Question: if the main take-away of your book is “It is women’s behaviour and preferences that will need to change”, are you really a “well-meaning man”?

Very interesting question. Sadly, in psychology and mental health research we cannot entertain such thought experiments much, because we rarely meet the ‘used good data bar’.
If we look back at old science papers, what percentage drew incorrect conclusions? I don't mean how many had data that turned out to be flawed, but how many used good data to claim something that later turned out to be Wrong? I suspect the percentage is quite high but it would be hard to check.

I moved from posting to Bluesky to LinkedIn a while ago even if I hate the latter with all my heart, because, despite the hype about Bluesky, it seemed most conversation in the fields that interested me was there. But now it seems Bluesky is cool again.

I use CRediT even when the journal doesn’t specifically ask for it and even when the journal has their own check-box questionnaire in the submission system because I am *that* cool (no, it’s because it’s important)
10 years since CRediT was introduced, >20% adoption (of full text in Dimensions). Now, we need to build on this to comprehensively integrate CRediT in metadata and make sure the taxonomy evolves to remain fit for purpose. doi.org/10.1038/d415...

There simply is no need about AI-based diagnosis of any mental disorder. Criticism of these nonsense papers should not obviate a more fundamental discussions. We do not need engineers and AI to profile mental disorders, no matter how they do it and write it up.
Had to see for myself. Shared by @smutclyde.bsky.social, published in Nature Scientific Reports (like PLOS One, peer-reviewed [!] for soundness, not importance). The article is about AI-based autism diagnosis. Article processing charge: $2690. AI slop science: priceless

Why does every target trial emulation study have to include a bit that says "this shows how great target trial emulation is. RCTs are non-generalisable and expensive"? Imagine if every RCT said "this shows how great RCTs are. We did not have to rely on strong, untestable assumptions".
