meanwhile, have given specific reasons that it IS plausible to suggest a hoax. In addition to that, you have no better explanation. The closest you have come is to imply that it is the same (also unidentified) craft as in the Cash-Landrum case, despite significant differences between the symptoms of the witnesses and no description of a craft at all in this case. You have also suggested radiation was involved, despite being shown several times that the specific symptoms don't align with any specific type and dosage of radiation.

Do you have an actual theory to put forth, or are you just saying "I have no idea what it was, but I can't think of anything mundane"?

Is that because you refuse to explore the evidence? I only ask because you seem to be taking that line in the Delphos case (above).

Not so. As I said several times before, I have read all the links (and then some) that you provided for that case. It's not that I have any problem with exploring the evidence, it's that I don't choose to discuss it with you when you haven't addressed my points on the previous case yet. If you will simply respond to my case for the letter being possible to explain as a hoax we can move on to the next one and discuss it.

So far you have linked to a few irrelevant posts, and then said that more relevant ones are out there somewhere but you can't be bothered to link them. By now you've put far more energy into avoiding my request than it would have taken to just link to this supposed proof that it can't be a hoax.

You have simply failed to understand my OP then.

How so? I see that you quoted yourself giving a special definition for "aliens" but that's why I had put the quotes around it. You are suggesting that "aliens" are the explanation for these cases, otherwise bringing them up in this thread would make no sense and go against your stated goal in the OP.
 
For the witnesses' extraordinary claims for what they saw, the witnesses were mistaken or hoaxing. I didn't see where you had eliminated those two. I see where you dismissed hoaxing out of hand and didn't address being mistaken at all.

For the fairy ring on the ground (what you're referring to as a UFO landing ring due to your assumptions about "aliens") it is a known fungus.

As you don't seem to be paying particularly close attention to my posts, I'll ask it a different way: Who is answering your 20 questions? The answer seems to be "Rramjet".
Since you haven't addressed this, Rramjet, I will assume that you concede you erred (again) in applying your version of a process of elimination to the Delphos case.
Considering I have addressed it, I find it perplexing that you persist in asking the same questions over and over while stating that I have not answered it, as if you believe that merely stating that I have not answered the question will somehow magically confer veracity on that statement, thereby allowing you to repeat the question. Here is my previous answer:

For Delphos: What mundane explanations have you eliminated and how did you eliminate them? This time, be specific. What 20 questions did you ask, who did you ask them of, and what were the answers?

I have a mundane explanation and I'd like to see where you went wrong in your version of a process of elimination.
As you seem to be paying particularly close attention to my posts, I am then at a loss to explain how you could have missed my introduction to the Delphos UFO landing case (on this very page):
In the interests of injecting some new material into the debate, lets; try a little process of elimination on this case:

The Delphos Kansas UFO Landing (11 Feb 1971)
(http://www.ufocasebook.com/Kansas.html)
(http://www.ufoevidence.org/cases/case192.htm)

Did it have wings? Obviously not an aeroplane then. What about its size? Six to eight feet in diameter! Obviously not a helicopter, hot air balloon, dirigible or blimp… and what about manoeuvrability? Can’t conclude much from that …small military experimental hovercraft perhaps? But then why would this guy (http://www.dailymail.co.uk/sciencetech/article-447317/The-flying-saucer-snapped-US-army.html) win a contract with the US government in 2007 if they already had them in 1971?! (and why the excitement over this little number - http://news.ninemsn.com.au/glanceview/144164/new-firefighting-tool-could-save-lives.glance ?) And what about the brightness of the light… Okay, so what about a hoax? But then you have to account for the physical trace evidence – the “ring” on the ground, the glowing substance… the ring was ”vegetal in nature and belonged to an organism of the order of Actinomycetales…” ” Actinomycetaceae is a family of bacteria in the order that contains the medically important genus Actinomyces.” (http://zipcodezoo.com/Key/Bacteria/Actinomycetaceae_Family.asp) and “morphologically Actinomyces colonies form fungus-like branched networks of hyphae (…) Actinomyces are known for causing disease in humans, and for the important role they play in soil ecology” (http://zipcodezoo.com/Key/Bacteria/Actinomyces_Genus.asp#cite_note-Holt_1994-0). So rings? And what of the nature of that ring? ” The circle was still very distinct and plain to see. the soil was dried and crusted. The circle or ring was approximately 8 feet across, the center of the ring and the outside area were still muddy from recent rains. The area of the ring that was dried was about a foot across and was very light in color. (…) Further experimentation showed the ground under the ring to be dry to a depth of one foot. The ring itself was composed of a whitish substance, which was sent to a laboratory for analysis.” (http://www.ufocasebook.com/Kansas.html), yet ” One of those ingredients turns out to be bacteria with a pretty unpronounceable name - actinomycetes. These bacteria flourish in damp, warm soils. (…) Actinomycetes bacteria mean healthy soil and healthy people. Researchers have isolated several antibiotics from ordinary garden dirt. Something to think about the next time you take a stroll after a rainstorm.” (http://www.npr.org/templates/story/story.php?storyId=12716163). This ring was hardly “healthy soil” and Actinomycetes have never been noted to grow into a ring of dry, hydrophilic soil such as was noted. So very strange indeed.

