John Lanchester in The New Yorker:

What are you doing? I don’t mean what are you doing with your life, or in general, but what are you doing right now? The answer, in one respect, is simple enough: you’re reading this magazine. Obviously. From a certain economic perspective, however, you’re doing something else, something you don’t realize, something with a sneaky motive that you aren’t admitting to yourself: you are signalling. You are sending signals about the kind of person you are, or want to be. What’s that you say—you’re reading this in the bath, or on your phone in bed, or otherwise in private? Well, the same argument applies. You are acquiring the tools for a “fitness display.” This, the economist Robin Hanson and the writer-programmer Kevin Simler argue in their new book, “The Elephant in the Brain: Hidden Motives in Everyday Life” (Oxford), is an advertisement of “health, energy, vigor, coordination, and overall fitness.” Fitness displays “can be used to woo mates, of course, but they also serve other purposes like attracting allies or intimidating rivals.” So there you go: that’s what you’re doing, there in the bath with the magazine. Your rivals are right to feel intimidated.

Wait, though—surely signalling doesn’t account for everything? Hanson, in a recent podcast interview with Tyler Cowen, a colleague at George Mason University, was asked to give a “short, quick and dirty” answer to the question of how much human behavior “ultimately can be traced back to some kind of signalling.” His answer: “In a rich society like ours, well over ninety per cent.” He was then asked to cite a few voluntary human activities that “have the least amount to do with signalling.” The example Hanson came up with was “scratching your butt.”

That made me laugh, and also shake my head. Economists often do. I started reading up on economics twelve years ago. I was in the early stages of writing a novel about contemporary London, and had come to the realization that frequently hits you when you are writing fiction, which is that there is a story behind the apparent story.

Lizzie Wade in Science:

The priest quickly sliced into the captive’s torso and removed his still-beating heart. That sacrifice, one among thousands performed in the sacred city of Tenochtitlan, would feed the gods and ensure the continued existence of the world.

Death, however, was just the start of the victim’s role in the sacrificial ritual, key to the spiritual world of the Mexica people in the 14th to the 16th centuries.

Priests carried the body to another ritual space, where they laid it face-up. Armed with years of practice, detailed anatomical knowledge, and obsidian blades sharper than today’s surgical steel, they made an incision in the thin space between two vertebrae in the neck, expertly decapitating the body. Using their sharp blades, the priests deftly cut away the skin and muscles of the face, reducing it to a skull. Then, they carved large holes in both sides of the skull and slipped it onto a thick wooden post that held other skulls prepared in precisely the same way. The skulls were bound for Tenochtitlan’s tzompantli, an enormous rack of skulls built in front of the Templo Mayor—a pyramid with two temples on top. One was dedicated to the war god, Huitzilopochtli, and the other to the rain god, Tlaloc.

Justin E. H. Smith at his own blog:

Some time back I took a group of students to the Galerie d’Anatomie Comparée at the Jardin des Plantes. This is the famous collection of skeletons laid out according to one version of the order of nature by Georges Cuvier at the turn of the 19th century. We were looking at a display case (added long after Cuvier’s death) that consisted in four rows, one above the other, with five skulls in each row representing five developmental stages of three species of great ape –gorillas, chimpanzees, and orangutans–, plus Homo sapiens. 

I had asked the students to pay attention to the way in which the different species, particularly the human species, seem to develop away from each other as they move from their more or less similar infant stage through adolescence to adulthood, and how the gorilla in particular develops a huge cranial crest, while the human simply develops a freakishly huge cranium (at least by comparison).

At this point a student interrupted to ask me whether each skull of the same species was from the same individual.

Pardon? I said. The student explained again that she wanted to know whether the baby gorilla skull, for example, was from the same animal as the adolescent gorilla skull and the gorilla skulls at the other three stages of development. How on earth would that be possible? I asked, still confused as to whether I had understood.

Yet, intuitively, I understood, and what she was asking was not at all strange.

Scotty Hendricks in Big Think:

In 1765, Russian Empress Catherine the Great heard that the philosopher Dennis Diderot was in dire need of money. As a well-known patron of the arts, sciences, and Enlightenment philosophers, she immediately purchased his entire library. She directed him to keep it at his home and hired him as her librarian with 25 years of salary upfront.

Diderot, whose finances had never been sound, proceeded to use some of the money to buy a very lovely scarlet robe.

