Believing Untrue Things

More Motives on Untrue Things

Summary: People believe in the truth of ideas that don’t withstand even casual empirical scrutiny, e.g., that American police kill more black people than white people every year. Why do so many of us believe in and even defend vehemently the validity of bogus ideas when contrary evidence is easily found?

You can find many examples of this kind of thing in Amazon reviews of controversial books such as Democracy in Chains by Nancy MacLean:

5-Star Reviews

1-Star Reviews

The respective authors of the five-star and one-star reviews appear to inhabit separate factual universes. In one universe James Buchanan was a distinguished laissez-faire economist and originator of public-choice theory. In the other universe Buchanan, the Koch brothers and other prominent libertarians were members of a racist conspiracy. How can people on one side of a controversy remain ignorant about the other side’s arguments and even basic facts?

AVI suggests possible explanations that are worth reading, as always. I think the main problem is the poor quality of our primary and secondary educational systems, particularly in the teaching of history, math and basic statistics. Another big problem is the ignorance of journalists who were educated in our lousy schools, and modern journalism’s clickbait business model that incentivizes the promotion of controversy and conflict even more than was the case back in Front Page days.

Reopening — II (Theory)

by

That’s all very well in practice, but how does it work in theory?

— old University of Chicago joke

I expect this blog’s readership to demand the theoretical considerations, so here’s a (non-exhaustive) compilation, beginning with a setup anecdote:

In December of 2007 I was briefly—very briefly, as the work was interrupted by a blizzard—involved in rebuilding in Greensburg, Kansas, which had been practically erased from the map seven months earlier by an immense tornado. I had driven through a couple of months after the event and stumbled into a photo-op for Sen. Pat Roberts, who was doing a ribbon-cutting of sorts in a brand new convenience store. The devastation was more impressive than his speech; indeed, people who worked both New Orleans after Katrina and Greensburg after the tornado typically remarked that, allowing for scale, Greensburg was worse.

SARS-CoV2/COVID-19 Update, Easter 2020 edition

by

There are lots of hopeful reports — despite the USA COVID-19 infections being over 1/2 million and the total deaths of over 20,000 people — that the pandemic will soon be “Over.”

This is fantasy thinking at best.   SARS-CoV2/COVID-19  won’t be over, until it is over, for YEARS.

“Over” being defined as world wide mass vaccinations to the tune of 70% of humanity or human herd immunity.   Assuming such a thing is possible, which it may not be, given this recent report from the UK Daily Mail on post SARS-CoV2/COVID-19 infection immunity —

Blow to Britain’s hopes for coronavirus antibody testing as study finds a THIRD of recovered patients have barely-detectable evidence they have had the virus already

.

– Nearly third of patients have very low levels of antibodies, Chinese study found
– Antibodies not detected at all in 10 people, raising fears they could be reinfected
– Explains why UK Government repeatedly delayed rolling them out to the public

Or this  South Korean story on coronavirus “reactivation” —

South Korea reports recovered coronavirus patients testing positive again
APRIL 10, 2020

The issue with most COVID-19 tests, like the ones mentioned in South Korea, is they detect SARS-CoV2 RNA. They do not detect whether the viral particles are active or not. The issue here is whether these people are shedding active viral particles that can re-infect people.    We don’t know if that is the case here from the story text.   Given how infectious it is.   This coronavirus will tell us in due course.

There are some viral diseases like Herpes that hide inside your body and reactivate to make you infectious. We do not know enough about the SARs-CoV2 virus to say whether that is the case here.

If the SARS-CoV2 virus is like Herpes in that once contracted, it never goes away and flares infectious several times a year.

And there is no herd immunity for some people no matter how often they are infected.

Then we will need multiple, cheap,   out-patient style “cure-treatments” as well as multiple vaccines, based on co-morbidities, and possibly to account for racial differences like sickle cell blood mutations, as SARS-CoV2 may well be more a blood disease than a respiratory infection in terms of it’s killing mechanism.

