Although it is widely assumed that collective apologies for intergroup harms facilitate forgiveness, evidence for a strong link between the two remains elusive. In four studies we tested the proposition that the apology–forgiveness link exists, but only among people who hold an implicit belief that groups can change. In Studies 1 and 2, perceived group malleability (measured and manipulated, respectively) moderated the responses to an apology by Palestinian leadership toward Israelis: Positive responses such as forgiveness increased with greater belief in group malleability. In Study 3, university students who believed in group malleability were more forgiving of a rival university’s derogatory comments in the presence (as opposed to the absence) of an apology. In Study 4, perceived perpetrator group remorse mediated the moderating effect of group malleability on the apology–forgiveness link (assessed in the context of a corporate transgression). Implications for collective apologies and movement toward reconciliation are discussed.
