Which of the following is a responsibility of each author?

One of the core responsibilities of each author in a scholarly publication is to confirm that the data are accurately presented in the paper. This is crucial because authors have a duty to ensure the integrity and credibility of the research they are associated with. Accurate representation of data affects the validity of the research findings and the trustworthiness of the scientific literature. Each author must be knowledgeable about the data and the conclusions drawn from it, which allows them to vouch for its accuracy during the peer review and publication process.

In contrast, while corresponding with the journal editor, directly observing data collection, and performing data analysis are important aspects of the research process, these responsibilities may not fall squarely on every author. For instance, one author may take on the role of corresponding with the journal editor, while another may focus on data analysis. However, all authors must agree on the representation and interpretation of the data presented in the publication, hence the emphasis on confirming accuracy as a universal duty among them.
