Links this week:

1. Marshall Sahlins says goodbye to the NAS.
2. A review of Jared Diamond’s The World Until Yesterday that is well worth reading (HT for these first two links: Andrew Badenoch)
3. There’s been bit of a storm over the last few days over a report by the Heritage Foundation on the cost of unlawful immigrants to the taxpayer. It’s co-authored by Jason Richwine – author of this book on IQ and immigration policy – and has been commented on by the likes of Reiham Salam and Dylan Matthews.
4. Dan Dennet and memes.
