1. Waste of resources: More than one manuscript will lead to a waste of time for editors and reviewers. Each journal has its own review process. If an article is considered by multiple journals at the same time, editors and reviewers of these journals need to spend time reviewing the same article, which is a great waste of resources.
2. Impairment of fairness: Multiple contributions to one manuscript undermine the fairness of academic publishing. Some authors may choose to withdraw their contributions from other journals immediately after receiving the first acceptance notice, so as to publish their articles in the shortest time. Those authors who have not received the admission notice have to wait longer, which is unfair to those authors who have made efforts but have not received timely feedback.
3. Impact on academic reputation: Multiple contributions to one manuscript will affect the academic reputation of the author. If an author is found to have contributed more than one manuscript, he may be regarded as dishonest and irresponsible by the periodical circle, which will cause long-term damage to his academic reputation.
4. Violation of ethical norms: multiple submissions violate the ethical norms of academic publishing. Most academic journals have clear submission rules, and usually it is explicitly forbidden to submit more than one manuscript. If authors violate these rules, they may face the risk of being rejected by journals, criticized by peers and even punished by academic institutions.
Therefore, in order to protect resources, maintain fairness, protect academic reputation, and maintain academic ethics, papers cannot be submitted for more than one manuscript.
