Knowing the calorie content of foods does not help people understand which foods are healthier, according to a study I recently coauthored in the Journal of Retailing. When study participants considered calorie information, they rated unhealthy food as less unhealthy and healthy food as less healthy. They were also less sure in their judgments. In other words, calorie labeling didn’t help participants judge foods more accurately. It made them second-guess themselves. Across nine experiments with more than 2,000 participants, my colleague and I tested how people use calorie information to evaluate food. For example, participants viewed food items that are generally…

When Calvin McDonald was appointed CEO of Lululemon in 2018, the activewear brand was a cult brand. But it had the potential to become a retail giant. Chip Wilson founded Lululemon in Vancouver in 1998 as a yoga brand. When he left the CEO role in 2005, the company was generating $80 million a year. In the decade that followed, Lululemon grew steadily, boosted by the broader athleisure trend. But it was McDonald—who previously spent five years delivering double-digit growth as CEO of Sephora Americas—who transformed Lululemon into one of the biggest clothing companies in the world. Over the course of his seven-year tenure, McDonald more than tripled the company’s…

Over the past two years, a troubling trend has started to take shape in the media; for a large majority of journalists, DEI framing became the default for covering Black businesses. What should be stories about innovation, resilience, market disruption, and leadership have increasingly been flattened into a single, repetitive narrative: DEI. Not the company’s business model. Not the founder’s vision or entrepreneur journey. Not the problem being solved or the customers being served. Just DEI. And it’s often framed through the lens of rollbacks, political backlash, or cultural controversy. This didn’t begin overnight, but in recent years and especially amid the po…

Getting an idea of how much a dental visit is going to cost can be difficult, even if it’s staring you straight in the mouth. One company hopes to change that, using artificial intelligence to give patients and dentists real-time cost estimates—all while the drills are still buzzing and fluoride is flowing. Overjet, a dental AI platform, just launched the Dental Clarity Network, a collaboration of dentists and health insurance providers that aims to give more clarity into dental billing. The first initiative of the Network is the deployment of ReviewPass, a program that helps deliver real-time cost estimates and insurance coverage information related to tons of dental…

Artificial intelligence is transforming how we cure disease, defend nations, and deliver goods. But the same technology driving this surge of innovation is also testing the limits of the system that supports it. Innovation is moving faster than infrastructure, and our energy strategy has to catch up. It’s time to manage energy as a strategic asset. While AI is fueling demand at historic levels, it also gives us the tools to use power more intelligently, stabilize the grid, and unlock capacity we already have. If we work together, AI can turn today’s energy challenge into tomorrow’s competitive advantage. INNOVATION IS OUTPACING THE GRID AI is reshaping the global …

The moment I rise in the morning, I check my phone. Bad habit, to be sure. But I know I’m not the only one. There is a message from an editor marked “urgent,” there is an email from the school reminding me it’s parent-visit morning, and a text from a fellow soccer mom making sure I remembered the time change for Sunday’s tournament. (I hadn’t). The day had barely started, and I already felt hopelessly behind. This is the reality for working parents everywhere. On any given day, we have many jobs: employee, caregiver, chauffeur, chef, boo-boo healer—and each has its own inbox. Once upon a time, we believed technology would make our lives easier. Instead, it taught us h…

Performance reviews are often arduous, but they don’t have to be. AI tools can enhance the process for both managers and employees, offering new possibilities for efficiency and fairness. From streamlining data analysis to eliminating bias, here’s how AI is transforming performance evaluations and employee development across various industries. AI Connects Dots for Comprehensive Reviews AI has significantly improved our performance review process by providing managers with a clearer, more comprehensive view of their teams. Previously, we had vast amounts of data buried across various productivity tools—including meeting notes, shared documents, messages, and task u…

When it’s time to face the day first thing in the morning, everybody needs information—about the weather, their calendar, and what’s going on. Most of us get all this information manually, building habits like listening to the radio, browsing various news and media apps, and checking schedules. But a storied few have personal assistants who will curate all of that, creating a highly personalized set of prioritized information. That, as far as I can tell, is exactly what ChatGPT Pulse is supposed to be: a digital assistant in the true sense of the word. Pulse is a new feature in ChatGPT that’s available initially only to ChatGPT Pro subscribers (that’s the $200 monthly…

When the camera was invented in 1826, many people thought painting would die. But it didn’t. Instead, painters found new ways to express themselves. Painters reinvented expressionism, impressionism, and abstract art. Monet, Munch, and later Picasso, all thrived after the camera arrived. When personal computers became common in the 1980s, there was fear that creative thinking would become less valuable. But computers opened the door to digital design, animation, and new forms of storytelling. Studios like Pixar, founded in 1986, showed how technology could help artists create worlds that were impossible before. When Photoshop launched in 1988, photographers worri…

