While I think this is a stupid argument, I just wanted to point out what if there was a scientist out there with 401 peer reviewed papers on minute subjects, is his contribution automatically greater because he published 1 more article?
How many peer reviewed papers did Einstein & Hawking each write? If Collins has more papers are you going to claim he is superior than them?
I don't think you've thought this through.
Sorry, but again, you don't understand how things work. Certainly various journals have bigger impact factors than others. There can definitely be a scientist who has published fewer papers than another who has more of an impact, but not less by a factor of 10. If Dawkins were up around 200 papers, then the number difference wouldn't mean as much, and at that point I'd have to be in their field to evaluate the influence those papers had. I'd have to start looking at how often their works have been cited by others, which is definitely another metric that could be used. Certainly, some researchers, because of the pressure to publish, will try to get 2 or 3 papers where another would only get one with the same data. There are certainly other metrics involved, but number of publications, certainly along with the impact factor of the journals, is likely one of the most important. And again, I'm not saying anything about most important, as that is a very personal metric. I'm referring more to how scientists rate a persons contribution to the body of scientific knowledge. Also, I acknowledge along with most other scientists that this isn't a perfect system, but it is the system.
