This is actually what I most wanted to highlight. I remember hearing a Labour MP argue that politics was ultimately just "a game of competitive storytelling", and then reflecting on just how disturbing the implications for democracy, accountability, and policymaking would be if that were wholly true

How do institutions communicate about #migration?

With @jamesrdennison.bsky.social & @mcduarte.bsky.social, we built a database of migration communication campaigns in Europe.

We’re expanding it now. Do you know a campaign? Please take this 1-min survey.

The bad thing about this happening in a Labour seat is it gives the press a big excuse to ignore the fact Reform’s strategy is failing. They’ve now lost 3 in a row in 3 different countries to 3 different parties because their plan of coming through a split vote isn’t working. Their vote is too low

Violent and non-violent death tolls for the Gaza conflict: new primary evidence from a population-representative field survey This first independent population survey of mortality in the Gaza Strip shows that violent deaths have substantially exceeded official figures whereas the demographic composition of casualties aligns ...

New evidence estimates that the Israeli military directly killed 75200 Gazans between Oct '23 and Jan '25. 22800 children were killed. Children, women, and the elderly were 56% of the killed. Non-violent deaths were also far higher than pre-"war". www.thelancet.com/journals/lan...

Does moving often as a child weaken social capital later in life?

From context to congruence: Immigration salience and voter socialization
Published online by Cambridge University Press:  26 January 2026
Leonardo Carella and Francesco Raffaelli
This paper considers how issue salience environments affect long-term patterns of political choice via processes of political socialization. Drawing on the well-known β€˜impressionable years’ hypothesis, we theorize that voters who grew up in high-immigration salience contexts subsequently exhibit higher levels of voter-party agreement on immigration (issue congruence). We find support for this hypothesis from two studies, which leverage cross-sectional variation within cohorts in exposure to immigration salience in voters’ formative years. The first employs congruence data from a survey of 10 European countries, linked to historical salience data from the Comparative Manifesto Project. The second is a within-country study, measuring salience and congruence from two long-running German public opinion survey series. The analysis suggests that growing up at times when immigration is high on the political agenda can have long-term consequences for the relationship between voters’ preferences on that issue and their political choices, shedding light on the mechanism behind β€˜generational realignment’.

Really happy this work with @fraraffaelli.bsky.social found a home at EJPR. We show that growing up at times of high salience of immigration produces cohorts of voters who are more likely to vote for parties that they agree with specifically on immigration.

Robert Jenrick sacked by Tories for 'plotting to defect' - live updates Reform UK leader Nigel Farage says while no deal has been signed, he had conversations with Jenrick and plans to call him today.

Surely, surely, this will allow most Reform supporters finally to wake up to the fact that they are backing the very same self-serving, corrupt, venal right wing grifters they’ve been trying to reject since the last election?

On the Robert Jenrick defection psychodrama:

His team have been plotting for months, so it was going to blow up at some point!

Most of my Tory sources agree he decided to defect after months of losing momentum in his bid to topple Badenoch as leader, as she started to improve

The worst, most dishonest prime minister we’ve ever had, rocks back and forth in his Daily Mail cubbyhole spewing out idiotic bilge to kid himself that he and his disastrous Brexit weren’t an almighty national fuck-up.
A deeply pathetic threat from an abject failure of a man.
