What’s the difference between a donkey and a UFO?

I recently came across another piece of inane blather from a self-styled paranormal “expert.” And it’s just too good to pass up.

This blog, Bad Thinking, is dedicated to exposing the logical fallacies and poor arguments used by the promoters of, and believers in, woo generally. I’ll not name the “expert” in question, but some people might take an educated guess – it’s more guff about UFOs, after all.

Like a lot of fallacies, this falls into an area of overlap, so to speak. And a lot of fallacies do. This could be called a category error, or it might be called a false analogy. It also comes under the heading of the appeal to popularity and, in the context of the original article, the appeal to authority. It’s one of those errors of reasoning that doesn’t fit neatly into one specific slot, but it’s an error of reasoning, nonetheless. But it’s also an exemplary example of how to fit so many fallacies into so few words.

First of all, I will give the relevant quote from the newspaper column I found it in. Here we go:

If 1,000 independent witnesses tell me they’ve seen a donkey running down the middle of King Street, odd though that may be, I’d be pretty tempted to believe them.

Why? Because the idea so many people would independently decide to tell such a fib without any apparent motivation is far more difficult to swallow than the idea of a donkey running down the street.

DonkeyThat’s from an article promoting the idea that UFOs and their alien pilots are here, but that it’s all being covered up by governments around the world, and we should all believe it because, well, you know, why demand evidence when other people say they’ve seen it – just believe what you’re told: lots and lots of people say so; what more do you need? And this author makes a living from writing about what other people say. Yeah, right…

Here’s a brief analysis of this published piece of certifiable bad thinking:

The fact is that

  • 1: There is no doubt that donkeys are real.
  • 2: There is plenty of justifiable doubt about the existence of aliens and their space ships visiting this planet.
  • 3: Unproven claims of UFOs are entirely different from claims about established facts (they are in different categories).

It wouldn’t take a thousand witnesses to convince me that they had seen a donkey running down the middle of my local High Street. Even if it seems unlikely, I would probably reserve judgement until I got some further confirmation (a report in the local newspaper, say) but I wouldn’t be too worried about it. After all, there are news reports from time to time about escaped animals causing havoc, so the idea of a donkey causing inconvenience to some local shoppers would be unusual, but not totally implausible, and certainly not impossible.

It wouldn’t even matter if just one person told me he had seen it himself, even if he just happened to be a pathological liar who had fabricated the whole story just to wind me up. That would not alter the fact that donkeys are real, and that no one disputes their existence.

UnicornWould the author of the article believe what he was told if a thousand people informed him that they had seen not a donkey, but a unicorn running down his local high street? Like UFOs, no one has presented compelling evidence – and especially not proof – of the existence of these mythical creatures, so believing an uncorroborated report of what is certainly an extraordinary claim would be irrational.

The same goes for UFOs. These alleged alien spacecraft are not proven to exist, however many former astronauts and military personnel claim to have had access to aliens and their technology. Many of these people are making a handsome living from their books, articles, public speaking engagements, television appearances and so on. But not one of them has provided testable and confirmable evidence of any of their claims.

Has NASA been exploiting alien technology since the so-called alien flying saucer crash in Roswell in 1947, as many conspiracy “theorists” assert? You might want to believe it, but I would point out that rockets are still using chemical propulsion to get into orbit, not anti-gravity devices. Has transportation been revolutionised by teleportation technology, or are we still using cars, trains and planes? Can anyone prove that the truly massive structures being designed and built nowadays are being put together using the same alien technology that some would have you believe was the only way that the ancient Egyptian pyramids could have been built? Is humanity so stupid that we can’t do anything ourselves on a big scale unless someone else from light years away just provides it for us?

To put it plainly:

  • The number of people who make a claim is irrelevant to the claim’s veracity (that’s the appeal to popularity).
  • The status of those people is also irrelevant, even if they are former military personnel or astronauts (that is the appeal to authority).
  • Claiming a link between things that have no connection is a category error, and also quite often an argument by false analogy.
  • Extraordinary claims require extraordinary evidence; hearsay just won’t do if you want to be taken seriously.

The author of the article obviously thinks that claims about donkeys (which exist) are equivalent to claims about aliens (for which there is no evidence to show). He is wrong. Maybe he believes in flying horses and talking ants. Who knows?

So the difference between a donkey and a UFO is simple: one of them really does exist; the other has as much evidence available for its existence as there is for unicorns, i.e., none at all.

Belief without evidence is called faith, and it is also bad thinking.

Can Skeptics Handle The Truth About The Unexplained?

I got a sudden upsurge of traffic on the blog a couple of weeks ago after my last post. Mike Hallowell’s article claimed that a Neanderthal had been shot dead by time-travelling hunters using modern firearms. The article was picked up for criticism elsewhere, here, for example, so it obviously made an impression.

Since then, Mike has published a follow up article in the Shields Gazette, but rather than accepting that he made several factual errors and had fallen into various logical fallacies he has, in fact, dug himself deeper into a factual and logical hole. Let’s have a look.

