1 . On March 7, 1907, the English statistician Francis Galton published a paper which illustrated what has come to be known as the “wisdom of crowds” effect. The experiment of estimation he conducted showed that in some cases, the average of a large number of independent estimates could be quite accurate.
This effect capitalizes on the fact that when people make errors, those errors aren’t always the same. Some people will tend to overestimate, and some to underestimate. When enough of these errors are averaged together, they cancel each other out, resulting in a more accurate estimate. If people are similar and tend to make the same errors, then their errors won’t cancel each other out. In more technical terms, the wisdom of crowds requires that people’s estimates be independent. If for whatever reasons, people’s errors become correlated or dependent, the accuracy of the estimate will go down.
But a new study led by Joaquin Navajas offered an interesting twist (转折) on this classic phenomenon. The key finding of the study was that when crowds were further divided into smaller groups that were allowed to have a discussion, the averages from these groups were more accurate than those from an equal number of independent individuals. For instance, the average obtained from the estimates of four discussion groups of five was significantly more accurate than the average obtained from 20 independent individuals.
In a follow-up study with 100 university students, the researchers tried to get a better sense of what the group members actually did in their discussion. Did they tend to go with those most confident about their estimates? Did they follow those least willing to change their minds? This happened some of the time, but it wasn’t the dominant response. Most frequently, the groups reported that they “shared arguments and reasoned together”. Somehow, these arguments and reasoning resulted in a global reduction in error. Although the studies led by Navajas have limitations and many questions remain, the potential implications for group discussion and decision-making are enormous.

I was invited to a cookout on an old friend’s farm in western Washington. I parked my car outside the farm and walked past a milking house which had apparently not been used in many years. A noise at a window caught my attention, so I entered it. It was a hummingbird (蜂鸟), desperately trying to escape. She was covered in spider-webs (蛛网) and was barely able to move her wings. She ceased her struggle the instant I picked her up.
With the bird in my cupped hand, I looked around to see how she had gotten in. The broken window glass was the likely answer. I stuffed a piece of cloth into the hole and took her outside, closing the door securely behind me.
When I opened my hand, the bird did not fly away; she sat looking at me with her bright eyes. I removed the sticky spider-webs that covered her head and wings. Still, she made no attempt to fly. Perhaps she had been struggling against the window too long and was too tired? Or too thirsty?
As I carried her up the blackberry-lined path toward my car where I kept a water bottle, she began to move. I stopped, and she soon took wing but did not immediately fly away.
Hovering (悬停), she approached within six inches of my face. For a very long moment, this tiny creature looked into my eyes, turning her head from side to side. Then she flew quickly out of sight.
During the cookout, I told my hosts about the hummingbird incident. They promised to fix the window. As I was departing, my friends walked me to my car. I was standing by the car when a hummingbird flew to the center of our group and began hovering. She turned from person to person until she came to me. She again looked directly into my eyes, then let out a squeaking call and was gone. For a moment, all were speechless. Then someone said, “She must have come to say goodbye.”

Self-esteem is the ruling view you have of yourself. This includes your beliefs about your inner qualities and how you think others see you.
People with healthy self-esteem don't need to boast about themselves to others. People with low self-esteem may tell you how much everyone loves them, what a great job they do at work, and how amazing they are at pretty everything under the sun even though they really wonder if it's true. People may see them as obnoxious or “full of themselves”.
If you're starting to think you may have low self-esteem, you can work on the way you talk to yourself. When you turn off negative self-talk, you can open the floor to positive reinforcements and access the courage to show different sides of yourself. It isn't going to feel good at first, though. Keep going until it becomes less and less and maybe even a few awkward laughs in the mirror may help.
However, in serious cases of low or even non-existent self-esteem, you may want to call in a professional or a specialist. Good mental health is important, and professionals doing psychotherapy do not pass judgement or give corrections.
A.Self-esteem is not always rooted in reality, though. |
B.You have the power to shape a new self-perception. |
C.This encourages you to speak openly without worry. |
D.The real test of character is whether they can learn from their mistakes. |
E.Self-esteem refers to a person's overall sense of his or her value or worth. |
F.People with a healthy level of self-esteem present themselves with a casual confidence. |
G.With some practice and persistence, you will win this internal struggle to see your self-worth. |
4 . A huge crowd has gathered to watch China’s new scientific research ship enter the water for the first time. This ship, equipped with on-board labs and the latest scientific kit, will eventually explore the world’s oceans. But it is also going to help China plunge beneath the waves: it will serve as a launch-pad for submarines that can dive to the deepest parts of the ocean. “Humans know much less about the deep oceans than we know about the surface of the Moon and Mars. That’s why I want to develop the facility for ocean scientists to reach the deep seas,” says Prof. Cui Weicheng.
He is the dean of deep sea science at Shanghai Ocean University but he has also set up a private company called Rainbow Fish, which built the new research ship and is busy developing submersibles. One of its unmanned subs reached a depth of 4,000m (13,000ft) in its most recent trial. But Rainbow Fish’s ultimate goal is manned exploration and it plans to take humans to the very bottom of the ocean the Mariana Trench, in the Pacific, at a depth of nearly 11,000m (36,000ft). He shows me around a life-size model of the submarine and explains that there is room inside for a crew of three, who will be protected by a thick metal sphere.”At the moment, we are in the design stage, so we are testing several extremely high-strength materials for it.” It will have to bear immense pressures from the crushing weight of water above. If there are any weaknesses, the submarine will implode. The deepest ocean is a place few people have ever experienced first-hand. The first dive to the Mariana Trench was carried out in 1960 by US Navy Lieutenant Don Walsh and Swiss engineer Jacques Picard. Their vessel, the Bathyscaphe Trieste, creaked and groaned as it made the descent, taking nearly five hours.
The only other manned expedition was carried out by Hollywood director James Cameron, who took a solo plunge in a bright green submarine in 2012. Rainbow Fish wants its sub to be next. The team insists its venture isn’t about politics and that it is looking to collaborate with American, Russian and European scientists. It is, though, a commercial operation. The company plans to charge people to use its research ship and submarines, and is targeting three groups, says managing director Dr. Wu Xin. “The first is definitely the scientists who are interested in studying deep-sea science and technology. The second group is offshore companies and oil companies. The last one is tourists and adventurers [who] want to go down themselves to have a look at what’s going on there,” he says. This kind of entrepreneurial approach may be a new model for science in China. Deep-sea research is a difficult, high-risk activity — and much of the ocean remains unexplored. But Cui, who hopes to be the first Chinese person to reach the Mariana Trench, believes that China could be the nation to truly open up this final frontier.

