I reverse-engineer reproducible mental models (mathematics). A prominent transform has been misused for commercial purposes - religion. My job is to carefully regulate the release valves on highly compressed information infrastructures to assure the most stability during the implosion or paradigm shift as people realize that debt (debt/death/doubt) holds no value or substance, and therefore is an absurdity behind any currency. Today (since 1976) gold has been replaced for stabilizing the exchange rate of the US Dollar domestic and foreign with Special Drawing Rights (SDR's). This really marks the stage in removal from lawful money where humans became chattel.
Look up SDR or Special Drawing Rights (Paper Gold) for yourself; but my definition has been: "The measure of a society's conditioning to blindly endorse private credit from the local central bank."
