This licensing has profound costs for human life. Although there is no scientifically serious empirical evidence that IRBs save any lives by overseeing research under the human-subjects research regulations, it is abundantly clear that they suppress vast amounts of medical knowledge, and they thereby leave large numbers of individuals without the information they need to live.
Put simply, IRBs kill. Whenever the government suppresses life-saving medical knowledge, it predictably kills those who need it. And nothing is more effective in suppressing such knowledge than the licensing of speech and the press.
