Consider a common diagnostic question used to help identify addiction, such as “I always use X to relax after a bad day.” Well, if X is methamphetamine, that’s a worrisome choice, one that presumably indicates addiction. But if X is playing video games, how is that different from unwinding after work by knitting, watching sports or playing bridge?

Taste does not simply equal your taste buds. It draws on information from all our senses as well as context. As a result, food is susceptible to the same trickery as wine. Adding yellow food dye to vanilla pudding leads people to experience a lemony taste. Diners eating in the dark at a chic concept restaurant confuse veal for tuna. Branding, packaging, and price tags are equally important to enjoyment. Cheap fish is routinely passed off as its pricier cousins at seafood and sushi restaurants. 

Just like with wine and classical music, we often judge food based on very different criteria than what we claim. The result is that our perceptions are easily skewed in ways we don’t anticipate. 

What does it mean for wine that presentation so easily trumps the quality imbued by being grown on premium Napa land or years of fruitful aging? Is it comforting that the same phenomenon is found in food and classical music, or is it a strike against the authenticity of our enjoyment of them as well? How common must these manipulations be until we concede that the influence of the price tag of a bottle of wine or the visual appearance of a pianist is not a trick but actually part of the quality?

To answer these questions, we need to investigate the underlying mechanism that leads us to judge wine, food, and music by criteria other than what we claim to value. And that mechanism seems to be the quick, intuitive judgments our minds unconsciously make

this unknowability also makes it easy to be led astray when our intuition makes a mistake. We may often be able to count on the price tag or packaging of food and wine for accurate information about quality. But as we believe that we’re judging based on just the product, we fail to recognize when presentation manipulates our snap judgments.

Participants were just as effective when watching 6 second video clips and when comparing their ratings to ratings of teacher effectiveness as measured by actual student test performance. 

The power of intuitive first impressions has been demonstrated in a variety of other contexts. One experiment found that people predicted the outcome of political elections remarkably well based on silent 10 second video clips of debates - significantly outperforming political pundits and predictions made based on economic indicators.

In a real world case, a number of art experts successfully identified a 6th century Greek statue as a fraud. Although the statue had survived a 14 month investigation by a respected museum that included the probings of a geologist, they instantly recognized something was off. They just couldn’t explain how they knew.

Cases like this represent the canon behind the idea of the “adaptive unconscious,” a concept made famous by journalist Malcolm Gladwell in his book Blink. The basic idea is that we constantly, quickly, and unconsciously do the equivalent of judging a book by its cover. After all, a cover provides a lot of relevant information in a world in which we don’t have time to read every page.

Gladwell describes the adaptive unconscious as “a kind of giant computer that quickly and quietly processes a lot of the data we need in order to keep functioning as human beings.”

In a famous experiment, psychologist Nalini Ambady provided participants in an academic study with 30 second silent video clips of a college professor teaching a class and asked them to rate the effectiveness of the professor.

In follow up experiments, Chia-Jung Tsay found that those judging musicians’ auditions based on visual cues were not giving preference to attractive performers. Rather, they seemed to look for visual signs of relevant characteristics like passion, creativity, and uniqueness. Seeing signs of passion is valuable information. But in differentiating between elite performers, it gives an edge to someone who looks passionate over someone whose play is passionate

Outside of these more eccentric examples, it’s our reliance on quick judgments, and ignorance of their workings, that cause people to act on ugly, unconscious biases

It’s also why - from a business perspective - packaging and presentation is just as important as the good or service on offer. Why marketing is just as important as product. 

Gladwell ends Blink optimistically. By paying closer attention to our powers of rapid cognition, he argues, we can avoid its pitfalls and harness its powers. We can blindly audition musicians behind a screen, look at a piece of art devoid of other context, and pay particular attention to possible unconscious bias in our performance reports.

But Gladwell’s success in demonstrating how the many calculations our adaptive unconscious performs without our awareness undermines his hopeful message of consciously harnessing its power.

As a former world-class tennis player and coach of over 50 years, Braden is a perfect example of the ideas behind thin slicing. But if he can’t figure out what his unconscious is up to when he recognizes double faults, why should anyone else expect to be up to the task?

flawed judgment in fields like medicine and investing has more serious consequences. The fact that expertise is so tricky leads psychologist Daniel Kahneman to assert that most experts should seek the assistance of statistics and algorithms in making decisions.

