I’d add the pragmatist guide to relationships (has material on seeking as well as on maintaining relationships) I read like half the book (the parts remotely relevant to me (the book has ~660 pages)) and is very much written from a more selfish livehacking/”munchkinism”/economist (markets and contracts) kind of perspective, which I found entertaining, but which might be off-putting for some. The authors also know and seem to practice their Bayesian epistemology, and the book held up pretty well to online spot checks, and asking people. I still felt like sometimes the authors didn’t add enough uncertainty disclaimers around their theories about humans, but it’s not like I wouldn’t have similar complaints about some lw posts. and
The pragmatist guide to sexuality(lots of data on what people’s sexuality is actually like! 100% recommended (though maybe just skip the authors interpretations and look at the tables))
I remember the magazine I read as a kid (Geolino) had a section like this (something like 7 news stories from around the World and one is wrong). It’s german only, though I’d guess a similar thing to exist in english media?
