And when a doctor dies, you can expect a good diagnosis as to the cause of death. All Hill and Doll had to do was wait.
More than 40,000 doctors responded to Hill’s request, but not all of them were delighted. You have to understand that smoking was extremely common at the time, and it was no surprise to find that 85 percent of the male doctors in Doll and Hill’s initial sample were smokers. Nobody likes to be told that they might be slowly killing themselves, especially if the suicide method is highly addictive.
Очень хороший поворот ума – к тому, как собирать достоверные данные.
