“When inequality increases, people with high incomes don’t benefit much from their gains – many rich people are focused on those who have even more than they do, and they never feel they have enough,”

“But people who earn little really suffer from falling further behind – they feel excluded and frustrated by not being able to keep up even with people who receive average incomes.”

examined survey data of life satisfaction levels, where people rate their life satisfaction on a scale of one to 10, and linked it to Gini coefficient numbers – a measure of inequality – from 1981 to 2020.

In 1981, as the UK was gripped by a recession, life satisfaction stood at 7.7. But during the economic boom of the 1980s, inequality grew, and the research shows that the happiness figure dropped to 7.4 by 1999.

However, as measures to reduce inequality began to take effect, happiness slowly returned so that by 2018, life satisfaction stood at 7.8.

Any country that moved from the lowest quarter of countries in terms of inequality to the highest quarter saw a decrease in life satisfaction of about 0.4 on the 10-point scale, he found.

India’s life satisfaction declined from 6.7 in 1990 to 5.8 in 2006 as inequality rose. By 2012 it was still lower than in 1990, despite the country’s prolonged economic boom.

The US and Australia also both saw pronounced falls in life satisfaction, but those countries where inequality had fallen were generally happier, such as Poland, Peru, Mexico and Ukraine, before the Russian invasion.

“In some of the previous research, you see people saying ‘inequality isn’t that big a deal, so all efforts to address inequality are misguided because inequality is beneficial’.

“I think that’s misguided – inequality is generally damaging to people’s life satisfaction so we should pay attention to efforts to mitigate it,

when Mr. Nichol tweaked his requests a little, adding or subtracting a few words here or there, it provided what he wanted. When he asked for “a piano in a living room filled with sand,” the image looked more like a beach in a living room.

DALL-E is what artificial intelligence researchers call a neural network, which is a mathematical system loosely modeled on the network of neurons in the brain.

the same technology that recognizes the commands spoken into smartphones and identifies the presence of pedestrians as self-driving cars navigate city streets.

A neural network learns skills by analyzing large amounts of data. By pinpointing patterns in thousands of avocado photos, for example, it can learn to recognize an avocado.

DALL-E looks for patterns as it analyzes millions of digital images as well as text captions that describe what each image depicts. In this way, it learns to recognize the links between the images and the words.

Only committed conservatives, the theory goes, would bother to tune in to Sean Hannity or Tucker Carlson, so what difference could it make what they say?

Broockman and Kalla recruited a sample of regular Fox News viewers and paid a subset of them to watch CNN instead.

Then the treatment group of switchers and the control group of non-switchers took three waves of surveys about the news.

The results: Not only did CNN and Fox cover different things during the September 2020 survey period, but the audience of committed Fox viewers, which started the month with conservative predispositions, changed their minds on many issues.

Switchers were five percentage points more likely to believe that people suffer from long Covid, for example, and six points more likely to believe that many foreign countries did a better job than the U.S. of controlling the virus.

They were seven points more likely to support voting by mail. And they were 10 points less likely to believe that supporters of then-candidate Joe Biden were happy when police officers get shot, 11 points less likely to say it’s more important for the president to focus on containing violent protesters than on the coronavirus, and 13 points less likely to agree that if Biden were elected, “we’ll see many more police get shot by Black Lives Matter activists.”

These are meaningful differences, even if the group that switched to CNN remained very right-wing in their view of the American political landscape.

these are reasonably large changes from a one-month experiment. And they occurred despite the long-term effort of then-President Donald Trump to discredit CNN and other mainstream media outlets.

one of the things that switchers changed their minds about was Fox News itself: They became more skeptical that Fox would cover a story that reflected poorly on Trump, even if it were true.

This mode of political influence, where partisan media can simply ignore stories that are inconvenient, is a potentially powerful challenge to democratic accountability.

