Junior biomedical researchers have long assumed that their hirings and promotions depend significantly on the amount of their published work. People responsible for making hiring and promotion decisions in the biomedical research field, however, are influenced much more by the overall impact that a candidate' s scientific publications have on his or her field than by the number of those publications. The information above, if accurate, argues most strongly against which of the following claims? ['Even biomedical researchers who are just beginning their careers are expected already to have published articles of major significance to the field.', 'Biomedical researchers can substantially increase their chances of promotion by fragmenting their research findings so that they are published in several journals instead of one.', 'Contributions to the field of biomedical research are generally considered to be significant only if the work is published.', 'The potential scientific importance of not-yet-published work is sometimes taken into account in decisions regarding the hiring or promotion of biomedical researchers.']
