Where Independence Genuinely Breaks Down

Treating everything as independent is its own mistake, and a costlier one.

Having learnt that a coin has no memory, it is tempting to apply the lesson everywhere and treat every event as a clean slate. That produces a different failure. Much of ordinary life is connected, and the connections are precisely what make bad outcomes arrive together rather than politely spaced out. The storm that damages one roof in a street damages many, because it is the same storm. The delay that strands one traveller strands the whole platform. The morning that runs late for you runs late for everyone using the same road, which is part of why it ran late at all.

This matters because our sense of how bad a bad day can get is usually built on the assumption of independence. If troubles arrived one at a time, spaced out, most households could absorb them. What actually happens is that they arrive in a bundle, because they share a cause. The car and the roof and the missed shift are not three separate rolls. They are one weather event wearing three costumes. Any preparation built on the idea that misfortunes politely queue is preparation for a world that does not exist.

So the discipline runs both ways. Ask of a pattern whether there is any channel linking the events, and be sceptical when there is none. But ask of a plan whether it quietly assumes that nothing bad will coincide with anything else bad, and be sceptical when it does. Independence is a strong claim, not a default, and it deserves the same suspicion in both directions.
