Human Intelligence Sharply Declining
No, it's not just you — people really are less smart than they used to be.
As the Financial Times reports, assessments show that people across age groups are having trouble concentrating and losing reasoning, problem-solving, and information-processing skills — all facets of the hard-to-measure metric that "intelligence" is supposed to measure.
These results, the FT reports, are gleaned from benchmarking tests that track cognitive skills in teens and young adults. From the University of Michigan's Monitoring the Future study documenting concentration difficulties of 18-year-old Americans to the Programme for International Student Assessment (PISA) that measures the learning skills of 15-year-olds around the world, years of research suggest that young people are struggling with reduced attention spans and weakening critical thinking skills.
Though there has been a demonstrably steep decline in cognitive skills since the COVID-19 pandemic due to the educational disruption it presented, these trends have been in evidence since at least the mid-2010s, suggesting that whatever is going on runs much deeper and has lasted far longer than the pandemic.
Obviously, there's no single answer as to why people seem to be struggling with cognitive skills, but one key indicator is the sharp decline in reading and the world's changing relationship to the way we consume information and media. In 2022, for example, the National Endowment for the Arts found that just 37.6 percent of Americans said they'd read a novel or short story in the year prior — a share down from 41.5 percent in 2017 and 45.2 percent in 2012.
It would be easy enough to blame this decline on people reading less (and, presumably, scrolling online brainrot more). But according to 2023 results from the Organization for Economic Co-operation and Development, the same international consortium that puts out the PISA survey, 34 percent of adults in the United States scored at the lowest levels of numeracy, which essentially means that they lack the ability to work with numbers. A year prior, that share was just 29 percent.
Beyond changes in media consumption and the mediums in which we take it, it appears, as the FT notes, our relationship to information generally is shifting too. While there certainly are ways to use tech that don't cause harm to cognition, studies show that "screen time" as we know it today hurts verbal functioning in children and makes it harder for college-age adults to concentrate and retain information.
There isn't any reason to suggest that human intellect has been harmed, the publication counters — but in "both potential and execution," our intelligence is definitely on the downturn.

The Key to Better Sleep Is in Your Gut, Says Gastroenterologist
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Around 25 million U.S. adults suffer from insomnia. At the same time, more than 3.9 million Americans are taking probiotics, usually for gut health, according to the American Gastroenterological Association (AGA). And gut health could be the key to better sleep. A study published in the journal Engineering examined a specific probiotic strain called Lactobacillus helveticus CCFM1320. This probiotic produces a compound known as SAM (S-adenosylmethionine), which helps regulate the body's internal clock and supports the production of melatonin, a hormone that promotes sleep. The researchers found that this probiotic could significantly improve sleep quality. The Gut as a Second Brain Neuroscientist Dr. Chelsie Rohrscheib, the head of sleep at Wesper, a national home sleep disorder diagnostics company, told Newsweek: "The gut essentially acts as a secondary nervous system and creates and releases many crucial neurotransmitters, such as serotonin, which also help to regulate nervous system activity. "This allows for two-way communication between the gut and the brain, called the gut-brain axis. Healthy gut microbes are essential to keeping the gut healthy and functioning, and there is ample evidence that gut microbiota dysregulation can negatively impact the activity of the gut-brain axis. Because the brain is highly sensitive, this can lead to poor sleep quality." Stock image of a woman taking pills from her nightstand before bed.

To test the effectiveness of CCFM1320 in humans, scientists from Jiangnan University conducted a four-week study with 60 volunteers who experienced sleep difficulties. Participants were divided into two groups: one received the probiotic, while the other took a placebo. Results showed that those who consumed the probiotic had better sleep scores, lower levels of the stress hormone cortisol, and a healthier balance of gut bacteria. Additionally, the probiotic boosted the expression of genes involved in producing and utilizing SAM, a key factor in sleep and overall health. Strain-Specific Benefits Dr. Michel Bass, a board-certified gastroenterologist and the Founding Medical Director at Oshi Health in Philadelphia, Pennsylvania, emphasized the importance of strain specificity: "Not all probiotics are created equal. This study identified CCFM1320 as uniquely beneficial for sleep quality. This isn't a generic 'take-any-probiotic' situation—it's about strain-level specificity," Bass told Newsweek. "That's where a lot of public messaging needs to evolve. Just like different medications target different conditions, different strains do different things. And this one appears to enhance melatonin synthesis via SAM methylation—a novel pathway." Probiotic Supplements vs. Fermented Foods Stock image of an assortment of fresh vegetables and meats. Stock image of an assortment of fresh vegetables and meats. esilzengin/iStock / Getty Images Plus While fermented foods like yogurt, kimchi, and kefir are beneficial for general gut health, Bass explained that they may not provide targeted probiotic strains at therapeutic levels. "If someone wants to improve things like sleep quality or reduce stress hormones like cortisol, a strong, well-researched supplement—especially one with proven strains like CCFM1320—is usually more effective," he said. "That said, eating fermented foods is still a great daily habit and can complement targeted probiotic supplements." Jason Eastty, owner of Healthspan Longevity in Westborough, Massachusetts, and a nutrition specialist, added that overall good nutrition can combat poor sleep. "Having a nutrient deficiency—like low iron, magnesium, or vitamin D—can throw off your gut microbial balance, leading to poor sleep. Clinical trials have shown that correcting these deficiencies helps microbial diversity and improves sleep efficiency," Eastty said. He also emphasized that a whole-foods diet rich in fiber—from fruits, vegetables, legumes, nuts, seeds, and whole grains—is essential to feeding the "good" bacteria in your gut.

