Author! Author! Do All Scientific Papers Really Need To Identify So Many Of Them?

Researchers hold mixed opinions, with some advocating a streamlined approach that credits only germane contributors Geophysicist Marcia McNutt routinely reads a stack of journals ranging from the Journal of Geophysical research to Science and Nature. When she reads a paper in any of these publications, she usually feels safe making a few assumptions about the authors listed on the paper.

"I assum if there is a senior person who is last author, whether that's second or thid, that that is the person who probably wrote the proposal to fund the research and had the idea to begin with, but generally did not personally carry out the research.

"And then, if there is an intermdeiate author, I usually assume that is a person who had some sort of significant input--such as providing a key data set or perhaps working on some key subset of the problem--but was not the person who physically wrote the paper and did more than 50 percent of the research."
