The Unitary Executive Notes on how people know things

Sunstein posted an admirably frank essay yesterday on the Unitary Executive Theory:
How he participated in this elite bipartisan political consensus —
and how he has been persuaded by overwhelming historical evidence that he & other high-ranking lawyers were wrong.

Sunstein on Valuing Children’s Lives Cass R. Sunstein (Harvard Law School; Harvard University - Harvard Kennedy School (HKS)) has posted Valuing Children's Statistical Lives: A Conceptual Framework on SSRN. Here is the abstract: A longstanding puzzle for regulatory theory and practice has been the valuation of children's lives, or more precisely, the valuation of mortality risks faced by children. There is data about parents' willingness to pay (WTP) to reduce such risks, and that data might be used to produce a Valuation of Statistical Lives (VSL) for children.

Legal Theory Bookworm: “Imperfect Oracle” by Sunstein The Legal Theory Bookworm recommends Imperfect Oracle: What AI Can and Cannot Do by Cass R. Sunstein. Here is a description: Imperfect Oracle is about the promise and limits of artificial intelligence. The promise is that in important ways AI is better than we are at making judgments. Its limits are evidenced by the fact that AI cannot always make accurate predictions—not today, not tomorrow, and not the day after, either.
