[Drifts and pernicious effects of the quantitative evaluation of research: the misuse of bibliometrics].

The quantitative evaluation of scientific research relies increasingly on bibliometric indicators of publications and citations. We present the issues raised by the simplistic use of these methods and recall the dangers of using poorly built indicators and technically defective rankings that do not measure the dimensions they are supposed to measure, for example the <> of publications, laboratories or universities. We show that francophone journals are particularly susceptible to suffer from the bad uses of too simplistic bibliometric rankings of scientific journals.
