Media Use and Public Perceptions of DNA Evidence

<jats:p>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.</jats:p>
