The drunk side of trust: Generalized and instantaneous trust at gathering events

We present novel evidence on the nexus between alcohol intake and trust at a large cultural gathering event. Throughout six editions, we interviewed nearly 2,000 attendees and collected an objective measure of alcohol intake (Blood Alcohol Concentration, BAC) using electronic breathalyzers and self-perceived measures of intoxication. We elicited different self-reported trust measures toward eventgoers and the general public. While alcohol intoxication is not correlated with trust toward the general public, there is a positive and significant nexus between alcohol intake and trust toward the other participants in the event (Instantaneous trust). Only a small part of this effect (15%) is driven by an increased trust in other drinkers at the event. Taken together, these findings indicate endogenous group formation regarding alcohol intake. •Limited research exists on moderate drinking’s effects on trust, risk aversion, and impulsiveness.•We study alcohol’s impact on trust at the event “La Notte della Taranta” with objective intoxication measures.•Objective data reveals alcohol’s unique impact on trust.•No direct link found between generalized trust and alcohol intake.•Alcohol consumption correlates positively with instantaneous trust, especially among like-minded attendees.
