3 . People tend to cut corners and allow trusted workmates to do their work when working as a team. Now researchers have found that the same thing happens when humans work with robots.

Dietlind Cymek at the Technical University of Berlin in Germany and her colleagues designed an experiment to test whether humans would put in less effort when they think that their personal contribution to a task won’t be noticed.

In the experiment, the researchers asked a group of 42 people to examine images of circuit boards (电路板) for errors using a computer that tracked their work. Half of them looked at boards that had already been checked by a robot, and half were told that they were the only ones responsible for quality control.

People working in partnership with the robot caught fewer errors, after they had already seen that the robot had successfully flagged lots of errors.

The researchers say such teamwork could lead to a drop in motivation if individual effort isn’t visible and warn that there could be safety risks if teams of people and robots work on safety-related tasks in the same way.

Kathleen Richardson at De Montfort University in Leicester, UK, says it is fine to use robots as long as they are effective, but that they should be considered tools rather than workmates or team members. “It just strikes me that workers think when a tool can do something, they let it,” says Richardson.

This is probably down to poor management style, in which individual work isn’t recognised. “I bet you if there was an motivation behind it, and if the humans could get extra pay for spotting errors in the circuit boards, then they’d put a bit more effort into it,” she adds.

4 . It was reported that a worker’s strike happened because industry bosses are planning to cancel paper tickets and close almost 1,000 station ticket offices in England. The government says nothing has been decided in reply to this strike. But some officials advise to save money in this way.

Regardless of the outcome of the strike, the direction of digital change is clear. With time going by, station ticket offices are likely to become a sepia-tinted memory. For us, we who have been used to organising travel via a smartphone feel little sadness. But for people without online skills — who may be older, poorer and weaker — another small social barrier will be built.

From doctor appointments to payment apps, more and more key services are now provided online. Local government, lack of money, has to do business in this way. As this change takes place, some people hold that it can be unfair to some users. In the case of health and social care, those who need help most are unable to navigate (导航) a digital route to the place. A recent report estimated that around 6% of households have no internet access. As digital technology becomes the gatekeeper to everyday life, some groups may face the problem of exclusion and isolation.

The debate over ticket offices offers an opportunity to reflect on the increasing role of technology in our society. Clearly, it is important to help marginalised groups gain easy online access. Some people will never become comfortable using smartphones or tablets. Some offline options must be maintained for important services. This will cost more. But that is the price of being fair to those who find themselves on the wrong side of the digital divide.

5 . As athletes get stronger and faster, the pace of play continues to increase. The burden of making sure games are played according to the rules and that the officiating (裁判) is accurate is now being taken out of human hands and falling more and more into the lap of technology. It’s called the video replay.

The National Football League is expanding its replay system this upcoming season to include pass interference (传球干扰). Major League Baseball now relies on it for safe-or-out and home run calls. If you’ve been watching the FIFA World Cup, you may have noticed that the Video Assistant Referee (VAR) played a key role in almost every game. And in the Kentucky Derby, a horse was disqualified for knocking another horse. No one knew why until a video replay confirmed the call and controversy was avoided.

However, many purists—those who want people to follow rules carefully and do things in the traditional way—especially in soccer, argue it’s not the way the game was invented, and that the video replay is tainting the sport. But don’t you want to see the proper application of the rules throughout the games? I know I do. Yes, it can slow the game down, but I feel it is worth it. If technological advancements allow fans watching from home to spot mistakes instantly, those same views need to be available to the officiating crews. Another example occurred in the most recent National Football Conference (NFC) Championship Game between the Los Angeles Rams and the New Orleans Saints. When obvious pass interference was committed by the Los Angeles Rams player Nickell Robey-Coleman, with just 109 seconds to play, no flag was raised on the field. It weakened the New Orleans Saints spirits. The Los Angeles Rams won a 26-23 overtime victory. The no-call deeply angered the public. The video replay showed the referees had just missed one of the most apparent pass interference calls.

There are no easy answers regarding replay technology and whether it is a curse (魔咒). But for me, keeping the officiating honest and on task is the right step in limiting controversy.

6 . Parents have been urged to stop pretending Father Christmas is real in case the “lie” damages relations with their children. Making up stories about Santa risks destroying a child’s trust and is morally unbelievable, according to two experts.

