The New Atheists are big fans of reason. Sam Harris' Project Reason, Victor Stenger's "The New Atheism: Taking a Stand for Science and Reason", Richard Dawkins' Foundation for Reason and Science, etc.
Sounds admirable, doesn't it? Who isn't in favor of reason? After all, reason is what makes us, well… reasonable, right? Reason is what separates us from the lower animals. Reason is how we make right choices. Reason guides us to the truth, right?
Not so fast. Professors Hugo Mercier and Dan Sperber want to show you the darker side of reason.
