+Pre-registration is a mechanism in which one places a detailed description of a planned study into a repository where it is timestamped and will remain immutable.

+### Registered Reports
+
+Whenever possible, we support the submission of Registered Reports.
+
+Registered reports are a publication mechanism in which one submits a manuscript that contains an Introduction and Methods section that describe a study prior to execution of the research; it is essential a written version of a pre-registration.  
+The manuscript is reviewed on the strength of the rationale and methods, and if deemed sufficient it is given an "in-principle acceptance" such that the journal guarantees to publish the paper regardless of the results, as long as the approved methods were followed.
+
+There are currently [over 300 journals](https://www.cos.io/initiatives/registered-reports#tabid2) that accept Registered Report submissions.  
+In addition, Registered Reports can be submitted to [PCI-RR](https://rr.peercommunityin.org/), which is a community project that reviews preprint Registered Reports.