Psychologist Professor Christopher Boyle and social scientist Dr. Kathy McKay also criticize the idea employed by parents—Santa Claus judges children to be nice or naughty. Writing in a well-known journal, they argue, “If they are capable of lying about something so special and magical, can they be relied upon to continue as the guardians of wisdom and truth?”

Defending the claims, Prof Boyle said, “The morality of making children believe in such myths has to be questioned. All children will eventually find out they’ve been consistently lied to for years, and this might make them wonder what other lies they’ve been told. Whether it’s right to make children believe in Father Christmas is an interesting question, and it’s also interesting to ask whether lying in this way will affect children in ways that have not been considered.”

Dr. McKay, from the University of New England in Australia, said there was clear evidence from the world of make-believe in movies and TV that adults looked for a chance to be children again. “The persistence of fandom(影迷) in stories like Harry Potter and Star Wars indicates their desire to briefly re-enter childhood,” she said. “However,” she added, “if adults have been lying about Santa, even though it has usually been well intentioned, what else is a lie? If Santa isn’t real, are fairies real? Is magic? Is God?”

They conclude, “Many people may long for a time when imagination was accepted and encouraged, which may not be the case in adult life. Might it be the case that the harshness of real life requires the creation of something better, something to believe in, something to hope for in the future or to return to a long-lost childhood a long time ago in a galaxy far far away?”

7 . If you only have a few close friends, you may feel like an outcast in society. However, studies show that loners typically have greater intelligence than popular folks. So, if you prefer being alone most of the time, don’t beat yourself up about it.

Evolutionary psychologists Satoshi Kanazawa and Norman Li conducted a national survey involving 15,000 respondents aged from 18 to 28. The research revealed that people who lived in densely populated urban areas reported lower life satisfaction in general and that the more people socialized with close friends, the higher their self-reported happiness was. Of course, the only exception occurred when it came to intelligent individuals.

“The effect of population density on life satisfaction was therefore more than twice as large for low-IQ individuals than for high-IQ individuals,” they found. More intelligent individuals were actually less satisfied with life if they socialized with their friends more frequently. In other words, when intelligent people hang out more with their friends, they feel less happy.

What makes highly intelligent people so different from the average person? They prefer to spend their time alone usually because they have a larger goal in mind. They see socializing as a distraction when they could use their time more wisely. Also, they don’t appear to be as sensitive to population density as those with lower IQs. Therefore, they can navigate the challenges of modern living more efficiently and perhaps find novel solutions to most significant problems.

According to Kanazawa and Li’s savanna theory of happiness (稀树草原幸福理论), in the past, we would have lived in tribes instead of densely populated cities, helping to avoid loneliness. “Our ancestors lived as hunter-gatherers in small bands of about 150 individuals,” they explain. “In such settings, having frequent contact with friends was necessary for their survival.” While we no longer live in small tribes now, most of us still require close friends and family to survive. That may explain the epidemic of loneliness affecting millions of people worldwide.

However, highly intelligent people are the exception to this theory. They don’t mind spending most of their time alone. So, if you don’t have many friends, you may have learned to overcome your primitive instincts. Perhaps you represent this small group of humans who can thrive in the modern era.

8 . My grandparents were always busy with food. My grandmother could pull out the feathers of a chicken in less than half an hour. They picked vegetables from their garden. Animal fat was saved.     1     Nearly a decade after my grandmother died, I found myself in a kitchen, pulling out the feathers of a chicken.

It took hours and made my fingers hurt. After an adult life spent buying rather than growing food, as a so-called new farmer, I finally began to understand my grandparents.     2    

My grandparents’ generation spent a third of their income on food.     3     Food is no longer seen as public goods, but as public given resources. The ecological cost of this progress is now clear. The health costs are starting to be noticed.

But until I began talking to the farmers around me, I had not understood the human costs faced by those asked to produce milk sold for less than bottled water.     4     Called “ regenerative farming”, it was being driven by a new generation of farmers trying to find a new kind of power in the face of loss of climate change and rising fuel and transport costs.

    5     Those plants and animals worked together to help the soil become rich again. They kept living roots in the ground all year round, building up the soil’s biology and taking in carbon.

Research has found that regenerative farming not only benefits the land, but profits can be 78% higher than conventional farms.
