New Book: I Told You So!

Quote: Science is going to be critical for tackling the big challenges that our society faces. … We need it operating at its best to tackle these problems and, while science might look like a well-oiled machine spitting out findings to those glancing at it from the outside, it looks more like a clunky old engine prone to breakdown to those of us on the inside. … In the pages ahead I am going to show how science, rather than being immune to the passions and politics of the outside world as it is meant to be, is shaped by these influences and increasingly being threatened by them. This is to all of our detriment. Yet, just because this is the way things have been does not meant this is the way they must remain. By studying how science has gone wrong in the past (and is going increasingly wrong today) we can learn how to keep it from going wrong in the future…. 1

Title: I Told You So!

Subtitle: Scientists Who Were Ridiculed, Exiled, and Imprisoned for Being Right

Author: Matt Kaplan

Comment: Kaplan is a journalist specializing in science who writes for The Economist magazine. I may have read some of his journalism but if so I don't remember. He's also written or co-written three previous books, none of which I've read.2

Date: 2026

Summary: I just got my hands on an actual, old-fashioned, paper copy of this book and have only just begun reading it. Based on the subtitle and what little I've read so far, the book appears to be a history of scientists who met social, political, or religious resistance to their discoveries. Kaplan writes:

Copernicus feared how the outside world would respond to his discovery that the earth went around the sun, and hid his notes away in a desk drawer…. He kept them unpublished until he was so seriously ill that he was certain he would be dead before the Inquisition could come for him. Contrary to popular legend, Darwin did not really fear that the public would lynch him for his theory of evolution, so much as worry that the rest of the academic community would think less of him for coming up with such a wild idea. … Others carefully managed their relations with the outside world. Galileo had to consider the church with every step that he took. Joseph Lister and Louis Pasteur…didn't hide their findings, but political games were essential to their survival.3

We'd like to believe that sort of thing no longer happens in these enlightened times. Unfortunately, the political games are not over, and I assume that Kaplan will discuss some more recent cases of science being delayed or nearly derailed by political or religious opposition.

The Blurbs: The book is positively blurbed by Bill Bryson, the author of one of my favorite reference books on easily confused words4.

Disclaimer: I haven't read this book yet and, therefore, can neither review nor recommend it, but it looks interesting enough to me to read and I thought others might also be interested. I may review the book in the near future if I have anything interesting to say about it, or at least if I think I do.

How to Lie With Notes 6: The Phantom Reference Menace

In previous entries1, we've looked at how scholarly works―or non-scholarly works trying to pass as scholarly―can have too few notes or too many. Now, it's time to turn to the ways in which individual notes can mislead.

We tend to rely on the notes of a scholarly work to support its claims, but they don't always do so. Few of us check notes, and even those of us who sometimes do so don't check them all. Many books that include notes often have too many to check, so misleading notes may go unrecognized, which just encourages those who resort to them.

A phantom reference is not a ghost note, which is a non-existent note, but an existing note that cites a non-existent work. While there probably were cases of phantom references in the mountain of pre-21st century literature, I expect that citations to non-existent works were uncommon until recently. A previous entry discussed a phantom reference from this century―in fact, a quite recent one―but one that appears to have resulted from a typographical error in the citation2.

In the current century, phantom references are becoming a more serious problem, especially with the rising use of so-called artificial intelligence ("AI"). "AI" programs have a tendency to cook up references to non-existent articles and books3, which is called "hallucinating", and some humans use such hallucinations without bothering to check them. Why "AI" does this is an interesting question, but one that is beyond the concern of this entry. However, we don't need to know "why", we just need to know "that" it does so, and take steps to avoid falling into the trap of accepting such hallucinated references.

Ultimately, the responsibility is on the human author if such fake citations make their way into a published work. If you use "AI" to draft an article or book for you, or just the references for one, it's up to you to check that those references are for real4. One reason that the phantom reference has become such a growing menace to 21st-century scholarship is that it can always be blamed on the "AI". In the past, a note to a fake work would have likely been a career killer for a scholar. Using manufactured citations is as much scholarly malpractice as plagiarism, and should be punished as severely.

