Epistemic orientation in parliamentary discourse is associated with deliberative democracy
arXiv · 2604.19699
The Takeaway
The linguistic style of parliamentary debate is a quantifiable indicator of a country's democratic health. Shifts toward facts and evidence over intuition and feelings lead to better deliberative outcomes and more effective law implementation. Many people assume that political theater is just for show and has no real impact on governance. This study proves that the way politicians talk to each other directly affects how well the government functions for its citizens. Choosing leaders who prioritize evidence can lead to a tangible improvement in a nation's stability.
From the abstract
The pursuit of truth is central to democratic deliberation and governance, yet political discourse reflects varying epistemic orientations, ranging from evidence-based reasoning grounded in verifiable information to intuition-based reasoning rooted in beliefs and subjective interpretation. We introduce a scalable approach to measure epistemic orientation using the Evidence--Minus--Intuition (EMI) score, derived from large language model (LLM) ratings and embedding-based semantic similarity.
