Reading language
The screen, the questions and the judgments read in English where an English reading has been made. The Korean originals are unchanged, and evidence stays in the language it was written in.

The city that got worse among the alleys that got better Did the average change, or did the world that makes up the average change?

Read from the start

What this series asks

  • Are changes in outcomes mixed up with changes in composition?
  • Does the same unit of aggregation mean the same target as before?
  • What grounds justify carrying a partial trend over to the whole or to a new group?
