1 . Imagine you need milk, so you go to the grocery store to pick some up, only to find there are dozens of options. These days, you have to make a decision on not only the percentage of fat you want, but also what source you want your milk to be coming from: cows, soybeans... You have no idea what milk to pick. There are so many choices that you are confused.

This phenomenon is known as the paradox (悖论) of choice and it is becoming a concern in the modern world, where more and more options are becoming easily available to us. While we might believe that being presented with multiple options actually makes it easier to choose one that we are happy with, and thus increases consumer satisfaction, having too many options actually requires more effort to make a decision and can leave us feeling unsatisfied with our choice.

The idea was popularized by American psychologist Barry Schwartz when he published his book, The Paradox of Choice: Why More Is Less. Schwartz, who has long studied the ways in which economics and psychology intersect (交叉), became interested in seeing the way that choices were affecting the happiness of citizens in Western societies. He identified that the range of choices that we have available to us these days is far greater than that people had in the past; however, consumer satisfaction has not increased as much as traditional economics theories might expect.

Schwartz identified that the paradox of choice carries the most consequence for people that are maximizers. Maximizers, unlike satisficers, are concerned with making the best choice instead of simply making a choice that they are happy with. When there are many options available to maximizers, it becomes harder for them to determine which is the best, which can cause them to feel a great deal of regret after they have made a choice.

Instead of believing that freedom of choice is unlimited, Schwartz advocates that the role of psychology and behavioral economics should be to find the kind of limitations on freedom that can lead to the greatest level of happiness within society.

2 . Younger generations of Chinese citizens have developed new methods to relieve stress, which include raising unconventional “pets”, hugging trees, watching stress relief videos and so on.

On social media platforms, a new toy called “mango dog” recently emerged.     1     In the eyes of some netizens, the “mango dog” has special meanings. “Every time I see it, it heals me,” “It’s fluffy (毛茸茸的) and cute.”     2     For example, college students have shared online their experiences of raising stones and paper box “dogs”. These “pets” share similar characteristics—they don’t cry, make noise or get sick.

Tree hugging has also become a new stress relief for young people. “You may think you are hugging the tree, but in fact, the tree is embracing you,” this is a feeling shared by a netizen. Many netizens with such experiences have expressed that their anxiety has been reduced, and they feel a sense of communication with nature.     3    

“I came across the idea online. I tried it and felt truly relaxed,” said a young office worker. “In those brief seconds, it felt like the tree released a lot of pressure and stress from me.”     4     “I especially enjoy watching stress relief videos, like washing blankets and cutting soap. After watching them, I feel like the stress of the day is relieved and it’s easier to fall asleep.”

    5     According to public data, there are currently more than 800 companies in China with names, business scopes, products, services or trademarks containing the term “stress relief”. In 2023 alone, more than 70 new registered companies with this focus were added.

3 . The European Towns and Cities That Are Magical at Christmas

The town of Hallstatt and its beautiful landscape enjoy UNESCO protection. The old townhouses, tiny lanes and snow make this the ultimate destination forgetting into the festive mood. Hallstatt’s Christmas market is the stuff of legend. Picture a brightly lit tree and stalls selling decorations and handicrafts and you’re halfway to imagining just how special this spot is.

Valkenburg has much of the usual European Christmas charms to attract visitors. However, what makes it special is the fact that they can all be found underground. The town’s Christmas Caves have become internationally renowned, with a wide range of stalls selling festive gifts and decorations. The larger Municipality Cave is home to one of the largest indoor Christmas markets in Europe.

Wroclaw is regarded as one of Poland’s most beautiful cities, but it takes things to another level at Christmas. The city’s Christmas market is home to over 250 stalls and a superb fair. The architecture here captures the Christmas feeling too, with Gothic structures meaning everyone can tap into the special feeling that only comes round at this time of year.

