The Dirty Dozen: 12 Sources of Bias in Forensic Neuropsychology with Ways to Mitigate

Abstract

The ever expanding role of a forensic neuropsychologist in civil litigation has rightfully led to a higher level of expectation for this expert, in realms such as clinical and courtroom knowledge, objectivity, and work product utility. The onus is on forensic neuropsychologists to ensure that these expectations are met. Recognizing that bias is inherent in clinical and forensic work, it is imperative that in high stakes situations such as forensic neuropsychological assessment, the evaluator is proactively conscientious in recognizing, and minimizing, the effects of these biases. This article highlights 12, of many, common biases about which the prudent forensic neuropsychologist should always be mindful of, during evaluation as well as the provision of deposition or trial testimony. Role, cognitive, and practice biases are defined and illustrated with examples. Specific suggestions are extracted from both empirical literature and forensic experience on how to recognize and mitigate these biases. The information contained in this article is intended to provide sound and practical strategies that can be useful for forensic neuropsychological practitioners. Attorneys will also find the content useful when working with such experts, including during deposition and cross examination preparation.
