TY - JOUR PY - 2022// TI - Law and order effects: on cognitive dissonance and belief perseverance JO - Psychiatry, psychology and law A1 - Maegherman, Enide A1 - Ask, Karl A1 - Horselenberg, Robert A1 - Van Koppen, Peter J. SP - 33 EP - 52 VL - 29 IS - 1 N2 - Order of evidence presentation affects the evaluation and the integration of evidence in mock criminal cases. In this study, we aimed to determine whether the order in which incriminating and exonerating evidence is presented influences cognitive dissonance and subsequent display of confirmation bias. Law students (Nā=ā407) were presented with a murder case vignette, followed by incriminating and exonerating evidence in various orders. Contrary to a predicted primacy effect (i.e. early evidence being most influential), a recency effect (i.e. late evidence being most influential) was observed in ratings of likelihood of the suspect's guilt. The cognitive dissonance ratings and conviction rates were not affected by the order of evidence presentation. The effects of evidence presentation order may be limited to specific aspects of legal decisions. However, there is a need to replicate the results using procedures and samples that are more representative of real-life criminal law trials.
