autonomous trucks

This article from Wired brings up a couple points about autonomous trucks I hadn’t thought of before.

The startup Peloton is working on “platooning” trucks, or groups of vehicles that communicate via a wireless connection that helps them time their movements. At some point soon, the system might let a lead driver take over the steering for a bit, while those at the wheels in the vehicles behind could snooze, catch up on paperwork, meditate, whatever. California-based Embark would like to see driver-monitored trucks pilot themselves on interstates but be manually driven into warehouses by nimbler humans. Starsky Robotics has a similar vision, but says that the trickier driving maneuvers could be done by a human in a remote location, Predator drone-style. It’s unclear if any of these companies want—or will be able—to ever take the human out of the picture entirely…

So you could have one driver or no drives for a whole line of trucks on the highway. Then, when they get to town, a driver or even a remote driver could bring them in one at a time, if the computers are not yet up to the job.

One thing I think about is that this sounds a lot like trains. It’s hard for me to believe that platoons of trucks will be cost-effective with trains even after you take most drivers out of the equation. But remember that the highway system is automatically funded by all highway users through the gas tax, while rail companies are required to build and maintain their own infrastructure. Politicians in rural areas, which are greatly overrepresented in our electoral system at the state and federal levels, like this system because it makes taxpayers in the economically productive areas (aka cities) fund inefficient road networks in the mostly empty rural areas they represent. So this is not a level playing field where victory goes to the most efficient technology.

“sonic attacks” in Cuba

This is a bizarre story about “sonic attacks” on U.S. diplomats in Cuba.

The United States delivered an ominous warning to Americans on Friday to stay away from Cuba and ordered home more than half the U.S. diplomatic corps, acknowledging neither the Cubans nor America’s FBI can figure out who or what is responsible for months of mysterious health ailments…

To medical investigators’ dismay, symptoms have varied widely. In addition to hearing loss and concussions, some people have experienced nausea, headaches and ear-ringing. The Associated Press has reported some now suffer from problems with concentration and common word recall.

Some U.S. diplomats reported hearing loud noises or feeling vibrations when the incidents occurred, but others heard and felt nothing yet reported symptoms later. In some cases, the effects were narrowly confined, with victims able to walk “in” and “out” of blaring noises audible in only certain rooms or parts of rooms, the AP has reported

So the facts are that people are reporting symptoms and bizarre experiences, and nobody has figured out what or who is causing it.

estate tax and pants on fire

Donald Trump’s pants are on fire when he talks about the estate tax, according to Politifact.

How about small businesses and farms? The center projected that only about 80 small farms and closely held businesses would pay any estate tax in 2017. That would amount to about 1 percent of all payers of the estate tax that year. And the estate tax revenue from small businesses and farms, the center said, would amount to fifteen-hundredths of 1 percent of the total paid under the estate tax in 2017.

So, getting rid of the estate tax would hardly “protect millions of small businesses and the American farmer,” as Trump put it.

Trump’s claim doesn’t hold up even if you account for small businesses and farms that would potentially benefit from elimination down the road. The number from the Tax Policy Center (80) only refers to the number of small businesses and farms that would have to pay the tax this year.

When Donald Trump opens his mouth, all I see is diarrhea coming out. His words mean nothing to me. He has no interest in even trying to find out if the things he is making up are true. Is it possible he thinks they are true because he says them? It is a sad and embarrassing time to be an American.

U.S. recyclables sent to China

I had no idea this was going on, but it turns out a lot of what I put in my curbside recycling bin has been sent to China. According to Bloomberg it works something like this: Because of the large trade imbalance between the U.S. and China, container ships that bring manufactured goods from China to the U.S. would end up going back to China empty. Rather than doing that, they are willing to take recyclable trash back to China to next to nothing. And Chinese factories are very happy to have it as raw materials to manufacture more things to send to us. An interesting implication, to me, is that the volume of trade between the two countries must be roughly equal, but the weight and dollar amount must be very unequal.

