Another Monday

Monday, 15 April 2019

Another Monday has effectively passed without my receiving a rejection from the latest journal to which I offered my paper on probability.

My paper was submitted to that journal on 20 February, and on 2 March I was informed that it were assigned to a handling editor and that I'd be notified when a report were returned by a reviewer. I don't know whether a reviewer has accepted the assignment; but, while sometimes it takes months to find a reviewer, usually that happens more quickly. The journal says that it makes an effort to make a decision within three months; but, at most journals, reviewers are asked to return a report in something like four weeks or a month. So, while the three-month mark is six weeks away, it is increasingly plausible that a decision will be made soon.

Those who review academic articles and edit academic journals do so as a side activity, and are most likely to give time to this activity on the weekends. Additionally, weekends are psychologically natural for self-imposed deadlines. Monday becomes the most probable day for an editor to inform an author of a decision. Because the journal and the handling editor are in Europe, Monday effectively ends in what is for me the late after-noon.

And the most likely decision is a rejection. I don't think that I quite said this when previously writing about submitting my article to a journal. Instead, I wrote about the fate of most articles being rejection. But, after observing the responses of reviewers at those previous journals, I've reached a judgment about probability. It's probable that my article will again be rejected.

Thus, on each Monday, I look for a rejection.

Blinded by the Light

Sometimes, people who have trouble understanding an expression that is complete, unambiguous, and concise will claim that the expression is unclear. This response is very much like claiming that a day upon which they want sunglasses is foggy.

Submitted Anew

Thursday, 21 February 2019

On 20 February, I submitted my paper on probability to yet another academic journal. To my surprise, the journal in question gave me a choice as to whether my review would be doubly blind — with my identity withheld from the reviewers; I chose that option.

Although in my initial reading of the longer of the two reviews that I most recently received I found no worthwhile criticism, I thought that I should pore over that review carefully, to ensure that I didn't overlook anything in it that would cause me to improve my paper. However, though the review was not written with abusive intent, it is none-the-less abusive, and I was averse to reading it. To impel myself to read it carefully, I decided to write a response to each of the criticisms within it, as I would then have to take care to find and to consider each criticism. I completed a draft of the response without finding any good reason to revise my paper. Having gone that far with the draft, I proofread it on 21 February, and posted a version on-line. It is written more in the manner of a 'blog entry than of something intended to go into a journal or book; and I don't know that any of you would want to bother with reading it in any case. But it's available.

Between the time that I previously submitted the paper and the time that received the most recent decision, I more efficiently organized the citations in one paragraph and I compressed one appendix by removing formula numbers and by suppressing logical quantifiers so that its eleven formulæ could be placed into a one-page grid.

Up-Date (2018:03/02):

In the early morning of 2 March, I received e.mail indicating that my probability paper had been assigned to a handling editor (who was named), and that I would be contacted after a reviewer had returned a report. It seems that the threat of a desk rejection has passed. I made a very cursory check on the handling editor; she seems quite qualified.

Sowing Pseudo-Scientific Seeds of Racism

Thursday, 2 August 2018

I have previously expressed great concern about journalists confusing the categorization of a people as H. sapiens with their being human. Bodies Keep Shrinking on this Island, and Scientists Aren't Sure Why, a story in the New York Times, offers yet another illustration of this confusion. Within it, Carl Zimmer writes:

The researchers found that a very small percentage of the villagers' DNA came from Neanderthals or Denisovans. A tiny portion could not be matched to humans, Neanderthals or Denisovans.

But these enigmatic pieces weren’t dramatically different from human DNA, as you’d expect if they had come from Homo floresiensis. Dr. Tucci concluded that the Rampasasa villagers have no Homo floresiensis ancestry.

Note that, once again, Neanderthals and Denisovans are distinguished by a journalist from humans, as are now those of H. floresiensis. No reason is given for classifying any of these people as not human; the journalist has simply inferred that they are not because they have been classified as of a different species; what that classification actually means is utterly unconsidered.

