How GDP Hides Industrial Decline

October 19th, 2025

Patrick Fitzsimmons has been mulling a paradox:

U.S. GDP keeps going up, yet it seems like we make less stuff and that most of the smart people I know work fake jobs. Growing up in the nineties, most of my toys and clothes had tags saying “Made in Hong Kong” or “Made in Vietnam.” But the high-skill, high-tech goods—the washing machine, the car, my computer—were often made in America. Now? From my e-bike to my laptop, from my refrigerator to my mattress, very few goods I own, high-tech or low-tech, were made in the USA.

[…]

Sometimes there are discrepancies between your real-world observations and the data. But this goes far beyond just being a discrepancy: the data is saying the complete opposite of what we see with our own eyes, hear from our acquaintances in the job market, and deduce logically from our knowledge of demographics, technology, industry, and trade. How is this possible? The answer is actually very simple: the data is completely wrong. But you can only figure this out if you go line-by-line into the hundreds of pages of government GDP calculation methodology documentation. Which is exactly what I did.

[…]

I challenge anyone who believes in these statistics to tell me what in the real world happened so that raw tonnage of steel was down, real gross output of steel was flat, usage of inputs was up, but “real value-added” was also up, and up hugely. Nobody can explain these numbers. The BEA cannot—I have asked them! If the raw data still exists, nobody has access to it because it was confidential.

The basic problem is that real value-added calculations only work if there are no quality adjustments and there hasn’t been any substitutions in the inputs. If those assumptions do not hold, you can get wild and nonsensical results. Since those assumptions do not actually hold in the real world, those nonsensical results are mixed into the overall calculation in ways that are impossible to account for, thus making the entire number bogus.

My guess is that what happened with steel production is that factories have moved from using raw iron ore to scrap metal as an input. The scrap metal is actually closer to a final good and requires much less energy to turn into steel. But GDP calculations do not know that scrap metal is closer to a final good. What the GDP calculations see is that materials have become more expensive and that energy inputs are less, so it seems like the steel factories are maintaining output with much less input, and thus value-added is greater. The reality, though, is that the United States is not producing any more steel out of factories, the United States is not producing a greater percentage of the steel value chain than in 1997, and the 125% increase in real value-added is a spurious result that represents neither making more stuff nor making better stuff.

[…]

This is not just my critique: a former deputy chief at the BEA, Professor Doug Meade, has sharply criticized real value-added as a metric. In a 2010 conference paper, he wrote, “more than 60 years after it was first introduced, there is still no fundamental agreement on the meaning of real value added, or its price. Most who use it for the study of productivity loosely describe it as a measure of ‘real output’ although strictly speaking it is not that.” He continues to argue that comparing real value-added between years only works under the conditions of no quality adjustments, no input substitutions due to price changes, and no changes to the terms of trade. If those conditions do not hold, then, he says diplomatically, “it would be unclear what [real value-added] is measuring” Or as economist Thomas Rymes, observing the same issues, put it more directly: “a fictitious measure of output with no meaning.”

[…]

Since nominal value-added is not adjusted by price indexes, it avoids all the problems we discussed with real value-added.

But, once again, the problem with the nominal value-added comparison is that it is not a comparison of actual things—it is a comparison of sales receipts. Thus a given quantity of products that is produced by a bloated cost structure will count as more “GDP” than the same number of products produced by an efficient factory. This is not just a theoretical problem—we know for a fact that the Chinese company BYD produces an equivalent to the Tesla Model 3 for half the price. Thus, $30,000 of manufacturing value-added in the U.S. might represent one car being produced, while for China it might represent two cars, and thus is actually double the output. In general, the China-U.S. dollar exchange rate is not a market rate and thus the conversion does not reflect in any meaningful sense the value of products.

Worse, many U.S. products are more expensive not because they are higher-end and better quality, but because they are protected from competition by tariffs, patents, regulation or national security requirements. For instance, Purism makes an all-in-the-USA phone for $2,000—the phone is no better than a $500 Chinese or South Korean phone, but sells at a premium for the U.S. security market. Others in procurement tell stories of getting quotes for printed circuit boards that cost $5,000 from China but $50,000 in America, thus only government and regulated industries buy American circuit boards. American-made municipal buses can cost three times the price as those made in China, but cities often face rules requiring them to buy American. For a particularly egregious example, thanks to the protections of the Jones Act, American ships cost an astounding ten times as much to build as their foreign counterparts.

[…]

Which is more “output”—one million drones sold for a total of $2 billion dollars, versus one B2 stealth bomber for the same price? A $2,000 custom-made dress for the Met Gala, or one hundred pairs of denim work pants? Nominal value-added comparisons treat them as equivalent.

