However, the consequence of learning about whether your own ethnic group is either genetically related to or genetically distinct from a disliked ethnic group remains unknown. Across four experiments, using diverse samples, measures and contexts, we demonstrate that altering perceptions of genetic overlap between groups in conflict\u2014in this case Arabs and Jews\u2014impacts factors that are directly related to interethnic hostility (e.g., aggressive behaviors, support of conflict-related policies). Our findings indicate that learning about the genetic difference between oneself and an ethnic outgroup may contribute to the promotion of violence, whereas learning about the similarities may be a vital step toward fostering peace in some contexts. Possible interventions and implications are discussed.<\/jats:p>","DOI":"10.1177\/0146167216642196","type":"journal-article","created":{"date-parts":[[2016,3,30]],"date-time":"2016-03-30T21:38:52Z","timestamp":1459373932000},"page":"688-700","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":42,"title":["Living in a Genetic World"],"prefix":"10.1177","volume":"42","author":[{"given":"Sasha Y.","family":"Kimel","sequence":"first","affiliation":[{"name":"Harvard University, Cambridge, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rowell","family":"Huesmann","sequence":"additional","affiliation":[{"name":"University of Michigan, Ann Arbor, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonas R.","family":"Kunst","sequence":"additional","affiliation":[{"name":"Harvard University, Cambridge, MA, USA"},{"name":"University of Oslo, Norway"},{"name":"University of Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eran","family":"Halperin","sequence":"additional","affiliation":[{"name":"Interdisciplinary Center, Herzliya, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,3,30]]},"reference":[{"key":"e_1_3_4_2_1","unstructured":"Abraham Fund History and Vision.
