Now more than ever, it's important to look boldly at the reality of race and gender bias -- and understand how the two can combine to create even more harm. Kimberlé Crenshaw uses the term "intersectionality" to describe this phenomenon; as she says, if you're standing in the path of multiple forms of exclusion, you're likely to get hit by both. In this moving talk, she calls on us to bear witness to this reality and speak up for victims of prejudice.
Women's equality won't just happen -- not unless more women are put in positions of power, says Sandi Toksvig. In a disarmingly hilarious talk, Toksvig tells the story of how she helped start a new political party in Britain, the Women's Equality Party, with the express purpose of putting equality on the ballot. Now she hopes people around the world will copy her party's model and mobilize for equality.
Five years ago, TED Fellow Jennifer Brea became progressively ill with myalgic encephalomyelitis, commonly known as chronic fatigue syndrome, a debilitating illness that severely impairs normal activities and on bad days makes even the rustling of bed sheets unbearable. In this poignant talk, Brea describes the obstacles she's encountered in seeking treatment for her condition, whose root causes and physical effects we don't fully understand, as well as her mission to document through film the lives of patients that medicine struggles to treat.
Say hello to the decentralized economy -- the blockchain is about to change everything. In this lucid explainer of the complex (and confusing) technology, Bettina Warburg describes how the blockchain will eliminate the need for centralized institutions like banks or governments to facilitate trade, evolving age-old models of commerce and finance into something far more interesting: a distributed, transparent, autonomous system for exchanging value.

Before soldiers are sent into combat, they're trained on how to function in an immensely dangerous environment. But they also need training on how to return from the battlefield to civilian life, says psychologist Hector Garcia.

On February 10, 2015, Suzanne Barakat's brother Deah, her sister-in-law Yusor and Yusor's sister Razan were murdered by their neighbor in Chapel Hill, North Carolina. The perpetrator's story, that he killed them over a traffic dispute, went unquestioned by the media and police until Barakat spoke out at a press conference, calling the murders what they really were: hate crimes. As she reflects on how she and her family reclaimed control of their narrative, Barakat calls on us to speak up when we witness hateful bigotry and express our allyship with those who face discrimination.

In the face of artificial intelligence and machine learning, we need a new radical humanism, says Tim Leberecht. For the self-described "business romantic," this means designing organizations and workplaces that celebrate authenticity instead of efficiency and questions instead of answers. Leberecht proposes four (admittedly subjective) principles for building beautiful organizations.
Americanization and globalization have basically been the same thing for the last several generations. But the US's view of the world -- and the world's view of the US -- is changing. In a fast-paced tour of the current state of international politics, Ian Bremmer discusses the challenges of a world where no single country or alliance can meet the challenges of global leadership and asks if the US is ready to lead by example, not by force.

Mallory Freeman shows us how private sector companies can help make real progress on big problems -- from the refugee crisis to world hunger -- by donating untapped data and decision scientists. What might your company be able to contribute?
Why should a good education be exclusive to rich kids? Schools in low-income neighborhoods across the US, specifically in communities of color, lack resources that are standard at wealthier schools -- things like musical instruments, new books, healthy school lunches and soccer fields -- and this has a real impact on the potential of students. Kandice Sumner sees the disparity every day in her classroom in Boston. In this inspiring talk, she asks us to face facts -- and change them.
Define students by what they contribute, not what they lack -- especially those with difficult upbringings, says educator Victor Rios. Interweaved with his personal tale of perseverance as an inner-city youth, Rios identifies three straightforward strategies to shift attitudes in education and calls for fellow educators to see "at-risk" students as "at-promise" individuals brimming with resilience, character and grit.
The smartphone you use reflects more than just personal taste ... it could determine how closely you can be tracked, too. Privacy expert and TED Fellow Christopher Soghoian details a glaring difference between the encryption used on Apple and Android devices and urges us to pay attention to a growing digital security divide. "If the only people who can protect themselves from the gaze of the government are the rich and powerful, that's a problem," he says. "It's not just a cybersecurity problem -- it's a civil rights problem."
In a society obsessed with body image and marked by a fear of fat, Kelli Jean Drinkwater engages in radical body politics through art.

"Unapologetic fat bodies can blow people's minds," she says.

In this forward-thinking talk, preview exciting concepts like modular, detachable buses, flying taxis and networks of suspended magnetic pods that could help make the dream of a dynamic, driverless world into a reality.
How do you teach an entire country how to vote when no one has done it before? It's a huge challenge facing fledgling democracies around the world -- and one of the biggest problems turns out to be a lack of shared language. After all, if you can't describe something, you probably can't understand it. In this eye-opening talk, election expert Philippa Neave shares her experiences from the front lines of democracy -- and her solution to this unique language gap.
"For a long time, I lived for death," says Manwar Ali, a former radical jihadist who participated in violent, armed campaigns in the Middle East and Asia in the 1980s. In this moving talk, he reflects on his experience with radicalization and makes a powerful, direct appeal to anyone drawn to Islamist groups that claim violence and brutality are noble and virtuous: let go of anger and hatred, he says, and instead cultivate your heart to see goodness, beauty and truth in others.
Machine intelligence is here, and we're already using it to make subjective decisions. But the complex way AI grows and improves makes it hard to understand and even harder to control. In this cautionary talk, techno-sociologist Zeynep Tufekci explains how intelligent machines can fail in ways that don't fit human error patterns -- and in ways we won't expect or be prepared for. "We cannot outsource our responsibilities to machines," she says. "We must hold on ever tighter to human values and human ethics."
What if doctors could monitor patients at home with the same degree of accuracy they'd get during a stay at the hospital? Bioelectronics innovator Todd Coleman shares his quest to develop wearable, flexible electronic health monitoring patches that promise to revolutionize healthcare and make medicine less invasive.
Something profound is changing our concept of trust, says Rachel Botsman. While we used to place our trust in institutions like governments and banks, today we increasingly rely on others, often strangers, on platforms like Airbnb and Uber and through technologies like the blockchain. This new era of trust could bring with it a more transparent, inclusive and accountable society -- if we get it right. Who do you trust?
Trauma silences its victims, says creative arts therapist Melissa Walker, but art can help those suffering from the psychological wounds of war begin to open up and heal. In this inspiring talk, Walker describes how mask-making, in particular, allows afflicted servicemen and women reveal what haunts them -- and, finally, start to let it go.
Tango, waltz, foxtrot ... these classic ballroom dances quietly perpetuate an outdated idea: that the man always leads and the woman always follows.
