Challenges of finding and filling a gap in the literature
A significant original contribution to science is required for award of a PhD and for acceptance of any research article in RINAH. Most of us would agree that a significant contribution is one that fills a problematic gap in existing evidence and thereby advances the science in that field. It is relatively easy to recognize research designed well enough to contribute trustworthy knowledge, but it is much less easy to determine whether even a perfectly designed study fills a gap in the literature. Editors and reviewers must judge the value of manuscripts’ contributions, so I have been mulling over this problem.
