Muslim Americans face frequent public and governmental discrimination, yet few interventions have been rigorously tested to reduce that prejudice. This study tests whether providing corrective information about common misperceptions—specifically that Muslim Americans are unusually foreign, threatening, or disloyal—can improve attitudes toward the group.

📋 How the Experiment Tested Corrections

• A randomized informational treatment presented corrective facts aimed at three misperceptions: foreignness, threat, and disloyalty.
• Attitudinal measures and policy preferences were collected to evaluate overall effects and heterogenous effects across subgroups with higher predispositions to prejudice.

📊 Main Results

• The informational treatment produced modest improvements in general attitudes toward Muslim Americans.
• Some subgroups predisposed to prejudice showed attitudinal gains as well.
• The treatment had little impact on policy views tied to Muslim Americans.
• Effects showed vulnerability to social desirability bias—some positive responses may reflect respondents' desire to appear non-prejudiced rather than deep attitude change.
• Effects were also sensitive to priming: reminders of terrorism threats weakened the treatment's impact.

📌 Why It Matters

• Corrective information can reduce prejudice on the margins but is limited in scope and durability.
• Such interventions appear most effective in less politicized contexts and are unlikely on their own to shift policy preferences or withstand threat-based priming.
• The findings imply that information campaigns addressing misperceptions can be a useful component of broader strategies to reduce anti-Muslim prejudice, but expectations about their potency should be modest.
