On the Frustration Inherent in Debunking

On the Frustration Inherent in Debunking


There is an interesting - and frustrating - phenomenon related to debunking: the time it takes to make a false statement is nearly infinitesimal in comparison to the time it takes to debunk it.

Example 1: Science thinks humans have spoken language for about 10,000 years now. 
That is a number I made up out of thin air. Now, debunk it. (Wikipedia doesn't count as a source.) This claim obviously belongs to linguistics, although it also somewhat overlaps with anthropology, evolutionary biology (and therefore paleontology) and maybe to some extent some other sciences. At least there's a starting point! (For some of the claims I've come across this far, the starting point is, well, obvious but in a way that does not help much. I will elaborate on that later.)

Then one has to locate a source, evaluate if the source is credible, ... So, making that claim up and writing it took all of ten seconds. Debunking it took a bit of thinking, a survey through the online databases of books available at the local libraries, checking whether any of the authors actually are authorities in their fields, finding books that are sufficiently new and also peer-reviewed, a trip to the particular libraries that happened to have such books available, (in the worst case, waiting for the previous person to have borrowed them to return them. Here, that makes a few weeks in worst case), and reading through sufficiently many chapters to find a clear statement about how long science does think humans have had language. A procedure that takes some time. In this case, the reason I would think the claim is spurious if I came across it is because I've heard a quite different date in linguistics 101, and in some other literature on the topic. I don't keep a log of every bit of knowledge I come across and what sources I can refer to when I want to repeat such a claim.)

I ended up with Tecumseh Fitch's The Evolution of Language. Of course, Fitch's book does not in its table of contents give a heading that says right out that a particular chapter contains the age of human language (or at least terminuses a quo and ante quem).

Here already, I am cheating a bit: had I not known that my claim was bullshit in the first place, I doubt one source would have been satisfactory to establish that science does think differently - science is not the statement of one scholar, but in a way some kind of weighted average of lots of scholars. Of course, there may be sources from earlier centuries, from religiously inclined scholars, other fringe scholars, etc, who will make claims that are quite far off from these estimates, and some of these scholars may even have some respectable credentials. Oftentimes, such credentials were given in times when science was less rigorous or had less evidence. Some get their credentials from colleges that are ideologically driven and do not even try to keep up with real science.

One big hurdle here is the availability of books: not all libraries have books that answer each question that might appear, and not even a university's access to electrical libraries and journals might provide sufficient material to verify or debunk each and every claim.

I have, in fact, gone through this procedure with some claims that turned out to be accurate as well. Here appears an important fact as well: the fact-checker is fighting up-hill. Sometimes, there is going to be the same effort invested no matter whether you are verifying a fact or debunking it. If the source you are investigating provides several minor supporting facts that are accurate and some major facts that are fabrications, the fact-checker runs into a frustrating situation, where he will end up evaluating a lot of claims for naught, even though the main thesis he is debunking indeed is wrong.

Still, it is clear that whoever is willing to mislead others has a great advantage, and if their readers are willing to be duped, the advantage is even greater.

Tecumseh Fitch does provide a terminus ante quem:
At a fundamental cognitive level, we humans are one species, each population possessing equivalent intellectual and linguistic capacities. This key fact enables us to infer with certainity that human linguistic and cognitive capacities were already fixed in our species by the time the first wave of human pioneers exited Africa and made it to Australia - at least 50 KYA (for a review, see Mellars, 2006). This time point (which is still controversial) represents the last plausible moment at which human linguistic abilities like those of modern humans had evolved to fixation in our species. [1, p. 273]
A worse kind of claim is those where even if a starting point is obvious, this still doesn't narrow the field down. This comes in claims like the similarity between some word in the Mayan language and Tamil, or unspecified similarities between Mexican and Hebrew [2, chapter 24] - both of which are important claims for Murdock's more wild theorizing. There are several Mayan languages, Katzner's The Languages of the World lists ten [3, p. 8]. Looking up the source provided by Murdock is a dead end - it only states this as a fact, not giving any source in which to verify it. [4, p. 9]
Now, I do not have access to dictionaries of these languages, and if I found a distinct lack of that word in a dictionary, there could be several explanations: it is a word in another Mayan language, it is a dialectal word that would not be included in a dictionary, it is a derived word form that is not included in a list of roots, ...

There is literally a dozen ways to wriggle out of being caught with one's pants down in that case. It is an unfalsifiable claim, as any attempt at falsifying it only leads to increasing amounts of work for the person investigating it with a skeptical mindset: ultimately, I will have to learn the ten Mayan languages (and the eleven other ones that appear in some other lists), all the extinct versions, and go to each and every village checking if the word actually exists there.

Obviously, science cannot work that way - its hands would be tied by those who would wish to mislead, having to spend all its time in a defensive posture against fabrication. This is why proper sources are required. A religious Hindu newspaper is not a proper source.

