MSF condemns this attack and calls for protection of civilians and health facilities.

Strikes near hospitals spread fear and deter lifesaving care. MSF is deploying a mass-casualty kit and continuing support.

Civilians cannot be collateral damage.

Or without the relabelling:

First choice -> M <- Query

Where all three nodes have domain {L, M, R} and you make inferences on Query given your choice and Monty’s reaction, knowing Monty’s rule

Formally just like the usual X -> Y <- Q

So realize this is just back to the top nodes of your graph

Realise this can just be thought of as learning about a parent from a child :

Query -> M

Where Query in {A, B, C} and M in {B, C}

No collision

Hi will; fwiw here's a version with a three node DAG, all nodes binary that captures the core I think?

A -> B -> M <- A

Implemented in CausalQueries below

M is a collider and lets you learn about the joint distribution of A and B

(Causal interpretation of first link questionable maybe)

Fun fact: my dissertation was called "Wars of Choice" (became Leaders at War: How Presidents Shape Military Interventions @cornellupress.bsky.social). Tl;dr: they rarely go well. 1/ www.cornellpress.cornell.edu/book/9780801...

Glad to see this getting international attention: the culture minister’s ham-fisted move against independent bookstores; another worrying sign of the German government drifting away from liberal principles

Horrific to see, again, the treatment of Lebanon and disgusted to see this reckless use of evacuation orders, this normalization of the abuse and traumatization of civilian populations, and the tolerance for this horror all around

for majority rule that's pretty much right; there's work connecting e.g. dimensionality to the Nakamura number e.g in Austen Smith and Banks (the piece with Laver is for non standard prefs)

but again even if there's sometimes a little hope in d>2, the core hasn't done the work we hoped of it in d=1
