Every year hundreds of young university students enroll in scientific research groups to make contributions to multiple fields of science and technology. The most frequently used way to disseminate knowledge is through scientific articles, which are published in specialized journals. The desire to increase scientific production can influence the occurrence of bad practices and lack of ethical principles by authors and collaborators, and young researchers may be forced by the workgroup that hosts them to incur them. This paper shows the most common cases of lack of ethical principles in scientific research in which new researchers may be involved due to the obligation of their work group. Some solutions to this problem are proposed so that new researchers can have a non-traumatic start on this path of scientific research.
