Science in the Courtroom

• In Event: Poster Session

Abstract

Media coverage has a pronounced impact on public perceptions of crime and the criminal justice process. Recently, there has been concern that unsophisticated consumers of televised science expect too much from forensic experts. This study attempted to determine general knowledge and understanding of forensic evidence among a sample of college students. Using mock case scenarios, students (N = 485) in a large Southwestern university were surveyed about forensic evidence and trial outcome. The results indicate that perceived strength of forensic evidence was a strong determinant of jury verdict. However, when questioned about basic understanding of fingerprint and DNA evidence, respondents were less well informed than expected. Qualitative and quantitative data are reported on knowledge of DNA and fingerprint analysis, and interpretation of probability statements will be presented.
