A review of some recent well-documented cases of intolerance in the cosmology field illustrates a common problem in science. Many relate to the Big Bang theory, such as the case of Geoffrey and Margaret Burbidge and Halton Arp. None of the accounts involved Intelligent Design advocates or creationists. This selection removes this compounding factor from the evaluation, but the cases have direct relevance to both Intelligent Design and creationism because both groups face the same resistance. It was concluded that it is critical for science to advance that new ideas must be evaluated on the evidence and not because they challenge established science. This problem has persisted during the entire history of science, the most well known example being Galileo.
