"A democracy falters when most of its citizens are uninformed or misinformed, when misinformation affects political decisions and actions, or when political actors foment misinformation -- the state of affairs the United States faces today, as this timely book makes painfully clear. In Do Facts Matter? Jennifer L. Hoschschild and Katherine Levine Einstein start with Thomas Jefferson's ideal citizen, who knows and uses correct information to make policy or political choices. What, then, the authors ask, are the consequences if citizens are informed but do not act on their knowledge? More serious, what if they do act, but on incorrect information? Analyzing the use, nonuse, and misuse of facts in various cases ... Hochschild and Einstein argue persuasively that errors of commission (that is, acting on falsehoods) are even more troublesome than errors of omission. While citizens' inability or unwillingness to use the facts they know in their political decision making may be frustrating, their acquisition and use of incorrect 'knowledge' pose a far greater threat to a democratic political system. Do Facts Matter? looks beyond the individual citizens to the role that political elites play in informing, misinforming, and encouraging or discouraging the use of accurate or mistaken information or beliefs. Finally, the authors consider policy levers and political actions that leaders and citizens can use to disseminate politically relevant knowledge, connect information to action, and correct or compensate for the use of misinformation. As Will Rogers once remarked, 'It isn't what we don't know that gives us trouble. It's what we know that ain't so.' Hochschild and Einstein show that if a well-informed electorate remains a crucial component of a successful democracy, the concealment of political facts poses its greatest threat."--Jacket.
