If you wanted to buy a product, and the main source of research on the product was the company selling it, would you automatically assume the product was safe and effective?
But you see, that’s the just the beginning of the problem. Suppose the company’s research was cited thousands of times in the press, as the authoritative standard of proof—and anyone who disputed that research was labeled a conspiracy theorist and a quack and a danger to the community and an anti-science lunatic.
Would you begin to suspect the company had some awesome media connections? Would you suspect some very powerful people were backing the company?
This is exactly the situation with the US Centers for Disease Control (CDC).
