Pain(less) cleansing: Watching other people in pain reduces guilt and sadness but not shame.

Abstract

Past research has shown that pain experience reduces feelings of guilt for earlier wrongdoings. In this paper, we aim to investigate whether watching other people in pain can reduce feelings of guilt. In Study 1 (N = 60), we found that participants' levels of guilt and sadness decreased after they watched a one-minute movie clip showing a painful medical procedure. Study 2 (N = 156), eliminated an alternative explanation in which pain observation but not the misattribution of unrelated excitation reduced guilt. Finally, in Study 3 (N = 60), pain observation lowered participants' feelings of guilt but not their feelings of shame. Overall, these results suggest that the guilt-reducing effect of pain may appear even without the actual experience of physical pain.
