Women are far more likely to follow orders to evacuate, especially women with children. At the same time, women were much more likely to die during the South Asian tsunami. In some villages it was 3 to 1. And that was party because of the average strength it takes to hold onto something. Also it was cultural; women were less likely to know how to swim, as were children. So much of this is based on how we develop our own survival skills before something goes wrong: Even if nothing goes wrong, it might be good to know how to swim.

The public totally discounts low-probability high-consequence events. The individual says, it's not going to be this plane, this bus, this time.

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.

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.

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.

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.

People will help each other because there is a sense of camaraderie that springs up, which is a survival tactic. You help them because you know you might need their help later. And that is incredibly reassuring.
