We’ll go from a world where our bias was to take everything as evidence to one where our bias is to take nothing as evidence…. As truth decays, so too will trust. That would have profound political implications. A world of doubt and uncertainty is good for autocrats and bad for democracy, Chesney and Citron argue. “Authoritarian regimes and leaders with authoritarian tendencies benefit when objective truths lose their power.” In George Orwell’s 1984, the functionaries in Big Brother’s Ministry of Truth spend their days rewriting historical records, discarding inconvenient old facts and making up new ones. When the truth gets hazy, tyrants get to define what’s true. The irony here is sharp. Artificial intelligence, perhaps humanity’s greatest monument to logical thinking, may trigger a revolution in perception that overthrows the shared values of reason and rationality we inherited from the Enlightenment.
