I have come to the conclusion that we need to do a meta-study of studies?! No, not the Cochrane Meta-analysis type but rather a study about the usefulness of studies. Asking questions like: “Did this study change anything in the field?” “How much suffering and pain was reduced by the application of this study?”.Now this could be in medicine or any other field for that matter. I am guessing that the most common result would be ” nil”.But there is the outside possibility, due to the perverse incentives in studies(i.e. greed or professional ambition or pushing an ideological line) that studies would have a negative impact on outcomes. We hear talk about the military/industrial complex and the medical/pharma complex.But no-one is talking about the academic/study complex. It is a huge industry that may outweigh all the others. It certainly does already in reputation. Any volunteers to fund this study?! I doubt it lol
