In recent years, scholars have levied multiple criticisms against traditional proficiency testing procedures in forensic laboratories. Consequently, on several occasions, authorities have formally recommended that laboratories implement blind proficiency testing procedures. Implementation has been slow, but laboratory management has increasingly expressed interest in initiating blind testing in at least some forensic disciplines, with some laboratories conducting blind testing in almost all disciplines. However, little is known about how a key population perceives blind proficiency testing, i.e., forensic examiners. We surveyed active latent print examiners (N = 338) to explore perceptions of blind proficiency testing and determine whether beliefs varied between examiners who work for laboratories with and without blind proficiency testing. Results suggest that examiners do not hold particularly strong beliefs about such procedures, but that examiners who work in laboratories with blind proficiency testing procedures view them significantly more positively than those who do not. Further, examiner responses provide insight into potential obstacles to continued implementation.
近年来,学者们对法医实验室传统的能力验证程序提出了多项批评。因此,有关部门曾多次正式建议实验室实施盲样能力验证程序。尽管实施速度缓慢,但实验室管理层对至少在某些法医学科中启动盲样测试越来越感兴趣,一些实验室几乎在所有学科中都进行盲样测试。然而,对于关键人群(即法医鉴定人)如何看待盲样能力验证,人们知之甚少。我们调查了活跃的潜在指纹鉴定人(N=338),以探讨他们对盲样能力验证的看法,并确定在有无盲样能力验证的实验室工作的鉴定人之间的看法是否存在差异。结果表明,鉴定人对这些程序的看法并不特别强烈,但在有盲样能力验证程序的实验室工作的鉴定人对其评价明显高于没有的鉴定人。此外,鉴定人的反应为进一步实施提供了潜在障碍的见解。