The title of his article doesn’t start things off very well. It says,

Some can’t handle the truth about the unexplained

If something is unexplained, then it is unexplained. The only truth about the unexplained is that it is just that. What is the alternative? Maybe the usual, “We don’t know what this is, therefore aliens.” (Occam’s razor would come in useful there, and as it happens I am already busy drafting a post on that very subject.)

Mike starts his article with the statement (I have added bold for emphasis, and my comments are in square brackets):

MY recent article about an ancient animal skull and a human one which appeared to have a bullet holes in them created quite a bit of interest; more than any other column of mine this year, in fact.

That’s not just misleading but flat out wrong, because he stated specifically that it was a Neanderthal; there was no mention of a human being as the subject of the story. (I know from experience that Mike Hallowell will probably now accuse me of accusing him of being a liar, so I will make this as clear as I can for him: I am not claiming that Mike Hallowell is lying, I am claiming that he is contradicting himself; I have provided the links, and even if those Gazette articles mysteriously disappear for any reason, I also have copies of them that I can produce later.) He said in his previous article:

It was, in fact, a Neanderthal skull, and Neanderthal bones did not exactly come ten-a-penny. [Not in Africa anyway, at all.]

And:

As there were no radial fractures on the Neanderthal skull, it was unanimously concluded that the projectile must have had a far, far greater velocity than an arrow or spear. [Concluded by whom? Mike doesn’t say, so it’s not going to be easy for any (qualified) researcher or anyone else to follow up.]

As I pointed out in my previous post, the skull in question is neither human nor Neanderthal, although it is probably an ancestor of both. Although Mike said in his original article that the skull was Neanderthal, he now says he was writing about a human skull. (Pick the bones out of that. (as it were))

Mike’s response to those who pointed out to him that Neanderthals did not live in Africa is:

Really? And they know this how, I wonder? Absence of evidence is not absence of evidence. It is likely that Neanderthals did inhabit parts of Africa. [I think Mike means “Absence of evidence is not evidence of absence,” Carl Sagan’s famous quote.]

No, the absence of evidence of any Neanderthals in Africa indicates it is unlikely they lived there, and almost certainly did not. In any case, this is a red herring – the skull referred to in the original story is definitely not a Neanderthal, despite Mike’s original claim, and the main question (perhaps) is whether it was shot at all, never mind whether time-travellers did it with a modern firearm.

Mike says that “even if” the existence of Neanderthals in Africa is unlikely, he says that the absence of evidence doesn’t mean they didn’t live there, just that “…they may not have.” He doesn’t see the need for a positive claim to have positive supporting evidence before it can be taken seriously. That is basically the appeal to ignorance – the idea (whether stated explicitly or implicitly) that if a claim cannot be proven false, then by default it should be accepted or at least be given serious consideration. Then again, no one has found kangaroo fossils in Africa, so should we accept the possibility they evolved there with no evidence for that either? They haven’t found polar bear fossils in Antarctica; what should we make of that? It doesn’t prove they weren’t there, after all.

Mike reckons that sceptics are most upset at the idea that ancient people might have developed technology even more advanced than our own. He asks:

On what logical basis can we say that?

The logical basis is called induction. Archaeology and palaeontology have discovered tools and other artefacts that are associated with mankind’s evolutionary development, from stone axes to more advanced technology through the ages. Nothing equivalent to modern power tools, computers or other technology has ever been found at ancient sites.

Mike says it is extreme arrogance to suggest that no ancient peoples were our equals when it comes to “…their understanding of the sciences”. There are a number of links in the article, but good luck trying to get through to them. For me, all but one went to a “page not found” link, and the one I did get through to is nothing but the usual sensationalist and highly speculative rubbish that has been repeatedly debunked. And no, even if you can find the video of some astronauts claiming UFOs are real (and there is no shortage of them on Youtube), the number of people making an unsubstantiated claim does not make such a claim true. That’s the appeal to popularity – also a logical fallacy. It doesn’t matter how many people make a claim, it is of little use without corroboration.

(I’ll add a note here about that. A constant refrain from the woo people is that eyewitness testimony is allowed in a court of law, so it should also be “admissible” as evidence of paranormal claims. What they seem to be unaware of is that such testimony in court is subject to cross examination, and is still considered weak at best if there is no corroboration; if sufficient doubt is raised in the minds of a jury, then a defendant must be found to be not guilty, and a Crown Court Judge will tell a jury that that is the law. Sceptics also have their doubts when a paranormal claim is made without testable evidence to back it up.)

Mike then bemoans the fact that sceptics hold science in such high regard. He wants to know why “supposedly intelligent people” deny his claims. He says:

The answer lies in the obsession that some sceptics have with insisting that scientific testing, experimentation and observation are the only reliable means of establishing the veracity of something.

Well, when you can pick and choose your own criteria for establishing truth, and ignore completely such things as multiple eyewitness testimony, you’re on a pretty safe bet, of course.

