摘要

Understanding and coping with cognitive bias in forensic science requires multiple studies, utilizing both laboratory-based experiments and data from casework. Neither type of studies has ever been conducted to examine bias in mixture DNA interpretations. A study that includes both types of data has recently been published in Science and Justice. The data and statistical analysis clearly 鈥?at the very least 鈥?suggest that bias may potentially influence DNA mixture interpretation. This is due, in part, to the subjective elements in interpretation of mixture DNA. The issue of bias and other cognitive influences is of a sensitive nature and presents complex experimental challenges. Our study takes a step in examining these issues and calls for more research.
