Our guest this week is Michael Shermer, the publisher of Skeptic magazine and head of the Skeptics Society, and a longtime commentator on issues relating to science, critical thinking, and the paranormal.

Chris asked Michael on to discuss his new book, which is entitled The Believing Brain: From Ghosts and Gods to Politics and Conspiracies, How We Construct Beliefs and Reinforce Them As Truths.

Clearly, much of what Shermer has to say here will be of great relevance to skeptics and freethinkers—and along the way, Shermer also discusses his views on global warming (real, but not such a big deal) and how to promote evolution in a religious America.

In addition to publishing Skeptic, Michael Shermer is a monthly columnist for Scientific American, the host of the Skeptics Distinguished Science Lecture Series at Caltech, and Adjunct Professor at Claremont Graduate University. His other books include Why People Believe in Weird Things and Why Darwin Matters.
