Brian Nosek, a professor at the University of Virginia and director of the Center for Open Science, says, “Academic publishing is the perfect business model to make a lot of money. You have the producer and consumer as the same person: the researcher. And the researcher has no idea how much anything costs.” Nosek finds this whole system is designed to maximize the amount of profit. “I, as the researcher, produce the scholarship and I want it to have the biggest impact possible and so what I care about is the prestige of the journal and how many people read it. Once it is finally accepted, since it is so hard to get acceptances, I am so delighted that I will sign anything — send me a form and I will sign it. I have no idea I have signed over my copyright or what implications that has — nor do I care, because it has no impact on me. The reward is the publication.”
