As this is a working paper, comments and any feedback are always welcome.

Wishing to maintain hierarchies through law as well as violently is significantly increased by the ruling. Additionally, anti-immigrant parties (Conservatives UKIP and Reform) indirectly receive an increase of voting intentions by around 6 percentage points.

I find that Britons surveyed after the ruling become significantly more socially dominant compared to the ones surveyed before the ruling. The effect is primarily driven by White Britons.

It is the Supreme Court decision on the Rwanda scheme that I use as my quasi-experimental treatment. I use an unexpected event during survey design to test how the ruling influenced people's hierarchical values measured as social dominance orientation (SDO).

I argue in the paper that the Supreme Court ruling should threaten the British public due to the Supreme Court defending the rights of a group that is perceived to be threatening.

The Rwanda Scheme was the controversial treaty between Rwanda and the UK that allowed Britain to send its asylum seekers to Rwanda to have their asylum request processed there. The UK Supreme Court decided on November 15, 2023 that this scheme is unconstitutional due to human rights concerns.

The main takeaway from our article is: a rally 'round the European flag occured after the full-scale Russian invasion of Ukraine. This is best explained by Europeans seeing the security benefits of a united Europe rather than emotional attachment to the European project.

As with many UESD applications, the effect is short-lived, lasting for around 3 weeks after the start of the full-scale invasion. However, we find that the support for a united EU jumps up again after the Ukrainian victory in the battle of Kyiv, reflecting EU reliability as an ally to Ukraine.

In academic terms: this provides support for a functionalist understanding of EU integration as opposed to a post-functionalist understanding. That is to say, considerations about the benefits of Europe, rather than emotional attachment, drive this rally 'round the flag effect.

Additionally, we find that the effect of the Russian invasion on EU integration attitudes is stronger for those who have higher political interest, but not for those who are emotionally attached to Europe.

Using @ess-survey.bsky.social data and an unexpected event during survey design we find causal evidence that the Russian invasion increased European support for EU integration. The effect is present for individuals from EU and non-EU countries alike.
