Public Lab

The public lab publishes hypotheses, validation plans, and timestamps before an experiment runs, then publishes results regardless of outcome. Readers are invited to challenge assumptions, rebut the setup, or pressure-test the design before the results are in.

Preregistration Records

Hypotheses, validation plans, and results stay in one public record.
