Core claim
Steele (1988) argued that people's fundamental motive is not to defend any particular belief but to maintain overall self-integrity, the sense of being an adequate and good person. Even when self-worth is threatened in one domain, recalling other important values such as family, art or faith keeps the whole self from being shaken, so the need to defend shrinks. Steele and Liu (1983) found that even after inconsistency between behavior and attitudes produced cognitive dissonance, participants given a chance to affirm an important value showed less attitude change to rationalize it.
Reducing defensive responses
Sherman and Cohen (2006) reviewed studies showing that self-affirmation leads people to process threatening messages, such as health risk information, opposing political views and information about their group's wrongdoing, more openly. For example, smokers and caffeine drinkers who affirmed their values derogated health warnings less and showed greater intention to change. McQueen and Klein (2006) found that asking people to choose their most important value and write about why it matters is the most widely used manipulation. Critcher and Dunning (2015) proposed that affirmation works by placing a threat in the broader context of one's life, reducing its weight.
Interventions and limits
Cohen and colleagues (2006) reported a field experiment in which middle school students wrote for about 15 minutes about important values a few times early in the term; Black students' grades rose and the racial achievement gap narrowed. This drew attention as a way to ease stereotype threat. Cohen and Sherman (2014) explained that brief interventions can have lasting effects by interrupting recursive cycles in which threat and performance reinforce each other. Later large-scale replications, however, found smaller effects or effects that varied with school context, so research continues on the conditions under which affirmation works.
FAQ
- What is self-affirmation theory in simple terms?
- Even if your pride is hurt in one area, recalling another value that matters to you keeps you steadier, so you can accept uncomfortable information less defensively.
- How is self-affirmation done?
- In experiments, people usually choose their most important value from a list and write a few sentences about why it matters to them.
