The first question is that I don't see why many of the things you listed are bad.
Why is a high divorce rate bad? Why a lower age of the first sexual encounter (compared to what, by the way?) is bad? Why having many lifetime partners is bad?
The second question is how do you distinguish correlation and causation -- I'm looking at the male testosterone level.
As an aside, are you aware of Yvain's Anti-Reactionary FAQ?
People want to tell everything instead of telling the best 15 words. They want to learn everything instead of the best 15 words. In this thread, instead post the best 15-words from a book you've read recently (or anything else). It has to stand on its own. It's not a summary, the whole value needs to be contained in those words.
I'll start in the comments below.
(Voted by the Schelling study group as the best exercise of the meeting.)