As for claimed similarities between Nahuatl and Hebrew, the supposed kind of similarities are not even mentioned. People with an interest in linguistics knows there are many dimensions along which a language can be similar: their grammars can behave in similar manners (as in the case of Finnish and Turkish, or Swedish and English, or ancient Greek and Russian), their vocabulary can be similar (as in the case of the Romance languages and English, or the Germanic languages and English), their phonologies can be similar (Norwegian and Swedish, Estonian and Finnish, Russian and Polish, Polynesian languages and Japanese, Tamil and Marthutunira). Of course, the person making such a claim probably is unaware of all these ways in which languages can be similar (or different).

Of course, this makes the person that is knowledgeable about these matters and who wants to do a really comprehensive debunking likely to run into problems: he will want to debunk every possible claim that he can imagine here (or at least show that what is claimed to follow from such a similarity does not follow).

Ultimately, a line must be drawn somewhere - vague claims that are not given sources at all (or where the source does not back its claim up) cannot be dealt with. The author has been dishonest, and misleading in not making a clearer claim. The claim must be rejected until a more specific claim can be provided instead.

And this is a trick Acharya S repeatedly uses.

Acceptable errors?

Even in real, serious, scholarly literature, errors will creep in. No one can know all the fields that modern science and technology (or other scholarly fields) utilize. A favorite example of mine appears in some editions of Peterson and Davies' Computer Networks, A Systems Approach. It is a good book, well deserved of its position at many universities as the textbook for courses on networks. One minor error has sneaked in that I have noticed - and a really inconsequential one, at that.
First, there is the speed-of-light propagation delay. This delay occurs because nothing, including a bit on a wire, can travel faster than the speed of light. If you know the distance between two points, you can calculate the speed-of-light latency, although you have to be careful because light travels across different mediums at different speeds. [5, p. 42]
 This text by and large is correct, the minor error being that information in fact can travel faster than light when light travels slower than c under exceptional circumstances. The text implies that the speed of light in a medium is the fastest anything can travel in that medium. Now, this is incorrect. Nothing can surpass the speed of light in vacuum, in any medium would be a more accurate wording. Of course, this does not even get into the issue of phase velocity vs. group velocity.

We know by now that light can be slowed down to about 20 km/s. Simply sending information encoded in neutrinos through such a medium would violate the claim made there. However, no one will run into that in any situation where information is being transmitted for quite some time or for the purpose of actually transmitting information, and other situations in which information actually are transmitted faster than the speed of light in the medium are so exceptional as to make the claim in the text acceptable - the possible methods to do so are so impracticable they probably never will see any actual implementation. Counterexamples pretty much only serve as proofs of concept, and this is not even an issue in physics.

Ultimately, we conclude that this mistake isn't even a problem: no alternative physics or models of networks is being proposed on the basis of this claim in the book, and in practice, it will actually be correct as far as engineers of electronic communication are concerned for the rest of, well, probably all of history. However, no physicist will quote this book as evidence that modern physics rejects the notion of communication faster than the "local" speed of light in a medium - since the book is not written by a physicist, not meant to teach physics, and not a source for statements about physics. If a paper on physics referred to this volume in regard to physics, the student's advisor would do well to suggest another source be used. If the student referred to this volume in regard to some algorithm or solution used in electronic communication and investigated some physical solution to a problem mentioned, the student could very well refer to this book even in a physics paper - but even in that case, the book is only an authority within its field. (Even then, the student would do better to refer to some more up to date source about the particular problem.)

Is the flipped coin fair?

In maths, there is an interesting problem: how many times do you have to flip a coin (or dice) before you know (to some level of certainty), that the coin has been tampered with to increase the likelihood of one side over the other. Turns out we can never know for sure (without actually measuring the weight distribution of the coin or something), but we can know with some certainty. The more tests we perform, the closer to 100% certainty whether it's fair or not we reach - but we never get quite there.

Knowing the maths, we can also do this for a dice, or other sources of random numbers. Now, it would be joyous if we could do the same for scholars. How many claims do we have to investigate before knowing whether a scholar is crooked or honest, credulous or scholarly? I have already showcased an irrelevant error - one where the error did not substantially alter the quality of the work it occured in.

The scholarly community doesn't have a formal line an author has to pass to be rejected as a crackpot. If there were a good way of calculating the likelihood that someone was a crackpot based on the number of mistaken claims, that would be very useful. Refusal to go through peer-review yet maintaining that one's research (generally from secondary and tertiary sources) is ground-breaking is an important indicator. Sometimes, brilliant scholars in one field publish crackpot material in another. The psychology behind that is difficult to understand.