Further, in the article, modern populations are noted to have differing occurrences of presence of DNA from the supposedly inhuman populations — not dramatically inhuman, but supposedly inhuman none-the-less.

Let me make it very plain: Mr Zimmer and the New York Times are offering pseudo-science with racist implications. He probably doesn't intend those implications, but is simply thoughtless. However, his thoughtlessness and that of his editors are inexcusable. And, if he had any conversations with the scientists who conducted these studies, then I'd like to know why the Hell they failed to impress upon him that the taxonomy did not separate people into humans and non-humans. These scientists did not have the prerogative of unscientifically presuming that Mr Zimmer had more intelligence than has been actually demonstrated by the typical journalist.

Into the Twelfth Week

Saturday, 12 May 2018

The reported status of my probability paper has remained Editor Assigned for more that eleven weeks now. I have sent a message to the Journals Editorial Office, requesting precise information on the actual status of the paper.


The reply that I received from the Journals Editorial Office was that the editor had my manuscript and I would be informed of a decision after it had been reviewed. I responded that this were not a proper answer, and explained that I would not be so patient as I had been when a Springer journal had been slow and uncommunicative about a previous paper.

If I do not receive a proper answer by Tuesday morning and the reported status remains unchanged, then I will attempt to write directly to the editor. Right now, there seems a substantially greater probability that I will soon inform the journal that my paper is no longer available for their consideration.

Up-Date (2018:05/14):

I received a more informative answer from the Journals Editorial Office early this morning. They reported that the paper were still being evaluated by the editor, and that the search for reviewers had not been begun.

It is disgraceful if the editor truly hasn't completed his own evaluation after the passage of so much time. Editors have many papers at which to look, but still it is the norm for them to have evaluated any given paper within one month. My paper is challenging, but not so challenging as to justify taking more than twice the standard amount of time.

I am trying to decided when to withdraw the paper from their consideration if I have not been told that reviewers are assigned or at least that a search for reviewers is underway. I do not think that there is any constructive use in issuing an ultimatum; that would almost surely result in a quick rejection. So I think that I need simply to decide for myself at what point to contact them and tell them that the paper is no longer available to them.

It has famously been argued that the word game cannot be defined in a way that adequately captures the various senses in which it is used. I believe that, in everyday use, the term game most often means a system of contrived challenges properly imposed or undertaken for purposes of amusement. Hence, someone might assert something such as Love is not a game! But, even in lay-use, game can have other meanings. For example, when a person proceeds deceitfully or insincerely, he or she may be said to be making a game of things, without necessarily seeking amusement in proceeding in this way.

Economists and mathematicians applying themselves to problems of economics or proximate to those of economics can use the term so very broadly as to refer to any problem of optimization. But, most often, they mean a system in which multiple parties interact with the potential for one or more parties to advance an interest or something that is treated as an interest (such as reproduction). It is in this sense that I here use the term game.

The rules of games are often subject to to change, and those changes may be affected or effected by players of the governed game. There is thus a meta-game — a system in which multiple parties interact with the potential for one or more of them to advance an interest by changing the rules of the game; or, in the context of others trying to changing the rules, by preserving the rules. The concept of meta-games is hugely important for understanding social processes.

Of course, a meta-game might have its own meta-game — a meta-meta-game. For example, the determination of a legal frame-work might be the meta-game of the social processes that the frame-work governs, and a struggle over social values might be the meta-game of the determination of the frame-work and thus the meta-meta-game of those social processes. But it can be difficult — without necessarily being useful — to work-out an actual hierarchy.

Sometimes, all that we really need to recognize is that some activity is a meta-game of some other game, without concerning ourselves as to whether the other game is itself a meta-game. People might readily recognize meta-gaming in activities such as political lobbying, but they generally don't recognize it when it's effected by psychologists, by teachers, or by screen-writers.

