1 . Imagine living in an apartment in Manhattan. When Covid-19 hits, you have nowhere to escape. Instead, you go up to the rooftop, where, to your surprise, other renters have come, too. After some awkwardness, everyone starts meeting nightly, drinks in hand, to share stories about themselves. This is the background setting of Fourteen Days, a “collaborative novel” edited by Margaret Atwood and Douglas Preston. In addition to these two, 34 authors of varied backgrounds contributed to the book. It is one of a growing number of new works, which are written together in some way.

AI services, such as ChatGPT, have started to become co-authors, too. Such models are also conversational machines, which can suggest phrases, give feedback and answer questions. “Cyborg authorship” is what MrRettberg of University of Bergen calls this. He published a book with Cyborg authorship, in which ChatGPT is tasked with generating reviews of famous works in the style of well-known authors — think Jane Austen writing about William Burroughs’s Naked Lunch.

Writing with collaborators, be they human or artificial, will only become more common. But individual authors will still dominate creatively. That is because collectively written books rarely make for great literature. Many contributions to Fourteen Days are cleverly woven together. But the book does not work quite well. Then there is authorial ego (自我价值感). Getting all 36 authors of Fourteen Days to agree on the text was a challenge, with some writers taking issue with how their story ended up being framed and referred to by other contributors later. And AI is not yet fully accepted in literary circles. Recently KudanRie, the winner of Japan’s top prize for literature, admitted she used ChatGPT to write around 5% of her science-fiction novel Tokyo Sympathy Tower. Such honesty is rare because most would never admit using AI. A new sort of “ghost writing” may be having a moment, but many writers will never want to name ChatGPT as their co-author.

2 . Ariel Procaccia has thought a lot about how to cut a cake over the last 15 years. As the father of three children, he knows how hard it is to divide a birthday cake to everyone’s satisfaction. But it’s also because Procaccia’s work focuses on exploring the mathematical rules for dividing stuff up fairly. One way to do that is to think abstractly about dessert.

For decades, researchers have been asking the seemingly simple question of how to cut a cake fairly. The answer reaches far beyond birthday parties. A mathematical problem at its heart, cake cutting connects strict reasoning to real-world issues of fairness, and so attracts not only mathematicians, but also social scientists, economists and more. “It’s a very elegant model in which you can distill what fairness really is, and reason about it,” Procaccia says.

The simplest approach is called the “divider-chooser” method, where one person cuts the cake into two equal pieces in his view, and the other person picks first. Each receives a piece that they feel is as valuable as the other’s. But when personal preferences are taken into account, even the easiest rule becomes complicated. Suppose Alice and Bob are to divide a cake, and Alice knows Bob prefers chocolate, she may knowingly divide the cake unequally so the smaller piece contains more chocolate. Then Bob will choose according to his preference, and Alice will get the larger piece. Both of them are satisfied with what they get, but the meaning of fairness changes in this situation.

The cake is a symbol for any divisible good. When cake-cutting principles are employed to settle disagreements, they are potentially helping the world find solutions. Procaccia has used fair division algorithms (算法) to model food distribution. Social scientist Haris Aziz is exploring situations ranging from how to divide up daily tasks to how to best schedule doctors’ shifts in hospitals.

Even after decades of investigation, cake cutting isn’t like a simple jigsaw puzzle (拼图) with a well-defined solution. Instead, over time, it has evolved into a kind of mathematical sandbox, a constructive playground that brings together abstract proofs and easy applications. The more researchers explore it, the more there is to explore.

3 . Pricing is managers’ biggest marketing headache. It’s where they feel the most pressure to perform and the least certain that they are doing a good job. All successful pricing efforts share two qualities: The policy combines well with the company’s overall marketing strategy, and the process is well-organized as a whole.

