Roger Ailes built Fox News into television's most powerful channel by his skillful adaptation of the aphorism, "if you tell them what to think, you lose them. If you tell them what to feel, they're yours." The replacement of reason with emotion, a favored trick of conjurers and con men that's as old as Mark Antony's eulogy for Julius Caesar, has created a new reality and battered America's democratic guardrails. In this episode of Common Ground with Jane Whitney, a diverse panel from across the political spectrum discusses how the country, which once elevated science into the unofficial national religion, came to accept the parasitic oxymoron of "alternate facts" and how so many of us have come to live in an impenetrable bubble that elevates ill-considered opinion into intractable certitude.
