When a research is carried out by a team, each participant’s contribution is important and, in an experimental study, sometimes even a single parameter measured by somebody can be of a key importance for interpretation of results. When I compose a research team I cannot predict whose input will be the most significant, but a tacit agreement always was that each member of this team would have authorship rights. To put aside ethical considerations, who would agree to work with me otherwise? Now, however, the Medical Journals' Editors community has decreed that, in order to qualify for authorship, a person should meet four (sic!) strict criteria established by these pundits. So those who do not qualify as authors must be moved to the Acknowledgment section of the manuscript.
In my opinion, this is a gross violation of scientific community’s rights – does anybody disagree?