A Florida man initially began using Google’s Gemini AI platform last August for assistance with typical queries. By early October, the chatbot had driven him to commit suicide, claims a lawsuit filed against the tech giant on Wednesday. The father of Jonathan Gavalas is suing Alphabet, Google’s parent company, for monetary and punitive damages after discovering troubling messages in the chat logs that the 36-year-old exchanged with Gemini 2.5 Pro, Google’s latest AI model at the time. In the span of less than two months, the chatbot took on an outsized role in Gavalas’ life by adding fuel to his already “clear signs of psychosis,” stoking a quasi-romantic relationship…

Business leaders are scrambling to understand the fast-moving world of artificial intelligence. But if companies are struggling to keep up, can today’s business schools really prepare students for a new landscape that’s unfolding in real time out in the real world? Stanford University thinks it might have the answer. At its Graduate School of Business, a new student-led initiative aims to arm students for a future where AI is upending in ways that are still unfolding. The program, called AI@GSB, includes hands-on workshops with new AI tools and a speaker series with industry experts. The school also introduced new courses around AI—including one called “AI for Hum…

Don’t beat yourself up if you do some serious damage on a cheese plate during holiday festivities this year: You just may do your future self a favor. A new study has found that eating nearly 2 ounces or more of high-fat cheese each day has been associated with a 16% lower risk of dementia, according to the study published this week in Neurology. Lest you think this is some sort of propaganda by Big Cheese, the study followed nearly 28,000 adults in Malmö, Sweden for roughly 25 years. The study’s findings indicate that Swedes who ate more cheese with a fat content exceeding 20%—which includes many varieties of cheddar, gouda, and blue cheese, among others—had a lo…

At risk of stating the obvious, farming is physically challenging work that takes a toll on the human body. Over the years, we have turned to various forms of technology to amplify the efforts of a single person, starting with a single plow behind a mule or ox, progressing to a motorized tractor, 700+ horsepower combine harvesters, and now robotic weeders and autonomous flying drones that handle a range of tasks. But what about the human body? Is it destined simply to be replaced by machines? The fact is that people remain a weak link in modern farming. According to some sources, agriculture is considered the most hazardous occupation globally. Work-related musculoske…

U.S. hospitals generate nearly six million tons of waste each year, and a single patient can be responsible for more than 30 pounds a day. Much of that waste comes from the operating room (OR), which accounts for up to a third of a hospital’s total output and is among the most expensive areas to manage. A large portion comes from single-use devices, packaging, and transport materials. These practices are often criticized, and not without reason. But in settings like transplantation, much of that waste is directly tied to protecting patients. I’m often asked, “Why not make devices reusable?” or “What about the environmental impact?” After years in the OR and workin…

The Fast Company Impact Council is an invitation-only membership community of leaders, experts, executives, and entrepreneurs who share their insights with our audience. Members pay annual dues for access to peer learning, thought leadership opportunities, events and more. Regardless of whether your company has a strict in-office policy or supports a flexible schedule, the reality is that office attendance is at its highest levels in five years, according to Bisnow. Nobody would argue the need for a healthy office, especially one with more people in it. And if you ask what makes a healthy office, most would say it is one that supports physical health and safet…

For 50 years, America’s generosity has been stuck in neutral with charitable giving frozen at 2.5% of GDP. But not because people stopped caring. In 2024, total giving hit record highs, and food banks saw donations surge as families faced delays in SNAP benefits. The heart is there. What’s missing is technology that turns generosity into lasting impact. We can’t solve today’s biggest problems, from food insecurity to climate change to health inequity, without unlocking the full potential of AI. For the first time, technology connects data across causes, predicts needs before they arise, and turns generosity into measurable progress. If generosity is the fuel, AI is th…

The Real ID requirement goes into effect today (Wednesday May 7, 2025). The deadline has been 20 years in the making, and its implementation today could cause some headaches—or at least some confusion—for those trying to fly domestically. Here’s what you need to know about today’s Real ID deadline and what it means for you. What is Real ID? A Real ID is the name given to an updated form of driver’s licenses and state IDs that have enhanced security measures. The federal government sets these standards, even though Real IDs are issued by individual states. From May 7, a Real ID will be required in most circumstances to board a domestic flight in America, ent…

In 2021, Prada created “Candy,” an influencer designed to sell perfume. With an appearance rendered using then-state-of-the-art tools, Candy’s not-quite-real vibe felt straight out of the Silicon (Uncanny) Valley. It was peppy, but cartoonlike, and it was hard to see how Candy could sell perfume it could never smell. Since then, technologies have greatly improved. A brand can now render any persona with a product, create movies with that model persona animated in a realistic way, and show them demonstrating products. By creating their own influencers, brands can keep their advertising budgets down and generate profits. It’s possible that the virtual influencers will …

We don’t talk enough about what doesn’t scale. Which is ironic, because we talk about scale constantly. Scale is the shorthand for success in just about every industry. If it can’t scale, is it even worth doing? That’s the kind of thinking that floods strategy decks, venture capitalist meetings, and quarterly reviews. But here’s the question I keep circling back to: Can it still matter if it doesn’t scale? Because I’ve seen real impact in spaces where scale wasn’t the point. And frankly, it wasn’t even possible. THE MYTH OF “MASS = MEANING” There’s a quiet arrogance baked into how we treat scale, as if the size of a thing is what determines its signific…
