Media Use and Public Perceptions of DNA Evidence

This study uses survey data to examine how various forms of media use are related to public perceptions of DNA evidence, including self-perceived understanding of DNA, perceptions of DNA evidence as reliable, weight attached to DNA evidence (or the absence thereof) in jury decision making, and support for a national DNA databank. The hypotheses build on cultivation theory, priming theory, and research regarding the "CSI effect:" The findings indicate that overall television viewing, crime television viewing, and news media use predict perceptions of DNA evidence. Moreover, a question-order experiment produced evidence that priming thoughts about media can influence such perceptions.
