A terminology problem.
Method A of doing something has an accident rate of 100/whatever. Method B of doing the same thing has an accident rate of .01/whatever. The accidents caused by method A kill an average of one person. The accidents caused by method B kill an average of 1000 people.
Now, we would coolly judge B to be safer than A. There is no question, however, that B’s accidents typically kill more people, and on that basis are more noticeable.
Is there a common phrase for this? Do we call it “concentration of risk”?