It’s also probably not symmetrical. Even media outlets that skew liberal in their coverage generally don’t shy away from covering the Covid death toll or the rise in inflation.

one lesson they can take from this experiment is that nobody is impossible to reach.

Broockman and Kalla’s research indicates that information flows at the margin really do matter. Any opportunity to present new facts to people, and new arguments, is valuable.

“It is hard to look at increasing trends in media consumption of all types, media multitasking and rates of ADHD in young people and not conclude that there is a decrease in their attention span,

Emerging research suggests that watching short, fast-paced videos makes it harder for kids to sustain activities that don’t offer instant—and constant—gratification.

One of the few studies specifically examining TikTok-related effects on the brain focused on Douyin, the TikTok equivalent in China, made by the same Chinese parent company, ByteDance Ltd. It found that the personalized videos the app’s recommendation engine shows users activate the reward centers of the brain, as compared with the general-interest videos shown to new users.

Brain scans of Chinese college students showed that areas involved in addiction were highly activated in those who watched personalized videos.

It also found some people have trouble controlling when to stop watching.

attention. “If kids’ brains become accustomed to constant changes, the brain finds it difficult to adapt to a nondigital activity where things don’t move quite as fast,”

A TikTok spokeswoman said the company wants younger teens to develop positive digital habits early on, and that it recently made some changes aimed at curbing extensive app usage. For example, TikTok won’t allow users ages 13 to 15 to receive push notifications after 9 p.m. TikTok also periodically reminds users to take a break to go outside or grab a snack.

Kids have a hard time pulling away from videos on YouTube, too, and Google has made several changes to help limit its use, including turning off autoplay by default on accounts of people under 18.

When kids do things that require prolonged focus, such as reading or solving math problems, they’re using directed attention

This function starts in the prefrontal cortex, the part of the brain responsible for decision making and impulse control.

“Directed attention is the ability to inhibit distractions and sustain attention and to shift attention appropriately. It requires higher-order skills like planning and prioritizing,”

Kids generally have a harder time doing this—and putting down their videogame controllers—because the prefrontal cortex isn’t fully developed until age 25.

“We speculate that individuals with lower self-control ability have more difficulty shifting attention away from favorite video stimulation,

“In the short-form snackable world, you’re getting quick hit after quick hit, and as soon as it’s over, you have to make a choice,” said Mass General’s Dr. Marci, who wrote the new book “Rewired: Protecting Your Brain in the Digital Age.” The more developed the prefrontal cortex, the better the choices.

Dopamine is a neurotransmitter that gets released in the brain when it’s expecting a reward. A flood of dopamine reinforces cravings for something enjoyable, whether it’s a tasty meal, a drug or a funny TikTok video.

“TikTok is a dopamine machine,” said John Hutton, a pediatrician and director of the Reading & Literacy Discovery Center at Cincinnati Children’s Hospital. “If you want kids to pay attention, they need to practice paying attention.”

Researchers are just beginning to conduct long-term studies on digital media’s effects on kids’ brains. The National Institutes of Health is funding a study of nearly 12,000 adolescents as they grow into adulthood to examine the impact that many childhood experiences—from social media to smoking—have on cognitive development.

she predicts they will find that when brains repeatedly process rapid, rewarding content, their ability to process less-rapid, less-rewarding things “may change or be harmed.”

“It’s like we’ve made kids live in a candy store and then we tell them to ignore all that candy and eat a plate of vegetables,”

“We have an endless flow of immediate pleasures that’s unprecedented in human history.”

Parents and kids can take steps to boost attention, but it takes effort

Swap screen time for real time. Exercise and free play are among the best ways to build attention during childhood,

“Depriving kids of tech doesn’t work, but simultaneously reducing it and building up other things, like playing outside, does,”

Practice restraint.

“When you practice stopping, it strengthens those connections in the brain to allow you to stop again next time.”

Use tech’s own tools. TikTok has a screen-time management setting that allows users to cap their app usage.

Ensure good sleep. Teens are suffering from a sleep deficit.
