What makes it so hard to quit?

two culprits: aspartame and caffeine. Or, to be more precise: addiction to sweetness and to caffeine. Individually, they’re bad; together, they’re an addict’s nightmare.

A 12-ounce can of regular Coke has 34 milligrams of caffeine, whereas Diet Coke has 11 milligrams more, according to Coca-Cola. (An 8-ounce cup of coffee has about 95 mg.) Artificial sweeteners activate the brain’s reward system, but only about half as much as regular sugar, said Dr. Peeke. Faux sugar doesn’t pack the same wallop as the real stuff, so it keeps you wanting more and more.

“Reminiscence” is a great illustration of how strangely passive and defeatist an industry full of Prius early adopters has been about the biggest challenge of our time.

Hollywood’s reliance on big-budget action movies plays a role in its inability to address climate change effectively. In an industry reliant on chases, special effects and disasters, even ostensible “issue movies” get wedged into the same template.

these movies share at least one thing: pessimism. Climate change will be catastrophic — as will be many human responses to it.

At least 27 percent of Americans are estranged from a member of their own family, and research suggests about 40 percent of Americans have experienced estrangement at some point.

The most common form of estrangement is between adult children and one or both parents — a cut usually initiated by the child. A study published in 2010 found that parents in the U.S. are about twice as likely to be in a contentious relationship with their adult children as parents in Israel, Germany, England and Spain.

the children in these cases often cite harsh parenting, parental favoritism, divorce and poor and increasingly hostile communication often culminating in a volcanic event

Plato and Aristotle disagreed about the imagination

Plato gave the impression that imagination is a somewhat airy-fairy luxury good. It deals with illusions and make-believe and distracts us from reality and our capacity to coolly reason about it. Aristotle countered that imagination is one of the foundations of all knowledge.

What is imagination?

To test Darwin’s theory, the researchers quizzed people on several topics, such as grammar, logical reasoning and humor. After each test, they asked the participants how they thought they did. Specifically, participants were asked how many of the other quiz-takers they beat.

Dunning was shocked by the results, even though it confirmed his hypothesis. Time after time, no matter the subject, the people who did poorly on the tests ranked their competence much higher. On average, test takers who scored as low as the 10th percentile ranked themselves near the 70th percentile. Those least likely to know what they were talking about believed they knew as much as the experts.

Dunning and Kruger’s results have been replicated in at least a dozen different domains: math skills, wine tasting, chess, medical knowledge among surgeons and firearm safety among hunters.

a recent working paper by Nico Voigtländer and Sebastian Ottinger of the University of California at Los Angeles argues that leaders’ impact can indeed be isolated—thanks to the genomes of kings like Charles.

In theory, each round of inbreeding should have made monarchs slightly stupider—and thus worse at their jobs. This yields a natural experiment. Assuming that countries’ propensity for incest did not vary based on their political fortunes, the periods in which they had highly inbred (and probably dim-witted) leaders occurred at random intervals.

The authors analysed 331 European monarchs between 990 and 1800. They first calculated how inbred each ruler was, and then assessed countries’ success during their reigns using two measures: historians’ subjective scores, and the change in land area controlled by each monarch. The authors only compared each ruler against their own country’s historical averages.

“At the global level, this is quite the biggest mortality shock since the Spanish flu,” s

Covid drove a 17% jump in deaths worldwide, he said in an interview. The flu pandemic that began in 1918 killed at least 50 million people. 

The evidence suggests the mortality surge is a direct result of Covid-19, the researchers said. But some deaths may also have occurred indirectly, they said, caused by a lack of access to health care and other essential services during the pandemic, or from behavioral shifts that led to suicide or drug abuse.

KIM WEHLE: B is to break a problem down into smaller pieces

I is to identify our values. A lot of people think lawyers are really about winning all the time. But the law is based on a value system. And I suggest that people be very deliberate about what matters to them with whatever decision there is

The former president spoke at Stanford University on April 21 to lay out his vision for fighting disinformation on the Internet. His focus on the subject is fitting; the dusk of his administration marked a turning point from techno-optimism to pessimism after election interference revealed how easily malicious actors could exploit the free flow of information.

His diagnosis is on target. The Internet has given us access to more people, more opportunities and more knowledge

This has helped activists drum up attention for overlooked causes. It has also enabled the nation’s adversaries to play on our preexisting prejudices and divisions to sow discord

If heat waves were as deadly as the press proclaims, Homo sapiens couldn’t have survived thousands of years without air conditioning. Yet here we are

Humans have shown remarkable resilience and adaptation—at least until modern times, when half of society lost its cool over climate change.

it’s alarmist stories about bad weather that are fueling mental derangements worthy of the DSM-5—not the warm summer air itself.

Christian Petzold likes terrible, irreversible events: accidents, suicides, eternal separations. In his melodramas, Petzold has established a fascination with the trope of love lost at the hands of misrecognition. At the crossroads of historical circumstance and feelings of personal guilt and shame, his protagonists carry burdensome secrets, with devastating consequences.

