Expelled: No Intelligence Allowed is a 2008 American documentary-style propaganda film directed by Nathan Frankowski and starring Ben Stein. The film contends that there is a conspiracy in academia to oppress and exclude people who believe in intelligent design. It portrays the scientific theory of evolution as a contributor to communism, fascism, atheism, eugenics, and in particular Nazi atrocities in the Holocaust. Although intelligent design is a pseudoscientific religious idea, the film presents it as science-based, without giving a detailed definition of the concept or attempting to explain it on a scientific level. Other than briefly addressing issues of irreducible complexity, Expelled examines intelligent design purely as a political issue.

A number of anti-evolution bills have been introduced in the United States Congress and State legislatures since 2001. Purporting to support academic freedom, supporters have contended that teachers, students, and college professors face intimidation and retaliation when discussing scientific criticisms of evolution, and therefore require protection. Critics of the legislation have pointed out that there are no credible scientific critiques of evolution. An investigation in Florida of the allegations of intimidation and retaliation found no evidence that it had occurred. The vast majority of the bills have been unsuccessful, with the one exception being Louisiana's Louisiana Science Education Act, which was enacted in 2008.
