I call it the conservation of effort. If you are able to save mental energy in one place, it necessarily has been spent in another.
That's not entirely true though. There are sometimes true wins in things like finding better perspectives, e.g. models that are both simpler and more accurate, good abstractions that separate concerns cleanly, stuff like that.
