(p. 170) As early as 1945 the medical advisory committee reporting to the committee reporting to the federal government on a postwar program for scientific research emphasized the frequently unexpected nature of discoveries:
Discoveries in medicine have often come from the most remote and unexpected fields of science in the past; and it is probable that this will be equally true in the future. It is not unlikely that significant progress in the treatment of cardiovascular disease, kidney disease, cancer, and other refractory conditions will be made, perhaps unexpectedly, as the result of fundamental discoveries in fields unrelated to these diseases…. Discovery cannot be achieved by directive. Further progress requires that the entire field of medicine and the underlying sciences of biochemistry, physiology, pharmacology, bacteriology, pathology, parasitology, etc., be developed impartially.
Their statement “discovery cannot be achieved by directive” would prove to be sadly prophetic.
