Safety Or Utility?

摘要

Conceptually, we might think about the combined effects of safety and utility on the risk to which we're exposed as being represented by a curve expressing the safety results achieved for a given level of utility. Consider the chart at right and the three "curves." First of all, the vertical axis represents the fatal accident rate and the horizontal axis the level of utility achieved. Obviously, we could have perfect safety by choosing "zero" utility and just crouch in that lower left corner in the fetal position.
