"The premise of Expelled is that proponents of 'intelligent design' have been shunned, denied tenure, and even fired because of a conspiracy to quash the scientific evidence supporting their theory," said Dr. Keith Lockitch, resident fellow at the Ayn Rand Institute. "But the truth is: there is no evidence supporting their theory. Intelligent design is completely devoid of any positive scientific content, and consists of nothing more than a religiously motivated attack on evolution. To the extent intelligent design advocates are facing obstacles in academia it is because they are not doing real science: they haven't been 'expelled' they have flunked out of the scientific community, just as a faith healer would flunk out of medical school.