In his book Thinking, Fast and Slow, he describes our two modes of thought: System 1, like the adaptive unconscious, is our “fast, instinctive, and emotional” intuition. System 2 is our “slower, more deliberative, and more logical” conscious thought. Kahneman believes that we often leave decisions up to System 1 and generally place far “too much confidence in human judgment” due to the pitfalls of our intuition described above.

Not every judgment will be made in a field that is stable and regular enough for an algorithm to help us make judgments or predictions. But in those cases, he notes, “Hundreds of studies have shown that wherever we have sufficient information to build a model, it will perform better than most people.”

Experts can avoid the pitfalls of intuition more easily than laypeople. But they need help too, especially as our collective confidence in expertise leads us to overconfidence in their judgments. 

This article has referred to the influence of price tags and context on products and experiences like wine and classical music concerts as tricks that skew our perception. But maybe we should consider them a real, actual part of the quality.

Losing ourselves in a universe of relativism, however, will lead us to miss out on anything new or unique. Take the example of the song “Hey Ya!” by Outkast. When the music industry heard it, they felt sure it would be a hit. When it premiered on the radio, however, listeners changed the channel. The song sounded too dissimilar from songs people liked, so they responded negatively. 

It took time for people to get familiar with the song and realize that they enjoyed it. Eventually “Hey Ya!” became the hit of the summer.

Many boorish people talking about the ethereal qualities of great wine probably can't even identify cork taint because their impressions are dominated by the price tag and the wine label. But the classic defense of wine - that you need to study it to appreciate it - is also vindicated. The open question - which is both editorial and empiric - is what it means for the industry that constant vigilance and substantial study is needed to dependably appreciate wine for the product quality alone. But the questions is relevant to the enjoyment of many other products and experiences that we enjoy in life.

Maybe the most important conclusion is to not only recognize the fallibility of our judgments and impressions, but to recognize when it matters, and when it doesn’t

Investment is usually the result of forgoing consumption. In a purely agrarian society, early humans had to choose how much grain to eat after the harvest and how much to save for future planting. The latter was investment.

In a more modern society, we allocate our productive capacity to producing pure consumer goods such as hamburgers and hot dogs, and investment goods such as semiconductor foundries. If we create one dollar worth of hamburgers today, then our gross national product is higher by one dollar.

Investment need not always take the form of a privately owned physical product. The most common example of nonphysical investment is investment in human capital.

In an economy that is closed to the outside world, investment can come only from the forgone consumption—the saving—of private individuals, private firms, or government.

In an open economy, however, investment can surge at the same time that a nation’s saving is low because a country can borrow the resources necessary to invest from neighboring countries.

That economists have a fairly strong understanding of firms’ investment behavior makes sense. A firm that maximizes its profits must address investment using the framework discussed in this article.

The theory of investment dates back to the giants of economics. irving fisher, arthur cecil pigou, and alfred marshall all made contributions; as did john maynard keynes, whose Marshallian user cost theory is a central feature in his General Theory.

Investment fluctuates a lot because the fundamentals that drive investment—output prices, interest rates, and taxes—also fluctuate. But economists do not fully understand fluctuations in investment. Indeed, the sharp swings in investment that occur might require an extension to the Jorgenson theory.

In Jorgenson’s user cost model, firms will purchase a machine if the extra revenue the machine generates is a smidgen more than its cost.

The general conclusion is that there is a gain to waiting if there is uncertainty and if the installation of the machine entails sunk costs, that is, costs that cannot be recovered once spent.

Although quantifying this gain exactly is a highly mathematical exercise, the reasoning is straightforward. That would explain why firms typically want to invest only in projects that have a high expected profit.

The fact of irreversibility might explain the large fluctuations in investment that we observe.

This method of financing investment has been very important in the United States. The industrial base of the United States in the nineteenth century—railroads, factories, and so on—was built on foreign finance, especially from Britain. More recently, the United States has repeatedly posted significant investment growth and very low savings.

Consumer behavior is harder to study than firms’ behavior. Market forces that drive irrational people out of the marketplace are much weaker than market forces that drive bad companies from the market.

Because the saving response of consumers must be known if one is to fully understand the impact of any investment policy, and because saving behavior is so poorly understood, much work remains to be done.

