The laws of economics will never be fully understood, and for the sake of argument I would not consider it a "science," simply because it cannot always be explainable.
When considering Natural Sciences as an area of knowledge, one of the key elements that seems to stand out is the use of reason when conducting experiments or gathering data. The various processes that scientists go through to find evidence to support their theories (trial and error, systematic result collection, experimenting with a hypothesis etc.) all add a certain weight to their discoveries about a knowledge claim, often strengthening the argument for or against a certain aspect of the claim. One issue that arose while we were examining Human Sciences as areas of knowledge, on the other hand, was how experiments have a comparatively less prominent role. Though both AOKs are “Sciences” and experimentation is therefore a key element of both areas, one of the weaknesses with the Human Sciences is that, often, the scale of the experiment is much larger and cannot be held under controlled conditions as, fundamentally, all human sciences deal with the analysis of human and societal behavior.
