8 reasons I rejected your article

"A journal editor reveals the top reasons so many manuscripts don’t make it to the peer review process:

1. It fails the technical screening.

2.  It does not fall within the Aims and Scope.

3.  It's incomplete.

4.  The procedures and/or analysis of the data is seen to be defective.

5.  The conclusions cannot be justified on the basis of the rest of the paper.

6.  It's is simply a small extension of a different paper, often from the same authors.

7.  It's incomprehensible.

8.  It's boring."
