Law of Reversed Effort

When we call something a "law" of something, e.g. the "law" of gravity, it refers to something that is constant under normal conditions. Gravity is not the norm in the outer-hemisphere, or in a vacuum. But those aren't the norm. To call the idea of "reversed effort" a law is, in itself a paradox, since it cannot be proven as the norm when searching through the basic activities of humans every day life. Yet - it can easily be disproven through diligence. E.g. The more times I drive through Chicago, the easier the route will be to navigate. The law of reversed effort does not apply.
