We need INDEPENDENT replication

We always need replication in scientific studies. I therefore can´t understand why there is now such a fuzz in Nature as they

… took the unusual step of soliciting an independent verification of the paper during the process of peer review. This is the first time that Nature has obtained second-party replication ahead of publication.

this could have saved thousands of dollars if it would have been also applied to other studies before, yea, yea.