Whether Mike likes it or not, science is the best method we have for finding out about the universe we live in. A subjective assessment of claims is worthless if you are asserting that a claim is an objective fact. It is the paranormal fraternity who pick and choose their own criteria for “establishing truth,” but they have to be anti-science because science requires testable evidence of any claim made – eye witness testimony is not scientific.

And:

So what do you do with those pesky eyewitnesses who insist they’ve seen things you don’t want to believe in?

Maybe accept that they have just been “seeing things”? Mike believes that sceptics respond with character assassination and various ad hominem attacks, but he does not accept that in fact the various claims made by  paranormal proponents are rejected because of a lack of credible evidence to support them.

He doesn’t help his argument by stating that there are various astronauts who make public claims that aliens are here. As he puts it:

They’re either outrageous liars, or they’re telling the truth, I’d venture.

That fallacy is called a false dichotomy – offering only two alternatives when there are others. Perhaps those witnesses are delusional, or maybe they have been given false information and they truly believe it. I can think of other possibilities, but Mike thinks they should be believed because he sees “…no reason for them to fib.”

Paranormal buffs like Mike criticise science, commonly saying things like, “science is always changing its mind about things.” But look at it this way: someone claims that a Neanderthal skull has a bullet hole and the force of the shot destroyed the opposite side of the skull. That’s a testable claim because the skull exists and can be examined.

Scientific examination of the skull reveals that it is not that of a Neanderthal anyway. It turns out that the “bullet hole” shows signs of healing, so the individual did not die from the wound. Evidence also suggests that it may have been caused by an infection in the overlying tissue. And, despite what he said, the opposite side of the skull is intact, and definitely not showing signs of a bullet’s exit wound.

All of that has been pointed out to Mike Hallowell, but not only will he not admit that he got it wrong, he defends his original article with self-contradictory statements and logical fallacies, and criticises science – the very discipline that could have upheld his claim if only it were true.

So it turns out that the skull in question is not a Neanderthal and it wasn’t shot dead by time travellers using a modern firearm. That’s the truth and yes, sceptics can handle it. There was nothing paranormal to explain n the first place.

Was A Neanderthal Shot Dead By A Time Traveller? No.

This week’s Wraithscape column in the Shields Gazette seems to be a record-breaker for cramming so much nonsense into such a small space.

images (2)The claim made is that in 1922 a Neanderthal skull was found in South Africa, but that it had a bullet hole in the left side of the skull, and that the opposite side of this skull had been “blown away.” As Mike Hallowell puts it:

In short, whatever had hit the Broken Hill Neanderthal on the left side of his head had passed through it with such force that it had caused the right side to explode.

That sounds like the type of wound that would be caused by a high powered rifle. And, of course, some unnamed forensic experts have concluded:

The cranial damage to Rhodesian Man’s skull could not have been caused by anything but a bullet.

The same article also makes a similar claim about an ancient aurochs – an ancestor of modern cattle, but I’ll not bother with that bit of claptrap; the Neanderthal “shooting” is more interesting.

The whole article is full of factual inaccuracies. First of all, the skull referred to was found in 1921, not 1922. It’s a relatively minor point, but still a factual error.

More important, however, is Mike Hallowell’s claim that the skull in question is that of a Neanderthal. He says:

It was, in fact, a Neanderthal skull, and Neanderthal bones did not exactly come ten-a-penny. [Emphasis added.]

In fact, Neanderthals were never in Africa. The skull is now identified as Homo heidelbergensis, with the evidence suggesting that it is an ancestor of both Neanderthals and modern humans. Neanderthals are on a different branch of our evolutionary tree and their remains have only ever been found in Europe. Not Africa.

But what about the bullet hole and the large exit wound? The “bullet hole” shows signs of healing, and was most likely caused by an infection in the overlying tissue; it certainly did not kill this individual. As for the other side of the skull that supposedly exploded as a bullet passed through, that is simply wrong. The opposite side of the skull is intact. There’s an interesting article about this particular skull at the Bad Archaeology blog.

Mike Hallowell thinks he has “forceful evidence” that thousands of years ago a Neanderthal was shot with a modern firearm, when in fact there is no evidence of the sort. And there is even less evidence for his other conjecture – that…

…someone from the future, carrying a firearm, travelled back into the past and engaged in some sort of trans-temporal hunting expedition.

Then Mike finishes his article with this declaration:

Like it or not, the fact is that someone or something seemed to be using high-velocity bullets thousands of years ago. We don’t know who, we don’t know why and we don’t know how – but it happened.  [Emphasis added.]

I have to say, I don’t mind a mystery, but a genuine mystery has to have a factual basis to make it worthy of examination. The only mystery here is how this drivel got into print.

For a brief, but scientific, account of the skull, there is a good article here at the Natural History Museum. For some reason, the scientists there just don’t seem to have recognised the “bullet hole,” the (non-existent) “exploded” exit wound, or any evidence of time-travelling hunting parties. What are they doing all day long? Don’t they read the Shields Gazette?
