Mercy Corps conducted a survey of Yazidi households in Sinjar and IDP camps in Duhok governorate to explore the conditions under which they were more or less likely to accept returnees. The findings show that returnees’ movement patterns during ISIS rule shapes their social acceptance more than ethnoreligious identity; a sense of shared victimhood under ISIS makes Yazidis, especially men, more likely to accept Sunni returnees; and Yazidi respondents who were displaced with Sunnis and interacted with them more frequently were more likely to accept them into their communities.
