Via reader Norm, I learned about a new study using brains scans that suggest that people are aren’t nearly as self-interested as some might think and that inequality makes people unhappy. “The scientists speculate that people have a natural dislike of inequality. In fact, our desire for equal outcomes is often more powerful (at least in the brain) than our desire for a little extra cash. It’s not that money doesn’t make us feel good — it’s that sharing the wealth can make us feel even better.”
