“Subjecting 5-year-olds to this technology will not make anyone safer, and we can’t allow invasive surveillance to become the norm in our public spaces,” said Stefanie Coyle, deputy director of the Education Policy Center for the New York Civil Liberties Union.

When the system is on, Mr. LiPuma said, the software looks at the faces captured by the hundreds of cameras and calculates whether those faces match a “persons of interest” list made by school administrators.

Jayde McDonald, a political science major at Buffalo State College, grew up as one of the few black students in Lockport public schools. She said she thought it was too risky for the school to install a facial recognition system that could automatically call the police.

“I’m not sure where they are in the school or even think I’ve seen them,” said Brooke Cox, 14, a freshman at Lockport High School. “I don’t fully know why we have the cameras. I haven’t been told what their purpose is.”

“If suspended students are put on the watch list, they are going to be scrutinized more heavily,” he said, which could lead to a higher likelihood that they could enter into the criminal justice system.

Days after the district announced that the technology had been turned on, some students said they had been told very little about how it worked.

“We all want to keep our children safe in school,” she said. “But there are more effective, proven ways to do so that are less costly.”

For their study, they analyzed knowledge held by 57 indigenous communities in the Amazon basin, the Andes and the Chocó region to collate their knowledge of palm trees. The researchers then depicted the different palm species and their uses in graphical form in a network, from which they could identify the local and regional links between the knowledge of indigenous communities.

"In this context, cultural diversity is just as important as biological diversity," says Jordi Bascompte. "In particular, the simultaneous loss of plant species and cultural inheritance leads to a much faster disintegration of the indigenous knowledge network."

However, the irreplaceable knowledge that is gradually disappearing from indigenous communities is equally important for the service that an ecosystem provides."

The study also highlights the value of transdisciplinary collaboration between ecology and social science: "The relationship established between biological and cultural diversity can help strengthen the resilience of indigenous communities in the face of global change."

"We assume that individual units of knowledge are dispersed throughout the entire brain in the form of pieces of information," explains Erhan Genç. "Efficient networking of the brain is essential in order to put together the information stored in various areas of the brain and successfully recall knowledge content."

To answer the question of which constants occur in Einstein's theory of relativity, you have to connect the meaning of the term "constant" with knowledge of the theory of relativity. "We assume that more efficient networking of the brain contributes to better integration of pieces of information and thus leads to better results in a general knowledge test,

There is much to be said, however, for art’s ability to evoke emotion based on common experience, sincerity, talent, and unique skill. Rich proves that AI can be used to answer complicated questions. But what we think of as creative work in the humanities is much more often about asking questions than it is about answering them.

It’s well-known that most of the emails are composed by nonnative speakers of English, as is clear from the many grammatical and punctuation mistakes, broken syntax, missing words, and malapropisms (“the will to personify the façade to its practical conclusion” for “pursue the charade”). With so many mistakes, how can this language really fool anyone? Often, victims know the message comes from a nonnative speaker, or they may be nonnative English speakers themselves and may not always recognize grammatical errors.

The scammers make extraordinary efforts to use technical, military, financial or otherwise professional language in a clumsy caricature of what formal, educated English sounds like (“government officials . . . awarded themselves contracts that were grossly over-invoiced in various ministries and parastatals”) to keep up the pretence of being a barrister, a brigadier-general, or a bank official.

It’s a simple scam, but appears to be effective when it reaches credulous types who are willing to ignore the warning signs in search of a treasure hunting adventure that can make a life extraordinary for a while, before it all ends in grief.

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.

‘Where are you, Sue?’ I was brought up short. I tried to picture my own body and where it really was, but my prefrontal cortex was deactivated as the brain hovered on the edge of sleep (Muzur et al 2002). With my TPJ disturbed it was impossible to combine a body schema with vestibular and sensory input to give a firm sense of an embodied self (Blanke et al 2002).

The roofs, gutters and chimneys I saw were just as I imagined them, not as they were. So were the cities, lakes, oceans and islands I saw. I laughed at the vivid ‘star-shaped island with a hundred trees’, believing it was a thought-form in the astral plane (Besent 1896, Findlay 1931) because that was the only theory I knew.

