Can Students Draw Better Election Maps than Professional Politicians?
Yes…at least in Virginia.
My collaborator Micheal McDonald and I are now just catching up to analyzing the data that resulted from the crowd-sourcing participative electoral mapping projects we were involved in. The results were surprisingly clear and consistent:
- Students are quite capable of creating legal districting plans.
- Student plans generally demonstrated a wider range of possibilities as compared to legislative plans.
- The ‘best’ plan, as ranked by each individual criterion, was a student plan.
- The student plans covered a larger set of possible tradeoffs among each criterion.
- Student plans were generally better on pairs of criteria.
- Student plans were more competitive and had more partisan balance than any of the adopted plans.
Most of these trends can be made clear through information visualization methods.
One of the visuals is below — it shows how each of the plans scored on different pairs of criteria. The blue elipses contain the student plans, the green ones contain the legislative plans, and the red lines show the commission plans. A tiny ‘A’ shows the adopted plan. In each mini-plot the top-right corner is where the theoretically best scores are.

Notice that blue elipses are almost always bigger, contain most of the green elipses (or at least the best-scoring parts) and extend further toward to the top-right corner. Go students!
