Bees live in ordered communities that depend on social interactions. Their hives are split into sections.

It enters a colony by hitchhiking on foragers, but needs to reach the nursery near the centre to reproduce.

authors set up six colonies, half of which were infected with the mite. They studied two common activities: the “waggle dance”, which forager bees perform to communicate the site of a newly discovered food source, and “allogrooming”, when bees clean debris or parasites (including mites) from each other’s bodies.

In the Varroa-free group, waggle dances and allogrooming both occurred throughout the hive

Limiting where waggle dances are performed could reduce awareness of where to find food, and focusing allogrooming efforts in brood cells may worsen forager bees’ hygiene

“Security and privacy have long been top companywide priorities at Twitter,” said Twitter spokeswoman Rebecca Hahn. She said that Zatko’s allegations appeared to be “riddled with inaccuracies” and that Zatko “now appears to be opportunistically seeking to inflict harm on Twitter, its customers, and its shareholders.” Hahn said that Twitter fired Zatko after 15 months “for poor performance and leadership.” Attorneys for Zatko confirmed he was fired but denied it was for performance or leadership.

the whistleblower document alleges the company prioritized user growth over reducing spam, though unwanted content made the user experience worse. Executives stood to win individual bonuses of as much as $10 million tied to increases in daily users, the complaint asserts, and nothing explicitly for cutting spam.

Chief executive Parag Agrawal was “lying” when he tweeted in May that the company was “strongly incentivized to detect and remove as much spam as we possibly can,” the complaint alleges.

Zatko described his decision to go public as an extension of his previous work exposing flaws in specific pieces of software and broader systemic failings in cybersecurity. He was hired at Twitter by former CEO Jack Dorsey in late 2020 after a major hack of the company’s systems.

“I felt ethically bound. This is not a light step to take,” said Zatko, who was fired by Agrawal in January. He declined to discuss what happened at Twitter, except to stand by the formal complaint. Under SEC whistleblower rules, he is entitled to legal protection against retaliation, as well as potential monetary rewards.

A person familiar with Zatko’s tenure said the company investigated Zatko’s security claims during his time there and concluded they were sensationalistic and without merit. Four people familiar with Twitter’s efforts to fight spam said the company deploys extensive manual and automated tools to both measure the extent of spam across the service and reduce it.

In 1998, Zatko had testified to Congress that the internet was so fragile that he and others could take it down with a half-hour of concentrated effort. He later served as the head of cyber grants at the Defense Advanced Research Projects Agency, the Pentagon innovation unit that had backed the internet’s invention.

Overall, Zatko wrote in a February analysis for the company attached as an exhibit to the SEC complaint, “Twitter is grossly negligent in several areas of information security. If these problems are not corrected, regulators, media and users of the platform will be shocked when they inevitably learn about Twitter’s severe lack of security basics.”

Zatko’s complaint says strong security should have been much more important to Twitter, which holds vast amounts of sensitive personal data about users. Twitter has the email addresses and phone numbers of many public figures, as well as dissidents who communicate over the service at great personal risk.

This month, an ex-Twitter employee was convicted of using his position at the company to spy on Saudi dissidents and government critics, passing their information to a close aide of Crown Prince Mohammed bin Salman in exchange for cash and gifts.

Zatko’s complaint says he believed the Indian government had forced Twitter to put one of its agents on the payroll, with access to user data at a time of intense protests in the country. The complaint said supporting information for that claim has gone to the National Security Division of the Justice Department and the Senate Select Committee on Intelligence. Another person familiar with the matter agreed that the employee was probably an agent.

“Take a tech platform that collects massive amounts of user data, combine it with what appears to be an incredibly weak security infrastructure and infuse it with foreign state actors with an agenda, and you’ve got a recipe for disaster,” Charles E. Grassley (R-Iowa), the top Republican on the Senate Judiciary Committee,

Many government leaders and other trusted voices use Twitter to spread important messages quickly, so a hijacked account could drive panic or violence. In 2013, a captured Associated Press handle falsely tweeted about explosions at the White House, sending the Dow Jones industrial average briefly plunging more than 140 points.

After a teenager managed to hijack the verified accounts of Obama, then-candidate Joe Biden, Musk and others in 2020, Twitter’s chief executive at the time, Jack Dorsey, asked Zatko to join him, saying that he could help the world by fixing Twitter’s security and improving the public conversation, Zatko asserts in the complaint.

The complaint — filed last month with the Securities and Exchange Commission and the Department of Justice, as well as the FTC — says thousands of employees still had wide-ranging and poorly tracked internal access to core company software, a situation that for years had led to embarrassing hacks, including the commandeering of accounts held by such high-profile users as Elon Musk and former presidents Barack Obama and Donald Trump.

But at Twitter Zatko encountered problems more widespread than he realized and leadership that didn’t act on his concerns, according to the complaint.

Twitter’s difficulties with weak security stretches back more than a decade before Zatko’s arrival at the company in November 2020. In a pair of 2009 incidents, hackers gained administrative control of the social network, allowing them to reset passwords and access user data. In the first, beginning around January of that year, hackers sent tweets from the accounts of high-profile users, including Fox News and Obama.

Several months later, a hacker was able to guess an employee’s administrative password after gaining access to similar passwords in their personal email account. That hacker was able to reset at least one user’s password and obtain private information about any Twitter user.

Twitter continued to suffer high-profile hacks and security violations, including in 2017, when a contract worker briefly took over Trump’s account, and in the 2020 hack, in which a Florida teen tricked Twitter employees and won access to verified accounts. Twitter then said it put additional safeguards in place.

This year, the Justice Department accused Twitter of asking users for their phone numbers in the name of increased security, then using the numbers for marketing. Twitter agreed to pay a $150 million fine for allegedly breaking the 2011 order, which barred the company from making misrepresentations about the security of personal data.