I was too tired to do more than glimpse this new vastness. In exhaustion, I seemed to face a choice, to stay in this marvelous, right-seeming, perfect state, or return to ordinary life. The choice made itself and the struggle began. After more than two hours of serious disturbance, this brain took some time to reinstate both body schema and self-image and even then confused my own body with others. When I opened my eyes I felt and saw greyish body-shapes around the others as well as myself; displaced body schemas that gradually faded until I was (more or less) back to normal. Yet nothing was ever quite the same again.”

But that’s the joy of doing science at all. I have not, in these posts, covered the tunnel experience, the silver cord and several other features more commonly found during near-death experiences, but I may return to them in future. For now I hope you have enjoyed this series of OBE stories.

When I consider the near-decade I have spent on social media, this worry makes sense. As with many in my generation, Twitter was my entry into conversations happening on a global scale; long before my byline graced any publication, tweeting was how I felt a part of the world.

was measuring my individual worth in constant visibility. Implicit in my follower’s question “Where will you go?” is the resounding question “How will we know where you’ve gone?” Privacy is considered a small exchange for the security of being well known and well liked.

Perhaps at the root of this anxiety over being forgotten is an urgent question of how one ought to form a legacy; with the rise of automation, a widening wealth gap and an unstable political climate, it is easy to feel unimportant. It is almost as if the world is too big and we are much too small to excel in it in any meaningful way.

“The secret of a full life is to live and relate to others as if they might not be there tomorrow, as if you might not be there tomorrow,” the writer Anaïs Nin said. “This feeling has become a rarity, and rarer every day now that we have reached a hastier and more superficial rhythm, now that we believe we are in touch with a greater amount of people. This is the illusion which might cheat us of being in touch deeply with the one breathing next to us.”

“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.

If the disagreement persists, speak your truth even when it’s hard. Speak your truth without fear of judgment or retribution. Respond from the heart first and the head second. Remain calm and try to be respectful of the other person, even if you deeply disagree with his or her position. Keeping an open mind may help you to find a peaceful resolution.

Lastly, be thankful for the experience. Even when an argument is uncomfortable, it can help us grow and learn about ourselves.

When scientists ask: “How old do you feel, most of the time?” the answer tends to reflect the state of people’s physical and mental health. “This simple question seems to be particularly powerful,” says Antonio Terracciano, a professor of geriatrics at Florida State University College of Medicine in Tallahassee.Sign up for the Well NewsletterGet the best of Well, with the latest on health, fitness and nutrition.Sign Up* Captcha is incomplete.

Scientists are finding that people who feel younger than their chronological age are typically healthier and more psychologically resilient than those who feel older. They perform better on memory tasks and are at lower risk of cognitive decline.

If you’re over 40, chances are you feel younger than your driver’s license suggests. Some 80 percent of people do, according to Dr. Stephan. A small fraction of people — fewer than 10 percent — feel older.

At age 50, people may feel about five years, or 10 percent, younger, but by the time they’re 70 they may feel 15 percent or even 20 percent younger.

In a 2018 German study, investigators asked people in their 60s, 70s and early 80s how old they felt, then measured their walking speed in two settings. Participants walked 20 feet in the laboratory while being observed and timed. They also wore belts containing an accelerometer while out and about in their daily lives. Those who reported feeling younger tended to walk faster during the lab assessment. But feeling younger had no impact on their walking speed in real life.

Indeed, in cultures where elders are respected for their wisdom and experience, people don’t even understand the concept of subjective age, he said. When a graduate student of Dr. Weiss’s did research in Jordan, the people he spoke with “would say, ‘I’m 80. I don’t know what you mean by ‘How old do I feel?’”

As we age, we tend to become generally happier and more satisfied, said Dr. Tracey Gendron, a gerontologist at Virginia Commonwealth University who questions the whole notion of subjective age research

“Older age is a time that we can actually look forward to. People really just enjoy themselves more and are at peace with who they are. I would love for everyone to say their age at every year and celebrate it.”

Humility is a relative newcomer to social and personality psychology, at least as a trait or behavior to be studied on its own. It arrived as part of the effort, beginning in the 1990s, to build a “positive” psychology: a more complete understanding of sustaining qualities such as pride, forgiveness, grit and contentment.

