While children evaluate bystanders who do not offend victims negatively, it is unclear whether they would punish them. This study consolidates findings from 1 pre-study and 4 experiments (3-8-year-olds; N = 192; 49% girls; 100% Asian) that examine children's punishment judgment of bystanders in various contexts. The results revealed that children engaged in punishment not only of the wrongdoer but also of the non-intervening bystander. However, they did not punish the bystander who intervened in the negative situation. Additionally, children adjusted their punishment judgment for the bystander upon considering whether the wrongdoer and bystander shared group membership and the intention to harm the victim (odds ratio = 5.08). Implications for how bystanders are morally judged are discussed.
