What happens next

A follow-up record is a promise to look again. Evaluators revise their estimates as new studies, costs and monitoring data come in. Keeping a dated copy of what GiveWell said lets anyone see, later, whether the estimate held up.

How you can tell it hasn't changed

Each record carries a fingerprint: a code calculated from every word and number in it. Change a single character and the fingerprint changes. Each record also carries the fingerprint of the one before it, so the records form a chain, and editing any earlier record would break every link after it.

The fingerprints use SHA-256, a standard public method, so anyone can recompute them.

What this record is not

  • It is not a measured result. It records what GiveWell estimated, and when.
  • It is not our rating. We don't score charities; the figure is GiveWell's, copied exactly.
  • It does not change any ranking. Follow-up records are kept separately from the pages that list charities.
