An experiment was performed to test whether a moderate dose of alcohol (1 ml of 100% alcohol/kg body weight) facilitates the production of creative solutions as measured with a standard creativity test and whether a creative attitude interacts with alcohol in this respect. The 60 subjects were randomly assigned to either an alcohol, a placebo, or a control group, with 10 women and 10 men in each group. Two different personality tests measuring the creative attitude were administered a priori. Analysis indicated that both the placebo and alcohol groups produced significantly less creative solutions to the ten stimulus pictures. The a priori attitude scores significantly predicted the creativity scores for the placebo and alcohol subjects but not for the control subjects. Results were discussed in terms of disinhibition and cognitive changes under alcohol.
