A lot of the time you see a warning, in the subway, or in a movie theater, the main thrust of the warning will be to not panic if there is an emergency. To listen to directions. Now that's a waste. They could have given you information, but you can see their expectation that you're going to screw up.

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.

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.

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

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

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.

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.
