A sinister attractor – why men are more likely to be left-handed

Kevin Mitchell in Wiring the Brain:

It seems an innocent enough question: why are males more frequently left-handed than females? But the answer is far from simple, and it reveals fundamental principles of how our psychological and behavioural traits are encoded in our genomes, how variability in those traits arise, and how development is channelled towards specific outcomes. It turns out that the explanation rests on an underlying difference between males and females that has far-reaching consequences for all kinds of traits, including neurodevelopmental disorders.

recent tweet from Abdel Abdellaoui showed data on rates of left-handedness obtained from the UK Biobank, and asked two questions: why is left-handedness more common in males and why are rates of reported left-handedness increasing over time?

I don’t think the answer to the second question is known but I presume it has to do with the declining practice of forcing left-handers to write right-handed. This once common practice reflects a long history of prejudice against lefties, illustrated by the derivation of the word “sinister”, which in Latin means “left”, as opposed to “dexter” meaning “right” which is the root of the positive words “dexterity” and “dextrous”.

The first question – why is left-handedness more common in males? – is the one I want to explore here, as it opens up some fascinating questions about robustness, variability, and developmental attractors.

Conspiracy theories are extremely effective emotional tools

David Brooks in the New York Times:

For those awash in anxiety and alienation, who feel that everything is spinning out of control, conspiracy theories are extremely effective emotional tools. For those in low status groups, they provide a sense of superiority: I possess important information most people do not have. For those who feel powerless, they provide agency: I have the power to reject “experts” and expose hidden cabals. As Cass Sunstein of Harvard Law School points out, they provide liberation: If I imagine my foes are completely malevolent, then I can use any tactic I want.

Under Trump, the Republican identity is defined not by a set of policy beliefs but by a paranoid mind-set. He and his media allies simply ignore the rules of the epistemic regime and have set up a rival trolling regime. The internet is an ideal medium for untested information to get around traditional gatekeepers, but it is an accelerant of the paranoia, not its source. Distrust and precarity, caused by economic, cultural and spiritual threat, are the source.

What to do? You can’t argue people out of paranoia. If you try to point out factual errors, you only entrench false belief. The only solution is to reduce the distrust and anxiety that is the seedbed of this thinking. That can only be done first by contact, reducing the social chasm between the members of the epistemic regime and those who feel so alienated from it. And second, it can be done by policy, by making life more secure for those without a college degree.

On ‘There’s No Such Thing As An Easy Job’

Rebecca Liu at Prospect Magazine:

“God,” a friend of mine recently confided to me, “needs to make a comeback.”

She sounded like she was joking, she continued, but she wasn’t. Growing up in the overwhelmingly secularised milieu of millennial city-dwellers was not delivering her any meaning, particularly during the era of Covid-19. The already apparently trivial demands she faced daily at work seemed to not slow down, but rather accelerate. Her bosses were still urgently demanding her to work to an increasingly arbitrary schedule; clients still desperately needed action from her, today. At a time of mass suffering, there seemed little to reflect on how best to live.

The protagonist in Kikuko Tsumura’s There’s No Such Thing As An Easy Job, translated by Polly Barton (and the first of Tsumura’s novels to be translated into English), lives in a world bereft of meaning, flitting between—like my friend, like most of us—roles that promise us a respectable claim to adult life: jobs.

Remembering Jan Morris

The Editors at The Paris Review:

Wales mattered to Jan. In midlife, and at more or less the same time as her gender reassignment, she embraced what she called Welsh Republicanism. Her home, Trefan Morys, is in a remote area near the town of Criccieth. You leave the main road, take a long, rutted drive, negotiate the narrow entrance in a high stone wall, and you are suddenly in an enchanted space. Elizabeth was the architect of the garden and Jan the interior designer. You enter the house through a two-part stable door (Jan always greeting you with the words, “Not today, thank you”), into a cozy kitchen, and then the main downstairs room. The walls are lined with eight thousand books, including specially leather-bound editions of Jan’s own. Up the stairs there is another long room, with an old-fashioned stove in the middle. Here are more books, but this space is given over mainly to memorabilia and paintings. Pride of place is given to a six-foot-long painting of Venice, done by Jan, in which every detail of the miraculous city is rendered (including tiny portraits of the two eldest sons, who were very young at the time Jan painted it). Model ships hang from the ceiling, and paintings of ships adorn the walls. Jan loved ships from the time she spied them, as a child, through a telescope as they passed through the Bristol Channel near her family’s home.

