While it is common practice in the health field to use validated descriptors available in thesauri or glossaries, in other fields it is apparent that researchers use the terms they feel are most appropriate. By ignoring accepted terminology, their work may fall off the radar of database searches. An example of this is the choice of keywords that are not associated with validated descriptors. As a direct consequence, literature reviews in some areas, particularly in the social sciences, may produce results with increasing levels of error. I believe that this issue should be the subject of further reflection and debate.
