1 . When making choices, people assume that they pick what they like. However, research suggests that we like something strictly because we have chosen it. In other words, we dislike things we don’t choose. And this phenomenon has existed since we were babies.

In an experiment, US researchers brought several 10 to 20-month-old babies into a lab and gave them two same bright and colorful soft blocks to play with. They set each block far apart, so the babies had to crawl to one or the other—a random choice. After the baby chose one of the toys, the researchers took it away and came back with a new option. The babies could then pick either the toy they didn’t play with before, or a brand-new toy.

It turned out that the babies reliably chose to play with the new toy rather than the one they had not chosen.

In follow-up experiments, when researchers instead helped choose which toy the baby would play with, the phenomenon disappeared. “As if they were saying, ‘Hmm, I didn’t choose that object last time, because I guess I didn’t like it very much” said Lisa Feigenson, co-author of the study.

This is a very important phenomenon in life, Feigenson noted. Adults will less like the thing they didn’t choose, even if they had no real preference in the first place. It looks like babies do just the same.

It shows that the act of making choices changes how we feel about our options. The random choices might become our preferences. “They are really not choosing based on whether they are novel or what they prefer,” said Alex Silver, co-author of the study.

This new finding explains why adults build unconscious preference when they make choices between the same things. Justifying(证明有道理) choice is somehow fundamental to the human experience. “I chose this, so I must like it. I didn’t choose this other thing, so it cannot be so good. Adults make these inferences unconsciously,” Feigenson said.

Such tendency makes sense to us as we live in a consumer culture and must make so many choices every day, between everything from toothpaste brands to styles of jeans.

Next, researchers will look at whether too many choices could be a problem for babies as they certainly are for adults.

3 . Studies have shown most people fail to realise how much time they spend on their smartphones each day.

Frank and Amelia’s family were put to a test, using a free app called “Moment-Screen Time Tracker”. The Vascellaros—Frank, Amelia, 14-year-old twins Frankie and Joe, and 17-year-old Sam—all said they did not really know they were spending so much time on their phones each day.

“Honestly, I don’t feel like I’m on my phone a lot,” Amelia Vascellaro said. Amelia was on her phone far less often than Frank, according to the app. While Amelia spent about an hour per day on the phone, Frank spent closer to four hours on his phone, which came as a shock to him. The children’s times varied but they often spent more than a couple of hours on the phone as well.

Minneapolis-based Dr. Kirsten Lind Seal sees phone usage come up lot among families. Lind Seal said many family members’ phone use has become problematic.

“If we hear more than once, ‘Do you have to be on your phone right now? Can you please put your phone down? Did you hear what I said?’ it may be a sign that it is negatively influencing our family relationships and our daily lives,” she said.

Lind Seal said actually paying attention to how much time one spends on the phone is a good first step in deciding when to put it down.

She asks parents to encourage more face-to-face communication for teens and young adults as they continue developing their social and emotional skills. “What we find is that we are really losing out on empathy—the ability to understand other people’s feelings and problems—when we spend a lot of time on our smartphones to communicate with other people,” she said.

5 . A books-for-food program in Guatemala is helping feed needy children as hunger rates rise during the pandemic(疫情). It is run by a local nonprofit organization that aims to feed nearly 400 children.

The program is simple. People choose a book they want from a list of donated titles, and in return give bags of Incaparina, a high-protein drink mix. Bonifaz Diaz works for the program. By bringing the books-for-food program directly to people's homes, Diaz makes sure donations keep flowing. He has traveled more than 2,000 kilometers on his bicycle, delivered loads of books and carried back thousands of kilograms of Incaparina for the nonprofit group 32 Volcanoes. Diaz sometimes pulls a small cart that helps him carry up to 57 kilograms of product. He has traveled as far as 60 kilometers for a delivery to a town in the Western Highlands, where road conditions are poor.

Nearly a year into the books-for-food program, two more cyclists have joined Diaz and donations keep flowing in. Ana Castillo is a 29-year-old high school teacher who recently received the sociology book from Diaz. She donates to the program often. The 1.8 kilograms of Incaparina she provided will help one family eat for a month.

Castillo looks forward to choosing her books from the titles Diaz posts on social media. She also loves the feeling of a "growing circle" of giving and receiving. "You might not get to those places, but your help can. "she says.

Diaz says he plans to continue cycling against hunger as long as the need exists. He has faced his own economic difficulties since the theater company he co-founded closed last spring. But the program has kept him active. "It's an opportunity to serve in which we all benefit. "Diaz said.

7 . Twenty-five years ago, most young Britons wanted a career in law, to be a doctor, or, if they were creatively minded, to take up singing. But today, things stand differently.

According to a survey by Tesco Mobile, a UK telecoms company, the “dream job” of young people aged between 16 and 25 in the UK is a video blogger, or “vlogger”. The survey, carried out among 1 , 002 people, found that as much as 40 percent of them put vlogger as their number one choice on a list of ideal jobs.

The only reason for this change is undoubtedly the Internet and social media. They have made it so much easier to reach a global user, without having to get a job in show business in the traditional way.

“In years gone by, the biggest stars were shaped and trained by the Hollywood studios； now, anyone with a computer camera can become an icon (偶像)，" a Tesco Mobile spokesperson said in a news release(发布会).“These self-made stars record their hobbies to an admiring fan-base. Vloggers are the big stars of today because they are normal people interacting with their fans about everyday life.”

However, what people see is only the great side of being a vlogger and they ignore the fact that only those who are successful get fame and fortune. There are the dreams that come true and the dreams that still remain dreams.

This is why although vloggers are popular, some young people choose jobs that don't necessarily earn them fame, but allow them to make good use of the Internet to share their hobbies. Young Israeli David Leshaw, for example, runs a business called the Finishers Club. It's an online platform(平台)for runners to keep a record of their races. He told the website Zippia that his job allows him to express his thought, and is always a learning experience. And that's enough for him.

8 . One Moore Elementary school teacher is showing students the importance of communication through “shout-outs”. Third Grade Moore Elementary Teacher Lindsey Winders said a shout-out is a compliment(称赞) that students can say or write down. “Like, ‘hey I noticed you doing a really great job solving your math problems yesterday. I wanted to make sure you know that I saw you do that,’” Winders said.

Winders said she makes sure she is giving shout-outs to her students every day. “I might write them a sticky note, or write them a quick little note in their planner. I might just say it to them on their way into the classroom or on their way out of the classroom, but most importantly I try to do it every day,” Winders said.

In addition to the compliments, Winders has the students greet(问候) each other every morning during morning meeting. She will have students give examples to the class of how to communicate in different settings(场景). Third grade student Nayelli Moranchel said she had given at least six shout-outs this year. “It makes me happy, because they always write something back,” Moranchel said.

Recently, Winders took it one step further and wrote a personalized note on each of her students’ desk. “In our classroom, sometimes it can be challenging for me to give a compliment or a shout-out to each and every one of them in a way that feels equal(平等的) and valuable at the same time. So I decide that there is no better way than leaving a note on their desk that can stay for as long as they wants it to,” Winders said.

Winders said it is encouraging when she sees her students copy the act, and give each other compliments without her guidance(指导).
