Historian Dan Carlin, who built a following by narrating civilizational collapses, is now drawing parallels between historical breakdowns and present-day American fracture. In conversation with Kmele Foster, Carlin argues that the nation's inability to maintain a common factual foundation represents a fundamental shift from previous eras. He contrasts the information landscape of the 1980s, when misinformation spread through physical flyers, with today's digital deluge where competing narratives proliferate instantaneously and without gatekeeping. Carlin connects this erosion of shared reality to constitutional design: the Framers built a system intended to prevent tyranny at the cost of efficiency, a tradeoff that held as long as citizens operated from broadly similar understandings of fact. He also examines Congress's decades-long abdication of its war-declaration powers, arguing this shift has fundamentally rebalanced executive authority in ways the Constitution didn't anticipate. The implication is stark: democratic institutions designed for a population with overlapping truths may struggle when that overlap vanishes.
