Public Perspectives on Risks and Benefits of Forensic DNA Databases: An Approach to the Influence of Professional Group, Education, and Age

Abstract

There is scarce knowledge about the influence of the professional group, education, and age on public perspectives on the risks and benefits of forensic DNA databases. Based on data collected through an online questionnaire applied to 628 individuals in Portugal, this research fills that gap. More than three quarters of the respondents believed that the Portuguese forensic DNA database can help fight crime more efficiently and develop a swifter and more accurate justice, whereas only approximately half thought that it could deter and prevent crime. Lack of security and control over access to data and the future unforeseen misuses of genetic information were the most relevant risks selected by the participants. Health care and life sciences professionals were more likely to agree with all the benefits, as opposed to those working in the field of law enforcement. More educated and older participants disagreed with benefits more often. Concerns with the risks increased with age.
