We live in a world where proven facts and verifiable data are freely and widely available. Why, then, are self-confident ignoramuses so often believed over thoughtful experts? And why do seemingly irrelevant details such as a person's appearance or financial status influence whether or not we trust what they are saying, regardless of their wisdom or foolishness? Stephen Martin and Joseph Marks compellingly explain how in our uncertain and ambiguous world, the messenger is increasingly the message. We frequently fail, they argue, to separate the idea being communicated from the person conveying it, explaining why the status or connectedness of the messenger has become more important than the message itself. Messengers influence business, politics, local communities, and our broader society. And Martin and Marks reveal the forces behind the most infuriating phenomena of our modern era, such as belief in fake news and how presidents can hawk misinformation and flagrant lies yet remain.