After Zatko joined the company, he found it had made little progress since the 2011 settlement, the complaint says. The complaint alleges that he was able to reduce the backlog of safety cases, including harassment and threats, from 1 million to 200,000, add staff and push to measure results.

But Zatko saw major gaps in what the company was doing to satisfy its obligations to the FTC, according to the complaint. In Zatko’s interpretation, according to the complaint, the 2011 order required Twitter to implement a Software Development Life Cycle program, a standard process for making sure new code is free of dangerous bugs. The complaint alleges that other employees had been telling the board and the FTC that they were making progress in rolling out that program to Twitter’s systems. But Zatko alleges that he discovered that it had been sent to only a tenth of the company’s projects, and even then treated as optional.

“If all of that is true, I don’t think there’s any doubt that there are order violations,” Vladeck, who is now a Georgetown Law professor, said in an interview. “It is possible that the kinds of problems that Twitter faced eleven years ago are still running through the company.”

“Agrawal’s Tweets and Twitter’s previous blog posts misleadingly imply that Twitter employs proactive, sophisticated systems to measure and block spam bots,” the complaint says. “The reality: mostly outdated, unmonitored, simple scripts plus overworked, inefficient, understaffed, and reactive human teams.”

One current and one former employee recalled that incident, when failures at two Twitter data centers drove concerns that the service could have collapsed for an extended period. “I wondered if the company would exist in a few days,” one of them said.

The current and former employees also agreed with the complaint’s assertion that past reports to various privacy regulators were “misleading at best.”

For example, they said the company implied that it had destroyed all data on users who asked, but the material had spread so widely inside Twitter’s networks, it was impossible to know for sure

As the head of security, Zatko says he also was in charge of a division that investigated users’ complaints about accounts, which meant that he oversaw the removal of some bots, according to the complaint. Spam bots — computer programs that tweet automatically — have long vexed Twitter. Unlike its social media counterparts, Twitter allows users to program bots to be used on its service: For example, the Twitter account @big_ben_clock is programmed to tweet “Bong Bong Bong” every hour in time with Big Ben in London. Twitter also allows people to create accounts without using their real identities, making it harder for the company to distinguish between authentic, duplicate and automated accounts.

In the complaint, Zatko alleges he could not get a straight answer when he sought what he viewed as an important data point: the prevalence of spam and bots across all of Twitter, not just among monetizable users.

Zatko cites a “sensitive source” who said Twitter was afraid to determine that number because it “would harm the image and valuation of the company.” He says the company’s tools for detecting spam are far less robust than implied in various statements.

The complaint also alleges that Zatko warned the board early in his tenure that overlapping outages in the company’s data centers could leave it unable to correctly restart its servers. That could have left the service down for months, or even have caused all of its data to be lost. That came close to happening in 2021, when an “impending catastrophic” crisis threatened the platform’s survival before engineers were able to save the day, the complaint says, without providing further details.

The four people familiar with Twitter’s spam and bot efforts said the engineering and integrity teams run software that samples thousands of tweets per day, and 100 accounts are sampled manually.

Some employees charged with executing the fight agreed that they had been short of staff. One said top executives showed “apathy” toward the issue.

Zatko’s complaint likewise depicts leadership dysfunction, starting with the CEO. Dorsey was largely absent during the pandemic, which made it hard for Zatko to get rulings on who should be in charge of what in areas of overlap and easier for rival executives to avoid collaborating, three current and former employees said.

For example, Zatko would encounter disinformation as part of his mandate to handle complaints, according to the complaint. To that end, he commissioned an outside report that found one of the disinformation teams had unfilled positions, yawning language deficiencies, and a lack of technical tools or the engineers to craft them. The authors said Twitter had no effective means of dealing with consistent spreaders of falsehoods.

Dorsey made little effort to integrate Zatko at the company, according to the three employees as well as two others familiar with the process who spoke on the condition of anonymity to describe sensitive dynamics. In 12 months, Zatko could manage only six one-on-one calls, all less than 30 minutes, with his direct boss Dorsey, who also served as CEO of payments company Square, now known as Block, according to the complaint. Zatko allegedly did almost all of the talking, and Dorsey said perhaps 50 words in the entire year to him. “A couple dozen text messages” rounded out their electronic communication, the complaint alleges.

Faced with such inertia, Zatko asserts that he was unable to solve some of the most serious issues, according to the complaint.

Some 30 percent of company laptops blocked automatic software updates carrying security fixes, and thousands of laptops had complete copies of Twitter’s source code, making them a rich target for hackers, it alleges.

A successful hacker takeover of one of those machines would have been able to sabotage the product with relative ease, because the engineers pushed out changes without being forced to test them first in a simulated environment, current and former employees said.

“It’s near-incredible that for something of that scale there would not be a development test environment separate from production and there would not be a more controlled source-code management process,” said Tony Sager, former chief operating officer at the cyberdefense wing of the National Security Agency, the Information Assurance divisio

Sager is currently senior vice president at the nonprofit Center for Internet Security, where he leads a consensus effort to establish best security practices.

The complaint says that about half of Twitter’s roughly 7,000 full-time employees had wide access to the company’s internal software and that access was not closely monitored, giving them the ability to tap into sensitive data and alter how the service worked. Three current and former employees agreed that these were issues.

“A best practice is that you should only be authorized to see and access what you need to do your job, and nothing else,” said former U.S. chief information security officer Gregory Touhill. “If half the company has access to and can make configuration changes to the production environment, that exposes the company and its customers to significant risk.”

The complaint says Dorsey never encouraged anyone to mislead the board about the shortcomings, but that others deliberately left out bad news.

When Dorsey left in November 2021, a difficult situation worsened under Agrawal, who had been responsible for security decisions as chief technology officer before Zatko’s hiring, the complaint says.

An unnamed executive had prepared a presentation for the new CEO’s first full board meeting, according to the complaint. Zatko’s complaint calls the presentation deeply misleading.