Eager to finally cook food of my own, I decided to pick up groceries at the King Soopers on Table Mesa Drive.

I spent most of my first solo supermarket store trip asking the store attendants where various items were.

Right away I was struck by how welcoming and friendly everyone working there was.

Teri Leiker, killed in Monday’s massacre, was the employee who packed groceries into my large duffle bag. “Find everything all right?” she asked with a grin. “You could pack this thing three times over,” she added, when zipping up my bag.

My interaction with Teri was representative of the warm vibe and casual relationship I developed with many of the store employees.

Rikki Olds, also murdered in the shooting, came to the rescue several times when my self-checkout machine froze

, and assured me it was fine when I realized I forgot things on my shopping list halfway through scanning items.

Shootings have become an all-too-common occurrence in America.

serving as a stark reminder that at any moment Boulder could be the next target of domestic terrorism.

As much as a mass shooting remained a lingering possibility, never did anyone expect something of Monday’s magnitude to occur in a peaceful, quirky, happy-go-lucky college town that’s proudly advertised itself as one of the best places to live in the country.

I was hit with a sense of guilt knowing I had never fully expressed my gratitude for Teri or Rikki’s hard work and compassion.

Never did I take a second to stop and think about the role they and their co-workers played in making me comfortable in a new place and transitioning to adulthood.

Going forward, we owe it to ourselves to have an enhanced appreciation of life and treat one another more kindly

In honor of the 10 people caught in the middle of another senseless shooting, let’s all strive to be more appreciative.

Postman also recognised that technology was changing our mental processes and social habits.

Today corporations like Google and Amazon collect data on Internet users based on their browsing history, the things they purchase, and the apps they use

Yet all citizens are undergoing this same transformation. Our digital devices undermine social interactions by isolating us,

“Years from now, it will be noticed that the massive collection and speed-of-light retrieval of data have been of great value to large-scale organisations, but have solved very little of importance to most people, and have created at least as many problems for them as they may have solved.”

“Television has by its power to control the time, attention, and cognitive habits of our youth gained the power to control their education.”

As a student of Canadian philosopher Marshall McLuhan, Postman believed that the medium of information was critical to understanding its social and political effects. Every technology has its own agenda. Postman worried that the very nature of television undermined American democratic institutions.

Many Americans tuned in to the presidential debate looking for something substantial and meaty

It was simply another manifestation of the incoherence and vitriol of cable news

“When, in short, a people become an audience and their public business a vaudeville act, then a nation finds itself at risk; culture-death is a clear possibility,” warned Postman.

Technology Is Never Neutral

As for new problems, we have increased addictions (technological and pornographic); increased loneliness, anxiety, and distraction; and inhibited social and intellectual maturation.

The average length of a shot on network television is only 3.5 seconds, so that the eye never rests, always has something new to see. Moreover, television offers viewers a variety of subject matter, requires minimal skills to comprehend it, and is largely aimed at emotional gratification.

This is far truer of the Internet and social media, where more than a third of Americans, and almost half of young people, now get their news.

with smartphones now ubiquitous, the Internet has replaced television as the “background radiation of the social and intellectual universe.”

Is There Any Solution?

Reading news or commentary in print, in contrast, requires concentration, patience, and careful reflection, virtues that our digital age vitiates.

Politics as Entertainment

“How television stages the world becomes the model for how the world is properly to be staged,” observed Postman. In the case of politics, television fashions public discourse into yet another form of entertainment

In America, the fundamental metaphor for political discourse is the television commercial. The television commercial is not at all about the character of products to be consumed. … They tell everything about the fears, fancies, and dreams of those who might buy them.

The television commercial has oriented business away from making products of value and towards making consumers feel valuable, which means that the business of business has now become pseudo-therapy. The consumer is a patient assured by psycho-dramas.

Such is the case with the way politics is “advertised” to different subsets of the American electorate. The “consumer,” depending on his political leanings, may be manipulated by fears of either an impending white-nationalist, fascist dictatorship, or a radical, woke socialist takeover.

This paradigm is aggravated by the hypersiloing of media content, which explains why Americans who read left-leaning media view the Proud Boys as a legitimate, existential threat to national civil order, while those who read right-leaning media believe the real immediate enemies of our nation are Antifa

Regardless of whether either of these groups represents a real public menace, the loss of any national consensus over what constitutes objective news means that Americans effectively talk past one another: they use the Proud Boys or Antifa as rhetorical barbs to smear their ideological opponents as extremists.

