https://youtu.be/gQECBNFk980 The past 60 years have seen huge advances in science that should have raised the efficiency of commercial drug research and development. Yet the number of new drugs approved per billion US dollars spent on R&D has been cut in half every 9 years since 1950, falling around 80-fold in inflation-adjusted terms. So why have we seen an exponential decrease in productivity, even though we are in the most advanced period of drug research and development ever?
