Study argues that differences in how their brains are organized suggest that birds and mammals evolved intelligence independently. Makes sense, I mean, their last common ancestor was lizard.

Wealth and Gender Differences

Major meta-study finds that, in general, gender differences in psychology and life goals are greater in rich nations than poor ones, but on the other hand some particular differences decline with wealth. Abstract:

Some studies show that living conditions, such as economy, gender equality, and education, are associated with the magnitude of psychological sex differences. We systematically and quantitatively reviewed 54 articles and conducted new analyses on 27 meta-analyses and large-scale studies to investigate the association between living conditions and psychological sex differences. We found that sex differences in personality, verbal abilities, episodic memory, and negative emotions are more pronounced in countries with higher living conditions. In contrast, sex differences in sexual behavior, partner preferences, and math are smaller in countries with higher living conditions. We also observed that economic indicators of living conditions, such as gross domestic product, are most sensitive in predicting the magnitude of sex differences. Taken together, results indicate that more sex differences are larger, rather than smaller, in countries with higher living conditions. It should therefore be expected that the magnitude of most psychological sex differences will remain unchanged or become more pronounced with improvements in living conditions, such as economy, gender equality, and education.

The Musk Family's Hereditary Madness

Walter Isaacson's biography of Elon Musk has this on his father, who went crazy in his 40s:

One day [Musk’s cousin] Peter came over to the house and found Errol sitting in his underwear at the kitchen table with a plastic roulette wheel. He was trying to see whether microwaves could affect it. He would spin the wheel, mark down the result, then spin it and put it in a microwave oven and record the result. “It was nuts”, Peter says. Errol had become convinced that he could find a system for beating the game. He dragged Elon to the Pretoria casino many times, dressing him up so that he looked older than sixteen, and had him write down the numbers while Errol used a calculator hidden under a betting card.

Elon went to the library and read a few books on roulette and even wrote a roulette simulation program on his computer. He then tried to convince his father that none of his schemes would work. But Errol believed that he had found a deeper truth about probability and, as he later described it to me, an “almost total solution to what is called randomness.” When I asked him to explain it, he said, “There are no ‘random events’ or ‘chance.’ All events follow the Fibonacci Sequence, like the Mandelbrot Set. I went on to discover the relationship between ‘chance’ and the Fibonacci Sequence. This is the subject for a scientific paper. If I share it, all activities relying on ‘chance’ will be ruined, so I am in doubt as to doing that.”

I’m not quite sure what all that means. Neither is Elon: “I don’t know how he went from being great at engineering to believing in witchcraft. But he somehow made that evolution.” Errol can be very forceful and occasionally convincing. “He changes reality around him”, Kimbal says. “He will literally make up things, but he actually believes his own false reality.”

Among the other symptoms of Errol's madness were falling into conspiracy theories, believing that Trump won the 2020 election, praising Vladimir Putin, and going off on racist rants.

Fascinating. I have found Walter Isaacson to be a very reliable writer, and I think we can believe him. So maybe Elon's crackup is a hereditary problem, although all that ketamine and testerone can't help. (Of course maybe he went a little crazy, took ketamine for that, and ended up really crazy.)

I find myself wondering if Musk could ever have gotten funding for his ventures in the nineteenth century. I can imagine people like Gould or J.P. Morgan saying, "He seems brilliant, but you have to look at the family. Unreliable blood."

Falling Populations

The countries in red had more deaths than births in 2024.

Meanwhile in MAGAland

News from St. Paul:

A group of eight Republicans in the Minnesota House have introduced legislation (HF3219) that would designate certain vaccines and medical treatments as “weapons of mass destruction” and make possessing or administering them a crime punishable by up to 20 years in prison.

The legislation specifically targets messenger RNA (mRNA) treatments, which include several COVID-19 vaccines. Those vaccines have saved millions of lives and are considered one of the most important medical and public health achievements of the 21st century so far.

The bill’s language appears to have been drafted by Joseph Sansone, a Florida hypnotist and conspiracy theorist who believes that mRNA treatments are “nanoparticle injections” that amount to “biological and technological weapons of mass destruction.”

Sansone has falsely claimed that “more Americans have died from mRNA injections than in WWI, WWII, and the Vietnam War combined,” and has said he has stood “alongside an Army of the Dead” to file unsuccessful legal complaints against vaccines in Florida.

The bill has no chance of passage given the narrow margins in the House and Senate, as well as the DFL’s control of the governorship. But its support among multiple Republican representatives, including several members of GOP House leadership, give a sense of how the party would govern if it controlled the state legislature.

Bad as it is, it could get worse.

Meanwhile, at the Pro-Natalist Conference

This NY Times piece on the recent Natal Conference in Austin, by Emma Goldberg, is highly ironic and actually quite clever. Goldberg avoids doing the thing that makes so much reporting by liberals unreadable, that is, dismissing whole movements because some of their members are obnoxious racists. She found all sorts of people at the conference, including white nationalists but also tech types and women with lots of children just looking to connect with people like themselves. One woman said she had attended because “I knew having five kids wouldn’t make me the weirdest person in the room.”

Here's one good bit; when economist Bryan Caplan was challenged on how few women were among the speakers, he said,

“We were going to have more women. But they all got pregnant.” (He meant this literally; the conference organizers said four female speakers had dropped out, citing either pregnancy or caring for a sick child.)

The key observation is that while the mostly male attendees all think it is important to get women to have more babies, none of them have a clue how to do that. And so far as I can tell, the only answer anyone has found is “patriarchal religious cultism,” which I doubt will be successful on a large scale anywhere.

