Crocker, J., Niiya, Y., & Mischkowski, D. (2008). Why does writing about important values reduce defensiveness? Self-affirmation and the role of positive other-directed feelings. Psychological Science, 19, 740-747.
Previous research has repeatedly shown that writing about an important value, compared with writing about an unimportant value, reduces defensiveness in response to self-threatening information, but has not identified why. Study 1 showed that participants who wrote about an important value reported more positive other directed feelings, such as love and connection, than participants who wrote about an unimportant value. Study 2 replicated this effect, and showed that loving and connected feelings, but not positive or negative self-directed feelings, completely accounted for the effect of a values affirmation manipulation on smokers’ acceptance of information indicating that smoking harms health. These studies, in concert with previous research, suggest that values affirmation reduces defensiveness via self-transcendence, rather than self-integrity (i.e., self-worth or self-images).
