Rare events … are NOT rare.
The modern internet has mated with the basic economics of risk and produced a frankensteinian beast. Suppose there is some awful thing that happens to people with a miniscule chance – say, once every 10 million times. It can be a car spontaneously combusting, the earth swallowing you up whole, or some awful disease striking you.
This is a rare event, and upon seeing it happen to someone your heart would break and your mind would shutter. However, in a huge world of 7 billion+ people, these miniscule events would actually happen quite regularly. In fact, we would expect to see these “rare” one-in-ten million events strike 700 times (per year, assuming an annual risk), or twice per day. With a good enough internet connection and decent enough access to modern cell phones, these twice per day awful events would hit our collective 7 billion phones quite regularly, leading everyone to think that these super-rare and horrible events are actually quite common. Where people go once they make that observation is a story for another day of course.