What struck me most was the sense many attendees had that having lots of kids makes you weird:

“If you want to have babies, go girl boss that,” said Hannah Centers, 41, a mother from Tennessee who home-schools her three children and said she felt judged by her neighbors when she told them she was pregnant with her third.

I have more children than any of my close friends, but if they think my family is weird, they are careful not to say anything in front of me. In fact I cannot remember ever feeling judged or shamed about my family. Some people clearly think it is crazy, but in the spirit of thinking people are crazy for being into ice climbing. So I'm not sure if people really are judging these mothers, or if maybe they are just insecure and seeing judgment where there is only bemusement. 

Ross Douthat on the new Age of Extinction

In the NY Times:

Every great technological change has a destructive shadow, whose depths swallow ways of life the new order renders obsolete. But the age of digital revolution — the time of the internet and the smartphone and the incipient era of artificial intelligence — threatens an especially comprehensive cull. It’s forcing the human race into what evolutionary biologists call a “bottleneck” — a period of rapid pressure that threatens cultures, customs and peoples with extinction.

When college students struggle to read passages longer than a phone-size paragraph and Hollywood struggles to compete with YouTube and TikTok, that’s the bottleneck putting the squeeze on traditional artistic forms like novels and movies. . . .

When young people don’t date or marry or start families, that’s the bottleneck coming for the most basic human institutions of all.

And when, because people don’t pair off and reproduce, nations age and diminish and die away, when depopulation sweeps East Asia and Latin America and Europe, as it will — that’s the last squeeze, the tightest part of the bottleneck, the literal die-off. . . .

This isn’t just a normal churn where travel agencies go out of business or Netflix replaces the VCR. Everything that we take for granted is entering into the bottleneck. And for anything that you care about — from your nation to your worldview to your favorite art form to your family — the key challenge of the 21st century is making sure that it’s still there on the other side.

That challenge is made more complex by the fact that much of this extinction will seem voluntary. In a normal evolutionary bottleneck, the goal is surviving some immediate physical threat — a plague or famine, an earthquake, flood or meteor strike. The bottleneck of the digital age is different: The new era is killing us softly, by drawing people out of the real and into the virtual, distracting us from the activities that sustain ordinary life, and finally making existence at a human scale seem obsolete.

In this environment, survival will depend on intentionality and intensity. Any aspect of human culture that people assume gets transmitted automatically, without too much conscious deliberation, is what online slang calls NGMI — not going to make it.

Languages will disappear, churches will perish, political ideas will evanesce, art forms will vanish, the capacity to read and write and figure mathematically will wither, and the reproduction of the species will fail — except among people who are deliberate and self-conscious and a little bit fanatical about ensuring that the things they love are carried forward.

Interesting, but I think this is a minor challenge compared to what happens when AI-powered robots can do literally everything better than we can. I am also not especially worried that humanity will go extinct. A transition to a much smaller population, as in Korea, will be hard, but for most of our history there were only a few hundred million of us and we did fine.

Maenads

Santo Stefano degli Abissini

Santo Stefano degli Abissini, Rome

In Vatican City, right behind St. Peter's, is a small church. The current facade dates to around 1700, but the Romanesque stonework around the door hints that this is a much older building. The first church here was built around 450 by Pope Leo I, and it evolved over the years into the modern structure. This is Santo Stefano degli Abissini, St. Stephen of the Ethiopians.

The existence of this church in such a prominent location, and its survival when most of the Vatican was rebuilt in the 1500s, hints at a mostly forgotten bit of history: the Papacy's determination to make allies of Christian Ethiopians, and their welcoming of a small community of Ethiopian monks within the walls of their city.

The sixteenth-century papacy was besieged on several fronts: the expansion of the Ottoman Empire, the Protestant revolt, growing nationalism in France, and the huge power of the Hapsburgs' globe-spanning empire; Spanish determination to dominate Rome led to their troops sacking the Eternal City in 1527. One of the ways the Popes sought to reassert their power was through scholarship; another was by seeking allies across the globe. The ancient Christian kingdoms of Ethiopia were perfect partners for these initiatives. They might, at least in theory, outflank the Ottomans militarily, and their ancient monasteries maintained traditions of learning to which no one else in Europe had access.

The leading Ethiopian churchmen were not shunted aside but welcomed into the church's inmost councils:

After the death of Pope Paul III on 10 November 1549, the Sacred College of Cardinals of the Catholic Church entered an unprecedented two-month conclave. As the faithful waited, the secluded cardinals produced sixty inconclusive ballots. Their protracted deliberations reflected the divisions within the College, which encompassed disagreements over the response to the Protestant Reformation as well as rivalries between supporters of the Holy Roman Empire and the Kingdom of France. After five fruitless weeks, one participant reported in his diary that on 7 January, an agitated African emerged at the balcony of the Sistine Chapel and looked down upon the assembly, exclaiming, “Very Reverend Lords, the conclavists have shut the doors, and thus now you must either starve or arrive at a decision about choosing a pope!” For some of the gathered princes of the Church, the outburst was surely a shock. But for the Roman Curia, the interlocutor was a familiar figure: it was abba Täsfa Ṣeyon (1510–1553), the Ethiopian cleric also known as Pietro Abissino or Indiano. No interloper, he was a conclave sacrist, client of the deceased pope, and adviser to the Tridentine Catholic elite, and his proximity to Paul III was such that he attended the latter's funeral wearing the ceremonial black cloth reserved for the friends of the pontiff.

