Why do some self-regulated learning interventions seem to benefit less competent students more than their competent peers, but others seem to benefit only the already competent students? Well...(1/2)

My wife was sexually harassed by Miles Hewstone as a phd student. He was still asked to review her (and other women he harassed) for jobs and promotions. This is so fucked up.
Thankfully, she and many other women testified against him and something was finally done. This is her take on his case:

this is genuine psychological warfare and it seems to happen to every professional woman at some point:
At some point during my PhD, a senior male colleague told me that the only reason another senior male colleague was interested in my research was to get into my pants. Double whammy: apart from harassment fears, that made me think that my research was garbage.

LLMs are now widely used in social science as stand-ins for humans—assuming they can produce realistic, human-like text
But... can they? We don’t actually know.
In our new study, we develop a Computational Turing Test.

There's not much in the blog post I disagree with, but I do want to clarify why a request for vetting by statisticians is not an invitation to "arguments from authority". When we "vet" something, we do more than ask someone what they think. Obviously if we just asked for a statistician's 1/x
