Buela-Casal G, Zych I. What do scientists think about the impact factor? Scientometrics online pub.22 Febr.2012
This study reflects the opinion on the impact factor (IF) of a broad sample of scientists all over the world. A questionnaire was answered by 1,704 researchers from 86 different countries. The results show that the opinion is slightly above a "neither positive nor negative" median. Surprisingly, there is a negative correlation between the number of articles published by the respondents and their opinion on the IF, that is more articles they have, the less they believe that IF is a good metric.