Church door, said to be unchanged since the 1200s.

Täsfa Ṣeyon was a fascinating character, and we know an amazing amount about him. From a courtly family, he went into exile around 1530 after getting caught up in one of Ethiopia's many wars, journeying first to Jerusalem and then to Rome. There he joined the small diaspora of Ethiopians centered on St. Stephen's and soon became their leading spirit. He was a remarkable linguist, working in Latin, Greek, Arabic, and multiple Ethiopian tongues; among his accomplishments was preparing the first New Testament in Ge'ez. He also translated Ethiopian texts into Latin, helping lay the foundations of serious European scholarship about Ethiopia. Among his friends was Leo Africanus, a Catholic convert born in Muslim Spain who wrote a famous Description of Africa (1526).

The connection between Rome and Ethiopia also had impacts in Ethiopia:

Ethiopian emperors were keen to acquire European were keen to acquire European goods, craftsmen and artists. And this exchange bore fruit: Portuguese musketmen fought alongside Ethipian armies and Ethiopian embassies graced European courts; Ethiopian monks attended the Council of Florence in 1441, and masterpieces of the Italian Renaissance made their way to the highlands of East Africa – one of the more impressive boasts in the autobiography of the sixteenth-century Ethiopian aristocrat Seme'on is of owning an icon pained by the Venetian painter Nicolo Brancaleon. (TLS 14 Feb. 2025)

I love these global connections, the people who moved huge distances and found ways to live in foreign lands, the friendships that grew up between people from very different lands.

The RFK Regime is Censoring Researchers Who Agree with Their Agenda

Kevin Hall:

After 21 years at my dream job, I’m very sad to announce my early retirement from the National Institutes of Health. My life’s work has been to scientifically study how our food environment affects what we eat, and how what we eat affects our physiology. Lately, I’ve focused on unravelling the reasons why diets high in ultra-processed food are linked to epidemic proportions of chronic diseases such as diabetes and obesity. Our research leads the world on this topic.

Given recent bipartisan goals to prevent diet-related chronic diseases, and new agency leadership professing to prioritize scientific investigation of ultra-processed foods, I had hoped to expand our research program with ambitious plans to more rapidly and efficiently determine how our food is likely making Americans chronically sick.

Unfortunately, recent events have made me question whether NIH continues to be a place where I can freely conduct unbiased science. Specifically, I experienced censorship in the reporting of our research because of agency concerns that it did not appear to fully support preconceived narratives of my agency’s leadership about ultra-processed food addiction.

I was hoping this was an aberration. So, weeks ago I wrote to my agency’s leadership expressing my concerns and requested time to discuss these issues, but I never received a response. Without any reassurance there wouldn’t be continued censorship or meddling in our research, I felt compelled to accept early retirement to preserve health insurance for my family. (Resigning later in protest of any future meddling or censorship would result in losing that benefit.) Due to very tight deadlines to make this decision, I don’t yet have plans for my future career.

Harvard Defies Trump

Letter from President Alan Graber:

Late Friday night, the administration issued an updated and expanded list of demands, warning that Harvard must comply if we intend to “maintain [our] financial relationship with the federal government.” It makes clear that the intention is not to work with us to address antisemitism in a cooperative and constructive manner. Although some of the demands outlined by the government are aimed at combating antisemitism, the majority represent direct governmental regulation of the “intellectual conditions” at Harvard.

I encourage you to read the letter to gain a fuller understanding of the unprecedented demands being made by the federal government to control the Harvard community. They include requirements to “audit” the viewpoints of our student body, faculty, staff, and to “reduc[e] the power” of certain students, faculty, and administrators targeted because of their ideological views. We have informed the administration through our legal counsel that we will not accept their proposed agreement. The University will not surrender its independence or relinquish its constitutional rights.

The administration’s prescription goes beyond the power of the federal government. It violates Harvard’s First Amendment rights and exceeds the statutory limits of the government’s authority under Title VI. And it threatens our values as a private institution devoted to the pursuit, production, and dissemination of knowledge. No government—regardless of which party is in power—should dictate what private universities can teach, whom they can admit and hire, and which areas of study and inquiry they can pursue.

Our motto—Veritas, or truth—guides us as we navigate the challenging path ahead. Seeking truth is a journey without end. It requires us to be open to new information and different perspectives, to subject our beliefs to ongoing scrutiny, and to be ready to change our minds. It compels us to take up the difficult work of acknowledging our flaws so that we might realize the full promise of the University, especially when that promise is threatened.

We have made it abundantly clear that we do not take lightly our moral duty to fight antisemitism. . . .

These ends will not be achieved by assertions of power, unmoored from the law, to control teaching and learning at Harvard and to dictate how we operate. The work of addressing our shortcomings, fulfilling our commitments, and embodying our values is ours to define and undertake as a community. Freedom of thought and inquiry, along with the government’s longstanding commitment to respect and protect it, has enabled universities to contribute in vital ways to a free society and to healthier, more prosperous lives for people everywhere. All of us share a stake in safeguarding that freedom. We proceed now, as always, with the conviction that the fearless and unfettered pursuit of truth liberates humanity—and with faith in the enduring promise that America’s colleges and universities hold for our country and our world.

Empathy and Tarriffs

Balaji on Twitter/X, via Marginal Revolution:

Basically, American wokes weaponized shame and empathy. You were supposed to feel shame simply for being a man. To feel empathy for violent criminals. And so on.

