Abstract

This article explores the paradigm shift in forensic science from the use of definitive absolute conclusions to the application of Likelihood Ratios (LR). It discusses the advantages of LR, including fostering expert collaboration, upgrading the decision-making process, and integrating contradictory evidence. The paper argues that LR, similar to the Jedi approach, embraces complexity and uncertainty, providing a more nuanced and equitable framework for forensic analysis. In addition, we explore specific examples related to forensic handwriting examination to illustrate how LR can clarify and quantify the weight of handwriting comparisons, signature authenticity evaluations, and the examination of questioned documents.
