How do you get your information when you go online? Are you ever worried that you might only be seeing a limited view? Part of the reason for this is the increased use of Artificial Intelligence (AI) and algorithms that make sure we only see things that interest us.
The phrase “echo chamber” has become widely used since events like the election of Donald Trump as the US president. It means that users of social media websites such as Facebook only read their own opinions or ones they agree with.
Algorithms, like the kind used by Facebook, often point us toward articles that show our own ideas, and search results usually give us what we already know and like.
As a result, social network users are likely to fall into the “Relevance Paradox”, which happens when people only read information that is relevant to them, according to The Huffington Post. And in many cases, people don’t even realize this is happening. They stop looking for fresh, new information from different points of view because of a lack of experience and knowledge of other opinions.
This means some of us unknowingly live in an echo chamber. This then continues because people in the same social group agree with us too. In other words, the echo chambers stay because they tell us that we are right, even if we are not.
As websites get to know us better, they get better at showing us things that interest us, while also removing things we don’t really like, Eli Pariser, CEO of news website Upworthy told the US radio station NPR.
“What most algorithms are trying to do is to increase the amount of attention you’re spending,” he said. And while it helps us deal with the large amount of information on the internet, that algorithm also has some downsides. “The danger is that you end up not seeing what people who think differently see and, in fact, not even knowing that it exists.
So here comes the burning question — is there a way out?
“The way to break free from this is to start understanding how algorithms work, and to manually seek out others with different viewpoints,” Theo Priestley, CEO of Cronycle, a web platform told The Huffington Post.

【推荐1】New Yorker writer Kyle Chayka came of age alongside the internet. As a teen, he published his own blog and joined forum (论坛) for pop music. He discovered one of his favorite Jazz songs --- John Coltrane’s full version of “My Favorite Things” – driving around at night, listening to the local radio station.
Chayka misses the time ---and the ways, then, that personal discoveries like these were made. In his new book, Filterworld: How Algorithms (算法) Shaped Culture, Chayka says he never would have fallen in love with Coltrane’s songs if he’d heard it on Spodify. He says he doubts Spodify’s algorithm would even suggest it, because the song is so long. And that, even if it did, he wouldn’t have learned anything about Coltrane as an artist, because the Spodify interface doesn’t provide the same context that a radio DJ does, sharing details between songs. The person behind the song choice, he argues, made his emerging interest in Coltrane possible in a way modern recommendation system cannot.
This is one of many “back in my day” stories Chayka uses to illustrate his argument that algorithms have “shaped culture”. Thanks to recommendation generators like Tiktok’s top picks and Spodify’s autoplay suggestions, “the least troublesome and perhaps least meaningful pieces of culture are promoted,” Chayka argued. He admits that quality is subjective when judging these things, and instead argues that recommendation systems undermine personal taste. Taste, he writes, was once a combination of personal choices and popular influence --- but now algorithms rely more on choices of the masses. Developing taste requires effort and active engagement, but what we see now are algorithms turning taste into consumerism.
A central point of the book, in fact, is that people today are not only well aware of the power of algorithms, they can’t escape them. He interviews a young woman who wonders if “what I like is what I actually like,” worried that her taste is so shaped by algorithms that she can’t trust herself. The book may be most useful in these sections, where Chayka and his interviewees attempt to make sense of how internet algorithms have shaped their own lives and work.