NHS to trial blood test that can detect over 50 cancer types

From Medical Device Network:

The UK National Health Service (NHS) is set to initiate the trial of Galleri blood test that can potentially detect over 50 types of cancers. Developed by GRAIL, the test is capable of detecting early-stage cancers through a simple blood test. In research on patients with cancer signs, the test identified many types like head and neck, ovarian, pancreatic, oesophageal and some blood cancers, which are difficult to diagnose early. The blood test checks for molecular changes. NHS Chief Executive Simon Stevens said: “Early detection – particularly for hard-to-treat conditions like ovarian and pancreatic cancer – has the potential to save many lives. “This promising blood test could therefore be a game-changer in cancer care, helping thousands of more people to get successful treatment.” Anticipated to start in the middle of next year, the GRAIL pilot will involve 165,000 people. This participant population will include 140,000 people aged 50 to 79 years who have no symptoms but will have annual blood tests for three years.

Those tested positive will be referred for investigation in the NHS.

Furthermore, another 25,000 people with possible cancer symptoms will be offered testing to fast-track their diagnosis after being referred to a hospital in the normal way. The results of these studies should be available by 2023. On obtaining positive outcomes, the study will expand around one million participants in 2024 and 2025.

The Science Behind Dreaming

Sander van der Linden in Scientific American:

For centuries people have pondered the meaning of dreams. Early civilizations thought of dreams as a medium between our earthly world and that of the gods. In fact, the Greeks and Romans were convinced that dreams had certain prophetic powers. While there has always been a great interest in the interpretation of human dreams, it wasn’t until the end of the nineteenth century that Sigmund Freud and Carl Jung put forth some of the most widely-known modern theories of dreaming. Freud’s theory centred around the notion of repressed longing — the idea that dreaming allows us to sort through unresolved, repressed wishes. Carl Jung (who studied under Freud) also believed that dreams had psychological importance, but proposed different theories about their meaning.

Since then, technological advancements have allowed for the development of other theories. One prominent neurobiological theory of dreaming is the “activation-synthesis hypothesis,” which states that dreams don’t actually mean anything: they are merely electrical brain impulses that pull random thoughts and imagery from our memories. Humans, the theory goes, construct dream stories after they wake up, in a natural attempt to make sense of it all. Yet, given the vast documentation of realistic aspects to human dreaming as well as indirect experimental evidence that other mammals such as cats also dream, evolutionary psychologists have theorized that dreaming really does serve a purpose. In particular, the “threat simulation theory” suggests that dreaming should be seen as an ancient biological defence mechanism that provided an evolutionary advantage because of  its capacity to repeatedly simulate potential threatening events – enhancing the neuro-cognitive mechanisms required for efficient threat perception and avoidance.

So, over the years, numerous theories have been put forth in an attempt to illuminate the mystery behind human dreams, but, until recently, strong tangible evidence has remained largely elusive.

Friday Poem

Immigrant Confession

The Cherokee are not originally from Oklahoma. Settlers forced
them to disappear west, into air and sky, beyond buildings,
beyond concrete, beyond the rabid land hunger. There was
a trail. There was despair. Reservations carved out of prairie
grass, lost space and sadness in the middle of flat dirt. We landed
in March 1980. We knew nothing about the Cherokee.
Settlers from the South, driven by opportunities and education,
looking for the gold and gifts of immigration, we hid our Spanish,
the shame of accents and poverty, immersed ourselves in cowboy
ways. In school we learned English, read about open, endless
land, a territory there by divine right for those willing, chosen
to till and build, for those exiled, broken out of other lands.
Every spring the second grade celebrated the land rush. Half of us
immigrants flung across the globe, we wanted to be part of the story.
We gathered in costume behind the chalk line in a field across from
Westbury elementary. Girls in calico skirts, bonnets, ruffled blouses.
Boys in straw hats, borrowed cowboy boots, chaps strapped with toy guns.
Parents and picnic lunches waited on the sidelines. The cap gun popped.
The second grade scattered wild, stakes in hand running, ready to claim
our piece of promised land. My parents celebrated the land rush twice,
two of us old enough to live into the strange alchemy of assimilation.
I learned later our stakes professed death, bloodied limbs, hacked up
hearts, bodies crushed, taken from the arid land with the wave of a flag,
the pulsing stampede of wagons, the firing of the starting gun,
disappeared with every second-grade spring picnic.
Two million acres of territory taken in the first land rush.
My immigrant confession: I have ached for my Oklahoma childhood,
my territory story, when the land gave again, held a promise of country
after exile. I have mourned the second-grade land rush, the look on
my parents’ faces as we galloped into yellow grass, screaming breathless
in joy and wildness, when they imagined an America big enough,
wide enough, whole enough to let us in, whole enough not to break us.

