Researchers from the Center for Statistics and Applications in Forensic Evidence (CSAFE) wrote an article for Psychology Today that discusses their latest publication, “A practical tool for information management in forensic decisions: Using Linear Sequential Unmasking-Expanded (LSU-E) in casework.”
The article was co-authored by Jeff Kukucka, an associate professor of psychology at Towson University; Brandon Garrett, CSAFE co-director and the L. Neil Williams, Jr. Professor of Law and director of the Wilson Center for Science and Justice at Duke University; and Adele Quigley-McBride, a post-doctoral fellow at Duke University, along with Tiffany Roy from ForensicAid.
To provide guidance on how forensic laboratories can take practical steps to minimize error, the authors developed a worksheet that labs and analysts can use to document and optimize their decision-making processes. The worksheet is free to download and can be tailored to any forensic discipline.
Excerpt from the article:
To encourage and facilitate the use of LSU-E, we recently developed and published a worksheet that analysts can use to record the sources of information that guided their analysis and when they considered each. The worksheet walks analysts through their consideration of the information available to them, asks them to rate each item along three criteria (objectivity, relevance, and biasing power), and encourages them to describe any steps taken to mitigate its potential biasing effect.
In addition, we developed training materials and examples of how to rate and consider different kinds of information that are often available to analysts. In theory, this worksheet should also help non-experts (e.g., judges and juries) make informed decisions about the trustworthiness of the resulting forensic opinion by increasing transparency about the basis for the analyst’s opinion, whether and how their opinion evolved over time, and whether they took appropriate steps to avoid bias.
