Academic publishing is a fundamental requirement for career advancement as an academic. However, much research makes use of the unpaid input of patients, students and the general public. They believe that the research will be used to better the lives of people.
What actually happens is that the research is used to attract funding to build research empires, to fill offices with drones doing PhDs, to fly to conferences.
I'm still reeling from reports of a €500,000 project to improve dementia care that has spent almost all that money on academic salaries and has so far produced not a single tangible change in services for patients or their carers.
With millions of publications, you would think that the world would be a healthier place. Unless that was never the point.