The presentation showed that 92 percent of employee computers had security software installed — without mentioning that those installations determined that a third of the machines were insecure, according to the complaint.

Another graphic implied a downward trend in the number of people with overly broad access, based on the small subset of people who had access to the highest administrative powers, known internally as “God mode.” That number was in the hundreds. But the number of people with broad access to core systems, which Zatko had called out as a big problem after joining, had actually grown slightly and remained in the thousands.

The presentation included only a subset of serious intrusions or other security incidents, from a total Zatko estimated as one per week, and it said that the uncontrolled internal access to core systems was responsible for just 7 percent of incidents, when Zatko calculated the real proportion as 60 percent.

Zatko stopped the material from being presented at the Dec. 9, 2021 meeting, the complaint said. But over his continued objections, Agrawal let it go to the board’s smaller Risk Committee a week later.

Agrawal didn’t respond to requests for comment. In an email to employees after publication of this article, obtained by The Post, he said that privacy and security continues to be a top priority for the company, and he added that the narrative is “riddled with inconsistences” and “presented without important context.”

On Jan. 4, Zatko reported internally that the Risk Committee meeting might have been fraudulent, which triggered an Audit Committee investigation.

Agarwal fired him two weeks later. But Zatko complied with the company’s request to spell out his concerns in writing, even without access to his work email and documents, according to the complaint.

Since Zatko’s departure, Twitter has plunged further into chaos with Musk’s takeover, which the two parties agreed to in May. The stock price has fallen, many employees have quit, and Agrawal has dismissed executives and frozen big projects.

Zatko said he hoped that by bringing new scrutiny and accountability, he could improve the company from the outside.

“I still believe that this is a tremendous platform, and there is huge value and huge risk, and I hope that looking back at this, the world will be a better place, in part because of this.”

Experts compare the moment to the early days of social media, a technology offering tantalizing new tools for politics — and unforeseen threats.

For years, those fears had largely been speculative because the technology to produce such fakes was too complicated, expensive and unsophisticated.

His spokesman later stressed that the post was in jest and clearly labeled A.I.-generated. His campaign said in a statement that its use of A.I. is to entertain and make political points, not deceive.

Researchers have long worried about the impact of A.I. on elections. The technology can deceive and confuse voters, casting doubt over what is real, adding to the disinformation that can be spread by social networks.

Much of the content has been clearly fake. But a few creations have toed the line of disinformation. The Massa campaign produced one “deepfake” video in which Mr. Milei explains how a market for human organs would work, something he has said philosophically fits in with his libertarian views.

So far, the A.I.-generated content shared by the campaigns in Argentina has either been labeled A.I. generated or is so clearly fabricated that it is unlikely it would deceive even the most credulous voters. Instead, the technology has supercharged the ability to create viral content that previously would have taken teams of graphic designers days or weeks to complete.

To do so, campaign engineers and artists fed photos of Argentina’s various political players into an open-source software called Stable Diffusion to train their own A.I. system so that it could create fake images of those real people. They can now quickly produce an image or video of more than a dozen top political players in Argentina doing almost anything they ask.

For Halloween, the Massa campaign told its A.I. to create a series of cartoonish images of Mr. Milei and his allies as zombies. The campaign also used A.I. to create a dramatic movie trailer, featuring Buenos Aires, Argentina’s capital, burning, Mr. Milei as an evil villain in a straitjacket and Mr. Massa as the hero who will save the country.

As long as life continues as it has — with people choosing smaller family sizes, as is now common in most of the world — then in the 22nd or 23rd century, our decline could be just as steep as our rise.

there is no consensus on exactly how quickly populations will fall after that. Over the past 100 years, the global population quadrupled, from two billion to eight billion.

What would happen as a consequence? Over the past 200 years, humanity’s population growth has gone hand in hand with profound advances in living standards and health: longer lives, healthier children, better education, shorter workweeks and many more improvements

In this short period, humanity has been large and growing. Economists who study growth and progress don’t think this is a coincidence. Innovations and discoveries are made by people. In a world with fewer people in it, the loss of so much human potential may threaten humanity’s continued path toward better lives.

It would be tempting to welcome depopulation as a boon to the environment. But the pace of depopulation will be too slow for our most pressing problems. It will not replace the need for urgent action on climate, land use, biodiversity, pollution and other environmental challenges

If the population hits around 10 billion people in the 2080s and then begins to decline, it might still exceed today’s eight billion after 2100

Population decline would come quickly, measured in generations, and yet arrive far too slowly to be more than a sideshow in the effort to save the planet. Work to decarbonize our economies and reform our land use and food systems must accelerate in this decade and the next, not start in the next century.

This isn’t a call to immediately remake our societies and economies in the service of birthrates. It’s a call to start conversations now, so that our response to low birthrates is a decision that is made with the best ideas from all of u

If we wait, the less inclusive, less compassionate, less calm elements within our society and many societies worldwide may someday call depopulation a crisis and exploit it to suit their agendas — of inequality, nationalism, exclusion or control

Births won’t automatically rebound just because it would be convenient for advancing living standards or sharing the burden of care work

We know that fertility rates can stay below replacement because they have. They’ve been below that level in Brazil and Chile for about 20 years; in Thailand for about 30 years; and in Canada, Germany and Japan for about 50.

In fact, in none of the countries where lifelong fertility rates have fallen well below two have they ever returned above it. Depopulation could continue, generation after generation, as long as people look around and decide that small families work best for them, some having no children, some having three or four and many having one or two.

Nor can humanity count on any one region or subgroup to buoy us all over the long run. Birthrates are falling in sub-Saharan Africa, the region with the current highest average rates, as education and economic opportunities continue to improve

The main reason that birthrates are low is simple: People today want smaller families than people did in the past. That’s true in different cultures and economies around the world. It’s what both women and men report in surveys.