Yet these technologies are far from neutral. They are, rather, “equipped with a program for social change.

Postman’s analysis of technology is prophetic and profound. He warned of the trivialising of our media, defined by “broken time and broken attention,” in which “facts push other facts into and then out of consciousness at speeds that neither permit nor require evaluation.” He warned of “a neighborhood of strangers and pointless quantity.”

does Postman offer any solutions to this seemingly uncontrollable technological juggernaut?

Postman’s suggestions regarding education are certainly relevant. He unequivocally condemned education that mimics entertainment, and urged a return to learning that is hierarchical, meaning that it first gives students a foundation of essential knowledge before teaching “critical thinking.”

Postman also argued that education must avoid a lowest-common-denominator approach in favor of complexity and the perplexing: the latter method elicits in the student a desire to make sense of what perplexes him.

Finally, Postman promoted education of vigorous exposition, logic, and rhetoric, all being necessary for citizenship

Another course of action is to understand what these media, by their very nature, do to us and to public discourse.

We must, as Postman exhorts us, “demystify the data” and dominate our technology, lest it dominate us. We must identify and resist how television, social media, and smartphones manipulate our emotions, infantilise us, and weaken our ability to rebuild what 2020 has ravaged.

The World Mosquito Program (WMP), a nonprofit that pioneered this technique, had run small pilot studies in Australia that suggested it could work. Utarini, who co-leads WMP Yogyakarta, has now shown conclusively that it does.

Carried around the world aboard slave ships, Aedes aegypti has thrived. It is now arguably the most effective human-hunter on the planet, its senses acutely attuned to the carbon dioxide in our breath, the warmth of our bodies, and the odors of our skin.

Wolbachia was first discovered in 1924, in a different species of mosquito. At first, it seemed so unremarkable that scientists ignored it for decades. But starting in the 1980s, they realized that it has an extraordinary knack for spreading. It passes down mainly from insect mothers to their children, and it uses many tricks to ensure that infected individuals are better at reproducing than uninfected ones. To date, it exists in at least 40 percent of all insect species, making it one of the most successful microbes on the planet.

The team divided a large portion of the city into 24 zones and released Wolbachia-infected mosquitoes in half of them. Almost 10,000 volunteers helped distribute egg-filled containers to local backyards. Within a year, about 95 percent of the Aedes mosquitoes in the 12 release zones harbored Wolbachia.

The team found that just 2.3 percent of feverish people who lived in the Wolbachia release zones had dengue, compared with 9.4 percent in the control areas. Wolbachia also seemed to work against all four dengue serotypes, and reduced the number of dengue hospitalizations by 86 percent.

Even then, these already remarkable numbers are likely to be underestimates. The mosquitoes moved around, carrying Wolbachia into the 12 control zones where no mosquitoes were released. And people also move: They might live in a Wolbachia release zone but be bitten and infected with dengue elsewhere. Both of these factors would have worked against the trial, weakening its results

The Wolbachia method does have a few limitations. The bacterium takes months to establish itself, so it can’t be “deployed to contain an outbreak today,” Vazquez-Prokopec told me. As the Yogyakarta trial showed, it works only when Wolbachia reaches a prevalence of at least 80 percent, which requires a lot of work and strong community support

The method has other benefits too. It is self-amplifying and self-perpetuating: If enough Wolbachia-infected mosquitoes are released initially, the bacterium should naturally come to dominate the local population, and stay that way. Unlike insecticides, Wolbachia isn’t toxic, it doesn’t kill beneficial insects (or even mosquitoes), and it doesn’t need to be reapplied, which makes it very cost-effective.

An analysis by Brady’s team showed that it actually saves money by preventing infections

Wolbachia also seems to work against the other diseases that Aedes aegypti carries, including Zika and yellow fever. It could transform this mosquito from one of the most dangerous species to humans into just another biting nuisance.

language skills.

They were tested once and then again an average of 1.7 years later.

Researchers tested memory skills of the people with primary progressive aphasia by showing them pictures of common objects. After waiting 10 minutes, they were shown the same pictures along with others and had to indicate whether they had seen the picture before. This test was given once and then again an average of 2.4 years later.

their verbal memory and language skills declined with equal severity during the study.

