Susan Jacoby scanned the American culture and found a prevalence of what she calls "junk thought."
So she wrote a book, The Age of American Unreason in a Culture of Lies. And that was nine years ago.
Just think of how much more there is to talk about now, in the age of daily lies from public figures and cries of "fake news."
Susan Jacoby updated her book to include the current political players and the likes of Breitbart News and Twitter, all contained in a new paperback edition.
She joins us to talk about the disturbing trends.