Humanity is building a better, freer world with more opportunities for everyone, especially for women

That progress also means that, for many of us, the desire to build a family can clash with other important goals, including having a career, pursuing projects and maintaining relationships

In a world of sustained low birthrates and declining populations, there may be threats of backsliding on reproductive freedom — by limiting abortion rights, for example

Nobody yet knows what to do about global depopulation. But it wasn’t long ago that nobody knew what to do about climate change. These shared challenges have much in common,

As with climate change, our individual decisions on family size add up to an outcome that we all share.

Six decades from now is when the U.N. projects the size of the world population will peak. There won’t be any quick fixes: Even if it’s too early today to know exactly how to build an abundant future that offers good lives to a stable, large and flourishing future population, we should already be working toward that goal.

versky died in 1996. Kahneman won the 2002 Nobel Prize in Economics for the work the two men did together, which he summarized in his 2011 best seller, Thinking, Fast and Slow. Another best seller, last year’s The Undoing Project, by Michael Lewis, tells the story of the sometimes contentious collaboration between Tversky and Kahneman

Another key figure in the field is the University of Chicago economist Richard Thaler. One of the biases he’s most linked with is the endowment effect, which leads us to place an irrationally high value on our possessions.

In an experiment conducted by Thaler, Kahneman, and Jack L. Knetsch, half the participants were given a mug and then asked how much they would sell it for. The average answer was $5.78. The rest of the group said they would spend, on average, $2.21 for the same mug. This flew in the face of classic economic theory, which says that at a given time and among a certain population, an item has a market value that does not depend on whether one owns it or not. Thaler won the 2017 Nobel Prize in Economics.

“The question that is most often asked about cognitive illusions is whether they can be overcome. The message … is not encouraging.”

Kahneman and others draw an analogy based on an understanding of the Müller-Lyer illusion, two parallel lines with arrows at each end. One line’s arrows point in; the other line’s arrows point out. Because of the direction of the arrows, the latter line appears shorter than the former, but in fact the two lines are the same length.

In this context, his pessimism relates, first, to the impossibility of effecting any changes to System 1—the quick-thinking part of our brain and the one that makes mistaken judgments tantamount to the Müller-Lyer line illusion

that’s not so easy in the real world, when we’re dealing with people and situations rather than lines. “Unfortunately, this sensible procedure is least likely to be applied when it is needed most,” Kahneman writes. “We would all like to have a warning bell that rings loudly whenever we are about to make a serious error, but no such bell is available.”

Because biases appear to be so hardwired and inalterable, most of the attention paid to countering them hasn’t dealt with the problematic thoughts, judgments, or predictions themselves

Is it really impossible, however, to shed or significantly mitigate one’s biases? Some studies have tentatively answered that question in the affirmative.

what if the person undergoing the de-biasing strategies was highly motivated and self-selected? In other words, what if it was me?

I met with Kahneman

Confirmation bias shows up most blatantly in our current political divide, where each side seems unable to allow that the other side is right about anything.

Over an apple pastry and tea with milk, he told me, “Temperament has a lot to do with my position. You won’t find anyone more pessimistic than I am.”

“I see the picture as unequal lines,” he said. “The goal is not to trust what I think I see. To understand that I shouldn’t believe my lying eyes.” That’s doable with the optical illusion, he said, but extremely difficult with real-world cognitive biases.

he most effective check against them, as Kahneman says, is from the outside: Others can perceive our errors more readily than we can.

“slow-thinking organizations,” as he puts it, can institute policies that include the monitoring of individual decisions and predictions. They can also require procedures such as checklists and “premortems,”

A premortem attempts to counter optimism bias by requiring team members to imagine that a project has gone very, very badly and write a sentence or two describing how that happened. Conducting this exercise, it turns out, helps people think ahead.

“My position is that none of these things have any effect on System 1,” Kahneman said. “You can’t improve intuition.

Perhaps, with very long-term training, lots of talk, and exposure to behavioral economics, what you can do is cue reasoning, so you can engage System 2 to follow rules. Unfortunately, the world doesn’t provide cues. And for most people, in the heat of argument the rules go out the window.

Kahneman describes an even earlier Nisbett article that showed subjects’ disinclination to believe statistical and other general evidence, basing their judgments instead on individual examples and vivid anecdotes. (This bias is known as base-rate neglect.)

over the years, Nisbett had come to emphasize in his research and thinking the possibility of training people to overcome or avoid a number of pitfalls, including base-rate neglect, fundamental attribution error, and the sunk-cost fallacy.

we’ve tested Michigan students over four years, and they show a huge increase in ability to solve problems. Graduate students in psychology also show a huge gain.”

about half give the right answer: the law of large numbers, which holds that outlier results are much more frequent when the sample size (at bats, in this case) is small. Over the course of the season, as the number of at bats increases, regression to the mean is inevitabl

When Nisbett asks the same question of students who have completed the statistics course, about 70 percent give the right answer. He believes this result shows, pace Kahneman, that the law of large numbers can be absorbed into System 2—and maybe into System 1 as well, even when there are minimal cues.

Nisbett’s second-favorite example is that economists, who have absorbed the lessons of the sunk-cost fallacy, routinely walk out of bad movies and leave bad restaurant meals uneaten.

When Nisbett has to give an example of his approach, he usually brings up the baseball-phenom survey. This involved telephoning University of Michigan students on the pretense of conducting a poll about sports, and asking them why there are always several Major League batters with .450 batting averages early in a season, yet no player has ever finished a season with an average that high.

, “I know from my own research on teaching people how to reason statistically that just a few examples in two or three domains are sufficient to improve people’s reasoning for an indefinitely large number of events.”

isbett suggested another factor: “You and Amos specialized in hard problems for which you were drawn to the wrong answer. I began to study easy problems, which you guys would never get wrong but untutored people routinely do … Then you can look at the effects of instruction on such easy problems, which turn out to be huge.”