Left sided asymmetry of brain shrinkage and a lower incidence of brain proteins known as ApoE4 and TDP-43 were identified as potential contributors to the preservation of memory in this rare type of Alzheimer's disease.

Limitations of the study are the relatively small sample size and that autopsies were not available for all of the primary progressive aphasia cases.

hus Copernicus started to look for something simpler, almost at the same time that Michelangelo undertook another great project, that of decorating the ceiling of the Sistine Chapel.

Copernicus had a full Renaissance résumé: studies in medicine, art, mathematics, canon law and philosophy; experience as an economist and a diplomat; and also a good position as an ecclesiastical official.

By 1514, he had already written a sketch of his theory, although he did not publish it for fear of being condemned as a heretic and also because he was a perfectionist. He spent 15 more years repeating his calculations, diagrams and observations with the naked eye, prior to the invention of the telescope.

Copernicus was the first to recite them in order: Mercury, Venus, Earth, Mars, Jupiter and Saturn, the 6 planets that were then known.

When Copernicus finally decided to publish his theory, the book’s publisher softened it in the prologue: he said that there were “only easier mathematics” for predicting the movements of the planets, and not a whole new way of looking at the reality of the universe. But this was understood as a challenge to Aristotle, to the Church, and to common sense.

It would be 150 years before the Copernican revolution triumphed, and the world finally admitted that the Earth was just one more spinning top.

it’s good to know about your environment even if it doesn’t promise a reward right now; knowledge may be useless today, but vital next week. Therefore, evolution has left us with a brain that can reward itself; satisfying curiosity feels pleasurable, so you explore the environment even when you don’t expect any concrete payoff

What’s more, curiosity doesn’t just ensure new opportunities for learning, it enhances learning itself

subjects better remembered those appearing after trivia questions that made them curious. Curiosity causes a brain state that amplifies learning.

This function of curiosity — to heighten memory — is the key to understanding why we’re curious about some things and not others. We feel most curious when exploration will yield the most learning.

Suppose I ask you, “What’s the most common type of star in the Milky Way?” You’ll obviously feel no curiosity if you already know the answer. But you’ll also feel little interest if you know nothing about stars; if you learned the answer, you couldn’t connect it to other knowledge, so it would seem nearly meaningless, an isolated factoid

We’re maximally curious when we sense that the environment offers new information in the right proportion to complement what we already know.

Note that your brain calculates what you might learn in the short term — your long-term interests aren’t a factor

Many websites that snare your time feature scores of stories on the front page, banking that one will strike each reader’s sweet spot of knowledge. So visit websites that use the same strategy but offer richer content, for example, JSTOR Daily, Arts & Letters Daily or ScienceDaily.

Curiosity arises from the right balance of the familiar and the novel. Naturally, writers vary in what they assume their audience already knows and wants to know; when you find an author who tends to have your number, stick with her.

According to Common Sense Media, teens spend an average of nine hours a day online (paywall), compared to about six hours for those aged eight to 12 and 50 minutes for kids between 0 and eight

“It’s not a drug, but it might as well be. It works the same way… it has the same results,

A startling 44% of teens tell Pew that they often check their phones for messages or notifications as soon as they wake up; 28% say they check at least sometimes.

After discussing the common psychological patterns that unfold in inmates, Frankl is careful to challenge the assumption that human beings are invariably shaped by their circumstances.

If there is a meaning in life at all, then there must be a meaning in suffering. Suffering is an ineradicable part of life, even as fate and death. Without suffering and death human life cannot be complete.

“When a driver cuts you off on the highway and your blood begins to boil, it’s your prefrontal cortex that allows you to think, ‘Wait a minute, I don’t have to act this way,’”

But the prefrontal cortex doesn’t fully develop until adulthood and, according to Dr. Fields, inhibition and impulse control are among the PFC’s most complicated functions. “So when you try to reason with a child, you’re appealing to a part of the brain that isn’t fully functioning.”

Watching someone run, for instance, seems to activate a similar brain region as when you run yourself.

For example, mirror neurons have been found not only in the motor areas of the brain, but also in the areas that deal with emotion. The same part of your brain that lights up when you’re feeling happy may also light up when you observe happiness in others.

