The reason has to do with the way that metaphorical thought and language work in the brain. From a cognitive linguistics perspective, “fiscal cliff” is not a simple metaphor bringing “fiscal” together with “cliff.” It is instead a linguistic metaphor that is understood via a highly integrated cascade of other deeper and more general conceptual metaphors.
A cascade is a neural circuit containing and coordinating neural circuits in various parts of the brain.
Because we think with our brains, every thought we have is physical, constituted by neural circuitry. Because about 98 percent of conscious thought has an unconscious neural substrate, we are rarely aware of conceptual metaphors. And because the brain is a physical system governed by conservation of energy, a tightly integrated cascade of neural metaphor circuits is more likely to be learned, remembered, and readily activated.
