Perhaps you have better insight into this, why do you think having the primary incentive for professors/researchers being quantity of papers published is appropriate? Or are you saying that it's simply unfixable and we must accept this? As far as I'm aware, quantity of papers published has no relevance to the value of the papers being published, with regard to contributing to the scientific record, and focusing on quantity is a very inappropriate and misleading metric to a researcher's actual contributions. And don't downplay that it isn't purely a numbers game for most people. Your average professor has their entire career tied to the quantity, from getting phd candidates through in a timely manner to acquiring grants. All of it hinging on quantity.
