The ideological Turing test (sometimes called the political Turing test (Hannon 2020: 10)) is a test of a person's ability to state opposing views as clearly and persuasively as those views are stated by their proponents. The test was originally proposed by Bryan Caplan (Caplan 2011), in analogy with Alan Turing's "imitation game"—more widely known as the Turing test—, which measures a machine's ability to exhibit intelligent behaviour indistinguishable from that of a human.