Another basis for the rise in phantom references is the slighly less egregious practice of copying references from other works5. Once a non-existent source is cited in the notes of one author's work, other authors may beef up their references by simply copying those citations without checking them for authenticity. If an "AI" generated hallucination is hiding in that work's notes, it is likely to spread through other works like a virus. In the past, this may have been a relatively harmless practice since phantom notes were uncommon, but it always violated the principle that references should be to works that are used as sources: obviously, you can't have used a non-existent work as a source. Moreover, copying sources from related works is a pseudo-scholarly practice that makes it look like the author has done more research than the reality. It's lazy, as well.

Finally, at the risk of repeating myself, it's more important than ever for readers to randomly check at least a few notes in current research papers and scholarly works before relying on them. The phantom reference problem is likely to get worse as more researchers use "AI" to help them quickly and easily produce publishable articles.

Notes: I've intentionally included one phantom reference in the following notes: see if you can find it.

An Unmitigated Mistake

There are two problems with the following headline:

Marine reserves help mitigate against climate change, say scientists1

When I first saw it, I wondered what the Marine Corps Reserve could possibly do about climate change. Then, I read the article beneath the headline and discovered that its first two words referred to ocean sanctuaries for sea life, not amphibious soldiers.

So, the first problem with the headline is that "marine reserves", especially with a capital "M", is ambiguous. Later in the article, we learn that such a reserve is referred to by the bureaucratic phrase "Marine Protected Area", or "MPA" for short. Thus, the ambiguity in the headline could have been avoided by rewording it: "Marine Protected Areas help mitigate against climate change, say scientists".

Can you see the second problem? "To mitigate" is a transitive verb meaning to lessen the severity of something―usually a problem or punishment2. It's most commonly found in legal contexts in such phrases as "mitigating circumstances", which should lessen the punishment for an offense. The negative form "unmitigated" occurs in such hackneyed phrases as "unmitigated disaster", meaning a disaster without mitigating circumstances. Since "mitigate" is a transitive verb, there's no need for a preposition such as "against" to connect it to its object. If the article's writer really meant "mitigate", the headline should have left out "against".

However, it's likely that the writer was confusing "mitigate" with the similar-looking "militate", a rare word most often found in the phrase "militate against". "To militate" is an intransitive verb meaning to act vigorously in a positive or negative way3, and it takes a preposition to indicate whether the act is for or against something. So, the headline could have been worded: "Marine reserves help militate against climate change, say scientists". The erroneous "against" appears to have been introduced in the press release for the study paper, whose title uses "mitigate" correctly: "Marine reserves can mitigate and promote adaptation to climate change"4.

The phrase "mitigate against" seems to be a common error since most of my reference books warn against it5. One exception is Lite English by Rudolf Flesch6, who calls it "a very interesting case", and I agree. Flesch's book is a sort of reversal of the reference books on common errors in English that I cited in the preceding note in that he defends some uses that those books condemn. It's a glossary of words and phrases that he says are "OK to use no matter what" those he refers to as "purists" say, and he claims that science is on his side7―how "science" could possibly take sides in this dispute he fails to explain.

After explaining what "mitigate" and "militate" mean, here's what he has to say about the phrase "mitigate against":

The trouble is that the American people constantly mix up the two words. They say and write mitigate against when they mean militate against and they simply don't use the word militate at all.8

After an example of the use of the phrase "mitigate against" from the New York Times Magazine, he continues:

Twenty years ago the mistake would have been caught by the copyreader and if not, by the printer's proofreader. No longer. The Times is now riddled with misprints and mistakes of all kinds. I looked up this common mixup or idiom in all the dictionaries. Not a single one of them mentions this extremely common usage. … On the other hand, this "common mistake" is mentioned in virtually every book on English usage.

Despite referring to the phrase as a "mixup" and a "mistake", Flesch finally surrenders:

I'm afraid it's a lost battle. We might as well accept the fact that mitigate against is now an American idiom.