The Computer-Science Bubble Is Bursting
The job of the future might already be past its prime. For years, young people seeking a lucrative career were urged to go all in on computer science. From 2005 to 2023, the number of comp-sci majors in the United States quadrupled. All of which makes the latest batch of numbers so startling. This year, enrollment grew by only 0.2 percent nationally, and at many programs, it appears to already be in decline, according to interviews with professors and department chairs. At Stanford, widely considered one of the country's top programs, the number of comp-sci majors has stalled after years of blistering growth. Szymon Rusinkiewicz, the chair of Princeton's computer-science department, told me that, if current trends hold, the cohort of graduating comp-sci majors at Princeton is set to be 25 percent smaller in two years than it is today. The number of Duke students enrolled in introductory computer-science courses has dropped about 20 percent over the past year. But if the decline is surprising, the reason for it is fairly straightforward: Young people are responding to a grim job outlook for entry-level coders. In recent years, the tech industry has been roiled by layoffs and hiring freezes. The leading culprit for the slowdown is technology itself. Artificial intelligence has proved to be even more valuable as a writer of computer code than as a writer of words. This means it is ideally suited to replacing the very type of person who built it. A recent Pew study found that Americans think software engineers will be most affected by generative AI. Many young people aren't waiting to find out whether that's true. 'It's so counterintuitive,' Molly Kinder, a Brookings Institution fellow who studies AI's effect on the economy, told me. 'This was supposed to be the job of the future. The way to stay ahead of technology was to go to college and get coding skills.' But the days of 'Learn to code' might be coming to an end. If the numbers are any indication, we might have passed peak computer science. Chris Gropp, a doctoral student at the University of Tennessee at Knoxville, has spent eight months searching for a job. He triple-majored in computer science, math, and computational science at the Rose-Hulman Institute of Technology and has completed the coursework for a computer-science Ph.D. He would prefer to work instead of finishing his degree, but he has found it almost impossible to secure a job. He knows of only two people who recently pulled it off. One sent personalized cover letters for 40 different roles and set up meetings with people at the companies. The other submitted 600 applications. 'We're in an AI revolution, and I am a specialist in the kind of AI that we're doing the revolution with, and I can't find anything,' Gropp told me. 'I found myself a month or two ago considering, Do I just take a break from this thing that I've been training for for most of my life and go be an apprentice electrician? ' Gropp is contending with a weak job market for recent college graduates in general and the tech sector in particular. Although employment for 22-to-27-year-olds in other fields has grown slightly over the past three years, employment for computer-science and math jobs in that age group has fallen by 8 percent. Not long ago, graduates from top comp-sci programs—such as those at Stanford, UC Berkeley, and Carnegie Mellon—would have been fending off recruiters from Google and Amazon. Now, professors at those schools told me, their graduates are having to try much harder to find work. Gropp's dad, William Gropp, runs the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign. 'I can say, as the father of a computer-science master's degree holder with expertise in machine learning who is still looking for a job, that the industry is not what it used to be,' he told me. In the ultimate irony, candidates like Gropp might be unable to get jobs working on AI because AI itself is taking the jobs. 'We know AI is affecting jobs,' Rusinkiewicz, from Princeton, told me. 'It's making people more efficient at some or many aspects of their jobs, and therefore, perhaps companies feel they can get away with doing a bit less hiring.' Derek Thompson: Something alarming is happening to the job market The best evidence that artificial intelligence is displacing tech workers comes from the fact that the industry that has most thoroughly integrated AI is the one with such unusually high unemployment. Tech leaders have said publicly that they no longer need as many entry-level coders. Executives at Alphabet and Microsoft have said that AI writes or assists with writing upwards of 25 percent of their code. (Microsoft recently laid off 6,000 workers.) Anthropic's chief product officer recently told The New York Times that senior engineers are giving work to the company's chatbot instead of a low-level human employee. The company's CEO has warned that AI could replace half of all entry-level workers in the next five years. Kinder, the Brookings fellow, said she worries that companies soon will simply eliminate the entire bottom rung of the career ladder. The plight of the tech grads, she told me, could be a warning for all entry-level white-collar workers. Not everyone agrees that AI is causing the turbulence in the job market. The tech industry frequently goes through booms and busts. The biggest companies exploded in size when the economy was good. Now, with high interest rates and the specter of new tariffs, executives are likely holding off on expanding, and workers are reluctant to leave their job, says Zack Mabel, director of research at the Georgetown University Center on Education and the Workforce. Companies have an incentive to blame layoffs on AI instead of forces within their control, David Deming, an economics professor at Harvard, told me. 'Before we see big changes from AI in the labor market, companies have to internalize this new capability and change what they ask for. And that's the thing that I have not seen very much of,' he said. 'It could be AI, but we just don't know.' Enrollment in the computer-science major has historically fluctuated with the job market. When jobs are scarce, people choose to study something else. Eventually, there aren't enough computer-science graduates, salaries go up, and more people are drawn in. Prior declines have always rebounded to enrollment levels higher than where they started. (And some universities, such as the University of Chicago, still haven't seen any enrollment drops.) Sam Madden, a computer-science professor at MIT, told me that even if companies are employing generative AI, that will likely create more demand for software engineers, not less. Whether the past few years augur a temporary lull or an abrupt reordering of working life, economists suggest the same response for college students: Major in a subject that offers enduring, transferable skills. Believe it or not, that could be the liberal arts. Deming's research shows that male history and social-science majors end up out-earning their engineering and comp-sci counterparts in the long term, as they develop the soft skills that employers consistently seek out. 'It's actually quite risky to go to school to learn a trade or a particular skill, because you don't know what the future holds,' Deming told me. 'You need to try to think about acquiring a skill set that's going to be future-proof and last you for 45 years of working life.' Of course, when faced with enormous uncertainty, many young people take the opposite approach and pursue something with a sure path to immediate employment. The question of the day is how many of those paths AI will soon foreclose.

