Science deniers are not merely uninformed—they are misinformed. How can we get them to change their minds and accept the facts when they don’t believe in facts? In episode 203, Michael Shermer speaks with Lee McIntyre about how to talk to science deniers such as flat earthers, climate deniers, and others who defy reason, and why it’s important to do so.

Bob Schadewald was the leading skeptical authority on the history of flat-Earth advocacy. Now the book he left unfinished has been prepared and published online.

Daniel Loxton shares reflections from George Orwell and George Bernard Shaw on the topics of flat-Earth arguments, expertise, and credulity in an age of scientific marvels.
