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.

Well, there isn't any one profile of a survivor, but there are profiles. Depending on the disaster you have certain advantages and disadvantages just based on who you are. Women are more likely to survive hurricanes. In hurricanes the deaths come from floods and people driving through high water. That's much more likely to be a man who dies that way.

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.

The health of your family or your office or your city directly affects the health of it after. The better you are at handling high-stress situations with little information, those skills lead to resilience and the ability to recover afterward.

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.

People with military experience seem to do very well in these situations. They've been taught that they can control their destiny, which is half the battle. They also have some experience in getting out of bad situations even if just through training. They know they have to make a plan and follow it and execute it.

The evil genius of terrorism is that that maximizes unfamiliarity, imaginability, suffering, scale of destruction, unfairness. It's really important to understand why terrorism is so frightening because it is a psychological war and until you understand it and try to reduce the dread, until then you become like a force multiplier for the terrorists inadvertently because you'll tend to overreact to terrorist attacks because the dread factor is so high.
