A question, a project to track, a data point to correct? Write to us.
Suggest a project to grade
Name the project and, if possible, its sources. We prioritise the best-documented and most-debated cases. One independence note: we never grade on behalf of a party, for or against — the grade follows the method, not the requester.
Report a correction
Any data point can be corrected on evidence. The most effective route is a GitHub issue (source required, declaration of interest requested); validation is reviewed by a maintainer. Otherwise, email us.
