This study examined differences in class attendance at different levels of conscientiousness and incentives (3.5% vs. 6% of course points). Results of a 2 × 2 (Level of Incentives × Level of Conscientiousness) ANOVA indicated a significant main effect for conscientiousness. Conscientiousness accounted for 14% of the variance in attendance, compared to 1% for incentives. Attendance appears to be influenced more by conscientiousness than by incentives
