Saturday assorted links

1. Model this.

2. A bunch of claims about nobles, genetics, and violence.

3. New results on interpretability.  And much more detail.  Potentially very good news.  One interpretation.  Some are becoming less pessimistic.

4. Arnold Kling on the trouble with books.  Remedies will come!

5. “We show that the high level of rural income mobility is principally driven by boys of rural-origin, who are more likely than their urban peers to grow up in communities with a predominance of two-parent households.”

6. Might desalinated water ever be cheaper?

7. Alex Cukierman, RIP.
