"Opinions of the shape of the earth differ" journalism was given its name by Paul Krugman in a 2000 op-ed about George W. Bush's alleged campaign trail falsehoods. "If a presidential candidate were to declare that the earth is flat, you would be sure to see a news analysis under the headline ''Shape of the Planet: Both Sides Have a Point.'' After all, the earth isn't perfectly spherical," Krugman wrote.
