The First Post-Reality Political Campaign Hungary’s Viktor Orbán is waging cognitive warfare on a new scale.

Viktor Orban is waging cognitive warfare on a scale no one else has tried before. "Emotions are high because the stakes are high. If he succeeds, he will once again blaze a path that others will follow. And if he loses, an era comes to an end."

V-Dem v.16 is now released, w. updated scores for 2025.

Most countries remain stable from 2024, but some clear improvements (on diff’t democracy indices), incl. S. Korea, Sri Lanka & Mauritius.

Largest declines came, by far, in the US.

This figure shows 10-yr changes on the Liberal Dem. index.

Europe’s Ukraine consensus still holds – but the far right is splitting over Russia Europe's mainstream parties remain firmly supportive of Ukraine, but divisions over Russia are becoming increasingly prominent among the populist radical right.

Voting patterns in the European Parliament suggest mainstream parties remain firmly supportive of Ukraine.

But divisions over Russia are increasingly pronounced among the populist radical right.

The political effects of X's feed algorithm

Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects.
Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right.

Moving from chronological feed to the algorithmic feed also increases engagement.

This is one of the most concerning papers I’ve read in awhile.

Transatlantic TikTok propaganda and the end of localised populism  TikTok deportation propaganda is fast becoming the new border wall. States, platforms and algorithms are fusing into a single machine. This, says Mimi Mihăilescu is turning deportation into bingeable content, burying resistance in the feed, and replacing physical walls with algorithmic control. Local populism dies and global spectacle rules

Immunising the Venice Commission Against Autocratic Contamination

"It is at the very least inconsistent to warn against rule of law regression and violations while failing to police one’s own membership. We are where we are because too many in senior positions who had and have the power to act have failed to do so."

Stacked bar chart showing that a declining share of Americans, especially Republicans, say they support all or most of President Donald Trump's plans and policies. The chart is based on Pew Research Center surveys of U.S. adults conducted in February 2025 and January 2026.

A narrow majority of Republicans (56%) now say they support all or most of Donald Trump's plans and policies, down from two-thirds (67%) in February 2025. It's one of several measures of a loosening GOP support for Trump in a new @pewresearch.org survey: www.pewresearch.org/politics/202...

Political scientists see non-violent resistance as much more effective--and it's not just from aggregate statistics. Rather, it's the way that peaceful resistance undermines the state's repressive capacities.

This op-ed by Berkeley prof @owasow.bsky.social explains this logic 🎯.

Give it a read!

Trump wants our attention. Let’s stop falling for his geopolitical clickbait | Catherine De Vries Whether he’s targeting Greenland, tariffs or Iran, Trump’s agenda is to distract – because a Europe that is always reacting is never planning, says political scientist Catherine De Vries

Today in @theguardian.com, I argue that Donald Trump’s foreign-policy playbook is increasingly about attention capture, or what I call geopolitical clickbait.

Plus I outline why this matters for Europe & what to do about it.
