"Humanity either chooses to pursue knowledge or wallow in ignorance; such is the nature of life. This duality is rarely that simple, though, especially in regards to the latter. There are things we dont know, things we cant know, things we shouldnt know, and things we choose not to know. This book will examine particular examples of human ignorance that fall into these categories. From the French Academy of Sciences and its plis cachetés, to moral hazard and adverse selection in insurance, to AI and fake news, to the discovery of dark matter -- this book will look at examples of human ignorance and what we can learn from them"-- Provided by publisher.
