What to trust in a “post-truth” world | Alex Edmans

Only if you are truly open to the possibility of being wrong can you ever learn, says researcher Alex Edmans. In an insightful talk, he explores how confirmation bias — the tendency to only accept information that supports your personal beliefs — can lead you astray on social media, in politics and beyond, and offers three practical tools for finding evidence you can actually trust. (Hint: appoint someone to be the devil’s advocate in your life.)

The global goals we’ve made progress on — and the ones we haven’t | Michael Green

“We are living in a world that is tantalizingly close to ensuring that no one need die of hunger or malaria or diarrhea,” says economist Michael Green. To help spur progress, back in 2015 the United Nations drew up a set of 17 goals around important factors like health, education and equality. In this data-packed talk, Green shares his analysis on the steps each country has (or hasn’t) made toward these Sustainable Development Goals — and offers new ideas on what needs to change so we can achieve them.

How tech companies deceive you into giving up your data and privacy | Finn Lützow-Holm Myrstad

Have you ever actually read the terms and conditions for the apps you use? Finn Lützow-Holm Myrstad and his team at the Norwegian Consumer Council have, and it took them nearly a day and a half to read the terms of all the apps on an average phone. In a talk about the alarming ways tech companies deceive their users, Myrstad shares insights about the personal information you’ve agreed to let companies collect — and how they use your data at a scale you could never imagine.

The simple genius of a good graphic | Tommy McCall

In a talk that’s part history lesson, part love letter to graphics, information designer Tommy McCall traces the centuries-long evolution of charts and diagrams — and shows how complex data can be sculpted into beautiful shapes. “Graphics that help us think faster, or see a book’s worth of information on a single page, are the key to unlocking new discoveries,” McCall says.

Let’s launch a satellite to track a threatening greenhouse gas | Fred Krupp

When we talk about greenhouse gases, carbon dioxide gets the most attention — but methane, which often escapes unseen from pipes and wells, has a far greater immediate impact on global warming. Environmentalist Fred Krupp has an idea to fix the problem: launch a satellite that tracks global methane emissions, and openly share the data it collects with the public. Learn more about how simple fixes to cut down on this invisible pollutant can help us put the brakes on climate change. (This ambitious plan is one of the first ideas of The Audacious Project, TED’s new initiative to inspire global change.)

How we study the microbes living in your gut | Dan Knights

There are about a hundred trillion microbes living inside your gut — protecting you from infection, aiding digestion and regulating your immune system. As our bodies have adapted to life in modern society, we’ve started to lose some of our normal microbes; at the same time, diseases linked to a loss of diversity in microbiome are skyrocketing in developed nations. Computational microbiologist Dan Knights shares some intriguing discoveries about the differences in the microbiomes of people in developing countries compared to the US, and how they might affect our health. Learn more about the world of microbes living inside you — and the work being done to create tools to restore and replenish them.

The rapid growth of the Chinese internet — and where it’s headed | Gary Liu

The Chinese internet has grown at a staggering pace — it now has more users than the combined populations of the US, UK, Russia, Germany, France and Canada. Even with its imperfections, the lives of once-forgotten populations have been irrevocably elevated because of it, says South China Morning Post CEO Gary Liu. In a fascinating talk, Liu details how the tech industry in China has developed — from the innovative, like AI-optimized train travel, to the dystopian, like a social credit rating that both rewards and restricts citizens.

What if we eliminated one of the world’s oldest diseases? | Caroline Harper

Thousands of years ago, ancient Nubians drew pictures on tomb walls of a terrible disease that turns the eyelids inside out and causes blindness. This disease, trachoma, is still a scourge in many parts of the world today — but it’s also completely preventable, says Caroline Harper. Armed with data from a global mapping project, Harper’s organization Sightsavers has a plan: to focus on countries where funding gaps stand in the way of eliminating the disease and ramp up efforts where the need is most severe. Learn more about their goal of consigning trachoma to the history books — and how you can help. (This ambitious plan is one of the first ideas of The Audacious Project, TED’s new initiative to inspire global change.)

The nightmare videos of childrens’ YouTube — and what’s wrong with the internet today | James Bridle

Writer and artist James Bridle uncovers a dark, strange corner of the internet, where unknown people or groups on YouTube hack the brains of young children in return for advertising revenue. From “surprise egg” reveals and the “Finger Family Song” to algorithmically created mashups of familiar cartoon characters in violent situations, these videos exploit and terrify young minds — and they tell us something about where our increasingly data-driven world is headed. “We need to stop thinking about technology as a solution to all of our problems, but think of it as a guide to what those problems actually are, so we can start thinking about them properly and start to address them,” Bridle says.
