| Abstract: | The results of fingermark examination are used as evidence in the justice system and are generally viewed as scientific and robust. However, as human experts are the main instrument of analysis, human error can occur because of subjectivity and flaws in the ACE-V methodology. Therefore, a computer assisted consensus approach is tested. This means participants are instructed to use the software PiAnoS to support their decision-making process and later in establishing a consensus. The PiAnoS software can track which features of a fingerprint have been marked for analysis and comparison, hence supporting the discussion on those features during the consensus approach. To account for potential pitfalls of the consensus approach, 23 participants consisting of fingermark examiners and students all with different levels of expertise engaged in group discussions on ten marks of differing complexity, with surveys administered before and after. The initial survey served as a baseline for the variables, psychological safety and stress. The subsequent survey captured negative group behaviours, psychological safety, and stress. Psychological safety is assumed to be a prerequisite for a successful discussion in a team. The work environment of fingerprint examiners includes factors that enhance stress. This could be disruptive to effective decision making, therefore stress experienced during the consensus approach is explored. Results indicate higher psychological safety and lower stress during the computer assisted consensus approach compared to baseline measures. Negative group behaviours occurred at an acceptable frequency. Hence, the computer-assisted consensus approach is recommended for future deployment in fingerprint examination, albeit requiring further testing in the workplace. |
