But neither approach was reliable: it was hard to know which cases were similar, and dogmatists could choose from several sets of competing principles. The medical pamphlets promoting rival theories or expensive cure-alls would have sold well in modern airports, somewhere among the self help books, the management pot boilers, and the discussions of whether national economies should be inflated or deflated.
In other technical enterprises at that time, a potential buyer or investor might have asked to see previous work or whether the engineer himself had invested, but neither test was easily applied to medicine.