As much as you might want to try explaining to your kid why they should calm down, behavior correction rarely works when stress is high.

But as a parent, I’ve experienced another level of perception that seems to kick in with no clear outside cues

“The only really valuable thing is intuition,” Albert Einstein said

We are connected to our offspring on a level so deep that it sometimes defies reason. What are the possibilities of parental premonition? Is intuition underused and even unfairly maligned?

But I’ve been reminded again in recent weeks that yet tempering that common sense with some trust in gut might be the most useful advice we can get.

we might do well to heed our intuition, give it its due, and even discuss it among ourselves as parents. It could be one more tool — and perhaps an extremely powerful one — in our parental toolbox.

If you’ve got as little as 30 seconds and a decent internet connection, you can help combat the deforestation of the Amazon. 

to build an artificial intelligence model that can recognize signs of deforestation. That data can be used to alert governments and conservation organizations where intervention is needed and to inform policies that protect vital ecosystems. It may even one day predict where deforestation is likely to happen next.

To monitor deforestation, conservation organizations need an eye in the sky.

WRI’s Global Forest Watch online tracking system receives images of the world’s forests taken every few days by NASA satellites. A simple computer algorithm scans the images, flagging instances where before there were trees and now there are not. But slight disturbances, such as clouds, can trip up the computer, so experts are increasingly interested in using artificial intelligence.

Inman was surprised how willing people have been to spend their time clicking on abstract-looking pictures of the Amazon.

Look at these nine blocks and make a judgment about each one. Does that satellite image look like a situation where human beings have transformed the landscape in some way?” Inman explained.

It’s not always easy; that’s the point. For example, a brown patch in the trees could be the result of burning to clear land for agriculture (earning a check mark for human impact), or it could be the result of a natural forest fire (no check mark). Keen users might be able to spot subtle signs of intervention the computer would miss, like the thin yellow line of a dirt road running through the clearing. 

SAS’s website offers a handful of examples comparing natural forest features and manmade changes. 

users have analyzed almost 41,000 images, covering an area of rainforest nearly the size of the state of Montana. Deforestation caused by human activity is evident in almost 2 in 5 photos.

The researchers hope to use historical images of these new geographies to create a predictive model that could identify areas most at risk of future deforestation. If they can show that their AI model is successful, it could be useful for NGOs, governments and forest monitoring bodies, enabling them to carefully track forest changes and respond by sending park rangers and conservation teams to threatened areas. In the meantime, it’s a great educational tool for the citizen scientists who use the app

Users simply select the squares in which they’ve spotted some indication of human impact: the tell-tale quilt of farm plots, a highway, a suspiciously straight edge of tree line. 

we have still had people from 80 different countries come onto the app and make literally hundreds of judgments that enabled us to resolve 40,000 images,

“Big parts of our brains are devoted to making sense of touch and our skin has billions of cells that process information about it,”

“The right type of friendly touch—like hugging your partner or linking arms with a dear friend—calms your stress response down. [Positive] touch activates a big bundle of nerves in your body that improves your immune system, regulates digestion and helps you sleep well. It also activates parts of your brain that help you empathize.”

Psychologist Sheldon Cohen and other researchers at Carnegie Mellon University cited hugging specifically as a form of touch that can strengthen the immune system in a 2014 study investigating whether receiving hugs—and more broadly, social support that gives the perception that one is cared for—could make people less susceptible to one of the viruses that causes the common cold.

Broadly speaking, the participants who had reported having more social support were less likely to get sick—and those who got more hugs were far more likely to report feeling socially supported.

Everybody should be open to people being a little more socially distant and not touching as much. Some of it will return and some of it won’t.”

Although there’s no exact substitute for human touch, if you’re struggling with this aspect of self-isolating in particular, there are a few alternatives that can offer similar health benefits for people who are social distancing

“When we’re touched [in a positive way], a cascade of events happens in the brain and one of the important ones is the release of a neurochemical called oxytocin,”

Keltner adds that dancing, singing or doing yoga with others via an online platform can also be highly effective substitutes for physical contact

“Not only would it be good to prevent coronavirus disease; it probably would decrease instances of influenza dramatically in this country,”

Zak says U.S. customs like shaking hands and hugging may be changed forever and suggests that non-tactile greetings like a nod, bow or wave may come to replace them. However, he says it will still be important to find ways to reintroduce the humanity of positive touch into in-person interactions without putting anyone’s physical or mental health in jeopardy.

