Summary	The Anti-Immigrant Prejudice Scale, developed by Thomas Pettigrew and Roel Meertens in 1995, measures prejudice toward immigrants along two dimensions: blatant prejudice, which is hot, close, and direct, expressing open rejection and perceived threat, and subtle prejudice, which is cool, distant, and indirect, expressing defense of traditional values, denial of positive emotion, and exaggeration of cultural difference. Built from national samples across western Europe, the scale captures the modern, socially acceptable face of anti-immigrant attitudes that overt-prejudice items miss, while its two-factor structure remains the subject of ongoing psychometric debate.	The Intergroup Threat Scale operationalizes intergroup (originally integrated) threat theory (Stephan & Stephan), which holds that prejudice toward an out-group arises from perceived realistic threats (to the in-group's resources, power, or welfare) and symbolic threats (to its values, beliefs, and worldview). It is a self-report measure widely used to explain attitudes toward immigrants and other out-groups in political psychology.