【推荐2】A middle-aged woman playing by herself in the snow is an undeniably odd sight, but maybe it shouldn’t be. New research suggests that modern adults are suffering from overmuch depression, so play may be as essential to our health as sleep. We’ve been in our nature to play, which is causing all kinds of problems—for ourselves, our children, and our planet.
It’s believed that adult play can lead to useful discoveries, which is supported by a study on Bali’s long-tailed monkeys. For her doctoral paper at the University of Lethbridge, animal researcher Camilla Cenni left two types of puzzle boxes for the monkeys to solve. To get the food inside, they had to drop a rock into the container or use it to hit the box. She found the monkeys that previously had been observed dropping rocks for fun were more likely to solve the rock-dropping puzzle, while those that had discovered the joy of tapping rocks together think of the answer to the tapping puzzle.
This finding also suggests that somewhere, deep in our evolutionary history, a playful proto-human(原始人) came up with the concept of stone tools. Even today, the urge to play underlies most of humanity’s greatest inventions, artworks, and scientific breakthroughs, Brown says. “When I interviewed Nobel winners, I was struck by how most of them didn’t separate work and play. Their labs were their playgrounds”.
“The opposite of play isn’t work; it’s depression,” says play researcher Stuart Brown, “Play is all about looking at a tough world with creativity and optimism. It gives us the ability to cooperate and get along with people who differ from us,” He goes so far as to declare that “adult play is necessary for our survival as a species.”
The next time I’m caught playing, I know exactly what I’ll say: “I am not wasting time, or acting immature. I’m doing nothing for the benefit of all humanity. You’re welcome.”

【推荐3】“PLEASE DON’T KILL HIM” said Mrs. Reid with tears in her eyes. “I’m really sorry,” I said, hardly able to look at her. A nurse held her hand and tried to comfort her.
“He’s been my entire world for 14 years, I don’t know what I’ll do without him,” she said with tears in her eyes. She wasn’t talking about a person. She was talking about Toby, her King Charles spaniel. Mrs. Reid had come into hospital after she’d fallen. She had Parkinson’s disease, meaning her ability to move was worsening. It was the second time she’d fallen in just a few weeks, and this time she’d broken her hip. While the hip had now been fixed, it was clear that she was too frail (脆弱的) to go home, and the social workers had arranged for her to go into a care home. A neighbor had been looking after Toby, but with Mrs. Reid no longer going home and as she had no family who could take him, it looked likely that he’d have to be killed. She was begging me to allow her home, but it was simply too dangerous.
This situation is far from unique. Research has found that each year thousands of dogs are put down because their owners go into care homes. Over 100,000 have to be rehomed. Thankfully I spoke to a kindly social worker who eventually found a care home for Mrs. Reid that would allow her to take Toby with her. But these places are few. I think we need to seriously re-examine what’s happening here. It seems completely wrong. There is no doubt that we are a nation of animal lovers. Many of us consider our pets to be part of the family and there’s a fair few of us, I guess, that actually prefer our pets to a good number of people. Humans have a great ability to draw comfort and support from animals. For older people like Mrs. Reid, they are often the important source of companionship (陪伴) and about a quarter of old people have a pet. Yet when they come into hospital or a care home, they are denied this relationship.
While the US, France, Norway and Switzerland all have laws forcing housing providers to accept pets belonging to elderly people, studies have shown that around 70 per cent of care homes in the UK forbid elderly people from bringing pets. This figure has risen in recent years and is likely to be due to increasing concerns around “health and safety”. However, research has concluded that they are “necessary to elderly people’s quality of life” and that having to move to care homes without their pets was psychologically similar to losing their family. It seems outrageous (可耻的) that care homes—whose purpose is to ensure the elderly people’s welfare (福利)—are able to deny them something which has proven clinical benefits for their health.

