Inaccuracies in medical textbooks?

Andrew Huberman discussed the inaccuracies in medical textbooks in a conversation with Rick Rubin. He recounted an instance where Rick Rubin asked Eddie Chang, a top neuroscientist, about the accuracy of medical textbooks. Chang estimated that only about half of the information in medical textbooks and training might be accurate. The implications of this are incalculable and highlight the limitations and evolving nature of scientific and medical knowledge. This underscores the fact that much of what is considered established knowledge can later be proven wrong or incomplete, posing significant implications for scientific progress 1.