All this tends to rule our plausible mundane explanations as a cause. Perhaps though I have missed something? If so, I have no doubt someone will be able to inform me…
Not long after that post I added the following information about the case:
Here is some further evidence and analysis concerning the The Delphos Kansas UFO Landing (11 Feb 1971) that we have been discussing recently.

The following site contains some photos of the UFO landing ring, taken 10minutes, 16 hours and 3.5 years after the event.

There is also a link to a subsequent soil analysis conducted in 1999
(http://documents.theblackvault.com/documents/Budinger/UT001.pdf).

Interestingly there is also a case which echoes the Delphos UFO landing;
The Port Coquitlam, Vancouver Landing (16 Aug 1974)
(http://www.think-aboutit.com/thinke...les/2049-three-small-boys-witness-ufo-landing).


Your mundane explanation for the Delphos UFO Landing case is then..?


Are there any cases where you can show that you have correctly used a process of elimination?

There are many such cases. The following is a list of the cases where I have done that in this thread (Note: they are listed in date order – not the order they were presented in this thread)

There are of course many more cases that have not been presented in this thread where I could use the process of elimination to rule out mundane explanation – but perhaps we should stick with the Delphos one for the moment?
 
To counter that the researchers (including psychologists) assessed the reports for reliability:


I assume you would agree that the more reliable the report, the less likely “eyewitness error” is involved. The interesting statistic then to note in all that is that the more reliable the report, the greater the percentage of unknowns there was!

I hope you realise what that actually means. The more “eyewitness error” is removed from the equation, the less likely the sighting can be explained in mundane terms! Or: The more eyewitness error assumed, the more likely a mundane explanation will be found. The data is then telling us something important. Assume eyewitness error and mundane explanations are likely to be found. Take eyewitness error out of the equation and mundane explanations are less likely to be found.

I think you also may have a somewhat confused concept of what “eyewitness error” actually means? Have a careful read through the “reliability” parameters the scientists assessed (above). You will find (among other things) that observer experience, training and fact-reporting ability and report consistency, completeness and quality were assessed. These are generally things that mitigate eyewitness error.

Of course the old UFO debunker standby is “eyewitness error”, but here is a research report that accounts for such error and finds that the less error, the greater the proportion of unknowns. That is not my “projection” – those are the research findings.

This still does not back up your original claim that "research also shows us that there is a core of around 20% of cases where the information is reliable enough that eyewitness error is not a plausible explanation". Are you going to provide evidence which does back this statement up, or are you going to retract it?
 
Considering I have addressed it, I find it perplexing that you persist in asking the same questions over and over while stating that I have not answered it, as if you believe that merely stating that I have not answered the question will somehow magically confer veracity on that statement, thereby allowing you to repeat the question. Here is my previous answer:
To nobody's surprise whatsoever, you failed to respond to what I said. You asked what I thought of the Delphos case and I told you. The witnesses were mistaken or hoaxing and the fairy ring is a known fungus.

Mundane explanations not eliminated by your version of a process of elimination. Now what do you have?

There are many such cases. The following is a list of the cases where I have done that in this thread (Note: they are listed in date order – not the order they were presented in this thread)

Curious Phenomenon in Venezuela (17 Nov 1886)
(http://bp0.blogger.com/_-qWvml8_fAg/SGccRWGaJpI/AAAAAAAAAF8/J2QyUR-1d0E/s1600-h/SciAm2.JPG)
Hoaxed letter. Your process failed.

