Complex adaptive systems (finance, economies, ecosystems) are inherently ungovernable by design. The “crisis managers” have no clue what they are mathematically/logically doing either; what they’re doing is much more the performance of shamanic rituals (pumping liquidity, making bold confidence-building statements while hoping the patient doesn’t die before morning). In the end rationality is a big illusion. Systems are driven by human psychology / irrationality (expectations, feelings) and thus manipulating psychology is the most direct lever available.
