1. Democrats talking about their political problems, circa 1989.  (That was then, this is now!)

2. Achievement gap data.

3. Kinds of people, in universities.  Or is there only one?

4. Will inter-state war take place in cities?  And some reasons why India supports Russia.  And one Ukraine book list.

5. Correlations.  Cowen’s Second Law.  And regulatory diffusion.

6. How to overlook talent.

7. Are recommendation letters fair?
