R.I.P. Rosling and Arrow

This month saw the passing of two giants. Not many people in history truly change minds. These two men did.

Kenneth Arrow: Among his many contributions, he proved that majority-voting will always lead to suboptimal results. There are many fine tributes linked here.

Hans Rosling: Among his many contributions, he showed time and again that what we believe about poverty and development is simply and tragically wrong. Tim Harford has a great More or Less podcast tribute. The NYT obit is good too.

May their ideas, influence, and spirits live on.
