The present research highlights affiliation defenses in the psychological confrontation with death. In 3 experiments, it was found that mortality salience led to increased affiliation strivings, as indicated by a greater preference for sitting within a group as opposed to sitting alone. Mortality salience actually led to increased affiliation with a worldview-threatening group (Experiments 1-2), even when affiliation with the group forced participants to attack their own worldviews (Experiment 3). Taken together, the findings support a distinct role of affiliation defenses against existential concerns. Moreover, affiliation defenses seem powerful enough to override worldview validation defenses, even when the worldviews in question are personally relevant and highly accessible.
