It's very analogous to trying to estimate a population mean when you have only a small sample. You get a large standard error. Right? Nevertheless, you don't find any chapters in the textbooks about the terrible things that happen when you're trying to estimate a population mean and have a small sample. Why not? Because there's no fancy name for that situation. You can't just say "estimating a population mean when you have a small sample." So I've constructed a fancy name, and now there'll have to be a chapter, and that name is "micronumerosity."
