That seems like an understatement. If most of the things you check are not okay, something is very wrong.
Even if the system is 100% perfect, you can’t possibly know that before hand. You’d be an idiot not to check anything, and since everything is okay, all the effort ends up being spent on checking things that, retrospectively, turned out to be ok.
