Having collected data, it can be tempting to publish several articles on the same dataset. However, there is a difference between publishing articles with clear overlap, and distinct studies. In short, when the overlap is sufficient so that the studies could have been combined for a more impact article, it is not good. It distorts the literature and wastes the time of the reader, reviewers and editors.

Data overlap is acceptable in the case where: There are different and distinct questions with multiple and unrelated endpoints; and /or the data collection is large or drawn out that it is impractical to publish all simultaneously and other researchers would benefit from earlier publications.

Academy of Management ethics video series:

Ethics Video Series: Slicing the Data in Publications

This third in a series on Ethics of Research and Publishing discusses questions of: When is a paper really new? Can I publish more than one paper from a survey data set? ; Can I submit two similar papers to journals, one of which had two dependent variables and the other paper two different dependent variables but shared independent variables in common?
