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.

I can't tell you how many times I've been with very smart, knowledgeable Homeland Security experts who are essentially tasked with saving your life who do not trust you with information. They just don't. They kind of dismiss the media and the public in one fell swoop.

My anxiety about disasters is lower. The more you know, the less scary any of this stuff is. And that's my hope for the book. I want to get people's attention and tell them very valuable and ultimately hopeful information, and you find out nothing is as scary as your imagination.

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

By sort of combining the research of a lot of smart people, I came up with an equation for dread [dread=uncontrollability+unfamiliarity+imaginability+suffering+scale of destruction+unfairness]. The dread equation is a simplification, but it's a way to explain why we fear something so much when it is so unlikely. Part of it is the lack of control. That's why we're more scared of plane crashes than car crashes even though we know rationally which is more dangerous.

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.
