Joyful selfies taken at disaster sites create a controversial topic in terms of moral boundaries in digital life. While some consider it acceptable to take smiley selfies in a tragedy zone, others find this behaviour morally questionable. This article demonstrates empirically that excessive time spent on social media explains, at least partially, a greater tendency to like morally ambiguous content on social media. Specifically, this article shows that consumers tend to like more questionable content (such as smiley disaster selfies) on social media when they spend more time online. Further, this article shows that this effect is mediated by increased individualistic thinking. Responses to the survey experiment (N = 206) compared the tendency to like morally ambiguous content between groups of little, moderate and excessive use of social media, and tested for the mediating role of individualistic thinking on the relationship between time spent and liking behaviour. Second, the moderating role of an ethical reminder on time spent and the fact of liking morally ambiguous contents is demonstrated. In the presence of an ethical reminder, the effect of time spent on social media and liking morally ambiguous content becomes insignificant. This article contributes to theory on social media consumption by offering a novel underlying mechanism, such as increased individualistic thinking, as one variable that partly explains the liking for morally ambiguous content. This article also offers practical contributions for social media platforms and policy makers, showing that ethical reminders could be a possible and simple nudge to help consumers act more morally or become aware of morally questionable content. 相似文献
