Sir Richard Doll is famous for proving that smoking causes cancer, but I hope that, after a recent disclosure, he also becomes famous for having no integrity whatsoever. It turns out that Doll took money from the devil--otherwise known as Monsanto--for twenty years. During this period, Doll was "investigating" cancer risks within the chemical industry. For $1,500 a day, Doll found the inspiration to declare that Agent Orange did not cause cancer.
Doll also found the inspiration to forget to mention that he was on Monsanto's payroll. And that he was also on the payroll of the Chemical Manufacturers Association, Dow Chemicals and ICI. For this gig, he "proved" that vinyl chloride does not cause liver cancer, a finding disputed by the World Health Organization.
