and countered the Holocaust denial movement. This book recounts meeting various denialists and concludes that free speech is the best way to deal with pseudohistory. Science Friction: Where the Known Meets the Unknown was released in 2005. His 2006 book Why Darwin Matters: The Case Against Intelligent Design marshals point-by-point arguments supporting evolution, sharply criticizing intelligent design. This book also argues that science cannot invalidate religion, and that Christians and conservatives can and should accept evolution. In The Mind of The Market: Compassionate Apes, Competitive Humans, and Other Tales from Evolutionary Economics (2007), Shermer reported on the findings of multiple behavioral and biochemical studies that address evolutionary explanations for modern behavior. It garnered several critical reviews from academics, with skeptic Robert T.

In 1994 and 1995, Shermer made several appearances on