This is where his troubles began. After he got used to the splendor of his new garment, he noticed that his apartment wasn’t quite as nice as it should be now that he was wearing beautiful clothes.

To fix this, he replaced his old prints with new ones. Then he noticed his armchair was no longer suitable and replaced it with a new leather one. His desk was then suddenly out of place and needed to be updated as well.

Before long, he had replaced nearly every item in his home with a shiny upgrade. In the end, he was in debt and still hungry for more material goods.

Robert B. Reich in the New York Times:

If climate change, nuclear standoffs, Russian trolls, terrorist threats and Donald Trump in the White House don’t cause you feelings of impending doom, you might think about artificial intelligence. I’m not just referring to big-brained robots taking over civilization from us smaller-brained humans, but the more imminent possibility they’ll take over our jobs.

It’s already happening. Robots and related forms of artificial intelligence are rapidly supplanting what remain of factory workers, call-center operators and clerical staff. Amazon and other online platforms are booting out retail workers. We’ll soon be saying goodbye to truck drivers, warehouse personnel and professionals who do whatever can be replicated, including pharmacists, accountants, attorneys, diagnosticians, translators and financial advisers. Machines may soon do a better job than doctors at scanning for cancer.

This doesn’t mean a future without jobs, as some doomsayers predict. But robots will almost certainly push down wages in all the remaining human-touch jobs (child care, elder care, home health care, personal coaches, sales and so on) that robots can’t do because they’re not, well, human.

Leo Mirani in 1843 Magazine:

So it is with organising my life. I have tried paper diaries, Google Calendar and to-do apps. No matter the form, what they all have in common is a rigid structure imposed from above. You have a certain number of lines for each day or a finite number of categories into which your plans must fit, or a small palette of colours to highlight or distinguish between events. It drives me insane. So I made my own system: a Google spreadsheet with columns titled “today”, “tomorrow”, “this week”, “weekend”, “this month” and “three months”, and tabs to keep track of expenses, books I’ve read, travel plans, story ideas, and general note-keeping. It’s messy and entirely manual: there are no shortcuts, no functions, no add-ons.

Which brings me to the Bullet Journal. When my colleagues at 1843 suggested I try this so-called “analogue system for the digital age”, I was sceptical. This “system” was developed by a designer in Brooklyn called Ryder Carroll, and has sparked a thriving sub-culture of “bullet journalists”. There are blogs dedicated to the art. The Instagram hashtag #bulletjournal has 2.2m pictures, many of beautiful, arty journals. The hashtag #bujo has another 1.7m. It appeared to be some sort of cult of productivity.

Becca Rothfeld in The Hedgehog Review:

Begin, for once, with the ending: the arms at an awful angle, the face blue-lipped above a blot of blood. Only later do we glimpse the woman who corresponds to the corpse. She laughs in a flashback. Or she smiles in the photograph pinned to the board where the police map the murders with thumbtacks, charting tangled speculations with lines of yarn. In light of her death, she comes to life. This is the antiordering typical of the serial killer procedural, a narrative scramble that begins with the answer and ages back toward the question. In the television series Hannibal (NBC, 2013–15), a convicted murderer impales a nurse in prison. He snaps at the officers who come to question him, “I was caught red-handed. There’s no mystery as to who done it. I did it!” Still, the officers insist that they have something to ask.

We know who did it, but the mystery of motive remains. It recurs in the spate of serial killer dramas that have proliferated in recent years, multiplying as fast as the gruesome murders we watch so raptly each week. In Mindhunter (2017–), a Netflix series set in the mid-seventies, a professor of behavioral science at the FBI Academy observes that murder has become inscrutable. In the past, people killed each other for reasons: The culprit was always the jilted lover or the cheated business partner, the cuckolded husband or the scheming heir. To solve the puzzle, we only had to track the reasons back to their sources. But beginning in the seventies, when “Son of Sam” murderer David Berkowitz shot six people “because a dog told him to,” the killer became “a black hole.” “Where do we go,” the professor asks, “when motive becomes elusive?”

Carl Zimmer in The Globe and Mail:

For four seasons, Harvard professor Henry Louis Gates has been hosting the genealogy television show Finding Your Roots. In each episode, Mr. Gates presents celebrities with a book full of research into their ancestry, drawing from genealogical records and genetic tests. On a recent show, Mr. Gates introduced the actor Ted Danson to one of his 18th-century ancestors, Oliver Smith of Connecticut. Mr. Danson learned how Mr. Smith defended his seaside town against the British during the Revolutionary War.