A company’s pricing policy sends a message to the market—it gives customers an important sense of a company’s philosophy. Consider Saturn Corporation (a wholly owned company of General Motors). Saturn wants to let consumers know that it is friendly and easy to do business with. Part of this concept is conveyed through initiatives such as inviting customers to the factory to see where the cars are made and sponsoring evenings at the dealership that combine a social event with training on car maintenance. But Saturn’s pricing policy sends a strong message as well. Can a friendly, trusting relationship be established with customers if a salesperson uses all the negotiating tricks in the book to try to separate them from that last $100? Of course not. Saturn has a “no hassle, no haggle” policy which removes the possibility of conflicts between dealer and potential customer. Customers have an easier time buying a car knowing that the next person in the door won’t negotiate a better deal.

Of course, there are typically many participants in the pricing process: Accounting provides cost estimates; marketing communicates the pricing strategy; sales provides specific customer input; production sets supply boundaries; and finance establishes the requirements for the entire company’s financial health. Input from diverse sources is necessary. However, problems arise when the philosophy of wide participation is carried over to the price-setting process without strong coordinating mechanisms (协调机制). For example, if the marketing department sets list prices, the salespeople negotiate discounts in the field, the legal department adjusts prices if necessary to prevent breaking the laws or contractual agreements, and the people filling orders negotiate price adjustments for delays in shipment, everybody’s best intentions usually end up bringing about less than the best results. In fact, the company may actually lose money on some orders.

4 . Those who had the pleasure of watching Benny Goodman at work saw a rather ordinary-looking man in rimless glasses and a conservative business suit; but they also saw a human being who could play the clarinet(单簧管) like no one before or since. This made Benny Goodman a unique individual.

Other Americans who have stood out from the flock include Joe DiMaggio, Beverly Sill, Ernest Hemingway and Jonas Salk. They, like Benny Goodman, were recognized and honored for no other reason than excellence.

It is doing something better than other people that makes us unique. Yet a surprising number of people still see individuality as a surface thing. They wear garish clothes, dye their hair strange colors and decorate their skin with tattoos to make some kind of social statement. But an ordinary guy who has dyed his hair purple or orange is nothing more than the same person with a funny-looking head.

The whole purpose of individuality is excellence. Those who invent, who improvise(即兴发挥), who know more about a subject than other people do, and who take something that doesn’t work and make it work––these people are the very soul of capitalism.

Charles Kettering didn’t like the idea of cranking a car to make it start, so he invented the electric starter. Henry Ford figured out the assembly-line technique and made it possible to mass-produce automobiles, and Elisha Otis, inventor of the elevator, indirectly created the city sky-line. These people understood that individualism means working at the top of one’s capacity.

The ones with the purple hair and the funky jewelry are just along for the ride, trying to be “different” and not knowing how to go about it.

The student who earns straight A’s on his report card has grasped the idea and has found the real meaning of individuality. So has the youngster who has designed his own spaceship, who gives piano recitals, who paints pictures of the world around him.

Benny Goodman understood it too. This is why he was at his best, blowing his clarinet, in a blue suit and black shoes.

5 . Obese people experience discrimination (歧视) in many parts of their lives, and the workplace is no exception. Studies have long shown that obese workers, defined as those with a body-mass index (BMI) of 30 or more, earn significantly less than their slimmer co-workers.

Yet the costs of weight discrimination may be even greater than previously thought. “The overwhelming evidence,” wrote the Institute for employment Studies, “is that it is only women living with obesity who experience the obesity wage penalty (薪资损失).” They were expressing a view that is widely aired in academic papers. To test it, The Economist has analyzed data concerning 23,000 workers from the American Time Use Survey, conducted by the Bureau of Labour Statistics. Our number-processing suggests that, in fact, being obese hurts the earnings of both women and men.

The data we analyzed cover men and women aged between 25 and 54 and in full-time employment. At a general level, it is true that men’s BMIs are unrelated to their wages. But that changes for men with university degrees. For them, obesity is associated with a wage penalty of nearly 8%, even after accounting for the separate effects of age, race, graduate education and marital status.

