Witnesses and suspects are frequently intoxicated during their first interview. Alcohol impairs executive functioning (e.g. impulse control, judgement), which in turn could have negative consequences for interviewee behaviour (e.g. oversharing sensitive information). In a legal context, interviewees’ willingness to disclose either a personal transgression or someone else’s transgression is often of great importance. Participants were randomly assigned to a 3 (Beverage: alcohol vs. placebo vs. control) x 2 (Transgression type: self vs. other) between-participants design. While drinking in the bar lab, all participants witnessed the bartender taking a shot of vodka asking them not to tell anyone. Afterwards, half of the participants were asked to report if they noticed the bartender commit a transgression. The other half were asked to report a personal transgression, defined as something unethical. Data-collection is ongoing; all interviews will be scored for whether a transgression was reported, and the number of details disclosed about the transgression.
