Polarisation curve for the US Congress between 2011 and 2016, peaking around the release of the Clean Power Plan in the summer of 2015.

Polarisation curve for the US Congress between 2011 and 2016, peaking around the release of the Clean Power Plan in the summer of 2015.

In this new paper with @fisherdanar.bsky.social in Politics and Governance, we distinguish intrinsic and instrumental polarisation and analyse polarisation curves and phases in US climate politics. We also present new methods for discourse networks. doi.org/10.17645/pag... @cogitatiopag.bsky.social

Three stages with ideal-type network structures. The first stage shows two separate clusters of solution-oriented actors and actors with vested interests. The second stage shows a disaggregation into multiple clusters of each kind. The third stage shows emerging advocacy coalitions as clusters cutting across the two types of actors.

French scientist denied US entry after phone messages critical of Trump found France’s research minister said the scientist was traveling to Houston for a conference when his phone was searched

After the US denied entry to a French academic en route to a conference recently (and some other cases of detained German citizens), I have decided not to attend US conferences until further notice. It's too much hassle and money to risk being detained. Sorry. www.theguardian.com/us-news/2025...

Ground-truthing political elites in the public sphere: Measuring the arena effects of elite opinion - Tim Henrichsen, Philip Leifeld, Lorien Jasny, Iain Weaver, Dana R. Fisher, 2025 Political elites express their ideological positions on contentious issues across various arenas in the public sphere. Social science research often relies on d...

How do political actors adjust their messaging to different communication arenas? This paper finds ideological communication on Twitter is most left-leaning, Congressional testimony is most right-leaning & surveys are in the middle, enhancing our understanding of systematic bias in data sources.