In another, ongoing study, Dr. Krumrei Mancuso had 587 American adults complete questionnaires intended to measure levels of intellectual humility. The participants rated how much they agreed with various statements, including “I feel small when others disagree with me on topics that are close to my heart,” and “For the most part, others have more to learn from me than I have to learn from them.” Those who scored highly on humility — not that they’d boast about it — also scored lower on measures of political and ideological polarization, whether conservative or liberal.

“These kinds of findings may account for the fact that people high in intellectual humility are not easily manipulated with regard to their views,” Dr. Krumrei Mancuso said. The findings, she added, may also “help us understand how humility can be associated with holding convictions.”

Now that humility is attracting some research attention, Dr. Van Tongeren said, there are a number of open questions, including whether it can somehow be taught, or perhaps integrated into psychotherapy. “One of the thorny issues is that the people who are the most open and willing cultivate humility might be the ones who need it the least,” he said. “And vice versa: Those most in need could be the most resistant.”

Between 10 and 15 percent of adults score highly on measures of humility, depending on the rating scale used. That’s at least 25 million humble people in this country alone.

The advantage of having many different waves of data from the same people is that it enables researchers to speculate on whether changes in one characteristic cause changes in another. This can be done by asking whether changes at one time in one factor predict another more strongly than the reverse

irst, as we might expect, people’s personality characteristics and values are fairly stable. People’s responses to both the personality inventory and the values scale did not change much over time. However, the responses to the personality inventory changed less than the responses to the values survey.

Overall, some personality characteristics and some values are related. Agreeableness was correlated with the value of being prosocial (that is, wanting to engage in positive actions for society). Conscientiousness was correlated with conformity (which reflects that conscientious people tend to want to follow rules including societal rules). Extraversion was related to the value of enjoyment. Openness correlated with the value of self-direction. There were no strong correlations between neuroticism and any of the values.

In addition, personality traits appeared to influence a variety of measures of well-being. People high in agreeableness, conscientiousness, extraversion, and openness tended to show higher measures of well-being while being high in neuroticism was linked to decreased measures of well-being.

First, in an era in which key findings fail to replicate, this study solidifies the relationship between personality characteristics and values that have been observed before. It also demonstrates that both personality characteristics and values change slowly.

Second, this work suggests that changes in personality characteristics (which reflect people’s underlying motivation) have a bigger impact on values than changes in values have on people’s personality characteristics.

Third, this work suggests that both personality characteristics and values are related to people’s sense of well-being. However, personality characteristics seem to have a broad impact. Changes in personality can precede changes in well-being, but it appears that changes in well-being may actually have an impact on people’s values.

This research suggests that you should probably give yourself the benefit of the doubt when you meet other people. Even if you feel like you had a bad conversation with them, chances are you made a favorable impression. Other people probably like you better than you think they do.

That also means that if you’re interested in meeting up with someone again, you should reach out. You might be pleasantly surprised to find out that the other person would like to hang out with you as well.

The research is clear that sleep is critical for healthy functioning and development at all points across the lifespan. Sleep disturbances have been linked to a host of outcomes including more difficulty concentrating and learning new material, lower academic performance, higher rates of obesity, increased inflammation, higher mortality, and compromised psychological health.

researchers found that students slept an average of 34 minutes more after the start time delay. Moreover, the increase in sleep duration was explained by students waking up later (that is, students were still going to bed around the same time). In addition, delaying school start times was also associated with higher grades, lower levels of daytime sleepiness, and fewer first-period tardies and absences. 

With California schools leading the way in implementing a delay at the state level, in the next three years, it is my hope that we will have more information and data about all the ways in which school start times impact all levels of a school system (e.g., bus drivers, teachers, students, parents, families, administrators) and for all students.  

In a second session, he showed them an entirely new set of words and asked which words were familiar from the earlier, bogus session. Subjects were more likely to think they'd seen positive words—such as "charm" and "glory"—than either negative or neutral words that appear with the same frequency in English.

“It’s almost like people will say to you, ‘I want a strategy,’ and what they really mean is, ‘I want someone to understand,’” said Heather Havrilesky, an advice columnist and author of “What if This Were Enough?”

Be clear on the advice-seeker’s goals. When people approach Austin Kleon, author of “Steal Like an Artist,” for advice, he drills down and identifies the exact problem: “What do you want to know specifically that I can help you with?” This way, he won’t overwhelm the person with irrelevant information.

