Person A suggested to person B that they implement a certain existing methodology, X, to solve problem Y. And offered to lead by advising while B be the driving force. Now B found another key question than the one offered by A, modified methodology X and got (new publishable) results. During the process, B did the coding, the testing, all the writing. Now how should the credit be assigned in the authorship of such paper?

Field: Numerical Optimization

My suggestion is that both authors be treated as equal contributors. That is to say that neither contribution seems "greater" than the other.

However, the contributions are a bit qualitatively different and if you want to spell that out, though not everyone thinks it necessary, write a contributions section (or acknowledgements) in which you mention the specific contributions of each.

This seems pretty close to pure math, actually, where the assumption is equal contributions. It is possible in math for someone to make a vital, indispensable, contribution to a paper in a five minute conversation in which they supply the key insight lacking in the other(s).

But your description describes the more normal back-and-forth in which each contributor advances not only the product but also the understanding of the other. Author order could be alphabetical as is typical in pure math.

I do, however, have a bias toward equal contribution in all but edge cases. And I am a co-author on one of those edge cases. It was obvious and so we made an exception.

I also fear there is a dispute lurking behind your question. I suggest you try to work beyond that. Such disputes don't lead to future collaboration that might be beneficial to everyone. Generosity may even be called for. Pistols on the Green at dawn isn't a good long term career strategy.

  • Thanks a lot. I'm inclined to put their name but not on the basis of ethics but, because I don't want to get into a lot of conflicts. I am a young female at the beginning of my career and he is senior to me. At the same time, I don't want to come across as a naive person or somebody that can be used in my cohort. What looks ethical to me is that ethical collaboration should mean that everyone contributes equally in all endeavors. I am not going to collaborate with them again bc, I would not ask to be a co-author if I were in his shoes.
