5 . Pullman is a superb writer and Seagull is a brilliant communicator. They had a debate after Seagull posted a question on his social media platform: “When you were trying to create an environment for learning, what were your best pieces of classical music to listen to?” He received hundreds of suggestions — and one negative reply, from Pullman: “That’s not what classical music is for. Treat it with respect.”

That did it! Everyone — professional musicians, students, teachers — weighed into the argument, and the majority supported Seagull and were criticizing Pullman.

It’s easy to see why people are annoyed. We all want classical music to be as accessible as possible, especially to the young. If some of them are using Bach or Schubert as a tool to help them study, what’s the problem? They may also develop an attachment to classical music.

So is Pullman ridiculous and supercilious by objecting to classical music being used as background music? At first sight, his idea seems stuffy and extreme. By suggesting that classical music should be “treated with respect” and not used as background music, Pullman seems to be closing classical music of to millions of people.

It’s worth pointing out, however, that he isn’t the first to express concerns about classical music being devalued by becoming too commonplace in today’s technologically shaped world. In Benjamin Britten’s 1964 speech, the composer expressed exactly the same worries as Pullman. Britten suggested, “The true musical experience demands some preparation, some effort, a journey to a special place, saving up for a ticket, some homework perhaps”. In short, it demands as much effort from listeners as from composers and performers.

I don’t agree with such an extreme viewpoint, but I do think it touches on a reality. You will never fully grasp the beauty of classical music if you half-hear it only in the background. That doesn’t necessarily matter. Music can be enjoyed on many levels. What Pullman and Britten are really saying is that, in a drive for “accessibility”, we shouldn’t deny the emotional and intellectual complexity underpinning (构成) much classical music.

6 . The pandemic has affected nearly all aspects of modern life, from the clothes we wear to the food we eat. There is one thing, however, that has remained almost unchanged: the emojis we send.

According to data from the Unicode Consortium (统一码联盟), nine of the 10 most-used emojis from 2019 also ranked among the top 10 this year. The tears of joy emoji ranked No.1, despite members of Gen Z deeming it uncool.

“It speaks to how many people use emojis. If emojis were a purely Gen Z thing, then you wouldn’t see it so highly ranked,” said Alexander Robertson, an emoji researcher at Google. “Because of the large number of people using emojis, even if one group thinks something is lame, they have to be a really big group to affect these statistics.”

And it makes sense that Gen Z would think that certain emojis aren’t fashionable. It’s part of the “teenager experience of creating a sense of subculture where there’s a right way and a wrong way of behaving.” Plus, there is a range of laughter that can be expressed: There’s light chuckling. There’s acknowledgement laughter, which is just a marker of empathy. Using emojis, such as the skull face (“I’m dead”) or crying face ( uncontrollable tears of laughter), can help to illustrate that range.

“It basically indicates that we have what we need to communicate a broad range of expression, or even very specific concepts,” Mr Robertson said. “You don’t necessarily need a Covid emoji.”

“We did see a rise in the use of the virus emoji. But it wasn’t made remotely into the most-commonly used ones because we still had plenty to laugh about and plenty to cry about, whether it was because of the pandemic or not,” said Lauren Gawne, a senior lecturer in linguistic at La Trobe University in Melbourne, Australia.

“Even in the midst of this massive global pandemic that preoccupied so much of our time,” She added. “We still spent a lot of time wishing each other happy birthday or checking or laughing about some new and unexpected elements of this slow-burning weirdness.”

7 . This question has fascinated behavioural scientists for decades: why do we give money to charity?

The explanations for charitable giving fall into three broad categories, from the purely altruisic (利他的)— I donate because I value the social good done by the charity. The “impurely” altruistic— I donate because I extract value from knowing I contribute to the social good for the charity. And the not-at-all altruistic— I donate because I want to show off to potential mates how rich I am.

But are these motives strong enough to enable people to donate as much as they would want to? Most people support charities in one way or another, but often we struggle to make donations as often as we think we should. Although many people would like to leave a gift to charity in their will, they forget about it when the time comes.

Many people are also aware that they should donate to the causes that have the highest impact, but facts and figures are less attractive than narratives. In a series of experiments, it was found that people are much more responsive to charitable pleas that feature a single, identifiable beneficiary(受益者), than they are to statistical information about the scale of the problem being faced. When it comes to charitable giving, we are often ruled by our hearts and not our heads.

The good news is that charitable giving is contagious—seeing others give makes an individual more likely to give and gentle encouragement from an important person in your life can also make a big difference to your donation decisions— more than quadrupling them in our recent study. Habit also plays a part— in three recent experiments those who volunteered before were more likely to do donate their time than those who had not volunteered before.

In summary, behavioural science identifies a range of factors that influence our donations, and can help us to keep giving in the longer term. This is great news not just for charities, but also for donors.

10 . What goes on in our brains when we decide to hit the share button, and what makes something go viral? Since the dawn of the Internet, businesses, media outlets and influencers alike have been trying to answer these questions. Now, researchers have come one step closer to cracking this mysterious model by shining a light on the neuroscience (神经科学) of viral content.

“Our study finds a way to obtain brain signals that would predict how much information gets shared.” said Emily Falk, professor of communication, psychology and marketing and Hang-Yee Chan, a lecturer of communication.

Their new study, published in Proceedings of the National Academy of Sciences on October 23, investigated both the U. S. and the Netherlands using a broader range of news categories—including health and climate change.

“When we see greater activation of regions that track self-relevance (Is it important to me) and social-relevance (Is it important to people I know), the news articles are more likely to be shared widely,” Falk and Chan said. By studying these brain responses, the team managed to build a value-based model to accurately predict how widely the articles would be shared online. This link between brain activity and sharing was seen in both the American and Dutch participants, suggesting that this model is accurate across cultures.

“Seeing how people’s brains react inside the scanner gives us insight into why people ultimately share information nowadays,” Chan said. “If we understand these signals, we might be able to use that knowledge to help important news get shared and stop misinformation from going viral.” It is also helpful for content creators to maximize their reach. “Our current study demonstrates how tapping into the brain would help content creators optimize their messages’ influence,” Falk and Chan said. “We are interested in building on these results to develop ways to counter harmful information and false news, in addition to spreading high-quality content.” “A lot of our most pressing problems in society are influenced by the decisions people make, and the decisions we make are influenced by the news. What you share matters, and so understanding why you share it matters, too.”
