Questions the literature left open
Every survey here exists because a piece of research reached a conclusion nobody had measured directly. All are anonymous. All publish their results.
How these work
Anonymous by construction rather than by policy: no email, no account, and no database column that could hold one. Results are published while the survey is still open, so nobody waits for a report to see the findings and nobody has to take a summary on trust. Anonymised responses are released under CC BY 4.0.
Every survey is pre-registered with the evidence tier it may be graded at and the response count it needs before its data is quoted anywhere. Both are shown on the survey itself, set before the first response arrives.
