Reducing the visibility of polarizing content in social media feeds can measurably lower partisan animosity. To come up with this finding, my colleagues and I developed a method that let us alter the ranking of people’s feeds, previously something only the social media companies could do. Re-ranking social media feeds to reduce exposure to posts expressing anti-democratic attitudes and partisan animosity affected people’s emotions and their views of people with opposing political views. I’m a computer scientist who studies social computing, artificial intelligence, and the web. Because only social media platforms can modify their algorithms, we developed and relea…

Three months ago, I fired up ChatGPT and asked it to design a highly aggressive, short-term investment portfolio, selecting five stocks that were most likely to make me fabulously wealthy in six month’s time. Then, I threw good sense to the wind, transferred $500 of my actual money into a Robinhood account, and bought the stocks that ChatGPT had pitched. Since then, it’s been a wild ride. My portfolio has flown to new heights, giving me serious FOMO about the fact that I didn’t put all my money into ChatGPT’s picks. Then, it singed its wings, falling Icarus-style to lows that had me almost ready to bail on the whole thing and redirect the charred rema…

Five years ago, an algorithm decided whether your résumé ever reached a recruiter. Now, it might be the one asking you the questions. It can feel unsettling to imagine a machine assessing not just what you say, but how you say it: tone, cadence, word choice, even microexpressions. These patterns feed models that generate a “fit” score, determining whether you ever reach a human being. Agentic AI allows what appears to be a genuine two-way conversation, simulating a first-round interview more realistically than the one-way video prompts of the past. Companies are drawn to it for clear reasons: speed, consistency, and scale. But that efficiency comes with trade…

Massachusetts’ highest court heard oral arguments Friday in the state’s lawsuit arguing that Meta designed features on Facebook and Instagram to make them addictive to young users. The lawsuit, filed in 2024 by Attorney General Andrea Campbell, alleges that Meta did this to make a profit and that its actions affected hundreds of thousands of teenagers in Massachusetts who use the social media platforms. “We are making claims based only on the tools that Meta has developed because its own research shows they encourage addiction to the platform in a variety of ways,” said State Solicitor David Kravitz, adding that the state’s claim has nothing to do the company’s al…

After Joey Zwillinger stepped down as CEO of Allbirds in March 2024, he took three months off—mainly because his wife Liz said she’d divorce him if he jumped into another venture. He had run the sustainable shoe company for 10 years while the couple raised their three young children. “It took a real toll on the family,” Liz says. (“I would say it developed character in our family,” Zwillinger counters.) Before long, he was itching to start a new project, an ambition he shyly expressed to his wife. “It was really hard to want to sign up for something like that all over again,” Liz says. But this time, he cofounded the venture with Liz. It’s also a bold piv…

If you’re searching for a new snack that’s heavy on flavor but manages to skip the unhealthy additives, you’re in luck. There’s a new one called Ragerz from Good Eat’n, NBA star Chris Paul’s snack brand, in partnership with the WNBA’s Paige Bueckers. And it sounds like a slam dunk. For starters, the snack—which is a bit like a healthier take on Takis—is focused on delivering a fierce flavor without the junk. It comes in Chili Lime and Sweet Chili Crunch flavors that, Bueckers tells Fast Company, do not miss the mark (hoop?). The snack “isn’t asking people to give up flavor to feel better about what they’re eating,” she says, adding that with Ragerz, “you ca…

OpenAI said Tuesday it has picked Slack CEO Denise Dresser as its first chief of revenue, a message to wary investors that the ChatGPT maker is serious about making a profit from its artificial intelligence technology. OpenAI said Dresser will oversee global revenue strategy and “help more businesses put AI to work in their day-to-day operations.” Dresser had already spent more than a decade at Salesforce when the software pioneer announced in 2020 it was buying work-chatting service Slack for $27.7 billion. She helped integrate Slack into the software company before Salesforce CEO Marc Benioff picked her as CEO in 2023. Salesforce said in a statement that it …

A headline catches your eye: A company you admire, known for its market performance and strong culture, is embroiled in a massive scandal. It causes reputational harm, profitability tanks, and customers notice. The details feel depressingly familiar—enough to fill books (most recently The Dark Pattern). With postmortems pointing to “culture problems,” your instinct might be to double-check your own organization’s cultural health. So, you pull up last year’s employee engagement survey: 85% of employees feel comfortable raising concerns, and 90% believe leadership demonstrates ethical behavior. The numbers are reassuring. But the company you’ve read about probably had s…

Christmas is coming, and our bank accounts are getting, well, obliterated. But luckily, it’s no longer just your quirky aunt who appreciates a good secondhand store: Shopping for gently used items, especially during the holidays, is now on trend. And if you get on board, you might be able to save a bundle by swapping your mall run for a day of thrifting. In recent years, “Thriftmas”—or shopping for Christmas gifts at stores like Good Will, The Salvation Army, Savers, and online platforms that sell used items—has been creeping into the mainstream. And this year is no different. According to global data from online store ThredUp, in 2025, shoppers plan to dedicate near…

The rapid growth of data centers during the AI boom has been a dominating narrative of 2025—and, in many instances, not a popular one. Across the country, communities have pushed back against data centers planned for their cities and states. Some have even turned to online petition sites to raise awareness and voice collective opposition to data center projects in their communities. One such site, the popular platform Change.org, says it has seen a significant spike data center-related petitions in recent months. Change.org saw at least 113 petitions that mentioned data centers in 2025, the platform shared with Fast Company, totaling around 50,000 signature…