The Substack Discourse and the Self-Referentiality of Everything

Justin E. H. Smith in his Substack Newsletter:

You might recall the strange case of Matthew J. Mayhew, professor of educational administration at The Ohio State University. In late September he published an opinion piece in Inside Higher Ed enumerating the many supposed virtues of college football. A week later he issued, in the same venue, an abject apology for his first piece, in which, he now confessed, he had failed to recognise the various ways his support for collegiate athletics perpetuated white supremacy and failed to center the voices of people of colour. “I am just beginning to understand,” he wrote, “how I have harmed communities of color with my words. I am learning that my words —my uninformed, careless words— often express an ideology wrought in whiteness and privilege.”

One could not help but try to imagine the struggle session to which Mayhew was subjected that week, from which he emerged as if reborn. It seems hard to deny that he is sincere in his follow-up piece —the common view that he is writing as if there is a gun held to his head misses the mark—, but also totally and radically converted from one way of seeing the world to another, a conversion that can typically only occur where there is significant social and institutional pressure.

How scientists developed the Oxford vaccine at breakneck speed

Ian Sample in The Guardian:

At the heart of Oxford’s effort to produce a Covid vaccine are half a dozen scientists who between them brought decades of experience to the challenge of designing, developing, manufacturing and trialling a safe vaccine at breakneck speed.

Prof Sarah Gilbert, the Kettering-born project leader, arrived at Oxford in 1994 to work with Prof Adrian Hill, a senior member of the team, on the malaria parasite, plasmodium. She soon fell into work on experimental vaccines, starting with one that roused white blood cells to fight malaria, followed by a “universal” flu vaccine.

As a student, Gilbert is said to have knitted cardigans with dogs on and played her saxophone in the woods to avoid disturbing her neighbours. As a researcher at Oxford, she gained a no-nonsense reputation, which some attribute in part to her raising triplets, though her husband gave up work to parent them.

Oxford’s coronavirus work built on research pioneered by Hill and Gilbert on vaccines based on a virus that causes common colds in chimpanzees.

The Plot and the Argument: Philosophy as a Narrative Affair

Costica Bradatan in the Los Angeles Review of Books:

“AND WHAT ABOUT unbiased research? What about pure knowledge?” bursts out the more idealistic of the two debaters. Before the other, the more cynical one, even has a chance to answer, the idealist ambushes him with even grander questions: “What about the truth, my dear sir, which is so intimately bound up with freedom, and its martyrs?” We can picture the caustic smile on the cynic’s face. “My good friend,” the cynic answers, “there is no such thing as pure knowledge.” His words come out calmly, fully formed, in sharp contrast to the idealist’s passionate, if sometimes logically disjointed pronouncements. The cynic’s rebuttal is merciless:

Faith is the vehicle of understanding, the intellect is secondary. Your unbiased science is a myth. Faith, a world view, an idea — in short, the will — is always present, and it is then reason’s task to examine and prove it. In the end we always come down to “quod erat demonstrandum.” The very notion of proof contains, psychologically speaking, a strong voluntaristic element.

To the idealist, brought up in the grand tradition of the European Enlightenment, this looks like a mockery of all he stands for. He can’t take the cynic’s reasoning other than as a tasteless joke.

Thanksgiving Day: How an ‘Indian bird’ made its way to the American dinner table

Vivek Menezes in Scroll.in:

Our quest centres on this simple question: why do so many languages and cultures identify these North American natives as “the birds from India” (oiseaux d’Inde, or simply dinde in French).

I believe one important clue is what the Turks call it themselves: Hindi (or simply, “from India). Another is the terms used by the Dutch and assorted Scandinavians, which are all variations of kalcun, indicating the specific origin of Calicut on India’s west coast.

Here, we should note many people have considered these same exact facts, and dismissed the idea there’s anything complicated to be ferreted out. Their logic goes this way: Columbus thought he’d arrived in India, and just as Native Americans were called Indians, that’s why so many Europeans referred to “the Indian bird”.

A Thanksgiving like no other: Finding uplift in a dark year

Michael Hopkins in Christian Science Monitor:

Truth is, this year has seen plenty of gratitude, instinctively and generously expressed. The people applauding out their windows for emergency responders, the heart signs, the food deliveries to essential workers, the neighborhood trash teams, the looking-in on elders. Online platforms as purpose-built as gratefulness.org and as customarily combative as Twitter have been flooded with counted blessings: for our loved ones, for the Amazon carrier, for our dogs. People gave thanks for simple things, mostly – their families, video chats, the “tall green trees that are older than me,” a hummingbird, the ocean, soup. (“Yep, soup,” says a West Sacramento, California, man.) But many, many other expressions of gratitude took the form of generosity, of trying to give back or pay it forward. The news was filled with stories of people in grocery lines paying for the customer coming next, donations to farmworkers, businesses furnishing free meals to front-line responders.

