Who is right, the statistician or the surgeon?

Consider the case described below, from Peacock (1972). This passage seems to imply the young statistician is making a smart, correct statement.

But is he?

Answer

As the statistician did not make any statements, he cannot be wrong. He just asked two questions: 1) Did you have controls? and 2) Which half?

The surgeon is clearly wrong, unless a) Every patient he treated survived and b) No patient who was not treated would survive (or, of course, vice versa).

Both the surgeon and the statistician are making good points.