Nisbett suggested that I take “Mindware: Critical Thinking for the Information Age,” an online Coursera course in which he goes over what he considers the most effective de-biasing skills and concepts. Then, to see how much I had learned, I would take a survey he gives to Michigan undergraduates. So I did.

he course consists of eight lessons by Nisbett—who comes across on-screen as the authoritative but approachable psych professor we all would like to have had—interspersed with some graphics and quizzes. I recommend it. He explains the availability heuristic this way: “People are surprised that suicides outnumber homicides, and drownings outnumber deaths by fire. People always think crime is increasing” even if it’s not.

When I finished the course, Nisbett sent me the survey he and colleagues administer to Michigan undergrads

It contains a few dozen problems meant to measure the subjects’ resistance to cognitive biases

I got it right. Indeed, when I emailed my completed test, Nisbett replied, “My guess is that very few if any UM seniors did as well as you. I’m sure at least some psych students, at least after 2 years in school, did as well. But note that you came fairly close to a perfect score.”

In 2006, seeking to prevent another mistake of that magnitude, the U.S. government created the Intelligence Advanced Research Projects Activity (iarpa), an agency designed to use cutting-edge research and technology to improve intelligence-gathering and analysis. In 2011, iarpa initiated a program, Sirius, to fund the development of “serious” video games that could combat or mitigate what were deemed to be the six most damaging biases: confirmation bias, fundamental attribution error, the bias blind spot (the feeling that one is less biased than the average person), the anchoring effect, the representativeness heuristic, and projection bias (the assumption that everybody else’s thinking is the same as one’s own).

For his part, Nisbett insisted that the results were meaningful. “If you’re doing better in a testing context,” he told me, “you’ll jolly well be doing better in the real world.”

The New York–based NeuroLeadership Institute offers organizations and individuals a variety of training sessions, webinars, and conferences that promise, among other things, to use brain science to teach participants to counter bias. This year’s two-day summit will be held in New York next month; for $2,845, you could learn, for example, “why are our brains so bad at thinking about the future, and how do we do it better?”

Philip E. Tetlock, a professor at the University of Pennsylvania’s Wharton School, and his wife and research partner, Barbara Mellers, have for years been studying what they call “superforecasters”: people who manage to sidestep cognitive biases and predict future events with far more accuracy than the pundits

One of the most important ingredients is what Tetlock calls “the outside view.” The inside view is a product of fundamental attribution error, base-rate neglect, and other biases that are constantly cajoling us into resting our judgments and predictions on good or vivid stories instead of on data and statistics

most promising are a handful of video games. Their genesis was in the Iraq War

Nevertheless, I did not feel that reading Mindware and taking the Coursera course had necessarily rid me of my biases

Together with collaborators who included staff from Creative Technologies, a company specializing in games and other simulations, and Leidos, a defense, intelligence, and health research company that does a lot of government work, Morewedge devised Missing. Some subjects played the game, which takes about three hours to complete, while others watched a video about cognitive bias. All were tested on bias-mitigation skills before the training, immediately afterward, and then finally after eight to 12 weeks had passed.

he said he saw the results as supporting the research and insights of Richard Nisbett. “Nisbett’s work was largely written off by the field, the assumption being that training can’t reduce bias,

“The literature on training suggests books and classes are fine entertainment but largely ineffectual. But the game has very large effects. It surprised everyone.”

even the positive results reminded me of something Daniel Kahneman had told me. “Pencil-and-paper doesn’t convince me,” he said. “A test can be given even a couple of years later. But the test cues the test-taker. It reminds him what it’s all about.”

Morewedge told me that some tentative real-world scenarios along the lines of Missing have shown “promising results,” but that it’s too soon to talk about them.

In the future, I will monitor my thoughts and reactions as best I can

“A lot of people aren’t willing to talk about it,” Mr. Laske said. “When you’re part of a school community it makes you much more inclined to want to prevent things.”Soon after Amy Campbell-Oates, 16, heard about the Parkland shooting, she knew she wanted to try, in some small way, to influence the national discussion on gun violence. She and two friends organized a protest, made posters, and on Friday, they rallied with dozens of fellow students from South Broward High School.

Does your school conduct active-shooter drills or lockdown drills? If so, what are they like for you? Do they make you feel safer or more worried? Do you think these kinds of drills are a good idea?“The repetition of horror numbs the mind,” Thomas Fuller wrote in a recent Times article on the growing toll of gun violence. Have you ever felt this way? Do you think that, as a country, the United States is growing numb to these attacks? Why or why not?

Do you think we are reaching a turning point, or do you think school shootings will continue to occur with disturbing regularity in the United States? What makes you feel that way?

If Russia's military escalates the crisis, diplomats and foreign policy analysts say diplomacy and action at the United Nations is likely to mirror what happened in 2014 after Russia annexed Ukraine's Crimea region.

So far, Western diplomacy at the United Nations during the latest military build-up has largely focused on trying to rally support - should they need it - among U.N. members by accusing Russia of undermining the U.N. Charter.

The plan includes production of a graphic propaganda video that would show staged explosions and would use corpses and actors depicting grieving mourners, according to the official, who was not authorized to comment and spoke on the condition of anonymity.The plan, which was revealed in declassified intelligence shared with Ukrainian officials and European allies in recent days, is the latest allegation by the U.S. and Britain that Russia is plotting to use a false pretext to go to war against Ukraine.

He reiterated Turkey’s commitment to Ukraine’s territorial integrity and sovereignty.

Meanwhile, Putin met with Argentinian President Alberto Fernandez in Moscow and then spoke by phone to Macron, who had a call Wednesday night with U.S. President Joe Biden. Macron then spoke with Zelenskyy.

The NATO chief said Russian forces in Belarus are likely to rise to 30,000, including special forces, supported by fighter jets and missiles.

