Maintaining Traditions of Practical Wisdom: Not Becoming a "Fool."

edited 091719
Practical wisdom is not musing about how someone else in a hypothetical situation ought to act. It's about "What am I to do?" -- right here and right now, with this person. A practically wise person doesn't merely speculate about what's proper; she does it.
-- Schwartz, B & Sharpe, K Practical Wisdom. The Right Way to Do the Right Thing. (2010) New York: (Penguin) Riverhead. p.7.
Ever noticed how many of the things we purchase come with assurances of "foolproof" usage? Why is that? Probably because, in order to save money, we purchase things that need assembly, or finishing of one kind or another, yet we are unlikely to have the familiarity with the objects involved to know how to avoid technical problems with them.

Those of us with a lot of schooling like to believe that having read abstruse texts and done difficult mathematics has somehow made us clever and handy when dealing with physical objects in the real world. Why waste money on completed items, or hire presumed "experts" -- likely a person with a few days instruction -- to assemble them for us, when we can do the job ourselves?

But just try, for the first time, to do any of the following:
a. digging a round hole one foot deep;
b. baking a soufflé ;
c. hammering a nail into a board;
d. assembling a small multicomputer network with peripherals.

We would do well to start off with some ancient wisdom: nothing is as easy as it looks. The few days' instruction that the kid at the hardware or electronics store gets is a few days more than we have. But, rather than take a few days to consider and prepare for what has to be done, we -- not wishing to "waste time" -- rush ahead and, if we are lucky, do a barely passable job.

If we break something, we put it back into the box and take it back to the store, telling them that "it came that way." The merchant, without objection, takes it back -- he has insurance (or warranty sales) covering such losses; and, a sale is a sale, the profit being substantial enough to cover several replacements -- for which they get credit from the manufacturer anyway. "Practical wisdom" often trumps even "honesty."

Social obligation can suppress personal virtue. Ruth Benedict in The Sword and the Chrysanthemum. (1946) Boston: Houghton, gives an example in the Japanese complaint, "I lost my virtue by fulfilling my obligations." This is offered as explaining why, in a "normal" movie plot shown to Japanese subjects of Benedict's research, a teacher shields his wealthy yet thieving mother from opprobrium, accepting the blame for the theft of school funds. This, in turn drives the teacher's wife, taking their young child with her, to commit suicide (and murder) rather than live with the familial shame. Filial piety, in some cultures, trumps many a personal consideration. (Consider the fatal feuding between the Hatfields and the McCoys. See also Honor Killing. Serving the Idols of the Tribe.)

"Modern" cycles of short-term use and replacement, "planned obsolescence," keep much of the economy going. But if fashion, alone, can't make you "upgrade," foolishness, e.g. mechanical ignorance, or deliberate planning, even, will. (Just think of mobile phones, "finished" and sold encased in slippery glass.)

But planned obsolescence or planned fragility works not only for mobile phones, DVD players, IKEA furniture, or automobiles or houses -- "fixer-uppers" -- , but also, increasingly, for medical care, law, scientific research and education. (See Schwartz & Sharpe, cited above, throughout.) Political and market, rather than disciplinary, considerations are at work to "fool-proof" the professions.

In education, unlike in other public service professions who know better than to wash their dirty laundry in public, there are always crusading "reformers" who are quite willing to point out who the fools are: thus we have recurrent attempts at "teacher-proofing" the curriculum. (See see On The Viability Of A Curriculum Leadership Role )

The success of this approach can be judged, for example, by the fact that, despite great hoopla and hype, Teach for America has yet to take over even small minority of public schools. It is the rare dilettante who has the patience, the dedication, to pursue expertise.

Even more painful for the greater majority of Americans to contemplate is, in these early days of the 21st Century, how dilettantism, not to mention rank incompetence has undermined vital functions of our national government.

But public service professionals, themselves, tend to shy away from rigorous resistance to the inroads made by those who would dilute professional norms and judgment for the sake of easy political and economic gain.

Hard Practical Questions? Handle Them or Dodge Them! Here's How. *

edited 4/24/21
If you can't solve a problem, then there is a easier problem that you can solve: find it.¨ -- George Polya, How to Solve It (cited in Kahnemann, p. 98)[1]

Don't go 'roun' flippin' cowpies! -- American Common Sense(?)


