Personality and political news consumption online A comparison between self-reports and webtracking data

Research has explored the links between personality and political news consumption, resulting in mixed results that vary across platforms. One potential reason for these inconclusive patterns might be that previous work has exclusively relied on self-reported measures of political news consumption. Considering that personality has been linked to biased response behavior in the past, we investigate to what extent the relationship is affected by potential measurement errors associated with different capturing methods. To do so, we introduce an innovative measurement technique capturing actual internet use through webtracking. While we do not find strong evidence that personality is systematically related to over- or underestimating one's political news consumption, the comparison between the behavioral webtracking measure and self-reported news consumption nevertheless reveals significant differences: notably, openness is positively associated with self-reported online news consumption, but this relationship does not hold in the webtracking data. Instead, when using behavioral measures, neuroticism is a better predictor of political news consumption – an association not observed in the self-reported data. Our insights refine our understanding of the interplay between personality and online political news consumption and enhance the broader discourse on survey response behaviors linked to personality.
