The premise that coauthors on papers make equal contributions is in itself grossly biased. They don't. I'm coauthor on papers I've never even read. If you were looking at the class of Scott Locklin on papers I'm named on, assuming everyone is supposed to get equal credit, using the methods they did, I'd be considered to be unfairly not getting enough credit, because there are less of me than everyone else and most of the papers I'm in, I do not deserve equal credit. The proper comparison class is, do principal authors get equal credit for their contributions, normalized to their proportion in the population.
