The Tyranny of International Index Rankings

International index rankings are popular, but perhaps too persuasive. They emphasize country differences where similarity is the dominant feature. Rankings based on Doing Business, the Human Development Index and Freedom House can be misleading, not because of wrong indicators, but because the estimation of the scores ignores inherent uncertainty. Re-estimated with a method that captures this uncertainty, it becomes clear that ranking every adjacent country is a rather courageous activity.
