" But there is a lot of fuzziness in the notion of "intellectual contribution." In some academic units, for example, junior scholars are expected to list their department chairs or lab chiefs as coauthors on all their publications, whether or not these people have actually contributed anything to the paper. In fact, I have heard some senior academics argue that they should be listed as coauthors on anything written by anyone being paid out of their grants. The polite term for this is honorary authorship or gift authorship, a practice that is officially frowned upon by journal editors but that remains relatively common. "
