In people it is called episodic memory, and it involves a sense of self. In animals, it’s called episodic-like memory, because it’s difficult to try to plumb something as elusive as self without the aid of language.

Dr. Fugazza and colleagues reported online in Current Biology that this showed that the dogs remembered an event they hadn’t been concentrating on, the trainer’s action. She said one aspect strengthened that conclusion: The dogs tended to lie down immediately when they got back to the mat, suggesting that their heads were in “lie down” mode, not “do it” mode.

He said human episodic memory is lost in Alzheimer’s disease and he and others study animal memory in hopes of learning how to combat that loss. The work on dogs offers a new technique that could be very useful, he said.

More 5inShare Email Print A defendant in the Atlanta Public Schools case turns herself in at the Fulton County Jail on April 2. (David Goldman/AP) Earlier this week at The Atlantic, Emily Richmond asked whether high-stakes testing caused the Atlanta schools cheating scandal. The answer, I would argue, is yes... just not in the way you might think. Tests don't cause unethical behavior. But they did cause the Atlanta cheating scandal, and they are doing damage to the teaching profession. The argument that tests do not cause unethical behavior is fairly straightforward, and has been articulated by a number of writers. Jonathan Chait quite correctly points out that unethical behavior occurs in virtually all professions -- and that it occurs particularly when there are clear incentives to succeed. Incentivizing any field increases the impetus to cheat. Suppose journalism worked the way teaching traditionally had. You get hired at a newspaper, and your advancement and pay are dictated almost entirely by your years on the job, with almost no chance of either becoming a star or of getting fired for incompetence. Then imagine journalists changed that and instituted the current system, where you can get really successful if your bosses like you or be fired if they don't. You could look around and see scandal after scandal -- phone hacking! Jayson Blair! NBC's exploding truck! Janet Cooke! Stephen Glass! -- that could plausibly be attributed to this frightening new world in which journalists had an incentive to cheat in order to get ahead. It holds true of any field. If Major League Baseball instituted tenure, and maybe used tee-ball rules where you can't keep score and everybody gets a chance to hit, it could stamp out steroid use. Students have been cheating on tests forever -- massive, systematic cheating, you could say. Why? Because they have an incentive to do well. Give teachers and administrators an incentive for their students to do well, and more of them will cheat. For Chait, then, teaching has just been made more like journalism or baseball; it has gone from an incentiveless occupation to one with incentives.

Chait refers to violations of journalistic ethics -- like the phone-hacking scandal -- and suggests they are analogous to Major-League steroid use, and that both are similar to teachers (or students) cheating on tests. But is phone hacking "cheating"

Phone hacking was, then, not an example of cheating. It was a violation of professional ethics. And those ethics are not arbitrarily imposed, but are intrinsic to the practice of journalism as a profession committed to public service and to truth.

Creating and disseminating convincing propaganda used to require the resources of a state. Now all it takes is a smartphone.

Generative artificial intelligence is now capable of creating fake pictures, clones of our voices, and even videos depicting and distorting world events. The result: From our personal circles to the political circuses, everyone must now question whether what they see and hear is true.

exposure to AI-generated fakes can make us question the authenticity of everything we see. Real images and real recordings can be dismissed as fake. 

mainstream platforms learned their lesson, accepting that they should intervene aggressively in more and more cases when users post content that might cause social harm.

During the wildfires in the American West in September, Facebook and Twitter took down false claims about their cause, even though the platforms had not done the same when large parts of Australia were engulfed in flames at the start of the year

Twitter, Facebook, and YouTube cracked down on QAnon, a sprawling, incoherent, and constantly evolving conspiracy theory, even though its borders are hard to delineate.

For much of 2020, doctors and public-health officials thought the virus was transmitted through droplets emitted from one person’s mouth and touched or inhaled by another person nearby. We were advised to stay at least 6 feet away from each other to avoid the droplets

A small cadre of aerosol scientists had a different theory. They suspected that Covid-19 was transmitted not so much by droplets but by smaller infectious aerosol particles that could travel on air currents way farther than 6 feet and linger in the air for hours. Some of the aerosol particles, they believed, were small enough to penetrate the cloth masks widely used at the time.

The group had a hard time getting public-health officials to embrace their theory. For one thing, many of them were engineers, not doctors.