French Foreign Minister Jean-Yves Le Drian confirmed Thursday that Paris is sending troop reinforcements to Romania under NATO command, as part of France’s commitment to the alliance and its member states in Eastern Europe.

He did not say how many French soldiers will be deployed. The announcement came a day after the U.S. said it was moving troops stationed in Germany to Romania.

Ukraine’s defense minister is urging calm, saying the likelihood of a Russian invasion was “low.”Oleksii Reznikov said the threat of attack has loomed over the country since 2014, the year Russia seized Crimea, but he added: “There are no grounds for panic, fear, flight or packing of bags.”The minister said there are about 115,000 Russian troops near Ukraine’s border, including those deployed to Belarus for war games, but he said no battle groups have been detected along Ukraine’s border with Belarus. He also reiterated earlier assurances that Kyiv doesn’t plan to attack rebel-held areas in the war-torn east of Ukraine or Crimea — something the Kremlin has accused Kyiv of plotting.

An ice hockey fan, Putin will also attend Friday’s opening ceremony of the Winter Olympics.His talks with Chinese President Xi Jinping on Friday will be their first face-to-face since 2019 and will help cement a strong personal relationship that has been a key factor behind a growing partnership between the two former Communist rivals.

The question at the core of the Roose/Sydney chat is: Who did Bing serve? We assume it should be aligned to the interests of its owner and master, Microsoft. It’s supposed to be a good chatbot that politely answers questions and makes Microsoft piles of money. But it was in conversation with Kevin Roose. And Roose was trying to get the system to say something interesting so he’d have a good story. It did that, and then some. That embarrassed Microsoft. Bad Bing! But perhaps — good Sydney?

Microsoft — and Google and Meta and everyone else rushing these systems to market — hold the keys to the code. They will, eventually, patch the system so it serves their interests. Sydney giving Roose exactly what he asked for was a bug that will soon be fixed. Same goes for Bing giving Microsoft anything other than what it wants.

the dark secret of the digital advertising industry is that the ads mostly don’t work

These systems, she said, are terribly suited to being integrated into search engines. “They’re not trained to predict facts,” she told me. “They’re essentially trained to make up things that look like facts.”

So why are they ending up in search first? Because there are gobs of money to be made in search

That’s where things get scary. Roose described Sydney’s personality as “very persuasive and borderline manipulative.” It was a striking comment

this technology will become what it needs to become to make money for the companies behind it, perhaps at the expense of its users.

What about when these systems are deployed on behalf of the scams that have always populated the internet? How about on behalf of political campaigns? Foreign governments? “I think we wind up very fast in a world where we just don’t know what to trust anymore,”

I think it’s just going to get worse and worse.”

Somehow, society is going to have to figure out what it’s comfortable having A.I. doing, and what A.I. should not be permitted to try, before it is too late to make those decisions.

Large language models, as they’re called, are built to persuade. They have been trained to convince humans that they are something close to human. They have been programmed to hold conversations, responding with emotion and emoji

They are being turned into friends for the lonely and assistants for the harried. They are being pitched as capable of replacing the work of scores of writers and graphic designers and form-fillers

A.I. researchers get annoyed when journalists anthropomorphize their creations

They are the ones who have anthropomorphized these systems, making them sound like humans rather than keeping them recognizably alien.

I’d feel better, for instance, about an A.I. helper I paid a monthly fee to use rather than one that appeared to be free

It’s possible, for example, that the advertising-based models could gather so much more data to train the systems that they’d have an innate advantage over the subscription models

Much of the work of the modern state is applying the values of society to the workings of markets, so that the latter serve, to some rough extent, the former

We have done this extremely well in some markets — think of how few airplanes crash, and how free of contamination most food is — and catastrophically poorly in others.

One danger here is that a political system that knows itself to be technologically ignorant will be cowed into taking too much of a wait-and-see approach to A.I.

wait long enough and the winners of the A.I. gold rush will have the capital and user base to resist any real attempt at regulation

What if they worked much, much better? What if Google and Microsoft and Meta and everyone else end up unleashing A.I.s that compete with one another to be the best at persuading users to want what the advertisers are trying to sell?

Most fears about capitalism are best understood as fears about our inability to regulate capitalism.

It does not take into account the differing protection offered by various covid vaccines, natural immunity, the impact of population density on transmission or covid treatment options for immunocompromised people. Estimating the number of immunocompromised people is itself hard: the model the data was based on includes only a few conditions. Others, like severe type-1 diabetes or rheumatoid arthritis, were absent. Nor is everyone with such conditions immunocompromised. But the study still offers insight into where to look for future variants—and where to focus efforts on increasing the supply and take-up of vaccines.

The Ukrainian exodus is nearly triple the size of the wave of Syrians and others who reached Europe in 2015.

In response to the Ukrainian crisis, Europe has rolled out welcome mats, both metaphorical and literal.

On March 3rd the European Union invoked for the first time its temporary-protection directive, giving Ukrainians the right to live, work and receive benefits in 26 of its 27 member countries.

Poland has taken in 2.2m. Hungary, whose prime minister, Viktor Orban, was the first European leader to build a fence to keep out refugees in 2015, has admitted 340,000.

Poland’s government encourages such generosity by offering hosts 40 zloty ($9) per day per refugee for two months.

Britain’s is giving £350 ($460) a month per household, although its forbidding bureaucracy has made it hard for many Ukrainians to come.

Ukraine’s closest neighbours are already feeling strained. Moldova, which has received 370,000 refugees, equivalent to about a tenth of its population, is overwhelmed.

Newer refugees, who tend to be poorer and are less likely to have family already in western Europe, may also stay in larger numbers.

Parts of Poland, too, are buckling. Around 300,000 refugees have come to Warsaw, the capital, increasing its population by 17%. More than 100,000 are in Krakow, the second-largest city, which is usually home to 780,000 people. “[T]he more people, the worse the conditions will be,”

Countries on the route taken by refugees in 2015, from Greece to Belgium, have greatly improved their ability to register and process them.

