Having spent years working in engineering (in addition to having lived most of my life in old houses and apartments), I have encountered some really, really stupid systems and solutions.
But even though these systems are dumb now, they tend to have a coherent internal logic, or at least did when they were new.
Often, that logic doesn’t apply anymore. Everything around that system has changed, and it is now obsolete. Anyone with a drawer full of orphaned power cords knows this one.
Other times, a system appears obsolete but isn’t. Japan’s tsunami stones were considered by some to be a relic of a past age—we can hold back the sea with technology!—but as we were sadly reminded in 2011, their advice remains sound.
When you come across something, a system, a tradition, a label or a warning, that makes no sense, before you dismiss it, change it, or rip it out completely, take a minute to consider:
What are the circumstances under which this would be a rational system?
Do these circumstances still apply?