I think the main reason that "mitigate" and "militate" continue to be confused is that both words are unfamiliar and people don't know what they mean. Anyone who understands what "mitigate" means would never say "mitigate against", which is ungrammatical: would anyone ever write "lessen against"?

Here's a fast and filthy tip for remembering the difference between "militate" and "mitigate": "militate" is cognate with "military" and "militant", all of which descend from the Latin verb "militare", meaning to serve as a soldier9. So, to militate is to fight for or against something like a soldier. For "mitigate", just remember that to use it in the phrase "mitigate against" would be an unmitigated error.

"Mitigate against" is an "interesting case" for "non-purists" such as Flesch: according to "purist" Bill Bryson, "[m]itigate against often appears and is always wrong"10. How is it possible, according to Flesch, for something to be both common and an error? How common does an error in language use have to be before it no longer counts as an error? Does it have to be the majority of its uses? If so, we need research such as surveys or searches of language corpora* into the commonness of uses such as "mitigate against" before we can even know whether it's an error.

Over forty years after Flesch raised the white flag, "mitigate against" is still widely recognized as a grammatical error, and all but one of the books I cited above was published after Flesch's11. So, the "purists" are still militating against the barbarian hordes.

The Mystery of the Top Five

Every month, Victor Timm's Mystery Magazine conducts a survey of its readers to determine their most popular mystery writers. The list is ordered from one to five from favorite (1) to least liked (5). The same five writers, including Brand, made the list this month as last month, but each was in a different position. For instance, Christie rose in this month's rankings from last month. If you add together the digits of the positions from last month and this month, then the sum for Armstrong is seven, Christie's is eight, Doyle's is six, and Edwards' is five.

From the information above, can you determine the positions of the top five mystery writers for both months?

How to Lie With Notes 5: Death by Footnote1

The conspiracists work hard to give their written evidence the veneer of scholarship. The approach has been described as death by footnote2.

I take the title of this entry from the above passage from David Aaronovitch's book on conspiracy theories. Ironically and frustratingly, the second sentence is not noted, that is, there is no citation to a source, so there's no way to tell who described this "approach" as "death by footnote", which I would dearly like to know. Moreover, it's not as if the book has no notes―it has endnotes―so this is a ghost note of the second type, that is, a missing one3. Of course, Aaronovitch probably just couldn't remember where he heard or read the phrase, but he could have at least added a note explaining that.

In a magazine article published shortly before the book, and perhaps drawing on it, Aaronovitch wrote:

[Conspiracy theories] share certain features that make them work. These include…the use of apparently scholarly ways of laying out arguments (or "death by footnote")…. These characteristics help them to convince intelligent people of deeply unintelligent things.4

It's hard to tell from these two brief mentions what exactly Aaronovitch or his unnamed source meant by "death by footnote", though it's clear that it has something to do with conspiracy theorists (CTists) making a pretense to scholarship. There are many ways that pseudo-scholarship apes actual scholarship but, in this entry, I'll use the phrase "death by footnote" to refer to one particular practice, namely, loading up on notes. So, "death by footnote" is the opposite of ghost notes, that is, instead of too few notes there are too many.

Though Aaronovitch's topic in both the article and book is CTists, they're not the only guilty parties. For instance, the philosopher Roger Scruton describes a pseudo-philosophical book as follows: "Abundant footnotes, referring to out-of-the-way works in political theory, anthropology, biology, musicology, particle physics, etc., serve further to intimidate the reader, and the undergraduate, faced with the resulting text at the top of his reading list, is given no alternative but to parrot its terms….5"

While ghost notes and death by footnote seem mutually exclusive, they're not completely so. It's true that the first type of ghost notes―non-existent ones―are incompatible with excessive notes, since a work with no notes at all certainly can't have too many. However, the other type―missing notes, that is, notes that should be there but aren't―is compatible with an excess of notes. In fact, one way of concealing that a note is missing is to include so many other notes that it won't be noticed.