【推荐1】With nearly a quarter of global greenhouse gas coming from all types of transportation, can we keep ourselves off gas-powered vehicles to avoid the worst effects? As more governments push for urgent action on climate change, quite a few companies are betting their future – that millions of consumers are finally ready for electricity-powered vehicles. Modern battery-powered cars are selling fast and zero- emission ( 排放) planes are coming. These changes, both leading to a more sustainable future, are reinventing how we get from here to there.
Cars and trucks are undergoing their greatest improvement since the automobile’s (汽车) existence more than a century ago. Almost overnight, the era of the electric car has arrived. Electricity has the advantage that it works without smell and with less noise. Global annual sales of electric vehicles are expected to soar from just over 3 million today to 14 million by 2025. Just a month after Ford unveiled an electric version of the popular F-150, customers had reserved more than 100,000 of them. The price is about $10,000 above the gas-powered one, but Ford says the electric model will cost much less to maintain. Everything creating a green revolution on the ground is of limited help in the sky for the time being.
High-storage batteries are useless at present when it comes to the technological challenge of launching a few hundred people into the sky and carrying them thousands of miles. No battery yet invented can power, say, a Boeing 747 from New York to London. Promising improvements, however, do add up. Developments with zero-emission, battery-powered electric engines are already happening in commercial flight, involving trips of limited duration and distance. Airlines specializing in short journeys with small planes will lead the way to electric flight.
Our planet’s health depends on zeroing out carbon dioxide emissions by 2050, and yet, by the timetable needed to address the climate challenge, the shift away from gas-powered vehicles remains far too slow. Nevertheless, the train has left the station. Someday, electric-powered transportation will be as common as air.

【推荐2】Gracing every continent of the Earth, wetlands are essential to the planet’s health, often compared to its vital organs, acting as arteries (动脉) that carry water and as kidneys that filter harmful substances.
Wetlands serve as protectors: they form protective barriers against tsunamis and absorb the excess rainfall. During the dry season in dry climates, wetlands release the stored water which helps delay the attack of drought and reduce water shortages. They also store vast quantities of carbon, helping ease climate change. Home to some of the most diverse and rich ecosystems, wetlands support one billion people. 40 percent of all plant and animal species live or breed in wetlands.
World Wetlands Day is observed each year on 2 February to increase people’s understanding of the importance of wetlands and raise awareness of the urgent need to protect the threatened natural treasure.
“We are proud to join in this celebration and recognize the unique and valuable ecosystem services provided by wetlands. We are committed to doing our part to conserve and protect wetlands, and we are calling on all of you to join us in this vital cause,” said UNCCD (The United Nations Convention to Combat Desertification) Executive Secretary Ibrahim Thiaw.
To date, nearly 90 percent of the world’s wetlands have been degraded or lost, with 35 percent in the last 50 years alone. That is why on this World Wetlands Day, UNCCD is joining the Ramsar Convention on Wetlands and other partners to highlight the examples of countries and communities making strides in wetland restoration.
As stressed by the UNCCD Executive Secretary Ibrahim Thiaw, successful wetland restoration requires a joint effort from governments, civil society and the private sector. Investments in science for technology innovation, infrastructure for effective management and financial mechanisms for project implementation (实施) can turn the tide toward a better future for wetlands.

【推荐3】When it comes to President Obama, most of his personal business is already known by the public. Personal information about his children, Malia and Sasha, however, has been kept a little more under wraps.
The New York Times recently released a list of rules that Michelle Obama has mentioned over the years that Malia and Sasha must follow during their time in the White House, as well as in general. See how the first family educates their children:
The girls must write reports about what they’ve seen on their trips, even if it’s not required by their school.
Malia may use her cell phone only on the weekend, and she and her sister cannot watch television or use a computer for anything but homework during the week.
Malia and Sasha have to play two sports: one they choose and one selected by their mother.
Malia must learn to do laundry (洗衣服) before she leaves for college.
The girls have to eat their vegetables, and if they say they are not hungry, they cannot ask for cookies or chips later.
While these might be shocking to some, Michelle said, “They’re not little princesses. It’s just basic rules, boundaries, and expectations that we would have normally.”
Michelle also mentions another set of rules :
The girls must do their chores (家务), though the White House has a large staff. Malia and Sasha have chores of their own.
They must play a team sport, because it’s about learning how to play on a team, how to lose and how to win gracefully.
…
It sounds like Michelle and Barack want the best for their kids and to make them as well rounded as possible. What are your thoughts on the Obama family rules?
