<p>Americans are increasingly unwilling to talk about politics with out-partisans. One potential barrier to such cross-cutting partisan conversations may be partisans’ tendency to stereotype out-partisans as lacking the deliberative traits necessary to have a productive conversation (i.e., <i>partisan deliberative bias</i>). Here, three studies examine the presence of partisan deliberative bias, its relationship to cross-cutting political talk, and potential pathways to reducing partisan deliberative bias. Study 1 (two-wave panel; Wave-2 <i>N</i> = 695) provides evidence that partisans perceive out-partisans possess less deliberative traits than in-partisans and these perceptions are related to reduced cross-cutting political talk (at Time 2). Study 2 (experimental; <i>N</i> = 417) provides evidence that exposing individuals to more examples of out-partisans who display deliberative traits (vs. anti-deliberative traits) leads to increased perceptions that out-partisans possess deliberative traits, which is associated with greater willingness to engage in a political conversation. Study 3 (experimental; <i>N</i> = 825) provides evidence that a deliberative bias-correcting intervention can reduce stereotypes about out-party members’ deliberative traits. Further, findings from an alternative model that includes in-group favoritism suggest that perceptions of deliberative traits are significantly related to cross-cutting political talk even when accounting for affective polarization. Findings across all three studies are similar for Republican and Democratic participants. Taken holistically, these results highlight the prevalence of partisan deliberative bias, suggest that such bias reduces cross-cutting conversations, and provide preliminary evidence for the effectiveness of interventions to address this bias.</p>
