Links this week:

1. Two pieces on diet. First, an excellent article on how the poisons in vegetables might be making you stronger. Second, a new study in the fat-carb wars.
2. Andrew Gelman on the strength of statistical evidence.
3. Two excellent podcasts. Gregory Clark on social mobility (and the genetics behind it) and Paul Sabin on the Simon-Ehrlich bet. Some of my thoughts on Julian Simon are here and here.
4. Economists are happier. The reasons? More cash and religion.