Nominal value-added cannot tell the difference between a country like 1790s Spain, a manufacturer of luxury goods with inflated nominal prices thanks to New World gold, and 1790s England, a ruthless manufacturer of inexpensive goods that is on its way to world domination. A comparison between countries that simply looks at sales revenues—not at the actual amount of ships, phones, and things produced for that revenue—is simply not a useful comparison.

[…]

When we read a headline saying GDP data shows “car output has increased,” we think the U.S. has made more cars. We then apply our own views as to whether the quality of the car has changed. When we sneak quality into a measure but still call it “output,” we are double-counting and embedding the subjective in the objective, and we lose track of the hard numbers. We are not making more quantity of cars per person like the data says, we are making fewer cars, but with Bluetooth and crumple zones.

[…]

While the BLS provides general information about the quality adjustment process, the specific methodology and the actual decisions are not documented. At the heart of GDP we find this subjective, bureaucratic black box. When we see that “output” of cars has increased since 1997, it is impossible for any commentator to know how that increase in “output” breaks down between actual number of cars, horsepower boosts, safety features, durability improvements, convenience features, blue tooth, power locks, and on and on.

[…]

The point is not that any of these methods is right or wrong. The point is that if you have a half-dozen plausible ways of adjusting for quality, none of which from first principles is more objective than another, and you rule out one method for giving ludicrously low results, and one method for ludicrously high results, and just choose a middle route that feels reasonable, then the result of this adjustment is not an objective measure of output. All you have done is launder vibes into something that has the appearance of an objective number.

You can’t just compare tax rates

October 18th, 2025

Brian Albrecht explains why you can’t just compare tax rates between, say, income taxes and tariffs:

Double a tax rate, and you quadruple the deadweight loss. This is a standard result in public finance, and it suggests we should spread our tax burden across many bases rather than concentrate it in one place.

Here’s the intuition. When you impose a small tax, you only kill off marginal transactions—deals that barely made sense in the first place. The buyer was almost indifferent about purchasing, or the worker was almost indifferent about working that extra hour. These marginal transactions don’t create much surplus, so losing them doesn’t cost much.

But as you increase the tax rate, you start killing off transactions with larger and larger surplus. Beyond eliminating the deals that barely made sense, you’re now eliminating deals where both parties really wanted to trade, where there were substantial gains from the exchange. The surplus lost from these inframarginal transactions is much larger.

This is why deadweight loss grows with the square of the tax rate. Double the tax, and you lose transactions that had twice the surplus. The effect multiplies. A 10% tax might eliminate deals that create $1 of surplus each, but a 20% tax eliminates deals worth $1 and deals worth $2. The total loss is 4x, not 2x.

[…]

If you want to compare across markets, you need another basic idea from taxation: deadweight loss depends on elasticities.

[…]

Some supplies are essentially fixed—you can’t create more of them no matter how high the price goes. Other goods can be produced in unlimited quantities at constant cost. Some demands are highly elastic (people readily substitute to alternatives), while others are inelastic (people need the good regardless of price). These elasticities determine how much distortion a given tax rate creates. The tax rate alone tells you nothing.

More elastic demand or supply curves generate larger deadweight losses. The flipside is the classic Ramsey result: tax less elastic goods more heavily.

[…]

Consider taxing a good with a perfectly inelastic supply—say, land in a specific location. The supply curve is vertical. No matter what price landowners receive, they supply the same amount of land because they can’t create more of it. By definition, there is no deadweight loss. The tax doesn’t change behavior.

What happens when we increase the tax rate on land? The tax raises revenue, but it generates no deadweight loss. Landowners absorb the entire tax through lower prices, but the quantity of land traded doesn’t change. There’s no distortion in the allocation of resources. You could tax land at 100%, and the deadweight loss would still be zero.

This demolishes the idea that you can look at tax rates in isolation. There is no nice connection between tax rate and deadweight loss that transcends the specific good being taxed.

Now compare this to a tariff on imported goods, where supply and demand are both elastic. The tariff creates a wedge between what consumers pay and what producers receive. This wedge distorts both consumption decisions (people buy less than they would otherwise) and production decisions (domestic producers make more than they would in an undistorted market). We get the classic deadweight loss triangle.

And it’s not just that imports aren’t perfectly inelastic. They’re very elastic! Estimates vary but one recent paper puts the long-run elasticity at 14, implying a huge deadweight loss.

The formula that deadweight loss increases with the square of the tax rate applies to both taxes. It tells us doubling tariffs with quadruple the deadweight loss. But it tells us nothing about which tax we should increase and the deadweight loss across the two markets. The land tax, even at a 100% rate, might generate zero distortion. The tariff, even at a 2.5% rate, creates real costs because of the huge elasticities. Elasticities matter. You can’t compare tax rates across different bases without accounting for how responsive behavior is to each tax.

[…]

But tariffs are worse than general consumption taxes because they tax only some goods—and imports are a small share of total consumption.