His latest film at first appears to diverge from recent work. Set in contemporary seaside Germany, Afire takes a break from the backdrops of extreme repression and deprivation that the director has favored for at least a decade

fire is really a slow build to the disaster that Petzold does so well. Only by dint of calamitous events, it seems, can Leon awaken to the reality he resolutely shuts out. The arrival of a forest fire, suddenly overwhelming the plotless plot, seems to satisfy a perverse fantasy grounded in the belief that extremity is required for a life lived fully.

Sexual desire and frustration, familiar feelings for the outcast teenage nerd, pervade the social internet. S3xy-ness is everywhere. Posts by women are dismayingly likely to produce advances, or threats, from creepers on all platforms; at the same time, sex appeal is a pillar for the influencer economy, or else a viable and even noble way to win financial independence. The internet is for porn, as the song goes.

In all these ways, online life today descends from where it started, as a safe harbor for the computer nerds who made it. They were socially awkward, concerned with machines instead of people, and devoted to the fantasy of converting their impotence into power.

When that conversion was achieved, and the nerds took over the world, they adopted the bravado of the jocks they once despised. (Zuck-Musk cage match, anyone?) But they didn’t stop being nerds. We, the public, never agreed to adopt their worldview as the basis for political, social, or aesthetic life. We got it nevertheless.

Von Neumann, too, was deeply concerned about the inability of humanity to keep up with its own inventions. “What we are creating now,” he said to his wife Klári in 1945, “is a monster whose influence is going to change history, provided there is any history left.” Moving to the subject of future computing machines he became even more agitated, foreseeing disaster if “people” could not “keep pace with what they create.”

Oppenheimer, Einstein, von Neumann and other Institute faculty channeled much of their effort toward what AI researchers today call the “alignment” problem: how to make sure our discoveries serve us instead of destroying us. Their approaches to this increasingly pressing problem remain instructive.

Von Neumann focused on applying the powers of mathematical logic, taking insights from games of strategy and applying them to economics and war planning. Today, descendants of his “game theory” running on von Neumann computing architecture are applied not only to our nuclear strategy, but also many parts of our political, economic and social lives. This is one approach to alignment: humanity survives technology through more technology, and it is the researcher’s role to maximize progress.

Andy Clark admits it’s strange that he took up “predictive processing,” an ambitious leading theory of how the brain works. A philosopher of mind at the University of Sussex, he has devoted his career to how thinking doesn’t occur just between the ears—that it flows through our bodies, tools, and environments. “The external world is functioning as part of our cognitive machinery

But 15 years ago, he realized that had to come back to the center of the system: the brain. And he found that predictive processing provided the essential links among the brain, body, and world.

There’s a traditional view that goes back at least to Descartes that perception was about the imprinting of the outside world onto the sense organs. In 20th-century artificial intelligence and neuroscience, vision was a feed-forward process in which you took in pixel-level information, refined it into a two and a half–dimensional sketch, and then refined that into a full world model.

for the past few years, these books have been written by Colleen Hoover.

What is it about Hoover’s stories — which dwell largely in romance, but also include a thriller and a ghost story — that women are drawn to?

I slorped down three of them in one week. I found myself carrying them from room to room, slipping in what would begin as “just a few pages” but then stretch into hours’ worth.

if all of those bad presentations really led to broad societal ills, the proof is hard to find.

Some scientists have tried to take a formal measure of the alleged PowerPoint Effect, asking whether the software really influences our ability to process information. Sebastian Kernbach, a professor of creativity and design at the University of St. Gallen, in Switzerland, has co-authored multiple reviews synthesizing this literature. On the whole, he told me, the research suggests that Tufte was partly right, partly wrong. PowerPoint doesn’t seem to make us stupid—there is no evidence of lower information retention or generalized cognitive decline, for example, among those who use it—but it does impose a set of assumptions about how information ought to be conveyed: loosely, in bullet points, and delivered by presenters to an audience of passive listeners. These assumptions have even reshaped the physical environment for the slide-deck age, Kernbach said: Seminar tables, once configured in a circle, have been bent, post-PowerPoint, into a U-shape to accommodate presenters.

When I spoke with Kernbach, he was preparing for a talk on different methods of visual thinking to a group of employees at a large governmental organization. He said he planned to use a flip chart, draw on blank slides like a white board, and perhaps even have audience members do some drawing of their own. But he was also gearing up to use regular old PowerPoint slides. Doing so, he told me, would “signal preparation and professionalism” for his audience. The organization was NASA.

The five biggest technology giants in the U.S. have collectively lost more than $2 trillion of stock market value this year.

Start-up founders who were turning away eager investors a few months ago now must make an effort to get more money. (Gasp.)

Every couple of years for the past decade, anytime there were some wobbles in technology or moments of doubt, smart people predicted that the growth of the tech economy since the Great Recession couldn’t possibly last.
