The More we Know, The More we Know we Don't Know | Paniez Paykari | TEDxTehran 

The news media play a big role in our lives. The news media is how we keep an eye on the world and how we make sense of complicated issues and far away places. The news media are supposed to hold the powerful accountable, define our threats, and give us accurate information so we can form opinions and make decisions. But is the news media's number one priority to inform you? Or do they have another objective that we may not be aware? Veteran broadcast journalist Reza Sayah ​explains why the news media's objective isn't always to inform you with news you need, and why it's more important than ever to consume the news with a critical eye.
