Rationality might not have a lot of practical value, precisely because things that had such value are already well-engineered by evolution and culture. But it still advances your understanding of the world and yourself a lot, and I personally find that one of my few terminal values.
Incidentally, rationality might imply that Starcraft is a kind of trojan that exploits our reward circuits, and if we want to maximize our values (as opposed to our pleasure), we are well-advised to take a stance against this exploitation.
My personal experience is that I had most of what enables me to be epistemically rational from childhood (so probably genetic), but that the exposure to behavioral economics, science and other rationality-adjacent memes early in my life significantly boosted that genetic seed.
Another personal observation: I have never felt someone I know has improved their rationality. Though I also don’t know almost anyone who even cares about becoming more rational.
I think they do; Consider The League. It’s a somewhat exclusive dating app that does provide advice on your profile.
An app that has a more attractive community is itself a more attractive app.
A major missing piece might be that in the ancestral environment, sexuality and the social sphere were quite different from the modern day. Specifically, (the following points are mere speculation on my part.)
Aside from these, I think you have not produced much evidence that people are bad at dating. Most of the examples you have provided seem to me to be the kind of things that thee public is generally bad at. (Like, the public doesn’t use “evidence-based” books on most any subject.)
I rate books’ perceived potential from 0 to 10 (I actually just label anything below 7 as bad as I’ll never read those). I use Goodreads/Amazon’s ratings/reviews, the source I used to find the book, its Goodreads summary, and its authors to estimate its relevance to my goals, its quality in achieving its purported aim, and its relative quality in the memesphere it tries to elucidate. I use Goodreads exclusive shelves to label each book’s potential and also shelf it under what it teaches. I then browse my Goodreads’ shelves when I’m out of books. This whole approach doesn’t work very efficiently though, as I have trouble assessing books’ qualities and my own priorities.
What’s the curl command to access this via the API?
The main use I have in mind, though, is just seeing the latest edit date to know how up-to-date the post is (or how well-maintained, in the case of repository-style posts.)
I already use Voice Dream, and I love it! But human voice is still better quality.
My HDL is 29, so I’m rather afraid of messing my lipids further.
