This talk presents five experimental studies that test the hypothesis that gratitude predicts greater obedience. Studies 1 to 4 showed that participants who were induced to feel grateful (using recall or realistic method) were more likely to obey instructions to put live worms into a grinder than those induced to feel a neutral state, joy, or admiration. Study 5 showed that induced gratitude made participants more prone to obey instructions to lie for more monetary incentives in a die-rolling game than induced neutral and joy states. This effect of gratitude disappeared among grateful participants who were led to devalue social harmony, suggesting that the gratitude-obedience effect is due to the greater need to maintain social relations. The findings support the social-alignment perspective that because of a stronger tendency to align with social conventions and directions, gratitude increases the tendency to conform and obey, leading to a range of outcomes some of which may not be socially desirable.
