Effects of Cognitive Bias in Forensic Mental Health Evaluation and Possible Solutions: Focused on Taiwanese Criminal Procedure
Forensic mental health evaluation plays an important role in criminal procedure. However, these evaluation results might be affected by cognitive bias, and thus affect the rulings of the court. While there are many different types of cognitive bias, the researches regarding forensic mental health evaluation mostly focus on confirmation bias, representativeness heuristics, anchoring effect, and allegiance effect. This paper therefore first briefly introduces these four types of bias, then focuses on the possibility of confirmation bias existing in forensic mental health evaluation in Taiwan, and discusses the possible solutions.
