The politics of seeking and avoiding discourse in parliament

Abstract When do politicians debate each other in parliament, and when do they prefer to avoid discourse? While existing research has shown MPs to unilaterally leverage the dialogical nature of legislative debates to their advantage, the circumstances facilitating actual discursive interaction have so far received less attention. We introduce a new framework to study the emergence of discourse in political debates. Applying this framework, we expect ideological differences and government–opposition dynamics to shape politicians' choices about seeking or avoiding discourse. To test these hypotheses, we draw on an original dataset of all 14,595 attempted and successful interventions ( Zwischenfragen ) – extraordinary, voluntary discursive exchanges between speakers and MPs in the audience – in the German Bundestag (1990–2020), extracted using an annotation pipeline developed specifically for this study. We find that MPs separated by diverging preferences seek discourse with one another more often than their ideologically aligned counterparts. At the same time, these exact attempts do less frequently result in discursive interactions. When considering government–opposition dynamics in this process, we observe very similar patterns: Attempts to initiate discourse are particularly common among opposition MPs facing government speakers, and we find tentative evidence suggesting that government actors are most likely to avoid these invitations to discursive interaction. Our findings have important implications for our understanding of elite behaviour in public environments.
