Aah, economy on HN… : ready, fight! More seriously, as Einstein put it quite briefly, economy is not a science because it is not testable. I would even add, following some philosopher's wisdom, that behind all those pretty theories you can sense their authors' fears and desires (plus some coherence and maybe even some stats…).

Economic theories cannot be tested, but there is definitely merit in historical evaluation of policies implemented.

Agreed, but precisely only through the mirror of our own desires and fears :)