So, the American right stopped listening. And stopped feeling shame or empathy. Especially for those outside the tribe.

But that was an overreaction too. Because most non-Americans are really not enemies. They're just neutral or even friendly business partners.

And without empathy for their position, for the very real costs these sudden random illogical tariffs imposed on them, the American right won't understand what comes next.

For example, they won't understand why the 190+ countries attacked via the tariffs aren't going to leap to America's side vs China. Quite the contrary.

And they won't understand why the tariffs are more like lose/lose than win/lose let alone win/win, because the US will face shortages of machine tools, medical supplies, and perhaps even food if they continue.

Anyway. Without understanding another man's negotiating position, without walking a mile in his shoes and thinking about how he can benefit too, you can't get to a win/win deal. That's why empathy is valuable even for cold-blooded capitalists.

The Ongoing Mystery of ADHD and its Treatment

Good NY Times piece today by Paul Tough on the controversy surrouding ADHD and its treatment with stimulants. It begins with James Swanson, one of the early experts on the problem and one of the first to experiment with giving stimulants to patients. In the mid 1990s, he was part of a major, NIH-funded study:

Swanson was in charge of the site in Orange County, Calif. He recruited and selected about 100 children with A.D.H.D. symptoms, all from 7 to 9 years old. They were divided into treatment groups — some were given regular doses of Ritalin, some were given high-quality behavioral training, some were given a combination and the remainder, a comparison group, were left alone to figure out their own treatment. The same thing happened at five other sites across the continent. Known as the Multimodal Treatment of Attention Deficit Hyperactivity Disorder Study, or M.T.A., it was one of the largest studies ever undertaken of the long-term effects of any psychiatric medication.

The initial results of the M.T.A. study, published in 1999, underscored the case for stimulant medication. After 14 months of treatment, the children who took Ritalin every day had significantly fewer symptoms than the ones who received only behavioral training. Word went out to clinics and pediatricians’ offices around the country: Ritalin worked. . . .

Though Swanson had welcomed that initial increase in the diagnosis rate, he expected it to plateau at 3 percent. Instead, it kept rising, hitting 5.5 percent of American children in 1997, then 6.6 percent in 2000. As time passed, Swanson began to grow uneasy. He and his colleagues were continuing to follow the almost 600 children in the M.T.A. study, and by the mid-2000s, they realized that the new data they were collecting was telling a different — and less hopeful — story than the one they initially reported. It was still true that after 14 months of treatment, the children taking Ritalin behaved better than those in the other groups. But by 36 months, that advantage had faded completely, and children in every group, including the comparison group, displayed exactly the same level of symptoms. Swanson is now 80 and close to the end of his career, and when he talks about his life’s work, he sounds troubled — not just about the M.T.A. results but about the state of the A.D.H.D. field in general. “There are things about the way we do this work,” he told me, “that just are definitely wrong.”

This exactly matches our experience in this house. Our eldest son is a classic ADHD case – and since we have two other sons, we know the difference between that and normal boyishness. We put him on Ritalin for a while, and he showed immediate changes: he did better in school, started reading books, bothered his siblings less. At first he was excited about this, but after some time – a couple of months, maybe? – he started to complain that he didn't like the way the meds made him feel, so we took him off them. After that we left the decision about taking them entirely up to him, and he used them on and off over the next few years, we think taking them when he got anxious about his grades. 

As I have written here many times, I think the human quest for drugs that change how we feel is ancient and unending, and that this says something important about how evolution has shaped us. It presumably also says something important about our society, in which the ability to sit still and concentrate on demanding work is very highly valued. So in principle I see nothing wrong with drugs that help some people sit still and concentrate. But I do not think we really understand what we are doing, or what the long-term consequences might be. So I very much appreciated this, from British neuroscientist Edmund Sonuga-Barke, who says that so far as he can tell "people with ADHD" is not a real category with definable boundaries:

I’ve invested 35 years of my life trying to identify the causes of A.D.H.D., and somehow we seem to be farther away from our goal than we were when we started. We have a clinical definition of A.D.H.D. that is increasingly unanchored from what we’re finding in our science.

Tough's piece covers many of the current controversies including whether ADHD patients should be sorted into different groups that are treated differently, whether the medications have unpleasant side effects, and whether the real answer is to let kids study what interests them. I recommend it. For me it strongly reinforced my basic assumption about all psychological issues, that you should never trust anyone who claims to have the answers.

Who Wants to Work in a Factory?

NY Times reporter Eduardo Medina went to South Carolina to get some straight talk about manufacturing in America:

In the 1970s, when the Upstate region of South Carolina was known as the textile capital of the world, Adolphus Jones would clock in for grueling summer shifts at one of the many mills in Union, his hometown.

Trains roared around him, transporting materials around the country. Chimney stacks on the red brick mills stretched dozens of feet high, like flag poles. This was textile country, and the cities of Union, Spartanburg and Greenville were at the heart of it.

By the end of the 1990s, automation and cheaper labor overseas took the industry away from the state. Union’s economy cratered, as did most of the region’s. But leaving Sunday church service on a recent afternoon, Mr. Jones, now 71 and retired, scoffed at President Trump’s vision of an American manufacturing revival through tariffs. The mill work had paid little, Mr. Jones recalled, and upward mobility was nonexistent.

“The textile industry is dead,” he said, buttoning his wool suit made in Italy. “Why would you want to bring it back here? Truthfully, why would the younger generation want to work there?”

