Medawar wasn't a whistleblower; he merely analysed, in his inimitable style, the fact that scientific papers routinely present the route to their results through a series of logical experiments, correct deductions, and obvious conclusions.
In practice, things rarely go as expected. Abortive experiments are abandoned, and results are tidied up to be presented in their strongest form. This is normal experimental practice, although it took someone of Medawar's stature to make it public quite so blatantly.
It is significant that Morton Meyers draws his examples from major medical innovations and can usually draw on the authors of those …
