We live in an age of ignorance. This book offers a guide to how we got here—and how we might escape. From obfuscations of climate science to the myriad deceptions inhering in language, Ignorance Unmasked explores how agnotology—the study of ignorance—can help us better grasp: Why don't we know what we don't know? What are the obstacles to knowledge, and how might those be overcome? Ignorance has countless agents and authors; it gets deliberately manufactured and widely disseminated.