An often useful, cost-saving heuristic. Does watching violence on TV make kids more violent? The answers to this question, it appears, could have important practical consequences. But the question itself is problematic: it is highly ambiguous. And it risks generating time-consuming argument and more.

It used to be all-too-common, although somewhat bizarre, to observe even "professionally trained" people spending a lot of time and energy vehemently debating this question without taking the trouble to first determine whether they all understood the terms to mean the same (or similar) things.

Getting practical answers to vague questions can often be addressed by operationalization, that is, the specification of vague terms, e.g., "watching," "violence," by providing replicable, observable procedures for their determination.[2] The down side is that it might require expensive investigation to answer. All we might turn up, in any case, is a lot of dissensus, an impractical impasse!

Our original question about the effects of TV on children's propensities to violence generates even more problematic sub-questions:
1. What do you mean by "watching TV"? Need a child be paying close attention to it, or would just having it on in the background count? How do we determine how much TV a child is watching?

2. What counts as violence? Football? Mighty Mouse? A dramatization of an assault? Documentary footage from a war?"

3. How are we to determine if kids have become more or less violent? From their play-acting? From their actual fighting? From their arguments or threats?
In most situations, people would find this detailing process tedious. It distracts from the entertainment purposes of many a "debate," normally a sort-of quasi-intellectual arm wresting, or a contest in one-upmanship. Easy questions are usually thought to be "more interesting" than hard ones if only because they can be appreciated by a wider, "technically-challenged" audience (i.e. anybody having to weigh in on something beyond the reach of their experience).

So it is that even though the rituals of open discussion seem to satisfy our commitments to "democratic" participation, they muddy the flow of decision-making. Operationalization with its consequent query-reformulation process takes much more patience, with no guarantees of high-consensus outcomes to enable a push to the point of practical application.[2a]

Daniel Kahneman calls the reformulation of a query the Question-Substitution Heuristic. Developing heuristics often, if not always, involves operationalizing vague, general terms into something more specific and apprehendable without intricate processes. In his book, Thinking, Fast and Slow, Kahneman gives a chart of comparisons between what he calls Target Questions (hard) and Heuristic Questions (easy).[3]

Target Question Heuristic Question
How much would you contribute to save an endangered species? How much emotion do I feel when I think of dying dolphins?
How popular will the president be six months from now?How popular is the president right now?
This woman is running for the primary. How far will she go in politics? Does this woman look like a political winner?
Chart 1: Abridged from Kahneman (2011) pp. 98-99

Note that working out answers to the target questions, especially when money is involved, is often a laborious undertaking. By contrast, heuristic questions can be pretty much answered off the top of the head: they reduce the information-base for answering to what the questioning persons can easily access in memory. How likely this procedure is to provide good solutions to real problems one might judge by the example of participants of TV talk shows and no small number of our political and social pundits. (The accuracy of an expert, much less a pundit, in futurology tends to randomness. [3a])

But professional scientists, even, have been criticized for providing answers to questions they seem to have reformulated as easy.[4] Congressional response in 1958 to the question, "Why did the United States fail to beat the Russians into space?" was reformulated in the easier "who's-to-blame" mode, and ultimately responded to with the passage of the National Defense Education Act.[5]

The Theory-To-Practice Gap. An example. Public-supported institutions in our democratic society are often under severe pressure to widen participation, little matter whether those to be involved are even minimally informed or not. Consequently, questions that the most practiced and learned professionals might disagree on are usually decided by the least practiced and least knowledgeable of people.

What is mathematics, in its essence? Professional mathematicians can and do disagree. Likewise professional historians, on history. And professional political scientists, on political science. But, for example, educational institutions or systems, have (often elected) local governing boards, who must act to distribute (often, partially) tax-funded budgets. These governors, often with minimal knowledge, if any, about subject matter content, resource-needs and age-appropriate teachability, tend to decide all such questions as matters of budget. Consequently, matters of mathematics and history course contents become fodder for political brewhahas!

The operative heuristic for cost-chary governing boards dealing with broad, general questions is an interrogatory[6] that looks somewhat like this:
a. Are there any foreseeable, imminent and severe repercussions to our ignoring this question? If not, "table" it.

b. Is there any demand for any of these subject matters from Influential Constituencies (ICs) ? If not, "table" it.

c. What costs would different programs, say, of mathematics education, entail, were we to decide to implement one of them in the schools? Get those estimates. (Don’t rush. "Table" it.)

d. Will our ICs likely support us in our decisions? If not, "table" it.

