Regarding authorship practices, which statement is true?

Different disciplines have different practices about authorship, which is essential to understand within the context of academic publishing and research. Each field has developed its own norms and conventions regarding who qualifies as an author. For instance, in some disciplines, it may be common for research teams to include a wide range of contributors as authors, reflecting a collaborative effort in research. In contrast, other fields may have stricter criteria, where only those who have made significant intellectual contributions to the work are listed as authors.

The variability in authorship criteria across disciplines underscores the importance of transparency and clarity in authorship practices. Researchers must be aware of the norms specific to their field to ensure that all contributing members are appropriately credited and to avoid issues of authorship disputes.

In contrast, the other statements do not hold universally true. Not all fields follow the same authorship criteria, senior researchers are not the only ones who can be authors, and authorship is not limited to PhD holders, as many researchers contribute significantly to projects and may rightfully be listed as authors regardless of their degree. This context reveals the diversity and complexity of authorship practices in academic research.