The conclusion — that well-educated workers in particular are penalized for their weight — holds for both sexes. Moreover, the higher your level of education, the greater the penalty. We found that obese men with a Bachelor’s degree (学士学位) earn 5% less than their thinner colleagues, while those with a Master’s degree earn 14% less. Obese women, it is true, still have it worse: for them, the equivalent figures are 12% and 19%, respectively (分别地).

Your line of work makes a difference, too. When we dealt with the numbers for individual occupations and industries, we found the greatest differences in high-skilled jobs. Obese workers in health care, for example, make 11% less than their slimmer colleagues; those in management roles make roughly 9% less, on average. In sectors such as construction and agriculture, meanwhile, obesity is actually associated with higher wages.

These results suggest that the total costs of wage discrimination borne by overweight workers in America are greater than expected. Now, it’s time for our governments to take it seriously.

7 . Suppose you come across two doctors. One is handsome while the other looks plain. Who would you trust with your surgery? Most people would probably want to get treated by the handsome one. And most people are likely to be wrong about that.

When you look at the sun, you sometimes see it clearly. But sometimes you’ll see it shining way bigger than its actual shape. That circle of light called a halo makes it look bigger. This effect, known as the halo effect, also happens when a person, product, or company shines like the sun. Then we don’t see them clearly and associate all sorts of unrelated qualities to them.

The halo effect was once studied by the psychologist Edward Thorndike, who asked flight commanders to evaluate their pilots in various distinct aspects such as physical appearance, intelligence, and leadership. He found that the pilots who got high scores for their physical appearance, also got rated high on intelligence and leadership skills — a link that seemed wrong. It appears that the commanders were unable to evaluate specific qualities independently of others. They thought of their pilots in broad terms, either “good” or “bad”, and allowed this general feeling to influence the specific qualities they credited to their pilots. Some pilots profited from their halo.

The halo effect also explains why some teachers give better-looking students higher grades. One study looked at the grades of 4,500 pupils, who were sorted by volunteers into three groups: below-average, average, and above-average looking. The researchers then compared students’ grades between classes taken in conventional classrooms with those taken online where there was no face-to-face interaction. The researchers found that students who were rated as good-looking earned significantly lower grades in online courses compared to conventional classrooms.

Since the physical appearance of good-looking people seems to naturally make them also appear intelligent, strong, and trustworthy, here is one good rule. If you meet with an accident and have to choose between two equally qualified doctors, ignore their halo and choose the less handsome one. He might have worked twice as hard to gain the same reputation and is likely better at his job.

9 . At some point in the stretch of days between the start of the pandemic’s third year and the feared launch of World War III, a new phrase unfolded itself before us, a mysterious foretell of an age to come: people were going “goblin mode”.

The term embraces the comforts of depravity(堕落): spending the day in bed scrolling endlessly through social media; pouring the end of a bag of chips in your mouth; leaving the house in your pajamas and socks only to get a single Diet Coke from the store.

First appearing on Twitter as early as 2009, “goblin mode” represents a direct departure from the “cottagecore” influence of early pandemic days, a standout trend of 2020 that thrived under the wistful ethos of making the best of what many people assumed would be only a few boring weeks at home in 2020.

But as the pandemic wears on endlessly, and the chaos of current events worsens, people feel cheated by the system and have rejected such goals. “The trend sets an unrealistic standard for people to think that if they aren’t waking up early to exercise, their lives are not put together”, one blog indicting “cottagecore” culture reads.

Most people tweeting about goblin mode characterize it as an almost spiritual-level embrace of our most debased tendencies and call it a logical progression into nihilism(虚无主义)after years of disappointment. However, Marnell, an author who has been tweeting extensively in recent weeks about entering goblin mode, says there is “healthy goblin mode and destructive goblin mode”. For her, it represents a certain air of harmless mischief. “It is cool to be a goblin,” Marnell says. “Everyone is so perfect all the time online, it is good to get in touch with the strange little creature that lives inside you.”
