<p>The present investigation had the objective of analyzing discrimination against Muslim immigrants through two types of social dilemma personal dilemma and impersonal dilemma. Previous studies have identified that, depending on the type of social dilemma, this may favor automatic processes or controlled information processes. We hypothesized that in the personal dilemma scenario, which favors processes of automatism, the conduct of favoring the ingroup member (Spanish) to the detriment of the outgroup member (Muslim immigrant) would be observed. On the other hand, in the impersonal dilemma scenario, where processes of self-control predominate, the conduct in favor of the outgroup member (Muslim immigrant) would be more frequent than the conduct in favor of the ingroup member (Spanish). Additionally, present study had the additional objective of verifying how adherence to different human values influences the expression of discriminatory behavior. A total of 235 university students participated in this investigation, all of them of Spanish nationality with ages between 18 and 28 years (M = 20.83, SD = 5.6). The results indicated that, in the personal dilemma scenario, most participants chose to harm the outgroup member&nbsp; in favor of the survival of the ingroup that was threatened. On the other hand, in the impersonal dilemma scenario, the decision to manifest helping behavior toward the outgroup member&nbsp; was more frequent than that of helping the ingroup member, which corroborates our Hypotheses. In addition, this Study has identified that conservation values are associated with greater ingroup favoritism&nbsp; in both dilemma scenarios.</p>
