Question 1

What does the Preregistered De Tc icon mean?

Accepted Answer

The Preregistered-DE-TC icon represents the Design and Endpoint preregistration badge with Time-stamped Comparison verification, indicating preregistered studies where time-stamped documentation enables verification that reported analyses match prespecified plans. This symbol identifies enhanced accountability through timestamping preventing retrospective modifications. The TC designation signals verifiable transparency through immutable preregistration records enabling direct comparison with published results.

Question 2

Where is the Preregistered De Tc icon used?

Accepted Answer

In verified transparency workflows, researchers submit preregistrations to time-stamped repositories like OSF creating permanent records preventing post-hoc modifications. Journal editors verify that reported analyses match time-stamped preregistrations preventing undisclosed analytical changes, while peer reviewers compare published results with immutable prespecified plans. The TC badge represents verification of authentic preregistration through time-stamped documentation demonstrating true a priori specification.

Question 3

What does the Preregistered De Tc icon tell users?

Accepted Answer

From a verification perspective, this icon signifies more than preregistration commitment - it represents verifiable transparency through immutable records, enables third-party verification of authentic prespecification, and provides accountability infrastructure preventing retrospective preregistration modifications. This distinction helps users recognize DE-TC as verified transparency with accountability mechanisms.