Mr. Danson proudly patted the page that chronicled Mr. Smith’s heroics. “Well done, well done,” he said. “I never imagined a one-of-me’s out there in the revolution.”

But when Mr. Danson turned to another page in his ancestry book, his mood swiftly shifted. Now he discovered that Oliver Smith bought a slave named Venture.

Mr. Danson fell silent. Mr. Gates tried cheering him up by pointing out that Mr. Smith later allowed Venture to purchase his own freedom.

Vasudevan Mukunth in The Wire:

It isn’t tempting to write about Elon Musk in that it is easy but in that it is an event that few thought we could witness live: a successful businessman letting his true inner recklessness show. All that Musk has done is lose composure – but sadly for him, the window he opened into his mind exposed something unsavoury and disappointing. It is tempting to write about Musk because we can for once stop speculating about how it is that Silicon Valley entrepreneurs cut from the same cloth as Musk and Peter Thiel think, and take a break from amassing piles of secondhand, implicative evidence. Now we have proof – and an opportunity to characterise the psyche of this odiously powerful class of world society.

For the uninitiated: Vern Unsworth was one of the expert divers who helped rescue the young Thai football team and its coach from the cave they had been trapped in. In an interview published over the weekend, he called Musk’s offer to help with a small submarine a “PR stunt”. Musk responded on Twitter with an ad hominem, calling Unsworth a “pedo”, short for pedophile, and following it up with “Bet ya a signed dollar it’s true”. These tweets were deleted shortly after.

From all that he has said and done over the last few months, it is evident that Musk thinks he should be celebrated more than he is and criticised less. But like a big baby, every time Musk does say such things, he is taken less and less seriously – or more by those looking for a spectacle. When someone doesn’t agree, Musk lashes out in abusive ways. His disgusting potshot at Unsworth is just the latest example and isn’t out of line with previous salvos.

David Wheatley at Literary Review:

In recent years, Flann O’Brien has often been characterised as the third member of the sacred trinity of Irish modernism, the Holy Ghost to James Joyce’s God the Father and Samuel Beckett’s God the Son. If so, he shares with the Holy Ghost a certain vagueness as to his identity: the press release that accompanies this book refers to him as ‘O’Nolan, or O’Brien, or Myles nagCopaleen or whatever his name may be’. Of these three personas, the first was a civil servant, the second a novelist and the third a satirical columnist for the Irish Times. Although they inhabited the same body, their relations were not always cordial: Flann O’Brien was effectively held hostage by his journalistic rival for two decades between the efflorescence of early novels and his re-emergence with The Hard Life (1961).

Expertly edited by Maebh Long, these letters are concerned largely with the travails of the jobbing writer. O’Brien was fascinated by St Augustine, but there are few confessions here: vitriol excepted, emotional candour is not his strong suit. Writing was a battle for O’Brien, and almost from the outset the career arc we follow is downward.

Boris Dralyuk at The Quarterly Conversation:

If a novel is especially immersive, if the voice of its narrator is sufficiently consistent and evocative, the world it describes may come to life in picturesque color. I say picturesque, rather than vivid, because a novel’s dominant colors may not be entirely lifelike; they may be closer to the rich oils of Rembrandt or the downy pastels of Degas. Such colors suggest life but also remind us of art’s mediating presence. Jacek Dehnel’s lush debut novel, Lala, for instance, is awash in the sepia tones of old photographs, a few of which punctuate the text. Like an old family album, assembled by an eccentric relative with an artistic bent, Dehnel’s work is drawn from life and enriched with intent, with a kind of aesthetic cohesion that bare facts lack.

Erica Wagner at The New Statesman:

John Edgar Wideman’s profound new book begins, as it must, with the American Civil War. The first story in this collection, “JB & FD” imagines a kind of conversation between two of the most important figures of that conflict, the white anti-slavery crusader John Brown, hanged in December 1859 for treason, murder, and inciting slave insurrection, and the black abolitionist Frederick Douglass, who had himself been born enslaved.

The story begins as historical fiction but swiftly moves away from the conventional, its ten sections shifting between the voices not only of Brown and Douglass but also that of the author himself, looking out of a motel window on a snowy morning, trying to imagine himself into his characters’ lives. He considers John Brown as a boy, driving cattle through a blizzard: “I compare his predicament to mine, and I’m ashamed.”