In the US, imports are roughly 10% of consumption. This means tariffs apply to a base that’s one-tenth of a general consumption tax would. When Lott compares a 2.5% tariff to a 40% income tax, he’s ignoring that these rates apply to completely different denominators.

Think of it this way: if you want to raise $100 from a tax that applies to everyone’s $1,000 of consumption, you need a 10% rate. But if you want to raise that same $100 from a tax that only applies to $100 of imports (10% of consumption), you need a 100% rate. The narrow base means you need a much higher rate to raise equivalent revenue.

This logic applies to any narrow excise tax.

He never took lessons and never looked back

October 17th, 2025

Paul Daniel “Ace” Frehley, co-founder and lead guitarist of the legendary rock band Kiss, has died following injuries suffered during a fall last month, Variety reports:

In an era that preceded MTV, their performances were almost overwhelmingly visual and experiential, with explosions, elevators and more. Yet the mystique of Kiss was key: the bandmembers’ faces were not revealed for more than a decade, by which point Frehley and drummer Peter Criss had left the band. Frehley was known as “Space Ace” and cultivated an otherworldly image.

[…]

Paul Daniel Frehley was born to a musical family in the Bronx borough of New York City and received an electric guitar as a Christmas present in 1964. He never took lessons and never looked back: citing Jimi Hendrix, Buddy Guy, Jeff Beck, the Rolling Stones, Led Zeppelin and the Who as his primary influences, he began playing in bands as a teenager and purportedly acquired his nickname from friends based on his ability to score dates with girls.

He dropped out of high school after one of his bands, Cathedral, began earning money, but later returned and got his diploma. He continued playing and by 1971, one of his bands, Molimo, signed with RCA Records and recorded several unreleased songs for the label. But late the following year, a friend spotted an advertisement in the Village Voice that turned out to be for the lead guitar slot in the embryonic Kiss. Famously, Frehley went to the audition in Manhattan wearing one red sneaker and one orange one. Stanley, Simmons and Criss were dismayed by his appearance but sufficiently impressed with his fiery lead guitar work, and he was invited to join a few weeks later. The band, which was preceded by Stanley and Simmons’ previous group Wicked Lester, dubbed themselves Kiss in January 1973 and soon, inspired by the New York Dolls and Alice Cooper, began painting their faces and crafting outrageous costumes for their concerts.

[…]

Frehley’s abuse of drugs and alcohol grew worse, and in May of 1983, he was arrested following a high-speed chase on the Bronx River Parkway in his 1981 DeLorean. He was charged with DUI, reckless driving and leaving the scene of an accident after hitting four cars during the incident (luckily with no injuries). He spent two weeks in a hospital detox unit and was required to attend Alcoholics Anonymous meetings.

Patients who inhaled heparin were half as likely to require ventilation

October 16th, 2025

Heparin, a widely available and affordable treatment for blood clots, has been shown to be effective in treating serious COVID-19 cases, according to a new international study led by researchers at the Australian National University (ANU) in collaboration with King’s College London:

The study analyzed data from almost 500 patients hospitalized with COVID-19 across six countries. Patients who inhaled heparin were half as likely to require ventilation and had a significantly lower risk of dying compared with those receiving standard care.

Heparin, a drug traditionally injected to treat blood clots, was tested in this study in an inhaled form, targeting the lungs directly. As well as acting as an anticoagulant, heparin has anti-inflammatory and pan-antiviral properties. Earlier research results showed breathing and oxygen levels improved in COVID-19 patients after they inhaled a course of heparin.

The researchers believe the drug could also be useful in fighting other serious respiratory infections such as pneumonia.

The natural porous structure of the wood has been collapsed and toughened

October 15th, 2025

Superwood” has just launched as a commercial product, manufactured by InventWood, a company co-founded by material scientist Liangbing Hu:

While working at the University of Maryland’s Center for Materials Innovation, Hu, who’s now a professor at Yale, found innovative ways to re-engineer wood. He even made it transparent by removing part of one of its key components, lignin, which gives wood its color and some of its strength

His real goal, however, was to make wood stronger, using cellulose, the main component of plant fiber and “the most abundant biopolymer on the planet,” according to Hu.

The breakthrough came in 2017, when Hu first strengthened regular wood by chemically treating it to enhance its natural cellulose, making it a better construction material.

The wood was first boiled in a bath of water and selected chemicals, then hot-pressed to collapse it at the cellular level, making it significantly denser. At the end of the weeklong process, the resulting wood had a strength-to-weight ratio “higher than that of most structural metals and alloys,” according to the study published in the journal Nature.

[…]

“It looks just like wood, and when you test it, it behaves like wood,” Lau added, “except it’s much stronger and better than wood in pretty much every aspect that we’ve tested.”

