1 . In the days before the Internet, critical thinking was the most important skill of informed citizens. But in the digital age, according to Anastasia Kozyreva, a psychologist at the Max Planck Institute of Human Development, and her colleagues, an even more important skill is critical ignoring.

As the researchers point out, we live in an attention economy where content producers on the Internet compete for our attention. They attract us with a lot of emotional and eye-catching stories while providing little useful information, so they can expose us to profit-generating advertisements. Therefore,we are no longer customers but products, and each link we click is a sale of our time and attention. Toprotect ourselves from this, Kozyreva advocates for learning the skill of critical ignoring, in which readers intentionally control their information environment to reduce exposure to false and low-quality information.

According to Kozyreva, critical ignoring comprises three strategies. The first is to design ourenvironments, which involves the removal of low-quality yet hard-to-resist information from around. Successful dieters need to keep unhealthy food out of their homes. Likewise, we need to set up a digital environment where attention-grabbing items are kept out of sight. As with dieting, if one tries to bank onwillpower not to click eye-catching “news”, he’ll surely fail. So, it’s better to just keep them out of sightto begin with.

The next is to evaluate the reliability of information, whose purpose is to protect you from false and misleading information. It can be realized by checking the source in the mainstream news agencies which have their reputations for being trustworthy.

The last goes by the phrase “do not feed the trolls.” Trolls are actors who internationally spread false and hurtful information online to cause harm. It may be appealing to respond to them to set the facts straight, but trolls just care about annoying others rather than facts. So, it’s best not to reward their bad behaviour with our attention.

By sharpening our critical ignoring skills in these ways, we can make the most of the Internet while avoiding falling victim to those who try to control our attention, time, and minds.

3 . Every festival has its own meaning. Labor Day, for example, celebrates the value of hard work. Thanksgiving is about showing thanks to people around you. And Valentines’ Day is a time when you express love to your loved ones. But somehow it now seems that all festivals we just care about one thing — shopping. And that can be a big problem.

“In a way, over-consumption (过度消费) is the mother of all our environmental problems,” Kalle Lasn once told CNN. Lasn is the organizer of Buy Nothing Day, a day set up in Canada in 1992 to fight against unhealthy spending habits, and has now become an international event. It’s held on the day, which is known as Black Friday — a famous shopping day in the US and Canada.

You can see the irony (讽刺) here.

Even though the idea of Buy Nothing Day was brought up 26 years ago, we seem to need it now more than ever. It’s just as Lasn said, all the different kinds of pollution in our lives today — bad air quality, the reduction of forest area, endangered animal species, and plastic bags found in the ocean — seem to be the same cause: over-consumption.

The latest example is the Singles’ Day shopping craze of Nov 11, which saw a new sales record. But as Nie Li, a campaigner at Greenpeace, told Reuters, “Record-setting over-consumption means record-setting waste.” And it was reported that last year the Singles’ Day packages left more than 160,000 tons of waste, including plastic and cardboard. The Collins Dictionary has also just named “single-use” its Word of the Year, pointing out the problem that there’re too many things we tow out after only using them once.

So, Buy Nothing Day might only be here for one day a year, but it’s not just to remind us to the a break from shopping on that day, but to change our lifestyle completely, focusing on fun “with people we care about” rather than wasting money on useless things.

6 . One recent report found that adults in the US check their phones, on average, 344 times a day—once every four minutes—and spend almost three hours a day on their devices in total. The problem for many of us is that one quick phone-related task leads to a quick check of our email or social media feeds, and suddenly we’ve been trapped into endless scrolling (刷屏).

What we do know is that the simple distraction of checking a phone or seeing a notification (提示) can have negative consequences. This isn’t very surprising; we know that, in general multitasking harms memory and performance. One of the most dangerous examples is phone use while driving. One study found that merely speaking on the phone, not texting, was enough to make drivers slower to react on the road. It’s true for everyday tasks, too. Simply hearing a notification “ding” made participants of another study perform far worse on a task-almost as badly as participants who were speaking or texting on the phone during the task.

In one recent study, for example, researchers asked participants to either put their phones next to them so they were visible (like on a desk), nearby and out of sight (like in a bag or pocket), or in another room. Participants then completed a series of tasks to test their abilities to process and remember information, their problem-solving, and their focus.

They were found to perform far better when their phones were in another room instead of nearby—whether visible, powered on or not. That held true even though most of the participants claimed not to be consciously thinking about their devices.

Our brains may be subconsciously hard at work in preventing the desire from checking our phones, or constantly monitoring the environment to see if we should check our phone (eg. waiting for a notification). Either way, this distracted attention can make doing anything else more difficult. The only “fix”, the researchers found, was putting the device in a different room entirely.

10 . A short while ago, I lost access to my We Chat account.I am not sure why it wouldn’t let me log in; perhaps it was my ancient, out-of-date phone. But I wasn’t upset because it offered me an opportunity to take a break from social media-something more and more people are doing.

In the United States, Twitter and Facebook has seen a 44 percent decline among its younger users. Stars such as Taylor Swift and Ed Sheeren have taken a break from social media because they were tired of so many Internet trolls leaving negative comments. Ordinary people (like me) are turning away from it because of the feeling that they were spending more time online and enjoying less.

It is not unusual for people to spend two or three hours a day posting or reading posts, to the point where it becomes an addiction.And it is an addiction. There is a chemical in your brain known as dopamine (多巴胺) which is sometimes called the “reward molecule”and its release gives you a feeling of pleasure. For instance, when you post a photo on We Chat and get a hundred likes, you feel happy. That’s dopamine at work.

In my case, being off We Chat is actually an added bonus. No doubt I missed my dopamine. And I got e-mails from friends wondering if I was fine or if I was just being anti-social. But I soon began to feel quite peaceful and started to worry less about what other people were doing and concentrate more on my personal life. And I’m getting better sleep at night.

I’m not advocating that all of you quit social media, but spending less time on these platforms does bring you advantages.
