That's simple, QE wasn't tested in any scientifically valid study. They made predictions of what QE may do, they enacted QE policies in an uncontrolled economy with no control group, and stuff happened. Afterwards they attempted to read the tea leaves and claim what precisely causes economic changes.
That isn't scientific at all. That also doesn't mean they were wrong, you can absolutely be right when you go off educated guesses or plain old intuition. My claim is that how economics is studied is not scientific in that it never has, and never can, follow the scientific method.