Mass hysteria. Your process failed.

Blimp. Your process failed.

Unknown

Hoax, mistaken identify. Your process failed.

Hoax. Mistaken identity. Your process failed.

Why do you cite the very case we're currently discussing where I've shown your process to be in error? Hoax or mistaken, fairy ring of known fungus. I think that's enough to show your will to believe colors your perception.

There are of course many more cases that have not been presented in this thread where I could use the process of elimination to rule out mundane explanation – but perhaps we should stick with the Delphos one for the moment?
I was. You didn't respond to my mundane explanations. Delphos is explained by hoaxing or mistaken identity and a fairy ring of a known fungus. Are you going to respond to that or not?

You may also wish to answer my question Who is answering your 20 questions, Rramjet? It seems that the answer is Rramjet. Perhaps that's where your version of a process of elimination fails.
 
This still does not back up your original claim that "research also shows us that there is a core of around 20% of cases where the information is reliable enough that eyewitness error is not a plausible explanation". Are you going to provide evidence which does back this statement up, or are you going to retract it?
I would ask you then to carefully read through the following post. I will make a couple of observations about it in relation to you point immediately after.
I stated that:
” I claimed that about 20% of all UFO cases remain unexplained in mundane terms”

Regarding the Battelle Study (http://www.ufocasebook.com/pdf/specialreport14.pdf):
”In the coding system, the choices provided for final identifications were based on ATIC s previous experience in analysis of the data. They had found that the majority of sightings could be classified as misinterpretations of common objects or natural phenomena. Accordingly, categories for objects most frequently present in the air were provided. Balloons, aircraft, astronomical bodies (such as meteors), birds, and clouds or dust were recognized as major categories. The less frequent, but common objects, such as kites, fireworks, flares, rockets, contrails, and meteorological phenomena like small tornadoes, were collected into a category called OTHER. A separate category for the uncommon natural phenomena associated with light reflections or refractions, such as mirages, sun dogs, inversion-layer images, and distortions caused by airborne ice, was established with the title of LIGHT PHENOMENON. Categories for INSUFFICIENT INFORMATION, PSYCHOLOGICAL MANIFESTATIONS, and UNKNOWN were provided for the sightings that could not be fitted into the preceding identifications.” (pp.11-12)​
The categorisation of UNKNOWN was as follows:
This designation in the identification code was assigned to those reports of sightings wherein the description of the object and its maneuvers could not be fitted to the pattern of any known object or phenomenon.” (p.12)​
I also stated that:
”While overall, 21.5% of all reports studied were classified as Unknown, it is interesting to note that of the 2199 reports examined, 213 (9.7%) were classified as having an “Excellent” reliability - and of those 71 (33.3%) were classified as “Unknown” (p.24).”

I therefore believe any fair reading of the above information (drawn and quoted as it was directly from the study) would enable the conclusion that ”…about 20% of all UFO cases remain unexplained in mundane terms”

Indeed, as I later pointed out, that conclusion of “20%” actually understates the true figure (but I find it prudent to be quite conservative when quoting research findings).

Of the “Excellent” reliability cases, a full 33.3% of them were classified as “UNKNOWN” (p.24) That means that for 33% of those cases (as I stated) "the information is reliable enough that eyewitness error is not a plausible explanation".

It is also notable that as the reliability of the cases decreased (from “Excellent” through “Good” and “Doubtful” to “Poor”), the proportion of “mundane explanation” cases rises until, for the lowest reliability cases (“Poor”), only 16.6% of cases were classified as “UNKNOWN”. This is an extremely interesting and significant finding and means that the more reliable the observer the greater the likelihood that a conclusion of “UNKNOWN” would result.

Dr. Allan J. Hynek (who for 20 years was the scientific consultant to the Blue Book project – from which the Battelle Study drew its data) also noted:
”The Battelle study further differentiated between military observers and civilians and found nearly 38 percent of the “Excellent” reports turned in by military observers were “Unknowns” while only 21 percent of the military reports rated “Poor” were “Unknowns”. The Hynek UFO Report (1978) Sphere Books Ltd. London. p.277)​
This means of course that military observers are actually more reliable than civilian observers. A point that the UFO debunkers try to hammer home every time a military UFO case is presented is that pilots etc are just as prone to observational error as civilian observers (perhaps more so as they have less reference points in the air), however, the research indicates that quite the opposite is the case: military observers are demonstrably more reliable than civilian observers!

