1)This Megan McArdle post is interesting, but perhaps it suggests that the converse is true: that low-performing schools should mimic the high-performing ones and instead devote more resources to bringing up students who are already strong?

2)This post on empathy and the unseen is very good.

3)I also really liked this Julian Sanchez post on the perils of pop philosophy.

4)How regulation screws up our lives: let me count the ways.
