In the best case, the DSL or abstraction doesn't leak and the effect of the code matches the intent so that you don't need to peek under the hood to make sure it's doing what you want/think. In that (rare) case, cognitive load remains low because you can work close to the problem domain and stay there without worrying about the specifics of the underlying code.
