In Deep Survival, Who Lives, Who Dies, and Why, author Laurence Gonzales explains, โ€œThe events that we call โ€˜accidentsโ€™ do not just happen. There is not some vector of pain that causes them. People have to assemble the systems that make them happen. Even then, nothing may happen for a long time.โ€

In 1960, when MIT meteorologist Edward Lorenz was modeling weather systems, he discovered a tiny change in the initial state (1 part in 1,000), explains Gonzales, was enough to produce totally different weather patterns. It became known as the Butterfly Effect, โ€œthe notion that a butterfly stirring the air today in Peking can transform storm systems next month in New York,โ€ writes James Gleick in Chaos.

โ€œPeople routinely fail to realize that an accident not happening is no guarantee that it wonโ€™t happen,โ€ writes Gonzales. โ€œAs Scott Sagan puts it in The Limits of Safety, โ€˜things that have never happened before happen all the time.โ€™โ€ Words of wisdom to understand in times like these.

Action Line: The stock market is yet another manmade system, where accidents can and do happen without much warning at all. Be prepared.