Many retirees still remember what it was like to work in the textile mills. It had a negative connotation, said Rosemary Rice, 70, with some workers derogatively called “lint heads” because they would come home covered in cotton shreds. Many developed “brown lung disease,” or byssinosis, a respiratory condition caused by ingesting dust particles from fabric materials.

“I wouldn’t want my son working there,” said Ms. Rice, who lives in Union.

Actually, there is one group of Americans who might want tough, badly-paid factory work: recent immigrants. Let's look back to the cat-eating Haitians of Springfield, Ohio, about whom the factory owner said, 

I was I had thirty more. Our Haitian associates come to work every day. They don't have a drug problem. They will stay at their machine. They will achieve their numbers. They are here to work. And so, in general, that's a stark difference from what we're used to in our community.

So, you know, if Trump is serious about bringing back textile and other low-end manufacturing, he should open the borders. I imagine the irony of this would be lost on him.

Not, of course, that manufacturing is disappearing from America. Most of it is kind that doesn't use many workers, like chemicals, but some of it does. Like assembling cars:

Today, companies like BMW and Michelin — from Germany and France — are the economic engines of the region. Since BMW opened its plant in Spartanburg County in the early ’90s, it has invested more than $14.8 billion into its South Carolina operations. The plant has more than 11,000 jobs, its largest single production facility in the world, according to the company. And it is the country’s largest car exporter by value, with $10 billion in shipments last year.

So the local business community was stunned when the White House’s top trade adviser, Peter Navarro, attacked BMW’s manufacturing process in an interview this week. He told CNBC on Monday that “this business model where BMW and Mercedes come into Spartanburg, S.C., and have us assemble German engines and Austrian transmissions — that doesn’t work for America. It’s bad for our economics. It’s bad for our national security.”

“There was widespread bewilderment in our community about that,” said Carlos Phillips, the president and chief executive of the Greenville Chamber of Commerce.

In response to Mr. Navarro’s comments, South Carolina’s governor, Henry McMaster, told reporters this week that ever since BMW arrived in the state with well-paying jobs, other companies had followed suit and “sent the word out around the world that this is a great manufacturing state.”

So the Trump team wants manufacturing, except not the kind that actually takes place in the US.

Speaking of which, Trump has also launched a savage assault on a big category of successful American exporters: defense firms. Spooked by Trump's erratic, pro-Putin stance, European countries have already cancelled billions of dollars worth of orders for US fighter jets and other weapons and launched a major initiative to produce more of their weaponry in Europe.

Which pretty much sums up the problem with MAGA politics: the denial that there is a world out there, full of people and nations with their own agendas who will not simply roll over and do whatever it is that Trump & Co. fantasize they should do. The world is complicated, and all the evidence to date is  that MAGA is too simple-minded a movement to grapple with it successfully.

Heather Fawcett, "Emily Wilde's Encyclopedia of Faeries"

I listened to this book on my way home from my latest round of fieldwork, and it brightened a long, weary drive through rain and heavy traffic. It is 1910, more or less, and Emily Wilde is a Cambridge scholar of faerie lore in a world where faeries are real. She falls into faeryland adventures, as she must, and emerges intact largely because her great knowledge of faerie stories tells her how to handle every situation.

This ties into what is of course an old fantasy of mine, that if I were somehow transported to a world with magic based on the traditions of old Europe, I would be a force to be reckoned with.

Also, of course, our heroine acquires a faerie lover, because for a certain sort of (mostly female) author, romance with a faerie lord/vampire/werewolf/dragon/generic magical being is an essential part of the fantasy. This gives me a chance to wonder why this is not true for me.

I commented on this when I reviewed E.T.A. Hoffmann's Tales, that in the story where the main character chooses the daughter of the King of Salamanders over a mortal woman, I found the mortal woman more appealing. The mountain of superlatives heaped on the beauty and charm of the otherwordly woman did not move me. 

I have considered various complex and arcane explanations for this, but I think it actually simple: for me the erotic is not about escaping from earthly, physical, bodily life, but reveling in it. And I don't mean just sexually; the most romantic thing I have ever done is have babies, which is as profoundly earthly and physical an experience as one can have.

Dream/Metaphor

Last week I had a dream from which I woke trembling. I was playing a big table-top strategy game with three other people. I was pretending to be much more expert at this game than I actually was. I moved a stack of counters across the board and placed them on a city hex to lay siege to it. Then I reached for the small laminated card that had the die roll results for sieges.

When I reached for it, the card was only a little larger than a standard playing card. But as I searched it for the table I needed, it grew. First it grew to an 8.5x11 sheet. Then to 11x17. Then there was more writing on the back. As I continued frantically searching the card for the right table I was aware that everyone was watching me and noting my inability to find this simple thing. But the thing in my hands kept growing until it was a like an old-fashioned folded road map, and I kept unfolding it and turning it over, growing ever more desperate, until I woke in panic.

Obviously this is a metaphor for something, but I am not sure it if is life in general or just the crazy stuff I have been going through at work lately.

Why is Modernism Still Cool?

There is a web site called The Cool Hunter. They feature a variety of different styles in art and design, but only one kind of architecture: modernism. The modernist tree house above was on their front page just a minute ago when I went to check.

Is the music of the 1950s cool? the clothes? the movies? No.

So why is architecture of the 1950s still cool?