There is not enough reliable data, d*mn it!

Until we get to “Over,” our old economic world of Just-In-Time, Sole Source anywhere, but especially in China, is dead without replacement.

The world is in the same position as Germany was from August 1944 – April 1945 or   Japan from August 1944 until August 1945 versus the Allied strategic bombing campaign.   We have entered the world of   “End Run Production“ as world wide supply chains grind to a halt from various fiddly bits of intermediate parts running out without replacement.   The on-and-off hotspots world wide of COVID-19 at different times and places in the world economy is no different than WW2 strategic bombing in terms of causing random damage to the economic life support.

See also   “End Run Production” here from this one volume WW2 history book The Great Crusade:

https://books.google.com/books?id=5L-bwPZK7PQC&pg=PA420&lpg=PA420&dq=%22End+Run+Production%22&source=bl&ots=kc30FQflCj&sig=ACfU3U2kmF-kTPo0Tgr2A9_ESPKpEQAEOg&hl=en&sa=X&ved=2ahUKEwjfpurOnOPoAhUKA6wKHemwBMcQ6AEwAHoECC4QKQ#v=onepage&q=%22End%20Run%20Production%22&f=false

Be it automobiles, self propelled construction equipment, jets, power plants or the latest electronic gadget, anything that has thousands of parts sourced world wide with lots of Chinese cheap/disposable sub-component content anywhere in the supply chain simply won’t be produced for the next 18 months to three years.

This “random damage to the economic life support” effect is amplified by the unwillingness of Western private industry to invest in building the capitol equipment to produced those intermediate parts.   Because of the threat of China coming back with predatory pricing — using bought politicians to cover for them — means those parts won’t be built without massive cost plus contract government buy out of the investment risk like happened in the USA in the 1942 WW2 mobilization.

The story of   one American n95 mask manufacturer’s experience with the Obama Administration in 2009 with the Swine flu is a case in point.   The n95 mask is a 50 cent item where China pays 2 cents a mask for labor versus 10 cents a mask for American labor.   When the American manufacturer geared up to replace Chinese mask production.   China came back on-line and the Obama Administration refused to keep buying the American mask producer’s 8 cents more expensive mask when the Chinese masks were available.

Unlike almost 80 years ago, current Western and particularly American politicians are too corrupt to go too massive cost plus contract government buy out this private investment risk.   Mainly because these political elites   can’t be bothered to figure out their 10% cut.   Instead we are getting more “fiscal stimulus” AKA boondoggles that the elites will saddle the rest of us with high interest payments on huge public debts.

It will take local small to mid-sized business to get the American economy going during the COVID-19 pandemic via making products and services that don’t use the intermediate products China threatens with when the pandemic ends.

My read on what comes next economically is local/distributed production with limited capitol investment that is multi-product capable.   The name for that is additive manufacturing, AKA 3D Printing. Here are a couple of examples:

  1. The idea of 3D  Printed Sand Casting Molds For Automobile Production

voxeljet enters alliance to industrialize core tooling production using 3D printing

2. And the replacement of physical inventory with 3D printers, print media and electronic drawings:
Such “Make or buy” decisions have always been the key decision of any business.   The issue here is that middle men wholesalers and in-house warehousing holding cheap Chinese-sourced   intermediate parts are both set to go the way of the Doe-Doe Bird in a 3D/AM manufacturing dominated world.
.
Distributed production in multiple localities with 3D/AM vendors for limited runs of existing intermediate products to keep production lines going.   Or the re-engineering intermediate products so one 3D/AM print replaces multiple intermediate products for the same reason, will be the stuff of future Masters of Business Administration (MBA) papers describing this imminent change over.

.

But, like developing SARS-CoV2/COVID-19 vaccines, this new locally distributed manufacturing economy will take time.   The possible opening of the American economy in May 2020 will not bring the old economy of December 2019 back.

.

That economy is dead.   It cannot, will not, come back.

.