Another interesting factoid is the top export categories (from the U.S. to China) by dollar amount:

The U.S last year exported more than 37 million metric tons of scrap commodities valued at $16.5 billion to 155 countries, said Adler of the Institute for Scrap Recycling Industries. China accounted for almost one-third of that total—about $5.2 billion.

By comparison, the top two export categories to China in 2016 were miscellaneous grain, seeds, and soybeans ($15 billion) and aircraft ($15 billion).

The focus of the article is actually that China is changing its rules to require cleaner materials before it will accept them, and that could disrupt this market. How dare they! I also heard on the fake news that giant killer hurricanes are actually a hoax created by the Chinese government.

U.S. home prices highest in riskiest areas

According to Bloomberg,

The chart comes from Attom Data Solutions’ natural hazard index, which matches geographic areas to government data on risk of flood, earthquake, tornado, wildfire, hurricane, and hail.

The riskiest 20 percent of U.S. counties have the most homes, the highest average home values, and the greatest price appreciation in recent years. Why? Buyers who pay premiums for ocean views and mountain lookouts may be getting some additional disaster risk as part of the bargain, said Daren Blomquist, senior vice president at Attom. Those kinds of geographical attributes are likely secondary factors in driving price appreciation, though. More importantly, Attom’s list of disaster-prone areas overlaps with engines of economic activity.

This makes sense to me – it is probably just that the big, vibrant U.S. cities are in hurricane and flood prone coastal areas, in fire-prone Mediterranean climates, or both. Climate change is not going to reduce these risks. Having the earthquake risk thrown on top is kind of just bad luck.

game of (bee) thrones

Queen bees demand, and receive, absolute loyalty from their hives. When they are nearing the end of their reigns, they try to arrange to keep their family in power and have one of their daughters assume the throne. But that doesn’t always work out and the struggle over succession can be pretty brutal. This might give George R.R. Martin some ideas.

As far as I can tell, my queen died sometime in the spring. Queens typically live for about four or five years, so this caught me by surprise. A new queen, however, is a regular event in the life of a hive. Beekeepers frequently replace their queens every year or two to introduce genetic variety and ensure that the hive has a strong monarch who can lay enough eggs to keep the population up. Bees can also raise their own queen, and when I did an inspection early that spring, I was pleased to see that mine had taken the initiative. Before she died, my old queen must have laid a few fertilized eggs that worker bees raised as replacements. They would have selected six or seven fertilized (female) eggs and fed them only royal jelly. When the first queen hatched, she would have immediately killed any unhatched competition and ideally flown a few mating flights, storing enough semen in her abdomen to spend the rest of her life laying eggs.

While a newborn queen may seem ruthless, the success of a beehive hinges on allegiance to its queen. Though she can mate with an average of 12 different drones, there is only one queen, which makes for a hive of closely related bees. As a new queen begins to produce her own pheromones, the hive slowly aligns with her as the old bees die and new workers hatch. In a sense, the hive is genetically wired to be loyal to the monarchy. If the hive was to raise multiple queens, or if the workers were to start laying eggs, the interests of the population would slowly fracture…

Bees have about 165 pheromone receptors on their antennae and though it’s not entirely clear how workers “decide” what to do and when (the question of agency is still very much up for debate), it is certain that the queen’s pheromones prompt them to go about their business. When the reigning monarch dies or stops laying eggs in her old age, the change in her pheromones prompts the hive to raise a replacement, as my hive had done. Similarly, if a new queen arrives and releases her pheromones before those of the old queen have dispersed, the hive will consider the new queen an invader, and kill her. Above all, they are loyal to their queen. I did not fully grasp this fact. Because I waited only six hours between queens, the worker bees probably stung my new queen to death within an hour.

lugenpresse

Today’s German lesson: lugenpresse translates literally as “lying press”, but it wouldn’t be much of a stretch to translate it as “fake news”. In fact, the German version was heard at rallies during the Trump campaign apparently. This is a bit of history on the term from the Washington Post:

A decade later [the 1920s], it had turned into an explosive and stigmatizing propaganda slogan, used to stir hatred against Jews and communists. Critics of Adolf Hitler’s regime were frequently referred to as members of the “Lügenpresse apparatus.”

