are breeding a generation of the misinformed — a situation that has only grown more dire at a time when the president spreads falsehoods about public health and the election.

while false information flows unimpeded through Facebook groups, user posts and advertisements.

The company says it will limit political advertising in the week before Election Day — but with huge numbers of mail-in ballots already being sent in around the country, that will amount to too little, too late.

“I don’t think there is any question at this point voters will be more informed by seeking out news brands they trust rather than spending their time on social media where it’s less than clear,”

Twitter sometimes forces users to first click through a warning that a tweet violates its rules on election integrity,

The problem with such posts is that they are widely spread, echoed and believed — and that happens far more quickly than moderators can react with a warning label.

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,

Two of the most important factors, Peterson explained, are whether the memory “has emotion infused in it,” and whether the memory is coherent: Does the story our memory tells us actually hang together and make sense when we recall it later?

A professor at the University of North Carolina-Chapel Hill, Reznick explained that shortly after birth, infants can start forming impressions of faces and react when they see those faces again; this is recognition memory. The ability to understand words and learn language relies on working memory, which kicks in at around six months old. More sophisticated forms of memory develop in the child’s second year, as semantic memory allows children to retain understanding of concepts and general knowledge about the world.

I formed earlier memories using more rudimentary, pre-verbal means, and that made those memories unreachable as the acquisition of language reshaped how my mind works, as it does for everyone.

False memories do exist, but their construction appears to begin much later in life

A study by Peterson presented young children with fictitious events to see if they could be misled into remembering these non-existent events, yet the children almost universally avoided the bait. As for why older children and adults begin to fill in gaps in their memories with invented details, she pointed out that memory is a fundamentally constructive activity: We use it to build understanding of the world, and that sometimes requires more complete narratives than our memories can recall by themselves.

as people get older, it becomes easier to conflate actual memories with other stimuli.

He explained that recognition memory is our most pervasive system, and that associations with my hometown I formed as an infant could well have endured more than 20 years later, however vaguely.

give me enough time, and I’m sure that detail will be added to my memory. It’s just too perfect a story.

There might be desks, cushions, or benches arranged in rows or circles—however the teachers want them, as not every classroom will follow a template. Each classroom will be set up based on what is necessary to meet learning objectives. But schools will prioritize configuring classes to inspire learning first and foremost, and, where appropriate, reflect the diversity of environments that students are exposed to outside a school setting.

Students will have beautiful spaces that make them feel good to be at school—with art, living plants, music where appropriate, comfortable seating, and fast internet access.

Windows that open are a nice feature, as are clean bathrooms and individual desks that can be rearranged

Smaller schools and smaller rooms seem to work better than larger schools and larger rooms.  

My experience as a high-school principal taught me to never spend too much time worrying about the “small stuff.”

There will be a large open space that will serve as a community gathering spot. The classroom will have big windows to let a lot of natural light shine through. The room will be colorful without being obnoxious—colors will be blues, greens, whites, and yellows.

There will be areas where students can post ideas to help make the learning environment more engaging and fun. The classroom will also be tailored to the topic, but all will have interactive stations where hands-on learning can be experienced by all students.

In the future, we won’t have “classrooms.” The enemy of the future of the classroom has arguably been that phrase: “the future of the classroom.” It locks us into a model of believing students will be sorted by age and sit in a room together with one teacher in the front.

Form will follow function, and if one of the key principles of public education is to instill an appreciation for democracy, then classrooms will be arranged so that students are equals with one another

(not some in the front, others in the back), and so that students are active participants in learning, not passive recipients of teachers’ knowledge.

Whereas the traditional lecture hall connotes hierarchy, placing desks in a circle suggests students should be learning to debate and become decision makers. Within the circle, desks will also be clustered in small groups of four to encourage collaboration among students.

High-school classrooms will be designed by students themselves, providing breakout space for group work and more private areas for individual work and studying. High-school classrooms will reflect the transition that students are facing, allowing for independence but also providing a nurturing environment for curiosity.

It’s also important to look at the appropriate role of technology in the classroom. Technology can be a powerful tool, but it must be implemented with the intention of enhancing educator-facilitated learning, not replacing i

To his surprise, despite there being a mix of ethnicities and languages in Singapore’s multicultural army camps, the young officers managed to find common ground through military slang.

A false story is much more likely to go viral than a real story, the authors find. A false story reaches 1,500 people six times quicker, on average, than a true story does.

“In short, I don’t think there’s any reason to doubt the study’s results,” said Rebekah Tromble, a professor of political science at Leiden University in the Netherlands, in an email.

It’s a question that can have life-or-death consequences.“[Fake news] has become a white-hot political and, really, cultural topic, but the trigger for us was personal events that hit Boston five years ago,” said Deb Roy, a media scientist at MIT and one of the authors of the new study.

Ultimately, they found about 126,000 tweets, which, together, had been retweeted more than 4.5 million times. Some linked to “fake” stories hosted on other websites. Some started rumors themselves, either in the text of a tweet or in an attached image. (The team used a special program that could search for words contained within static tweet images.) And some contained true information or linked to it elsewhere.