I want to draw upon this notion of meta-games for at least one 'blog entry, but I will probably want to draw upon it for multiple entries, so I will leave this entry as infrastructure. And I may later and without notice rework it, in an attempt to improve it as infrastructure.

Vocal Cues

Monday, 26 June 2017

Many animals, across different classes, have two distinct sounds that may be classified as growls or as whines, respectively. The growls signal threat; the whines signal friendship or appeasement.

The bark of a dog is actually a combination of a growl with a whine; it is thus not a pure signal of aggression, as many take it to be; it is literally a mixed signal, perhaps indicating confusion on the part of the dog, perhaps signalling both that the dog is prepared to fight and that the dog would consider a peaceful interaction.

When women talk with men whom they find attractive, women tend to raise the pitches of their voices. Men tend to do something different when talking with women whom they find attractive; they mix deeper tones than they would normally use with higher tones than they would normally use. The deep tones are signals of masculinity, of being able to do what men are expected to do. The higher tones of men carry much the same significance as do the higher tones of women — with the additional point in contrast to the deep tones that the man does not mean to threaten the woman.

It amused me to reälize consciously that this behavior by men is at least something like barking. Then I grimly considered that some men are actually barking, telling the woman that he can be nice to her if she is nice to him, but will actively make things unpleasant if she is not. But at least it should typically be possible to disambiguate the threatening behavior, based upon where the low notes are used, and of course the choice of words.

On the Meaning of Sexism

Thursday, 11 May 2017

In a previous entry, I noted that the original definition of racism was a theory or an adherence to a theory that merit is in part intrinsically a function of race. It was exactly by analogy with the word racism that the word sexism was introduced in 1968, thus referring to a theory or an adherence to a theory that merit is in part intrinsically a function of sex.

Now, here is where matters get tricky. In any case in which one rejects sexism, it is regarded as an inappropriate response to the sex of people; and, in particular, the treatment is likely to be seen as unethical. A very great many folk employ the concept of unethical response to the sex of people as if that were the very definition of sexism. That notion is going to operationalize very much like the actual definition whenever and wherever the issue at hand is one of ethics and ethics actually call for neutrality — for a rejection of the relevance of sex to the issue. But nearly all of us regard people of one sex as better suited to some rôles that are of importance. For example, if I presume that sexism must refer to something unethical, then I am compelled either to associate sexism with something other than neutrality of a sort, or as a matter of justice to try to entertain thoughts of accepting a man as a potential spouse for myself. (People are led astray by the analogy with racism; the cases in which sex is relevant to selection loom larger because of the importance of reproduction.) And the substituted notion is not going to operationalize at all like the original definition exactly when someone believes that merit is a function of sex in a far wider range of cases than do folk such as I; then the substitution is going to get things almost perfectly twisted around. He or she will label anti-sexism as sexism and will label some sort of sexism — perhaps quite an intense sexism — as anti-sexism.

The spurning of a claim of relevance is the maintenance or adoption of indifference. This indifference is an equality of one sort — and we often see the words equal and equality used in antonymy to sexism — but it is not an equality of various other sorts. Advancement of a conflicting equality would itself be sexist. Such conflicting equalities can arise when the equality sought is equality of outcome. If people, regardless of sex, may be presumed to respond to a framework in essentially identical ways, and we observe markèdly different outcomes for one sex compared to those for another, then this difference is prima facie evidence that the framework is sexist. But if it is recognized that people of one sex behave differently in that framework, then the presumption that the framework is sexist does not follow from the mere presence of a difference. If we say that the different behaviors must be treated as of equal merit because otherwise a difference in outcomes emerges, then the merit that is ascribed to the behavior is treated as a function of the sex of the people who engage in that behavior; that prescription is itself intrinsically sexist.