For at least the past 400 years, the styles favored by the elite have varied. Many critics have said that they change because of a cycle of innovation and immitation. The rich, stylish people on the cutting edge adopt a new style because it sets them apart. But then everyone else starts to immitate them, and within a few years what once distinguished the rich and stylish is now being worn by everyone. The rich and stylish therefore move onto something else, and look with horror on what they enjoyed a few years ago.

Then the rich and stylish fell for modern architecture. One might expect that soon everyone else would fall for it and then the rich and stylish would move on to something else. That didn't happen, because everyone not in the narrow world of the rich and stylish hated modern architecture and still hates it. So a fondness for it never spread. The rich and stylish found that in this one area they did not need to keep adopting new styles to distinguish themselves from the masses. They could just keep extolling modernism, because everybody else hated it so much.

Seen this way, it is not mysterious that elite architects and the billionaires who hire them stick with modernism. The more the masses hate it, the easier it is to signal that your are not a peasant by building something modern, preferable with at least a hint of brutalism. So we have ended up in this weird place where the famous architects are all modernists and the public rages against their awful creations, but the rich keep hiring them precisely because the masses hate their creations so much. Q.E.D.

Rand Paul Takes on the Tyrant

Rand Paul on the Senate floor:

Taxation without representation is tyranny, bellowed James Otis in the days and weeks leading up to the American Revolution. This became the rallying cry of American patriots. . . . Our founding fathers believed so strongly in this that they embodied in our Constitution. Our Constitution doesn't allow any one man or woman to raise taxes. It must be the body of Congress. And this wasn't new; it was part of maybe a thousand-year tradition from Magna Carta on. . . . This principle was long-standing, it was non-negotiable; this was what sparked the Revolution.

And yet today we are here before the Senate because one person in our country wishes to raise taxes. This is contrary to everything our country was founded upon. One person is not allowed to raise taxes. The constitution forbids it. . . . Forty, fifty years before our Constitution, Montesquieu wrote, "when the executive and legislative powers are united in one person, there can be no liberty." Our founding fathers took this to heart. They said, we must separate the powers, we must at all costs limit the powers of the presidency. This isn't about political parties. I voted for and supported President Trump, but I don't support the rule of one person. We are set to have a 25% tax on goods coming from Canada and Mexico. This is a tax on the American people, plain and simple. One person can't do that. Our founding fathers said no, that would be illegal. It can't come from one person. It has to come to Congress.

You can't simply declare an emergency and say, well, the Constitutional Republic was great but gosh we've got an emergency, our times are dire. The Supreme Court has repeatedly said, there are no exemptions for emergencies. There was no exemption for a pandemic. The taxation clause stands. . . .

[after trashing the excuse of fentanyl as an "emergency," Rand said]

Even if the problem is valid, even if that is something that we all agree on, you can't have a country ruled by emergency. You can't have a country without a separation of powers, without checks and balances. . . . Part of the problem we face today with this emergency is that Congress has abdicated their power. Not just recently, not just for this president. This is a bipartisan problem. . . . I am a Republican, I am a supporter of Donald Trump, but this is a bipartisan problem. I don't care if the president is a Republican or a Democrat; I don't want to live under emergency rule. I don't want to live where my representatives cannot speak for me.

One person can make a mistake; and guess what, tariffs are a terrible mistake. They don't work, they will lead to higher prices, they are a tax, and they have historically been bad for our economy. But even if this was something magic and it was going to be a pot of gold at the end of the rainbow, I wouldn't want to live under emergency rule. I would want to live in a constitutional republic where there are checks and balances against the excesses of both sides, right or left. If one person rules, that person could make a horrible mistake. . . .

The emergency declaration we are considering today is unprecedented. By declaring an emergency, the president invoked the Internation Emergency Economic Powers Act. . .  It's a law that has been used to put sanctions on like Iran. That's what it was intended for. It was never intended for tariffs and the word tariff doesn't appear in the law. Using this bill to impose tariffs is attractive to a president. He doesn't have to work with the messiness of democracy, the messiness of Congress. But you know what; that messiness is a check and a balance on power. . . . Expedience is not the same as legality. 

This is not a partisan question. To me it makes no difference if the president is a Republican or a Democrat. This is about the distribution of power. This is about the separation of powers. This is about the admonition that Montesquieu gave us, that when the executive power and the legislative power are united in one person, there can be no liberty. Our founding fathers all believed that. They so feared the power of taxation that they gave it only to Congress. . . . This goes against the traditions of our country.

I stand to speak against these tariffs. I stand to speak against these emergencies. I stand against the idea of skipping democracy, of skipping the constitutional republic, of rejecting our founding principles. Not because I have any animus toward the president. I do this because I love my country and I want to see it protected from the amalgamation of power into one person so that it can be abused.

Another name for emergency rule is martial law. Who would want to live under the rule of one person? The thing we object to in all the countries around the world that we dislike is that they don't have democratic rule. We should vote. This is a tax, plain and simple, and taxes should not be enacted by one person. I will vote today to end the emergency. I will vote to day to try to reclaim the power of taxation to where the constution designated it should properly be, and that is in Congress.

Dire Wolves?

Colossal Biosciences, which spent years trying and failing to bring back the woolly mammoth, now claims to have brought back the dire wolf. (NY Times, Time, company post on Twitter/X with wolf pup howls)

Sort of. What they did was find some dire wolf DNA, identify 22 places on the genome where they differed from modern gray wolves, alter those locations to be like their dire wolves, insert that DNA in a gray wolf egg cell and have it carried to term by a wolf.