We Need to Invest in the Heartland
For too long, the national conversation about innovation, the future of higher education, and economic growth has been dominated by a handful of colleges and universities largely based in coastal power centers. In doing so, we've overlooked the rest of the country and have weakened the broader foundation of American capitalism and democracy. There is another path forward—and it runs through the heartland of America. Across the country, families, and employers are rethinking the value of a college degree. Meanwhile, the pace of technological change is accelerating—AI is transforming industries, new sectors are emerging, and the demand for skilled talent is shifting rapidly. This comes at a time when public trust in institutions is eroding, and millions of Americans are asking whether our systems still work for them. Whether America leads or lags in this new window of opportunity depends on how we respond. With bold leadership and deep partnerships between universities and the private sector, the heartland can become the driving force behind America's next wave of innovation, economic competitiveness, and shared prosperity. Businesses and philanthropists are uniquely positioned to scale this pivotal moment: one that calls for a new, more inclusive era of American innovation and entrepreneurial growth. In the Midwest, universities are working hand-in-hand with businesses—and proving that the innovation and growth of the future will not be confined to any one part of the country. This region is uniquely suited to lead the next wave of American renewal. It has what the moment demands: grit, talent, urgency, and values that anchor capitalism in real lives and impact. As a nation, we often overlook where some of the most consequential innovation is happening. While innovation breakthroughs are happening at an exciting pace in the heartland, venture capital dollars continue to concentrate in California, New York, and coastal cities. Moreover, research centers are partnering with hospitals and farms, and in classrooms from coast to coast students are working with local employers to move forward in areas like AI, energy, bioscience, and robotics. This is where innovation reaches scale and serves everyday people, and not just markets or valuations. The future of American prosperity will be shaped by whether states, the federal government, and individual donors continue to invest in public universities embedded in their communities—institutions that serve as launchpads for discovery, entrepreneurship, and upward mobility for millions of people. For more than 80 years, universities have partnered with government and industry to drive innovation, advance research, and develop a skilled workforce. For the United States to maintain its global leadership, it is important for these three sectors to renew and strengthen their collaboration in the face of emerging challenges and opportunities. Public institutions, in fact, enroll three-quarters of the roughly 19 million college students in the United States, according to the National Center for Education Statistics. More specifically, America's land-grant institutions, created by and for the people, are uniquely positioned to rewrite the value proposition for higher education for the next generation. Access and opportunity are at the core of our mission, calling us to do work that directly benefits the people we serve. We exist to make life better in the communities of which we are a part. At The Ohio State University, demand is soaring for affordable academic programs, deep partnerships with industry, and innovation-based education and research. It's why we launched the Center for Software Innovation and joined the NextGenAI consortium from OpenAI—bringing additional research grants, funding, and API access to AI-related campus work. But for partnerships like these to grow, we need a mindset shift—within universities and across business and philanthropy. Investors and employers must see the Midwest as a wellspring of ideas, talent, and leadership. More broadly, we must ensure research dollars and economic incentives reach every corner of America. These investments make the United States more resilient and competitive globally while unlocking a wider pool of ideas, perspectives, and solutions. When America invests in our universities, we invest in well-rounded citizens, building social mobility and stability, and research that literally saves lives. We know this from experience. One of us is a Navy airman turned university president. The other, a software entrepreneur turned university benefactor and investor. We've seen how cross-sector leadership can create durable, inclusive growth. But this work can't be piecemeal. We need a national rallying cry to drive how, where, and why we invest in America's future. That future can start in the heartland, if we recognize its potential and act accordingly. The heartland doesn't just hold the key to America's economic future—it holds the promise of a robust economy rooted in community, powered by purpose, and capable of restoring trust in systems meant to serve us all.
