Do not resuscitate: the journal impact factor declared dead

Science is a highly competitive business so measuring the impact of scientific research, meaningfully and objectively, is essential. The journal impact factor (JIF) has emerged over the past few decades as the most used scientific metric for the assessment of research quality. As a research scientist, Medical Research Institute Director and former Editor-in-Chief of a scientific journal, I have to confess my own way too common use of the JIF, and to delight when that particular parameter fell in my favour. But the truth is the JIF has major flaws. There are better ways to gauge the impact of a piece of research, the quality of an individual researcher and even the quality of a peer-review journal. The San Francisco Declaration on Research Assessment attempts to formally address the deficiencies in the JIF measurement and proposes the adoption of different practises in assessing quality of research publications ... While JIF may have some limited value in assessing journal quality, for the individual or individual piece of research the JIF is even less reliable.  In the context of peer-reviewed publications at least, what’s important is the frequency with which others cite that individual’s publication, preferably in a way that considers the variability of the size of different scientific fields.  One day, it even may prove to be significant to give 'bonus marks' for individuals publishing highly cited papers in low impact journals. Such metrics are being developed and are becoming more commonplace.  One example is the h-index, proposed by physicist Jorge E. Hirsch in 2005, which is a metric that links both the number of papers an author has published with the number of times those papers have been cited. While emerging metrics themselves have deficiencies (for example your h-index generally gets better as you get older!) they are part of an important trend.  The Declaration on Research Assessment is signed by an impressive list of influential individual scientists and organisations as well as the editors-in-chief of many major journals, including Science.  To some extent the declaration states what many in research in this country already know and have begun applying to their judgements of individual researchers and of the quality of scientific studies. However, the declaration is probably that clear line in the sand that the scientific world needed in relation to JIFs.  It is the next development that will be the most interesting: a time where we look beyond simple publication metrics to judge more fully the impact of a piece of research. For example: [1] what resources (online or otherwise) were produced as a result of the work? [2] how many people accessed these resources? [3] what impact did the work have on policy and practice? [4] what was the economic, social or environmental benefit of the work? ..."
