Muslim and Arab individuals are discriminated against in almost all domains. Recently, there has been a focus on examining the treatment of these groups in the work setting. Despite the great number of primary studies examining this issue, there has not yet been a quantitative review of the research literature. To fill this gap, this meta-analysis examined the presence and magnitude of hiring discrimination against Muslim and Arab individuals. Using 46 independent effect sizes from 26 sources, we found evidence of discrimination against Muslim and Arab people in employment judgments, behaviors, and decisions across multiple countries. Moderator analyses revealed that discrimination is stronger in field settings, when actual employment decisions are made, and when experimental studies used "Arab" (vs. "Muslim") targets. However, primary studies provide inconsistent and inaccurate distinctions between Arabs and Muslims, therefore future work should be cautious in categorizing the exact aspect of identity being studied.
