The current state of the art is using item level data directly. Sadly it depends on the chosen IRT model, and power is still low. Also, it cannot detect AxC if the estimated C is zero, which is ofc a problem since AxC acts very much like A

I looked through all my bookmarks, sadly I failed to find it. However I'm 99% sure the statement was made by Mcardle or Horn.
On the bright side I managed to recover this lost article my Mcardle, where he has to admit that Horn was right all along, g is not real.

In the paid article he cites a different article(that's why he messed up the publication date).
But of course this article also notes that it is not identified.

Only the shark and crocodil one afaik(but they are among the most popular). The rest are either random words that gpt made up, or are fairly innocent. Some are not even Italian, but only a few know. This implies that thankfully they don't translate them, so are not affected that much.

Crem used to claim on Reddit that "he was actually in contact with (dutch) researchers, and they agree with him but they won't admit it in public"

Turns out that "being in contact" meant that he sent out an email to some of them. And they don't agree with him. And he is horrible at using R.

It gets worse
