original_url | string | yes | URL for the paper that contained the original experiment - always use http://doi.org/{DOI} if available |
replication_url | string | yes | URL for the paper that contained the replication experiment - always use http://doi.org/{DOI} if available |
description | string | yes | One sentence description of the effect that was found in the original paper which the replication paper attempted to replicate |
result | “success” OR “failure” OR “inconclusive” OR “reversal" | yes | Result of the replication – success, failure, inconclusive, or reversal. Human or AI judgement here. If stats are available, additional judgements will be calculated and put in new rows. |