Gothenburg is full of festive surprises for those willing to risk traveling north and brave the Scandinavian chill. And chief among them is the Liseberg Christmas Market. Set in an amusement park celebrating its100th anniversary in 2023, visitors can enjoy rides here and taste delicacies (佳肴) from across the country, including pickled herring, reindeer and spiced wine.

When something that’s important to you disappears, don’t be hopeless. It may miraculously (奇迹般地) come back sooner or later. I learned it on one winter day.

It was one of those busy days. Especially, I had lots of clothes to wash. and Karen, my four-year-old kid, kept following me, pulling my shirt and crying for attention. I was annoyed. To stop her troubling me and make her quiet, I searched the drawers in the bedroom and found-a bag of forgotten balloons. “Yellow,” she said with joy.

The balloons were the gifts for her that her uncle had bought abroad. These balloons were of good quality and very unique, unable to be found at least in our small town. Among the balloons, the yellow one was Karen’s favorite. And there was only one yellow balloon. She viewed it as her best friend and even signed her name on its surface.

After I blew the balloon up, she cheerfully took it with tiny fingers, touching it and telling it her secrets. Immediately. her attention was attracted.

After lunch. we prepared to go to the local public clothes-washing shop. Before long. I was ready. Carrying her yellow balloon. Karen followed me into oat car. On the way, she was singing and had fun with the balloon. She kept beating the balloon against the back of the car seat. As I turned the corner, trying to keep my attention on my driving, I felt a sudden, big wind blow across my feet. I called out at once, “Karen! Close the window. It’s cold out!”

And then I heard her frightened scream. In a hurry, I looked over my shoulder, expecting to see some terrible insects that led to her being frightened. But there wasn’t one. Karen was looking out of the window. both arms reaching out, as if to get something. And she cried, “Balloon, balloon. Come back! Come back!” Then. she turned to me, calling out, “Mom, please stop the car! My balloon has escaped.”

“Alright, “I said and slowly pulled over.

While walking in the park, we suddenly found a yellow balloon flying over a tree.

5 . Christian Bowers, now 24, has Down Syndrome (唐氏综合征) and it’s been hard for him to find good friends. His mom, Donna Herter, said his lack of friends was making him feel ________.

Herter didn’t know who to turn to. So, she posted it on Facebook. “I just basically said that I was looking for a young ________,” she said. “I told them that I’d pay them $80 for two hours to just ________ and play video games with him. All he ________ wants is just a guy friend to do guy stuff with.”

Herter said Christian attends events for people with special ________, but he “desires a friendship with somebody who is ________”.

Herter sent the post at I am and when she woke up, it had about 5,000 comments. She saw parents ________ suggestions, others volunteering to help. “My hands were ________. I was sweating,” she said.

After ________ a few local guys in Wentzville, Minnesota, Donna ________ it down to seven who now visit Christian once a week.

James Hasting was one of the men she ________. Hasting said he works with people with disabilities and it’s something he has a(n) ________ for. He said he had visited Christian three times so far and they had a wonderful time together.

“Though on the ________ we may look different, deep down we have ________ and getting along should be easy,” Hasting said. He hopes to ________ others to form friendships-because you never know how much it means to someone.

6 . Think of your most prized possession. Now, imagine you decide you must sell this item. How much is it worth to you? How much would you charge for it? And would anyone else want to buy it at that price?

Let’s consider the real-world example of a yard sale. Before your neighbors come to look at your things, you must first decide on the prices for them. For you, each item has a story, and some items may even evoke strong emotions.

Let’s say you’re selling a pair of special edition sports shoes that you took care of and really enjoyed wearing on special occasions. With these sweet memories in mind, you put a price tag of $130 on the shoes. However, a customer offers $50 for them. You think, “How could they not see how special and valuable these are?”

In financial transactions like this, sellers often believe their own items are worth more than what buyers are willing to pay. This occurs because buyers do not have the seller’s experiences with and emotional attachment to the items. Buyers want a good deal, and they’re not willing to pay what the seller is asking for.

