The Answers in Genesis Creation Museum opened in May of 2007. During the opening day, a loosely affiliated group of scientists joined in a Rally for Reason as they termed it to protest the museum's potential effect on science in the United States. This paper discusses ethnographic data collected before and during the rally. Scientist narratives disclose the rationale for their participation at the rally, unpacking their hopes, fears and social ideals vis-a-vis their perception of the Museum's impact. With these ideals, I discuss the lacking discourse between the values of ideal of science literacy, the contested authority of museums and their publics, and a lacking conception of how a value rationality aligned towards the Museum's message continues to be culturally produced.