[…]

“In theory, we can use any kind of wooden material,” Lau said. “In practice, we’ve tested with 19 different kinds of species of wood as well as bamboo, and it’s worked on all of them.”

InventWood says Superwood is up to 20 times stronger than regular wood and up to 10 times more resistant to dents, because the natural porous structure of the wood has been collapsed and toughened. That makes it impervious to fungi and insects. It also gets the highest rating in standard fire resistance tests.

Megaprojects figure heavily into Chinese culture

October 14th, 2025

Megaprojects figure heavily into Chinese culture:

The reason for this is striking and unusual, and originates surprisingly from the vein of “geography is destiny.”

The Yellow River has changed course many times throughout Chinese history. The technical reason for this is that it carries heavy silt load, which it deposits on riverbeds, continually changing the shape of the river and eventually causing the river to find new lower paths, especially during floods.

In the ~2540 years between 595 BC and 1946 AD, the Yellow River has been documented to have shifted its course 26 times.

Because a changing river redefines the shape of the land, it wreaks continual havoc on agriculture. By the cruel process of natural selection, it led to cultures that survived only if they were able to collectively enact flood control megaprojects, driven by sufficiently centralized state power. Tribes and communities who could not band together and execute sufficiently large-scale planning simply died from famines when the next flood destroyed their crops.

In the legends of ancient China, the first Xia dynasty was founded by a king named Yu the Great, or Yu the Engineer, who was purported to have spent 13 years devising a system of flood controls that redirected flood waters into fields and leading the farmers to build them, taming the waters for the first time and establishing the prosperity of the Chinese heartland.

This is why natural disasters are considered a sign of a government losing the “Mandate of Heaven.” An effective government in China is first and foremost responsible for keeping floods at bay and using state power to bring rapid and effective disaster relief to the people. Culturally, it is considered the first and primary function of the government.

Contrast this to American government culture, where the first and primary function of government is collective defense against adversaries. This is not a criticism of one or the other, but reflects an outgrowth of each under different historical influences.

The typical view in the West is that Chinese people accept an “authoritarian” government because they are more submissive and uncreative. This is not exactly true, but rather that there is a stronger cultural norm of supporting the vision of a grand plan (including some that may take years to come to fruition) because history has shown that doing so is sometimes an existential matter — and the upside can be huge prosperity gains for all.

Sometimes you have to spend years enacting flood control systems, or decades building a really huge wall, or developing a massive technology and industrial base, so that dangerous things don’t wipe you out. Having a history full of disasters AND averted disasters shapes culture in a certain way.

People talk about how Northern European cultures were forced to develop long-term planning because of seasonal cycles: they couldn’t just assume food would grow all the time, so they had to farm and harvest and save during the summer so as to have food during the winter.

Chinese culture developed in even more extreme ways: not only did seasons force that kind of long-term planning, but periodic disasters would wipe you out unless many many communities banded together to execute megaprojects necessary to defend against those disasters. It wasn’t just about sustained effort over months, it was sustained effort over years. The alternative was starvation, and the cultures that survived knew the value of collective long-term plans under practical leaders.

Natural disasters befell other cultures too, but the difference here is critical: some disasters are irresistible acts of God. Other disasters are difficult but not impossible — and periodic floods and changing rivers fall in that category: if you are good enough, smart enough, and work hard all together, you can beat the floods.

This is actually why China had a great respect for America, the only other country that could be seen to execute similar megaprojects: the Hoover dam, the Tennessee Valley Authority Dams, the California Aqueducts, the Manhattan Project, and of course putting a man on the Moon. These are enormous mobilizations of human collective action under visionary leadership. And they are practical.

In Wang Huning’s “America Against America,” one of themes motivating the research he did that led to the book was “How did such a young country rise to such accomplishments?” They were accomplishments on the (relative) scale of things done in earlier eras of Chinese history. America is literally the only other country that China really respects. And it’s not because America has a lot of guns. China got beat up by 8 different countries who all had a lot of guns, but only American builds big.

Unfortunately, that kind of leadership and the willingness to execute megaprojects has stalled in America since the 70s, and has been a source of quiet disappointment. What is viewed by China hawks in the US as hostile competition on the part of China is largely motivated by a sense of China witnessing a country that has accomplished things worthy of learning from. The drive to equal or surpass the US comes only partially from a desire for security but also because the US shows what’s possible, and excels at something deeply valued in Chinese culture.

It is easy to regard the geopolitical frictions of the day as an existential conflict between civilizations, but neither American culture nor Chinese culture are really built on the destruction of competitors. Both are built on a deep-seated constructivism, a belief that every problem can be overcome not by taking from others, but by building a solution at home.

