A new study published on arXiv explores the relationship between evidence-based communication and legislative effectiveness among members of the US Congress. Researchers developed an Evidence-Minus-Intuition (EMI) score to measure the prevalence of evidence-oriented versus intuition-oriented language in congressional speeches and on Twitter. The findings indicate that more ideologically extreme members tend to use less evidence-based language on the congressional floor, and this orientation is consistent across platforms, though generally lower on Twitter. Crucially, the study found a positive association between using more evidence-oriented language in congressional speeches and higher individual legislative effectiveness, even after controlling for various factors like ideology and communication volume.
