“…More specifically, we investigate how the severity of an incident predicts bystander interventions. Previous researchers have shown that bystanders are more likely to intervene in more severe incidents than in less severe ones (Bastiaensens et al, , 2015Kazerooni, Taylor, Bazarova, & Whitlock, 2018;Obermaier et al, 2016;Patterson, Allan, & Cross, 2017a,b). Researchers usually operationalize differences in incident severity as either an "objective" characteristic of different bullying incidents (e.g., Kazerooni et al, 2018;Obermaier et al, 2016) or as differing perceptions of the severity of the same incident (e.g., Patterson et al, 2017a).…”