This negotiation process can even feel a little painful for the seller—over losing something and the buyer not valuing it as much. Economists suggest this dynamic occurs through the endowment effect (禀赋效应)—people’s tendency to value things they own more highly than they would if they did not own them. The endowment effect can take hold anytime we feel a sense of ownership over a product, and it can happen quickly.

As the saying goes, “Emotions get the best of us.” There is nothing wrong with being proud of owning things and treasuring your experiences with them. But when you consider selling a prized possession, think about whether you’re fully ready to part with it. The past is the past, though. Removing your emotional attachment to material possessions can help you make more accurate assessments of how much your items are truly worth.

9 . Why does the giant squid (乌贼) have eyes as large as a football? Why do more than 350 species of fish produce their own electricity? Why do dogs become more optimistic after two weeks of plentiful sniffing (嗅)?

The mysteries and miracles of animal senses are revealed in this year's winner of Royal Society Trivedi science book prize. An Immense World by Ed Yong is an exploration of the unique sensory world of other creatures, from tree hoppers to singing frogs, who sense the world in vastly different ways to humans.

Yong has interviewed many kinds of scientists during his writing but sensory biologists are his favourite. “There's a surprising number of sensory biologists who are themselves neuro-atypical—they have something like face blindness or colour blindness,” he says. “Their different than‘normal’ way of experiencing the world themselves might help them better empathize (共情) with other creatures who have those experiences. The core of this book is curiosity and empathy, understanding and valuing animals for their own benefit, and trying to put ourselves in the shoes of creatures who are very different to us.”

Yong's book carries an important message about how our lack of understanding of the sensory worlds of other animals is hugely destructive. Studies have shown that LED lights are particularly damaging to bats and insects. Flowers illuminated (照亮) by bright lights receive 62%fewer visits from insects. Meanwhile, low-frequency noise in oceans has risen 32-fold since the Second World War because of global shipping-damaging whales' ability to communicate.

Unfortunately, reducing noise and light pollution is nowhere near the political agenda. "It's understandable why it's not on the political agenda because it's not a visceral (强烈的) problem like a plastic-ridden beach or chemicals billowing from a smokestack, ”says Yong. “Light and sound don't produce the same kind of horror. Light especially feels like an entirely good thing-we want more light in our lives; light is knowledge, safety, beauty and goodness. So just raising awareness that these are problems that could be tackled is an important first step and one I hope An Immense World moves people further towards taking."

10 . African grey parrots (鹦鹉) help their peers complete tasks despite no immediate benefit to themselves, researchers have found in the first study to show that birds display such apparently “selfless” behaviour.

Writing in the journal Current Biology, Brucks and colleagues report how they tested African grey parrots in a task that involved the birds passing a token, in the form of a metal ring, through a hole in their section to a neighbouring bird of the same species. This token could then be passed by the second bird to a human, via another hole, who would exchange it for a piece of nut.

The team found African grey parrots helped their neighbours by passing tokens to their neighbour when a human held out their hand, allowing the second bird to drop it through-the hole and receive a tasty treat.

The same behaviour was seen when the roles of the birds were reversed (颠倒). The more tokens a bird had previously given, the more they received in return.

However, the team stress previously the birds did not know that their favour would be rewarded, suggesting it is something of a “selfless” act.

The team say it may be due to African grey parrots gathering in huge flocks at night but splitting into smaller groups during the day to forage (觅食). Brucks said such behaviour is thought to require strong social cognitive (认知) abilities, adding that being helpful might help the birds gain a good reputation with their peers, making it more likely they would team up for foraging and other tasks.

Dr Manon Schweinfurth, an expert in animal behaviour, said evidence of reciprocal (互惠的) behaviour in African grey parrots is quite interesting. “It has been thought that it is so cognitively demanding that only humans can show it. But we now get more and more evidence from other animals that they are able to show reciprocity,” she said.
