There are about eight billion people on this planet. So if an event has a 1-in-a-million chance of occurring every day, it should happen to 8,000 people a day, or 2.9 million times a year, and maybe a quarter of a billion times during your lifetime. Even a 1-in-a-billion event will become the fate of hundreds of thousands of people during your lifetime. And given the media’s desire to promote shocking headlines, you will hear their names and see their faces.
The idea that incredible things happen because of boring statistics is important, because it’s true for terrible things too.
Think about 100-year events. One-hundred-year floods, hurricanes, earthquakes, financial crises, frauds, pandemics, political meltdowns, economic recessions, and so on endlessly. Lots of terrible things can be called “100-year events”.
A 100-year event doesn’t mean it happens every 100 years. It means there’s about a 1% chance of it occurring on any given year. That seems low. But when there are hundreds of different independent 100-year events, what are the odds that one of them will occur in a given year?
Pretty good.
