Facts Change Minds—Until Partisans Feel Attacked

What Jin Woo Kim Asks

Jin Woo Kim (BJPS) investigates when and why partisans reject political evidence that contradicts their side. The study tests whether resistance to uncongenial information is a stable feature of partisan cognition or whether it depends on the emotional context in which information is received.

How the Study Works

The article reports two preregistered survey experiments that expose partisans to the same pieces of congenial and uncongenial evidence. In both experiments, subjects were randomly assigned to conditions that either left affective context neutral or induced a feeling of adversarial threat (making politics feel hostile or conflictual). The design measures changes in agreement with the evidence after exposure to assess persuasion versus dismissal.

Key Findings

• When no affective triggers were present, partisans were persuaded by both congenial and uncongenial information: people updated in response to factual claims even if those claims contradicted their prior partisan orientation.
• When participants were randomly induced to feel adversarial, they became more likely to dismiss uncongenial evidence and—crucially—ended up more disagreeing with the target claims after considering the same information.
• These contrasts show that motivated reasoning depends on emotional context: partisan resistance emerges more clearly under conditions that provoke adversarial affect.

Why This Matters

• The results identify a specific condition—adversarial affect—that provokes resistance to political persuasion, helping reconcile conflicting findings in the literature on motivated reasoning.
• The experiments demonstrate partisan-motivated reasoning more clearly than studies that do not manipulate affective context.
• The findings highlight the downstream consequences of elite-level political tone: hostile public discourse may reduce citizens' willingness to accept corrective or challenging information, undermining evidence-based opinion formation.

Implications for Scholars and Practitioners

These experiments suggest that improving the quality and tone of political discourse could increase citizens' responsiveness to factual information. The research points to affective polarization and elite rhetoric as crucial levers for whether evidence changes minds or entrenches disagreement.