Until today, the word has an anti-Semitic connotation, and it implies hatred not only against journalists but against everyone who opposes the “will of the people.” That abstract concept emerged during World War II when Hitler sought to propagate the idea that Germans were a “master race” superior to all others, especially Jews and Slavic people.

The consequences of that rhetoric — of which the term “Lügenpresse” was an important component under propaganda minister Joseph Goebbels — were horrifying. Millions of people were killed in concentration camps by the Nazis, including Jews, political opponents and homosexuals.

Trump is ignorant of history at a minimum, and I think he has fascist tendencies. But I am only now beginning to think he is using actual, thinly-veiled Nazi-inspired propaganda. It’s evil.

 

the decline and fall of the U.S. empire

Okay, it is not falling quite yet, but The Intercept has a review of two books that make a persuasive case we are witnessing its decline.

Wright sees the system under threat from a combination of newly emerging powers and recent American missteps. McCoy, for his part, sees the unraveling of the U.S. empire as analogous to the series of events that led to the decline of the British and French empires before it. The first step is the loss of support from local elites in territories under imperial influence, a process that McCoy says is clearly underway for the U.S. in many critical regions of the world. In recent years, America has seen its ties strained with military partners such as Turkey, the Philippines, Pakistan, and Saudi Arabia, while major U.S. allies like Germany and South Korea have increasingly come to question America’s capacity to continue leading the imperial system that it created.

It is the Arab Spring uprisings against mostly pro-U.S. dictators, however, that McCoy says marked the slow beginning of the end of American imperium. While the revolts are widely judged to have failed in bringing about liberal democracy, they did succeed in unseating longtime American allies in Tunisia and Egypt, while straining U.S. ties with Gulf Arab countries and even Iraq. As McCoy writes, “All modern empires have relied on dependable surrogates to translate their global power into local control.” He adds, “For most of them, the moment when those elites began to stir, talk back, and assert their own agendas was also the moment when you knew that imperial collapse was in the cards.” The British empire famously became a “self-liquidating concern” when local elites across the empire began demanding self-rule, as did France’s far-flung rule when it was forced to wage a grinding war of attrition to keep control over Algeria. The Arab Spring and the forces it unleashed, which have reduced U.S. influence while exhausting its resources to deal with terrorism and migration, “may well contribute, in the fullness of time, to the eclipse of American global power…”

Partly as a consequence of so many self-inflicted losses, China, Russia, and Iran have all mounted growing challenges to American hegemony in recent years, contesting the tenets of the U.S.-enforced order in the South China Sea, eastern Europe and the Middle East, respectively. Russia has successfully annexed territory and asserted its influence along its periphery, in places like Ukraine, while China has moved ahead with plans to put the economically-vital South China Sea region under its control. Instead of a world in which a hegemonic U.S. enforces the political and economic rules of engagement in these regions, its now possible to see a future in which the world is carved up into a “spheres of influence” system that gives regional powers wide latitude to set the agenda in their immediate neighborhood.

Love the republic, hate the empire. Or at least let the empire go and maybe breathe a sigh of relief to let some of the self-imposed responsibility go with it. But if we are going to do that, we need to support and strengthen international institutions that promote peace, trade, and human rights. Instead we seem to be abandoning those institutions at the same time we are abdicating responsibility.

Carl Sagan’s Baloney Detection Kit

In this essay Carl Sagan suggests a set of guidelines for using the scientific method to decide if something is true.

