The present research investigated the effects of counterfactual thinki
ng on the interpretation of criminal behaviour. It was predicted that
the availability of counterfactual alternatives for a crime would affe
ct a range of incident-related judgements. The results of two studies
strongly supported this prediction. When counterfactual alternatives t
o an outcome were readily available, subjects: (i) punished the perpet
rators more severely; (ii) considered the incident to be more serious;
and (iii) felt greater sympathy toward the victims. In addition, the
results confirmed earlier research in this domain and demonstrated tha
t counterfactual effects on judgemental processes are mediated by subj
ects' affective reaction towards events. The wider implications of the
se findings and their potential implications for judicial decision mak
ing are considered.
