Which restrictions do you have in mind?

why may chatgpt give better answers than Cursor, even when i set gpt as the engine for the latter and it has the whole project as background instead of just one script?

First time Iโ€™ve seen the rabbit/bird illusion with an actual photo. Took me just a half second to process the word in all capsโ€ฆ

I don't think it is fair to characterize this as a "both sides' situation. I tried *for months* to engage in open dialogue

They lacked the common-decency to reply to the emails asking for the paper, after I answered emails from them for years

If they write a reply, happy to have a follow-up post

2) Clintin & Richard say we claim to test if p-curve is skewed but we don't do that

I see this as semantics.

Indeed. We don't test whether *observed* p-values are skewed.
Rather. We test whether data generator produces skewed ps

e.g. p=.0001, p=.0002 are not skewed but suggest skewed generator

They say, I think 2 things that fall in this category.

1 ) Clintin & Richard say "evidential value" is not a stats concept.

I agree, but this is because we invented it. We needed a term for "significant after accounting for p-hacking", It didn't exist, so we came up with evidential value.

A feature i really like is custom intro and "outro" skipping so you skip the yada yada and get to the actual episode

Been using two monitors for many, many years.
Just tried a single wide (curved 34") monitor instead.

It's slightly less wide total a bit taller.
It's way better.

Looing at center of screen instead of to the side, no dead zone in the middle.

While in many respects the situation is dire I think itโ€™s worth pointing out that there are multiple scientific ecosystems. Being scandalized shows that we normally live in a better functioning, privileged part of the scientific community.

With their approach this seems easy actually. What we call 'treated stimulus design'. Draw one man, black or white, algorithmically generate the twin of the other race. And There is still room for stratified sampling

I dont think thats a realistic concern if you just browse the home page. It's a funny headline, but not super diagnostic

Fellow European researchers, if at all in your power, try to get your school to consider late applicants who were admitted to US programs.

Hearing from many cases of admitted to top US schools who last minute realize they won't be allowed in the country.

Hm, Israel and the aid agency deny the shooting.
We can't adjudicate the truth here, but if the journalists don't tell you that it's disputed, I think you should not trust the journalists.

I think the best comparison would be something like
X1: how interesting is the (non)finding?
X2: how credible is the finding?

Compare x1*x2 across formats

Know of any attempts to do that?

(though even that is just a correlation)

yeah, arguably "" is the right character.

we just need to allow our "printed" media (academic paper pdfs) to tolerate not including https:// , papers can be filled with them and it is cluttery.

Maybe in academic journals we could adopt a convention.