As a neurosurgeon, I did not believe in the phenomenon of near-death experiences. I grew up in a scientific world, the son of a neurosurgeon. I followed my father’s path and became an academic neurosurgeon, teaching at Harvard Medical School and other universities. I understand what happens to the brain when people are near death, and I had always believed there were good scientific explanations for the heavenly out-of-body journeys described by those who narrowly escaped death.

In the fall of 2008, however, after seven days in a coma during which the human part of my brain, the neocortex, was inactivated, I experienced something so profound that it gave me a scientific reason to believe in consciousness after death.

All the chief arguments against near-death experiences suggest that these experiences are the results of minimal, transient, or partial malfunctioning of the cortex. My near-death experience, however, took place not while my cortex was malfunctioning, but while it was simply off. This is clear from the severity and duration of my meningitis, and from the global cortical involvement documented by CT scans and neurological examinations. According to current medical understanding of the brain and mind, there is absolutely no way that I could have experienced even a dim and limited consciousness during my time in the coma, much less the hyper-vivid and completely coherent odyssey I underwent.

Were people happier in the 1950s than they are today? Or were they more frustrated, repressed and sad? To find out, you'd have to compare the emotions of one generation to another. British anthropologists think they may have found the answer — embedded in literature.

This effort began simply with lists of "emotion" words: 146 different words that connote anger; 92 words for fear; 224 for joy; 115 for sadness; 30 for disgust; and 41 words for surprise. All were from standardized word lists used in linguistic research.

We didn't really expect to find anything," he says. "We were just curious. We really expected the use of emotion words to be constant through time." Instead, in the study they published in the journal PLOS ONE, the anthropologists found very distinct peaks and valleys, Bently says.

I often joke that every cable news show should be forced to display a disclaimer, streaming in a loop at the bottom of the screen. The disclaimer would read: “These talking heads have been scientifically proven to not know what they are talking about. Their blather is for entertainment purposes only.” The viewer would then be referred to Tetlock’s most famous research project, which began in 1984.

He picked a few hundred political experts – people who made their living “commenting or offering advice on political and economic trends” – and began asking them to make predictions about future events. He had a long list of pertinent questions. Would George Bush be re-elected? Would there be a peaceful end to apartheid in South Africa? Would Quebec secede from Canada? Would the dot-com bubble burst? In each case, the pundits were asked to rate the probability of several possible outcomes. Tetlock then interrogated the pundits about their thought process, so that he could better understand how they made up their minds.

Most of Tetlock’s questions had three possible answers; the pundits, on average, selected the right answer less than 33 percent of the time. In other words, a dart-throwing chimp would have beaten the vast majority of professionals. These results are summarized in his excellent Expert Political Judgment.

what psychology teaches us. Turns out most of us just aren’t that good at calculating risk, especially when it comes to huge natural events like earthquakes. That also means we’re not very good at mitigating those kinds of risks. Why? And is it possible to get around our short-sightedness, so that this time, we’re actually prepared? Risk perception is a vast, complex field of research. Here are just some of the core findings.

Studies show that when people calculate risk, especially when the stakes are high, we rely much more on feeling than fact. And we have trouble connecting emotionally to something scary if the odds of it happening today or tomorrow aren’t particularly high. So, if an earthquake, flood, tornado or hurricane isn’t immediately imminent, people are unlikely to act. “Perceiving risk is all about how scary or not do the facts feel,”

This feeling also relates to how we perceive natural, as opposed to human-made, threats. We tend to be more tolerant of nature than of other people who would knowingly impose risks upon us—terrorists being the clearest example. “We think that nature is out of our control—it’s not malicious, it’s not profiting from us, we just have to bear with it,”

Among economists more generally, a lot of the criticism seems to amount to the view that macroeconomics is bunk, and that we should stick to microeconomics, which is the real, solid stuff. As I’ll explain in a moment, that’s all wrong

in an important sense the past decade has been a huge validation for textbook macroeconomics; meanwhile, the exaltation of micro as the only “real” economics both gives microeconomics too much credit and is largely responsible for the ways macroeconomic theory has gone wrong.

Finally, many outsiders and some insiders have concluded from the crisis that economic theory in general is bunk, that we should take guidance from people immersed in the real world – say, business leaders — and/or concentrate on empirical results and skip the models

Emoji are now used in around half of every sentence on sites like Instagram, and Facebook looks set to introduce them alongside the famous “like” button as a way of expression your reaction to a post.

If you were to believe the headlines, this is just the tipping point: some outlets have claimed that emoji are an emerging language that could soon compete with English in global usage. To many, this would be an exciting evolution of the way we communicate; to others, it is linguistic Armageddon.