“In-person interactions have a big effect on the brain releasing oxytocin, but interacting via video is actually not that [different],” he explains. “It’s maybe 80% as effective. Video conferencing is a great way to see and be seen.”

But for those who are quarantining alone or with people with whom they don’t have physical contact, loneliness and social isolation are growing health concerns.

this process reduces stress and improves immunity. “That’s super valuable in a time of pandemic.”

If you’re using a video chat service for work or school, Zak recommends that you take five minutes at the beginning of the call to focus on interpersonal connection.

to illustrate how dance parties like Daybreaker can be beneficial for people’s physical and mental health. “When you create a dance experience driven by music, community and participation, that’s how you’re able to release all four happy brain chemicals,” Agrawal says.

. In the 17th century, even Galileo writes about why, in a game with three dice, the number 10 should come up more than the number 9. It’s an observation that one would only be able to detect after thousands of rolls, but the reason behind it involves how many combinations of numbers can add up to each different option.

All these changes in dice come about, says Eerkens, “as different astronomers are coming up with new ideas about the world, and mathematicians are starting to understand numbers and probability.” Which came first: Did people begin to intuitively understand what true chance felt like, and adjusted dice accordingly, or did it trickle out from what would eventually become known as the scientific community?

And it does make you wonder: Would you know that fair dice should fall equally on each side, or that in a three-dice game, it’s better to bet on 10 than nine, if someone hadn’t told you?

The targets of xenophobia—derived from the Greek word for stranger—are no longer the Japanese. Instead, they are Muslim immigrants. Or Mexicans. Or the Chinese. Or whichever group we have come to fear.

The teacher, Jane Elliott, divided her class into two groups—those with blue eyes and those with brown or green eyes. The brown-eyed group received privileges and treats, while the blue-eyed students were denied rewards and told they were inferior. Within hours, the once-harmonious classroom became two camps, full of mutual fear and resentment. Yet, what is especially shocking is that the students were only in the third grade.

The drive to completely and quickly divide the world into "us" and "them" is so powerful that it must surely come from some deep-seated need.

Once the division is made, the inferences and projections begin to occur. For one, we tend to think more highly of people in the in-group than those in the out-group, a belief based only on group identity. Also, a person tends to feel that others in the in-group are similar to one's self in ways that—although stereotypical—may have little to do with the original criteria used to split the groups.

The differences in reaction time are small but telling. Again and again, researchers found that subjects readily tie in-group images with pleasant words and out-group images with unpleasant words. One study compares such groups as whites and blacks, Jews and Christians, and young people and old people. And researchers found that if you identify yourself in one group, it's easier to pair images of that group with pleasant words—and easier to pair the opposite group with unpleasant imagery. This reveals the underlying biases and enables us to study how quickly they can form.

If categorization and bias come so easily, are people doomed to xenophobia and racism? It's pretty clear that we are susceptible to prejudice and that there is an unconscious desire to divide the world into "us" and "them." Fortunately, however, research also shows that prejudices are fluid and that when we become conscious of our biases we can take active—and successful—steps to combat them

Unfortunately, such stereotypes are reinforced so often that they can become ingrained. It is difficult to escape conventional wisdom and treat all people as individuals, rather than members of a group. But that seems to be the best way to avoid the trap of dividing the world in two—and discriminating against one part of humanity.

“We know that kids seek validation via the Like button. We know that it can negatively affect kids’ and teenagers’ self-esteem,” said Jim Steyer, chief executive of the nonprofit Common Sense Media. “The public is finally waking up to how many of these tactics can be manipulative.”

Instagram, the photo-sharing site owned by Facebook, also began hiding some Likes and other metrics this year as part of an experiment intended to make users feel happier about the time they spend on the platform.

This could create “a less pressurized environment where people feel comfortable expressing themselves,” Mr. Mosseri said at the time.

The parents in these cases are often completely bewildered by the accusations. They often remember a totally different childhood home and accuse their children of rewriting what happened.

a more individualistic culture has meant that the function of family has changed. Once it was seen as a bond of mutual duty and obligation, and now it is often seen as a launchpad for personal fulfillment. There’s more permission to cut off people who seem toxic in your life.

