No, this was a dysgenics paper with MCV + item data that fixed (most of) the issues raised by
@JelteWicherts. -
Fascinating. I would read it. I read
@JelteWicherts's paper on the topic. -
I'll have it sent to you. But TL;DR version is that item-level MCV analyses requires a few corrections to the method used for test-level data, and if one doesn't apply these, one gets uninterpretable results depending on relationship between difficulty and loading.

We applied the corrections as a test case to a large vocabulary dataset (75 items) with fertility data. Found that the usual results hold: selection appears to be on general factor variance.
