Abstract

Many witnesses are intoxicated during the crime, and/or during the investigative interview. Jurors and experts often perceive these witnesses as less credible than sober witnesses. However, the present literature review shows that, in experimental studies, witnesses with a low to moderate blood alcohol concentration (<0.10%) rarely differs from sober or placebo witnesses in terms of accuracy and quantity of information recalled. When a negative effect of alcohol was found, the effect was small and mostly targeted to the quantity of the details and not the accuracy. The present review will further summarize and discuss studies that provide insight into the timing of interviewing intoxicated witnesses (e.g., directly after the crime whilst intoxicated or after a delay when sober), and which interview approach/techniques to use in order to extract as much correct information as possible from intoxicated witnesses.
