Participants (N = 251) used an Internet-based information board to learn about fictional U.S. presidential candidates in a voting simulation task. Need for cognition and conscientiousness interacted to predict political interest. Participants high in need for cognition and participants high in conscientiousness, regardless of the magnitude of the other construct, exhibited high political interest. Participants low in need for cognition and conscientiousness exhibited low political interest. Additionally, participants high in need for cognition or low in conscientiousness preferred an issue-based voting strategy, whereas those low in need for cognition or high in conscientiousness preferred a candidate-based voting strategy. These findings have important implications for how political information should be disseminated to voters through Internet means, such as political websites.
