How Good Is Good Enough? - The Value of Impact Factor in Determining the Quality of Biomedical Research: A Review of Perspectives
The Journal Impact Factor is a Science Citation Index developed metric to evaluate the citations an article receives over a period of two years and serves as a surrogate marker to evaluate the quality of biomedical research. However, even though the calculation seems to be a straightforward mathematical equation, multiple confounders artificially impact the score- such as citing behavior, the region and language the journal is published in, and the ‘tip of the iceberg’ phenomenon. Despite an increase in metrics developed to alternatively gauge the prestige of research and the researcher- such as Eigenfactor Score, Article Influence Score and Google PageRank, the impact factor remains an essential instrument in dictating the scientist’s future in terms of job security, tenure extension, grant approval, and acquiring bonus, both hierarchical and monetary