…So it has always been, this idea of hardship as a whetstone for which thanks are due. It’s easy to forget that the official Thanksgiving holiday we know today did not even exist until Abraham Lincoln created it during that hardest of national hardships, the Civil War. On Oct. 3, 1863 – just weeks before he would go to Gettysburg to give his famous address – he issued a proclamation that thanks “should be solemnly, reverently and gratefully acknowledged as with one heart and one voice by the whole American People,” and that it should be done on the last Thursday of each November. The proclamation didn’t quail from noting that the country was, indeed, “in the midst of a civil war of unequaled magnitude and severity.” And it humbly suggested that any prayers offered up might particularly “commend to His tender care all those who have become widows, orphans, mourners or sufferers.” Nevertheless, the president observed, it still was a time of peace overseas, of bounty in the fields and mines, of lawfulness in the villages.

According to Arthur Brooks, who teaches a course on happiness at Harvard Business School, “Psychologists have found that many of the most meaningful experiences in life are quite painful.”

The Art of Building the Impossible

Burkhard Bilger in The New York Times:

Mark Ellison stood on the raw plywood floor, staring up into the gutted nineteenth-century town house. Above him, joists, beams, and electrical conduits crisscrossed in the half-light like a demented spider’s web. He still wasn’t sure how to build this thing. According to the architect’s plans, this room was to be the master bath—a cocoon of curving plaster shimmering with pinprick lights. But the ceiling made no sense. One half of it was a barrel vault, like the inside of a Roman basilica; the other half was a groin vault, like the nave of a cathedral. On paper, the rounded curves of one vault flowed smoothly into the elliptical curves of the other. But getting them to do so in three dimensions was a nightmare. “I showed the drawings to the bass player in my band,” Ellison said. “He’s a physicist, so I asked him, ‘Could you do the calculus for this?’ He said, ‘No.’ ”

Straight lines are easy, curves are hard. Most houses are just collections of boxes, Ellison says. We stack them side by side or on top of one another, like toddlers playing with blocks. Add a triangular roof and it’s done. When buildings were still made by hand, the process would yield the occasional curve—igloos, mud huts, wigwams, yurts—and master builders earned their keep with arches and domes. But flat shapes are cheaper to mass-produce, and every sawmill and factory spits them out in uniform sizes: bricks, boards, drywall, tile. It’s the tyranny of the orthogonal, Ellison says.

“I can’t do the calculus on this, either,” he added, shrugging. “But I can build it.” Ellison is a carpenter—the best carpenter in New York, by some accounts, though that hardly covers it. Depending on the job, Ellison is also a welder, a sculptor, a contractor, a cabinetmaker, an inventor, and an industrial designer. He’s a carpenter the way Filippo Brunelleschi, the architect of the great dome of the Florence Cathedral, was an engineer. He’s a man who gets hired to build impossible things.

Yuval Noah Harari: When the World Seems Like One Big Conspiracy

Yuval Noah Harari in the New York Times:

Conspiracy theories come in all shapes and sizes, but perhaps the most common form is the Global Cabal theory. A recent survey of 26,000 people in 25 countries asked respondents whether they believe there is “a single group of people who secretly control events and rule the world together.”

Thirty seven percent of Americans replied that this is “definitely or probably true.” So did 45 percent of Italians, 55 percent of Spaniards and 78 percent of Nigerians.

Conspiracy theories, of course, weren’t invented by QAnon; they’ve been around for thousands of years. Some of them have even had a huge impact on history. Take Nazism, for example. We normally don’t think about Nazism as a conspiracy theory. Since it managed to take over an entire country and launch World War II, we usually consider Nazism an “ideology,” albeit an evil one.

But at its heart, Nazism was a Global Cabal theory based on this anti-Semitic lie: “A cabal of Jewish financiers secretly dominates the world and are plotting to destroy the Aryan race. They engineered the Bolshevik Revolution, run Western democracies, and control the media and the banks. Only Hitler has managed to see through all their nefarious tricks — and only he can stop them and save humanity.”

Understanding the common structure of such Global Cabal theories can explain both their attractiveness — and their inherent falsehood.

Scientists Uncover the Universal Geometry of Geology

Joshua Sokol in Quanta:

On a mild autumn day in 2016, the Hungarian mathematician Gábor Domokos arrived on the geophysicist Douglas Jerolmack’s doorstep in Philadelphia. Domokos carried with him his suitcases, a bad cold and a burning secret.

The two men walked across a gravel lot behind the house, where Jerolmack’s wife ran a taco cart. Their feet crunched over crushed limestone. Domokos pointed down.

“How many facets do each of these gravel pieces have?” he said. Then he grinned. “What if I told you that the number was always somewhere around six?” Then he asked a bigger question, one that he hoped would worm its way into his colleague’s brain. What if the world is made of cubes?