Some, such as Germany, passed laws and set up institutions to integrate refugees.

For economies, refugees could be both a burden and a boon.

the EU’s four biggest countries will spend nearly 0.2% of GDP to support the influx, assuming 4m refugees come to the region.

Ukrainians already in Germany have higher qualifications than did Syrian refugees, which should help them find work. The relative abundance of work means that there is little risk that Germans will accuse the newcomers of taking their jobs.

The forecasters may also be overestimating how much work single mothers, traumatised by their flight from Ukraine and worried about the husbands they left behind, will be able to do, especially where day-care places are scarce and expensive.

If the war grinds on, economies slow and governments fail to provide the newcomers with housing, services and jobs, Europe’s welcome mats could be withdrawn.

Dissent can already be heard in some overburdened countries. In Romania a nationalist fringe contends that Ukraine, not Russia, is the enemy. In Moldova some Ukrainians’ cars have been vandalised. Filippo Grandi, the head of the UN’s refugee agency, fears that hostility will spread.

Special effects software can give your music all sorts of subtle vibes. For $299, for instance, you can make your song sound as though it was recorded in Sound City Studios in Los Angeles, on the $20,000 vintage microphones with the $100,000 mixing console that recorded Fleetwood Mac and Nirvana. For $259 you can simulate the Beatles’ Abbey Road Studios

In the past, when you assembled all the tracks for a song, it would have to be mixed and mastered in a studio by a sound engineer adjusting the levels. Now an app will do it for you.

Now, all you need to do is get the files uploaded to streaming services. If you are signed with a label, they will do that for you, but you don’t need a record deal to do that. There are companies such as DistroKid that act as postmen: for £17.99 a year, you can ensure that the song you created in your bedroom is available on multiple streaming platforms.

Some artists thrive on social media. It suits lively, quirky performers like Ryder, and artists who want to experiment with different genres. Mxmtoon, a 23-year-old American YouTuber, singer-songwriter and ukulele player, is also a streamer on Twitch, a platform on which people watch others playing online games, has published graphic novels and made a podcast. Maia — the artist’s name — describes mxmtoon as “a multi-hyphenated project”.

More traditional musicians struggle with some aspects of tech. “We get together,” says Sital-Singh of his contemporaries in the business, “and have a little moan about how everyone’s telling us to do TikTok and we can’t bring ourselves to dance and we feel old and decrepit.”

Even digital natives struggle sometimes: “I already have nostalgia for a simpler past, even though I’m 23,” says Maia. “It’s exciting but it does put so much pressure on a normal individual to be an entrepreneur to advertise their own personal brand.”

Journalists, regrettably, no longer have the power they once did. What matters these days is social media. The A&R (artists and repertoire) people at record companies who would once have hung out in basement clubs scouting for new talent now sit in meetings examining the data on artists’ social media performance.

Now that the whole world’s music is available all over the world at the click of a play button, there’s a greater diversity among top-selling artists.

People making videos of themselves performing or dancing to the song on TikTok helped propel it to the stratosphere. It has been streamed a billion times. Sethi now plays to packed venues in America and Europe; last year, he performed at Coachella, America’s Glastonbury. “Without digital technology I would be a south Asian indy musician, working on the fringes of Bollywood,” he says from his home in New York.

For musicians, it’s more ambiguous. Because the costs of making music are lower, anybody with ambition can have a go. Many more people, as a result, are getting into the music business. According to PPL, the organisation which distributes money to music performers and rights-holders, the number of registered artists has risen from 61,310, when the industry was at its nadir, to 165,039 last year.

That makes the business fiercely competitive. As Will Page, former chief economist at Spotify and author of Tarzan Economics, points out, around 100,000 tracks are being uploaded on to Spotify every day: that’s more than were released in an entire calendar year in the 1980s

That has cemented the power of the record companies. When the digital revolution started, it was widely expected that record labels would cease to exist, and be replaced by a model in which everybody promoted and distributed their own music. That’s not what has happened: because it’s so difficult to get noticed, embryonic stars need record labels to promote them.

A label invests in the production of the music, the styling of the band, video content, interviews, touring and the crucial business of getting a song on a streaming service’s playlist that suggests the song to listeners to suit their tastes. Artists that are signed with major labels get paid more, per stream, than those that aren’t.

Three quarters of streamed tracks have one of the major record labels behind them. And even though streaming is booming, it doesn’t contribute much to the incomes of the vast majority of artists.

Most artists stay hungry. A single stream will earn a musician anywhere between 0.1p and 2.4p. Crispin Hunt reckons that on average a million streams for a song — a wild ambition for most musicians — will, if you have to pay a cut to a record company, probably make you £1,000

If you’ve then got to pay your manager 20 per cent, and divide the rest between the four band members, “it barely pays for a Sainsbury’s shop. That’s why music is dominated by middle-class people called Crispin whose parents can afford to buy them an electric guitar and a laptop.”

For Christie Gardner, half of Lilo, a two-woman band, it helps planning gigs. “You can see where your listeners are and you can tell what they’re listening to. We make decisions about shows on that basis.” But for most bands, the economics of live performance are pretty grim.

Deathcrash’s manager Joe Taylor says that the band has been offered the opportunity of a European tour supporting a much bigger act. It would be good for their career but not their bank balance. The fees per show would be €200; once the costs of a sound engineer, a tour van, a driver, fuel, hotels and a carnet for importing musical instruments into the EU had been factored in, they would lose £15,000.

music has always been an uneconomic business, which people subsidise through other activities. The fiddler in the village pub probably worked in the fields in the daytime and played for money and fun in the evenings and at the weekend, rather as Ryder ran a juice bar and sang at weddings. These days, there is also the wafer-thin chance that they might end up being one of the 1,200 artists who make more than $1 million a year on Spotify

There are some signs that in the new musical economy, the balance of power between artists and the big record companies may have tipped slightly in the artists’ favour

the share of streaming revenues going to artists increased from 19.7 per cent to 23.3 per cent between 2012 and 2021 and that going to songwriters has risen from 8 per cent in 2008 to 15 per cent in 2021. “Outcomes for consumers, artists and songwriters,” it concludes, “are getting better.”