We will have to dance with both the sickness from SARS-CoV2/COVID-19 and the widening “End Run Production“ product shortages that the death of the globalist   just-in-time, sole source in China economic model causes for years.

.

And this is a hard reality, not a fantasy, we must all face.

What I’ve got so far:

  1. Everything’s on the table. The likelihood that your preexisting ideology or priorities are an entirely adequate match to what this situation truly requires of us is close to nil. “In a time of drastic change it is the learners who inherit the future. The learned usually find themselves equipped to live in a world that no longer exists.” ”• Eric Hoffer
  2. That said, your life experience will give you insights. Privilege your experience over your ideology and nominal priorities.
  3. All disasters are local. Concentrate on your meaningfully immediate environment, which in this case will be the local market for medical resources. For most of the US, that will be our MSA. For those outside an MSA (metropolitan or micropolitan) that will be their county; and for some it will be the group of counties that feed into the one hospital in the region.
  4. Deprioritize pandemic news from outside your local area. There are people in the massive NY/NJ/MA outbreak that I worry about, but what happens there will only modestly resemble what happens in the KC MSA, not least because of the difference in population density, which can approach 20x.
  5. Mitigate or avoid your own risk (including the risk you pose to others) by both following the hygiene advice we’ve all heard and minimizing your physical interaction with anyone outside your immediate household. Internalize Râ‚€ = b × k × d, where Râ‚€ is the reproduction number of the virus, b is the probability of infection given contact with an infectious person, k is the contact rate, and d is the infectious duration. While the nominal Râ‚€ of COVID-19 is ~3, your personal Râ‚€ can be driven to < 1 by your own behavior.
  6. The general form of the challenge confronting us is abrupt wide variation in formerly relatively constant phenomena. In Talebian terms, we have migrated from “mediocristan” to “extremistan.” The multiplicative nature of a novel viral pandemic, especially by comparison to the relatively predictable seasonality of influenza viruses, has a thick-tailed (power law) probability structure and complex payoffs (notoriously ranging from large numbers of nearly asymptomatic cases to abruptly life-threatening “cytokine storm” reactions). For detail, see The Fourth Quadrant: A Map of the Limits of Statistics.
  7. So we find ourselves at serious risk of running out of ventilators, ICU beds, and even hospital beds generally, to say nothing of supplies (but see “all disasters are local,” above), raising the prospect of significant second-order mortality among those unable to obtain adequate care for entirely unrelated illnesses and injuries.
  8. In this connection, many prior customs, techniques, tools, and materials are being revealed as highly dysfunctional and, if all goes sufficiently well, will be swept into the dustbin of history. The bad news for me is that my earlier fears about easily-bottlenecked processes have been realized. But we may look forward to significant adaptation, including deregulation of medical services.
  9. Similarly, a large number of purported fixes and remedies will fail. Folk remedies, in particular, seem likely to be disastrous, and this blog’s audience needs no persuasion that attempts at central planning will fail thanks to the Hayekian local knowledge problem. In that connection, and to quote something I wrote a few years back: “John Gilmore famously said that ‘the Net interprets censorship as damage and routes around it.’ The future adaptation of representative democracies will depend on our capability, as individuals, to interpret endemic institutional dysfunctionality as damage and route around it.”
  10. The relatively vulnerable are closer to the center of the network: affluent, living in high-density major cities, well-traveled, extroverted, socially active, with large numbers of regular contacts (even if mostly in a “bubble” as per Murray’s notorious quiz). But some are the alienated and defiant who reject risk avoidance or even risk mitigation tactics (or attempt folk remedies instead), ordinarily associated with …
  11. The relatively invulnerable, who are at or near the edge of the network: impoverished, living in rural or low-density metro areas, untraveled, introverted, socially isolated, rarely in face-to-face contact with others. Many of these people have mental health issues and associated substance abuse problems. But the relatively invulnerable are also the intelligent and conscientious who promptly adopt appropriate risk management strategies.
  12. The post-pandemic preferences of the relatively invulnerable will have massive economic and cultural effects. I expect a reasonably quick partial recovery from the economic shutdown, but full recovery may take several years. Many of the “third places” which have done well over the last few decades will not regain their patronage, and as of early April 2020, we can only guess which ones. Fond hopes of some of my co-religionists aside for a sudden revival, I believe church attendance and involvement will be well down in the aftermath, and will not significantly grow until the next “Awakening,” which per Strauss and Howe should occur at mid-century. Until then, believers will be culturally marginalized and congregations will be smaller—but comprised of relatively fervent, active members.
  13. Geopolitical risks are heightened, especially US-China tensions, and if Xenakis’ “58-year hypothesis” holds, this very year will see an echo of the Cuban Missile Crisis.
  14. The most important output of this process—and it is a process, with inputs, providers, outputs, recipients, etc—will be a collective lessons-learned database, comprised of both tacit and explicit knowledge, and somehow transmitted to future generations.