It was all created for a group of extremely religious, highly idealistic women

October 13th, 2025

Girl with a Pearl Earring by Tracy ChevalierArt historian Andrew Graham-Dixon links Johannes Vermeer, the painter behind Girl with a Pearl Earring, to a radical sect:

He was unique in many ways, not least in having painted virtually all his work for a single husband and wife to hang on the walls of their canalside home in Delft. No other great artist ever worked so exclusively for a single client and for a single place — which explains, among other things, why Vermeer was never famous, and quickly forgotten after he died.

The husband and wife were Pieter Claesz van Ruijven and Maria de Knuijt. They lived at a house called the Golden Eagle, filled with Vermeer’s most famous paintings.

[…]

Pieter Claesz van Ruijven was from a family of diehard Remonstrants, his father and grandfather having risked imprisonment by supporting the movement at a time when it was outlawed throughout the Dutch Republic. His wife, Maria de Knuijt, was not only a Remonstrant herself but also participated in the activities of a yet more radical outgrowth of the movement whose followers became known as Collegiants.

Research into Vermeer’s family background shows that he was born and brought up a Remonstrant, and that he too participated in the gatherings of the Collegiants. The same is true of his mother and father, sister and brother-in-law, indeed of almost everyone in his immediate circle. His wife was a Catholic, but she too must have been in sympathy with the Remonstrants, or she could not have married a man so committed to their cause.

[…]

They were pacifists who dared to dream of a Europe in which all nations would live at peace with one another. They were staunch republicans, who regarded even the most supposedly benevolent monarch as a tyrant in waiting. They were egalitarian and extremely charitable, the richest among them giving most of their money away to found orphanages or places of refuge for the old and infirm.

Above all, they believed in, and passionately upheld, the universal freedom of conscience. No one should be constrained to a particular belief, let alone punished or killed for that belief. All should be allowed to practise whatever religion they chose, without fear of persecution. By this they included not only those of every Christian persuasion, but Jews and Muslims too. Tolerance was their golden rule, and it was to be absolute.

Collegiants also believed in the absolute equality of men and women. In fact the majority of Collegiants were women. Many would attend services at the Remonstrant church, where sermons were preached on the virtues of open-mindedness. But they increasingly embraced the ideal of a Christianity without churches of any kind, holding meetings for prayer and Bible reading at home, away from the supervision of priests.

[…]

The assumption behind nearly all writing on Vermeer thus far has been that his works were painted for the open market and should therefore be regarded as genre paintings intended to amuse or entertain. But nothing could be further from the truth. Every single one of his paintings was inspired by the religious beliefs cherished by Maria de Knuijt and those close to her, who included Vermeer himself. Her house was like a church, all of Vermeer’s pictures like a single fresco cycle painted for that church.

[…]

All sorts of things that have until now seemed deeply puzzling about Vermeer’s work — its solemnity of mood, its meditative stillness, its almost exclusively female cast of characters — make perfect sense once we know that it was all created for a group of extremely religious, highly idealistic women who met weekly in the rooms where these pictures once hung.

Girl with a Pearl Earring, made even more famous by Tracy Chevalier’s fictionalised account of the girl in her novel and the film adaptation starring Scarlett Johansson, is likely to be a portrait of Maria and Pieter’s daughter, Magdalena. She would have been 12 in the autumn of 1667, and assuming that she was a Collegiant like her parents, she would have solemnised her commitment to Christ at that age. The picture shows her marking that by dressing as Mary Magdalene, turning, with such depth of feeling, to Jesus Christ.

Most correlations are not causal.

October 12th, 2025

Most correlations are not causal, Crémieux reminds us:

Public health advice provides us with plenty of examples to understand ‘Why?’

Consider sugar. It’s notably declined as a share of the American diet ever since dietary recommendations went out against it.

The people who adopted the advice to drop sugar were disproportionately those who were well-off. That’s sensible, because people who are well-off have more of the time, resources, and wherewithal to follow new advice. We see this all the time. For example, the advice to have babies sleep on their backs to prevent SIDS reduced rates of SIDS death, but also made them more socioeconomically stratified because the people who took the advice last and less well were less well-off parents.

For sugar, this meant much the same: that, over time, sugar in the diet became less associated with education, income, exercising habits, and more associated with bad things like smoking.

In fact, the sugar share of the diet — despite ample coverage of sugar as a problem — wasn’t even associated with BMI until after the issue got really popular with Gary Taubes’ books going viral.

Simply selectively following advice, going along with fads, believing what’s popular and acting on it, and so on, can lead to correlations that ‘make sense’ from some research reference frame, but are not actually true.

[…]

Healthy Adherers.

In the Coronary Drug Project, people who faithfully took an inert placebo had markedly lower mortality than poor adherers—pure selection on being a conscientious, health-seeking person. The pill cannot explain this, so it did not explain this. And, perhaps, some of the available adherence predictors could explain this.

Drinking J-Curves.