Hynek also noted in reference to the Condon Report that ”Condon and others had indeed indicated that the unexplained sightings came invariably from poor observers” (p.276), yet the Battelle study had been published and available to Condon - and the Battelle study shows Condon to be incorrect in his conclusions here - the more reliable the observation, the greater the likelihood of a conclusion of "Unknown".

Now if you claim eyewitness error then you are of course meaning that the observer is a poor observer (because they make mistakes in their observations). However the Battelle study showed that the more reliable the observer (the better they are at observation) then the more likely it was that their report could not be explained in mundane terms. Now given that for the most reliable observers (military observers) thirty eight percent (38%!) of their reports could not explained in mundane terms – then my claim that there was a core of “around 20%” where eyewitness error is not a plausible explanation is actually (by any measure) a very conservative statement.

The UFO debunkers have claimed for a very long time that there is only a very small and insignificant percentage of UFO reports (perhaps 3–5%) where mundane explanations cannot be found - and it must be stated that many UFO proponents have simply swallowed the unfounded assertion hook, line and sinker - without any critical assessment as to its veracity. I am merely pointing out that the research and the evidence shows the assertion to be false. On a conservative estimate the unexplained figure is more like 20% and that figure rises substantially when the observer (and their report) is more reliable.

These are findings based on research and evidence – not unfounded assertion and speculation. The title of this thread is UFOs: The Research, The Evidence and that is precisely what I am presenting here.
 
Rramjet, you keep posting the same thing, despite the fact that it does not back up the claim that you originally made. That claim was that "research also shows us that there is a core of around 20% of cases where the information is reliable enough that eyewitness error is not a plausible explanation". You must know that the evidence you have presented again and again doesn't back that claim up because in the post that you asked me to re-read "carefully" you present it as evidence backing up the claim that ”about 20% of all UFO cases remain unexplained in mundane terms”. This is not the claim you made. This is an entirely different claim.

To reiterate, the claim you made was that "research also shows us that there is a core of around 20% of cases where the information is reliable enough that eyewitness error is not a plausible explanation". Now, are you going to provide some evidence to back this claim up, or are you going to retract it?
 
Rramjet said:
I therefore believe any fair reading of the above information (drawn and quoted as it was directly from the study) would enable the conclusion that ”…about 20% of all UFO cases remain unexplained in mundane terms”
And the overwhelming majority of those remain unexplained because the reports are not reliable. What's your point?

Maybe you should focus on reports that were deemed to have excellent reliability and are within the unknown category. Then we're down to 71 cases which equals around 3% of all reports investigated.

I am not sure what the point of all that actually is. Do you really not understand that the more reliable a report is (in terms of observer experience, training and fact-reporting ability and report consistency, completeness and quality), the less likely eyewitness error is to be involved? Please tell me what it is you do not understand about that.

I stated:
”In the Battelle study, 21.5% of the UFO reports analysed were categorised as “UNKNOWN”.
And the overwhelming majority of those remain unexplained because the reports are not reliable. What's your point?

Maybe you should focus on reports that were deemed to have excellent reliability and are within the unknown category. Then we're down to 71 cases which equals around 3% of all reports investigated.
The reports were categorised as unknown because:
”This designation in the identification code was assigned to those reports of sightings wherein the description of the object and its maneuvers could not be fitted to the pattern of any known object or phenomenon.” (http://www.ufocasebook.com/pdf/specialreport14.pdf)​
However, you seem to be forgetting that if you consider a report to be unreliable, then it simply cannot be categorised either as “Unknown” or “Known”. That is, such reports simply cannot be categorised at all - and must therefore be discounted from any analysis.