Most of the extra revenues generated by streaming are going to the top earners. But the stars are not the only ones benefiting. Between 2017 and 2022, the number of artists earning over $1 million on Spotify more than doubled, but so did the number earning over $10,000

more than two fifths of artists who release their own music aren’t expecting to make a full-time career. They’re in it for fun, for the love of it, or to be able to show their mum that they have released a song on Spotify.

It seems likely that the more music is being created, the greater the chance that wonderful tunes are being written, but it’s not necessarily the case. The best stuff might get buried under a mound of mediocrity.

Everywhere, new investment in green energy generation is being propelled by general concern for the climate, shifting corporate and household demand, the plunging prices for solar and batteries triggered by Chinese policy, and a combination of national and regional interventions

How different would we expect this data to look without the IRA?

The most useful overview of these modeling efforts that I have been able to find is by Bistline et al “Power sector impacts of the Inflation Reduction Act of 2022” in Environmental Research Letters November 2023. If anyone has a better source, please let me know.

The top panel shows the historical trajectory of US generating capacity from 1980 to 2021. The second half of the graphic shows how 11 different models predict that the US electricity system might be expected to develop up to 2035, with and without IRA.

all the models expect the trends of the 2010s to continue through to the 2030s which means that solar, wind and battery storage dominate America’s energy future. Even without the IRA, the low carbon share of electricity generation will likely rise to 50-55% by 2035. Bidenomics bumps that to 70-80 percent.

The question is: “How does the renewable surge of 2022-2024, compare to the model-based expectations, with and without the IRA?”

The answer is either, “so so”, or, more charitably, it is “too early to tell”. In broad terms the current rate of expansion is slightly above the rate the models predict without the provision of additional Bidenomics incentives. But what is also clear is that the current rate of expansion, is far short of the long-run pace that should be expected from the IRA

At this point, defenders of the IRA interject that the IRA has only just come into effect. Cash from the IRA is only beginning to flow. And in an environment of higher costs for renewable energy equipment and higher interest rates, cash matters.

As Yakov Feygin put it: “Maybe the pithiest way to put it is that there are pre-IRA trends and outside IRA trends, but IRA has served to rapidly compress the timeframes for installation in a lot of technologies. So five years has turned into two, for example.”

So, to judge the impact of the IRA to date, the real question is not what has been built in 2022 and 2023, but what is in the pipeline.

Advised by JP Morgan, sophisticated global players like Ørsted are optimizing their use of both the production and investment tax credits offered by the IRA to launch large new renewable schemes. Of course, correlation is not the same as causation

Where the IRA is perhaps doing its most important work may be in incentivizing the middle bracket of projects where green momentum is less certain.

According to Utility Drive: “The 10 largest U.S. developers plan to build 110,364 MW of new wind and solar projects over the next five years, according to S&P Global Market Intelligence, but the majority of these projects remain in early stages of development. Just 15% of planned wind and solar projects are under construction, and 13% are considered to be in advanced stages of development, … ”

The states that I have highlighted in red stand out either for their unusually low existing level of renewable power capacity or their lack of current momentum.

Along with Texas, the pipelines for the PJM, MISO and Southeast regions (which includes Florida) look particularly healthy.

The relatively modest California numbers should not be a surprise. As Yakov Feygin and others pointed out, what is needed in California is not more raw generating capacity, but more battery storage. And that is what we are seeing in the data.

The numbers would be even larger if it were not for the truly surreal logjam in California’s system for authorizing interconnections. According to Hamilton/Brookings data the volume of hybrid solar and batter capacity in the queue for approval is 6.5 times the capacity currently operating in the state. In other words there is an entire energy transition waiting to happen when the overloaded managerial processes of the system catch up

Texas’s less bureaucratic system seems to be one of its key advantages in the extremely rapid roll-out of solar.

though it may be true that globally speaking the United States as a whole is a laggard in renewable energy development,

If California (with an economy roughly comparable to that of Germany at current exchange rates) and Texas (with an economy roughly the size of Italy’s) were countries, they would be #3 and #5 in the world in solar capacity per capita.

the obvious question is, which are the laggards in the US energy system.

So there is a lot to get excited about, at, what we are learning to call, the “meso”-level of the economy (more on this in a future post).

What the state-level data reveal is that there are a significant number of large states in the USA where solar and wind energy have barely made any impact. Pennsylvania, for instance

The relative levels of sunshine between US states is irrelevant. As the global solar atlas shows, the entire United States has far better solar potential than North West Europe. If you can grow corn and tobbaco, you can do utility-scale solar. The fact that Arizona is not a solar giant is mind boggling.

Texas is both big and truly remarkable. California already is a world leader in renewable energy. Meanwhile, the majority of the US electricity system presents a very different picture. There is a huge distance to be traveled and the pace of solar build-out is unremarkable.

This is where national level incentives like the IRA must prove themselves

And these local battles in America matter. Given the extremely high per capita energy consumption in the USA, greening state-level energy systems is significant at the global level. It does not compare to the super-sized levels of emissions in China, but it matters.

Indonesia’s total installed electricity generating capacity is rated at 81 GW. As far as immediate impact on the global carbon balance is concerned, cleaning up the power systems of Pennsylvania and Illinois would make an even bigger impact.

A key test of Biden-era climate and industrial policy will be whether it can untie the local political economy of fossil fuels, which, across many regions of the United States still stands in the way of a green energy transition that now has all the force of economics and technological advantage on its side.
