Moral outrage is an emotion elicited by civilization itself, but civilization is rapidly stimuli appraised as signifying moral norm violations. The subjective experience of outrage in reaction to changing in the face of new technologies. such stimuli motivates the expression of behavioural responses such as gossip, shaming or punishment. Worldwide, more than a billion people now Expressing outrage can lead to positive and negative outcomes for oneself and for society. Digital media spend at least an hour a day on social media, may promote the expression of outrage by magnifying its triggers, reducing its personal costs and and moral outrage is all the online.

Fig. 2 | Exposure to immoral acts and resulting moral outrage, online versus offline. In a previous study3, people’s smartphones were signalled five times a day for three days to sample everyday moral experiences in a geographically and demographically diverse sample of North American adults (N =​ 1252). a, A reanalysis of this data revealed that participants were more likely to learn about immoral acts online than in person or via traditional forms of media (print, television and radio; χ2 =​ 9.51, P =​ 0.009). The figure displays the percentage of total reported moral/immoral acts that were learned about in each setting. b, For each immoral act, moral outrage was calculated by multiplying self-reported anger and disgust1. Moral outrage ratings were entered into a linear mixed- effects model using the MIXED command in SPSS with setting type (traditional media, in person or online) as a categorical BY variable. This revealed that immoral acts encountered online evoked more outrage than immoral acts encountered in person (t(771) =​ 2.723, P =​ 0.007) or via traditional forms of media (t(762) =​ 4.555, P <​ 0.001).
