Personality is a key antecedent of individual differences in advice-taking from humans. We analyze whether and how personality also influences advice-taking from Artificial Intelligence (AI) systems, which are a promising source of advice to aid human decision-making. It is particularly important to understand advice-taking from AI systems because recent research shows that such systems are often used imperfectly. We consider the Big Five personality traits (extraversion, agreeableness, conscientiousness, neuroticism, and openness) as antecedents of the use of AI advice in a cross-sectional study with 595 participants. The results support our theoretical predictions that agreeableness and neuroticism are associated with an increased use of AI advice. Contrary to our predictions, openness seems associated with a decreased use of AI advice, whereas extraversion and conscientiousness do not seem to be related with the use of AI advice.