Do emoji show the same characteristics of other communicative systems and actual languages? And what do they help us to express that words alone can’t say?When emoji appear with text, they often supplement or enhance the writing. This is similar to gestures that appear along with speech. Over the past three decades, research has shown that our hands provide important information that often transcends and clarifies the message in speech. Emoji serve this function too – for instance, adding a kissy or winking face can disambiguate whether a statement is flirtatiously teasing or just plain mean.

The implication of Hannah-Jones’s tweet and candidate Biden’s quip seems to be that you can have African ancestry, dark skin, textured hair, and perhaps even some “culturally black” traits regarding tastes in food, music, and ways of moving through the world. But unless you hold the “correct” political beliefs and values, you are not authentically black.

In a now-deleted tweet from May 22, 2020, Nikole Hannah-Jones, a Pulitzer Prize-winning reporter for The New York Times, opined, “There is a difference between being politically black and being racially black.”

Shelly Eversley’s The Real Negro suggests that in the latter half of the 20th century, the criteria of what constitutes “authentic” black experience moved from perceptible outward signs, like the fact of being restricted to segregated public spaces and speaking in a “black” dialect, to psychological, interior signs. In this new understanding, Eversley writes, “the ‘truth’ about race is felt, not performed, not seen.”

But an appeals court granted a stay of execution Tuesday, shortly after another appeals court lifted an Indiana judge’s ruling that found she was likely mentally ill and couldn’t comprehend she would be put to death.

“I don’t believe she has any rational comprehension of what’s going on at all,” Henry said.

Americans who rely the most on social media to get their news are also far less likely to have accurate or complete knowledge of political events

A huge 9th-century stone monument in Sweden may have been erected by Vikings who feared a repeat of a cold climate crisis that took place more than 300 years earlier, according to a new study.

A new interdisciplinary study by scholars from Swedish universities has concluded that the inscription is about anxiety triggered by a son's death and fears of a new cold climate crisis.

The study was based on archaeological research on a cold climate catastrophe from the years 536 to 550, which affected Scandinavia. The crisis took hold after a series of volcanic events and led to lower average temperatures, crop failures, hunger and mass extinctions. It is also estimated that the population of the Scandinavian Peninsula fell by 50% or more.

A team of scientists hunting dark matter has recorded suspicious pings coming from a vat of liquid xenon underneath a mountain in Italy

If the signal is real and persists, the scientists say, it may be evidence of a species of subatomic particles called axions — long theorized to play a crucial role in keeping nature symmetrical but never seen — streaming from the sun.

Instead of axions, the scientists may have detected a new, unexpected property of the slippery ghostly particles called neutrinos. Yet another equally likely explanation is that their detector has been contaminated by vanishingly tiny amounts of tritium, a rare radioactive form of hydrogen.

“It was really moving to Texas that set me on this path of figuring out how to communicate about climate change,” she told me. “I was the only climate scientist within two hundred miles.”

She records the questions she is asked afterward, using an app, and the two most frequent are: “What gives you hope?” and “How do I talk to my [blank] about climate change?

In the late nineties, a Gallup poll found that forty-six per cent of Democrats and forty-seven per cent of Republicans agreed that the effects of global warming had already begun.

IMAGINE a future in which humanity’s accumulated wisdom about Earth — our vast experience with weather trends, fish spawning and migration patterns, plant pollination and much more — turns increasingly obsolete. As each decade passes, knowledge of Earth’s past becomes progressively less effective as a guide to the future. Civilization enters a dark age in its practical understanding of our planet.

as Earth warms, our historical understanding will turn obsolete faster than we can replace it with new knowledge. Some patterns will change significantly; others will be largely unaffected, though it will be difficult to say what will change, by how much, and when.

Until then, farmers will struggle to reliably predict new seasonal patterns and regularly plant the wrong crops. Early signs of major drought will go unrecognized, so costly irrigation will be built in the wrong places. Disruptive societal impacts will be widespread.

the much more tenable and dangerous proposition that freedom is undesirable and that intellectual honesty is a form of antisocial selfishness

the controversy over freedom of speech and of the press is at bottom a controversy over the desirability, or otherwise, of telling lies.

What is really at issue is the right to report contemporary events truthfully, or as truthfully as is consistent with the ignorance, bias, and self-deception from which every observer necessarily suffers
