“…We only considered studies where HIs between identity groups was a main independent variable, excluding studies which only use HI as a control term 3 . The identified studies focus on a variety of political violence outcomes, including civil conflict (Bodea et al., 2017; Cingranelli et al., 2019; Das, 2019; Hillesund, 2019b; Lessmann & Steinkraus, 2019; Tollefsen, 2020), non‐state conflict (Alcorta et al., 2018, 2020; Hillesund, 2019b; Rudolfsen, 2017) coups (Bodea et al., 2017; Houle & Bodea, 2017), other forms of social unrest, such as ethnic and other riots (Abbs, 2021; Bodea et al., 2017; Cingranelli et al., 2019; Mcdoom et al., 2019) and domestic terrorism (Cingranelli et al., 2019; Fleming et al., 2022; Hansen et al., 2020; Treistman, forthcoming), or a combination of these (Cao, Duan, Liu, Piazza, et al., 2018; Cao, Duan, Liu, & Wei, 2018; Hodler et al., 2020). Two studies focus on individuals’ propensity to support the use of violence: Nanes (2021), on support for the use of anti‐state violence in Iraq, and Treistman (forthcoming), on individual's support for terrorism.…”