It’s beginning to look a lot like Christmas for the stock market, which may be headed for a “Santa Claus Rally,” according to analysts, including those at Goldman Sachs and Citadel Securities. “Barring any major shocks, it will be hard to fight the overwhelmingly positive seasonal period we are entering and the cleaner positioning set-up,” Goldman Sachs Group Inc.’s trading desk team said in a client note, as reported by Bloomberg. “While we don’t necessarily see a dramatic rally, we do think there is room to go up from here into year end.” Scott Rubner of Citadel Securities agreed, noting: “Following a year of strong portfolio returns and record household wealth,…

To quote Vince Vaughn in Four Christmases: “You can’t spell ‘families’ without ‘lies.’” That’s a cynical view, for sure, but when it comes to talking about one particular thing around the family dinner table at the holidays, it might be especially true. That thing? Work. According to a recent survey, young people are seriously bending the truth when it comes to talking to family members about their professional lives. The survey of 2,000 young U.S. adults (ages 21 to 35) from the digital skills course provider Elvtr found that a third have bailed on family events simply to avoid conversations about their jobs or career progress. Even more say they have stret…

The best-selling video game console this Black Friday was the PlayStation 5. That surprised no one. The number-two spot went to the Nintendo Switch 2. Again, that was expected. But the bronze position wasn’t held by Microsoft’s Xbox, as you might suppose. Instead, it was claimed by the Nex Playground, a small gaming system that almost no one had heard of two years ago. The Playground has since grown into one of 2025’s hottest gifts. In 2023, just 5,000 units of the controller-free small cube were sold. In 2024, that number spiked to 150,000. This year, the company is on track to sell 600,000 units. While it has a loyal (and growing) fan base, there are still …

In the 1966 film Fantastic Voyage, a spacecraft and its crew are shrunk to microscopic size and injected into the body of an injured astronaut to remove a life-threatening blood clot from his brain. The Academy Award-winning movie—later developed into a novel by Isaac Asimov—seemed like pure fantasy at the time. However, it anticipated what could be the next revolution in medicine: the idea that ever-smaller and more sophisticated sensors are about to enter our bodies, connecting human beings to the internet. This “internet of beings” could be the third and ultimate phase of the internet’s evolution. After linking computers in the first phase and everyday objects in t…

In a record weird year for the economy, the price of silver is the latest thing to behave strangely. The price of the second fiddle precious metal has soared over the last month, hitting record highs and outpacing the growth of gold. After hovering between $15 and $25 an ounce for much of the last decade, the price of silver topped $40 an ounce this fall before spiking to a record high of $82 at the end of December. After topping $80 on Monday, silver fell back closer to $70 an ounce – still more than double what the metal was worth only a year ago. Precious metals like silver tend to do well in times of economic uncertainty and 2025 has fit that bill and then som…

SoftBank Group will acquire digital infrastructure investor DigitalBridge Group in a deal valued at $4 billion, the companies said on Monday, as the Japanese investment firm looks to deepen its AI-related portfolio. The acquisition would expand SoftBank’s exposure to digital infrastructure as the Japanese conglomerate is positioning its portfolio to focus on artificial intelligence. DigitalBridge shares rose about 9.7% to $15.27 on Monday, following a 45% rise earlier this month after Bloomberg News first reported the acquisition talks. The $16 per share offer represents a 15% premium over DigitalBridge’s closing price on Friday and values the company at $2.92…

Lululemon Athletica‘s founder Chip Wilson said on Monday he had launched a proxy fight by nominating three independent directors to the company’s board, just over two weeks after the apparel maker announced the exit of CEO Calvin McDonald without a clear successor. Lululemon shares have shed nearly half their value this year as the company struggles to find its footing with younger and affluent shoppers, while battling stiff competition from fast-growing newer rivals such as Alo Yoga and Vuori, as well as pressure from activist investor Elliott Management. Wilson has nominated three director candidates to Lululemon’s board, including former On Running co-CEO Marc …

The start of a new year usually brings new motivation to achieve goals like eating healthier or finally cleaning your basement. Many resolutions also focus on financial goals, such as paying off credit card debt, saving for a new house, or simply getting more educated about money. “New Year’s is a really good time to review and realign your financial goals overall,” said Erica Grundza, certified financial planner at Betterment, an investing and savings app. When building your goals for 2026, Grundza recommends focusing less on the past and more on an optimistic, yet realistic, vision for the future. She recommends that you focus on reestablishing the “why” behind …

Is cable television truly dead? The markets are about to test the hypothesis. Shares of Versant Media Group began trading on the Nasdaq Monday under the ticker symbol VSNT, effectively completing Versant’s spinoff from parent company Comcast Corporation. Versant comprises a bundle of cable television networks and similar digital businesses, with notable properties including MS NOW (formerly MSNBC), CNBC, USA Network, Golf Channel, Oxygen, E!, and SYFY. It also includes online platforms such as Fandango, Rotten Tomatoes, GolfNow, GolfPass, and SportsEngine. Peacock, the popular streaming service owned by NBCUniversal, will remain under the Comcast umbrell…

As today is the first Monday of 2026, Americans across the country are settling back into their everyday routines after the busy holiday season. But many are also recovering from the flu—or still suffering from it. Flu illnesses are surging across the country. According to the most recent data from the Centers for Disease Control and Prevention (CDC), positive influenza test results reached the highest levels of the season for the week ending December 27, 2025. The CDC publishes a weekly influenza surveillance report that details positive case counts, illness activity levels by state, and breakdowns of flu types. Due to the winter holidays, the CDC’s la…
