Four studies examined the effect of counterfactual thinking on reactio
ns to rape victims and rape perpetrators. One determinant of counterfa
ctual thinking is whether the event is preceded by an unusual or a usu
al occurrence. In Study 1, the behavior of a rape victim was varied in
this regard, whereas, in Study 2, the behavior of a rape perpetrator
was varied. In Study 3, the usualness and/or unusualness of both victi
m and perpetrator behaviors were varied within the same scenario. Resu
lts indicated that varying these antecedent conditions produced differ
ential reactions to a variety of outcome measures, such as perceived a
voidability, responsibility, regret, blame, and recommended prison sen
tence. In Study 4, these effects were found to generalize to a situati
on involving another proposed counterfactual antecedent: action versus
inaction. Implications for counterfactual thinking and reactions to r
ape are discussed.