There’s a lot of real emotional abuse out there, but as Coleman put it in an essay in The Atlantic, “My recent research — and my clinical work over the past four decades — has shown me that you can be a conscientious parent and your kid may still want nothing to do with you when they’re older.”

Either way, there’s a lot of agony for all concerned. The children feel they have to live with the legacy of an abusive childhood. The parents feel rejected by the person they love most in the world, their own child, and they are powerless to do anything about it. There’s anger, grief and depression on all sides — painful holidays and birthdays — plus, the next generation often grows up without knowing their grandparents.

there seems to be a generational shift in what constitutes abuse. Practices that seemed like normal parenting to one generation are conceptualized as abusive, overbearing and traumatizing to another.

Becca Bland, founder of the British support and advocacy group Stand Alone, told the BBC: “Now I can put my needs first rather than trying to fix things beyond my control. But, yes, I’m angry I didn’t get the mother I wanted.”

A 2012 survey from the Institute for Advanced Studies in Culture found that almost three-quarters of parents of school-age kids said they eventually want to become their children’s best friend.

Some kids seem to think they need to cut off their parents just to have their own life. “My mom is really needy and I just don’t need that in my life,

In other cases, children may be blaming their parents for the fact that they are not succeeding as they had hoped — it’s Mom and Dad who screwed me up.

it feels like a piece of what seems to be the psychological unraveling of America

Terrible trends are everywhere. Major depression rates among youths aged 12 to 17 rose by almost 63 percent between 2013 and 2016. American suicide rates increased by 33 percent between 1999 and 2019. The percentage of Americans who say they have no close friends has quadrupled since 1990,

Fifty-four percent of Americans report sometimes or always feeling that no one knows them well, according to a 2018 Ipsos survey.

political tribalism becomes a mechanism with which people can shore themselves up, vanquish shame, fight for righteousness and find a sense of belonging.

if we do not transform our pain, we will most assuredly transmit it.

As Tamara Plakins Thornton demonstrates in her book Handwriting in America, it has always been affected by changing social and cultural forces. In 18th-century America, writing was the domain of the privileged.

By law or custom, the enslaved were prohibited from literacy almost everywhere

The notion of a signature as a unique representation of a particular individual gradually came to be enshrined in the law and accepted as legitimate legal evidence.

Writing, though, was much less widespread—taught separately and sparingly in colonial America, most often to men of status and responsibility and to women of the upper classes. Men and women even learned different scripts—an ornamental hand for ladies, and an unadorned, more functional form for the male world of power and commerce.

increase in the number of women able to write. By 1860, more than 90 percent of the white population in America could both read and write.

Penmanship came to be seen as a marker and expression of the self—of gender and class, to be sure, but also of deeper elements of character and soul.

n New England, nearly all men and women could read; in the South, which had not developed an equivalent system of common schools, a far lower percentage of even the white population could do so

No, most of these history students admitted, they could not read manuscripts. If they were assigned a research paper, they sought subjects that relied only on published sources.

Didn’t professors make handwritten comments on their papers and exams? Many of the students found these illegible. Sometimes they would ask a teacher to decipher the comments; more often they just ignored them.

I wondered how many of my colleagues have been dutifully offering handwritten observations without any clue that they would never be read.

I asked the students if they made grocery lists, kept journals, or wrote thank-you or condolence letters. Almost all said yes. Almost all said they did so on laptops and phones or sometimes on paper in block letters

“There is something charming about receiving a handwritten note,” one student acknowledged. Did he mean charming like an antique curiosity? Charming in the sense of magical in its capacity to create physical connections between human minds? Charming as in establishing an aura of the original, the unique, and the authentic? Perhaps all of these

there are dangers in cursive’s loss. Students will miss the excitement and inspiration that I have seen them experience as they interact with the physical embodiment of thoughts and ideas voiced by a person long since silenced by death. Handwriting can make the past seem almost alive in the present.

All of us, not just students and scholars, will be affected by cursive’s loss. The inability to read handwriting deprives society of direct access to its own past. We will become reliant on a small group of trained translators and experts to report what history—including the documents and papers of our own families—was about.

The spread of literacy in the early modern West was driven by people’s desire to read God’s word for themselves, to be empowered by an experience of unmediated connection. The abandonment of cursive represents a curious reverse parallel: We are losing a connection, and thereby disempowering ourselves.
