Scientific American reviews Stein’s Expelled:
It speaks to their anti-intellectualism and fundamental misunderstanding of science that for the makers of Expelled (and ID advocates more generally) the answer "we don’t know yet" is a badge of shame. "We don’t know yet" is what defines the fruitful frontier for science; it is what directs scientists’ curiosity and motivates them to spend years on research. Research starts where knowledge and certainty drop off. It’s one of the many ironies of Expelled that Ben Stein says he wants this movie to free people to ask questions about science, but the ID theories he defends would close off inquiry with nonanswers.
Like the decision to call evolution Darwinism, the omission of science from Expelled was a deliberate choice.
In fact, it was crucial to the film’s strategy. Because they know Americans revere freedom of speech and fairness, the producers cast the conflict between evolution and ID as purely a struggle between worldviews—a difference of opinions, a battle of ideologies—in which one side is censoring the other. They know that the public will instinctively want to defend the underdog, especially when that opinion aligns with the religious beliefs many of them already share.
It is a terrific strategy, but with one caveat: that airy skirmish of opinions must never, ever touch the ground of solid evidence. Because if it does, if viewers are ever allowed to notice that evolution is supported by mountains of tangible, peer-reviewed evidence gathered by generations of scientists, whereas ID has little more than a smattering of vanity-press pamphlets from a handful of cranks… the bubble pops.
