Preregistration
Recording a study's hypotheses, design and analysis plan in a time-stamped public registry before the outcome data are observed. It separates confirmatory tests of predictions from exploratory analyses generated after seeing the data, which makes undisclosed analytic flexibility easier to detect. Preregistration does not make a study correct, and deviations from the plan are acceptable when they are reported transparently. How one could reason about recording a catharsis-like change of state: signals, features, inference and context, baselines, self-report, error costs and ethics, and why every step stays uncertain. Nothing on this site measures anyone. Every public claim on this site with its type, evidence level, confidence, sources and review date, and an appraisal of each reference. How claims are graded, how art is kept apart from evidence, and how to report a problem. The works the definition rests on, with the level of evidence each was appraised at. (2018). The preregistration revolution. doi:10.1073/pnas.1708274114 Supports the definition of preregistration and the argument that it distinguishes prediction from postdiction. Advocacy by proponents of the practice; it does not measure the effect of preregistration on research quality.Where the site uses it
