TED
TED features talks and performances from the TED Conference, along with originals, podcasts, and other content on technology, entertainment, design, science, business, global issues, the arts, and related subjects.
Imagination Builds Shared Worlds When the Script Breaks
Professional child actor Suki Hillier argues that imagination is not an escape from reality but a way people build a shared world, onstage and beyond it. Drawing on her experience playing Matilda in *Matilda The Musical*, Hillier says the work depends on disciplined rehearsal, trust among performers and an audience willing to enter the story. When a mid-scene mishap disrupted a performance, she says, that collective imagination allowed the cast to adapt without breaking the world they had made.
Economic Inequality Is Driving Democratic Backsliding
Sally Kohn argues that democracy is endangered not only by attacks on voting rights but by an economic order that leaves too many people without security, opportunity or power. In her proposed “Democracy 3.0,” political inclusion must be matched by broader economic participation through measures such as higher wages, stronger unions, fairer wealth taxation and democratic business ownership. When democracy fails to improve material life, Kohn says, it creates the conditions in which authoritarianism can take hold.
Rapid Ketamine Relief Points to Brain Plasticity in Depression
Neuroscientist Lisa Monteggia argues that depression cannot be adequately explained as a serotonin shortage: SSRIs raise serotonin quickly, yet often take weeks to relieve symptoms, while ketamine can produce relief within hours through a different brain system. She says ketamine’s effects point instead to synaptic plasticity—the brain’s capacity to adapt—as a possible driver of antidepressant response, though the drug remains temporary, clinically limited and no replacement for first-line SSRI treatment.
Play Is a Survival Skill, Not a Reward for Productivity
Creative health scientist Katina Bajaj argues that adults have turned play into another optimized task—or abandoned it altogether—creating what she calls a “play deprivation crisis.” In her TED talk, she defines play as intrinsically motivated activity without a predetermined outcome, and contends that its uncertainty supports creativity, resilience and the capacity to adapt. Rather than scheduling more leisure, Bajaj urges people to preserve room for non-linear, imperfect and public forms of play in daily life.
Joy Is Inherited Through Shared Rituals, Places and Symbols
Artist Yinka Ilori argues that joy is less a private achievement than an inheritance carried through family rituals, places and gatherings. Drawing on his Nigerian parents’ life in London and Instagram responses about people’s earliest joyful memories, Ilori found that togetherness appeared in about 80 percent of accounts, ahead of nature, freedom, growth and stillness. He turns those memories into a visual language of shared symbols, intended to make transgenerational joy visible and transferable.
Objectivity Starts With the Story Behind a Belief
Joshua Johnson, the former NPR host and current actor/anchor for The Onion, argues that difficult conversations require objectivity rather than neutrality: keeping one’s judgments while temporarily setting aside the urge to rebut. His method is to ask how someone came to a belief, keep questions short, and follow the hesitations or admissions that break through prepared talking points. The goal is not agreement, Johnson says, but understanding the personal commitments an argument may conceal.
A Desktop Full of Files Cannot Guarantee Retrieval
Technologist and comedian Alan Resnick argues that “save it to your desktop” is more than a file-management instruction: it is a way to keep data, memories and physical objects visible rather than letting them disappear into the internet. In his TED talk, he proposes a desktop that holds everything—from family photos and poems to 3D scans of keepsakes—and rejects toolbars and conventional organization in favor of total proximity. The resulting crowded screen tests his claim that what remains in sight can also remain findable.
Cheap Solar Makes Deployment Speed the Decisive Climate Question
Environmental writer Bill McKibben argues that solar and wind have become the cheapest new sources of electricity, making a global shift away from fossil fuels economically likely. The climate question, he says, is whether deployment can move fast enough to limit further warming, rather than arriving decades after the damage is locked in. McKibben contends that permitting barriers, political resistance and fossil-fuel interests—not a lack of technology—now pose the central obstacle.
Reparative Work Should Honor the Person Harmed, Not Relieve Guilt
Gregg Ward, who says he caused his high-school sweetheart’s death in a car accident, argues that accountability for grave mistakes need not mean lifelong self-punishment. Drawing on decades of guilt and his work with others involved in accidental killings, he rejects self-forgiveness as an adequate answer and instead calls for reparative work directed toward the person harmed—their values, hopes and the difference they might have made.
Food Fortification Scales Only When Hardware Meets Enforcement
Felix Brooks-Church, co-founder of food-fortification enterprise Sanku, argues that “hidden hunger” can be addressed by adding essential nutrients to staple foods at the local mills that produce them. His model combines mill-compatible dosing machines, remote monitoring and local premix supply, but he says durable national scale ultimately depends on governments mandating fortification and enforcing standards through testing and inspection.
Russia’s Deteriorating Position Raises the Risk of Wider War
Political scientist Ian Bremmer argues that the Iran and Ukraine wars are both trapped without credible exits, but their risks differ sharply. He sees the Iran conflict as a costly, contained struggle over control of the Strait of Hormuz, while a weakening Russia may respond to setbacks in Ukraine by escalating pressure on NATO and civilian infrastructure. Bremmer’s central concern is that neither Washington nor Moscow has yet found a political settlement that leaders can accept.
Science Lessons Should Start With a Phenomenon, Not a Formula
Former NASA engineer and YouTube creator Mark Rober argues that science instruction should begin with a phenomenon students want to explain, rather than with formulas or vocabulary they are asked to absorb. His free Class CrunchLabs curriculum for grades three through eight uses short videos and low-cost experiments to prompt investigation, with teachers leading the discussion and sense-making. Rober’s claim is not that screens can replace teaching, but that a stronger initial hook can help teachers overcome what he sees as a motivation gap.
