We don't talk about that at all as a country. I think that most people assume that there's nothing they could do if a nuclear bomb went off in their city. And that's just not true. Most people would survive most terrorist nuclear attacks because the bombs would likely be much smaller than those we were dealing with in the Cold War.

Most serious plane crashes are survivable. There's a sense that, 'Oh, if we go down, that's it, it's out of my hands.' And that's just statistically not true. I have more optimism and more faith that my own actions can make a difference.

You could reduce people's fears if you gave them some useful information before things went wrong. It's really important to create a sense of confidence in the public in their own abilities before a disaster because they're the only ones who are going to be there. No one's going to help you for at least 24 to 72 hours. So it would be good to know more about it.

Boredom is the specter that haunts children from kindergarten to graduation on every continent.

Citizens are not prepared for attacks because there is a bias against the public by nearly every expert and government official. In emergency preparedness, there is this belief that public will panic, that the public is not to be trusted, that there will be looting.

The one thread that was most surprising and most consistent was the lack of fear that people felt at the worst moment. They felt a lot of fear in early stages, when they're just realizing what's happening. But then things really seemed to be at their peak of terror, the fear went away. You can imagine why that's useful. At that moment your brain needs to focus all its attention on surviving, so people will feel a sense of calm as their brain tries to sort out a plan.

Most Korean parents saw themselves as coaches, while American parents tended to act more like cheerleaders.
