I hate to nit-pick such an otherwise excellent article, but this is , unfortunately, an extremely misleading statement as read.
There is nothing in the Austrian methodology [nor in any other school of economics for that matter], that can bear any resemblance to the methodology of the physical sciences [i.e physics chemistry etc.], which use the only truly scientific methodologies that I am aware of.
Economics is a social science, not a physical science like, for example, physics or chemistry.
All Austrian economic insights are supposed to be derived from the consistent application, to preceding economic events, of logic [i.e. ratiocination and deductive reasoning], in retrospect, after the fact; and that post-event reasoning always starts from the assumption that all individuals are both unique, and have unique [and constantly changing/evolving] value systems.
Given the fact that all individuals are unique, what Von Mises himself called " methodological individualism" [ and the _true_ bedrock of all Austrian theory, and the starting assumption from which every other Austrian theory always proceeds], in no way can Austrian Economic theory therefor be reliably used to predict future economic events, such as the collapse of the $ US or Euro, or the collapse of a nation/state,or any other economic event, in any manner comparable to what can be quite reliably and accurately predicted in the physical sciences, where molecules etc. can be repeatedly experimented on in completely controlled laboratory environments, in order to reach conclusions about the way those molecules will behave in the future when subjected to the exact same conditions.
What About the Austrian Business Cycle Theory, Isn't That Predictive?
Although , as I would be the first to admit, there definitely is a business cycle, as the Austrians have repeatedly demonstrated, given the realities of human action, unlike the physical sciences, there is simply no way to know in advance at what stage of the business cycle we ever really are, or for how long a boom, a recession or a depression might conceivably last. There are simply too many known and unknown human action variables that can never be reliably measured [even if known], let alone accurately predicted.
At best, using Austrian theory at any point in a recession, or in a boom period, we can make educated guesses about what caused the present state, what might end it, and what might be next, but since all knowledge is finite, it is impossible to know with absolute certainty what is just over the horizon. It could be a depression, it could be a recovery, it could be something else- there is no way to know in advance using any supposedly "scientific", "predictive" properties of economic theory.
Summary: Austrian Business Cycle Theory can be very useful in trying to determine, after the fact, what might have caused an economic climate/event/scenario, but it has, no differently from any other school of economics , absolutely no use as a predictive tool that can accurately forecast future economic events, climates or scenarios.
As Always,The Economic Future Remains Unknown, and Unknowable
The US nation state might collapse next week, or it could stagger on for another 50-100 years , nobody knows for sure - the exact same thing can be said about its fiat currency [or that of any other nation]; the $US could fold soon, or it might recover and hang around for a lot longer - no one can be certain, despite what many claim _must_ happen, based on their understanding of Austrian theory,[ which I would suggest, is a simple misunderstanding].
Your [Free!] Financial Safety Services Summary:
SAVERS BEWARE! Do not believe any "investment professional" who attempts to "blind you with science" with his/her assumptions and predictions about the future performance of any investment he/she sells and whose results have been derived from graphics [charts etc.], or who claims that economics , whether it be Classical, Keynesian, Austrian, or something else entirely, is based on scientific principle , and that therefor, his/her predictions about the future are reliable .
Instead , start to construct a long term savings plan for your savings that is mostly immune to the unpredictable ups and downs of booms, recessions, depressions etc.