In causal studies, drinking appears to be linearly bad. More drink, less health. And this makes total sense because alcohol is poison. But in observational studies, there’s often elevated risk associated with not drinking at all. The reason for this is selection in a few ways, but one of the most important ways is “sick-quitters”: people who quit drinking because they were unwell. Quitting doesn’t eliminate their issues, so they show up as a lump of high-risk non-drinkers and they distort the truly linear relationship between alcohol consumption and harms to health.

Coffee “Was Bad”.

Nowadays, mainstream news outlets frequently report that coffee is linked to better health. These headlines are everywhere, but you would be surprised if you remembered the headlines from a few decades ago. Those headlines routinely linked coffee to worse health. What changed? Smoking declined!

Coffee and smoking go hand-in-hand.

[…]

In older cohorts: more coffee, higher mortality.

In modern cohorts: more coffee, lower mortality.

In older cohorts where we have detailed smoking histories: post-adjustment, the risk goes away and coffee becomes associated with lower mortality.

[…]

If you want to improve your reasoning about the world, then assume selection explains correlations by default. Selection may not explain everything about a correlation, but it could explain a lot of it.

The intricate design is known as a gyroid

October 11th, 2025

Researchers at the Technical University of Denmark (DTU) have 3D-printed a lightweight ceramic fuel cell:

The new process involves 3D printing and results in what the team refers to as the “Monolithic Gyroidal Solid Oxide Cell” (or just “The Monolith” for short).

[…]

The team implemented a custom design inspired by the natural construction of coral. This shape optimizes surface area while the material composition allows for a much lighter-weight end product. Most fuel cells are comprised of metal, which contributes greatly to their weight. This fuel cell is apparently completely ceramic.

The intricate design is known as a gyroid and is a type of triply periodic minimal surface (shortened to TPMS). These surfaces are intended to provide as much surface area as possible. It’s beneficial, particularly in this case, as the surface provides more optimal heat dispersion. According to the development team, the cell is capable of producing more than a watt of power for each gram of its own weight.

The material also has a surprisingly noteworthy amount of durability. When testing the fuel cell’s ability to withstand temperature fluctuations, it managed to handle temperatures as high as 212° F (100° C). It also maintained its structural integrity when alternating between both power-storing and generating modes.

The fuel cell also features something called “Electrolysis Mode” which increases the hydrogen production rate almost tenfold compared to standard fuel cells. The 3D printing aspect of the design also helps make the manufacturing process easier than regular fuel cells.

Primates originated in cold environments

October 10th, 2025

Primates originated in cold environments, not the tropics:

It is easy to see why scientists had assumed primates evolved in warm and wet climates. Most primates today live in the tropics, and most primate fossils have been unearthed there too.

But when the scientists behind the new study used fossil spore and pollen data from early primate fossil environs to predict the climate, they discovered that the locations were not tropical at the time. Primates actually originated in North America (again, going against what scientists had once believed, partly as there are no primates in North America today).

Some primates even colonized Arctic regions. These early primates may have survived seasonally cold temperatures and a consequent lack of food by living much like species of mouse lemur and dwarf lemur do today: by slowing down their metabolism and even hibernating.

Challenging and changeable conditions are likely to have favored primates that moved around a lot in search of food and better habitat. The primate species that are with us today are descended from these highly mobile ancestors. Those less able to move didn’t leave any descendants alive today.

Reading well is an endurance sport

October 9th, 2025

Reading well is an endurance sport, Henrik Karlsson says:

I sometimes talk to people who want to become serious readers and so pick up Kafka’s The Trial or something like that—it is about as pleasant as running a marathon untrained. They often lose their enthusiasm for reading. You have to gradually ramp up your capacity to handle complex ideas and precise prose. I read a few hours a day, and I mostly read books that are comfortable for me to read, well within my range. It is more important to keep the reading experience easy enough that I keep going and going and going, than to always push myself to that edge. By reading within my comfort zone, I gradually build up my stamina and pick up more and more references, words, and patterns of thought, bringing more and more literature into my comfort zone. I remember reading Dostoevsky as a teenager, and I could do it, but it was a chore; these days his prose sounds like an email from a smart friend. It is thrilling when things that were beyond me become easy like that: the world cracks open. If you want to reach the deepest experiences literature provides, you have to put effort into building the stamina and conceptual understanding necessary for complex writing to become transparent to you.

The resistance started to fade as more and more Soldiers came to grips, literally, with the enemy

October 8th, 2025

Matt Larsen describes some lessons learned early in the War on Terror:

As the team entered the second house the number one man seemed to be struggling with something as he went through the first door. The number two man, keying off of the direction taken by number one turned left, the opposite direction from number one which is the standard Close Quarters Battle (CQB) method, and the number three, SSG Miranda came in to follow number one who at this point was obviously engaged with someone. So as not to be stuck standing in the doorway, what is known in CQB as the fatal funnel because enemy fire will normally be concentrated there, Rich placed the palm of his non-firing hand on the back of number one and pushed him and the person he was tangled up with further into the room.