Tweet A and Tweet B both have the same size audience, but Tweet B has more “depth,” to use Vosoughi’s term. It chained together retweets, going viral in a way that Tweet A never did. “It could reach 1,000 retweets, but it has a very different shape,” he said.Here’s the thing: Fake news dominates according to both metrics. It consistently reaches a larger audience, and it tunnels much deeper into social networks than real news does. The authors found that accurate news wasn’t able to chain together more than 10 retweets. Fake news could put together a retweet chain 19 links long—and do it 10 times as fast as accurate news put together its measly 10 retweets.

What does this look like in real life? Take two examples from the last presidential election. In August 2015, a rumor circulated on social media that Donald Trump had let a sick child use his plane to get urgent medical care. Snopes confirmed almost all of the tale as true. But according to the team’s estimates, only about 1,300 people shared or retweeted the story.

Why does falsehood do so well? The MIT team settled on two hypotheses.First, fake news seems to be more “novel” than real news. Falsehoods are often notably different from the all the tweets that have appeared in a user’s timeline 60 days prior to their retweeting them, the team found.Second, fake news evokes much more emotion than the average tweet. The researchers created a database of the words that Twitter users used to reply to the 126,000 contested tweets, then analyzed it with a state-of-the-art sentiment-analysis tool. Fake tweets tended to elicit words associated with surprise and disgust, while accurate tweets summoned words associated with sadness and trust, they found.

It suggests—to me, at least, a Twitter user since 2007, and someone who got his start in journalism because of the social network—that social-media platforms do not encourage the kind of behavior that anchors a democratic government. On platforms where every user is at once a reader, a writer, and a publisher, falsehoods are too seductive not to succeed: The thrill of novelty is too alluring, the titillation of disgust too difficult to transcend. After a long and aggravating day, even the most staid user might find themselves lunging for the politically advantageous rumor. Amid an anxious election season, even the most public-minded user might subvert their higher interest to win an argument.

On Tuesday, the Russian leader paid a visit to the main Moscow hospital for monitoring suspected coronavirus patients, donning protective gear to visit the hospital in the city's suburb of Kommunarka. It was the kind of costume play we're used to seeing from the Kremlin, and reminiscent of one of his earliest moves as Russia's acting president: flying to the war-torn republic of Chechnya in 2000 in the co-pilot's seat of an Su-27 fighter jet.

Because tone comes from the top, you see the President's surrogates and even Cabinet officials echo it. But sometimes they go too far and give away the game. Case in point, Secretary of State Mike Pompeo on "Face The Nation":

"If there was election interference that took place by the Vice President, I think the American people deserve to know."

An analysis by The Washington Post's Philip Bump found that his top five insults were "fake," "failed," "dishonest," "weak" and "liar."

In fact, studies demonstrate bias across nearly every field and for nearly every group of people. If you’re Latino, you’ll get less pain medication than a white patient. If you’re an elderly woman, you’ll receive fewer life-saving interventions than an elderly man. If you are a man being evaluated for a job as a lab manager, you will be given more mentorship, judged as more capable, and offered a higher starting salary than if you were a woman. If you are an obese child, your teacher is more likely to assume you’re less intelligent than if you were slim. If you are a black student, you are more likely to be punished than a white student behaving the same way.

Mike Pence, for instance, bristled during the 2016 vice-presidential debate: “Enough of this seeking every opportunity to demean law enforcement broadly by making the accusation of implicit bias whenever tragedy occurs.” And two days after the first presidential debate, in which Hillary Clinton proclaimed the need to address implicit bias, Donald Trump asserted that she was “essentially suggesting that everyone, including our police, are basically racist and prejudiced.”

Still other people, particularly those who have been the victims of police violence, also reject implicit bias—on the grounds that there’s nothing implicit about it at all.

Bias is woven through culture like a silver cord woven through cloth. In some lights, it’s brightly visible. In others, it’s hard to distinguish. And your position relative to that glinting thread determines whether you see it at all.

All of which is to say that while bias in the world is plainly evident, the exact sequence of mental events that cause it is still a roiling question.  Devine, for her part, told me that she is no longer comfortable even calling this phenomenon “implicit bias.” Instead, she prefers “unintentional bias.” The term implicit bias, she said, “has become so broad that it almost has no meaning.”

Weeks afterwards, students who had participated noticed bias more in others than did students who hadn’t participated, and they were more likely to label the bias they perceived as wrong. Notably, the impact seemed to last: Two years later, students who took part in a public forum on race were more likely to speak out against bias if they had participated in the training.

This hierarchy matters, because the more central a layer is to self-concept, the more resistant it is to change. It’s hard, for instance, to alter whether or not a person values the environment. But if you do manage to shift one of these central layers, Forscher explained, the effect is far-reaching.

And if there’s one thing the Madison workshops do truly shift, it is people’s concern that discrimination is a widespread and serious problem. As people become more concerned, the data show, their awareness of bias in the world grows, too.

An intriguing thesis is that possessing a strong sense of life purpose provides us with that latent power to persevere and take action, even in the face of daunting odds and potential adversity. This is related to, though not identical to, the concept of resilience: the ability to bounce back from losses, failures, and disappointments

The Pentagon said the focus of its own response was to explore “potential ways to look at mitigating future attacks”.
