Dear scientists,

If the scientific work was done by a team, and some of the team became authors of the publication, the latter are co-authors. When referring to this publication, each of them receives one citation. It does not matter the contribution of each of them. Is this fair? It seems to me that the scientific weight of the contribution of the individual co-author should not be equal to the scientific weight of the publication. In general, it is difficult to assess which of the co-authors worked harder. Maybe someone is a sponsor, and someone is the boss, and the main performer simply decided to please his benefactors. In this case, he sold (or shared) his achievement. This means that the total contribution (for example, a citation) should be divided by the number of co-authors. This will be a fair assessment of the individual collaborator.

Otherwise, an injustice arises in relation to the single author, who took upon himself all the costs. After all, if two publications (1 author and 4 co-authors) turned out to be in the same journal at Scopus or the Web of Science, then it must be assumed that the quality of works is comparable, but the number of beneficiaries is 4 times more for the second article. We must distinguish between the scientific weight of the article and the scientific weight of the contribution of the scientist to this work.

Research Gate conducts work on the evaluation of scientific interest to a separate article. Can the scientific weight of one article be divided by the number of co-authors to estimate the scientific weight of one scientist? Otherwise, each co-author will get 1 unit of impact of the article and the total will be, for example, 4 units. Even if one of the co-authors has not made an effort. But this is a collective contribution! It must be divided by the number of co-authors.