However, to let the claims made stand for themselves, I've decided to read her material and let it speak for itself, rather than allegations and aspersions as to her motives. So, we get back to the tedious fact-checking. Obviously, some claims do tend to have greater gravity than others, and to be more important for the conclusion than others - a sufficient sample of fabrications among them should be a good start? Is a sufficient sample of erroneous factoids given in support of the thesis also a good indicator?

Here the analogy to the tampered-with coin comes in: a reasonable sample of fabrications, errors and distortions should be sufficient to establish that a scholar is not credible - whether he or she intentionally is duping us, or is just lost in a maze of delusion or misunderstanding. Alas, I cannot make a definite statement that this or that claim in particular was the straw that broke the camel's back - but anyone who sees the sample of downright bullshit I will quote and debunk here must conclude that she is not a credible scholar.

Minor further observation

Of course, the charlatan has another advantage. Many charlatans of Acharya's kind sell something. There is a market for conspiracy theories. The market for debunking conspiracy theories is much much smaller - among her readers, few will be interested in a volume the raison d'etre of which is to take her to task for shoddy scholarship. This, combined with the imbalance between the charlatans and the defenders of reason that I already described, creates a situation where charlatans can thrive - debunking them simply does not pay off.

Just think, who would buy a book whose only purpose is showing another book (or some other books) wrong, without presenting any more groundbreaking theory than "the scholarly community, by and large, are right about things, and the things they're wrong about are either minor things or things that will be corrected as academia finds and evaulates new evidence"?

Even further suspicion

I wonder when a cease-and-desist letter will hit me over this - as I do use a fair share of quotes (but these quotes can be justified the way Acharya justifies her excessive quoting). If it happens, I will maintain my quotes fall under fair use. If a cease and desist note never arrives, I will be quite happy, and I will respect Acharya at least a bit for that. If one does, well, in that case I hope the sender of it tells me how to show that I am not misrepresenting the material I am debunking and also make it clear that I have actually read the books. C.f. how a fan of Acharya's accuses a critic of not having read the book in the first place.

On Acharya S

[The review of The Christ Conspiracy has now been completed. There is a summary, as well as a two-part synopsis (part 1, part 2)]

I have been reading a lot by D.M. Murdock recently. Her books moved me to start this blog.

I do hope many of her fans will read my posts on her books - the first series of posts I have planned out is basically an in-depth review of her books The Christ Conspiracy, Christ in Egypt and The Suns of God.

I am not the first to do this, but I have found a bit of an omission in the reviews and criticisms I've read: most are written by theologians. This, per se, is not really a problem, but it has some effects that may be problematic:

  • Her fans may see theology and especially academical theology and its representatives as a conservative, hostile bunch of ivory-tower residents that want to keep outsiders out, and who often are inclined to side with Christian orthodoxy. To some extent, this is even an accurate objection.
  • Murdock makes several claims that are not of a theological nature. She especially likes to use claims that are of a linguistic nature (see chapter 16) (but also, consider the quality of the linguistics in her sources, e.g. Barbara Walker, Drummond). I do not expect theologians to know when her use of linguistics is shoddy or misleading. Considering she claims to be a Greek scholar, it is interesting how ignorant she is of linguistic methodology and of how language actually works. It seems she subscribes to some kind of very anglo-centric view where English names of things convey something essential about the thing (see "God's spell" as an informative example). As if English were a magic lens into the essence of every concept, and that other languages somehow imperfectly reflect these.
  • Her reasoning often fails at being logical. Now, as a computer science student, logic is a central tool I use quite regularly, and I understand a fair bit of it. Some of her flawed reasoning may not be as readily obvious to someone more into subjects such as theology. I am not saying that theologians are necessarily illogical, but some illogical things may pass them by (and sometimes members of their ranks concoct fairly illogical reasoning as well). In the interest of completeness, I have decided to point out flawed reasoning wherever I see it, even though others have pointed out the same flawed reasoning.
  • My interest in pragmatics and linguistics in general has made me aware of how she phrases things. She casts aspersions both left and right frequently, and at times she includes statements that do not really support her specific thesis, but to the credulous reader are further proof of a conspiracy to hide the facts.
Now, as a non-theologian, I am not very well-versed on Church history, and it is in fact a topic I don't care that much about. To some extent, I will check sources regarding her claims, especially whenever the claims are so egregious that even I can spot them. Chances are, though, that I will fail to spot some of her mistakes.