Retrotech — With a Future?

by

Before there were electronic digital computers, there were mechanical analog computers. Although now obsolete for practical computation, these devices might actually have an useful future ahead of them–in education.

Mechanical analog computation (analog  means that calculation is done by measuring rather than by counting) goes back to the Greek  Antikythera mechanism  (65 BC), which was used to predict the positions of heavenly bodies. The modern era of analog computing began with the work done by James Thompson and his brother William (Lord Kelvin) in the 1870s. First, James Thompson created a mechanical device that performs the calculus function of  integration.

Lord Kelvin applied this device…along with other mechanisms for addition and trigonometric functions…to create a mechanical tide-prediction system. These tide predictors had a pretty good run: the invention was announced in 1876, and some of these systems were still in use in the early 1970s!

For those who haven’t studied calculus, integration can be thought of as a kind of continuous addition.  Imagine a hose with a fluctuating flow rate filling a pool: by integrating the rate of flow, you can calculate the volume of water added to the pool.

The basic concept of a mechanical integrator is shown below.

mechanical-integrator-modified

If the vertical shaft is turned at a constant rate, and the small wheel is moved in and out according to the changing value of some some variable Y, then the rotation of the horizontal shaft Z will represent the integral of Y with respect to time.  If Y is the rate of flow of the a hose, Z will be the total volume  added to the pool. If Y represents the acceleration of a vehicle, then the output shaft will give that vehicle’s speed at any moment.  Connect the output to the input of another integrator, and you will get the distance traveled.

Vannevar Bush, who would become Roosevelt’s science adviser during WWII, combined the integrator and other computing mechanisms to create a highly general mechanical computer, called a  differential analyzer. Completed in 1931, it was not restricted to a single application, but could be programmed–with a wrench and screwdriver to alter the connections–for a wide range of problems. Complex chains of calculation were possible, including the ability for a result at one stage to be fed back as input at an earlier stage–for example, the speed of a simulated vehicle affects its air resistance, which in turn influences its acceleration…which integrates back to its speed.

Other differential analyzers were built in the U.S.,  Norway, and Britain, and were used for applications including heat-flow analysis, electrical network stability analysis, soil-erosion studies, artillery firing table preparation, and studies of the loading and deflection of beams. It is rumored that a British analyzer was used in the planning for the bouncing-bomb attack on German hydroelectric dams during WWII. Differential analyzers appeared in several movies, including the 1951 film When Worlds Collide  (video clip). The ultimate in mechanical analog computation was the Rockefeller Differential Analyzer, a rather baroque (and very expensive) machine built in 1942. It was  decommissioned in 1954, on the belief that the future of calculation would belong to the electronic computer, and especially the electronic  digital  computer.   Following the decommissioning, the mathematician Warren Weaver wrote:

It seems rather a pity not to have around such a place as MIT a really impressive Analogue computer; for there is vividness and directness of meaning of the electrical and mechanical processes involved… which can hardly fail, I would think, to have a very considerable educational value. A Digital Electronic computer is bound to be a somewhat abstract affair, in which the actual computational processes are fairly deeply submerged.
