Procedure Matters: The Distinct Attitudinal Feedback Effects of Immigration Policy

Natives who dislike immigrants prefer restrictive immigration policies, but do those policies deepen or alleviate anti-immigrant attitudes? Existing theories have offered mixed predictions. Restrictions imposed on immigrants may harden intergroup boundaries and thus deepen hostilities. However, they may also soften attitudes by addressing the economic and identity concerns of natives. Using a conjoint experiment conducted in Hong Kong, I test the multidimensional effects of immigration policies on natives’ attitudes toward highly skilled immigrants. I find that restrictive measures consistently generate more positive attitudes. Strikingly, this effect cannot be fully accounted for by major theoretical explanations, including labor market competition, social identity, and welfare attitudes. Preexisting policy preferences do not condition the effect either. These findings point to the importance of attitudinal policy feedback beyond traditional accounts of immigration attitudes. In-depth qualitative interviews identify two novel causal mechanisms: moralizing and quality assurance effects.