I will criticize her sources' quality as well, as her writing uses such considerable amounts of long quotations that it at times reads like a "best of" record of secondary and tertiary sources. She seldom actually engages with the texts, never pointing out flaws or mistakes in them. This far, in my reading, I've only come across one instance of engaging with a text instead of accepting it at face value: she pointed out that the author of the relevant source was a believing Christian, and therefore possibly a bit too uncritical (irony of ironies). Other than that instance, she never questions a source - not really a thing one can do in  books she wants to claim to be comparable to PhD theses:  "as concerns my credentials and continuing education, I would like to consider my books Suns of God and Christ in Egypt in particular a PhD thesis in the subjects of comparative religion and astrotheology."[1]

Sources are not taken to task for bad methodology or tendentious claims, and for that reason I will investigate some of her sources with a skeptical mindset as well. On the other hand, she also uses the time-tested method of quote-mining, which means some of her sources only say what she claims once the context has been removed. Since I have not been able to get my hands on all her sources, and time, alas, is a finite resource, I have not been able to check every quote for quote-mining. Archive.org helps a bit - many of her sources are public domain now, and some have been scanned by Google, Microsoft and so on, and are available there. 

She generally prefers old sources - a thing I do understand, given what she wants to say, but not given that she wants to be scholarly. She has to realize that methodology has developed since the time when these sources were written, that old claims have been debunked, that what scholars in the 1880s to 1930s thought is not current - several of her sources predate that time as well, especially Higgins who is a prominent source throughout The Christ Conspiracy. Sources from those times subscribed to ideas of how religion evolved that misconstrued evidence to show how Christianity was the apex of religious evolution. Her sources by and large did not buy into that model, but built their own opposite model that had just as mistaken assumptions - they posited religion as an increasingly corrupted version of an ancient perfect lore. Both models misunderstand evolution, and both are basically terribly unimaginative approaches - the devolutionary model basically turns the evolutionary model on its head, instead of coming up with a tenable explanation. Her sources were seldom peer-reviewed in their time, either, and thus are rife with speculation and bad reasoning. (For an example of such sources Godfrey Higgins comes to mind. An in-depth, but still incomplete look at his works, see 1, 2, 3. Another example of rather shoddy sources she uses is Karl Anderson, a 19th century astrologer. A third and fourth example are the brothers Churchward.)

A more modern source whose reliability is questionable, but whose work is referred to throughout The Christ Conspiracy is Barbara Walker, who often misunderstands what her sources claim, and uses similarly unreliable sources for her research.

As academia has worked on these things methodology has been refined and mistaken interpretations of old evidence have been debunked. Alas, Murdock does not care to keep up with sound methodology.

There is one type of fallacious claim she likes making again and again, even in contexts where they are red herrings. These are fallacies of an etymological nature, and therefore, I've decided to gather an overview of the types of mistakes she makes in one separate postThere also is one chapter brim-ful with this kind of mistake. I fear many readers of her books may be very confused as to how etymology works, what it means for a word to have a certain etymology, or how etymologies are researched. I will go into some detail on that particular topic in separate posts. 

Alas, her sources too tend to make the same kind of mistakes, and thus, I will deal with mistaken claims in the quoted works simultaneously with mistakes in her own book. In fact, it seems she has been rather clever when it comes to this: very seldom she makes a factual claim that is (verifiably) wrong. Very often, she lets others make them for her!

Although I do not subscribe entirely to the sentiment she quotes from Wheless, it bears repeating:
"... If the Gospel tales were true, why should God need pious lies to give them credit? Lies and forgeries are only needed to bolster up falsehood: "Nothing stands in need of lying but a lie"". [2, 3]
The amount of falsehoods used to prop up her claims should be taken as an indication as to the veracity of her claims. Alternatively, we realize that the number of falsehoods used to prop up something does not necessarily make it false - it is trivial to make up a falsehood with which to prop up a truth.

Now, I am no Christian. Nor have I been for over ten years. I dislike many - possibly even most - explicitly Christian beliefs. However, I do not believe fabrication is a thing we should take to when trying to debunk Christianity. This, alas, is what D.M Murdock participates in - intentionally or not. As a person with some kind of integrity, I feel I have to point out and debunk the false claims made in her books, and make Christianity's opponents less likely to be misled by her. Just because an argument against something sounds persuasive, the argument is not necessarily correct. Christianity can be wrong without her arguments. In fact, I am convinced Christianity is wrong yet  believe in very few of Murdock's claims. I am certain that we can argue against Christianity from a stronger position if we refrain from using her false claims, as well as other false claims.

I write this, in part, because I know how frustrating it is to face someone whose view of the world is - to say it kindly - fanciful, in part because with sources like her, atheists arguing against Christians will deservedly lose whatever debates they get themselves into if their Christian opponents are even reasonably well educated. 

When some claim of hers almost gets it right and can be corrected - and in its corrected form can be used against Christianity (or is a reasonable fact for other reasons), I will point this out. I will also point out what bits she does get right in fields about which I dare to make such comments.

POSTSCRIPT: On December 26, 2015, D.M. Murdock passed away after having battled cancer for a while. Although I have written critically of her works and claims, I held no grudge against her as a person, and am saddened that she had to face such a terrible and early end. Her works improved throughout her career, and had she seen a full lifespan, she could even have produced works of lasting value.