The offspring are different from modern wolves, bigger and with paler, thicker fur. So they are something different from modern wolves. But I am not willing to call them dire wolves.

Still, this is pretty cool, the biggest step yet in the de-extinction program. But note that dire wolves were so closely related to gray wolves that they seem to have interbred with them in the past. Nothing about this success says we might be close to bringing back animals without such a close living relative.

Fernanda Melchor, "Hurricane Season"

The amazing thing about Hurricane Season (2017, English translation 2020) is its frantic energy, an electrical storm of words, images and emotions. In a poor part of rural Mexico, a strange character known only as The Witch is murdered. The story is told from the perspectives of four characters, two male and two female, all with their own passions and their own hatreds, their own vocabularies of abuse that they direct at the world around them. In particularly they despise and abuse the opposite sex. The crimes here are all sex crimes, in a broad sense: they are about gender relations, male attempts to control women, female attempts to get something from men, straight scorn for homosexuality, and the rage of men whose machismo is threatened. In one sense it is an indictment of male misdeeds, but it is not preachy; it just turns its electric gaze on awful things, lighting up the horror and the pain of those acts like it lights up everything about its characters' worlds.

I don't recommend it for everyone. It is obscene, profane, confusing, and sometimes grim, but it is the least boring book I have listened to in years.

The Decline of the Book, and What Might Replace it.

Interesting musings from Sam Kahn about the decline of the book as a form, and what might replace it. After referencing the various doomsters who say that today's college students are functionally illiterate and so on, he notes that while books may be in trouble, "writing is undergoing a renaissance."

But if print can survive the flood — through articles, short-form writing, etc — books may still find themselves a casualty. In part, what the doomsaying articles are saying about students is not necessarily that they can’t read but that they can’t read long-form work. And to some extent the kids may have a point. It is a crowded marketplace out there; the more time you spend with one person means time taken away from others. And, by the same token, if so many people are so adept at saying what they have to say in short-form writing, why the need for a doorstop? Part of what the kids may be intuiting is that a book needs to be of a certain length in order to justify the cost of the binding — and writers writing books tend, even at the conceptual level, to pad out, trying in their minds to be worthy of the majesty in the implicit idea of a book. But readers’ behavior in the digital era is very different. They are not looking to fill out a train ride or long winter’s evening with a book. They are reading looking for an idea, for something interesting, and what that implies is that writers can use readers’ attention spans, rather than the imagined length of a book, in order to give shape to their ideas. A text should be as long as it takes to express the idea.

I agree with this completely. The world is full of books that should have been articles or short stories, padded out to 250 pages because that is what the publishing world requires. Even writers as well known as Kazuo Ishiguro do this, turning interesting little ideas into bloated "books."

What I would expect that means in the realm of serious writing is, over the next years, a good deal of structural innovation in text. Even in a domain like biography or history, where the book seems especially sturdy as a form, I notice writers chafing under its inherent limits. Why should biographers have to devote the precious real estate at the beginning of their book to discussing their subject’s grandparents while the subject’s main accomplishments often come somewhere towards the end when reader and writer are both exhausted? The ‘archipelago’ may be a more simpatico structure for history than the straight line. One can only imagine how much smoother poor Robert Caro’s life would have been if he could have started with the presidency of his subject as opposed to spending forty years chasing down the truth of Lyndon Johnson’s student council experiences and then waiting until his 80s to write down the meat of his project. In fiction, I would imagine writers gravitating towards the novella (an excellent form that fell into disuse because it didn’t quite fit the exigencies of the publishing industry) and maybe on the more innovative, ambitious side we can imagine writers using the resources of the web to produce sprawling fictive worlds that don’t necessarily have to be connected by a throughline.

Reading this I imagined turning my old gaming world into a sort of hypertext story in which you could switch between cities and region and follow different characters and see both how the main events transpire or are reflected in every region, plus the local concerns of each. Imagine this for LOTR, an edifice within which the sort of nerds who write posts about "what was really happening in Umbar" can go read about it. George R.R. Martin might have loved this.

I like reading novels; it is a form I enjoy. I have also enjoyed writing them. But I do suspect that they are not the future of storytelling. I suspect that while novels will endure for a long time, writing may evolve in diverse directions. Many stories will be shorter. Writers with longer stories to tell may split them into pieces; this already happens in collections of linked short stories, and we may get more of it. I can also imagine stories told like The Princess Bride, with the "good parts" narrated in detail and much of the rest just sketched out in little text or video interludes.

After saying a bit about how powerful he has found the experience of writing novels, Kahn notes that what writers find meaningful for themselves is not necessarily what the world wants:

I would say the intelligent thing to do here is is to try to change up our values system for the digital age. Good writing can be done in short chunks — articles, short stories, novellas, whatever — just as good running can be done at any length. Novels should probably be treated as what they are — something like a marathon, a sort of circus freak event for those who for some reason or other are determined to pursue that — as opposed to what they are now, which is like a badge of entry for writing. In other words, novels seem singularly unsuited to the digital era. That’s unfortunate but should be clarifying for those who write novels: that they are doing it more as a spiritual exercise than to reach an audience.

For now, this is still not true; there are still many millions of novel readers out there. But we are aging, and I consider it an open question how many of us there will be in future generations. Storytelling will always be with us, but the novel is an invention of certain cultures, and most of humanity always did perfectly well without it. 

Anti-Bullying and the Rise of MAGA

I have long been interested both in the phenomenon of bullying and the role of the anti-bullying movement in the modern left. (Just type "bullying" into the search bar on this blog and you'll see what I mean.) I think anti-bullying movement is a great way to understand modern left-liberals and the ways they want to change the world.