  • Wherever possible there must be independent confirmation of the “facts.”
  • Encourage substantive debate on the evidence by knowledgeable proponents of all points of view.
  • Arguments from authority carry little weight—“authorities” have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities; at most, there are experts.
  • Spin more than one hypothesis. If there’s something to be explained, think of all the different ways in which it could be explained. Then think of tests by which you might systematically disprove each of the alternatives. What survives, the hypothesis that resists disproof in this Darwinian selection among “multiple working hypotheses,” has a much better chance of being the right answer than if you had simply run with the first idea that caught your fancy.
  • Try not to get overly attached to a hypothesis just because it’s yours. It’s only a way station in the pursuit of knowledge. Ask yourself why you like the idea. Compare it fairly with the alternatives. See if you can find reasons for rejecting it. If you don’t, others will.
  • · Quantify. If whatever it is you’re explaining has some measure, some numerical quantity attached to it, you’ll be much better able to discriminate among competing hypotheses. What is vague and qualitative is open to many explanations. Of course there are truths to be sought in the many qualitative issues we are obliged to confront, but finding them is more challenging.
  • If there’s a chain of argument, every link in the chain must work (including the premise) not just most of them.
  • Occam’s Razor. This convenient rule-of-thumb urges us when faced with two hypotheses that explain the data equally well to choose the simpler.
  • Always ask whether the hypothesis can be, at least in principle, falsified. Propositions that are untestable, unfalsifiable, are not worth much. Consider the grand idea that our Universe and everything in it is just an elementary particle—an electron, say—in a much bigger Cosmos. But if we can never acquire information from outside our Universe, is not the idea incapable of disproof? You must be able to check assertions out. Inveterate skeptics must be given the chance to follow your reasoning, to duplicate your experiments and see if they get the same result.

He goes on to “round out the toolkit” with a list of logical fallacies and rhetorical tricks to be aware of.

Battlefield Casualties and Ballot Box Defeat

This surprising study from Boston University and University of Minnesota concludes that military families that suffered casualties in the Afghanistan and Iraq wars might have been the swing voters that put Trump over the top in Pennsylvania, Michigan, and Wisconsin.

Kriner, Douglas L. and Shen, Francis X., Battlefield Casualties and Ballot Box Defeat: Did the Bush-Obama Wars Cost Clinton the White House? (June 19, 2017). Available at SSRN: https://ssrn.com/abstract=2989040

America has been at war continuously for over 15 years, but few Americans seem to notice. This is because the vast majority of citizens have no direct connection to those soldiers fighting, dying, and returning wounded from combat. Increasingly, a divide is emerging between communities whose young people are dying to defend the country, and those communities whose young people are not. In this paper we empirically explore whether this divide—the casualty gap—contributed to Donald Trump’s surprise victory in November 2016. The data analysis presented in this working paper finds that indeed, in the 2016 election Trump was speaking to this forgotten part of America. Even controlling in a statistical model for many other alternative explanations, we find that there is a significant and meaningful relationship between a community’s rate of military sacrifice and its support for Trump. Our statistical model suggests that if three states key to Trump’s victory – Pennsylvania, Michigan, and Wisconsin – had suffered even a modestly lower casualty rate, all three could have flipped from red to blue and sent Hillary Clinton to the White House. There are many implications of our findings, but none as important as what this means for Trump’s foreign policy. If Trump wants to win again in 2020, his electoral fate may well rest on the administration’s approach to the human costs of war. Trump should remain highly sensitive to American combat casualties, lest he become yet another politician who overlooks the invisible inequality of military sacrifice. More broadly, the findings suggest that politicians from both parties would do well to more directly recognize and address the needs of those communities whose young women and men are making the ultimate sacrifice for the country.

I acknowledge and am willing to believe the numbers. I am not sure I buy the conclusions these authors draw from the numbers – that communities with ties to the military will vote for candidates they think are least likely to send their children off to war. On the contrary, I would hypothesize that people in these communities might respond more strongly to patriotic rhetoric, and be more likely to support military approaches to geopolitical problems.
