Indicator Overlap: A Field Guide
By Aisha Patel
Overlap is not evil; unacknowledged overlap is. We list parent series and derivatives on the same page so learners see duplication.
Correlation is not causation, but it is also not independence. Heatmaps help until they become jewellery — we cap grids at what a human can narrate.
The goal is a map someone can defend in a hallway, not a poster that wins a beauty contest. If removing one indicator changes nothing important, it probably belonged elsewhere.
