Many recent applications of the “Unexpected Event during Survey Design” (UESD) analyze single cases of frequently occurring events. In this research note, I question the generalizability of research findings obtained this way and demonstrate the empirical benefits of the “Multiple Unexpected Events during Survey Design” (MUESD). I conduct 15 large-scale replications (total N = 101,940) of a new UESD analyzing the effects of Mediterranean shipwrecks on immigration attitudes. Previous research suggests that such events drastically reduce anti-immigration attitudes among the European public, presumably through an empathy-based mechanism. However, after 15 of the most lethal shipwrecks since 2013, anti-immigration attitudes were reduced in only one case of exceptionally high salience and to a much lesser degree than originally found.
