This is from David L. Stern, who is not the David Stern who was formerly commissioner of the NBA:
…I am won over by the arguments that science papers should be made available freely to everyone as soon as authors feel that the work is complete. Posting papers to preprint servers is one good solution; I imagine there are others. (I prefer to call such documents open papers to remove the stigma associated with calling the work “pre” anything.) However, the discussion about the future of open papers has been imbalanced, with too much emphasis on the consequences of open papers for peer review and too little discussion of the fact that scientists are driven to publish in journals because of the existing incentive structure. The CV, and, specifically, journal names (and impact factors, journal reputation, etc.) are used extensively to judge scientists in competitions for jobs, promotions, and grant money. This is the main impediment to widespread adoption of open papers. I have heard many arguments about how it is too hard to change the structure of these competitions and that we should, instead, focus on producing great science in open papers, and let the culture-shift follow. In contrast, I think it is easier to change the incentive structure first; widespread adoption of open-papers will follow, like water flowing downhill.
