Economics on the other hand cannot stand the scrutiny of the falsifiable hypothesis test since empirical results in economics are a function of the context. The short point is that economics cannot lay claim to the immutability, universality, precision and exactitude of physics. Take the recent financial crisis. It is not as if no one saw the pressures building up.
There were a respectable number of economists who warned of the perilous consequences of the build-up of global imbalances, said that this was simply unsustainable and predicted a currency collapse. In the event, we did have the system imploding but not as a currency collapse but as a melt down of the financial system.