For example, the rates at which men are arrested for, charged with, and convicted of criminal behavior of various sorts are much higher than the corresponding rates at which women are arrested, charged, and convicted. We cannot conclude simply from these differences that the system of criminal law is sexist, because it may be that men simply engage in that behavior more often; indeed, most of us are fairly sure that this latter case holds. If we insist that the behaviors themselves must be decriminalized in order to reduce the rates at which men are arrested, charged, and convicted, then we are inferring the relative merit of the behavior from the sexes of those who engage in it. The very same sort of analysis would apply to hiring practices and to the wages or salaries paid to those in various occupations.[1]

(Many people, including certainly me, would argue that an unfortunate sexism prior to whatever exists in the legal system is one factor contributing to greater criminality by men, but few-if-any people propose that part of an appropriate response would be an adjustive sexism, giving more tolerance to male criminalized behavior than to female criminalized behavior. Likewise, some of us assert that an unfortunate sexism prior to whatever exists in the jobs market is one factor leading to different career outcomes for women, but we don't propose an adjustive sexism attempting to compel employers to pay women more than the expected values of their marginal products.)

The confused presumptions that only an unethical discrimination can count as sexism and that sexism is found where there is some sort of inequality other than non-neutralityan attention to sex — causes people in all sincerity to misapply the word sexism and to fail to see legitimate application of the word, perhaps to their own attitudes and actions. If substitutions of these sorts are not recognized by those who use the word sexism in accordance with its definition, then interactions will be characterized by mutual incomprehension, quite possibly enraged. Attempts to employ logic and facts won't be persuasive because one of the two groups will actively misunderstand a word central to any communication. Additionally, there are people who implicitly believe that ethical significance clings to symbols, such that by changing labels what was wrong may be made to be right and vice versa. In dealing with them, the principal point that ought to be made is not that words cannot be redefined, but that, if we should for any reason redefine sexism, then whatever case was made against what was originally called sexism isn't thereby logomantically transformed into a case against whatever is now to be called sexism, nor is a case against something that was originally called sexism somehow invalidated by ceasing to call it by that name.[2] Of course, there are also those who effect the substitution as a device of unconscious projection, and others who opportunistically seek to sow further confusion.

[1] In the absence of a coherent explanation otherwise, if any population really could be hired at bargain rates, then not only should we expect all members of that population to be hired before any members of any other population; we should expect employers to bid-up the wages and salaries of this less expensive population to the point that they matched those of other populations, before hiring any members of those other populations. If there is some occupation such that the cost of hiring workers for it is notably less than the expected values of their marginal products, then we should expect employers to increase their hirings for those occupations, and in doing so (each in competition with the others and in the face of otherwise ever more reluctant workers) to bid-up the wages or salaries of those workers until the difference disappears.

[2] The same principle of course applies to efforts to redefine racism.

λέγει αὐτῷ ὁ Πιλᾶτος τί ἐστιν ἀλήθεια;

Wednesday, 25 January 2017

Years ago, National Lampoon had a monthly column that they entitled True Facts. The title was a joke, not because the contents weren't true (they were an assembly of extraödinary news reports), but because facts cannot be untrue; something untrue is not a fact. Yet many people in various contexts were using terms such as actual fact, real fact, and true fact, almost as if it were possible for some facts to be false, imaginary, unreal. People still do, perhaps even more often. One can find lots of instances of people using imaginary fact; sometimes they do so ironically, but more often they are quite serious. By imaginary fact they mean a proposition that may be untrue, is likely to be untrue, or simply is untrue. In this retasking of the word fact, they've lost the use of the word to talk about facts, unless they add a word such as true. But, with that change in meaning, it not only becomes possible to use a term such as alternative fact to refer to a rival claim, but it becomes harder to see that untrue rival claims don't have equal standing with true rival claims, as they are all supposedly facts.

