Decision support for crime scene investigation. On the importance of carefully timed information provision

Activity: Talk or presentationOral presentationAcademic

Description

There is a growing demand for decision support systems to assist forensic investigations in making complex decisions. By providing structured data and scientific insights, these systems can make investigations more efficient and effective. However, reliance on support systems also has potential downsides, such as the risk of creating an echo chamber. Heavy dependence on such systems may limit alternative viewpoints and reduce objectivity. Despite these challenges, thoughtfully designed and applied decision support systems have the potential to enhance quality, transparency and reliability of forensic processes, helping investigators reach well-substantiated conclusions.
This study examines the knowledge requirements of crime scene investigators, with a specific focus on the moments when they require additional information to make complex decisions within a limited time frame. It also explores the impact of the timing of information provision on decision-making. In an experimental setting, 160 forensic professionals examined a virtual crime scene, prioritized the collected evidence for further analysis and completed a questionnaire about their information preferences. Participants received information either before, during or after the crime scene investigation. The questionnaire results indicate that investigators prefer to receive information during the crime scene investigation. The experiment reveals that information provided during the crime scene investigation also most strongly influences investigators’ decision-making. However, this timing also entails the highest risk of biasing the investigation. These findings highlight the importance of carefully timed information provision in forensic investigations, balancing the benefits of decision support with the need to maintain impartiality and minimize risks of cognitive biases.
