The Death of Expertise - Tom Nichols, Oxford University Press (2017)

The essential ideas of this book appeared in The Federalist in 2014.  The book is an expansion of the article. The contents of the book are:

Introduction: The Death of Expertise
Chapter 1: Experts and Citizens
Chapter 2: How Conversation Became Exhausting
Chapter 3: Higher Education: The Customer Is Always Right
Chapter 4: Let me Google that for You:  How Unlimited Information is making us dumber
Chapter 5: The "New" New Journalism and Lots of iIt
Chapter 6: When Experts are Wrong
Conclusion: Experts and Democracy

The book discussed the decline of the public scholar, and the rise of the belief that all opinions are equally valid.   A book well worth reading, though if you read the article, you will learn all about the thesis of the book.  The book contains more examples, and explores consequences.  Example include the anti-vaxx  movement, grade inflation, politics, and a host of others.  The section on the Dunning-Kruger effect - the dumber you are the more confident you are that you're not actually dumb - is a highlight.  If you don't read the book, read the article.