What you are falling victim to is a basic statistical fallacy that can be illustrated in the following example:

Total reports = 45 and are broken down as follows:
Reliability Poor:
Known = 10; Unknown = 5
Reliability Good:
Known = 7; Unknown = 8
Reliability Excellent:
Known = 5; Unknown = 10​

You are then stating that because two categories (Poor & Good) are not reliable enough for you, then only 10/45 are “Unknown” – when in fact 23/45 are “Unknown”. The fallacy you commit is that if you discount the 13 “Unknowns” in the Poor and Good categories, you must also discount the 17 “Knowns” in those categories as well! That is, you cannot say that the reports are reliable enough to determine “Known” yet not reliable enough to determine “Unknown” (either the reports are reliable enough to make a categorical determination or they are not). This is basic stats 101.

Now - if you do want to discount the less reliable reports in the Battelle analysis, then in consideration only of the most reliable reports (those made by military observers), then thirty eight percent (38%) of those reports were categorised as “Unknown”!

The overall “take home message” in this part of the Battelle analysis is that more reliable the observer, the less likely the report will be able to be classified as known. I have already stated:
The UFO debunkers have claimed for a very long time that there is only a very small and insignificant percentage of UFO reports (perhaps 3–5%) where mundane explanations cannot be found - and it must be stated that many UFO proponents have simply swallowed the unfounded assertion hook, line and sinker - without any critical assessment as to its veracity.

I am not sure what the point of all that actually is. Do you really not understand that the more reliable a report is (in terms of observer experience, training and fact-reporting ability and report consistency, completeness and quality), the less likely eyewitness error is to be involved? Please tell me what it is you do not understand about that.

Yes, I understand that. I also understand that you have not yet provided evidence to back up your statement that "research also shows us that there is a core of around 20% of cases where the information is reliable enough that eyewitness error is not a plausible explanation".

I stated:
”In the Battelle study, 21.5% of the UFO reports analysed were categorised as “UNKNOWN”.

The statement of yours you've been asked to provide evidence to support is "research also shows us that there is a core of around 20% of cases where the information is reliable enough that eyewitness error is not a plausible explanation". Now, are you going to provide evidence to support that statement, or are you going to retract it?
 
Round and round we go...

The overall “take home message” in this part of the Battelle analysis is that more reliable the observer, the less likely the report will be able to be classified as known.
However, this was considered irrelevant.

First of all, only 9.7% of the sightings were considered to be made by presumably reliable (“excellent”) observers.

[isn’t statistics fun?]

Secondly, out of the 434 sightings identified as UNKNOWN, only 12 were described with sufficient detail such that they could be considered GOOD UNKOWNS.

[regardless of who reported it]

Furthermore, contrary to your assertion, it was thought the rest of the UNKOWNS could easily have been mundane objects.

[again, regardless of who reported it]

Finally, out of the only 0.5% of sightings identified as GOOD UNKOWNS, precisely zero could be considered as evidence of “a novel, airborne phenomenon, a manifestation that is not a part of or readily explainable by the fund of scientific knowledge known to be possessed by the Free World” after further analysis.

As Jocce put it, what's your point?

Our (the skeptic's) point that renders this entire thread an epic fail on your part because you refuse to acknowledge it…

[overly dramatic emphasis mine]

“In general, the data were subjective, consisting of qualified estimates of physical characteristics rather than of precise measurements. Furthermore, most of the reports were not reduced to written form immediately. The time between sighting and report varied from one day to several years. Both of these factors introduced an element of doubt concerning the validity of the original data, and increased its subjectivity. This was intensified by the recognized inability of the average individual to estimate speeds, distances, and sizes of objects in the air with any degree of accuracy. In spite of these limitations, methods of statistical analysis of such reports in sufficiently large groups are valid. The danger lies in the possibility of forgetting the subjectivity of the data at the time that conclusions are drawn from the analysis. It must be emphasized, again and again, that any conclusions contained in this report are based NOT on facts, but on what many observers thought and estimated the true facts to be.” [pp. 4-5]​
Extraordinary claims require extraordinary evidence.

This isn’t it.
 
And if the report is not reliable, how valuable is it to even try and fit its characteristics with any known object?
However, you seem to be forgetting that if you consider a report to be unreliable, then it simply cannot be categorised either as “Unknown” or “Known”. That is, such reports simply cannot be categorised at all - and must therefore be discounted from any analysis.

Exactly. And yet you continue to claim at least 20% of ALL 2199 reports being unexplained in mundane terms. Focus on the 3% that are left, thats what I said.
