A week of links

Links this week:

1. On the misplaced politics of behavioral policy interventions. And hawkish biases.
2. Noah Smith v Bryan Caplan on education signalling – 1, 2 and 3. I believe signalling is an important part of the education story, but Smith’s argument about costly signalling is on point.
3. Robert Trivers on his friends and enemies. HT: Razib

And if you missed it, my one post this last week:

1. Bad nudges toward organ donation.

Life continues to be busy, so posting will continue to be sparse.
