#23 The Dangers of Confirmation Bias with David McRaney: How Do We Fix It?

More than ever America is divided into political tribes.  One person's truth is somebody else's lie. This show is about confirmation bias and filter bubbles: How our brains play tricks on us as we try to make sense of the world.

David McRaney, host of the entertaining and popular podcast, "You Are Not So Smart", is our guest. His show is "a celebration of self-delusion."  David, who calls himself a psychology nerd, is passionate about the need for all of us to have some understanding of how our brains work. He is the author of two recent books:  "You Are Not So Smart" and "You Are Now Less Dumb."

Confirmation bias helps us separate into rival political and cultural camps.  "This is the thing almost from which everything else springs, because it is the natural default way that human beings tend to make sense of the world," says David.

With the growth of Google and social media site, such as Facebook and Twitter, it's easier for us to deny the truth of anything that challenges our preconceived view of the world. We can retreat into our own personal corner of the internet.

Behavioral economics, neuroscience and modern psychology challenge our sense that we make logical, sensible decisions.   Our show looks at what confirmation bias means to our democracy.
