Following the October 7th Hamas attacks on Israel, antisemitic incidents surged on college campuses, ranging from overt hostility to subtle prejudice. Using the microaggression framework, we developed a taxonomy to categorize antisemitic experiences. We found that among participants from North American universities, subtle incidents of antisemitism were more frequent than overt incidents, yet both types of incidents were associated with negative psychological and institutional outcomes. This study underscores the necessity of recognizing both overt and subtle antisemitic experiences. The taxonomy is useful for identifying, teaching about, and addressing antisemitic experiences in academic settings.
