All submitted manuscripts are read by the editorial staff. To save time for authors and peer-reviewers, only those papers that seem most likely to meet our editorial criteria are sent for formal review. Papers judged by the editors to be of insufficient general interest or otherwise inappropriate are rejected promptly without external review (although these decisions may be based on informal advice from specialists in the field). Manuscripts judged to be of potential interest to our readership are sent for formal review, typically to three reviewers, but sometimes more if special advice is needed (for example on statistics or a particular technique). The editors then make a decision based on the reviewers' advice, from among several possibilities: 

 Accept, with or without editorial revisions

 Invite the authors to revise their manuscript to address specific concerns before a final decision is reached

 Reject, but indicate to the authors that further work might justify a resubmission

Reject outright, typically on grounds of specialist interest, lack of novelty, insufficient conceptual advance or major technical and/or interpretational problems.
