Our approach, which borrows from physics and in particular the work of Richard Feynman, goes under the bonnet. It attempts to capture the mathematical structure of the phenomenon – in this case, the pandemic – and to understand the causes of what is observed. Since we don’t know all the causes, we have to infer them. But that inference, and implicit uncertainty, is built into the models

That’s why we call them generative models, because they contain everything you need to know to generate the data. As more data comes in, you adjust your beliefs about the causes, until your model simulates the data as accurately and as simply as possible.

A common type of epidemiological model used today is the SEIR model, which considers that people must be in one of four states – susceptible (S), exposed (E), infected (I) or recovered (R). Unfortunately, reality doesn’t break them down so neatly. For example, what does it mean to be recovered?

The best way to approach this question, he replied, is to look at the trajectory of American democracy over the past decade and a half or so.

increasingly concerned by how politically polarized America was becoming, and polarization has only worsened over the past dozen years. “

Things change, sometimes for the better, sometimes for the worse; you can’t just extrapolate from the present. “

“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. 

WhatsApp, the most popular messaging service worldwide, gained more than two and a half billion active users from 2012 to 2023, and is projected to grow 18 percent more by 2025

In a recent survey of roughly 1,000 Americans, 66 percent said they’ve felt overwhelmed by their group messages, and 42 percent said that group chats can feel like a part-time job.

with X (formerly known as Twitter) in a state of disarray, Facebook falling out of favor, and Instagram taken over by ads, social media is feeling less and less social.

Schools and parenting guides instruct children in how to cultivate empathy, as do workplace culture and wellness programs. You could fill entire bookshelves with guides to finding, embracing and sharing empathy. Few books or lesson plans extol sympathy’s virtues.

“Sympathy focuses on offering support from a distance,” a therapist explains on LinkedIn, whereas empathy “goes beyond sympathy by actively immersing oneself in another person’s emotions and attempting to comprehend their point of view.”

In use since the 16th century, when the Greek “syn-” (“with”) combined with pathos (experience, misfortune, emotion, condition) to mean “having common feelings,” sympathy preceded empathy by a good four centuries

as Netanyahu soon made clear, when it comes to AI, he believes that bad outcomes are the likely outcomes. The Israeli leader interrogated OpenAI’s Brockman about the impact of his company’s creations on the job market. By replacing more and more workers, Netanyahu argued, AI threatens to “cannibalize a lot more jobs than you create,” leaving many people adrift and unable to contribute to the economy. When Brockman suggested that AI could usher in a world where people would not have to work, Netanyahu countered that the benefits of the technology were unlikely to accrue to most people, because the data, computational power, and engineering talent required for AI are concentrated in a few countries.

“You have these trillion-dollar [AI] companies that are produced overnight, and they concentrate enormous wealth and power with a smaller and smaller number of people,” the Israeli leader said, noting that even a free-market evangelist like himself was unsettled by such monopolization. “That will create a bigger and bigger distance between the haves and the have-nots, and that’s another thing that causes tremendous instability in our world. And I don’t know if you have an idea of how you overcome that?”

The other panelists did not. Brockman briefly pivoted to talk about OpenAI’s Israeli employees before saying, “The world we should shoot for is one where all the boats are rising.” But other than mentioning the possibility of a universal basic income for people living in an AI-saturated society, Brockman agreed that “creative solutions” to this problem were needed—without providing any.

In February 1973, Dr. Bernard Beitman found himself hunched over a kitchen sink in an old Victorian house in San Francisco, choking uncontrollably. He wasn’t eating or drinking, so there was nothing to cough up, and yet for several minutes he couldn’t catch his breath or swallow.The next day his brother called to tell him that 3,000 miles away, in Wilmington, Del., their father had died. He had bled into his throat, choking on his own blood at the same time as Beitman’s mysterious episode.

Overcome with awe and emotion, Beitman became fascinated with what he calls meaningful coincidences. After becoming a professor of psychiatry at the University of Missouri-Columbia, he published several papers and two books on the subject and started a nonprofit, the Coincidence Project, to encourage people to share their coincidence stories.

“What I look for as a scientist and a spiritual seeker are the patterns that lead to meaningful coincidences,” said Beitman, 80, from his home in Charlottesville, Va. “So many people are reporting this kind of experience. Understanding how it happens is part of the fun.”

Social scientists have identified at least three major forces that collectively bind together successful democracies: social capital (extensive social networks with high levels of trust), strong institutions, and shared stories.

Social media has weakened all three.

gradually, social-media users became more comfortable sharing intimate details of their lives with strangers and corporations. As I wrote in a 2019 Atlantic article with Tobias Rose-Stockwell, they became more adept at putting on performances and managing their personal brand—activities that might impress others but that do not deepen friendships in the way that a private phone conversation will.

I’ve done my best to pull out the recurring themes I’ve observed from these 100 conversations.

I have come to believe that there are six forces that help form friendships and maintain them through the years: accumulation, attention, intention, ritual, imagination, and grace.

The simplest and most obvious force that forms and sustains friendships is time spent together. One study estimates that it takes spending 40 to 60 hours together within the first six weeks of meeting to turn an acquaintance into a casual friend, and about 80 to 100 hours to become more than that.

Satya Doyle Byock, a 39-year-old therapist, noticed a shift in tone over the past few years in the young people who streamed into her office: frenetic, frazzled clients in their late teens, 20s and 30s. They were unnerved and unmoored, constantly feeling like something was wrong with them.

“Crippling anxiety, depression, anguish, and disorientation are effectively the norm,”

her new book, “Quarterlife: The Search for Self in Early Adulthood.” The book uses anecdotes from Ms. Byock’s practice to outline obstacles faced by today’s young adults — roughly between the ages of 16 and 36 — and how to deal with them.
