Positive attitudes and trust towards former adversaries facilitate reconciliation and peacebuilding. Both historical and current intergroup experiences such as intergroup contact and conflict predict intergroup attitudes and trust but no previous research has investigated the joint effects of these experiences. Therefore, we study the interplay of positive intergroup contact preceding conflict, negative experiences of the conflict, and positive intergroup contact following conflict. Drawing on social representations theory and using a multilevel design, we highlight the importance of both individual and collective experiences. We examine the effects of such experiences on intergroup attitudes and trust among a large sample of Greek Cypriots (N = 802) and Turkish Cypriots (N = 718) from 54 formerly ethnically mixed villages in the context of a protracted and frozen conflict in Cyprus. Present day individual contact related to more positive attitudes and higher trust regardless of past experiences of conflict or contact. Furthermore, past collective contact experiences predict more positive attitudes and higher trust, whereas past collective conflict experiences predicted more negative attitudes and lower trust. Finally, present-day contact closes the gap in trust between respondents with low and high past contact. Overall, both current and historical, and individual and collective experiences matter.

We conducted preregistered replications of 28 classic and contemporary published findings, with protocols that were peer reviewed in advance, to examine variation in effect magnitudes across samples and settings. Each protocol was administered to approximately half of 125 samples that comprised 15,305 participants from 36 countries and territories. Using the conventional criterion of statistical significance (p <.05), we found that 15 (54%) of the replications provided evidence of a statistically significant effect in the same direction as the original finding. With a strict significance criterion (p <.0001), 14 (50%) of the replications still provided such evidence, a reflection of the extremely highpowered design. Seven (25%) of the replications yielded effect sizes larger than the original ones, and 21 (75%) yielded effect sizes smaller than the original ones. The median comparable Cohen's ds were 0.60 for the original findings and 0.15 for the replications. The effect sizes were small (< 0.20) in 16 of the replications (57%), and 9 effects (32%) were in the direction opposite the direction of the original effect. Across settings, the Q statistic indicated significant heterogeneity in 11 (39%) of the replication effects, and most of those were among the findings with the largest overall effect sizes; only 1 effect that was near zero in the aggregate showed significant heterogeneity according to this measure. Only 1 effect had a tau value greater than.20, an indication of moderate heterogeneity. Eight others had tau values near or slightly above.10, an indication of slight heterogeneity. Moderation tests indicated that very little heterogeneity was attributable to the order in which the tasks were performed or whether the tasks were administered in lab versus online. Exploratory comparisons revealed little heterogeneity between Western, educated, industrialized, rich, and democratic (WEIRD) cultures and less WEIRD cultures (i.e., cultures with relatively high and low WEIRDness scores, respectively). Cumulatively, variability in the observed effect sizes was attributable more to the effect being studied than to the sample or setting in which it was studied.
