Ben Stein's movie, Expelled, is not a documentary. It is a way to further inject mal-thinking into the cultural trend towards non-scientific attitudes. This trend is nothing new and years ago I discussed it with my children when we read Carl Sagan's book The Demon-Haunted World: Science as a Candle in the Dark.
Pseudoscience differs from erroneous science. Science thrives on errors, cutting them away one by one. False conclusions are drawn all the time, but they are drawn tentatively. Hypotheses are framed so that they are capable of being disproved. A succession of alternative hypotheses is confronted by experiment and observation. Science gropes and staggers toward improved understanding. Proprietary feelings are of course offended when a scientific hypothesis is disproved, but such disproofs are recognized as central to the scientific enterprise.
Pseudoscience is just the opposite. Hypotheses are often framed precisely so they are invulnerable to any experiment that offers a prospect of disproof, so even in principle they cannot be invalidated. Practitioners are defensive and wary. Skeptical scrutiny is opposed. When the pseudoscientific hypothesis fails to catch fire with scientists, conspiracies to suppress it are deduced.
Exposed follows the pattern of pseudosciences.
In thinking about the controversy, I wonder why science is accepted when it comes to flying planes, making paint stick to walls, improving hair conditioners, growing food, making computers, funneling electricity into homes, flying rocketships to the moon, Mars, Saturn and beyond, and millions of other everyday wonders. Yet, when it comes to analyzing the evidence of Earth's earlier years, and earlier inhabitants, this same science is decried by some people. I'd like to see an explanation of why science works so well elsewhere, but founders on the shoals of studing Earth's inhabitants.
I'll save my breath concerning the challenges to the evolutionary theory, but I will make one comment -- creation and evolution are two different subjects. Creation is about how it all started. Evolution is about what happened afterwards. They aren't the same thing.
In any case, one thing those of us who are concerned about the spread of mal-thinking can do, is link to the Expelled Exposed website.
