Ecco.
Von der Leyen backs regime change in Iran, contradicting the position of EU national governments, and endorsing Merz’s supportive stance.
2 issues:
- she has no authority to say/do that
- she is not even asking the US something in return (Ukraine’s support)

There are so many good things about this by-election: a progressive candidate who seems genuinely nice won on a platform of unity and compassion, Matt Goodwin was sent packing, Labour lost badly, the Tories reached levels of insignificance previously unknown. Just so good!

Starmer portraying the Greens as manic leftist extremists is not going to wash with much of the progressive voters that Labour is losing at an increasing rate.
Much of Labour's core vote view the Greens at worst as a rather harmless group of eccentrics rather than the second coming of Mao Tse Tung.

Ofc, this point is considered in (A) of the paper, that leads to the second point:
bsky.app/profile/matt...
That is why it can be useful to consider HOIs and simplices a priori -not merely as representational choices, but as assumptions about the generative process.
Of course, one can encode everything in a dynamic graph. But when group interactions are primitive at the generative level, the resulting adjacency structure is not equivalent to one generated purely through independent pairwise events.
My point was slightly different, focusing more on generative assumptions than on the representation.
If higher-order interactions are included in the generative mechanism itself - interactions occur as group events - this alters the statistics of the integrated 1-skeleton in nontrivial ways.
So perhaps the deeper question is not whether higher-order interactions “exist” in a strict sense.
It is whether modelling interactions as collective events helps us better understand the processes we are interested in.
For instance, complex contagion in the Watts–Dodds framework can be demanding, while simplicial approaches such as Simplagion are easier to analyse.
The issue is not which representation is more “true,” but which is more useful.
In some cases, simplicial formulations make certain mechanisms analytically clearer or more tractable. In others, pairwise formulations suffice.
This becomes a pragmatic rather than an ontological debate.
But the same applies to pairwise networks.
Edges do not “exist” in any pure ontological sense either. They are representations - abstractions that help us organize observed interactions.
At that point, the question shifts.
Ps. There may also be a philosophical angle here.
The article cautions against inferring ontology from formalism: the fact that certain empirical phenomena are captured by hypergraph or simplicial models does not, by itself, imply that such higher-order structures “exist.”

The real question, beyond the mathematics, is:
Is a group interaction substantively different from its pairwise representation?
HOIs are still a relatively young field.
It will take time to fully connect current formal results with what psychology and sociology of group dynamics have been showing for decades.
That said, the situation is nuanced.
Group interaction in temporal networks can also be interpreted as a closure mechanism. And in toy models, simplicial representations often function as mathematical devices that make analysis easier.
Intuitively: seeing friends separately is not the same as going out as a group.
In temporal settings, the difference between a simplicial interaction and a sequence of pairwise ones appears much sharper.
Simultaneity matters.
