Security

In the movie Fight Club, the main character works for a vehicle company and assesses the number of car accidents caused by faulty auto parts versus the cost of a recall and this determines whether the auto company authorizes a recall. If the cost is too high, they won't do it, and this applies to security measures. If the probability of a threat is low and the cost is high, then a threat will be ignored. This diagram is about the closest one on the internet that reflects the paradigm of impact versus cost. The biggest factor for me with security is a different paradigm: that of risk versus hassle. If a security measure takes up too much of my time I won't bother with it. I'd rather just not put risky information in any source than my own head if it will be too much of a hassle to secure. Ultimately simplicity is more important to me, so like a big company, the cost of security is too high.
