The vulnerability of values to attack: inoculation of values and value-relevant attitudes.
Based on the values-as-truisms hypothesis and inoculation theory, two experiments tested whether providing cognitive defenses for the value of equality induces resistance against a message attacking this value. Experiment 1 found that participants who generated cognitive support in an active-supportive or an active-refutational defense were less persuaded by a subsequent message attacking equality than were participants who engaged in no prior defense. Experiment 2 examined the effects of an active-refutational defense and a passive-refutational defense, which simply asked participants to read reasons supporting or opposing equality. Results indicated additive effects of the active and passive defenses, such that participants were most resistant to the anti-equality message when they were given both defenses. Mediational analysis across both experiments revealed that the defenses increased counterargumentation of the anti-equality message, which led to increased post-attack importance of equality and predicted more favorable equality-relevant attitudes and values.
