Consider the thousands of medical professionals who spoke out against lockdowns, or masks, or vaccinating into a pandemic when the virus was sure to mutate, or the risk that mRNA needed more testing, or the efficacy of ivermectin, or anything else that differed from the consensus. They were all ostracised, many lost their licenses, many doctors and nurses here in New Zealand still haven't gotten their jobs back and we are desperately short of medical staff. How likely is it that next time someone will bravely speak out what they believe? Practically none. That means that medical science can no longer correct mistakes. Every mistake becomes dogma that can never be overturned. That only leads to bad places.