6 . Last week, I sent the same request to ChatGPT, the latest artificial-intelligence chatbot from OpenAI. “Upon the Firth of Forth, a bridge doth stand,” it began. In less than a minute, the program had created in full a rhyming Shakespearean sonnet (莎士比亚十四行诗). Tools like ChatGPT seem poised to change the world of poetry — and so much else — but poets also have a lot to teach us about artificial intelligence. If algorithms (算法) are getting good at writing poetry, it’s partially because poetry was always an algorithmic business.
Even the most rebellious (叛逆的) poets follow more rules than they might like to admit. When schoolchildren are taught to imitate the structure of sonnet, they are effectively learning to follow algorithmic constraints. Should it surprise us that computers can do so, too?
But considering how ChatGPT works, its ability to follow the rules for sonnets seems a little more impressive. No one taught it these rules. It is based on a newer kind of AI known as a large language model (LLM). To put it simply, LLMs analyze large amounts of human writing and learn to predict what the next word in a string of text should be, based on context. One frequent criticism of LLMs is that they do not understand what they write; they just do a great job of guessing the next word.
When a private verse by Dickinson makes us feel like the poet speaks directly to us, we are experiencing the effects of a technology called language. Poems are made of paper and ink — or, these days, electricity and light. There is no one “inside” a Dickinson poem any more than one by ChatGPT. Of course, every Dickinson poem reflects her intention to create meaning. When ChatGPT puts words together, it does not intend anything. Some argue that writings by LLMs therefore have no meaning, only the appearance of it. If I see a cloud in the sky that looks like a giraffe, I recognize it as an accidental similarity. In the same way, this argument goes, we should regard the writings of ChatGPT as merely imitating real language, meaningless and random as cloud shapes.
When I showed my friends the sonnet by ChatGPT, they called it “soulless and barren.” Despite following all the rules for sonnets, the poem is predictable. But is the average sonnet by a human any better? If we now expect computers to write not just poems but good poems, then we have set a much higher bar.

8 . “I’m not a reader.” It’s a common reply that Julia Torres, a teacher-librarian in Denver Public School, has heard throughout her 16-year career. She’s seen students tear up books, throw them away or check them out only to immediately return them all because they didn’t have confidence in their ability to read.
As a librarian, Torres feels strongly that libraries should be spaces of liberation, places where students can develop a love of reading at any stage. Reading is a skill that everyone can grow to love, but too many negative experiences during a child’s literacy (读写能力) education can result in boredom, lack of interest or even anger. When a student has a poor experience like being shamed for their reading choices, they can begin to associate reading with painful feelings of insecurity, shame and stress.
To prevent reading disorder (阅读障碍) practices, as Torres notes, librarians first can build an inclusive (内容丰富的) library where classified collections can make it easier for students to find out the books they want and also help identify gaps in the collections. Reevaluating librarians’ role is necessary, which allows students to take control of the library and have a say in what’s purchased for the collection, directly exciting students’ reading interest. Instead of hosting traditional book fairs where students have to pay for books, it is better to open up a True Book Fair, where students are invited to choose books intentionally to their interests without any costs. Librarians are recommended to read what students are reading. Another two important approaches to preventing reading disorder are to take a look at the library policies and redefine (重新定义) what counts as reading. It is necessary to get rid of fines, check-out limits, security gates, and punishment policies. Plus, students are encouraged to listen to audiobooks or read picture books. Find a way to teach important skills like comprehension or critical thinking with the texts that excite and interest students.

9 . Group-Centered Societies Have Just as Much Creativity

In the new creativity study, researchers investigated innovation with these two groups in mind. The team used a drawing test that had been created by psychologists. They gave kids a sheet of paper with just a few basic elements printed on it: some dots here, squiggles (弯曲的线条) there, and a rectangle that suggested a drawing frame. The children got 15 minutes to use the elements already on the page to draw whatever they wanted. They could get “adaptive creativity” points for doodling in ways that connected the squiggles and lines into an original and
The researchers gave the test to 683 middle school students from north and south of the Yangtze River.
