“…Researchers, therefore, need to control for and eliminate the effect of prior contact with the secondary outgroup(s). Several studies (e.g., Hindriks et al, 2014;Meleady & Forder, 2019;Schmid, Hewstone, Küpper, Zick, & Wagner, 2012;Schmid et al, 2014;Tausch et al, 2010;Ünver et al, 2021;Van Laar et al, 2005;Vezzali & Giovannini, 2012;Zezelj et al, 2020) still found evidence supporting the STE, when contact with the secondary outgroup was controlled. Schmid et al (2012), for instance, included prior contact with secondary outgroups, i.e., homosexuals and Jews, as a control variable and found evidence for STE in their large-scale study conducted in eight European counties with over seven thousand participants.…”