The enemy had a grip on the number one man’s weapon and was fighting to get control of it, although this was not clear to Miranda who was looking at the scene through the narrow green tinted view of his night vision goggles.

While struggling to gain control of his weapon, number one pulled on it as if to rip it out of enemy’s hands. This is known as the “Tug of War” technique, when an enemy has hold of your weapon by the barrel if you simply step back and pull, it will normally be pointed straight at him allowing you to shoot. In doing so he stepped slightly back and toward the center of the room.

With nothing now between him and the man number one had been struggling with, Miranda grasped him with his non-firing hand and using an advancing foot sweep tossed him easily into the center of the room.

At the same moment, with his weapon finally clear enough, number one fired a three round bust into the enemy. Unfortunately with Rich Miranda still grasping the enemy’s shirt, one of the rounds passed through his left arm before striking the enemy.

Miranda himself was one of the more experienced fighters in the entire Special Forces. He had been training, mostly on his own, for years and was an accomplished Judo player and kickboxer.

[…]

The bottom line was simple: their Combatives training and their mission training were separate. The CQB doctrine when the wars in Iraq and Afghanistan started was that if a soldiers’ rifle malfunctioned they should either take a knee so teammates could cover their sector of fire, or transition to a sidearm. In practice neither option works inside the typical urban rooms we fought in, eight to ten feet end-to-end. When you go through that door, it isn’t a marksmanship contest. It is a fight! You shove the enemy against a wall or over furniture, wrestle for control, and then bring whatever weapon, rifle, pistol, or knife, you can to finish it.

Combatives is an inherent part of many types of missions, Close Quarters Battle in particular, and it must be treated as such. At the time, however, it was not. Doctrine and training treated Combatives as a separate, optional subject: role-players were occasionally used to simulate noncombatants, but live Combatives as a integral portion of mission training seldom if ever happened. The prevailing mindset came from leaders shaped by twenty years of peacetime habits who didn’t want to confront the realities of fighting in rooms. The doctrine they produced was weak and the soldiers who followed it were less prepared than they needed to be. Combatives and marksmanship address different ranges; without both integrated into mission training, teams were handicapped before they ever crossed the threshold.

The resistance started to fade as more and more Soldiers came to grips, literally, with the enemy.

After the bomb was dropped he became quickly Commodore and then Rear Admiral

October 7th, 2025

Peggy Bowditch was a young girl when she and her family moved to Los Alamos in 1943, where her father, Rear Admiral William Sterling “Deak” Parsons, was chosen by General Groves to become head of ordnance for the Manhattan Project:

I was eight when we moved there, and just short of eleven when we left after the war. My father had worked on the proximity fuse. Although he was a regular Navy officer, he had worked in science, from the beginning of World War II on. And General Groves picked him and he meshed with Oppenheimer, so he became the head of ordnance at Los Alamos.

[…]

He was Captain, Navy Captain William Sterling Parsons, and later, after the bomb was dropped he became quickly Commodore and then Rear Admiral.

[…]

A spy there under our very roof was our babysitter, Klaus Fuchs. He would come and take care of my sister and me, and since we were five and eight, we did not need much looking after. But we had a piano in the house and he loved to play the piano, so that was our babysitter. Then, when I got a little older, I was actually Peter Oppenheimer’s babysitter. I mean, you should not really trust a ten-year-old to babysit, but you know, with a guard walking around outside, what could go wrong?

[…]

After the war, we certainly continued our friendship with the Oppenheimers and went up to Princeton, oh, it is hard to remember how often. But the friendship continued and it was fun to go and visit them. And I remember I was struggling with my geometry homework, and Kitty Oppenheimer was the one who helped me [Laughs].

And then in December of ’53 my father heard at a cocktail party that Oppie had been separated from his Q clearance, and he was so upset that he came home and began a heart attack, which he checked with the Encyclopedia Britannica, which was his idea of where you go. And it did not sound as if he had a heart attack. The next morning, Mother took him to Bethesda Hospital and he died, a week after his 52nd birthday.

And, of course, Oppie did lose his security clearance.

[…]

General Groves would show up now and then, and he was a terrific administrator. I mean, he got the Pentagon built, and he was head of the Manhattan Project, but he was basically, I would describe his personality as bully. And there was an Army colonel, maybe, Whitney Ashbridge, who was, I think he was a graduate of West Point, and a very nice fellow, but Groves was a regular Army officer and Ashbridge was maybe engineering duty only. So Groves looked down on him. And one morning at inspection time, he and Groves were marching along, the soldiers were coming by, and Groves saw a piece of trash blowing and ordered Ashbridge to pick up the trash in front of the troops, which was really demeaning. I remember my father talking about what a nasty thing that was.

