Journal impact factor ‘distorts science’ › News in Science (ABC Science)

An international declaration by more than 150 leading scientists and 75 scientific organisations is demanding a rethink of the role ‘journal impact factor’ plays in the evaluation of research.

This ranking reflects the average number of times a journal’s papers are referenced or cited by other researchers during the preceding two years. Many institutions and funding bodies rate the success of a scientist based on the number of times they publish in a highly ranked journal.

But signatories to the declaration say the system is flawed because its use of an average, rather than median number of citations per journal, means highly cited papers can artificially lift a journal’s rankings.
