Experimental psychologist Petter Johansson researches choice blindness -- a phenomenon where we convince ourselves that we're getting what we want, even when we're not. In an eye-opening talk, he shares experiments (designed in collaboration with magicians!) that aim to answer the question: Why do we do what we do? The findings have big implications for the nature of self-knowledge and how we react in the face of manipulation. You may not know yourself as well as you think you do.

Driving in Johannesburg one day, Tapiwa Chiwewe noticed an enormous cloud of air pollution hanging over the city. He was curious and concerned but not an environmental expert -- so he did some research and discovered that nearly 14 percent of all deaths worldwide in 2012 were caused by household and ambient air pollution. With this knowledge and an urge to do something about it, Chiwewe and his colleagues developed a platform that uncovers trends in pollution and helps city planners make better decisions. "Sometimes just one fresh perspective, one new skill set, can make the conditions right for something remarkable to happen," Chiwewe says. "But you need to be bold enough to try."

Very few of us hold jobs that line up directly with our past experiences or what we studied in college. Take TED Resident Jason Shen; he studied biology but later became a product manager at a tech company. In this quick, insightful talk about human potential, Shen shares some new thinking on how job seekers can make themselves more attractive -- and why employers should look for ability over credentials.

We often find ourselves stuck in narrow social circles with similar people. What habits confine us, and how can we break them? Organizational psychologist Tanya Menon considers how we can be more intentional about expanding our social universes -- and how it can lead to new ideas and opportunities.

What is it about unfairness? Whether it's not being invited to a friend's wedding or getting penalized for bad luck or an honest mistake, unfairness often makes us so upset that we can't think straight. And it's not just a personal issue -- it's also bad for business, says Marco Alverà. He explains how his company works to create a culture of fairness -- and how tapping into our innate sense of what's right and wrong makes for happier employees and better results.

"The only way we're going to make substantial progress on the challenging problems of our time is for business to drive the solutions," says social impact strategist Wendy Woods. In a data-packed talk, Woods shares a fresh way to assess the impact all parts of business can have on all parts of society, and then adjust them to not only do less harm but actually improve things. Learn more about how executives can move beyond corporate social responsibility to "total societal impact" -- for the benefit of both a company's bottom line and society at large.

We all share one planet -- we breathe the same air, drink the same water and depend on the same oceans, forests and biodiversity. Economist Naoko Ishii is on a mission to protect these shared resources, known as the global commons, that are vital for our survival. In an eye-opening talk about the wellness of the planet, Ishii outlines four economic systems we need to change to safeguard the global commons, making the case for a new kind of social contract with the earth.

What does it look like when someone in Sweden brushes their teeth or when someone in Rwanda makes their bed? Anna Rosling Rönnlund wants all of us to find out, so she sent photographers to 264 homes in 50 countries (and counting!) to document the stoves, bed, toilets, toys and more in households from every income bracket around the world. See how families live in Latvia or Burkina Faso or Peru as Rosling Rönnlund explains the power of data visualization to help us better understand the world.

When trying to come up with a new idea, we all have times when we get stuck. But according to research by behavioral and learning scientist Marily Oppezzo, getting up and going for a walk might be all it takes to get your creative juices flowing. In this fun, fast talk, she explains how walking could help you get the most out of your next brainstorm.

Africa needs engineers, but its engineering students often end up working at auditing firms and banks. Why? Kamau Gachigi suspects it's because they don't have the spaces and materials needed to test their ideas and start businesses. To solve this problem, Gachigi started Gearbox, a makerspace and hardware accelerator that provides a rapid prototyping environment for both professionals and people with no formal engineering background. In this forward-thinking talk, he shares some of the extraordinary projects and innovations coming out of his Kenyan fab lab.