Consider your qualifications. People often go to those close to them for advice, even if family members and friends aren’t always in the best position to effectively assist, Dr. Tost said. Ask yourself: “Do I have the expertise, experience or knowledge needed to provide helpful advice in this situation?” If you do, fantastic! Advise away. If you don’t, rather than give potentially unhelpful advice, identify someone who is in a better position to help.

Words have power. Words can heal. A recent study found that doctors who simply offer assurance can help alleviate their patients’ symptoms. It’s essential to start the advice-giving conversation with this same reassuring tone.

People tend to resist when advice is preachy, Ms. Marshall said. Saying, “I’ve been there and here’s what I did,” makes people more receptive

Look for physical signs of relief. Examine facial cues and body language: eyes and mouth softening, shoulders lowering or letting breath out, for example. Those are good indicators your advice is resonating.

Identify takeaways (and give an out). It’s not realistic for people to act on every piece of advice you give. After discussing a problem and suggesting how to handle it, Ms. Marshall asks her clients what tidbit resonated with them the most.

“Your mileage may vary. Take what you need and leave the rest.”

Agree on next steps. Lastly, ask what kind of continued support is needed (if any) and what efforts should be avoided.

Did Federalists just use the specter of the Illuminati to tar their rivals? Or did they mean it? Did the Jeffersonians really think the Federalists were conspiring to bring back monarchy as they alleged? Or were they just trying to win elections? The answer depends on who and when, but it’s safe to say that some did believe these theories.

Conspiracy theory after theory, Americans cast a paranoid eye on their partisan opponents throughout the 19th and 20th centuries. According to the Oxford English Dictionary, the phrase “conspiracy theory” first appeared in the early 20th century United States, in the context of political histories of the 19th century.

Democrats’ anxieties about Russian conspiracies to interfere in the 2016 campaign cannot be extricated from this historical context of paranoia just because they have a significant basis in fact. As Joseph Heller wrote, “Just because you’re paranoid doesn’t mean they’re not after you.”

The republican political theory underlying the American paranoid style had its origin in the writings of opposition politicians in 18th-century Britain. Since then, conspiratorial thinking, has remained most attractive to opposition parties seeking to discredit their establishment rivals. This is the nature of Trump’s criticism of Democratic investigations of Russian conspiracies to hack the 2016 campaign. They’re just whining because they lost, Trump has said repeatedly.

If Trump’s embrace of the Ukraine conspiracy doesn’t sink his political future by leading to impeachment, it may nonetheless signal that his political future is bleak.

We know that rumination (dwelling on personal problems) and social isolation are common features of depression. However, we don’t know whether these findings reflect differences in attention or thinking style. Does depression cause people to focus on themselves, or do people who focus on themselves get symptoms of depression?

Our lab recently conducted a big data text analysis of 64 different online mental health forums, examining over 6,400 members. “Absolutist words” – which convey absolute magnitudes or probabilities, such as “always”, “nothing” or “completely” – were found to be better markers for mental health forums than either pronouns or negative emotion words.

From the outset, we predicted that those with depression will have a more black and white view of the world, and that this would manifest in their style of language.

Crucially, those who have previously had depressive symptoms are more likely to have them again. Therefore, their greater tendency for absolutist thinking, even when there are currently no symptoms of depression, is a sign that it may play a role in causing depressive episodes. The same effect is seen in use of pronouns, but not for negative emotion words.

But as the World Health Organisation estimates that more than 300m people worldwide are now living with depression, an increase of more than 18% since 2005, having more tools available to spot the condition is certainly important to improve health and prevent tragic suicides such as those of Plath and Cobain.

“When queried about their responses, the European Americans seemed to experience a threat to their independent self,” the authors write. “Many felt that something—their right to express their personal preference—had been taken from them.”

These cultural differences also separated Americans of different class backgrounds. In a version of the “free pen” experiment, Americans with only a high school education were much less attached to making choices than their college-educated counterparts. Similarly, when asked how they would feel if a friend bought the same car they had, college-educated Americans reacted negatively. In contrast, a representative response from one working-class participant was, “Cool. Let’s start a car club!”

Meanwhile, close relationships—which inevitably come with responsibilities and restraints on free choice—may be the most significant predictor of wellbeing.
