This study explores how disgust and anxiety influence learning during political threats.

• Context: Research on emotions in political engagement often focuses solely on anxiety, neglecting the distinct role of disgust.

• Methodology: Experiments manipulated perceptions of infectious disease outbreaks to measure emotional responses.

• Findings: Disgust led people to avoid crucial information and additional resources about a threat.

• Implications: These results highlight how basic emotions like disgust can reduce engagement precisely when they are most relevant or necessary for effective response.

The research reveals that while both emotions react naturally to threats, disgust operates differently from anxiety in terms of political learning. By creating conditions mimicking infectious disease outbreaks, the experiments demonstrate that disgust—a fundamental emotion guiding avoidance of contamination—impairs information processing during critical situations unlike its counterpart anxiety does.