On the one hand, bullying is bad; there is now a lot of data showing that bullying scars many people for life, leading to their having shorter lives, lower incomes, and so on, plus it just sucks to be bullied. We have seen many organizations torn apart by accusations of bullying and mistreatment. So doing what we can to limit bullying seems to me like a good idea.

On the other hand, this can be taken too far, leading to absurdities like not letting children play games in which one side wins, and bans on using words like "fat" or "stupid." At the far end of this we have seen some adults trying to keep children from forming close friendship pairs, because this might leave somebody out.

Watching MAGA in power, I keep wondering if this is the key to the contemporary political landscape. People sometimes say that Trump's appeal is "just racism," but to me that leaves a huge amount unexplained (including his appeal to non-white voters). Does it maybe make more sense to see MAGA as a defense of bullying? Or, less radically, as an attack on the apparatus liberals have put into place to prevent it? Or as a celebration of the tough characters who shove everyone else down on their way to the top?

The first point to notice is that from Trump on down, MAGA's leadership is full of bullies: Hegseth, Musk, Stephen Miller, etc. One of their battle cries seems to be, "Yes, we're assholes, and there's nothing you can do about it." In that sense MAGA is a direct reaction against the anti-bullying movement from people who think that we have too many weak pansies in the country and not enough toughness.

Consider "free speech." Some of the points where conservatives have shouted the loudest have to do with liberal attempts to ban speech we consider harmful, like sexist jokes. Against the sort of sweet liberal schoolmarm ethic of "we're nice all the time and nobody says anything bad to anybody," MAGA sets "real men need to be able to both dish it out and take it."

Anti-bullying is about being careful. Having been trained in this multiple times, I can tell you that the program is largely about thinking before you speak. Don't speak in anger. Limit your sarcasm. Tone down your criticism. Try to see every situation from everyone's point of view. Is that not the opposite of MAGA?

True, some MAGA people also seem to be thin-skinned and whiny when anybody criticizes them, but it is hardly news that many bullies are like that.

I don't want to seem cavalier about this; "MAGA is for bullies" may be true, but if so that simple statement may be short hand for a deeper sort of human division. MAGA people don't care about Ukraine because they don't want to hear from weaklings who can't defend themselves. Part of the appeal of RFK and his wacky medicine to MAGA is his insistence that being healthy is all up to you; you don't need doctors and hospitals and vaccine factories. MAGA people don't want to talk about complexity; their solutions are always simple and direct. Build a wall. Fire the bureaucrats.

One might define liberalism, in this context, as the belief that, no, actually, you don't stand alone, your whole exitence depends on unbelievably complicated systems and crazily huge bureaucracies, and taking care of those systems is a big part of why we have governments.

You don't have to tell me how hypocritical this is; I see it, too. But I do believe that the contrast between a sweet elementary school teacher who wants everyone to be kind and Donald Trump mocking female reporters for being fat and ugly says something important about the US today.

AI and the Future of Warfare

Long but very interesting interview with US defense official Michael Horowitz and Shashank Joshi, who is The Economist's defense reporter, about military AI. Here is Joshi on the range of possible applications:

We could split the applications of that general-purpose technology up a million different ways. The way I have tended to do it in my head is thinking about insight, autonomy, and decision support.

Insight is the intelligence application. Can you churn your way through satellite images? Can you use AI to spot all the Russian tanks?

Autonomy is, can you navigate from A to B? Can this platform do something itself with less or no human supervision or intervention? The paradigmatic case today, which is highly impactful, is terminal guidance using AI object recognition to circumvent electronic warfare in Ukraine.

The third interesting thing is decision support. This includes things that nobody really understands in the normal world, like command and control. It’s the ability of AI to organize, coordinate, and synchronize the business of warfare, whether that’s a kind of sensor-shooter network at the tactical level for a company or a battalion, or whether it’s a full theater-scale system of the kind that European Command, 18th Corps, and EUCOM has been assisting Ukraine with for the last three years.

This involves looking across the battlescape, fusing Russian phone records, overhead, radio frequency, satellite, IM satellite returns, synthetic aperture radar images, and all kinds of other things into a coherent picture that’s then used to guide commanders to act more quickly and effectively than the other side. That’s difficult to define. But if we’re talking about transformative applications, that is really where we need to be looking carefully.

Here is Horowitz on drone swarms:

If the question is “Where are the swarms we were promised?” and what we end up with is a world where one person is overseeing maybe 50 strike weapons that are autonomously piloting the last two kilometers toward a target, there may be actually military reasons why we don’t want them to communicate with each other. If they communicated with each other, that would be a signal that could be hacked or jammed, which then gets you back into the EW issue that you’re trying to avoid.

So maybe drone swarms as they exist now are not militarily relevant.

Never Satisfied

Augustus the Strong (1670-1733) was the Elector of Saxony, a nice enough position, effectively the independent ruler of a pleasant little kingdom. But it was not enough for him, so he accepted the throne of Poland-Lithuania. This embroiled him in no end of trouble. A French noble woman commented,

That the Elector of Saxony could not be satisifed with being an Elector only goes to show what I have long observed, that no one can be really happy in this world and everyone foolishly sets about throwing away his happiness, for this Elector would have been a thousand times happier if he had gone on enjoying a quiet and peaceful life as Elector of Saxony instead of becoming King of such a fractious nation.
