If there is a larger takeaway here perhaps it is about paths of least resistance, with regards to both the actual flow of water and design decisions. On the one hand, it is easy to blindly follow regional precedents and traditions with long histories (or grab whatever is handy at the hardware store). On the other hand, sometimes it makes sense to take a step back and decide consciously how to reveal (or conceal) a natural process.

“These objects are, it is true, among the humblest of creatures that are endowed with organic life… Here we catch the first kindling of that spark, which glows into so noble a flame in the Aristotles, the Newtons, and the Miltons of our heaven-gazing race.”
Rain chains are a beautiful and functional alternative to traditional, closed gutter downspouts. Guiding rain water visibly down chains or cups from the roof to the ground, rain chains transform a plain gutter downspout into a pleasing water feature. From the soft tinkling of individual droplets to the soothing rush of white water, they are a treat to listen to.
Rain chains (‘kusari doi’ in Japanese) in concept are not a new idea. For hundreds of years, the Japanese have used the roof of their homes to collect water, transporting it downward with chains and finally depositing the rain water into large barrels for household water usage. Japanese temples often incorporate quite ornate and large rain chains into their design.
Sometimes there’s a Heuristic That Almost Always Works, like “this technology won’t change everything” or “there won’t be a hurricane tomorrow”.
And sometimes the rare exceptions are so important to spot that we charge experts with the task. But the heuristics are so hard to beat that the experts themselves might be tempted to secretly rely on them, while publicly pretending to use more subtle forms of expertise.
…Maybe this is because the experts are stupid and lazy. Or maybe it’s social pressure: failure because you didn’t follow a well-known heuristic that even a rock can get right is more humiliating than failure because you didn’t predict a subtle phenomenon that nobody else predicted either. Or maybe it’s because false positives are more common (albeit less important) than false negatives, and so over any “reasonable” timescale the people who never give false positives look more accurate and get selected for.