After the war, my parents would still see and they would play tennis with Groves and his daughter [Gwen Groves Robinson]. Groves was the kind of tennis player who did cuts and nasty shots. His daughter, Gwen, she was a good player. But, I remember General Groves asking me, he said, “Would you like me to send your father back to Los Alamos?”

Well, since I loved it, “Oh, yes, yes, yes.” Of course, he was just fooling, just, you know, typical bully type, taking advantage of a kid’s enthusiasm.

My father came and went. He went to Washington quite often. And Groves, I do not know whether he was nervous. For some reason, he was nervous about air transport, so you always travelled by train. That was considered safe, and of course, the trains were pretty nice then. I never got to leave Los Alamos, except to go to Albuquerque or Santa Fe.

They are engaged in cargo cult meaning-making, the pursuit of a pseudo-religion

October 6th, 2025

Freddie DeBoer sees us entering a new period of spectacular acts of public violence:

After decades of unusually low levels of such violence, we may now be returning to conditions similar to those of previous eras where such acts become distressingly common — notably, the turn of the 20th century, with the wave of anarchist assassinations from 1881 to 1914, the Haymarket Affair, and the Galleanist bombings, as well as the “Days of Rage” of the 1970s, including the Weather Underground, the Symbionese Liberation Army, and FALN (the Puerto Rican separatist movement).

[…]

Mass shootings and similar events are now so normalized that it can be difficult to sort out whether we’ve slipped into such an era, but my fear is that recent violence will spread and grow, that in fact each act will serve as an accelerant for the next, as the cascading violence will help the people who commit this violence see their work as part of some broader movement that gives them the meaning they seek.

This is, in fact, my overarching argument: that where we are trained to see public violence as the outcome of ideology — those anarchist assassinations, 9/11, Oklahoma City, Anders Breivik, Yukio Mishima — in the 21st century, a certain potent strain of political violence is not the product of ideology but rather an attempt to will ideology into being through violence itself. To create meaning in a culture steeped in digital meaninglessness by the most destructive means available. The 21st century school shooter (for example) does not murder children in an effort to pursue some teleological purpose; the 21st century school shooter exists in a state of deep purposelessness and, at some level and to some degree, seeks to will meaning into being through their actions. This is part of why so many of them engage in acts of abstruse symbolism and wrap their politically-incoherent violence in layers of iconography; they are engaged in cargo cult meaning-making, the pursuit of a pseudo-religion. The tail wags the dog; acts we have grown to see as expressions of meaning are in fact childish attempts to will meaning into being through violence.

25% of working age Brits are out of work

October 5th, 2025

In the United Kingdom, one-quarter of the working-age population is currently out of work:

(For comparison, in the United States, a similar statistic finds that only 16.6 percent of people in prime working ages are out of the labor force.) Once someone becomes economically inactive due to health reasons, their chances of ever reentering employment within a year drop to 3.8 percent. Up to 3,000 new people per day are writing off work and being approved for sickness benefits, now totaling around 4 million people.

[…]

A National Health Service (NHS) Confederation report showed that in 2021–22, over 63,000 people went straight from studying to being economically inactive due to long-term sickness. In 2002, mental and behavioral problems were the main condition for 25 percent of claimants. In 2024, that figure rose to 44 percent. More than half of the rise in disability claims since 2019 was due to mental health or behavioral conditions, according to the Institute for Fiscal Studies.

[…]

About 69 percent of those who apply for sickness benefits mention depression, anxiety, or some other kind of mental or behavioral disorder. Mental illness is now being cited by 48 percent of disabled working Brits, making mental health the single biggest problem.

[…]

According to data collected by the TaxPayers’ Alliance, a total of 1.75 million people in England received enhanced personal independence payments (PIP) in April 2025, an increase from 734,136 in January 2019. PIP is just one of many types of social security available to working-age claimants, intended to help them deal with the extra costs of disability. It is available to those in work. However, only one-sixth of PIP recipients are working. Some are receiving these benefits for seemingly minor ailments, including acne, constipation, obesity, “old age,” irritable bowel syndrome, writer’s cramp, and food intolerances.

[…]

In 2019, the number of PIP claimants for autism was 26,256, and by April 2025, this number had jumped to 114,211. For anxiety and depression, it went from 23,647 in 2019, to 110,075 in April 2025. For ADHD, in the same period, it went from 4,233 to 37,339.

[…]

As ludicrous as this sounds, approximately 80 percent of PIP claimants are not in work at all. A person getting incapacity benefits and PIP could be getting 23,899 pounds (roughly $32,250), which is already more than the minimum wage. Someone with children is entitled to even more. When PIP is combined with housing benefits, universal credit, and other offerings, someone could be entitled to 27,354 pounds (roughly $37,000) without paying taxes.
