viewquake
A sudden drastic shift in someone's view on the world or a particular subject.
informal
This summer, though, one of Hanson's "viewquakes," as he likes to call them, became a genuine national sensation. The only problem was, everybody hated it. Hanson's brainchild was roundly condemned by several U.S. Senators, derided by the likes of Nobel Prize-winning economist Joseph Stiglitz and bond guru Bill Gross, and lampooned by late-night talk show hosts.
Where it comes from
From view + quake, modelled after earthquake. Coined by American economist Robin Hanson.
