Collaboration is encouraged because it is believed to improve academic research, supported by indirect evidence in the form of more co-authored articles being more cited. Nevertheless, this might not reflect quality but increased self-citations or the “audience effect”: citations from increased awareness through multiple author networks. We address this with the first science wide investigation into whether author numbers associate with journal article quality, using expert peer quality judgements for 122,331 articles from the 2014-20 UK national assessment. Spearman correlations between authors numbers and quality scores show moderately strong positive associations (0.2-0.4) in the health, life, and physical sciences, but weak or no positive associations in engineering and social sciences, with weak negative/positive or no association in various arts and humanities, and a possible negative association for decision sciences. This gives the first systematic evidence that greater numbers of authors associates with higher quality journal articles in the majority of academia outside the arts and humanities, at least for the UK. Positive associations between team size and citation counts in areas with little association between team size and quality also show that audience effects or other non-quality factors account for the higher citation rates of co-authored articles in some fields.Citation
