Lies destroy. Disinformation tears at the fabric of democracy. A Firehose of Falsehood: The Story of Disinformation breaks down disinformation tactics and offers tools for defending and restoring truth. From Darius I of ancient Persia (522-486 BCE), to blood libel of the Middle Ages, to Soviet disinformation tactics and modern election deniers, Teri Kanefield and Pat Dorian show how tyrants and would-be tyrants deploy disinformation to gain power. Democracy, which draws its authority from laws instead of the whim of a tyrant, requires truth. For a democracy to survive, its citizens must preserve and defend truth. Now that the Internet has turned what was once a trickle of lies into a firehose, the challenge of holding on to truth has never been greater. A Firehose of Falsehood offers readers these necessary tools.
