Influence functions are for problems where you have a mismatch between the loss of the target parameter you care about and the loss of the nuisance function you must fit to get the target parameter.

It's important to internalize that the intellectual world lives in the attention economy, like eveything else.

Just like "content creators" on social platforms think hard about capturing and keeping attention, so do intellectuals and academics. Clarity and rigor is a part of that.

No one has time, energy, (or crayons, as the saying goes) for half-baked ramblings on a blog or forum somewhere.

If you think you can beat the American __ Association over a long run average, that's great news for you! That means free money!

Being right is super valuable, and you should monetize it immediately.

Lots of Bayes fans, but can't seem to define what Bayes is.

Since Bayes theorem is a reformulation of the chain rule, anything that is probabilistic "uses Bayes theorem" somewhere, including all frequentist methods.

Frequentists quantify uncertainty also, via confidence sets, and other ways.

Continuous updating has to do with "online learning algorithms," not Bayes.

Bayes is when the target of inference is a posterior distribution. Bonus Bayes points: you don't care about frequentist properties like consistency of the estimator.

Does your argument fail for https://en.wikipedia.org/wiki/Goldbach%27s_weak_conjecture?

If so, can you explain why? If not, it seems your argument is no good, as a good proof of this (weaker) claim exists.

Not that you asked my advice, but I would stay away from number theory unless you get a lot of training.

For the benefit of other readers: this post is confused.

Specifically on this (although possibly also on other stuff): (a) causal and statistical DAGs are fundamentally not the same kind of object, and (b) no practical decision theory used by anyone includes the agent inside the DAG in the way this post describes.

---

"So *if* the EDT agent can find a causal structure that reflects their (statistical) beliefs about the world, then they will end up making the same decision as a CDT agent who believes in the same causal structure."

A -> B -> C and A <- B <- C reflect the same statistical beliefs about the world.

If you think it's a hard bet to win, you are saying you agree that nothing bad will happen. So why worry?

Wanna bet some money that nothing bad will come of any of this on the timescales you are worried about?
