In some of the questions regarding author name, it is mentioned that people can use whatever they like, however, they must be consistent across their publications.
When it comes to being hired by a university for a tenure track position or by another principal investigator as a researcher, how can someone prove that they are the author of papers when their author name does not exactly match the one on their ID card? How can a principal investigator be sure that the publication list does actually belong to the person claiming them?
