The scientific establishment uses falsifiability the way postmodernists use deconstructionism: selectively, to tear down the ideas of their enemies but not to apply to their own ideas. The deconstructionist will happily deconstruct your ideas, but never his own. You say something about economic growth or Islamofascism, and he wants to talk metaphysics. Just don't bring up metaphysics when he condemns Dick Cheney and Karl Rove. We can't believe in God because religion is unfalsifiable. We can believe in an infinite number of other universes from which no information can ever reach us. Western governments literally spend tens of billions of dollars annually in support of such lunacy. [source]
