Scholars who publish research with hundreds of co-authors should receive no more than one-third of the current credit they get for such papers, according to a proposed formula designed to eradicate ¡°gift authorship¡±.

Under the mooted new scheme, those who contribute to co-authored papers would receive only a fraction of a research credit for their contribution, instead of the full authorship credit that they now enjoy.

The plan has been put forward by Louis de Mesnard, professor of economics at the Universit¨¦ Bourgogne Franche-Comt¨¦ (UBFC), amid growing concern over the limited contribution of some researchers on papers with hundreds, and sometimes thousands, of co-authors.

With many papers now citing at least 1,000 authors ¨C the current record stands at 5,154 for a 2015 paper published by the team at the Large Hadron Collider at the European Organisation for Nuclear Research (Cern) ¨C critics say that researchers gain undue credit for minimal input into a project, thus making it impossible for universities to recognise and reward true scientific talent.

Some academics have also set up ¡°publication clubs¡± to artificially boost their outputs, in which a ¡°small group of scholars¡­mutually agree¡­to co-sign each other¡¯s papers, even if they have not really been involved in writing them¡±, adds Professor de Mesnard in a paper titled ¡°Attributing credit to co-authors in academic publishing: the 1/n rule, parallelization and team bonuses¡±, last month.

To combat the problem also known as ¡°gift authorship¡± or ¡°byline banditry¡±, some critics have suggested dividing credits for a paper between authors, which would see, for example, each author gaining a 10th?of a credit if there are 10 co-authors.

That approach (known as ¡°1/n¡±, where n equals the number of researchers) is ¡°too harsh¡±, particularly when those involved in so-called kilo-authored papers would receive very minimal credit for their work, says Professor de Mesnard, who believes that this method would discourage academic collaboration.

Asking scholars to assess their own involvement in a paper and take a proportionate credit is another option, but is ¡°unsatisfactory and utopian¡±, he adds.

Instead, Professor de Mesnard suggests a ¡°completely new approach¡± called ¡°parallelization¡±.

Under the formula ¨C where credit = (n+2)/3n ¨C if a paper has two co-authors, then each would receive two-thirds of a credit, while a paper by three authors would see each of them gain 5/9ths of a credit.

For papers with a very large number of co-authors, each researcher would receive no less than one-third of a credit.

In the case of the 2015 Cern paper with 5,154 co-authors, this might seem ¡°too generous¡± but it is ¡°above the 0.02 per cent allocated by the 1/n rule¡± and ¡°is clearly below the unfair credit of one full paper per co-author¡±, Professor de Mesnard explains.

The approach would give a far more accurate reflection of the research volume now undertaken, he adds. He compares the current sharing of research credit?to the biblical miracle of?Jesus?feeding?thousands of people with a few pieces of food as?a handful of papers are potentially able to sustain the careers of thousands of academics.

¡°This new approach is feasible and fair and it credits genuine cooperation in academic publishing,¡± says Professor de Mesnard.?¡°It could give rise to a new way of comparing scholars, especially for recruitment and promotion.¡±