Peer Tutoring Builds the Human Skills AI Cannot Replicate
Matt Wu, who leads the nonprofit Schoolhouse, argues that AI can expand access to instruction but cannot replace the motivation, connection and sustained support students gain from another person. Schoolhouse pairs students around the world for free peer tutoring, with learners who master material able to become tutors themselves. Wu’s case is that this model builds academic skill while giving students practice in explaining, collaborating and helping one another learn.
Lead Exposure Affects One in Three Children Worldwide
Pure Earth’s Drew McCartor argues that lead poisoning remains a global public-health crisis, exposing more than a billion children and causing damage that cannot be reversed once it reaches a developing brain. His proposed response is straightforward: governments should measure children’s exposure, identify the main local sources, then regulate, enforce and clean them up. He points to Georgia, where action on lead-contaminated spices cut levels in the hardest-hit regions by 75 percent, as evidence that the model can work.
Agency Lies in Choosing the Next Track
Musician ELEW argues that life resembles DJing in “Club Reality”: disruptions cannot be prevented, but people remain responsible for choosing what comes next. Drawing on his move from jazz piano to DJing, he says the work is less about technical virtuosity than preparation, empathy and reading the room rather than imposing a preselected plan. He extends the metaphor to mental health, arguing that choices shape the atmosphere of one’s mind even when circumstances do not cooperate.
Political Disengagement Cedes Power Over Daily Life
Katie Paris argues that opting out of politics does not remove politics from a person’s life; it cedes power over decisions that shape it. With anti-career coach Danielle Roberts, she makes the case that civic participation begins in local institutions and trusted relationships, while Roberts argues that time, rest, joy and community are necessary to sustain that engagement.
Pediatric Care Must Make Room for a Child’s Life
James G. Robinson recounts his son Nadav’s five-year life with heterotaxy and a single-ventricle heart, arguing that medical care had to serve more than his circulation. Surgeries and emergency interventions kept Nadav alive, but Robinson and his wife, Tali, insisted on making room for travel, family life and ordinary childhood experiences even amid grave risk. A rare genetic explanation for Nadav’s condition did not make him, in Robinson’s account, a life that should have been avoided.
Leaders Cannot Control Change, but They Can Shape Belief
Workplace culture expert Jessica Kriegel argues that leaders undermine adaptability when they try to control people, processes and the narrative around difficult decisions. In this TED talk, she makes the case for “surrender”: accepting what leaders cannot dictate while shaping their own conduct and the experiences that influence employees’ beliefs. Her examples—from early disclosure of a planned layoff to a factory manager removing reserved parking—frame trust, rather than compliance, as the basis for change.
GLP-1 Drugs May Quiet Craving Beyond Food
Physician Dhruv Khullar argues in a TED talk that GLP-1 drugs such as Ozempic may prove significant not only as diabetes and obesity medications, but as possible treatments for addiction. Drawing on patient experience, emerging clinical research and animal studies, he says the drugs appear to quiet craving by acting on reward and withdrawal pathways in the brain. Khullar is careful not to cast them as a cure, but as a potential biological tool for moderation that could give some patients more room to choose.
Fast Vaccine Science Still Fails Without Public Trust
Immunologist Kizzmekia Corbett, who helped develop the first COVID-19 vaccine to enter clinical trials, argues in a TED talk that vaccine readiness depends as much on public trust as on scientific speed. She says scientists must treat the “vaccine inquisitive” — people with doubts, misinformation or fears — as an audience owed serious answers, not contempt. In her account, the next pandemic will test whether researchers can communicate uncertainty and risk as carefully as they design vaccines.
Physical Media Makes Art Harder to Erase
Music professor Tom Rizzuto argues in a TEDx talk that streaming has made media instantly available while weakening the public’s ability to possess and preserve it. Using Soviet “bone music” and the survival of Nosferatu as examples, he makes the case that physical copies matter not because they are nostalgic, but because they are harder for governments, courts or platforms to erase.
Americans Are More Ready for Democratic Reform Than Their Pessimism Suggests
Pew Research Center president Michael Dimock argues that American democracy was never meant to be a finished system, but an unfinished project requiring each generation to repair and adapt it. In a TED talk, he says Pew’s data show a public caught in polarization, civic disconnection and distrust of government, yet also more open to major democratic reform than its pessimism suggests.
Communication Style Tags Can Reduce Workplace Miscommunication
In a TED talk, leadership expert Melissa M. Mikus argues that much workplace friction is not caused by bad intent or personality conflict, but by missing information about how colleagues communicate and work best. Her proposed remedy is a “communication style tag”: a short, visible note in places such as email signatures, profiles or internal directories that states a person’s preferred channels, context needs and working norms before miscommunication turns into wasted time.
Teen Mental Health Is Not Primarily a Social Media Crisis
Developmental psychologist Candice Odgers argues in a TED talk that the dominant story about teenagers and technology is overstated: smartphones and social media are not the main explanation for youth distress. She says decades of data show a more mixed picture, with some teen risks at historic lows and mental health shaped more by adult distress, family conflict, school pressure and unsafe environments. Her warning is that social media bans may satisfy adults while diverting money and attention from counselors, teachers, safer spaces, digital mental health services and stronger regulation of tech companies.
