Cathy O'Neil: Weapons of math destruction 

13:18 minutes · Filmed Apr 2017 · Posted Aug 2017 · TED2017

Algorithms decide who gets a loan, who gets a job interview, who gets insurance and much more -- but they don't automatically make things fair. Mathematician and data scientist Cathy O'Neil coined a term for algorithms that are secret, important and harmful: "weapons of math destruction." Learn more about the hidden agendas behind the formulas.

Your cells are coated with sugars that store information and speak a secret language. What are they trying to tell us? Your blood type, for one -- and, maybe, that you have cancer. Chemical biologist Carolyn Bertozzi researches how sugars on cancerous cells interact with (and sometimes trick) your immune system. Learn more about how your body detects cancer, and how the latest cancer-fighting medicines could help your immune system beat the disease. Watch »

Should your driverless car kill you -- if it means sparing the lives of five pedestrians? In this useful primer on the moral dilemmas of driverless cars, Iyad Rahwan explores how new technology can challenge our own morality. In his lab, he asks real people to make the same moral judgments we're going to expect from our cars -- and his ongoing work reveals the ethical trade-offs we're willing (and not willing) to make. Watch »

Quote of the Week

Everyone uses algorithms. They just don't write them in code. Let me give you an example. I use an algorithm every day to make a meal for my family. The data I use is the ingredients in my kitchen, the time I have, the ambition I have. My definition of success is: a meal is successful if my kids eat vegetables. It's very different from if my youngest son were in charge. He'd say success is if he gets to eat lots of Nutella. But I get to choose success. I am in charge. My opinion matters. That's the first rule of algorithms. Algorithms are opinions embedded in code."
