“…Individual institutions and researchers are now classified on the basis of scientific productivity, usually established using the number of papers, the impact factors for the journals and the number of citations (see, e.g., Bishop, Gillet, Holliday, & Willet, 2003;Braun, 1999;Hirsch, 2005;Schreiber, 2008;Winkler, 2007).

In fact, the difficulty is to clearly understand what good science is and to know if data reflects quality.…”
