How good are you at making security trade-offs ?

Bruce Schneier released a great essay on the Psychology of Security exploring how psychology can help explain the difference between the feeling of security and the reality of security. Quote :

We make security trade-offs, large and small, every day. We make them when we decide to lock our doors in the morning, when we choose our driving route, and when we decide whether we’re going to pay for something via check, credit card, or cash. They’re often not the only factor in a decision, but they’re a contributing factor. And most of the time, we don’t even realize, it. We make security trade-offs intuitively. Most decisions are default decisions, and there have been many popular books that explore reaction, intuition, choice, and decision.

These intuitive choices are central to life on this planet. Every living thing makes security trade-offs, mostly as a species — evolving this way instead of that way — but also as individuals. Imagine a rabbit sitting in a field, eating clover. Suddenly, he spies a fox. He’s going to make a security trade-off: should I stay or should I flee? The rabbits that are good at making these trade-offs are going to live to reproduce, while the rabbits that are bad at it are going to get eaten or starve. This means that, as a successful species on the planet, humans should be really good at making security trade-offs.
