Via a book review by Daily Kos:
Given the title readers might be forgiven for assuming this is a purely partisan pseudoscientific attack—projection being all the rage on the right these days, eh? In fact the book is quite fair, the author carefully reviews instances where non conservatives resist evidence. He writes early on and illustrates throughout it's not that liberals or independents are always right about science, it's that, lately, conservatives are wrong a lot. From all outward appearances they often seem to be sincerely unaware of how wrong they are. At times they can even make a good faith effort to grasp why they're wrong and still fail. The book also introduced something new, at least for me, called the smart idiot effect: the more educated conservatives are, the more sure they are about their false beliefs.
I think this will be a book that all progressives will want to read, I know that I do!