A good rule of thumb for scholarly works with notes is that the word count in the notes should never exceed that of the work itself. While such note bloat is not necessarily death by footnote, it's bad practice. If the notes are longer than the body of the work, then some of the material in the notes should either be incorporated into the text or made into a separate work. So, if you look at a page―assuming that you're looking at an old-fashioned paper book or journal article with footnotes―and more than half the page is taken up by notes, that's too many. However, death by footnote is not just a matter of having too many notes, but of using notes as a defense mechanism against criticism.

No Smoking in Pubic Places

"When I was only three, and still named Belle Miriam Silverman, I sang my first aria in pubic." Thus read the first sentence of the first printing of the first edition of an autobiographical work by the late opera singer, Beverly Sills1.

As I suspect you know, the word "pubic" refers to the part of the human body where the sexual organs are located2. "Pubic" is always an adjective, so the example sentence is ungrammatical, since the preposition "in" should be followed by a noun.

"Public" is both a noun and an adjective3. As a noun, it can refer to people as a whole, or the common people, as in the phrase "the public", or to those spaces that are open to the public, that is, places that are "in public". As an adjective, it modifies nouns that refer to public spaces, including physical places such as public parks as well as abstract spaces, such as public opinion.

Obviously, Sills meant that she sang in public. The typographical error was corrected in subsequent printings.

"In public" is not the only common phrase that may be transmogrified by a missing "l". A recent newspaper article displayed a photograph with the following caption: "Legislation to ban marijuana smoking and vaping in pubic places was approved by the Senate Regulated Industries Committee on Tuesday.4" I, too, approve of that legislation, though it reminds me of an old joke: "Do you smoke after sex?" "I don't know, I never looked."5

In addition to "pubic places", another frequent offender is "pubic library", which sounds as if it's a collection of pornography. A search of Google Books turns up a large number of occurrences of this phrase, surprisingly, from publications for professional librarians. For instance, an issue of The Library World includes a reference to the "Kettering Pubic Library"6. I suspect that library journals are more prone to this particular misspelling only because they more frequently refer to public libraries than other publications.

Most of the easily confused word pairs examined in these entries are soundalikes, but "pubic" and "public" are lookalikes. I doubt that anyone would ever mistakenly say "pubic" when "public" is meant, or vice versa, but when proofreading it may be easy to miss the difference. At a passing glance, the two words look the same, perhaps because the "l" in "public" is next to the "b" and each have a long upward stroke.

I've seen "pubic" in place of "public" on more than one occasion prior to stumbling over the above example, but I don't recall ever seeing "public" in place of "pubic", so this appears to be a one-way error. Of course, it's possible that this asymmetry is due to the fact that "public" is a more common word than "pubic". Also, some omissions of the "l" are pubescent puns, and others may be prurient pranks. Perhaps Sills was the victim of a proofreader with an adolescent sense of humor.

None of my reference books lists "pubic" as a common misspelling of "public", which could be because it's uncommon or perhaps just that the authors of such works are squeamish or prudish.

Spyhunters Vs. Spy

A spy has infiltrated the Agency for Counter-Terrorism (ACT). According to the agency's definition, a spy is someone who knows everyone in the agency by name but is known by name to no one else. An internal investigation by the agency's spyhunters has narrowed the suspects down to eight agents whom I will call only A through H to protect the seven innocent suspects.

The spyhunters interrogated the eight suspects in pairs, asking only whether they knew the other agent's name. While under interrogation, the agents were monitored by the most advanced deception-detection equipment available―equipment that is still classified as top secret―according to which each suspect interrogated told the truth.

Here are the answers elicited from the pairs of suspects when asked whether they knew each other's names:

A: "Yes"; B: "Yes".

C: "Yes"; D: "No".

E: "No"; F: "Yes".

G: "No"; H: "No".

Finally, after a short conference, the investigators called back into the interview room two of the agents, C and F, for further questioning. Asked if they knew each other's names, each replied:

C: "No"; F: "Yes".

Which suspect is the spy?

Extra Credit: Could there be more than one spy in the ACT? If not, why not?
