Why do inequalities endure, and what does “fairness” really mean? A Focus issue published by Nature Human Behaviour — Inequality and Fairness in a Complex World — explores these questions and their implications for research and policy. go.nature.com/4rr87ae 🧪

But the key chart for the current debate around The Left is this: different forms of #antisemitism by political leanings (far left to far right) *in Berlin*. It is, frankly, shocking.

I gave a talk in Sweden many months ago and haven't been reimbursed. The delay? The Swedish tax authority has to approve it. It should be routine. But they want me to go for an in-person identity check at the Swedish embassy. WTF? Dying to see the racial breakdown of whom this happens to.

Piff also has a long list of studies thag have failed to replicate. Even if the research isn't fraudulent, this makes a big mess for other people who then have to clean up the literature. The best work in this area finds no evidence that richer people are more antisocial.