We aren't at all helped here that a great many people don't understand the words true and truth. That's not simply a problem of vocabulary. Truth is a hard concept, because it entails a meta-propositional act of mapping from a proposition back to itself. That is to say that, in most cases when we apply the word true or equivalent and certainly in the case of true facts, we are explicitly or implicitly making a proposition about a proposition. When we say It's true that I went to the store, that actual referent of the grammatic subject is not I, but the proposition that I went to the store, yet the upshot of this sentence is merely what would be conveyed in saying I went to the store. We perhaps don't need this device of recasting a proposition (I went to the store) as a meta-proposition (It is true that I went to the store), but it is useful because we are not omniscient, and must entertain propositions that are uncertain or discovered to be false; the concept of truth complements the conditions of falsehood and of uncertainty. Yet it is very hard to see that function, exactly because we use the concept to discuss itself. Truth is more easily named than described, if indeed a description is possible.

The difficulty in understanding the nature of truth makes it psychologically easier to embrace such notions as that all aspects of of past, present, and future are simply artefacts of individual belief or of group belief (expressed with formulæ such as truth is a social construct) or that what one wants or ought to want is to be treated a true. The word fact may then be used for components of narratives; embracing one narrative is seen as licensing one to accept propositions as fact that are alternative to components of rival narratives, and to reject propositions for no better reason than that they participate in rival narratives. Evolution of narratives is seen as licensing one to change the status of a proposition from fact to falsehood, or vice versa, even when discussing history. And we may even observe those socially identified as fact-checkers testing claims against narratives which are themselves never fact-checked, because the checkers implictly treat their favored narratives as the ultimate determinant of fact.

When Pilate asked What is truth?, perhaps he was truly curious as to the nature of truth, but he may merely have been asking why he should give a damn about it. Our political leaders have become ever more disdainful of truth. They have long offered us alternative facts, and their followers in each of our major political tribes and in most of the smaller groups as well have decided that, for them, these are the facts. Now we have an Administration that does so more baldly and less artfully. One might hope that this practice will explode on them; but, even if that explosion should happen, their opponents are likely to see an expansion of the envelope within which they may disregard the facts.


Saturday, 7 January 2017

Elsewhere, Pierre Lemieux asked In two sentences, what do you think of the Monty Hall paradox? Unless I construct sentences loaded with conjunctions (which would seem to violate the spirit of the request), an answer in just two sentences will be unsatisfactory (though I provided one). Here in my 'blog, I'll write at greater length.

The first appearance in print of what's called the Monty Hall Problem seems to have been in a letter by Steve Selvin to The American Statistician v29 (1975) #1. The problem resembles those with which Monty Hall used to present contestants on Let's Make a Deal, though Hall has asserted that no problem quite like it were presented on that show. The most popular statement of the Monty Hall Problem came in a letter by Craig Whitaker to the Ask Marilyn column of Parade:

Suppose you're on a game show, and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what's behind the doors, opens another door, say No. 3, which has a goat. He then says to you, Do you want to pick door No. 2? Is it to your advantage to switch your choice?

(Before we continue, take car and goat to stand, respectively, for something that you want and something that you don't want, regardless of your actual feelings about cars and about goats.)

There has been considerable controversy about the proper answer, but the text-book answer is that, indeed, one should switch choices. The argument is that, initially, one has a 1/3 probability that the chosen Door has the car, and a 2/3 probability that the car is behind one of the other two Doors. When the host opens one of the other two Doors, the probability remains that the car is behind one of the unchosen Doors, but has gone to 0 for the opened Door, which is to say that the probability is now 2/3 that the car is behind the unchosen, unopened Door.

My first issue with the text-book answer is with its assignment of initial, quantified probabilities. I cannot even see a basis for qualitative probabilities here; which is to say that I don't see a proper reason for thinking either that the probability of the car being behind a given Door is equal to that for any other Door or that the probability of the car being behind some one Door is greater than that of any other Door. As far as I'm concerned, there is no ordering at all.