Lets mimic Kahneman’s chart 1. The target question group, in the left column, will contain the kinds of questions encountered, for example in educational governors' meetings (or, even, in casual public discussions). In the right column well put the heuristic questions, the kinds of questions likely to be substituted by governing boards' committees.

Target Question Heuristic Question
What are the aims of our institution's educational programs? How can we use our institution to satisfy the demands of different community and political constituent groups?
Should beginning (pre-college or undergraduate) students be required to take introductory classes of a general nature? Can we make room in the budget for such new courses without threatening the sacred cows of
influential people?
Should all K-12 students be prepared to go to college? Who can we overlook without raising a din that threatens our tenure as governors?
Chart 2
From Chart 2 and the preceding interrogatory we can see why, despite much lip-service to the contrary, academic programs will likely continue to be kept in distant second place by educational decision makers in comparison to their personal or political concerns. With a bit of adjustment the processes shown in Chart 2 can be adjusted to many different kinds of institutions and the problems they are faced with.

Why Is It Wise to Consider Using the Substitution Heuristic? The heuristic can be useful for transforming idealistic, but vague claims into something that can be tested for implementation, but ... nonetheless, it's use is somewhat of a distraction from the original hard problem. In fact it may lead quite far from the original problem if cleverly transformed by sloganeering supported by enthusiastic promotion. For example, instead of dealing with the difficulties of admitting underprepared students to higher education, we focus on "expanding" opportunities by reducing entrance requirements. This may address the issue of underfilled classrooms, but exacerbates the problem of second- or third-year dropouts.

The drop-out problems might, in turn, be addressed by giving credit for "experience" or watered-down course work so as to satisfy public perceptions of equity in admissions, instead of funding pre-admission courses in remedial training for academic demands.

A decision-maker ought to learn and retain the Substitution-Heuristic for unforeseen necessities. Why is that? It's because honesty is not always the best policy if one wants to keep one's position or reputation in one's institution. Inverse correlations between celebrated "high expections" demanded and resources available are not uncommon. Just as a stupid question is said to merit a like answer, so does a complex and difficult problem, masqueraded as a simple, "common-sense" inquiry merit calling up an intricate process of analysis, starting with the temporizing of the Substitution Heuristic. Why? Ultimately, for the sake of one's rationality and personal mental-emotional health.

Lecture: an overused pedagogical tool?

Any subject can be made interesting, and therefore any subject can be made boring. -- Hilaire Belloc
Why do teachers at all levels lecture so much? First of all, lecture is a cheap "delivery method." Class size can be maximized once lecturer-student interaction is dispensed with. Lecture is not, however, an effective means of developing and tracking knowledge or skills in a great many people.

Second, lecture is the easiest technique for the teacher to develop a modicum of skill at. It requires minimal preparation. (A fast talker can "wing it" from time to time apparently undetected by his audience.)

Third, and not the least important, the emphasis on lecture obscures the common perception that pedagogical skill is inversely related to level taught; that is, elementary and middle school teachers tend to be better at pedagogy than high school teachers and college professors. (Many universities go through an elaborate ritual of denial by bestowing MacArthur awards for teaching on – usually, assistant -- professors whom they later reject for tenure.)

Mental Meringue: conjecture as educational theory

edited 5/21/20

Two groups (among others) abet the destruction of our public schools as educational systems: boards of education and professional educators .

Board members -- pursuing megalomaniac visions and frequently not understanding what it takes to run a real school with real warm bodies in it -- are too often ready to sell out to any political interest that assures them continuity of office.

Professional educators -- through their formal and in-service education -- have been so stuffed with flatulent conjecture, minimally substantiated, often contradictory, sketches of theory, mental fluff that passes for science, that they cannot deal effectively with simple organizational and classroom problems.

Undisciplined conjecture, expanded through leaps of logic and magnified by fear or fervent hope generates the bulk of topics of discussion not only in Education, but also in the world at large.

Public schools, especially, are vulnerable to political meddling, to intrusions by ideologues of all kinds, for whom conjecture is a way of life, so long as others bear its consequences.