The belief that there must be an ordering usually follows upon the even bolder presumption that there must be a quantification. Because quantification has proven to be extremely successful in a great many applications, some people make the inference that it can be successfully applied to any and every question. Others, a bit less rash, take the position that it can be applied everywhere except where it is clearly shown not to be applicable. But even the less rash dogma violates Ockham's razor. Some believe that they have a direct apprehension of such quantification. However, for most of human history, if people thought that they had such literal intuitions then they were silent about it; a quantified notion of probability did not begin to take hold until the second half of the Seventeenth Century. And appeals to the authority of one's intuition should carry little if any weight.

Various thinkers have adopted what is sometimes called the principle of indifference or the principle of insufficient reason to argue that, in the absence of any evidence to the contrary, each of n collectively exhaustive and mutually exclusive possibilities must be assigned equal likelihood. But our division of possibilities into n cases, rather than some other number of cases, is an artefact of taxonomy. Perhaps one or more of the Doors is red and the remainder blue; our first division could then be between two possibilities, so that (under the principle of indifference) one Door would have an initial probability of 1/2 and each of the other two would have a probability of 1/4.

Other persons will propose that we have watched the game played many times, and observed that a car has with very nearly equal frequency appeared behind each of the three Doors. But, while that information might be helpful were we to play many times, I'm not aware of any real justification for treating frequencies as decision-theoretic weights in application to isolated events. You won't be on Monty's show to-morrow.

Indeed, if a guest player truly thought that the Doors initially represented equal expectations, then that player would be unable to choose amongst them, or even to delegate the choice (as the delegation has an expectation equal to that of each Door); indifference is a strange, limiting case. However, indecision — the aforementioned lack of ordering — allows the guest player to delegate the decision. So, either the Door was picked for the guest player (rather than by the guest player), or the guest player associated the chosen Door with a greater probability than either unchosen Door. That point might seem a mere quibble, but declaring that the guest player picked the Door is part of a rhetorical structure that surreptitiously and fallaciously commits the guest player to a positive judgment of prior probability. If there is no case for such commitment, then the paradox collapses.

Well, okay now, let's just beg the question, and say not only that you were assigned Door Number 1, but that for some mysterious reason you know that there is an equal probability of the car being behind each of the Doors. The host then opens Door Number 3, and there's a goat. The problem as stated does not explain why the host opened Door Number 3. The classical statement of the problem does not tell the reader what rule is being used by the host; the presentation tells us that the host knows what's behind the doors, but says nothing about whether or how he uses that knowledge. Hypothetically, he might always open a Door with a goat, or he might use some other rule, so that there were a possibility that he would open the Door with a car, leaving the guest player to select between two concealed goats.

Nowhere in the statement of the problem are we told that you are the sole guest player. Something seems to go very wrong with the text-book answer if you are not. Imagine that there are many guest players, and that outcomes are duplicated in cases in which more than one guest player selects or is otherwise assigned the same Door. The host opens Door Number 3, and each of the guest players who were assigned that Door trudges away with a goat. As with the scenario in which only one guest player is imagined, more than one rule may govern this choice made by the host. Now, each guest player who was assigned Door Number 1 is permitted to change his or her assignment to Door Number 2, and each guest player who was assigned Door Number 2 is allowed to change his or her assignment to Door Number 1. (Some of you might recall that I proposed a scenario essentially of this sort in a 'blog entry for 1 April 2009.) Their situations appear to be symmetrical, such that if one set of guest players should switch then so should the other; yet if one Door is the better choice for one group then it seems that it ought also to be the better for the other group.

The resolution is in understanding that the text-book solution silently assumed that the host were following a particular rule of selection, and that this rule were known to the guest player, whose up-dating of probabilities thus could be informed by that knowledge. But, in order for the text-book solution to be correct, all players must be targeted in the same manner by the response of the host. When there is only one guest player, it is possible for the host to observe rules that respond to all guest players in ways that are not not possible when there are multiple guest players, unless they are somehow all assigned the same Door. It isn't even possible to do this for two sets of players each assigned different Doors.

Given the typical presentation of the problem, the typical statement of ostensible solution is wrong; it doesn't solve the problem that was given, and doesn't identify the problem that was actually solved.
